If you are at the point of evaluating your accounts payable (AP) automation, you have probably already read the brochures. You know the headline claims: 80% reduction in processing time, cost per invoice down to a few dollars, your AP team freed up for strategic work.
What you actually want to know is whether any of it is true for a business like yours and what the vendor isn't telling you upfront. Here are the 7 questions we hear most often from CFOs, Finance Directors and AP Managers before they make a decision.
1. What does it actually cost per invoice once automated?
The ATO, in collaboration with Deloitte Access Economics, estimates that processing a PDF invoice manually costs Australian businesses an average of AU$27.67 and a paper invoice AU$30.87.
With automation, that drops to as little as $2.36 per invoice. That is a reduction of more than 90% from the paper baseline and around 85% from the PDF baseline. And based on our client experience, the best-in-class AP teams can now process invoices as low as ~$1 per invoice.
Your actual cost will sit within that range depending on invoice complexity, exception rates and your ERP environment. For a business processing 1,000 invoices a month, even a conservative automated cost of $5 per invoice represents a saving of over $270,000 per year against the ATO's PDF benchmark.
2. Will it integrate with our ERP?
In almost all cases, yes but the depth of integration matters as much as the fact of it.
Most ERPs used by Australian mid-large market businesses (e.g. Odoo, MYOB Acumatica, SAP Business One, NetSuite, Microsoft Dynamics) are supported by established AP automation platforms.
The question worth asking isn't "does it integrate?" but "what does the integration actually do?"
A genuine integration means invoice data flows directly into your ERP without manual re-entry, GL coding is automated against your chart of accounts, approval status is visible inside your ERP and payment records reconcile automatically.
A surface-level integration might just mean CSV exports and manual imports, which reduces some effort but doesn't eliminate the risk of error.
Ask any vendor to walk you through exactly how an invoice moves from receipt to ERP posting in their system, without any manual steps. That conversation will tell you more than any feature list.
3. What happens to our AP staff?
This is the question that often goes unasked in formal evaluations but sits at the front of everyone's mind.
The honest answer is that most businesses processing 500+ invoices per month don't eliminate AP headcount but they redeploy it. Most companies redeploy AP staff to higher-value work rather than eliminating positions.
Exception handling, supplier relationship management, cash flow reporting and month-end analysis are all areas where experienced AP staff add genuine value. This is also where most teams currently have no capacity because data entry consumes most of their day.
The more important long-term question is what happens when invoice volumes grow. Without automation, growth means either hiring more AP staff or processing invoices more slowly. With automation, your existing team absorbs significantly higher volumes without the headcount cost scaling with them.
4. What about our data - where do they go?
This is particularly important for Australian businesses and it is a question that global software vendors sometimes answer less clearly than they should.
Invoice data is commercially sensitive. It contains supplier banking details, payment amounts, pricing information and internal approval structures. For businesses with any compliance obligations, for example listed entities, government departments or contractors, healthcare organisations, the question of where that data is stored and processed is a primary concern.
For us here at Pacific Commerce, we process all client data onshore in Australia and no data is transferred to international servers. The business is ISO27001 certified, which means our information security controls are independently audited to an internationally recognised standard.
For organisations where data sovereignty matters, that distinction is worth asking every vendor about directly and getting in writing.
5. Our invoice formats are inconsistent - can automation handle them?
Between 85% and 95% of standard invoices can be fully automated, even when formats vary between suppliers. Modern AP automation uses a combination of smart OCR, AI-driven data extraction and supplier-specific rules to handle the variation that exists across most supplier bases.
The invoices that require human review are those with genuine exceptions: missing purchase order (PO) references, line-item discrepancies, unusual GST treatment or new suppliers not yet mapped in the system.
A well-configured AP automation platform surfaces those exceptions clearly and routes them to the right person, rather than letting them sit in an inbox.
If you have specific suppliers with particularly non-standard invoice formats, it is worth testing those during the evaluation phase. A credible provider will run a proof-of-concept against your actual invoice sample before you commit.
6. We already use an ERP/software for invoices - why isn't that enough?
That is because most ERP invoice modules are built to store and pay invoices, not to eliminate the cost of processing them. The expensive part of manual AP isn't approving an invoice but everything that happens before that.
Receiving the invoice, extracting the data, keying it into the system, matching it to a PO, coding it to the right GL account, routing it to an approver. Most ERP modules assume that data has already been entered correctly before it reaches them.
AP automation software connects the moment a supplier invoice arrives to the moment it clears your books, without your team touching a spreadsheet or chasing an approver. That is what most ERP modules don't do.
The question to ask then, is: in your current process, how many minutes does an AP staff member spend per invoice before it is posted in your ERP? If the answer is more than a few minutes, your ERP is the destination but not the solution.
7. What should we look for when comparing providers?
Beyond the technical checklist, here are the questions we would encourage you to ask any provider:
- Where is our data stored and processed? If the answer involves offshore servers or third-party data processors in other jurisdictions, understand the implications before you sign.
- What does your support model look like? There is a meaningful difference between a local team you can call during business hours and a global helpdesk operating on a ticket system. When your month-end close depends on AP running correctly, response time matters.
- Is your pricing model fixed or volume-based? A usage-based, pay-per-invoice model means your cost scales down if volumes drop and you are not locked into a fixed licence fee regardless of what you actually use.
- Can you customise approval workflows, GL coding rules and exception handling to match our processes? Rigid SaaS platforms often require you to adapt your processes to their system. For businesses with specific compliance or governance requirements, that can create more problems than it solves.
- Can you show me the integration with our specific ERP, running against invoices like ours? Any credible provider should be willing to demonstrate this before contract.
Businesses that get the most from AP automation are the ones that ask the hard questions upfront and not after go-live. If you have any questions, feel free to reach out and we are more than happy to chat.
