A practical control layer
Everything needed for a cleaner invoice handoff.
Not another accounting platform. A reusable operating record for the customer-specific details your existing software does not hold.
Pre-send checklist
A short repeatable check your team can use before every invoice submission.
Visible uncertainties
Missing and conflicting instructions remain explicit questions instead of becoming unreliable assumptions.
The expensive part is often invisible
Your accounting software creates the invoice. It rarely remembers how each customer accepts it.
How the pilot works
From scattered instructions to a reusable control.
A focused human-reviewed pilot, delivered without changing your accounting system.
- 1
Share only the instructions
Send redacted billing guidance, onboarding notes or portal instructions. Prices and bank details are not needed.
- 2
We structure and source every rule
BillPreflight extracts requirements, flags conflicts and marks anything that still needs confirmation.
- 3
Confirm your rulebook
You review the draft before it becomes your reusable pre-submission checklist.
Private by design
We need billing instructions—not your whole contract.
Raw pilot documents are used only to prepare your rulebook and are deleted seven days after approval. We do not request bank information, contract prices or unrelated commercial terms.
- ✓ Every statement shows its source
- ✓ Unknown details stay visibly unknown
- ✓ No public sharing without explicit opt-in
- ✓ Delete your rulebook whenever you choose
