Installation

Requirements

• CS-Cart or Multi-Vendor 4.17.2 – 4.21.x.
• PHP 7.2.5 – 8.3, as supported by your CS-Cart version.
• Tested on CS-Cart Ultimate 4.17.2, Multi-Vendor 4.17.2 and Multi-Vendor 4.21.2.
• A storefront theme based on Responsive or Nova (the default themes and most third-party themes).
• Recommended: a cron job that runs every hour (see Configuration).

Install

1. Go to Add-ons → Manage add-ons, click the gear button and choose Manual installation.
2. Upload kv_net_terms_credit_limit-<version>.zip and click Upload & install.
3. On the License tab of the settings, enter your license key and save. If you bought the add-on on the CS-Cart Marketplace and entered the license number in Add-ons → Manage add-ons, you can skip this step. Until a key is verified, the add-on works for 14 days (see License).
4. Check the Settings tab: default terms, what happens with orders over the available credit, reminders.
5. Give your first customers net terms: approve an application, add an account in Customers → Net terms & credit, or switch on net terms for a usergroup.

What the installation does:

• creates seven tables (cscart_kv_ntcl_*) for credit accounts, usergroup terms, invoices, payments, applications, a history log and a rate limiter;
• creates the order statuses Awaiting payment (net terms) and Credit review (stock stays reserved, not counted as paid, not counted for vendor payouts); if they exist from an earlier installation, they are reused;
• creates the payment method Net terms (pay by invoice) in Administration → Payment methods (an offline method with the add-on’s PO number form);
• creates six e-mail templates in Design → E-mail templates, the privileges View / Manage net terms and credit accounts and a secret cron key.

No core files are changed.

Upgrade

Upload the new package over the installed add-on (same steps as installing). On the next admin page load the add-on brings its tables, settings and language variables up to date by itself. Accounts, invoices, payments and settings are kept.

Disable

Disabling the add-on (status Off) hides the Net terms payment method and stops new net-terms orders. Existing orders keep their status and data; invoices, payment links and reminders come back when you enable it again. While it is off the add-on does nothing, so payments you receive meanwhile are recorded on the invoices once it is on again (or by changing the order status to Processed after enabling it).

Uninstall

Add-ons → Manage add-ons → B2B Net Terms & Credit Limits → gear → Uninstall:

• removes the add-on’s tables, settings, language variables, e-mail templates, privileges and run marks — including credit accounts, invoices, recorded payments and applications, so export what you need first (accounts, invoices and statements have CSV exports);
• deletes the order statuses if no order uses them; otherwise they stay so those orders keep a valid status;
• deletes the Net terms payment method if no order uses it; otherwise it is disabled and switched to the core purchase order form so those orders keep their payment method.

Orders themselves are never changed or deleted.
