Billing and finance backend for a multi-center healthcare practice — patients, procedures, transactions, discount governance, and a live CFO dashboard, built as the financial companion to Nexus Reporting.
A multi-center healthcare business — a pharmacy plus related clinical facilities, run as several "Nexus centres" — generates cash, card, and bank transfer revenue across departments and procedures every single day. Without a live rollup, the CFO's actual financial picture arrived weeks late, reconstructed from receipts and reconciliations, by which point a bad month was already locked in rather than something that could still be steered.
There was a second, quieter problem too: discounts. Front-desk staff need the ability to offer one, but not the unilateral authority to grant one — and without a system for that, "how much did we give away this month, and who approved it?" wasn't a question anyone could answer quickly.
Nexus Finance is the billing and finance system for the practice — patient and procedure records, transaction entry, doctor management, and reporting — built as a separate companion system to Nexus Reporting (the clinical reporting app), the two talking to each other over a signed service-key API rather than sharing a database. Front-desk staff record transactions and request discounts; a CFO dashboard rolls everything up in real time — net revenue, payment-method split, top procedures by revenue, per-department breakdown — and a formal End-of-Day Closing process locks each day's books rather than leaving the ledger perpetually open.

The CFO dashboard for one of the centres — figures blurred for confidentiality.
center_id, the same tenancy model shared with Nexus Reporting — multiple physical centres run on one system without data ever crossing between them.| Backend | Plain PHP API + MySQL, no framework |
| Integration | Signed service-key API shared with Nexus Reporting (Laravel) |
| Reporting | Live CFO dashboard — revenue, collections, discounts, per-department and per-procedure breakdowns |
| Hosting | Hostinger shared hosting |
In build, developed alongside Nexus Reporting as the financial half of the same practice-management platform.
If revenue, collections, or discount governance in your business only becomes clear weeks after the fact, that's a solvable problem.
