Over a date range: what was credited back per currency and against how many invoices, what is still on order per currency, and every open order past its delivery date with days late. Pro; the list tools are free.

Credit one invoice: the whole invoice, a GROSS amount_minor split over its VAT rates, or named lines. Amounts store negative, reusing the invoice's own rates. Free: 5 a month. Send it with credit_note_text.

Remove one credit note never posted to its invoice and never rendered, freeing that month's slot; the invoice becomes creditable again. One with a dependent is refused: issue a fresh note to reverse a sent one.

Return one credit note in full by id or exact client name: every negated line, VAT lines, totals, the reason, and the invoice number and date it reverses. Reads only. Use credit_note_list for the ids.

List credit notes newest first: id, invoice, client, basis, reason, currency and the NEGATIVE total, with the amount credited per currency. Filter by invoice, client or issue date range.

Call this tool to write one credit note as an A4 PDF and return the path: the invoice layout titled CREDIT NOTE, with the invoice it reverses and the reason at the foot. Pro; credit_note_text is free.

Turn a credit note into a plain-text summary to paste into an email: the negated line table, VAT lines, total, reason, and what now comes off the invoice. Free; credit_note_pdf writes the A4 document.

Activate a Pro key (MCPL1.xxx.yyy) from checkout: verified offline against a built-in public key, saved to your config file. A wrong, malformed or expired key is refused, unsaved. license_status reads it back.

Raise a purchase order to a supplier from items and return its PO number and totals. unit_price is in MAJOR units; currency, VAT and the buyer block come from the shared profile. Free: 5 documents a calendar month.
