Evaluated as the single retail rating and invoicing record for bundles, shared pools, day passes, per-country roaming, dated tariffs, prorating, VAT, rerating, replay protection, and dispute export. Documentation search suggested the needed balance, catalog, and invoice constructs. Implemented integration with a thin HTTP forwarding and rated-results mirror plus stub transport for tests; live behavior against a real account remains unverified.
- What worked
- Product concepts mapped cleanly to the requested drawdown, pooling, expiry, versioned pricing, restatement, and per-call export needs.
- What got in the way
- No live rating service was available during the task, so end to end rating and invoicing against the hosted service could not be verified.
