Free invoice audit — connect Xero, get your first findings in minutes

Most businesses lose money on invoices. Are you one of them?

We scan your Xero invoices to detect price increases, duplicate payments, and missed credits — the things your accounting software never flags.

Read-only Xero access. Set up in minutes. No credit card required.

What we scan for

These are the patterns hiding in your invoices

InvoiceSniff looks for three types of issues that add up quietly over time. Even small misses across dozens of invoices can cost thousands a year.

Price increases over time

Same supplier, same item — but the unit price quietly goes up across invoices. A 3% bump here, a 5% bump there. Nobody notices because each invoice looks normal on its own.

We track every product price per supplier and alert you the moment it changes.

Duplicate payments

Same invoice, slightly different reference number. Same supplier, same amount, different date. Xero only catches exact matches — we catch the fuzzy ones too.

We compare invoices across multiple dimensions to find near-duplicates.

Unapplied credits

A supplier issues a credit note for a return or dispute. It sits on your books for months, never applied to a future invoice. Money you're owed, just forgotten.

We surface every credit and refund that hasn't been used.

If you've never checked for these, there's a high chance some exist in your books right now.

Why this usually goes unnoticed

It's not that you're careless. It's that these problems are invisible to normal accounting workflows.

Prices change gradually

A 3% increase on one invoice looks normal. It only becomes visible when you compare it to what you paid 6 months ago — which nobody does manually.

Credits are issued separately

A credit note arrives in a different month from the original invoice. It gets recorded but never applied. Out of sight, out of mind.

Duplicates look legitimate

Two invoices from the same supplier, same amount, but slightly different reference numbers. Both look real. Both get paid.

Ongoing protection

Every new invoice, automatically checked

After the initial audit, InvoiceSniff keeps watching. Every time a new invoice syncs from Xero, we compare it against your price history.

When a supplier raises a price beyond your threshold, you get a clear email showing exactly what changed and by how much.

What Xero shows vs what gets missed

Xero is great at accounting. But it treats every invoice as a standalone event — it never compares prices, never looks back, never connects the dots.

Xero sees:

  • Each invoice in isolation
  • No price comparison across invoices
  • Basic duplicate check (exact match only)
  • Credits listed but not flagged if unused

InvoiceSniff sees:

  • Price changes across every invoice, per product, per supplier
  • AI matches items even when descriptions differ
  • Fuzzy duplicate detection (same invoice, different reference)
  • Surfaces forgotten credits and unapplied refunds

Your first audit is free

Connect your Xero account and we'll scan your invoices for price increases, duplicate payments, and missed credits. Most businesses never check for this — and small issues add up over time.
