As published by CostRift — verify anything time-sensitive on their site.
What file formats does CostRift support?
CostRift supports CSV and XLSX file formats for comparing supplier price lists.
Do my supplier files leave my browser?
No, supplier price lists are processed locally in your browser and are never uploaded to CostRift servers.
Can I compare price lists from different suppliers?
CostRift is designed to compare an older and a newer price list from the same supplier, as comparing unrelated catalogs can lead to misleading matches.
How does CostRift match SKUs?
CostRift matches products by SKU, attempting an exact match first and then normalizing for whitespace and case if necessary.
Do I need selling prices to use CostRift?
No, you can compare costs with just SKU and cost columns, but adding selling prices enables margin impact calculations.

Hi! I’m David, the solo maker behind CostRift. I built it for businesses that regularly receive updated supplier price lists and need a faster way to understand what changed and how those changes affect margins. I’d especially love feedback from people who currently handle this process in Excel or Google Sheets. What part of comparing supplier updates takes the most time in your workflow?
