Sometimes my clients want to put line items on deals without creating/publishing a quote, either as a way to estimate the size of the deal early on or because they need line items for revenue calculations/fulfillment but DON'T intend to actually quote/contract through HubSpot. Since the quote.hapily line items sidebar is/has been read-only, the only way to use the rules engine for line items is to create/publish a quote, since line items won't be created until that point. It would be awesome to be able to edit line items as a standalone extension, similarly to how HubSpot does it out of the box, just with all the quote.hapily goodness. EDIT 03.19.2025: Another reason that someone would want to be able to create/edit line items separately from the Quote builder UI is that they might want to use line item data to perform custom automation that they want to then feed back into the eventual quote (e.g. making API calls to calculate Shipping or Tax amounts from external sources). Requiring a rep to publish a quote that will never be sent to the client so that they can create line items that drive that process is confusing in lots of ways.
