Invoice Processing

Invoice Processing Manually

In medium and large-sized organisations, invoice processing is a core part of the Accounts Payable function and plays a key role in financial control. Effective invoice management supports accurate cash flow forecasting, giving finance teams clear visibility over upcoming payments and liabilities.

Beyond cash flow, invoice data provides insight into supplier performance, purchasing efficiency, and the health of supply chains. When invoices are processed accurately and on time, businesses benefit from stronger supplier relationships, fewer disputes, and a more reliable, well-controlled AP process.

Manual Invoice Process and Journey

In a manual invoice process, invoices enter the business in a variety of formats, including paper, email attachments, PDFs, or other digital files. Regardless of how the invoice is received, key information must be identified and captured before it can be processed by the Accounts Payable team.

This typically involves extracting basic header details from the invoice, such as:

  • Supplier name and details

  • Invoice date

  • Purchase order number

  • Invoice reference number

  • Net amount

  • VAT amount

  • Total invoice value

In manual workflows, this information is often entered into finance systems by hand, creating delays and increasing the risk of errors before the invoice can move through approval and payment.

How Does the Manual Invoice Process Work?

Invoice data is manually entered into a finance system, spreadsheet, or payment platform before being submitted for approval. In most cases, invoices are checked against purchase orders and goods received notes through two-way or three-way matching to confirm accuracy.

Copies of invoices are then circulated for approval and often scanned or stored electronically for audit purposes. Once approved, invoices may require additional sign-off before being passed back to the Accounts Payable team for payment.

At every stage, manual handling introduces delays and risk. Data entry, document movement, and filing increase the likelihood of errors, lost invoices, and approval bottlenecks.

Approval Delays and Manual Handling Risks

Once an invoice is entered into a finance system, it is typically circulated across the business for matching and approval. This stage introduces some of the most common causes of delay, with invoices being misplaced in in-trays, sent to the wrong approver, overlooked, or held up when key individuals are on leave or unavailable.

As approvals stall, the Accounts Payable team often spends valuable time chasing invoices internally while also responding to supplier queries about payment status. When invoices do return for payment, additional manual checks are required, including supplier details, coding, tax validation, budget updates, and reporting. Each step adds time, increases workload, and raises the risk of errors within the process.

Invoice Processing with Automation

Invoice automation ranges from simple data capture through to fully integrated purchase-to-pay workflows. More advanced solutions can capture invoice data, perform two-way or three-way matching, apply coding rules, manage exceptions, and route invoices through digital approval workflows before posting directly to the finance system for payment.

By automating these steps, businesses remove many of the delays and risks associated with manual invoice processing. Touchpoints are reduced, visibility is improved, and invoices move through the process faster and more consistently, supporting accurate reporting and timely supplier payments.
