What are Accounts Payable Outsourcing Services?

Accounts payable outsourcing is the process of delegating your firm's purchasing cycle—from invoice ingestion and PO matching to approval routing—to a dedicated offshore team.

Instead of paying a domestic staff accountant $80,000+ a year to scan invoices, forward-thinking CPA firms deploy offshore AP talent. Our specialists work directly inside your existing infrastructure (like Bill.com or Ramp), enforcing strict segregation of duties so payments are processed rapidly without risking fraud.

Data entry is a mathematically proven low-margin activity. Allowing your expensive US-based accountants or controllers to process invoices restricts firm growth. Offshore AP clerks remove this bottleneck immediately.

Service Architecture & Process Flow

1 The Invoice Ingestion Layer

The journey begins with automated receipt and invoice extraction. Your offshore AP team manages a dedicated vendor inbox (e.g., AP@yourclient.com) and utilizes Optical Character Recognition (OCR) tools to extract raw data.

Crucially, our team steps in where automation fails. AI gets confused by handwritten adjustments, poorly scanned PDFs, and complex multi-line tax breakdowns. Your human AP associate audits the OCR scrape instantly, fixing misread numbers before they pollute the general ledger.

2 Three-Way PO Matching & GL Coding

For inventory-heavy or construction clients, AP outsourcing is critical for the Three-Way Match. Our professionals cross-reference the supplier's invoice against both the origin Purchase Order (PO) and the Receiving Document.

We prevent duplicate payments, flag short-shipments, and assign precise multi-dimensional GL classes, locations, and departments mapped to your client's chart of accounts.

3 Segregation of Duties & Approval Chains

Security is paramount. Outsourced accounts payable services operate via strict segregation of duties. The offshore associate has system permissions to enter the bill, attach the source document, and route it to the specific U.S. manager using software like Bill.com.

They do not have the authority to release funds. By removing the processing burden from the US team, domestic managers only have to log in on Fridays, review perfectly coded bills, and click 'Pay'.

The AP Workflow

What does an Outsourced AP Clerk do?

An outsourced AP professional takes ownership of the entire procurement-to-pay workflow, ensuring vendors are paid accurately while maximizing early payment discounts.

    Monitoring dedicated AP inboxes, resolving OCR read errors, and ensuring correct general ledger coding before routing.

  • Three-Way PO Matching

    Verifying that the supplier invoice matches the issued purchase order and the receiving report to prevent overpayment.

  • Approval Workflow Management

    Chasing down department heads for invoice approvals based on custom authorization matrices.

  • Vendor Statement Reconciliations

    Reconciling monthly statements from high-volume vendors to ensure no duplicate payments.
