The most common mistake businesses make when going paperless is digitising a broken process. If your current AP workflow has bottlenecks, approval delays, or data quality problems, automating it will make those problems faster — not better. Before you invest in any technology, spend two to three weeks documenting exactly how invoices flow through your business today: where they arrive, who touches them, how long each step takes, and where they get stuck.

Map the end-to-end process from invoice receipt to payment, noting every manual step, every handoff, and every system involved. Calculate your current cost per invoice (typically $15–$40 for a manual process) and your average processing time (typically 8–12 days). These baseline metrics will help you choose the right technology, set realistic improvement targets, and demonstrate ROI after the transition. The audit also surfaces process improvements that can be made before digitisation — simplifying the process first makes the technology implementation faster and cheaper.

The first step in a paperless AP process is ensuring that invoices arrive in a digital format. For most businesses, this means establishing a dedicated AP email address (such as [email protected]) and communicating it to all suppliers. Suppliers who currently send paper invoices by post should be asked to switch to email; most will comply readily because email is cheaper and faster for them too.

For suppliers who cannot or will not send invoices electronically, a scanning and capture process is needed. This can be as simple as a smartphone scanning app that converts paper invoices to PDF, or as sophisticated as a dedicated document scanner with automatic PDF output. The key requirement is that every invoice, regardless of how it arrives, is converted to a searchable PDF before it enters your AP workflow. Accepting invoices in multiple formats — PDF, image, Word document — creates complexity downstream; standardising on PDF from the outset simplifies everything that follows.

Once invoices are arriving as PDFs, the next step is extracting the structured data from them — vendor name, invoice number, date, line items, totals, tax, and payment terms — so that data can flow into your accounting system without manual keying. This is where AI extraction tools like Pedfs add their primary value: they read the PDF, identify the relevant fields, and output structured data in seconds, regardless of the invoice format or layout.

When evaluating AI extraction tools, the key metrics to assess are accuracy (what percentage of fields are extracted correctly without human correction), supported formats (can it handle scanned PDFs, not just digital ones), integration options (can it push data directly to your accounting system), and pricing model (per-invoice pricing scales with your volume, while flat monthly pricing is better for predictable high volumes). For businesses processing under 200 invoices per month, a tool with per-invoice pricing and a free tier for initial testing is usually the most cost-effective starting point.

A paperless AP process requires a clean, digital vendor master file — a structured database of every supplier your business pays, including their legal name, address, bank account details, payment terms, and tax identification number. If your vendor master currently exists as a spreadsheet, a folder of paper contracts, or scattered across email threads, migrating it to a structured digital format is a prerequisite for effective AP automation.

The migration process involves collecting the required information for every active vendor, verifying it against source documents (contracts, bank confirmation letters), and entering it into your accounting system or AP platform. This is also an excellent opportunity to deactivate vendors you no longer use, consolidate duplicate vendor records, and verify that all bank account details are current and accurate. A clean vendor master file not only enables automation — it also significantly reduces your exposure to vendor impersonation fraud, because every payment is validated against a verified record.

Paper-based invoice approval — printing the invoice, routing it to the approver's desk, waiting for a signature, and filing the signed copy — is one of the biggest sources of delay in a manual AP process. A single invoice can sit on someone's desk for days waiting for approval, and there is no visibility into where it is or when it will be returned. Digital approval workflows replace this with automated routing, email notifications, and a complete audit trail.

A well-designed digital approval workflow routes each invoice to the correct approver based on rules you define — typically by vendor, cost centre, or invoice amount. The approver receives an email notification with a link to review and approve the invoice digitally, without needing to print anything. If they do not respond within a defined timeframe, the workflow automatically escalates to their manager. Every approval action is logged with a timestamp and the approver's identity, creating an audit trail that satisfies both internal controls requirements and external audit requests.

The final step in building a fully paperless AP process is connecting your invoice extraction tool to your accounting system — QuickBooks, Xero, Sage, or whichever platform you use — so that extracted invoice data flows directly into the system without manual re-entry. Our integrations page shows how Pedfs connects to the major accounting platforms, eliminating the last remaining manual step in the process.

Most modern AP automation tools offer native integrations with the major accounting platforms, or API access for custom integrations. When setting up the integration, the key configuration decisions are: how to map vendor names from invoices to vendor records in your accounting system (vendor matching), how to assign GL codes to invoice line items (coding rules), and how to handle exceptions where the extraction confidence is below a defined threshold (exception queues). Getting these configuration decisions right at the outset prevents the most common integration problems and ensures that the data flowing into your accounting system is accurate and complete.

Technology implementation is only half of a successful AP transformation. The other half is change management — ensuring that your team understands the new process, is confident using the new tools, and is motivated to make the transition work. AP staff who feel that automation threatens their jobs are likely to resist the change; those who understand that automation handles the tedious data entry work and frees them for higher-value activities are much more likely to embrace it.

Training should be hands-on and role-specific. Invoice processors need to know how to review and correct AI extraction results, manage exception queues, and handle supplier queries. Approvers need to know how to use the digital approval interface. Finance managers need to know how to access the AP dashboard, run reports, and monitor KPIs. Communicate the timeline, the reasons for the change, and what each person's role will look like after the transition. A clear communication plan that addresses the "what's in it for me" question for each stakeholder group significantly increases adoption rates.

Once your paperless AP process is live, measuring its performance against your pre-transition baseline is essential for demonstrating ROI and identifying further improvement opportunities. The four most important AP KPIs to track are: cost per invoice (total AP department cost divided by invoice volume), invoice processing cycle time (days from invoice receipt to payment approval), straight-through processing rate (percentage of invoices processed without human intervention), and exception rate (percentage of invoices requiring manual correction or escalation).

Benchmark your post-transition performance against your pre-transition baseline after 30, 60, and 90 days. Most businesses see cost per invoice fall by 50–70% and cycle time reduce by 60–80% within the first 90 days of a well-implemented paperless AP process. Share these results with senior management to build support for further investment in AP automation and to make the business case for extending the approach to other finance processes.
