As the server listed them on Oct 25, 2026. Descriptions are the server’s own words; hidden characters are shown as [U+…].

• accept_invoice_changeaccept invoice changecan change or delete data

  Apply one suggested invoice change after the freelancer explicitly approves that change. Pass confirmed true only then. This is the path that may add a line, change a rate, apply a discount, or move the due date. Calling it is not a substitute for the freelancer's approval.

• begin_invoicebegin invoice

  Start a draft invoice. Draft figures are not an approved commitment until seal_invoice. Currency is a three-letter code. Amounts later are minor units of that currency and are the freelancer's figures.

• describe_linedescribe linecan change or delete data

  Correct a line description while the invoice is still a draft. After approval, a different description is refused. Use suggest_invoice_change with add_line for a different line.

• list_invoiceslist invoicesread-only

  List the signed-in freelancer's invoices. Use a returned id with read_invoice. Do not guess an invoice.

• offer_discountoffer discountcan change or delete data

  Record a discount the freelancer is putting on the invoice. kind none uses value 0. kind percent takes a whole number from 1 to 100. kind fixed takes a whole number of minor units. After the invoice is sealed, a different discount is refused until accept_invoice_change applies an apply_discount suggestion. Do not invent a discount.

• place_lineplace linecan change or delete data

  Add one line: description, quantity, rate in whole minor units, and unit hour, each, or day. After the invoice is sealed, a new line is refused until accept_invoice_change applies an add_line suggestion.

• quote_line_ratequote line ratecan change or delete data

  Set the rate already chosen for one line, as a whole number of minor units in the invoice currency. After the invoice is sealed, a different rate is refused until accept_invoice_change applies a change_rate suggestion.

• read_invoiceread invoiceread-only

  Read the invoice before answering. Quote only this record. Draft status is not an approved commitment. Proposed changes do not authorize a new line, a different rate, a discount, or a new due date.

• seal_invoiceseal invoicecan change or delete data

  Mark the current draft as the approved invoice. Pass confirmed true only after the freelancer explicitly approves the lines, quantities, rates, due date, late terms, and any discount already on the draft.

• set_invoice_dueset invoice duecan change or delete data

  Set the due date as a calendar day in YYYY-MM-DD form. After the invoice is sealed, a different date is refused until accept_invoice_change applies a move_due_date suggestion.

• set_line_quantityset line quantitycan change or delete data

  Set the quantity on one line. After the invoice is sealed, a different quantity is refused until accept_invoice_change applies an adjust_quantity suggestion.

• suggest_invoice_changesuggest invoice change

  Record a suggested change. This does not change the invoice. kind add_line requires description, quantity, rateMinor, and unit. kind change_rate requires lineId and rateMinor. kind apply_discount requires discountKind, discountValue, and discountNote. kind move_due_date requires dueOn. kind adjust_quantity requires lineId and quantity. kind revise_late_terms requires graceDays, lateBasis, feeMinor, latePercent, and lateNote.

• write_late_termswrite late termscan change or delete data

  Record late terms: grace days, and a basis of none, flat_fee, or percent_per_period. flat_fee uses feeMinor and a percent of 0. percent_per_period uses percent and a fee of 0. After approval, a different basis, grace, fee, or percent is refused until an accepted revise_late_terms suggestion.
