Find, dispute, and recover telecom billing leakage with a practical sprint: inventory match → anomaly triage → disputes → credits verified applied.

Primary outcomes:

• Cost reduction: recover overbilling and stop recurring leakage
• Risk mitigation: reduces billing chaos and improves service accountability
• Carbon impact: not applicable

Beginner truth: Most telecom “billing complexity” is just unchallenged errors.

The most common telecom leakage patterns

1. Orphan services (circuits/lines billed but unused)
2. Rate drift (MRC increases without a documented change)
3. Duplicate billing (same service billed twice under different IDs)
4. Install/NRC surprises (charges without approval)
5. Taxes/surcharges spikes (unexplained or misapplied)
6. Credits not applied (promised credits that never hit the bill)
7. Wrong site/account mapping (services billed to the wrong entity)

30/60/90 telecom leakage sprint

Days 1–30: Build the proof base

• build/clean the telecom inventory
• match invoice lines to inventory
• classify anomalies and estimate $ impact
• start disputes for top 10 anomalies by $ and recurrence

Days 31–60: Recover + stop recurrence

• push disputes to credit issuance
• verify credits are applied (not just issued)
• disconnect or right-size orphan services
• update invoice QA rules and approval gates

Days 61–90: Lock the control system

• carrier QBR to resolve systemic issues
• renewal/contract terms review (auto‑renew, escalators, ETFs)
• implement monthly telecom close cadence

Step-by-step playbook

Step 1 — Create a leakage triage table

You cannot fix what you can’t list. Use the template below.

Step 2 — Assemble an “evidence pack” per dispute

Telecom disputes move faster when you include:

• invoice line item
• service identifier
• inventory record (or proof it’s unknown)
• contract/rate expectation (if available)
• requested resolution (credit + effective date)

Step 3 — Track to credits applied

A credit memo issued is not savings until applied.

Step 4 — Install prevention controls

• line/circuit ownership required
• change/disconnect workflow required
• invoice QA each month
• renewal deadlines tracked

Telecom Dispute Evidence Pack

- Invoice PDF page/line reference
- Identifier (circuit/phone/service ID)
- Inventory record link (or “unknown” flag)
- Expected rate / contract term (if known)
- Requested resolution:
  - credit amount
  - effective date
  - stop billing going forward if applicable
- Owner and escalation contact

Carrier Escalation Script

We are requesting resolution for the attached billing issues.
We need:
1) written confirmation of the correction
2) credit memo issuance
3) confirmation of the month the credit will apply
4) confirmation of billing stop date (if disconnect)

If unresolved by [date], we will escalate to [name/title] and review contract remedies.

Definition of Done

• invoice lines match inventory (unknowns are shrinking)
• top anomalies are disputed with evidence packs
• credits are verified applied
• orphan services are disconnected and billing stops
