Who it fits
It fits a store or wholesaler whose supplier publishes a price list as a CSV file at a public https address, with exact, unique SKUs. If your supplier only sends prices by email or as a PDF, this version will not work for you yet.
How it works
- Add the file address and the names of its SKU and price columns.
- The first check saves that file as your starting point.
- Each day we compare the new file with the last good one.
- When something changed, you get a short email with the largest changes first.
What a report looks like
Example with made-up SKUs and prices.
| SKU | Before | After | Change |
|---|---|---|---|
| TSHIRT-BLK-M | 8.40 | 11.20 | +33.33% unusual |
| MUG-WHT-11 | 3.10 | 3.40 | +9.68% |
| CAP-NVY | 6.00 | 5.75 | -4.17% |
Built not to raise false alarms
- Broken files are refused. If more than half of the SKUs vanish, or more than 80% of the prices move at once, you get a warning and your starting point stays on the last good file.
- No guessing. SKUs match exactly, and a SKU that appears twice is reported and left out.
- Quiet by default. No change means no email. The same broken file warns you once.
- You hear about outages. After three failed checks in a row you get one alert.
What it does not do
It does not connect to your store or change any price. You decide what to update, and Supplier Update Guard can prepare a reviewed Shopify import when you do. It does not read PDFs or inboxes, track stock, or watch competitors' websites.
Because the checks run on our server, your watch settings and the latest price list are stored there, encrypted. The privacy policy explains exactly what is kept and how to delete it.
Price
29 USD per month for up to 3 supplier files. Tax depends on your country and is shown at checkout. Cancel any time. Use the same email address at checkout as your BLZN Works account, then add your first watch under Price watches.
