There is a moment in almost every conversation I have with a CFO when the topic shifts from invoices to something more uncomfortable. It usually starts with a simple question: at what point does your business actually approve its spend? For most companies the honest answer is that approval happens when the invoice arrives. By then the goods have been ordered, the service delivered and the money committed. The approval is a formality, because the only real alternative is a dispute with a supplier.
That is the control gap this article is about. Purchase order matching and purchase order requisitions are often described as efficiency tools, and they are. But for finance leaders their real value sits somewhere else entirely: they move the point of control from after the money is committed to before it is.
The problem with approving spend after the fact
When invoice approval is the first formal checkpoint, three things follow. Unauthorised or off-budget purchases surface weeks after they were made, when the only options are to pay or to argue. Finance discovers its committed costs at invoice time, which makes accruals and cash forecasting a monthly exercise in detective work. And every invoice, even a perfectly correct one, needs someone to check it against an order and a delivery, line by line, before it can be posted.
None of this reflects badly on the accounts team. It is simply what happens when the process starts at the invoice. The fix is to start earlier.
PO matching: let the correct invoices post themselves
With PaperLess Purchase Order Matching, invoice data is captured automatically and, when a purchase order number is detected, the software checks the corresponding PO in Sage, Xero or SAP Business One and compares the amounts. If they match, the invoice is posted and the purchase order is closed, with no human involvement at all. Combined with Company Inbox handling emailed invoices on arrival, this means a matched invoice can travel from a supplier’s outbox to a posted Sage transaction without anyone in your business touching it.
The consequence for the accounts team is that their attention goes exclusively where it is needed: the exceptions. Invoices that exceed the approved PO amount do not slip through and do not block the queue. They are routed for review with the variance clearly identified, so the conversation with the supplier or the budget holder happens straight away, not at month end.
PO requisitions: control before the order even exists
Matching governs what happens when the invoice arrives. PaperLess PO Requisitions governs everything before that. Anyone who needs to buy something raises a requisition, which is routed for approval based on rules you define: by amount, supplier, department, project, nominal code or cost code. Approvers authorise from a browser or the mobile app, and once approved, the purchase order is created directly in Sage, Xero or SAP Business One. Only then does an order reach a supplier.
Two details matter more than they first appear. Requisitions can be raised by people who are not accounting software users, which means departments across the business follow the process without needing Sage licences or training. And the full approval history stays linked to the purchase order, retrievable through a live lookup from within your accounting software, so every order carries its own audit trail: who requested it, who approved it, when, and with what comments.
Why this changes the CFO’s position
Put the two together and the finance function stops being the last to know. Committed spend is visible from the moment a requisition is approved, not when the invoice lands, which transforms the accuracy of accruals and cash forecasting. Spending policies enforce themselves, because an order outside the rules cannot be raised in the first place. Duplicate and inflated invoices lose their easiest route in, since anything that does not match an approved PO is flagged rather than paid.
For businesses that want to go further, the PaperLess Budgeting Module adds real-time tracking of actual and committed costs against budgets by department, project, nominal code or supplier, so overspend is visible before the purchase decision rather than after it. We wrote about the finance leader’s perspective in more depth in why CFOs are turning to PaperLess to streamline PO requisition.
The closed loop, end to end
This is what the complete cycle looks like with PaperLess in place. A requisition is raised and approved under your rules. The purchase order is created in Sage, Xero or SAP Business One and sent to the supplier. The invoice arrives by email, is captured automatically, matched against the PO, and posted with the document attached to the accounting line. Correct invoices flow through untouched; exceptions surface immediately with full context. Every step is logged, every document retrievable in seconds. Our customer case studies show what that looks like across manufacturing, hospitality and services businesses of very different sizes.
As with everything we build, this runs as a Sage certified solution and a certified app on the Xero App Store, and you can read what finance teams make of working with us on Trustpilot.
See it against your own purchase orders
The fastest way to evaluate PO matching and requisitions is not a feature list, it is watching your own documents flow through the system.

We will show you the match, the variance handling and the requisition workflow live, and you can judge the control gap for yourself.
