FlexBill is the modern billing and captive-portal platform for Tanzanian ISP operators. Multi-tenant. Voucher-ready. RLS-secured.
From capturing a customer's voucher code to reconciling monthly revenue across every router you operate — FlexBill handles the whole billing lifecycle.
A branded portal your customers actually enjoy using. Voucher redemption in one tap, package selection, and self-service — no phone calls to your support line.
Every ISP gets its own isolated workspace. Row-Level Security is enforced on the database — a query from one tenant can never return another tenant's customers, payments, or routers. Not by convention. By construction.
Register routers, push package updates, watch sessions live. FlexBill talks to your MikroTik routers over encrypted WireGuard tunnels — no exposed API ports, no shared passwords.
Passwords hashed with Argon2id. Sessions hardened with Secure + HttpOnly + SameSite cookies. CSRF protection on every state-changing request. Tamper-evident audit logs. MFA-ready.
FlexBill is built for operators who handle real money and real customer data. Every layer assumes a hostile client.
Row-Level Security on every tenant table. Enforced at the database layer, not in application code. A bug in the app can't leak across tenants because PostgreSQL won't return the rows.
Argon2id password hashing. Memory-hard, GPU-resistant. Every password is stored as an Argon2id hash with per-user salts. Nothing is stored in plaintext, ever.
Hash-chained audit logs. Every login, every change, every sensitive action is written to an append-only log with a cryptographic chain. Tampering is detectable.
If you run MikroTik hotspots, WISPs, or community networks — FlexBill is for you.
"We used to run our hotspot on a spreadsheet and a WhatsApp group. Now customers redeem vouchers themselves and I see every session live."
"Multi-tenant was the reason we chose FlexBill. We run four separate networks and each one is completely isolated — no risk of mixing customer data."
"The WireGuard integration means my routers don't expose any management ports to the internet. That alone was worth switching."
