Choose two lists
Load previous and new CSV files from one supplier. Match your product ID and price columns.
FOR MULTI-BRAND RETAILERS
See what changed between two price lists—and which products need a closer look before you update your store.
Free. No signup. Supplier files stay in your browser.
THE WORKFLOW
Load previous and new CSV files from one supplier. Match your product ID and price columns.
Find increases, decreases, new and missing records. Check margin impact where current selling prices are available.
Export the full comparison for your review. Nothing changes in your store, and uncertain rows are flagged instead of guessed.
BUILT FOR A SPECIFIC MOMENT
If that happens every month, and you're still checking rows by hand, we'd like to learn about your process.
You resell products from multiple suppliers.
You review price updates at least monthly.
Your files have stable product IDs and comparable prices.
Your current tools still leave manual review work.
HELP SHAPE THE NEXT VERSION
We're looking for independent retailers to try the tool and walk us through their last supplier price update. Shopify retailers are our initial focus; no Shopify connection is needed.
Testing the current tool is free. Participation doesn't commit you to a subscription.
Ask about the pilot →Opens your email app; nothing is sent automatically. Or email suppliereviewhelp@outlook.com.
Please don't email confidential supplier files. Start with a description of your workflow.
BEFORE YOU TRY IT
No. The comparison tool reads files in this browser tab and doesn't upload them or save them to browser storage. Closing or reloading clears the loaded comparison. Exported files remain on your device. The website host may receive standard request metadata when serving the page. See data handling.
Export each worksheet as CSV UTF-8 first. The pilot supports CSV files up to 5 MB and 10,000 rows each, with unique headers. Native XLSX, PDF and scanned documents aren't supported.
Gross margin is (selling price − purchase cost) ÷ selling price. Both before and after use the current selling price mapped from the previous file. It excludes shipping, taxes, discounts, payment fees and other expenses. It's not markup or net profit. Missing selling prices are not estimated.
Use price-only mode. Margin checks require your actual purchase costs and selling prices. Both lists must use USD and comparable units or packs; the tool doesn't convert currencies or pack sizes.
No. It produces a review report, not a ready-to-import Shopify file. There are no integrations or automated price changes. Product IDs are matched exactly after trimming surrounding spaces; duplicates and invalid values need your review.
Not yet. The current tool is free. We're testing demand for a $39/month saved workspace before building accounts or billing. Any future paid offer will describe the actual available features and terms before you choose to buy.
