Create draft invoice
Create a draft invoice for a customer with lines. The draft is not booked.
MCP tool e_conomic_write → create_draft_invoice
write
Creates a draft with the customer, date, currency, payment terms, layout and lines. The recipient name and VAT zone are copied from the customer. The draft stays editable and is not booked, so it reaches no one and runs without asking first. Lines take a product number or a free text with quantity and unit price. Returns the draft number and net, VAT and gross totals.
