Zaijin keeps a carpenter’s materials and reimbursements in one workflow
A smartphone-based tool for small carpentry businesses to estimate material quantities, prepare supplier orders, track purchases and returns, and compile reimbursement invoices.
- For
- Solo carpenters and small carpentry businesses
- Worth noticing
- Board quantities appear in both area-based and layout-based counts, with the intermediate calculation shown for checking.
Field notes
The workflow links room-level quantity estimates to supplier-specific orders, then tracks later additions, returns, and discounts against each job. For gypsum board, the page describes both area-based and layout-based counts and displays the calculation so users can check it; the carpenter still chooses the order quantity. The site also says its CSV exports support tax-preparation work but are not a substitute for accounting software.
