Company Information Gathering

Your first 90 days with ADA are critical. That's the period of time we use to learn about and understand your business and accounting processes.

Within the first 48-hours you will meet the Technical Team, Accounting Team, Customer Care Team and we shall upload all the data from your Complete Accounting questionnaire.

Processing Information - Final Reporting

The Team is now processing your accounting files and the documentation of your processes and procedures has begun. The first set of A/P and A/R accomplished and processed within the first week. During the next two weeks our Team will contact you to make sure that all your accounting needs are being met and to learn about any other questions or concerns you may have. In the final weeks, our Customer Care Team will provide the first set of monthly financial reports to review. Documentation and our accounting process continues.
