Accounts payable teams are under constant pressure to do more with less.
Finance leaders are expected to process invoices faster, reduce costs, improve supplier relationships, and maintain accurate financial controls. Yet many AP teams still rely on manual processes that slow everything down.
A benchmark report from the Institute of Finance & Management (IOFM) highlighted a common issue across nearly 400 accounts payable departments: efficiency remains the biggest challenge.
The report examined how AP teams measure performance and where improvements are needed. Common performance indicators included:
- Suppliers paid on time
- Cost per invoice
- Invoices processed per full-time employee (FTE)
- Staff-to-manager ratios
These metrics help finance teams understand how efficiently their AP function operates compared to similar organisations.
The findings also showed that AP process improvement and automation were among the highest priorities for finance leaders.
Why Accounts Payable Efficiency Matters
Poor AP efficiency creates problems across the business.
When invoice processing is slow or approvals are delayed, suppliers are paid late. Teams spend more time chasing paperwork. Errors increase. Reporting becomes unreliable.
Many of these issues begin before the invoice even reaches the finance team.
Common upstream problems include:
- Missing purchase orders
- Late invoice submissions
- Pricing discrepancies
- Missing receipts
- Unclear approval trails
- Invoice mismatches
Without structured purchasing controls, accounts payable teams are forced into reactive firefighting.
Improving the wider purchase-to-pay process can reduce these problems significantly.
Common Causes of AP Inefficiency
Manual AP environments often depend on:
- Email-based approvals
- Paper invoices
- Spreadsheet tracking
- Manual data entry
- Disconnected systems
These processes create bottlenecks that waste time and increase risk.
For example:
| Challenge | Business Impact |
|---|---|
| Manual invoice approvals | Delayed supplier payments |
| Missing purchase orders | Invoice disputes |
| Poor visibility of spend | Budget overruns |
| Paper-based processes | Lost documents and slow audits |
| Lack of reporting | Difficulty benchmarking performance |
The good news is that many of these problems can be solved quickly with the right AP process improvement strategy.
3 Steps to Improve Accounts Payable Efficiency
1. Map Your Current AP Processes
Start by documenting your existing invoice approval workflows.
Look beyond invoice processing and examine the entire purchasing journey, including:
- Supplier selection
- Purchase requisitions
- Purchase order approvals
- Goods receipts
- Invoice matching
- Payment approvals
Identify where delays occur.
Ask questions such as:
- Where are invoices waiting too long?
- Which approvals cause bottlenecks?
- How often are invoices disputed?
- Which tasks are still manual?
This exercise helps uncover opportunities to streamline workflows and reduce unnecessary admin.
2. Implement Cloud-Based Purchase Approval Software
One of the fastest ways to improve accounts payable efficiency is to automate the purchase-to-pay process.
Cloud-based AP automation platforms like Zahara help finance teams:
- Automate purchase approvals
- Digitise invoice processing
- Capture invoices electronically
- Match invoices against purchase orders
- Track budgets in real time
- Create approval audit trails
- Reduce paper-based processes
Using a cloud-based system also gives finance teams access to accurate performance data.
This allows businesses to measure:
- Invoice processing times
- Approval turnaround
- Supplier payment performance
- AP workload by employee
- Spend visibility across departments
With automation in place, teams spend less time on admin and more time on financial control and strategic work.

3. Monitor, Improve and Benchmark Performance
AP process improvement is not a one-off project.
The most successful finance teams continuously monitor performance and look for ways to improve.
The IOFM benchmark report recommends tracking metrics such as:
- Percentage of suppliers paid on time
- Cost per invoice
- Invoices processed per FTE
- Staff-to-manager ratio
Benchmarking these figures against similar organisations helps identify gaps and opportunities.
With AP automation software like Zahara, these insights are available through real-time reporting dashboards.
This makes it easier to:
- Identify inefficiencies
- Improve approval workflows
- Reduce invoice processing costs
- Strengthen financial controls
- Support business growth
How AP Automation Supports Process Improvement
Modern AP automation software does more than process invoices.
It creates structure across the entire purchasing process.
Benefits include:
- Faster invoice approvals
- Reduced manual data entry
- Improved audit compliance
- Better supplier relationships
- More accurate budget tracking
- Increased visibility of company spend
Finance teams also gain greater control over purchasing before money is spent.
This proactive approach reduces invoice disputes and improves cash flow management.
For businesses looking to improve <a href=”https://www.zaharasoftware.com/purchase-order-software/”>purchase order software</a> workflows alongside AP automation, integrated purchase-to-pay systems can deliver significant operational gains.
The Link Between Purchasing and AP Efficiency
Many AP issues originate in procurement.
If purchases are not approved correctly at the start of the process, problems appear later when invoices arrive.
For example:
- No approved PO can delay invoice matching
- Incorrect pricing causes disputes
- Missing receipts create approval delays
- Unauthorised spending increases risk
Improving purchasing controls helps accounts payable teams work more efficiently.
This is why many organisations invest in combined <a href=”https://www.zaharasoftware.com/purchase-order-management/”>purchase order management</a> and AP automation solutions.
