Features & Functionality

This list is still incomplete! If something isn’t listed, that may not mean that FOSSBilling doesn’t have support for it.

This page provides an overview of all functionality and if it is or isn’t implemented in FOSSBilling. If you see something that’s unimplemented and you’d like to have it added, consider contributing to the project!

Currency Support

Item	Supported	Planned	Notes
Multi currency support	✅		Some various limitations such as with currency formatting. General improvements are planned long-term.
Automatic exchange rate syncing	✅		Automatically enabled for new installations. Supports ExchangeRate-API, Currency Data API, and currencylayer for exchange rate data sources.

Security & Anti-Spam

Note: Many of the following require the “SpamChecker” module to be installed and must be configured under it’s settings.

Item	Supported	Planned	Notes
IP Address blocking	✅
reCAPTCHA	✅		Currently only v2 is supported. Support for more providers and versions is planned.
”Stop Forum Spam” integration	✅
Disallowing temporary / disposable email addresses from being used	✅		Uses the great FakeFilter project as a large, reliable list of temporary email address domains to filter out.
MFA/2FA	❌	✅	MFA/2FA support is considered a prerequisite before FOSSBilling reaches version 1 and is officially considered production-ready.
Activity logs	✅
Session hijacking prevention	✅		This is not an advanced implementation and leans towards not causing issues rather than being easily triggered.
Session age limits	✅		Defaults to 2 hours and may be adjusted via the configuration file.
Restricting staff member logins to certain IP addresses	✅		These are set via the “staff” settings. Be very careful as this may lock you out of the administrator panel.
FOSSBilling version-related alerts	✅		FOSSBilling will periodically query our “Central Alerts” API and will warn the administrator about major issues with the current version (such as a vulnerability).
CSRF prevention	✅		May be disabled via the configuration file.
Staff member permissions	✅
AbuseIPDB integration	❌	✅

DNS Management	❌	❓

Core Functionality

Item	Supported	Planned	Notes
Network interface selection	✅		It’s up to individual modules to respect the specified setting. All FOSSBilling ones should do and if they don’t it’s then a bug, however we can’t force a module built by a community member to use the correct interface & if one doesn’t the developer needs to address it on their end.

Recurring purchase pricing	✅
Promotional codes / discounts	✅		Some general limitations and less advanced than other options that may be available.
