change_order_createOpens a change order against Q-2026-014
change_order_add_lineAdds the window line
contract_valueShows the new total

Contract value goes from PLN 58,000 to PLN 60,300 net once approved, with the change on record.

Example from "Client adds a bathroom window". Invented names, real math from the tools.

When a client adds or removes work after the quote is signed, record it as a change order. It keeps the delta lines, tracks approval and always knows the current contract value. On Pro it writes the change order document and the invoice lines.

Made for Builders and contractors, Agencies, Consultants

Change Order

Change orders from chat

Change orders against a quote or work order, with deltas, approval and the running contract value. Uses the Change Order server. One URL, no install. 9 tools.

You get: Report

All tools (9)

ToolWhat it does
change_order_add_lineAdd one line to a draft change order: added or removed with a quantity and a unit price in minor units, or changed with the old and the new quantity and price, each with a reason and a date.
change_order_createRaise a change order against a quote or work order and return its CO-YYYY-NNNN number: the reference, the client, a title, the date, and the original contract value in minor units.
change_order_deleteDelete a DRAFT change order with no lines, freeing an open slot.
change_order_documentRender one change order as a plain-text document for the client to approve: every line with its reason, the delta net and gross, the contract value before and after, and an approval block.
change_order_getReturn one change order in full by CO number or client: every added, removed and changed line with its reason and delta, VAT, delta gross, the status history and the running value.
change_order_invoice_payloadBuild the approved delta as invoice_create-ready items in MAJOR units and quote_create-ready items in MINOR units, with VAT at the shared profile rate.
change_order_listList change orders newest first with status, reference, client, currency and net delta, and above them the APPROVED and the pending delta per currency, kept apart.
change_order_statusMove one change order along and stamp the date and note: draft to sent, sent to approved or rejected, either to void.
contract_valueThe running value of one quote or work order: original, approved deltas and current value, with pending draft and sent deltas kept apart.

Questions

Does a rejected change order count against the limit?
The free limit counts open orders, draft and sent.
Can it remove work as well as add it?
Yes. A line can add, remove or change quantity or price, so the delta can be negative.
