Integrating with Tenant & Applicant Processing, Purchase Orders, Fixed Assets and the General Ledger, Accounts Payable is another important module of the Lindsey Software system. Not only does Accounts Payable simplify the tasks of invoice entry and check printing, but it also generates a variety of other documents as well: Section 8 Invoices by PHA, HUD 2516 Minority Vendor Reports and IRS 945 Back-Up Withholding documents.
