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.

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.
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.
Total Cost Cut
Versus the $12–$22 it costs to process the same invoice in-house once salary, software, and review are counted.
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, reviewed, for a fraction of that.
