The problem
Most billing issues are discovered too late.
- An invoice is already issued.
- Accounting flags it days later.
- Support gets involved.
- Documents need to be reissued.
In most cases, the data was already wrong at the moment the invoice was created.
What InvoiceGuard does
InvoiceGuard runs a single check before an invoice or billing profile is created.
It looks at high signal issues that commonly cause problems later, such as:
- VAT validity and country mismatch
- Billing email risk and obvious issues
- Country consistency across billing fields
- Company domain sanity
It returns:
- a decision
- the reasons behind it
You decide how strict you want to be.
What it does not do
InvoiceGuard is not:
- an accounting system
- a payment processor
- a compliance authority
- a company enrichment tool
It is a guardrail, not a source of truth.
