Supplier List Form


Sub Pay App

*Note: Allow 5-7 business days for internal processing of electronic pay application documents. If you need to bill immediately, contact Doster for a paper version. This will not affect your ability to submit electronically on future applications. Doster Construction uses a Sage accounting product that allows an electronic interface. The driving engine for the interface is the status of the invoice as is reflected in accounting. As the electronic pay application can only pull information that has become a part of the accounting database, frequently a timing issue for pay applications will occur. To overcome this issue, we allow the field for “previous applications” to be over written by the subcontractor. If the field populates correctly, no entry is needed. If the field is incorrect, key in the accurate data.

Step One: (Step one is only required to be completed once per company. If completed previously, proceed to Step two.)

Complete the Agreement for Electronic Submission of Subcontract Application for Payment and return the paper copy, via mail with an original signature, to: Attn: Sub Payables 2100 International Park Drive Birmingham, AL 35243 (fax or e-mail copies will not be accepted)
