Traffic and settlements

A carrier rate, a provider plan, a reseller price and a customer tariff are separate calculations. The software keeps them apart and reconciles each one.

How a project runs

From audit to support

  1. Audit

    We map your switches, carriers, rate decks, billing data and integrations, and what already works well.

  2. Design

    We agree the modules, interfaces, data model and acceptance criteria for the first stage.

  3. Build and integrate

    We implement, connect carriers and systems, and load your tariffs and accounts.

  4. Parallel run and cutover

    New and current systems run side by side until rated records match. Then traffic moves in stages.

  5. Support

    We maintain and extend the system on agreed terms, with updates tested before release.
