"Assumptions"
"Defaults are a fictional example. No deductible, coverage or payer amount is inferred."
"Use one invoice version and a consistent tax basis. This worksheet is not an insurance coverage determination."
"Receipts are gross applied payments before card fees. Payment fees belong in the shop's expense records."
"Negative payer balances and over-assignment remain visible for review. They are not automatic refunds or permission to rebill."

"Result notes"
"Enter payer amounts only after responsibility has been confirmed. This tool does not determine insurance coverage, deductibles or reimbursement rights."
"Receipts are gross amounts applied to this invoice before processing fees. A processor fee does not create a new customer or insurer balance."
"Negative payer balances identify an excess receipt or an allocation error to review. They do not authorize a refund automatically."
"Use the same invoice version and currency throughout. Include tax consistently in the invoice and assigned payer totals."
