Is Your AP Team Short-Staffed, or Is the Process Creating More Work Than Necessary?
A growing AP backlog does not always mean you need more staff. Manual data entry, repeated corrections and delayed approvals can consume the capacity your team already has.

Before You Hire Another AP Executive, Look at the Process
It is Friday afternoon. The accounts payable queue is growing, approvals are pending, and the finance team is working through another demanding week. Somewhere in the finance director’s inbox is a request to hire another AP executive. The request makes sense. The team is busy, invoices are waiting, and payment deadlines are approaching. But what happens when that new employee joins? If invoices still require manual entry, repeated corrections and several approval follow-ups, the new hire inherits the same inefficiencies. Additional capacity may temporarily reduce the backlog without addressing why it keeps returning. That is the distinction finance leaders need to make. Is invoice volume exceeding the team’s capacity, or is the AP process creating unnecessary work? Improving accounts payable efficiency starts with answering that question.
Accounts Payable Bottlenecks: Where Is the Work Coming From?
An invoice may require only a few minutes of active review but spend days moving between systems, departments and approvers. Much of the workload can accumulate between processing stages. Common sources include: Manual invoice entry: Employees repeatedly capture information already available in digital invoices, increasing effort and the possibility of errors. Recurring exceptions: Missing purchase orders, price discrepancies and incorrect supplier information require investigation and correction. Duplicate handling: Invoices undergo unnecessary rechecks because information is incomplete or responsibility is unclear. Approval delays: AP teams spend time chasing decisions instead of processing invoices. Disconnected systems: Employees manually transfer information between inboxes, approval tools and ERP systems when workflows do not share data effectively. These challenges make accounts payable bottlenecks difficult to resolve through headcount alone. When the same problems recur across hundreds of invoices, the workload becomes a process issue as much as a staffing issue. The first step in AP process optimization is to identify which activities create additional work and which delays occur while invoices wait for the next person or system.
How to Tell a Staffing Problem From a Process Problem
A long invoice queue tells you there is a backlog. It does not tell you why. Before approving additional headcount, establish a baseline using a small set of accounts payable performance metrics. Six measures give you the baseline, Start with manual touches per invoice, which is how many times an employee has to handle an invoice before it can move on. Then look at the exception rate, the percentage of invoices that need investigation or correction before they can proceed. Your rework rate is related, it shows how often an invoice has to be revisited after an error, a correction or a rejection. Next, compare active processing time, how long the team spends actually working on an invoice, with end-to-end cycle time, how long the invoice takes to travel from receipt to approval, posting or payment. A big gap between the two means invoices are waiting, not being worked. Finally, invoices per AP full-time equivalent (FTE) shows how much volume the team handles relative to its available staffing, and it is best read alongside the other five. APQC recommends balancing productivity and cost measures with accuracy and cycle-time indicators instead of relying on one metric. The distinction between active processing time and end-to-end cycle time is especially important. An invoice might require ten minutes of actual work but wait several days for approval. Adding another AP processor will not necessarily shorten that waiting period. Use the patterns to guide your next step: Invoice volume has increased while processing performance remains stable: Assess whether sustained growth justifies additional capacity. Manual touches and corrections are high: Investigate data quality, validation rules and recurring exceptions. Approval waiting times are long: Review ownership, escalation procedures and backup approvers. The workflow is efficient, but the team remains overloaded: Reassess staffing levels, workload distribution and future demand. These indicators are a diagnostic framework, not universal hiring rules. Invoice complexity, regulatory requirements, business growth and payment obligations must also inform the decision.
Ardent Partners’ State of ePayables 2025 research reports an average invoice processing cost of $9.84, an average processing time of 8.2 days, and an average invoice exception rate of 18.4%. The research involved 204 accounts payable professionals and their organizations. These are industry averages, not targets every organization should adopt. Processing costs and cycle times vary with invoice complexity, controls, technology and operating models. The exception rate is particularly relevant to the staffing question. Every invoice requiring additional investigation can generate more work: contacting a supplier, correcting data, resolving a purchase order discrepancy or obtaining clarification from an approver. APQC’s accounts payable benchmarks similarly emphasize cost per invoice, first-time error-free disbursements and the time between invoice receipt and payment. For finance leaders, the lesson is straightforward, measure how much effort each invoice requires, not just how many invoices the team processes. A higher invoice count does not necessarily indicate better productivity if errors, rework and delays are increasing alongside it.
AP Process Optimization: What Should You Fix Before Hiring?
Effective accounts payable process optimization begins by separating necessary financial controls from avoidable administrative work. Matching requirements, segregation of duties and payment approvals protect the organization. Duplicate data entry and repeated checks that add no control value consume capacity without necessarily improving accuracy. Focus on four priorities: Resolve recurring exceptions. Identify suppliers, invoice types and data issues responsible for repeated discrepancies. Address the underlying cause rather than correcting each invoice individually. Reduce unnecessary handoffs. Review each processing stage and remove duplicate activities that do not contribute to accuracy, compliance or approval. Clarify approval ownership. Establish responsible approvers, backups and escalation procedures to prevent invoices from sitting unattended. Improve operational visibility. Track invoice status, exception trends and approval delays so teams can intervene before backlogs grow. The objective is not to eliminate human involvement. It is to ensure employees spend their time on decisions and controls that genuinely require their attention. Once these changes are in place, measure the impact against the original baseline. If manual effort, rework and waiting time decrease, the team may be able to absorb more volume without increasing headcount. If the workload still exceeds available capacity, additional staffing may be justified.
Finance Process Automation: When Does It Improve AP Productivity?
Once workflows are clearly defined, finance process automation can reduce repetitive work across invoice capture, validation, matching, approval routing and ERP posting. However, automating invoice entry alone will not resolve missing purchase orders, inconsistent supplier records or unclear approval responsibilities. The technology may process the initial information faster while the invoice remains stuck at a later stage. This is why AP automation and AP optimization solve different problems. Optimization improves how work moves through the organization. Automation reduces the manual effort required to complete suitable activities. The strongest approach combines both, simplify the workflow, automate repeatable tasks and retain human oversight for exceptions requiring judgement. After implementation, track manual touches, exception rates, approval delays and end-to-end cycle time. These measures help determine whether automation is genuinely improving AP productivity rather than simply moving the bottleneck elsewhere.

How can finance teams improve accounts payable efficiency without hiring?
Reduce manual invoice entry, recurring exceptions, duplicate handling and unnecessary approval delays. Measure processing effort and cycle time to identify improvements before increasing headcount.
How do you identify accounts payable bottlenecks?
Track invoices from receipt to posting or payment. Review manual touches, exception rates, approval waiting times and repeated corrections to identify where work accumulates.
What are the most important AP performance metrics?
Key metrics include cost per invoice, invoices processed per FTE, exception rate, first-time error-free disbursements, active processing time and end-to-end invoice cycle time. Together, they provide a more balanced view of productivity, accuracy and efficiency.
Why do invoice processing delays continue after AP automation?
Automation may accelerate data capture without resolving inaccurate supplier information, missing purchase orders, complex exceptions or unclear approval ownership. Reviewing each stage helps identify where the process continues to slow down.
When should a company hire more AP staff instead of automating?
Additional staff may be necessary when invoice volume has increased sustainably, regulatory requirements create additional work, or an optimized process still exceeds available capacity. Compare the workload with available capacity before deciding whether hiring, process redesign or automation is the most appropriate response.
