Margin Guard · Price Creep

Your suppliers changed their prices. Did your margins notice?

Upload three recent supplier invoices. We check what moved, flag invoice-visible surcharges and duplicates, and show the estimated annual impact where the evidence supports it.

Check 3 invoices free

UK pounds only (GBP). This free check only works with supplier invoices in British pounds. Do not upload euro (€) or other-currency invoices — the system will reject them. If your invoices are in euros (for example Tenerife), do not use this form. Email info@vipfish.ai instead, or ask for a Signal Audit invoice (bank transfer).

Best results: three invoices from the same supplier, or invoices containing items you buy repeatedly.

PDF, JPG or PNG. Exactly 3 files. Images are compressed in your browser before sending. Keep each PDF under 1.25 MB.

Data boundary: VIPFish does not intentionally save the uploaded invoice files in this v1 flow. Files are sent to our processing provider for one-time extraction and the response is analysed in memory. Platform/provider security and operational logs may apply. The public result contains no hidden price or sales claim. Privacy policy.
