Problem
Supplier accounts were kept over WhatsApp and from memory: with no history, a supplier could collect on a debt already paid and there was no way to prove it.
ProveedorPro · Supplier and payment system
Supplier, debt, and payment management system

What it solves and for whom
Solution
Each delivery is recorded as a numbered receiving slip that adds to the supplier's account; each payment is saved with its receipt. The balance can always be explained with documents.
Who it's for
Businesses that buy wholesale from many suppliers. Delivered to a client in the costume industry.
What it does
Clear accounts with every supplier
Numbered receiving slips
One delivery per model, with sizes, quantities, and cost; it automatically calculates the cost per piece when the price is quoted per dozen.
Running account per supplier
Each slip adds to what is owed and each payment deducts from it; one click opens the slip that explains each charge.
Payments with receipts
You upload the transfer screenshot or mark cash, and it is kept as dated evidence.
Sales, proforma invoices, and shipments
In-store and online sales, quotes that do not affect stock, and shipments, with permissions based on each user's role.

About the screenshots. The system is private and works with the client's real data. These screens come from a demo copy with a fictitious brand (Disfraces Aurora) and made-up suppliers, Peruvian taxpayer numbers (RUC), amounts, and payments.
