IAI has the privilege of working with many quality vendors.
As part of the maintenance contracts IAI’ holds, we are often responsible for ordering supplies, scheduling subcontractors and processing payments to vendors on behalf of our clients, making those purchases/invoices directly billable to IAI, and taxed accordingly.
IAI is required to have an IRS Form W-9 on file for all active vendors. Please help us keep your vendor profile up to date by providing a current W-9 form. (Click here to download the W-9 form from the IRS website.) Electronic copies may be emailed to accounting@iaiwater.com or you may also mail/fax a copy by using the contact information listed below.
Vendors may elect to complete the IAI Vendor Packet, which will ensure that they are included in our list of IAI Best Vendors. This list is provided to all of IAI’ Project Managers and locations, for their convenience when ordering supplies or procuring services.
How to Become an IAI Best Vendor
