Accounts Payable Automation for Australian Businesses on Xero and MYOB

It means software does the repetitive parts of paying suppliers: collecting invoices, reading the details, checking them, entering them as bills in your accounting system, matching them to purchase orders and sending them to the right person to approve. People still decide what gets approved and paid. The goal is fewer typed-in bills, fewer mistakes, and a clear record of who approved what.

Start with where invoices arrive, usually one shared inbox. Then add, in order: reading each invoice and pulling out supplier, ABN, date, amounts and GST; checking it is a valid tax invoice and not a duplicate; coding it to the right account; matching it to a purchase order if you use them; routing it for approval by amount or cost centre; and creating the bill in Xero or MYOB ready for your normal payment run.

It is the set of rules that decides who must approve a supplier invoice before it is paid. A typical small business version: under a set amount, the manager who ordered it approves; above it, a director also approves; anything without a purchase order goes to finance first. Automating it means the invoice goes to the right person by itself, with reminders, and the approval is recorded against the bill.

Three-way matching compares three documents before a bill is paid: the purchase order (what you ordered and at what price), the receipt or delivery record (what actually arrived), and the supplier invoice (what you are being charged). If quantities and prices agree within your tolerance, the bill can go through. If not, it is flagged for a person. Two-way matching skips the delivery check.

Not the way we build it. AI takes the typing and the first round of checks: reading invoices, spotting duplicates, suggesting account codes and matching purchase orders. Your bookkeeper or finance team still owns supplier relationships, approvals, queries, payment runs and month-end. In practice they spend less time keying bills and more time on the exceptions and cash flow decisions that need judgement.

It depends on your size and system. Small businesses on Xero often start with Xero’s own bill capture, Hubdoc, and an approval app from the Xero App Store. MYOB users can use MYOB’s supplier invoice feeds and In Tray. Growing businesses often add dedicated AP software such as Lightyear. A custom AI agent suits you when your rules, suppliers or systems do not fit any of those well.

Partly. Xero can repeat regular invoices and bills, and Xero’s own guide to automating accounts payable points to Hubdoc for capturing supplier bills and to App Store apps for approvals and purchase order matching. What Xero does not do on its own is apply your specific checking, coding and approval rules across every supplier. That is where an approval app or a custom agent comes in.

Yes. Xero’s Accounting API lets approved software create purchase bills, update draft or submitted bills, attach the invoice file and add notes. An AI agent uses that to put checked bills into Xero for you. For a build used by one business, Xero offers Custom Connections, available to Australian organisations as an extra monthly subscription that you buy and authorise in your own Xero account.

Yes. MYOB says its Business API works with AccountRight, new Essentials and MYOB Business files. It can create purchase bills in all four layouts (item, service, professional and miscellaneous) and read purchase orders, including whether an order has been converted to a bill. We confirm your exact MYOB product and setup on the first call, because some setups need extra steps.

It can process most of the paperwork. Current AI models read invoices in almost any layout, pull out supplier, ABN, line items, GST and totals, and suggest account codes from your past bills. It should not make payment decisions on its own. We build it so the AI prepares and checks, your rules decide where each bill goes, and a person approves before money moves.

Not safely on its own. The public ChatGPT app is not connected to your ledger, does not know your account codes or approval rules, and pasting supplier invoices into it sends business data to a tool outside your control. The same kind of model can do useful bookkeeping work inside a proper system, with business data terms, your chart of accounts, audit logs and a person checking the output.

Three main ones. AI can read a figure wrongly or code a bill to the wrong account with confidence, so checks and human review matter. It needs clean inputs: a messy chart of accounts produces messy suggestions. And data may be processed by providers overseas, which brings privacy obligations. We design around all three with validation rules, a review queue, and named providers you approve.

On clear PDF invoices it is very good; on poor phone photos, handwritten dockets and long multi-page statements it is weaker. We do not quote a single accuracy figure because it depends on your suppliers. Instead we replay a sample of your real past invoices through the agent before launch, measure how often each field is right, and set the agent to flag low-confidence reads for a person.

The ATO lists 7 details for taxable sales under $1,000: that it is intended to be a tax invoice, the seller’s identity, the seller’s ABN, the date issued, a brief description including quantity and price, the GST amount (or a statement that the total includes GST), and the extent each sale is taxable. Tax invoices for $1,000 or more must also show the buyer’s identity or ABN.

For purchases over $82.50 including GST, no. The ATO says you must have a tax invoice to claim the GST credit, an invoice with incorrect or incomplete information is not a valid tax invoice, and you cannot claim the credit until you hold one. That is why our agent checks each invoice for the required details and flags incomplete ones so you can ask the supplier for a correct copy.

Peppol is the network Australia has adopted for eInvoicing, where invoices go straight from the supplier’s software to the buyer’s. The ATO says over 400,000 Australian businesses are on it. It removes the reading step for suppliers who use it, but many suppliers still send PDFs. You still need checking, coding, matching and approvals. A good AP setup handles eInvoices and PDFs through the same rules.

ATO: about eInvoicing ↗

The ATO says you need to keep most business records for 5 years, stored so they cannot be changed or damaged. For AP that means the original invoice file, not just the figures typed into Xero or MYOB. Our builds attach the original PDF to each bill and keep a log of every check and approval, so the record and the decision trail sit together.

Scamwatch warns that scammers send invoices with new payee information to redirect real payments, and advises calling the business on a number you found independently. We build that into the process. Any change to a supplier’s bank details, a new supplier, or an invoice from a look-alike email address is held and sent to a named person to verify by phone before anything is approved.

Off-the-shelf AP software is usually a monthly subscription, often priced by invoice volume or users, and published on each vendor’s site. A custom AI agent is a one-off build plus AI usage and support. What moves our scope: how many suppliers and invoice types, whether you use purchase orders, how many approval levels, and which systems it connects to. Our AI cost guide lists Australian market ranges.

A focused first version, reading invoices from one inbox, checking them, and creating draft bills in Xero or MYOB for review, usually takes a few weeks from the first workshop. Purchase order matching, multi-level approvals and more entities add time. It runs in review mode first, where every bill waits for a person, so you see real results on live invoices before you let it do more.

No. We deliberately stop at the approved bill. Payments stay in your normal process, whether that is a batch payment file from Xero, MYOB’s payment tools or your bank portal, with your usual people authorising them. Keeping payment release with a person is one of the simplest controls against fraud and mistakes, and it keeps your bank’s own approval rules in charge.

Yes, and they should be. We work with your bookkeeper or accountant to set the account codes, tax codes, tracking categories and approval rules, and they review the exceptions queue. Many find the work shifts from data entry to reviewing and advising. If your accountant looks after several clients, the same approach can be set up per client in their own Xero or MYOB file.

The invoice files and bills live in your Xero or MYOB file and your own email. The AI model that reads each invoice is run by a provider we choose with you, on business terms that stop your data being used to train its models. Invoices from sole traders can contain personal information, and APP 8 applies if it goes overseas, so we document every provider and where it processes data.

Yes. The workflows, prompts, validation rules, integration code and documentation are yours. You hold the accounts with Xero or MYOB, the email system and the AI provider, and pay them directly with no markup through us. For single-business Xero builds, the Custom Connection sits in your own organisation. If you change bookkeepers or bring the work in-house, the agent keeps running and you keep everything.
