YOUR WORKSPACE
Ready for next time.
Save column profiles and comparison totals to your account, then reuse them on another device. Original CSV files, SKU names and individual prices stay on your device. Summaries cannot reopen the full report.
Loading workspace…
Only uploaded when you save or restore. Free workspace: up to 100 entries; delete them at any time. Export full reports in Compare before closing the page. Sign in before selecting files, as signing in reloads the page.
Restore a workspace backup
Restores saved settings and summaries to your signed-in account. Existing IDs are skipped, not overwritten. If new entries exceed your available space, the whole batch is refused. This cannot restore original CSV files or full reports.
UNITCOST DESK PRO
More room for your work.
US$19 / month
Save up to 1,000 column profiles and comparison summaries across devices. Free accounts keep 100 entries. Full CSV comparison and report exports remain free.
Billed monthly in USD, automatically renewing until canceled. Manage payment details and cancel renewal in Stripe. After cancellation takes effect, existing entries stay readable, exportable and deletable; new saves use the free limit. Original CSV files and full reports are not stored.
Stripe sandbox · no real charges
Operator testing only. Use Stripe test card details, never a real card. An active test subscription expands capacity from 100 to 1,000 entries. When it ends or payment is overdue, new saves use the free limit; existing entries remain readable, exportable and deletable.
The workspace is free during this preview. Paid subscriptions are not available yet. No card required.
GUIDES & RESOURCES
A confident first comparison.
Sample files, practical answers and an offline edition. All free.
HOW THE COMPARISON WORKS
A small tool. A clear answer.
Unit cost = pack price ÷ units per pack. SKUs match exactly, including case and leading zeros. Duplicate or invalid rows are held for review instead of guessed.
Use comparable net prices. Currency conversion, tax, shipping, discounts, weight/volume conversion, PDF and Excel workbooks are outside this preview. Export your workbook as UTF-8 CSV first.
Try it with a real file
These fictional lists include a smaller pack that costs more per unit. Download both, then open Compare.
Unzip the offline preview and open index.html. It includes the local comparison tools; saved profiles and summaries require the online workspace. There are no paid features, purchases or licence keys in this release.
