FAQ

Questions before you join

Do I need a database for this?

No. The concept is simple file-to-file comparison: old supplier list in, new supplier list in, change report out.

Will it decide what prices I should charge?

No. It only detects supplier-list changes. It does not make pricing, financial, or margin recommendations.

Can it detect discontinued items?

It can flag items missing from the new file, but the final discontinued decision stays with you.

What should I describe when joining?

Mention how often suppliers send new files and which fields you need compared: cost, MAP, stock, title, barcode, or images.
