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

All accounts and references are fictional. The amounts are pre-confirmed for this example. A flagged difference needs review; it is not a legal debt or money recovered.
Fictional 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.
The proposed sequence
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 proposed pilot 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 that figure does not establish
Thirty-six scenarios and twelve order and repeat-import invariants ran against structured, pre-confirmed inputs. Twenty checks returned UNKNOWN, as expected. It is not an independent audit, an accuracy estimate, evidence of production reliability or a customer outcome.

A pilot in development
Clause Copilot is being developed by Dylan, a solo founder in Sydney. This is a proposed founder-assisted pilot, not a finished automation platform. No paying Clause customers or customer results have been established in the supplied evidence.
This site accepts no real documents, applications or payments. Delivery and data-handling arrangements need to be settled before real records are supplied.
If your existing billing process already performs this check well, an additional service may not be useful.
Inspect the check for yourself
The sample shows a difference, a credit and missing evidence.
