Capabilities

Tools 16

billing_docs_report

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.

Discovered
credit_note_create

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.

Discovered
credit_note_delete

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.

Discovered
credit_note_get

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.

Discovered
credit_note_list

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.

Discovered
credit_note_pdf

Call this tool to render one credit note as an A4 print-ready document and return a download link valid for one hour: the invoice layout titled CREDIT NOTE, with the invoice it reverses. Pro.

Discovered
credit_note_text

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. Also a .txt download link valid one hour. Free; credit_note_pdf writes the A4 document.

Discovered
license_activate

Turn Pro on for this connection with key, an MCPL1.<payload>.<signature> issued at checkout for this server or the bundle. Data under your token stays; a wrong or expired key changes nothing. license_status confirms it.

Discovered
license_status

Report this endpoint's licence state for your token as JSON: the product, the tier free or pro, why it is not Pro, and the checkout URL. Call it to explain a free-tier refusal. No arguments, nothing changes.

Discovered
purchase_order_create

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.

Discovered
purchase_order_delete

Remove one purchase order with nothing received and never rendered, freeing that month's slot. One with a receipt is refused, naming it. The PO number is never reissued. purchase_order_receive logs arrivals.

Discovered
purchase_order_get

Return one purchase order in full by id or exact supplier name: buyer and supplier blocks, every line with unit price and VAT, totals, the delivery date, status and every receipt with its date and note.

Discovered
purchase_order_list

List purchase orders newest first: id, supplier, order and expected delivery dates, status open, partially_received or received, currency, total and received date. Filter by status, supplier or date range.

Discovered
purchase_order_pdf

Call this tool to render one purchase order as an A4 print-ready document and return a download link valid for one hour: the invoice layout titled PURCHASE ORDER, with the buyer and supplier. Pro.

Discovered
purchase_order_receive

Record that an order arrived. partial keeps it open and can be repeated, each receipt kept with its date and note; a full receipt closes it. An order already received, or a date before the order date, is refused.

Discovered
purchase_order_text

Turn a purchase order into a plain-text order to paste into an email: the line table, VAT lines, total, and a line asking the supplier to deliver by the date and quote the PO number. Also a .txt download link valid one hour. Free on every tier.
