Contract billing check
Check your invoices against what was agreed.
Compare customer-confirmed prices and approved changes with invoice and credit records. See the differences that need a closer look.
ExampleOne finding, one line

July 2026
Potential underbilling
Every finding names the clause it relies on and the record it was compared with, so you can trace it back.
The same period, read three ways
One billing period, three different findings

Example CC-041 / July 2026
What the check actually puts side by side
Three views of one agreement. The reference, the record, then the difference between them.
Agreement CC-041 Clause 4.2 Basis Fixed recurring fee Confirmed fee A$3,120.00 Effective from 1 July 2026 Confirmed by Customer, before comparison
Amounts exclude GST. The customer confirms the fee and the period before anything is compared. The check does not read a rate out of a contract on its own.
Invoice INV-2041 Line 1 Period July 2026 Invoiced A$3,000.00 Credits applied None Net recorded A$3,000.00
A properly allocated credit reduces the net recorded amount. Records have to belong to the same agreement and the same period to be comparable.
Confirmed expected A$3,120.00 Net recorded A$3,000.00 Difference A$120.00 Direction Billed below the reference Status Potential underbilling
A flagged difference is for review. It does not establish a collectible debt, service delivery or an entitlement to change an invoice.
How a review runs
Records in, confirmed reference, then a comparison
Four stages, in order. Nothing is compared before you confirm the terms it is compared against.
Confirm the reference schedule
You confirm the current fee, the effective period and any approved exceptions, with source references.
Compare like with like
The confirmed fee is set against the billing records for the same agreement and the same period.
Decide what the finding means
You or your authorised adviser decides any next action. A difference alone settles nothing.
Why the order matters
The reference comes first
A comparison is useful only when the agreed terms are clear.
The review starts with your agreements and approved changes. You confirm the current fees, the relevant period and any conditions before those amounts are compared with billing records.
A credit can explain an apparent difference. An approved waiver can be a valid exception. A missing amendment leaves a question to resolve.
- Agreed terms
- A source-linked reference schedule that you confirm.
- Actual billing
- Invoices and credits allocated to the same agreement and period.
- Your review
- A comparison report with supporting records and unresolved questions.
What you receive
Three things, at the end of a review
Everything is traceable to a document you supplied.
A confirmed reference schedule
Every billing term from your agreements in one table, each one showing the document and page it came from. You confirm it before anything is compared.
A comparison report
Each billing line marked as a match, a difference to review, an accepted exception, or missing evidence. Differences show the arithmetic.
A review discussion
We go through the findings together so you can decide what to act on, and what to record as deliberate.
Who you are dealing with
One person, in Sydney
Clause Copilot is run by Dylan Abreu from Sydney. Reviews are delivered personally, which is why the scope is capped at five agreements and three months of records. That cap is deliberate. It is the amount of work that can be done carefully.
Every figure in a report traces back to a document you supplied. Where a referenced amendment is missing, the review says so rather than estimating a number to fill the gap.
If your billing process already catches these differences reliably, you do not need this. That is worth establishing in the first conversation rather than after you have paid.
