Vendor Billing & Contract Audits

We find the money
you're already
spending wrong.

Mako Consulting audits your vendor contracts, invoices, and inventory against actual usage — surfacing overbilling, ghost inventory, and mispriced services, then helping you recover the credits and renegotiate the agreements.

No savings identified, no fee. You see the findings before you pay anything.

Vendor categories we audit — industry-agnostic by design

  • Telecom & Network
  • SaaS & Licensing
  • Facilities & Utilities
  • Insurance
  • Logistics & Freight
  • Waste & Services
The Problem

Nobody reads the invoice as closely as the vendor who wrote it.

Invoices nobody reconciles to the contract

Rates drift, promo pricing expires, surcharges get added. We match every line item back to the signed agreement and flag what does not belong.

Ghost inventory you are still paying for

Circuits, licenses, lines, and equipment that were cancelled, replaced, or never used stay on the bill for years. We validate the inventory against actual usage.

Contract sprawl across too many vendors

Auto-renewals, overlapping scopes, and inconsistent terms across dozens of agreements. We build the single inventory nobody has had time to build.

What We Audit

Contracts, invoices, and inventory — reconciled against reality.

Vendor Billing Audit

We pull 24–36 months of invoices and reconcile every charge against the contract, the rate schedule, and actual usage. Overbilling, duplicate charges, expired promotional rates, and mispriced services get documented line by line.

  • Invoice reconciliation
  • Rate validation
  • Credit and refund claims

Inventory Validation

Circuits, licenses, seats, meters, containers, and equipment get verified against what is actually in service. Anything billed but not used becomes a removal candidate with a documented savings figure.

  • Asset-to-invoice match
  • Ghost inventory removal
  • Usage reconciliation

Contract Compliance Review

We read the fine print: term and renewal language, price escalators, SLA credits, minimum commitments, and termination rights — then show where the vendor is not holding up their side.

  • Term and renewal audit
  • SLA credit recovery
  • Escalator review

Recovery & Renegotiation Support

Findings are worth nothing until the money moves. We prepare the claim, sit in the vendor conversations, and restructure the agreement so the corrected pricing holds going forward.

  • Credit recovery
  • Vendor negotiation
  • Restructured terms
How Engagements Work

Audit, findings, recovery. You see the numbers before you pay.

01

Baseline & Data Pull

You forward invoices, contracts, and vendor statements. We build the spend inventory — no system access or IT project required.

02

Line-Item Audit

Every charge is reconciled to contract terms and actual usage. Discrepancies are documented with the supporting invoice page and clause.

03

Findings Report

You get a dollar-quantified findings list: recoverable credits, removable inventory, and mispriced services, ranked by size and effort.

04

Recovery & Renegotiation

We pursue the credits and take the renegotiation to the vendor with you, then re-verify the following billing cycles to confirm the fix stuck.

About

We read the fine print for a living.

Mako Consulting Co. is a cost and vendor advisory firm. We do one thing: audit what your vendors bill you against what they contracted to deliver and what you actually used — across telecom, SaaS, facilities, insurance, logistics, and services spend.

We are industry-agnostic because billing errors and contract sprawl look the same everywhere. We are not a reseller, we take no vendor commissions or referral fees, and we are not strategy consultants — we do not do fundraising, board reporting, or FP&A. Our scope starts and ends at vendor spend.

“Every dollar we find was already leaving your business. We just make it stop.”

How We Think About It
How We Work With You

The audit pays for itself, or it costs you nothing.

Our fee comes out of validated savings. If we find nothing, you owe nothing.
