Our method

How DigiInfra AI Digital structures telecom billing validation audits — from sample design to audit memorandum.

This page describes how we run a billing validation engagement end to end. If the steps match what your finance and revenue assurance teams need, request a review or browse engagements.

The path from sample to memorandum

Bound the question

We lock the product, cycle dates, tariff versions, and whether interconnect partners sit inside the review. Ambiguous scope is resolved before extracts leave your systems.

Design the sample

Stratified samples cover peak and off-peak, roaming and domestic, and known discount stacks. App analytics samples follow usage events that should reach mediation.

Reconstruct expected charges

Analysts apply the tariff in force for each event’s timestamp — including zone maps and settlement schedules — then compare to rated and billed amounts.

Trace material gaps

Gaps are traced to mediation filters, late partner feeds, rounding, stacked offers, or rating table mismatches. Speculative causes without evidence stay out of the memorandum.

Deliver and clarify

You receive a written audit memorandum and one clarification workshop. Remediation is yours to schedule; we can return for a follow-up check if invited.

What we need from your side

  • A product owner and a finance or RA contact
  • Masked extracts for the agreed fields
  • Tariff PDFs or machine-readable tables for the cycle
  • Known issues already under discussion (cutovers, partner disputes)

Where this sits among our engagements

The method above underpins the flagship Telecom Billing Validation Audit. Narrower rating reconciliations and interconnect reviews reuse the same reconstruction discipline with a tighter lens.
