AP automation means using software to handle the repetitive parts of paying suppliers: capturing invoice data, matching it to purchase orders, coding it to the right accounts, routing it for approval and preparing the payment run. Done well, a person only looks at the invoices that need judgement. The rest move through on their own.
This guide walks through the AP process, where the time goes, what to automate first and whether to build or buy. Our finance and accounting automations cover each step.
What does the accounts payable process look like?
Most businesses follow the same path, whatever software they use:
- An invoice arrives, usually by email as a PDF, sometimes on paper or through a portal.
- Someone keys the details into the accounting system.
- The invoice is checked against a purchase order and goods received, or against an agreed price.
- It is coded to an expense account, cost centre and VAT code.
- The right person approves it.
- It joins a payment run and is paid on the due date.
- The payment is reconciled in the bank.
Where does the time go?
Not where people assume. Paying is quick. The time goes on typing data from PDFs, chasing approvers, resolving mismatches and hunting for the invoice that “was sent last week”. Exceptions cost far more than clean invoices, so a good system is judged by how it handles the awkward ones: missing PO numbers, price differences, split deliveries, credit notes and invoices in another language.
What to automate in AP
Take these in roughly this order, because each feeds the next.
Capture. Reading supplier, number, dates, lines, VAT and totals from the document. See vendor invoice data capture and OCR extraction. Modern AI extraction copes with varied layouts better than the template-based OCR of a few years ago, but you still need validation rules and a check on low-confidence fields.
Matching. Comparing the invoice to the purchase order and receipt. See invoice to PO matching. Within an agreed tolerance it passes automatically. Outside it, it goes to a person with the difference highlighted.
Coding. Suggesting the expense account and VAT treatment from supplier history. See invoice coding to GL accounts. A human should confirm new suppliers and unusual lines.
Approval. Routing to the right person by amount, department or supplier, with reminders. See invoice approval routing.
Duplicate detection. Catching the same invoice sent twice, or resubmitted with a changed reference. See duplicate invoice detection. Duplicate payments are one of the more expensive and avoidable AP errors.
Payment run. Grouping approved invoices by due date and terms. See payment run batching and preparation. Automate the preparation and keep a person on the final release.
Where AI helps, and where it should not
AI reads documents, suggests coding, flags unusual amounts and writes a plain summary of why an invoice is on hold. It should not approve payments, change supplier bank details or release money without a person in the loop. Bank detail changes in particular are a classic fraud route, so always verify them through a separate channel.
Invoice management systems: build vs buy
An invoice management system or AP automation product is a reasonable buy when your process is standard and volumes are high. You get a maintained product, support and a roadmap. The cost is a subscription, a workflow that follows the vendor’s design and sometimes limited fit with a local accounting system.
Custom automation suits smaller volumes, unusual rules or a stack that off-the-shelf products do not fit well. You connect capture, matching and approval to the accounting software you already use, and pay once for what you need. The trade-off is that someone must look after it.
When comparing solutions, rather than hunting for a single “best accounts payable automation software”, write down your own criteria:
- Does it post to your accounting system, or only export a file?
- How does it handle VAT and foreign-language invoices?
- What does it do with low-confidence extractions?
- Is there an audit trail of who approved what?
- What are the costs per user and per document at your volume?
AP automation for Maltese businesses
In Malta the accounting systems you meet most often include Xero, Sage 50, Odoo and Microsoft Dynamics 365 Business Central. Each can sit at the end of an automated AP flow, and the right connection method differs. Check what your version supports.
We have dedicated pages for two: Odoo vendor bill processing with AI and Business Central accounts payable automation. For the wider picture, see our guide to automating Xero, Sage and Shireburn workflows in Malta and the note on e-invoicing and Peppol in Malta. Confirm VAT treatment and record-keeping rules with your accountant.
Frequently asked questions
What is AP automation?
It is the use of software, and increasingly AI, to handle invoice capture, matching, coding, approval and payment preparation in accounts payable. People deal with exceptions and final authorisation.
What should I automate first in accounts payable?
Start with invoice data capture, then PO matching, because they remove the most manual keying. Add approval routing and duplicate detection next.
How long does it take to set up AP automation?
A single step such as capture or duplicate detection can be live quickly. A full flow across capture, matching, approval and posting takes longer, mostly because of exceptions and testing. We scope this before starting.
Is AP automation accurate enough to trust?
For clean, standard invoices, usually yes, with validation rules. Keep human review for low-confidence fields, new suppliers and large amounts.
Where Automata fits
We build AP automations step by step or as a full flow, connected to your accounting system. Start with the finance and accounting automations, or look at invoice to PO matching and vendor invoice capture if those are your pain points. Single workflows start from €99, and complex multi-system builds from €799.
