Accounts Payable Outsourcing Services
A managed accounts payable service, not another piece of software. A trained U.S.-led offshore team runs invoice processing, vendor management, payment scheduling, and 1099 tracking inside your own systems – with multi-layer review before anything reaches your desk.
What Is Accounts Payable Outsourcing?
Accounts payable outsourcing is handing the full invoice-to-pay cycle to an external team that processes invoices, codes expenses, manages vendors, and schedules payments on your behalf. Instead of hiring and supervising in-house AP clerks, you get a trained team that runs the work to your standards.
There is an important distinction the rest of this market blurs. AP automation software is a tool your own staff still has to operate. Outsourced accounts payable is a service that does the work for you. Accountably is the second kind. We are a managed AP service, not a platform you have to buy and migrate to. Our team works inside the accounting and bill-pay software you already use, follows your approval rules, and delivers finished, reviewed work.
That matters because most "AP solutions" you will compare are automation products that still leave the coding, exception handling, and vendor chasing on your desk. We remove the task, not just the keystrokes.
What outsourced AP covers
- Invoice receipt, GL coding, and 3-way matching
- Approval routing and exception handling
- Vendor management and W-9 collection
- Payment scheduling and discount capture
- 1099 tracking and AP aging reporting
Accounts payable shouldn't be the bottleneck
When AP runs on one or two people, every spike, sick day, or resignation turns into a backlog. Senior staff get pulled into approving invoices and chasing vendor issues that should never have reached them – time that should go to advisory, growth, or higher-value work.
Invoice Backlogs
Invoices sit in inboxes for weeks. Missed deadlines mean late fees, lost early-pay discounts, and strained vendor relationships.
Hard to Hire & Keep
AP clerks are tough to hire and often leave in 8–12 months. You lose vendor relationships, workflows, and institutional knowledge each time.
Coding & Control Gaps
Inconsistent expense categorization and weak controls create GL misstatements, duplicate payments, and tax-prep headaches downstream.
High Per-Invoice Cost
$48K–$60K per U.S. AP specialist with benefits, plus supervision and error correction – pushing the cost of each invoice to $12–$22.
Full-Cycle Accounts Payable Execution
Every accounts payable task you can outsource, from invoice receipt to payment scheduling – handled by a trained U.S.-led offshore team inside your systems.

Comprehensive AP dashboards with aging analysis, payment forecasting, and cash flow impact reporting.

Managed AP Service vs. AP Automation Software
Most "AP solutions" you will compare are software you still have to run. Here is the honest difference, and when each one is the right call.
A faster tool
Platforms like Bill.com, Tipalti, or AvidXchange speed up data capture and routing, but your own staff still operate the tool.
- Your team still reviews codes and fixes exceptions
- Someone in-house owns vendor chasing and disputes
- You pay a license whether the work gets done or not
- Best when you have staff capacity and just want speed
The work done for you
A trained U.S.-led team runs the full cycle inside your own software, so the task leaves your desk instead of just moving faster.
- Coding, matching, and exceptions handled for you
- Vendor management and W-9s owned end to end
- Multi-layer review before anything reaches you
- Best when you want capacity, not another login
Most teams run both. The strongest setup is automation software for capture plus a managed team to operate it, code the exceptions, and own vendor relationships. We run AP inside the tools you already license – no migration, no replacing your stack.
Four Stages of Review Before It Reaches Your Desk
Offshore AP does not fail on talent. It fails on trust. So we engineer the review into the work. Every invoice batch, vendor file, and 1099 run passes through four layers before a partner ever sees it, which means what reaches you is review-ready, not raw.
1. Preparer
A trained specialist posts, codes, and matches invoices inside your software on your SOPs.
2. Senior Review
A senior checks coding, three-way matching, and exceptions against your approval rules.
3. Quality Review
Quality control runs duplicate-payment and accuracy checks before anything is queued for payment.
4. Final Review
A final pass confirms the batch is clean and ready, so review-ready work lands on your desk.
Don't trust us. Test us. Proof before your name is on the line is the whole point. The review is the product, not the resume.
What You Keep vs. What We Carry
Outsourced AP should never mean handing over judgment or payment authority. You keep the calls that carry your name. We carry the preparation and the review underneath it.
Authority and final judgment
The decisions that carry your name and your liability stay with you, exactly where you set them.
- Final payment release and approval thresholds
- Sign-off on every payment run
- Vendor relationships and any partner-level call
- Full visibility into the AP queue in your own tools
Preparation and the review under it
The volume work that eats your team's hours, prepared inside your software and put through multi-layer review.
- Invoice posting, GL coding, and three-way matching
- Structured workpapers and documentation
- Vendor master upkeep, W-9 collection, 1099 tracking
- The four-stage review that makes the batch payment-ready
The signature stays yours. We carry the preparation and the review so your team stops doing the volume work, while the judgment that carries your name never leaves your hands.
Built By A CPA Who Has Signed The Return
Accountably was founded and is run by a Washington-licensed CPA with more than seven years inside US firms, from PwC to a real-estate tax practice to a full-service firm, rising from reviewer to manager to advisory.
That matters for AP because the person designing your offshore team has sat the review cycle and felt April. Your specialists are trained to the bar a partner signs against, not to a generic data-entry script. We are accountants who learned staffing, not staffers who learned accounting.
This is staffing, not resume farming. The four-stage review, the SOPs, and the SOC 2 aligned controls all exist as proof that supports the work, so you can grade real output before your name is on the line.
The offer, in plain terms
- Trained offshore AP specialists placed inside your firm in about 3 to 4 weeks
- Start with 1 to 3 and scale seat by seat as trust builds
- Not the right fit in the first 30 days, we replace them free
- On rolloff we shadow and hand over so the AP workflow never takes a hit
Our AP Service-Level Agreements
A managed AP service is only as good as what you can hold it to. These are the metrics we commit to and report on, so payables never drift back into a pile of unposted invoices.
| Metric | What it tracks | Why it matters to you |
|---|---|---|
| Invoice posting time | Receipt to posted in the ledger | Slow posting hides what you owe. We post on a fixed turnaround so the AP balance is always real. |
| On-time payment rate | Payments made by their due date | Protects vendor relationships and early-pay discounts; kills late fees. |
| Posting accuracy | Correct GL code, amount, and vendor | Bad coding distorts the financials and creates month-end cleanup. We hold this high under review. |
| Average days to pay | How long invoices sit before payment | Lets you manage cash deliberately instead of paying too early or too late by accident. |
| Duplicate-payment rate | Paid-twice errors caught vs. missed | Three-way matching and a duplicate check stop the most expensive AP mistake there is. |
Is Accounts Payable Outsourcing Right for You?
It is not the right call for every business. Here is the straight version of what you gain and what you give up.
What you gain
A trained team that posts and pays on a schedule, three-way matching and duplicate checks that catch costly errors, coverage that does not collapse when one person is out, and senior time back from chasing invoices.
What you give up, and how we handle it
Some hands-on control of the day-to-day queue. We offset it by working inside your own AP software on your approval rules, so you keep visibility and final sign-off on every payment run rather than handing it to a black box.
When in-house still makes sense: a low invoice volume that one person handles comfortably, or a business where payables are simple and rarely the bottleneck. The math tips toward outsourcing once invoice volume climbs, approvals span multiple people, or late payments and duplicate-pay errors start showing up in the numbers.
How Much Does Accounts Payable Outsourcing Cost?
Outsourced AP is usually priced per invoice or as a flat monthly fee, scaled to your volume and complexity.
Per Invoice
Typical range for outsourced processing, depending on PO vs. non-PO invoices and approval complexity.
Per Month
Common flat-fee range for small portfolios processing roughly 50–150 invoices a month.
QC Review
Every invoice batch runs through preparer, senior, and quality review before it reaches your U.S. team for final sign-off.
Your exact price depends on monthly invoice volume, the number of entities or clients, payment methods, and how much of the cycle you want us to own. We scope it on a short discovery call and quote a fixed monthly number, so there are no per-keystroke surprises.
In-House vs. Accountably
The average U.S. AP specialist costs $48K–$60K in salary alone. Add benefits, payroll tax, training, supervision, and turnover – you're looking at $65K–$80K fully loaded per head before they even process their first invoice batch. A managed offshore team delivers the same output inside your systems, with multi-layer review and a 24-hour turnaround SLA, so invoices clear on schedule without the coverage gaps a single in-house hire leaves behind.
| Comparison | U.S. In-House Staff | Accountably |
|---|---|---|
| Senior AP Specialist (Annual) | $60,000 – $75,000 | $22,000 – $30,000 |
| Staff AP Clerk (Annual) | $42,000 – $55,000 | $16,000 – $22,000 |
| Time to Productivity | 3–6 months | 2–3 weeks |
| Multi-Entity Experience | Varies | ✓ Standard |
| Multi-Layer QC Built In | ✗ Not included | ✓ 4-tier review |
| Backup Coverage | ✗ No coverage | ✓ Always covered |
| Invoice Processing SLA | No guarantee | ✓ 24-hour turnaround |
| Turnover Risk | High – 8–12 mo avg | ✓ 98.7% retention |
