Workflow Playbook
Turn receipt or billing inputs into a checked invoice by normalizing amounts, applying the right tax path, validating identifiers, and producing a PDF, receipt, or XLSX record.
Hubs
A reliable billing document begins with evidence, not a formatted total. Extract receipt or invoice data into fields, but keep the original image or text nearby so the supplier, date, line items, currency, and amount can be checked. When a value uses mixed commas, periods, or spaces, normalize the notation before doing any tax arithmetic.
Sales tax and VAT are different calculation paths. Record whether tax is added to a net amount or extracted from a tax-inclusive amount, and verify the currency code, VAT number, and payment details that will appear on the final document. These tools check calculations and formats; they do not determine the legal rate or filing obligation.
Generate a PDF invoice, payment receipt, or editable XLSX workbook only after the values are reviewed. Reconcile each line, subtotal, tax amount, grand total, recipient, and payment instruction with the approved source data. Save that comparison with the delivered document so a later accounting or customer question can be answered from the record.
Workflow playbook
Use ai-image-to-receipt-json for a receipt or invoice image. For pasted or exported text, use currency-extractor for simple values or ai-currency-extractor when labels and surrounding context are needed. Preserve the source image or text beside the extracted fields.
Use text-currency-normalizer to standardize money expressions, number-format-cleaner to resolve mixed decimal and grouping conventions, thousands-separator for the final display convention, and currency-validator to check the three-letter currency code. Do not silently convert a stated amount into another currency.
Calculate the selected sales-tax or VAT treatment from the normalized taxable amount. Validate a VAT number with vat-validator or eu-vat-validator when relevant, and check payment coordinates with iban-swift-validator before placing them on the document.
Generate the document that fits the handoff: pdf-invoice-generator for a formal invoice, pdf-receipt-ticket for a paid receipt, or xlsx-invoice-generator for an editable workbook. Compare line subtotal, tax, currency, total, identifiers, and recipient details against the reviewed inputs before delivery.
Use sales-tax-calculator for a sales-tax amount and vat-calculator when VAT must be added to or extracted from a price. A calculator result does not determine the applicable legal rate; confirm the jurisdiction and tax treatment first.
Use pdf-invoice-generator for a customer-facing invoice, pdf-receipt-ticket for a compact payment receipt, and xlsx-invoice-generator when the recipient needs an editable invoice or quotation workbook.
