Only call this when the user has clearly asked to issue this exact draft. Fiken: POST /companies/{companySlug}/invoices/drafts/{draftId}/createInvoice.

fiken_list_contacts

Customers and suppliers. Filter by name, organization number, email, customer/supplier flag or modification date. contactId in the result is the id other tools take as customerId/contactId. Fiken: GET /companies/{companySlug}/contacts.

Documents waiting in the company's inbox (receipts and bills uploaded for bookkeeping). Fiken: GET /companies/{companySlug}/inbox.

Registered hours (Fiken Timeføring). Fiken: GET /companies/{companySlug}/timeEntries.

fiken_list_transactions

Ledger transactions (one per bookkeeping event) with their entries. Fiken: GET /companies/{companySlug}/transactions.

fiken_send_invoice

IRREVERSIBLE. Delivers an issued invoice to the customer by email, EHF, eFaktura, SMS or physical letter (a letter costs extra and goes to Norwegian addresses only). A sent message cannot be recalled and Fiken records the invoice as sent. Only call this when the user has clearly asked to send this exact invoice to this recipient. method lists delivery channels in priority order; Fiken uses the first one that works. Fiken: POST /companies/{companySlug}/invoices/send.
