A prototype we built for a manufacturing prospect. February to March 2026.

A spreadsheet that checks itself before it reaches the marketplace

A manufacturing prospect uploaded order workbooks to a marketplace by hand and had them rejected when a row was wrong. This prototype runs the rules the team kept in its head against the workbook first, names each failing row, and hands the clean rows to a simulated Salla upload.

The situation

The prospect had order workbooks that were uploaded to a marketplace by hand and rejected when a row was wrong. It asked for a recorded demo of the tool before engaging; there was no tool, so one was built in days: the rules a team keeps in its head, written down and run against the workbook, with the failures listed rather than hidden.

What we built

  • Workbook and CSV upload with a validation pass, rule by rule, against a rule set held outside the workbook

  • Rules for the fields the marketplace needs

    Order, customer, mobile, city and quantity present; Saudi mobile number format; coordinates; SKU; duplicate detection

  • Transforms, filtering and reports on the validated rows

  • Conditional workflow steps and email notifications when a run finishes or fails

  • A simulated Salla marketplace upload as the worked example, with per-row results so a rejected row is named rather than the whole file failing

  • Supabase storage behind the surface, with a run history and API notes

  • A second visual demo in March 2026 of the order-management and inventory dashboard the proposal went on to describe

What changed

The prospect had a working front end to react to before a proposal, and the proposal was written against what the demo showed rather than against a description. We walk through it on a call.
