Accounts payable in a small business usually means one person, a shared inbox and a spreadsheet. Invoices arrive by email, WhatsApp and post. Someone types them into the accounting software, chases approval, pays them, and at month-end ticks them off against the bank statement. Each step is simple. Together they take days every month.
This guide covers what to automate, in what order, and what to keep in human hands.
The five steps of accounts payable
- Collect: get every supplier invoice into one place.
- Read and code: turn the document into a bill, with lines, VAT and accounts.
- Approve: someone confirms the business owes it.
- Book and pay: register the bill and pay it on time.
- Reconcile: match the payment on the bank statement to the invoice.
Step 1: one address for every invoice
Give suppliers one email address for invoices. Most AP tools give each company its own inbox; suppliers keep sending where they send now, and you set a forward. Paper and WhatsApp invoices get photographed into the same place. Done right, nobody hunts for invoices again.
Step 2: let AI read and code, and a person check
This is where the hours go, and the first thing to automate. AI invoice capture reads the supplier, dates, totals and every line with its VAT, and proposes the account for each line from how you booked that supplier before. A person checks what's flagged and clicks once. A simple invoice takes seconds to check instead of minutes to type.
What to look for: line items included in the price, duplicate checks against invoices already booked, and processing in the EU if you're in Europe. See invoice OCR vs AI invoice capture.
Step 3: approvals only where they add value
Don't route every €12 invoice through the owner. Set one approval level for everything, and a second for amounts above a threshold, for example €1,000. Every approval should be logged, so "who approved this?" has an answer. See how approvals work in Invoreg AI.
Step 4: book into the software you already use
The bill should land in your accounting software with the PDF attached and new suppliers created on the way. You shouldn't need to change accounting software to automate AP. For payment, select the bills that are due and generate a payment file (SEPA XML in the euro area) instead of typing transfers one by one.
Step 5: reconcile from the statement, even a PDF
Matching payments to invoices is the other big time sink, especially when one payment covers several invoices. Modern tools read the bank statement, even a PDF or scan with no bank feed, and match each payment to the invoices it settles. You review only the exceptions. See bank reconciliation.
What to keep human
- The final click on anything the AI flagged.
- New supplier set-up and bank details. Changed bank details on an invoice are a classic fraud signal. Confirm them by phone.
- Exceptions: disputes, credit notes and part payments.
