- Maintain up-to-date supplier records in QuickBooks and ensure all invoice documentation is attached and saved in the designated vendor folder.
- Verify all vendor bank account or remittance change requests by calling the vendor at a phone number already on file (not the number provided in the request) and obtain Accounting Manager approval before updating payment details.

- Reconcile and attach check remittances to invoices; mail checks by the morning of the next business day.
- Communicate with vendors regarding payment status, issues, and follow-ups.
- Ensure vendors who require a W-9 have one recorded in QuickBooks under the vendor record and saved in the vendor folder.

- Review monthly vendor statements, particularly for supplies and dumpster vendors, to ensure all invoices are up to date, and follow up with the vendor on any missing invoices.
- Maintain utility vendor files and ACH payments. Log in to the bank daily to monitor utility ACH payments, track utilities for all shops, and ensure we are not paying for any closed shops.
