Harry W. Hepburn IV, AIA, LEED AP - Principal


We worked closely with Lynne Kloes. She was friendly, professional, understanding, responsive, and trustworthy. All traits that we look for when selecting people/companies to work with. Lynne helped us navigate some complex accounting issues within our ERP system. Lynne was able to help guide us through both cleaning up the books and preparing us for a transition to a new software. I would highly recommend Lynne and Outsourced Accounting Services for any company needing accounting services, and any company considering a software transition. With Lynne's help, we were able to make corrections and updates needed so that our books were up-to-date moving forward. We have confidence in her abilities and her understanding of accounting and ERP software, which allowed us to move ahead.

Irving Yee - Principal

Irving Yee Architecture, PLLC

Mary from OAS got me up and running to using Unanet myself in less than a couple of months. As an architect running a business, it felt daunting to put systems in place, but Mary made it easy. I really enjoyed our phone calls. There was nothing I felt I could not do or accomplish with OAS’s steady guidance. Before meeting OAS, I wasted hours on doing my accounting manually and now doing timesheets and accounting is easy. I don’t get overburdened with unnecessary information. OAS has taught me a very simple way to input information into Unanet so I can use it with efficiency. I enjoy partnering with Mary on our Zoom calls as she makes using Unanet so easy and friendly. If you want a partner who is able to get you on track with Unanet quickly, I recommend OAS.

Redd Ferguson - Accountant


Working with OAS has been a life saver. Our original implementation did not go as well as we were hoping and had some major hurdles to jump through once we started to figure out the program. The OAS team members were all major players in making our lives a little more productive. No matter the challenge or the issues we had – they were always ready and willing to help. Each member of the team has been great to work with!! We are so thankful to have found OAS and look forward to continuing our working relationship for years to come.

Tim Workinger - Chief Financial Officer


I wanted to give a shout out to Martha Ibey Griffith, CPA for all the hard work and dedication to making our Unanet software switch such a success. The process of change is never easy, but when you have strong vendors helping, it makes it all worth it. I personally recommend using Martha. I truly thank you for all that you have done.

Kelsey Crossey - Business Manager

Claitman Engineering Associates

Thank you for your help. I really appreciate Jessica's quick response to take a call with me today and to explain things so easily. I look forward to working with you more this year.

Stephen Cooper - Senior Operations Consultant


Our firm has recently switched from another consultant to OAS for Unanet support and training. The OAS team has been very responsive and knowledgeable. They were quick to understand our needs and proposed some excellent custom solutions to the challenges we face. Most recently, I had the opportunity to work with Amy on some SQL programming and dashboard design issues. She was awesome! In just two quick training sessions, we solved challenges we have spent months trying to resolve on our own.

Lori Lingenfelter - Office Manager

LLC Engineering and Surveying, Inc.

I just wanted to send a quick note of appreciation for Tammy and all that she has done to get us up and running on Unanet. She's very knowledgeable, patient, and easy to take direction from. We're so happy that she's our lead in getting us through these beginning stages!

Stephanie Mamone-Kolcun - Principal Structural Engineer

SEI Engineers, Inc.

I just wanted to let you know how wonderful Jessica Gandy has been. She is super-efficient and wonderful to work with and has been especially helpful with some of the payroll issues we have been dealing with.

Marci Pick - Vice President


I’m not sure I could have handled our transition from Quickbooks to Ajera without Kristen and OAS! Our implementation (headed by another firm) didn’t go great but Kristen wasn’t worried when she started working with me to get our books sorted out (and me up to speed on how to work within Ajera). She has been integral in helping us create processes and keep everything honest and clear.

Jennifer Rovan - Office Manager

JPT Architects, P.C.

We are a smaller firm that was using a limited system for operations. After reviewing several new systems, we decided that Unanet and OAS were the way to go and we are so happy with the decision! Mary is very knowledgeable and was able to walk me through setting up the system and entering previous information needed. The transition was seamless. Unanet has given our Project Managers the ability to track their own projects to make sure they are on budget. Mary and her team promptly replied to questions and trained our employees on the basics. Mary continues to answer questions when needed. I would highly recommend OAS to everyone! Thank you, Mary and the team at OAS!

Carol Pontrello - Human Resources Manager

ATSI, Inc.

It was a pleasure working with Martha. She did a wonderful job for us during our implementation and was very fun to work with!

Jennifer Dillon - Billing Administrator

Sevee & Maher Engineers, Inc.

We switched to Unanet A/E after running a proprietary invoicing system for 10+ years.  Mary and Paul from OAS assisted our team over the past 10 months, from general learning and training to creative solutions to address our unique business practices and OAS delivered.  Thanks to our internal IT department and OAS, we were able to go live with very few surprises.  Unanet A/E has allowed us to bring 3 external invoicing and accounting systems under one umbrella and OAS was instrumental in making this happen.  Thank you, Mary and Paul, for excellent and responsive training and support.

Mary Scudieri - Accounting Manager

XDD Environmental

We recently converted to Unanet A/E and OAS guided us through the entire conversion, implementation, and training process.  Martha from OAS is very knowledgeable and personable so it is a pleasure working with her.  Martha responds quickly to any questions or calls for help.  I will continue working with OAS and highly recommend them to others.

Vicky Hewey - Finance & Operations

base design group, inc.

The OAS team is incredibly knowledgeable, accessible, and helpful in both accounting expertise and software implementation. Our team switched to Unanet AE this past year and Martha with OAS was our lifeline in training, implementation, and troubleshooting. We received patient assistance in countless redesigns of our invoices, quick and helpful responses to emails, and the helpful direction to many other useful resources from the Unanet support site. This team is great!

Emily Preston, PE - President

Compass Infrastructure Group

I just wanted to reach out and say thank you to you guys for your help getting us up and running with Unanet. You have far exceeded my expectations for the implementation process, and have made the process seamless. I was extremely nervous/unsure of what to expect in terms of the time, effort, and cost for implementing an accounting/timekeeping software. Both Gary and I knew that getting a system going would help us long term with growth opportunity, adding employees, and saving us time and headaches for reporting, invoicing, employee tracking, taxes, FAR audits. And already it has saved me SOOOOOOOOO much time, and it’s all thanks to you guys and how easy you have made the process for us. I’m looking forward to continuing to work with you for needs as they come up. And will be recommending Unanet and you to other small businesses in Ohio. Being a small business owner isn’t easy, but this has definitely made it easier, I can’t tell you enough how thankful I am to get to work with you.

Marcy Burchett - Financial Controller

Budinger & Associates, Inc.

We found the team at OAS to be friendly, insightful and talented. Our admin staff is always able to get prompt in-person help for our Unanet software. After switching from another consultant, OAS was able to quickly put our staff in the driver's seat. We would recommend OAS to anyone switching to or trying to get more from Unanet A/E.

Linda Dunlap - Office Manager

Slone Architects and Interior Designers

Slone Architects and Interior Designers hired Outsourced Accounting Services to prepare us to change accounting software to Clearview InFocus.  Mary Boyd is an excellent Trainer.  She is very knowledgeable with InFocus, and explains the software very clearly.  She took her time in training and was patient; going over things more than once, until I understood the software.  I am so glad we chose to use OAS.  I learned much quicker with Mary’s training than if I was trying to learn it on my own.  Also, Paul Natalizio was very knowledgeable and easy to work with in customizing our invoices and checks.  Another thing that is very important is that OAS is available.  They are quick to respond with any questions or problems that arise.  We still use Outsourced Accounting Services today, and plan to in the future.  I highly recommend Mary Boyd and the employees at OAS.

Mark D. Grizer, CPA, CGMA - Controller / IT Associate


“I am writing this testimonial to you in appreciation for your support to our firm. Many of our calls are unscheduled and require time to resolve.  Your staff has always been more than cooperative and understanding in giving us the attention required.  It is clear that you have the full understanding of the Deltek products which is essential to filling the gaps in our understanding of how to properly use the system to maximize profitability. We are also impressed in your use of the Excel tools to draw and organize data from Deltek's database to provide information as needed.  While Deltek support is always available to us for program functionality, you provide a service at a higher business level.  I am more than happy to recommend Outsourced Accounting Services to others.”

Terri Smondrowski - Director of Corporate Services

Keystone Engineering Group

Over the past 11 years, it has been a pleasure to work with the OAS team.

Paul at OAS is always reliable and available to support our personnel when we have issues or solutions we are looking for while using the Deltek program.   Not only is Paul and the OAS Team available to assist us but their team if very knowledgeable.  Our company has grown from 15 employees to 60 employees in the past 11 years and Paul has been there every step of the way guiding us in new areas we want to explore from project resource tracking, electronic imports and setting up new billing systems to be efficient.

The OAS team is extremely friendly and they care about their clients.  I can honestly say that we have more than a working relationship and I feel that we have built a friendship along the way.  I would highly recommend working with OAS and you will not be disappointed.

Cathi S. Groomes - Accounting Manager

architecture inc.

“I have been using services provided by Outsourced Accounting Services for a little less than a year and love working with Mary Boyd and Paul Natalizio. The company has top notch Professionals that provide excellent customer service.  Every time that I have contacted OAS, I have received a call back and a resolution for the reason why I called or emailed on the same day. I would highly recommend using their services for any help with Deltek Vision Accounting Software. We have used them for training and support for our Architectural Firm. Paul is extremely knowledgeable, very easy to work with, and always willing to make time to help us out. One of the most important reasons why you should use OAS is that they are very reasonable in cost and I have complete trust in them and what they do.”

Susan Roth - Controller

GCI Consultants, LLC

We met the OAS crew at our very first Deltek Convention in Nashville.  It was the beginning of a partnership with our team and theirs as we began our Deltek Vision journey.

OAS has continued to be instrumental in each step in our Deltek pursuit within our Engineering firm, recently assisting with our Multi-Company platform transition.  It was a massive undertaking that we could not have achieved without their guidance and milestone approach.

Using OAS reduced our stress and enabled us to think outside the box, by not limiting our capabilities to take the next steps into VantagePoint.  Their knowledge and willingness to work alongside each of our team members is invaluable.  Knowing resolution is a phone call away provides a safety net that is not always available in larger firms.

As we continue to grow, we anticipate the OAS team to be with us each step.

Shawn Crowley - Associate Principal, BIM Manager

Tevebaugh Associates

“As a 10-person architecture firm with an out-of-date and complex accounting procedure, we began searching for support to refocus our process, but it was not economically feasible to maintain a full-time accounting manager. We were referred to Outsourced Accounting Services (OAS). OAS has played a key leadership role in our transition to new accounting software (Deltek Ajera).  They have enabled us to streamline what was a daily arduous process into an efficient and accurate bi-weekly review. In the end, we have eliminated prior accounting mistakes and saved substantial time and money. Teaming up with OAS is one of the strongest business operations moves we have made!”

Shirley Johnson, P.E., C.E.M., G.B.E., LEED® AP - Accounting Manager

Furlow Associates, Inc.

“We highly recommend the services of Mary Boyd and Outsourced Accounting Services, LLC.  She is very competent, knowledgeable, and efficient.  She provides excellent coordination with our clients and is always professional and thorough.  Mary is an asset to our firm because she has greatly improved our accounting process, saving us time and money.  She made our conversion to InFocus very smooth and easy.  She is always available to answer questions and is a valuable resource to our firm.  You will enjoy working with Mary and her firm!”

Vincent J. Cichocki, P.E. - President

Furlow Associates, Inc.

“Mary has been providing us with bookkeeping services since August 2010.  She is consistently competent, thorough, and professional in her work.   She also provides consulting with the Deltek Vision program and she has used her knowledge to help us streamline some of our processes and procedures in using this program.  Mary has become a real asset to our company and we highly recommend her. “

Tim Schroeder, AIA, CDT, LEED AP - President

Neumann Monson Architects

When our (staff) accountant decided to go out on their own, OAS was able to jump in and take full operation of our (internal) accounting needs within two weeks – all from 1,000 miles away. Our operations didn’t skip a beat and we actually became more efficient in the process. At the same time, we were changing our ERP system and OAS provided skilled expertise in both systems that eased the transition. We deeply appreciate the help and wholeheartedly recommend OAS.

Laurie Schauss, CPA - Controller

Cates Engineering, Ltd.

“Our firm has been working with OAS for a few years now.  We had an idea in mind of a report we’d like to have that would help us manage our day-to-day operations, but it wasn’t available with our software platform (Deltek Vision).  OAS was recommended to us, so we called them and described our vision of the report to Paul, our consultant.  He worked with us to develop a report that is exactly what we envisioned.  We update it weekly, print it out, and post it for all employees to review.  He took our “impossible” idea, put it in an Excel format that interfaces directly with our Deltek Vision software, and then added a few extras to make it better. OAS has always responded quickly to anything we’ve requested.  They are easy to work with and they provide reliable estimates up front for the work they think will be involved in the project.  I would highly recommend them.”

Danette Steffish, PE, LEED AP - Business Manager / Associate / Senior Mechanical Engineer

Bruce E. Brooks & Associates

BBA has really appreciated the attention to detail and correctness that OAS has put into every task.  They maintain this level of quality while working very efficiently.  They are extremely responsive, with a high expectation for timeliness for themselves.  This is paired with flexibility for the schedules and demands of their busy clients.  Their services have made our invoice delivery and monthly book closure a streamlined process, consistently completed earlier than ever before, and kept us on top of the weekly tasks culminating in the month end.

Sandy Telegraphis - Office Manager

PennTerra Engineering, Inc.

In a world where time is money, how wonderful it is to pick up the phone and have my questions answered quickly and professionally by Paul Natalizio of Outsourced Accounting Services, LLC. He consistently goes above and beyond to help me understand the process needed to solve our accounting issues and has been my “go to” for support with Deltek Vision for years. Paul takes a confusing situation and by using patience and persistence, finds a solution to my questions. His efforts are admirable and very much appreciated. We highly recommend the services of Mary Boyd and Outsourced Accounting Services, LLC.

Patrick Lowry - President

Alta Vista Solutions

Mary {OAS} has been absolutely extraordinary at reducing our accounting costs, streamlining our financial processes, while at the same time maintaining our monthly financial reporting requirements.

I love the fact we get to tap into someone like Mary without the big fat paycheck (and drama) that typically come with someone at that level.

Using OAS we reduced our payroll in our accounting department by over 30% and eliminated our reliance and costs for outside consultants when attempting to resolve issues associated with Deltek Vision (our accounting software).

James Tortorici - Accounting Manager

Roux Associates, Inc.

I have worked with OAS for almost 10 years and have always been impressed with their responsiveness.  Mary and her team are friendly, knowledgeable, and insightful.  When we were struggling with the benefit accruals, OAS jumped right in and got us up to speed.  Appreciate all the support!

Margaret Rachnowitz - Controller

Roux Associates, Inc.

“Paul Natalizio is great to work with and continues to be awesome!  He has helped many of us in our HR and Accounting departments.  I don’t know what we would do without him!”

Chad Tompkins - CEO

WTC, Inc.

OAS has done a great job helping us utilize our accounting software to its full potential.  They are knowledgeable and fast!  WTC would recommend OAS to other small A&E firms looking to improve their project accounting.

Pat Hunnewell - Vice-President

Blue World Construction, Inc.

Paul and OAS stepped in and were critical in supporting our growing construction firm through several months of accounting support while our bookkeepers and in-house financial staff were on maternity or extended personal leave.  Paul spent time with them before leave began, developing an understanding of our current processes, and even improving and providing better training on the use of Clearview InFocus, which not only helped us through their absence, but improved our processes upon their return.  Paul and OAS have become a valuable resource we’ll continue to call-on to support our in-house financial and accounting staff for many years to come.

Cheryl Ierardi - Accounting Manager

P.W. Grosser Consulting

“It is with great pleasure that I recommend Mary Boyd and Paul Natalizio IV from Outsourced Accounting Services.  We have used their services for many years and have always received great service.  Outsourced Accounting Services respond quickly with thoughtful and accurate results. We have used their services to set up tailored features in Deltek Vision that provide PWGC with valuable information as well as troubleshooting difficult problems.  Having Accounting Specialists and Deltek Vision Specialists in one company, make them unique and immensely valuable.”

Stephanie Picone - Manager of Office Administration

Scherer Design Group, LLC

We used OAS to support our engineering firm in acclimating to a new software platform for all accounting steps and project database storage.  Paul was always readily available to assist and very knowledgeable on all topics.

Fred Shear - Operations Director

Davidson & Associates Construction Analysts

“Outsourced Accounting Services provides high quality professional services with a friendly, personalized approach. Whatever the matter, be it running payroll, gathering tax season data, or an end-of-month press to finalize invoices, it is a pleasure to work with Mary and Paul.  We benefit from OAS' experience working with small but busy professional firms such as ours. They listen to our particular needs and strive to meet them, providing more than just off-the-shelf services.  OAS has added value to our business by making themselves available beyond regular business hours when a critical or late-breaking circumstance emerges, performing as team members rather than as a simple vendor of services.  We recommend Outsourced Accounting Services for your professional firm.”

Linda Allen - Director of Finance

Core States Group

“We went through an in-house conversion to Deltek last year, and Mary and her team were recommended to facilitate and manage the conversion to ensure everything was handled properly from an accounting perspective. They came through right when we really needed their expertise, and they were a lifesaver for our Accounting team during the conversion. A year later, they are still providing technical and professional advice on any questions or issues that arise. It is a pleasure working with the OAS team, and they have been very responsive, knowledgeable and available as needed in finding solutions to help us continue to move forward with our business. They have been very responsive, including working with us after hours and on weekends as needed. We would strongly recommend the OAS team as a professional Deltek consulting firm.”

Anthony J. Vitullo, CPA, CGMA, MBA. PhD - Chief Financial Officer

Arora Engineers, Inc.

Outsourced Accounting Services (OAS) first provided services to Arora in 2012 when Arora found it needed extra billing help in the Accounting department. OAS continued to remain part of our regular billing operations many years later. OAS became an integral part of Arora’s business management process by providing reliable and dependable Deltek Vision accounting, billing, and training services to meet our ever-changing needs and supporting our growth. Even as we have more than doubled in size since originally engaging OAS, we at Arora Engineers have found continuing value in the services and strategic assistance that OAS is able to provide to our financial operation. I would recommend without reservation OAS and Mary Boyd, whom I have had a business relationship going back to a software conversion in 2008, for your outsourced accounting requirements.

Anne Morgan - Office Administrator

CCG Facilities Integration Incorporated

"My relationship with OAS has benefited me and my company beyond expectations knowing I can always rely on their expert direction.  I benefit from working with OAS knowing when I cannot work through an issue in Deltek Vision they will walk me through so I understand what needs to be done.  The most important thing you should know about working with OAS is they are always professional, friendly, and VERY patient.  I would highly recommend OAS to any firm that needs guidance in the Deltek Vision system.”

Myroslava Slonova

Acheson Doyle Partners Architects, P.C.

“Mary Boyd is a creative problem solver who provided myself and my firm with great value for our consulting dollars by offering real solutions and very effective processes that better automated my job duties.  I also was pleased with her willingness to schedule sessions after the close of the regular business day so that we could work uninterrupted.   I would highly recommend Mary Boyd and Outsourced Accounting Services.  She is a pleasure to work with and she will always make you and the needs of your firm a top priority.”

Frederick Holland - Chief Operating Officer

Ike Kligerman Barkley Architects

“Outsourced Accounting Services is a vital partner in our business.  From the on-site Deltek training at the beginning of my tenure through their seamless integration as my billing department for three months when my accounting manager was on leave, Mary and Paul have been professional, efficient, and available whenever we have needed them.”

Anthony J. Saccento, CPA - Director of Finance

Ike Kligerman Barkley Architects

“Working with Mary Boyd has been a very productive and satisfying experience.  She has solved every problem and her rates are very fair.  I highly recommend her as a top-rated Deltek consultant.”

Chip Ryan - VP Finance

Aerosol Monitoring & Analysis, Inc.

“After having issues setting up and using the Deltek Vision System, I was introduced to Mary Boyd by a colleague. Mary presented the information in a hands-on, common sense approach. She provided good personal service with basic explanation of the different processes and how to utilize Vision to our benefit. In addition, she showed and explained each process' pluses and minuses. After working with her, the system became an understandable tool for our company.”

Rita Berryman - Bookkeeper

ABHA Architects

I don't know where I'd be without Paul's help sorting through issues with the new JV Organization setup in Vision--he's been great!  We expect to have smooth sailing from here, but if not, it's nice knowing that we can work with OASLLC for help.

Pat McClane - Chief Financial Officer


“Mary Boyd has provided the technical assistance we needed to implement changes to our system, but she has also made recommendations for best practices in the industry and ways to process our work more efficiently.  For a small company, we have a rather complex structure which Mary grasped immediately and translated into the accounting software.  I derive a great deal of comfort knowing that she has the accounting background, as well as the knowledge of the software to get the job done.  She has always been responsive and has provided her services in a timely manner.”

Toni M. Watson - Director of Finance and Personnel

Kibart, Inc.

"I feel very lucky to have worked with you (OAS) during our conversion to Vision.  You truly provided me with an amazing foundation that encouraged me to deepen my own knowledge of the system and develop it in ways that have really benefited both me and our company."
