How to eliminate invoice disputes before they start
Invoice disputes are one of the most frustrating parts of B2B commerce. They delay payment, consume administrative time, and – perhaps worst of all – they erode trust between buyers and suppliers. The good news? Most disputes are entirely preventable.
Why disputes happen
In our experience, the vast majority of invoice disputes fall into four categories:
- Price discrepancies – the invoice doesn’t match the agreed price
- Quantity mismatches – the invoice says 100, but only 80 were delivered
- Missing information – no PO number, wrong address, missing VAT details
- Duplicate invoices – the same invoice sent twice, sometimes months apart
Notice something? None of these are malicious. They’re all process failures – and process failures can be fixed with better processes.
Lock in prices at the point of order
Price disputes almost always stem from ambiguity at the ordering stage. If the buyer selects products from a catalogue with fixed prices, there’s nothing to argue about later. The invoice matches the order because they’re generated from the same data.
Capture PO numbers upfront
Missing PO numbers are the single most common reason invoices get held up. If your invoicing process captures the PO number at the point of invoice creation – rather than adding it as an afterthought – this entire category of disputes disappears.
Use verified company data
Wrong company names, outdated addresses, and incorrect VAT numbers cause invoices to bounce around organisations for weeks. By verifying company details against official registries (like Companies House or the Swiss Zefix register) at the point of entry, you ensure every invoice is addressed correctly the first time.
Make invoices impossible to lose
When invoices are sent via a shared portal rather than email, both parties can see every invoice, its status, and its full history. There’s no “I never received it” because the system shows exactly when it was created and viewed. This transparency alone eliminates a huge proportion of disputes.
The relationship dividend
Beyond the direct time and cost savings, dispute-free invoicing builds stronger supplier relationships. When suppliers know they’ll be paid promptly and without hassle, they’re more likely to offer better terms, prioritise your orders, and go the extra mile when you need flexibility.
