Understand Multi-Lingual Invoices
Last updated on Sep 19, 2026
Advanced Billing renders invoices in English by default. With Multi-Lingual Invoices, you can supply your own translations so each customer sees their invoice in their own language, and refine those translations down to a specific region's dialect where it matters.
Requirements
This feature is available once your site is on Relationship Invoicing. Configuring it requires the permission described as manages product catalog, settings, and integrations.
How the pieces fit together
Three pieces work together:
- Customer Locale - the language, and optionally the region, recorded on each customer.
- Language customization - the Languages you create and the invoice wording you override in each.
- Language application - the order Advanced Billing applies those Languages in when it builds an invoice.
The locale on the customer is the input; the Languages you have defined are the available translations; the application order decides which one wins when more than one could apply.
Layering a region over a base language
You can create a standardized version of a language, such as a base German translation, and then layer region-specific overrides on top of it where a dialect differs.
This means you do not have to maintain a complete translation per region. Translate once into the base language, then override only the specific wording that differs in a given region: everything you do not override falls back to the base.
