Accounts Payable Outsourcing Companies Built for High-Volume E-Commerce
3-way matching, marketplace fee reconciliation, and multi-vendor AP management that scales with hundreds of invoices a month—without hiring another AP clerk.
Why Standard AP Outsourcing Falls Short for E-Commerce
Most accounts payable outsourcing companies build their process around one vendor database and a clean PO-to-invoice trail. E-commerce doesn't work that way.
Your invoices come from suppliers, marketplaces like Amazon and eBay, Shopify billing statements, and fulfillment partners—often four different formats landing in four different inboxes. Traditional 3-way matching alone can't untangle marketplace fees, refunds, chargebacks, and commission adjustments that show up weeks after the original sale.
Add volume: hundreds of invoices a month across hundreds of SKUs and supplier relationships. Manual coding at that scale isn't a staffing problem you solve by adding one more clerk—it's a process problem that needs automation.
And purchase orders themselves break down. Marketplace orders often have no traditional PO at all, and fulfillment partners frequently bill retroactively for storage, pick-and-pack, or return processing fees you didn't see coming. Standard AP setups aren't built to catch any of this.
Our E-Commerce AP Approach: 3-Way Matching + Platform Reconciliation
Invoice Capture and Coding
Supplier invoices and marketplace billing statements are captured and coded through your procurement system or our dashboard—no manual re-entry across formats.
3-Way Matching with Marketplace Fallback Logic
PO, receipt, and invoice are matched automatically. Where marketplace orders have no PO, fallback rules validate against order and settlement data instead.
Marketplace Fee Reconciliation
Monthly statements are reviewed against transaction logs to catch disputed chargebacks, refunds, and seller fees before they inflate COGS.
Supplier Communication and Dispute Resolution
Duplicate invoices, quantity mismatches, and underbilling across your vendor network are flagged and resolved directly with suppliers.
Payment Timing Optimization
Payment runs are scheduled to capture early-pay discounts where available, without straining working capital.
Beyond the headline numbers, the savings compound in places most in-house teams don't have bandwidth to check:
- Duplicate payment prevention — high-volume, multi-channel billing creates slip-ups. Systematic review catches duplicate supplier invoices and marketplace re-billing before they hit the bank.
- Landed cost variance analysis — tracking supplier pricing trends and freight charges across shipments feeds directly into cost-down negotiations.
- DPO management — extending payables strategically without damaging supplier relationships or forfeiting early-pay discounts.
Integration with QuickBooks, Xero, and Your Accounting Stack
AP outsourcing only works if it fits into the system you already run. KVG integrates with QuickBooks Online, QuickBooks Desktop, Xero, NetSuite, SAP, and Zoho Books, with two-way sync so invoices post to the correct expense accounts in real time.
Configure once, run on automation — set your 3-way matching tolerances (price variance threshold, quantity overage limits) a single time, and matching runs against those rules going forward.
Bank reconciliation built into AP — cleared checks and ACH payments are matched back to invoice records as part of the same process, eliminating the split reconciliation that usually happens between AP and bank recs.
Audit trail and approval workflows — every invoice routes through your existing control matrix. You retain sign-off authority; we remove the manual bottleneck of getting there.

E-Commerce AP Case Study: Reconciliation Under Volume
Challenge: A New Jersey off-road automotive e-commerce seller was reconciling invoices from 40+ suppliers, three fulfillment partners, and two marketplaces—over 1,200 invoices a month with a 5% error rate.
Solution: KVG implemented automated 3-way matching with marketplace statement reconciliation, set price and quantity variance thresholds, and integrated the entire workflow with QuickBooks.
Result: Error rate dropped to under 0.3%. Marketplace fee leakage of $18,000 annually was recovered through statement review. Cash conversion cycle improved by 4 days through DPO optimization.
