FOR MULTI-SUPPLIER RETAILERS
Know what changed.
Keep your price files local.
Compare supplier costs by SKU, account for pack sizes, and review gross margin impact.
01 Choose your price files
CSV / XLSX · up to 1,000 data rows per file · 5 MB each
02 Confirm the comparison basis
For ex-tax gross margins, all costs and selling prices must exclude tax. No currency, tax or unit conversion is performed.
03 Review the changes
Margins hold the current selling price constant. “pp” means percentage points. No total profit or sales-volume forecast is inferred.

Privacy you can check
Local processing
The comparison runs on your device. This build has no upload API, analytics, cloud model calls or browser storage. Clearing the session removes file references from the app; it is not a secure memory wipe.
What the website receives
Cloudflare hosts this website and receives normal page requests, including connection information such as your IP address. Your selected price files are processed locally. The page blocks application network connections after loading. You still need to trust the delivered code and your device.
Separate billing and support
A future checkout will handle billing details separately. For support, share a fictional or carefully sanitized sample only. Never email raw supplier files. Device security, browser extensions and company policy still matter.
