There are many methods to complete AIA Billing in the contracting industry. While each of those methods may vary from one Contractor to another, Total Office Manager has integrated this process to work based on data that is entered into the software. Many Contractors are used to filling out the AIA Payment Application then entering in an Invoice based on the information contained on the Payment Application. This practice was typically performed because there was not an easy or computerized method to tie everything together. In the world of Accounting, before you send an Invoice to a Customer, you must first enter it into you accounting software so that it increases your receivables. The AIA Payment Application is simply a Standardized Invoice which you are requesting payment for the job you are currently working. Using the Progressive Billing feature in Total Office Manager will make completing the AIA Payment Application easier.
