Know what changed before you approve the bill.
InvoiceDrift is a browser-based supplier invoice comparison tool. Upload an invoice and the quote, purchase order, order confirmation, or previous invoice it should match; get line-by-line evidence of price and quantity changes before you approve the bill—without a sales call or accounting integration.
5 private audits free · 2 optional matching improvements · No card
From two documents to a clear answer.
- Upload the evidence. Add one supplier invoice and a quote, PO, order confirmation or previous invoice.
- Compare every line. InvoiceDrift resolves product descriptions, then checks quantities and unit prices using deterministic arithmetic.
- Confirm once. Remember next time. Confirm an unresolved description once and InvoiceDrift remembers the match privately for your business.
Every finding shows both source values. Low-confidence matches are held for review instead of being presented as fact. Potential differences are not allegations of supplier error.

Planned Starter and Trade plans will add larger monthly audit allowances and automatic advanced description matching.
Built for commercially sensitive files.
Every audit starts locally in your browser. If descriptions remain uncertain, optional advanced matching sends only sanitized descriptions—never files, full text, quantities, prices or totals. Confirmed corrections can be remembered privately for your business, while unresolved lines remain excluded from financial totals.
Common questions about InvoiceDrift
What does InvoiceDrift compare?
InvoiceDrift compares a supplier invoice with a quote, purchase order, order confirmation, or previous invoice. It resolves matching line items, then shows quantity and unit-price differences with both source values.
Do I need Xero to use InvoiceDrift?
No. InvoiceDrift works from documents you upload in your browser, so you can run an audit without Xero or another accounting integration.
Is every difference an overcharge?
No. A difference may be legitimate, previously authorised, or caused by an unresolved match. InvoiceDrift presents supporting values for your business to review; it does not accuse a supplier or approve a payment.
Which documents and layouts work best?
Supplier quotes and order confirmations usually provide the strongest price evidence; detailed purchase orders and previous invoices also work. Digital PDFs, TXT, or CSV files with clear description, quantity, unit-price, and line-total rows work best.
