What we help you get right

Inventory, billing accuracy and renewals, kept current.

Where we help

  • An inventory of services, circuits, lines and licenses across sites
  • Invoices checked against contracted rates, line by line
  • Billing errors identified and disputed on your behalf
  • Contract and renewal dates tracked well in advance
  • Reporting your finance and AP teams can use
  • Escalation support when a supplier issue needs weight behind it

Signs it’s time to review

  • Invoices are hard to reconcile against what was agreed
  • Nobody owns the full inventory of services and sites
  • A renewal date caught you off guard in the last year
  • Finance is asking for a clearer view of recurring spend
  • You have grown through acquisitions or new sites

How we work on expense management

Design, Negotiate, Implement, Support.

The same four steps, applied to what you already run.

  1. 01

    Design

    We build the inventory and agree what gets checked, how often, and who sees the reporting.

  2. 02

    Negotiate

    When a billing error or a renewal comes up, we bring the contract, the data and leverage to the conversation.

  3. 03

    Implement

    Disputes are filed and tracked with the supplier until they are resolved, with you kept informed.

  4. 04

    Support

    Monthly checks, renewal monitoring and a named advocate who knows your accounts. The supplier bills the service; we check the bill.

Expense management at no cost to you.

Book a 30-minute meeting and we’ll show you exactly how that works, and what a billing review could look like for your organization.

FAQ

Expense management questions we hear often.

What does expense management cover?

An inventory of your services, circuits, lines and licenses; invoices checked against contracted rates; billing errors identified and disputed on your behalf; and contract and renewal monitoring. It applies to services we helped you put in place and, where it makes sense, to services you already had.

Do you recover the money from billing errors?

We identify and dispute billing errors on your behalf and track each dispute with the supplier until it is resolved. Credits and adjustments come from the supplier. Since 2024 we have identified and disputed $1M+ in billing errors on behalf of clients.
