A sub-ISO found years of residual variance in one audit

Residual statements had been accepted as correct since the business started, because nobody had the time or the method to check them line by line.

01 The challenge

  • Pricing and agreements had changed repeatedly; the statements had not kept up.
  • Variances were small per merchant and invisible in aggregate.
  • There was no model showing where portfolio revenue actually came from.

02 What we did

  1. 01 · Collect

    Agreements, schedules, residual reports, and merchant pricing data, handled under NDA.

  2. 02 · Audit

    A line-by-line reconciliation of statements against agreements and merchant data.

  3. 03 · Document

    A variance report with findings documented well enough to take to the processor.

  4. 04 · Institutionalise

    A monthly reconciliation process and a maintained pricing model the client's own team runs.

03 What changed

  • Variances documented and supported through the recovery conversation, which the client owned.
  • A pricing model the finance team refreshes quarterly.
  • Monthly reconciliation replaced the annual guess.
Questions buyers ask

Straight answers

The questions that come up when a buyer recognises their own portfolio in one of these.

How does an engagement start?
Every engagement opens with an Assess. We read your actual records and talk to the people doing the work today, then send back a written read of one to three pages: what is happening, what it costs or risks, which services fit, and which do not. It runs 1 to 4 weeks.
What does an engagement cost?
Every engagement is custom quoted after an Assess step. There is no rate card, no published pricing, and no standard engagement. The Assess is quoted separately and up front, and the engagement that follows is quoted against the scope you agree at the end of it.
Can we stop after the Assess?
Yes. The Assess is priced on its own and the written read is yours to keep whether or not you continue. If the problem is upstream of what we would be hired for, that goes in the read too.
How long does an engagement take?
The published timeline runs to 5 phases. Exact dates are set at the Assess step, once the scope is known, and each phase ends in a written decision rather than on a date.
Who actually does the work?
US-led, with global delivery centres. Teams are US-based, offshore, or blended; the client approves the model before work begins. A US-based practice lead owns every engagement.
Do you work inside our systems?
Yes, unless there is a written reason not to. We work in your portals, CRM, cloud accounts, and repositories under access that is scoped to the work, logged, and revocable by you at any time.
What do you need from us to start?
Read-only access or exports of the relevant records, two to four hours of your team's time, and the governing contracts and policies. Anything you share is handled under NDA.

Still not sure whether this is your problem too is what you need?

That is what the Assess is for. Book a 30-minute call and we will tell you which service fits, whether you need one at all, and what the first engagement would cost. We will also tell you when the answer is no.

Take the written read with you

Every engagement opens with an Assess: a written read of what is happening, what it costs, and what to do about it. It is quoted on its own and you can stop after it.
