Nothing disappears quietly
Voiding a sale or a payment requires a reason, and who did it is logged.
Case study
Alto Vivo
A system that lets small businesses sell, manufacture, collect payments, balance the till and run payroll from their phone.
The challenge
Many small businesses track who owes them in a notebook, close the till without knowing if it balances, and run payroll with a calculator. Existing systems are usually built for large companies or for a single type of business.
The approach
Instead of one huge system, we designed a modular product. The business answers three questions — what it does, whether it has employees, and whether it sells on credit — and Alto Vivo switches on only the modules it will use. Each module solves one concrete daily task.
What we built
Eight modules you can switch on and off
- 01Sell
Cash, mobile wallet, card or credit, with a printed or WhatsApp receipt.
- 02Products
Variants, sizes and colors, batches, expiry dates, multiple warehouses and Excel import.
- 03Production
Work orders, batches, each worker's output and numbered delivery notes.
- 04Receivables & payables
Credit limits, partial payments and balances, with overdue customers first.
- 05Money
Tills with daily close, safe, bank accounts and expenses.
- 06Employees & payroll
Bonuses, severance, vacation, contributions and loans deducted automatically.
- 07To-dos
What's running low, what's due and who to collect from today.
- 08Team
Role-based access: everyone sees their part and every action is logged.
