create_invoiceread-onlyBuild a complete invoice as structured data: invoice number, issue and due dates, line items, discount, tax, total and payment terms. Nothing is stored. Use when the user wants an invoice for a client. Do NOT use for totals only (use calculate_totals) or for a printable text version (use render_invoice_text).
calculate_totalsread-onlyCompute subtotal, discount, tax and total for a list of line items (discount applied before tax, amounts rounded to 2 dp). Use for quick totals math without building an invoice. Do NOT use to produce an invoice document; use create_invoice.
supported_currenciesread-onlyList the currency codes InvoiceGen accepts for invoices (USD, EUR, INR, GBP, AED, SGD, AUD, CAD). Use before create_invoice when unsure whether a currency is supported. No exchange rates or currency conversion are provided.
render_invoice_textread-onlyBuild an invoice from the same inputs as create_invoice and return it as a plain-text document (header, line items, subtotal, discount, tax, TOTAL DUE, notes) ready to paste into an email or message. Use when the user wants readable invoice text. Do NOT use when structured fields are needed; use create_invoice.
