CatchWeight Logistics
Order-to-invoice system for a Tobago fish distributor, built around the exact weight delivered.


The story
Fish is ordered by an estimate and delivered by exact weight, so the invoice never matches the order. CatchWeight Logistics bridges that gap for a Tobago fish distributor, from the order to the signed invoice.
Wholesale fish and meat is sold by weight, but nobody knows the exact weight until it is cut and packed. Without a system, every invoice has to be reworked by hand after delivery. Now the system records what was ordered and what was delivered, and bills the real weight.
What I built
- Orders taken by estimated weight and invoiced by delivered weight
- Driver, sales rep and PO details on every order
- Signed proof of delivery printed on the invoice
- Letter-size invoices and 80mm thermal receipts
- The owner can run the business from overseas
