Base Sequence Option

Alpha License: LGPL-3 OCA/server-tools Translate me on Weblate Try me on Runbot

This module allow user to add optional sequences to some document model. On which sequence is used, is based on domain matching with document values (and original sequence will be bypassed).

For example, it is now possible to,

  • Avoid using Odoo automatic sequence on invoice and vendor bill with old style sequence.
  • Customer payment and vendor payment to run on different sequence.
  • Assign different sales order sequence based on customer region.

This is a base module and does nothing by itself. Following are modules that will allow managing sequence options for each type of documents, I.e.,

  • Purchase Order: purchase_sequence_option
  • Invoice / Bill / Refund / Payment: account_sequence_option
  • Others: create a new module with few lines of code


This is an alpha version, the data model and design can change at any time without warning. Only for development or testing purpose, do not use in production. More details on development status
