Turn your AP function from a bottleneck into a strategic advantage

Accounts payable outsourcing moves your entire vendor payment process - invoice receipt, data capture, coding, approval routing, 3-way matching, payment execution, and vendor communication - to a dedicated external team. The average company spends $12-$15 processing a single invoice in-house when you factor in staff time, error correction, and duplicate payment recovery. Our managed AP service brings that cost below $5 per invoice while improving accuracy and turnaround. We capture invoices from any channel (email, mail, portal), validate them against POs and receiving documents, route approvals electronically, and schedule payments to maximize early payment discounts. The result: your vendor relationships improve, your cash flow is optimized, and your accounting team is freed from the most tedious part of their week.

End-to-end accounts payable management

Invoice processing & data capture

Every vendor invoice is captured within 24 hours of receipt - whether it arrives by email, mail, or vendor portal. We extract header and line-item data, code expenses to the correct GL accounts, and verify against your chart of accounts. OCR technology handles high-volume scanning, while our specialists verify every field for accuracy. Invoices are indexed and searchable in your system from day one.

3-way matching & approval routing

Every invoice is matched against the purchase order and receiving document before approval. This 3-way match catches pricing discrepancies, quantity variances, and unauthorized charges before you pay. Approved invoices are routed electronically to the right approver based on your rules - by amount, department, vendor, or GL code. No more paper invoices sitting on someone’s desk for two weeks.

Payment execution & discount capture

We schedule payments strategically - capturing early payment discounts (typically 1-2% for paying within 10 days) while preserving cash flow by paying on optimal due dates. Payment batches are prepared for your review and approval before execution. We support ACH, wire, check, and virtual card payments. A 2% early payment discount on $500,000 in annual payables puts $10,000 back in your pocket.

Accounts Payable FAQs

Accounts payable outsourcing is the practice of delegating your vendor invoice processing, payment management, and related tasks to an external specialist team. This includes receiving and capturing invoices, coding expenses, matching against POs, routing approvals, scheduling payments, maintaining vendor records, and handling payment inquiries. The goal is to reduce processing costs, improve accuracy, and free your accounting team from the most labor-intensive part of their workflow.
AP outsourcing typically costs $3-$8 per invoice processed, depending on volume and complexity. A business processing 500 invoices per month might pay $2,000-$3,500/month. Compare this to in-house processing at $12-$15 per invoice ($6,000-$7,500/month for the same volume). Most businesses save 50-65% on AP processing costs, plus additional savings from eliminated duplicate payments and captured early payment discounts.
For businesses processing more than 100 invoices per month, outsourcing AP almost always makes financial sense. The cost savings are significant (50-65%), but the operational benefits matter more: zero duplicate payments, faster processing times, captured early payment discounts, better vendor relationships, and your accounting team freed for higher-value work. The main consideration is choosing a provider with robust controls and security - which is critical when someone is handling your money.
AP automation refers to software tools (like Bill.com, Tipalti, or BILL) that digitize invoice capture and approval workflows. AP outsourcing provides the human team to operate those tools and manage the entire process. They’re complementary, not competing - the best results come from combining both. We work with your existing AP automation tools and add the human expertise for exception handling, vendor communication, and quality control that software alone can’t provide.
We manage the complete AP cycle: invoice receipt from all channels (email, mail, portal), data capture and GL coding, PO matching and 3-way verification, approval routing and follow-up, payment batch preparation, payment execution (ACH, wire, check), vendor statement reconciliation, 1099 tracking, vendor master maintenance, and payment inquiry handling. We also provide monthly AP aging reports and cash flow forecasting based on upcoming payment obligations.
Our multi-layer duplicate detection checks: (1) Invoice number against existing records for the same vendor. (2) Amount and date matching against recent payments. (3) PO number cross-reference to ensure the same PO isn’t paid twice. (4) Vendor statement reconciliation to catch discrepancies. Any potential duplicate is flagged and held for review before entering the payment queue. Our duplicate detection rate is 99.8%.
Yes, 3-way matching is standard in our AP process. Every invoice is matched against the purchase order (confirming authorized purchase, agreed price, and quantity) and the receiving document (confirming goods or services were actually received). Discrepancies in price, quantity, or specifications are flagged and resolved with the vendor before the invoice is approved for payment. This prevents overpayment and catches billing errors.
Absolutely - discount capture is a key value driver. Common vendor terms like 2/10 net 30 offer a 2% discount for payment within 10 days. Our 24-hour invoice processing and expedited approval routing ensures these windows aren’t missed. For a business with $1M in annual payables with discount-eligible vendors, capturing even half the available discounts yields $5,000-$10,000 in annual savings - often more than the cost of the AP service itself.
We work with all major platforms: QuickBooks Online and Desktop, Xero, Sage 50 and Intacct, NetSuite, SAP Business One, and Microsoft Dynamics. For AP automation tools, we support Bill.com, Tipalti, BILL, AvidXchange, and Stampli. We work directly in your system - no parallel tools or duplicate data entry. For clients without AP software, we can recommend and set up an appropriate solution.
Accuracy is ensured through multiple controls: 3-way matching validates every invoice before approval. GL coding is reviewed against your chart of accounts. Payment amounts are verified against approved invoices. Bank details are confirmed against the vendor master (with secondary verification for new vendors or bank detail changes to prevent fraud). Post-payment reconciliation against vendor statements catches any discrepancies. Our payment accuracy rate is 99.95%.
