Accounts Payable Outsourcing Services for US Businesses on QuickBooks and NetSuite
Accounts payable outsourcing means an outside team runs your invoice-to-pay cycle: capturing bills, matching them, routing approvals, paying vendors and closing the books. Acgile provides accounts payable services to US e-commerce, SaaS, manufacturing and automotive companies, working directly inside your QuickBooks Online or Oracle NetSuite account on hours aligned with your time zone.
You keep approval authority, and payment batches go out only on your sign-off. We do the processing, the matching and the month-end cleanup. Since 2017, our QuickBooks ProAdvisor and NetSuite-certified accountants have run payables for companies that have outgrown a part-time bookkeeper but don't yet need a full in-house AP department. In one engagement, a line-level vendor billing review uncovered about $919K in 3PL overcharges that had built up over three years.
Tell us your monthly bill volume and system. We'll review your setup, flag what's missing and show you how we'd handle it.
Where accounts payable breaks as a company grows
AP usually works until invoice volume outgrows the person doing it. Then the same problems show up in roughly the same order:
- Bills sit in inboxes. Invoices arrive by email, vendor portal and mail, and nobody owns the queue. Late fees follow, and so do vendors who put you on credit hold.
- Payments go out without a match. Without a check against the purchase order and the receipt, you pay for short shipments, wrong prices and the same invoice twice.
- Approvals live in Slack threads. There's no record of who approved what, and that's the first thing an auditor or lender asks for.
- The vendor file decays. Missing W-9s, old bank details and duplicate vendor records turn January 1099 season into a scramble and open the door to payment fraud.
- Month-end runs late. Unrecorded bills and stale accruals mean the P&L you review on day 15 still isn't right.
Each of these is a process gap, not a software gap. Fixing it takes someone who owns the workflow every day.
What we handle
What our accounts payable outsourcing services include
Our AP management covers the full invoice-to-pay cycle. Hand us all of it, or only the parts that hurt.
Invoice capture and coding
We collect bills from a shared AP inbox, vendor portals and your capture tool. Then we enter each one with the correct GL account, class, location and department. You get coded, searchable bill records in your own system, not a spreadsheet sitting beside it. For high-volume work, our invoice data entry team scales with you.
Two-way and three-way matching
Before anything is paid, we check the invoice against the purchase order (two-way) and, for inventory and goods, against the item receipt (three-way). Price or quantity variances outside your tolerance go back to the buyer as exceptions. In NetSuite, this also keeps the Accrued Purchases account from filling up with unmatched receipts. Here's how we clear three-way match variances in NetSuite.
Approval routing
We set up and follow an approval matrix: who approves which vendors, departments and dollar amounts. Every approval is recorded in the system, so you have an audit trail without chasing emails.
Vendor onboarding, W-9s and 1099s
We collect a W-9 from each new US vendor before the first payment, check the name and taxpayer identification number (TIN), and flag vendors who will need a Form 1099. For payments made in 2026, the federal filing threshold for Form 1099-NEC and most 1099-MISC boxes is $2,000 per vendor, up from $600 (IRS: About Form 1099-NEC). We track vendor totals against that line all year, so January is a review, not a hunt.
Payment runs
We prepare scheduled payment batches by ACH, check, wire or card, grouped by due date and any early-payment discount. Your approver reviews the batch and releases it. We then record the payments and apply vendor credits in the ledger.
Vendor statements and bank reconciliation
We reconcile vendor statements against your AP ledger, chase missing credits and answer "where's my payment?" emails from a shared inbox. Bank and credit card accounts are reconciled too, so cleared payments tie out.
Month-end AP close and accruals
At close, we accrue for goods and services received but not yet billed, reverse prior accruals, clear the accrued-purchases balance, and reconcile the AP subledger to the general ledger. It feeds straight into our month-end close work.
AP reporting
You get a weekly AP aging, a cash-out forecast for the next two to four weeks, and a monthly summary covering invoice volume, on-time payment rate, days payable outstanding (DPO) and discounts captured. Need a different format for your CFO? We build custom management reports.
Backlog and AP audit cleanup
If your payables are already behind, we start by clearing the backlog: finding duplicate vendors and payments, applying open credits, closing stale bills, and tying the aging to the balance sheet. For years of historical errors, our financial cleanup team takes the books back to audit-ready.

AP software, an outsourced team or an in-house hire?
Many small businesses start by searching for accounts payable software. Software automates capture and payment, but someone still has to code, match, chase and reconcile. Here's how the three options compare:
| AP software alone | Outsourced accounts payable (Acgile) | In-house AP hire | |
|---|---|---|---|
| Who does the work | Your team | Our accountants, in your system | Your employee |
| Exception handling and vendor follow-up | Your team | Included | Included |
| Month-end AP close | Your team | Included | Included, if skilled |
| Oversight | None | AP manager oversight included | Your controller |
| Typical cost driver | Per-user or per-invoice subscription | Flat monthly plan ($1,350–$4,200) | Salary, benefits, payroll tax |
Many clients use both: the software captures and pays, and we run it.
Your accounts payable team
Every client gets a dedicated resource at the level their payables need, with direct oversight from an AP manager.
AP Clerk and AP Analyst: your accounts payable specialist
An AP Clerk (2 years' experience) handles high-volume invoice processing, matching, coding and the vendor inbox. An AP Analyst (2–4 years) also resolves billing discrepancies, runs multi-currency processing and vendor aging analysis, and owns 1099 tracking and audit readiness. Either way, the same specialist learns your vendors, so you aren't re-explaining every week.
AP Manager
An AP Manager (5+ years of leadership) designs the end-to-end AP workflow, sets fraud controls, forecasts cash outflow and handles vendor escalations and negotiations. For companies without a controller, this is the person who works directly with your CFO or owner. Our founder, Zain Tareen, still reads the books.
Why US companies choose Acgile for payables
$919K in vendor overcharges found

$2.3M defended for a US manufacturer
We rebuilt accounting, EDI and dispute handling for a consumer goods manufacturer with multi-year NetSuite reconciliation backlogs: 3,076 Home Depot disputes closed, $668K directly tracked, and a repeatable monthly close.
System depth, not just data entry
QuickBooks ProAdvisor and NetSuite-certified accountants who handle three-way match variances, saved searches and accrual clearing, as well as bill entry.
Track record since 2017
11 client reviews on Clutch, and Top Rated Plus on Upwork with a 100% Job Success score.
Industries we run payables for
AP looks different in each business, and our accounts payable solutions follow the bills you actually get:
E-commerce
Supplier invoices, 3PL warehouse and fulfillment bills, freight, marketplace fees and EDI retailer chargebacks. Standard AP review rarely catches 3PL errors, because blended 3PL invoices hide overcharges. We check them line by line, and we pair AP with marketplace inventory sync.
Manufacturing
Raw material POs, item receipts, landed cost and three-way match on every inventory bill.
Automotive
Parts suppliers, core charges and returns, and vendor credit tracking.
SaaS
Software subscriptions, contractors who need 1099s, prepaid expenses and card reconciliation. More on our SaaS accounting services.

What accounts payable outsourcing costs
Cost depends on scope more than on a per-invoice rate. The main drivers are:
- Monthly bill volume and how many vendors you pay
- Share of bills that need PO and receipt matching
- Number of entities, currencies and bank accounts
- How clean the current ledger is (backlog cleanup is scoped separately)
- Whether we also handle AR, close or reporting
Each plan is a dedicated AP resource at a flat monthly rate.
