Hire an AP clerk when the job is mostly relationships, physical office work, or daily judgment. Choose accounts payable outsourcing when invoices pile up faster than an employee can check, match, and enter them. When invoice volume is low, use a part-time employee or make AP part of a broader office role. Many companies use a middle path. They hand off repetitive checking while their own people approve spending, verify sensitive changes, and release every payment.
What an AP clerk really costs
Salary is only the starting point. The BLS Occupational Outlook Handbook (2026) reports a median annual wage of $50,670, or $24.36 per hour, for bookkeeping, accounting, and auditing clerks in May 2025. The lowest 10 percent earned less than $36,000. The highest 10 percent earned more than $74,550.
Employers also pay for benefits, payroll taxes, and paid leave. For private industry office and administrative support jobs, wages and salaries were 68.7 percent of total compensation, according to BLS Employer Costs for Employee Compensation (2026). Benefits were 31.3 percent. Total compensation averaged $36.73 per hour, including $25.22 in wages and $11.51 in benefits.
Applied to the BLS median wage, that average benefits share puts estimated employer cost at roughly $74,000 a year. This is an estimate based on the BLS 2026 average for office and administrative support jobs, not a quote for a particular employee. Equipment, management time, recruiting, and vacant-seat coverage may add further costs.
The vacancy also has an operating cost. SHRM Recruiting Benchmarking (2025/2026) reports a median time to fill of 39 calendar days for nonexecutive positions. That leaves the invoice backlog growing for roughly five to six weeks while the seat is open.
The job is checking plus judgment
Accounts payable software already captures bills and supports payment well. The continuing work sits between the invoice, purchase record, receipt, supplier statement, ledger, inbox, and approval.
Much of that work follows defined checks:
- Read invoices received by email, PDF, or scan into usable fields.
- Match each invoice to its purchase order, two-way for services and three-way for goods with the receipt, within tolerance.
- Stop duplicate and near-duplicate invoices before they reach the payment queue.
- Reconcile each supplier statement against the ledger in both directions.
- Answer payment-status questions from the ledger.
- Prepare the month-end AP aging, unmatched items, received-not-billed accruals, and the 1099 list for the year.
The second direction in statement reconciliation matters. A supplier may list an invoice that never reached your books. The supplier believes it is due, while nobody inside your company can see it.
Exceptions require judgment. A useful exception queue gives the decision-maker the reason for the mismatch, the relevant figures, and the difference. The person can decide without reconstructing the problem. Approval should remain tied to the exact figures reviewed. A corrected invoice therefore needs fresh approval.
The average cost to process an invoice was $9.84, and average processing time was 8.2 days, according to Ardent Partners’ State of ePayables (2025). The average exception rate was 18.4 percent, or roughly one invoice in five. Routine checking can be handed off. Exceptions still need someone who understands the business.
When hiring is the right call
A direct hire is often the better answer when invoice volume is low and the employee will spend much of the week on other office work. Reception, incoming mail, filing, deposit preparation, and physical records all benefit from somebody on site.
Hiring also makes sense when suppliers expect regular phone contact with a familiar employee. The same applies when the company relies heavily on paper checks, mailed documents, or frequent face-to-face questions.
Processes that change every week may need an employee close to the people making those changes. A new operation can require constant judgment before repeatable rules exist.
If there are few invoices, the books are current, and the controller is not buried in clerical work, you may not need outside help. A part-time employee or a broader office role may fit better. An Office Work Review can help separate work that should stay in-house from work that can be handed off.
When handing off the checking makes more sense
Accounts payable outsourcing becomes practical when the vacancy has stayed open while invoices continue arriving. It can provide coverage without waiting through the full recruiting cycle.
It also fits when:
- Month-end repeatedly turns into a catch-up exercise.
- Duplicate invoices reach the payment queue.
- Supplier statements reveal bills missing from the ledger.
- The controller spends hours entering routine bills.
- Invoices wait because matching evidence is scattered.
- Payment-status questions interrupt higher-value work.
This does not require giving an outside team control of the whole function. A narrower service can read invoices, perform matching, reconcile statements, prepare drafts, and present exceptions. Your employees retain the decisions.
That boundary is useful when there is plenty of work but not enough for a full-time seat. It also gives an existing AP employee more time for supplier issues and internal follow-up.
What should never leave your hands
Your company should always control the release of money. An outside team can prepare a payment run with due dates, terms, and available discounts. A person inside the company should release it through the company’s own bank.
Supplier bank-detail changes also require internal verification. Freeze any changed account number. A person should call the supplier using a known number and confirm the request. Never apply new payment instructions solely from an email.
The AFP Payments Fraud and Control Survey (2026) found that 76 percent of US organizations experienced attempted or actual payments fraud in 2025. Business email compromise affected 74 percent, and fraudsters commonly impersonated vendors or executives to request payment-instruction changes. The survey covers larger organizations, but a fake request to change a supplier’s bank details follows the same pattern at a small company.
Your people should also judge whether spending is legitimate. That includes a new supplier, an invoice without an order, or a charge nobody recognizes. Coding can be proposed from the company’s own history, but a person should approve the choice.
How accounts payable outsourcing is priced
Providers commonly use several pricing models.
Bookkeeping firms may include AP in a monthly bookkeeping plan or sell it as an add-on. Bookkeeper360 pricing, accessed in 2026, lists bookkeeping starting at $399 per month and a Back-Office add-on that includes AR and AP starting at $150 per month.
Full outsourced accounting departments may place AP inside a broader monthly tier. AccountingDepartment.com pricing, accessed in 2026 prices the whole accounting function in tiers, from up to $1,500 a month to $7,500 a month and more, with no separate AP price published.
Offshore staffing firms often charge by the hour for a dedicated remote clerk. This resembles hiring capacity through a provider. Management responsibility and minimum commitments vary.
Per-invoice pricing also exists, but very few firms publish a usable price list. Invoice complexity matters. A clean recurring bill takes less work than an invoice requiring purchase-order matching, receipt research, or follow-up.
The middle path is to hand off defined checking while keeping approvals and payment release in-house. A sensible first step is a fixed-scope test on your own records before making a longer commitment. The AP Desk uses a ten-business-day pilot with agreed acceptance tests. Work starts read-only, moves to drafts, and remains inside your existing accounts.
Frequently asked questions
Is outsourcing accounts payable cheaper than hiring a clerk?
It depends on invoice volume, exception rates, and how much of the employee’s week AP would occupy. Compare provider cost with the full employer cost, not salary alone. Using the average BLS 2026 benefits share, the BLS median clerk wage implies roughly $74,000 in annual employer cost.
Can outsourced AP work inside QuickBooks Online or Xero?
Yes. The work can be completed inside your own account, with bills written as drafts before approval. The same approach can work with NetSuite, Bill.com, Gmail, and Outlook. Access should begin at the lowest level needed for the test.
What should never be outsourced in AP?
Keep payment release, supplier bank-detail verification, spending legitimacy, and final coding approval with trusted people inside the company. Outside support should prepare evidence and drafts, not make those decisions.
How quickly can an AP outsourcing pilot start?
An AP Desk pilot runs for ten business days after access is confirmed. Acceptance tests are agreed on day one. The first stage is read-only, followed by draft work that your team can inspect.
