Installation & requirements

Requirements

Requirement	Notes
Craft CMS 5, Pro edition	Required, because business accounts rely on multiple users. The Solo edition only supports a single user and cannot run the B2B flows.
Craft Commerce 5 (^5.0)	The EU VAT ID validation & reverse charge feature is built on Commerce's native VAT support, which arrived in Commerce 5.3; on Commerce 5.0–5.2 every other feature works, but leave Validate VAT IDs off. All other pillars have no minimum beyond Commerce 5.0.
PHP 8.2 or newer
MySQL or PostgreSQL	Both are supported and verified against clean installs. The plugin uses only Craft's query builder, so it runs on either of Craft's supported databases.

Install with Composer

composer require totalwebcreations/craft-b2b-commerce
php craft plugin/install b2b-commerce

Alternatively, install it from the control panel under Settings → Plugins.

Uninstalling

Uninstalling the plugin intentionally leaves its database tables and their data behind (company accounts, quotes, approvals, order lists, member and department budgets, sales-rep assignments, and more). The install migration is idempotent: if the tables already exist it skips creation and keeps your data, so a later reinstall picks up exactly where you left off — no manual SQL required.

Next step

Continue with the quick start to copy the example templates, configure the plugin settings, and walk through the registration → approval → ordering flow.
