case · revenue collection · public sectorAn entire university's revenue collection, in real time.
We replaced a legacy, vulnerable system with a web-based central cashier that validates every receipt instantly, gives leadership full visibility and leaves reports ready for Treasury.

Leadership sees, live, revenue by cashier, the best-performing fees, the cash closing and voided operations.
// the challenge
A legacy system and forgeable receipts.
The previous system was outdated and limited the real use of the software. Worse still: receipts could be forged, because the other departments had no way to validate them in real time or in bulk. Every procedure was a risk, and the central cashier had no visibility into what was happening.
// the solution
APIs that validate every receipt instantly.
We built a new web-based central cashier on a microservices architecture, and the key piece: we exposed APIs that every university system consumes to validate each payment in real time and in bulk, with identity verification against RENIEC. That closed the door on forgery. On top of that, students complete their procedures instantly and every transaction generates a unique reference.
// what we built
A complete platform, from the front desk to leadership.
Collection
Records payments tied to fees, prints the voucher/receipt and auto-generates a unique alphanumeric reference for every transaction.
Controlled voiding
Same day of payment only and exclusive to the Supervisor profile; it automatically generates the refund document.
Reports
History and revenue by cashier, day, month and year — exportable to Excel and ready to present to Treasury.
Dashboard
6+ indicators: highest-volume and most productive cashier, best/worst-performing fee, cash-closing comparison and voided operations.
Integrations (APIs)
APIs consumed by the university's systems (Intranet, Postgraduate, Procedures, Electronic Mailbox…) and the RENIEC API to validate every payment in real time and in bulk.
Management and configuration
Administration of users, offices, concepts and clients — the system adapts to the university's fee structure.
// inside the system
How it operates, on screen.
The cashier records the payment, selects the fee and the department, and the system issues the receipt with its unique reference — ready to print.
Revenue consolidated by period, exportable to Excel and PDF. The unit presents its settlement to Treasury without assembling anything by hand.
