The world's best prepaid engine
Billing is not just about doing the maths. It is about doing the maths correctly, at any scale, under any pricing complexity, without ever getting it wrong — and recording every single thing that happened, permanently. That is what Seshnova was built to do.
What it takes to be the best
Most billing systems are built to handle the easy cases. The Seshnova engine was built to handle everything — including the cases you haven't thought of yet.
Precision
Charges must be exact. Not approximately right — exact. Every second of a session matters, and a billing engine that rounds incorrectly or misses a cutoff loses customer trust instantly.
Complexity
Real-world services don't have one price. They have thousands — varying by destination, time of day, day of week, geography, customer tier, and promotional status. The engine must handle all of it without breaking.
Scale
A billing engine that works for 100 customers must work identically for 100 million. Performance cannot degrade as your business grows. Provisioning and management must scale just as easily as the billing itself.
Reliability
Billing cannot have downtime. Every missed debit or duplicate charge is a direct financial loss. The engine must be resilient, self-correcting, and provably correct at every step.
Completeness
Every penny must be accounted for. A great engine produces a complete, immutable record of every event — so disputes can be resolved, audits can be passed, and nothing is ever lost.
Sessions are metered in real time, to the second
The moment a session starts, the clock is running. As usage accumulates, the balance is decremented live. When the credit runs out, the session ends — immediately and automatically. There is no polling delay, no batch reconciliation, no after-the-fact correction.
- Live balance tracking from session start
- Automatic cutoff at zero — no overspend
- Handles sessions of any duration
- Works for calls, time slots, data, access passes, and more
Thousands of rates. Always the right one.
A single service might have different prices depending on where the customer is calling, what time it is, what day of the week it is, what country they are accessing from, and whether they are on a promotional plan. Seshnova loads and applies all of these in real time — at any scale — without slowing down.
- Thousands of destination rates in a single product
- Geographic charge zones and country-level pricing
- Peak, off-peak, weekend, and holiday rate tables
- Timezone-aware billing — the right rate for the right time
- Per-customer pricing tiers and group discounts
- Promotional bonuses and top-up incentives
From your first customer to your ten-millionth
Seshnova was designed from the start to handle volume. Account provisioning, balance lookups, and session metering are all built to operate at scale without architectural changes as you grow. You do not need to re-platform when you succeed.
- Millions of accounts in a single deployment
- Bulk provisioning — issue credentials to millions in one operation
- Fast balance lookups regardless of account volume
- No performance cliff as customer numbers grow
Built to never charge the wrong amount
The hardest problem in billing is not calculating the price — it is guaranteeing that the right amount is charged exactly once, even when networks fail, retries happen, and systems restart. Seshnova uses a proven approach that makes duplicate charges and missed charges structurally impossible.
- Every transaction is uniquely identified — duplicates are rejected automatically
- Partial session charges handled correctly on disconnection
- No charge can be applied twice for the same event
- Corrections and reversals are fully supported with full history preserved
A complete financial record. Always.
Every balance event — account creation, top-up, usage charge, adjustment, reversal — is written to a permanent, append-only record at the moment it happens. Nothing is ever overwritten. If a customer disputes a charge, the answer is always there.
- Full history of every credit and debit
- Records are permanent — nothing is deleted or overwritten
- Supports financial audits, disputes, and reconciliation
- Balance at any point in time can be reconstructed from the record
Building it yourself vs. Seshnova
Every company that sells prepaid services eventually faces the same choice. Here is what that choice actually looks like.
The best prepaid engine in the world
Not because we say so — because the problems it solves are the hardest ones in prepaid billing, and it solves them reliably, at scale, every time. If you sell any kind of prepaid service, this is the engine you want under the hood.
