Enforce minimum order quantities and fixed step increments on any product — with a beautiful configurable widget, smart cart validation, and full admin control over every color and text string.

Perfect for wholesale (B2B) stores selling in packs, cases, or with minimum-purchase requirements. Works for retail stores too — restrict MOQ rules to a specific customer group, or apply them globally.

KEY FEATURES

✔ Three rule modes — Pack (step = minimum), Minimum-only (step = 1), or Minimum + Step
✔ PDP hero widget — animated card with title, hint text, stepper, and CTA button
✔ Listing card stamps — quantity constraints visible on category and homepage grids
✔ 4-layer server-side validation — cart.add(), cart.edit(), quick-checkout, and addOrder() all enforce the rule independently
✔ Toast notifications — friendly snap messages when quantity is auto-corrected
✔ Cart violation banners — clear warnings before checkout is allowed
✔ Customer group gate — apply MOQ rules to all customers or a specific group only
✔ Full color control — accent, background, gradient edge, and highlight colors, all CSS-variable-driven with alpha variants auto-computed
✔ Full text control — every label, hint, CTA, toast, error message, cart note, and banner is overridable from the admin panel
✔ Language-file fallback — leave any text field empty to use your store's active language file
✔ Zero hardcoded strings in logic code
✔ Journal3 theme compatible — integrates with Journal3 stepper, quickview, and quick-checkout

COMPATIBLE WITH
• OpenCart 3.0.x
• PHP 7.4+
• Journal3 theme (required for PDP widget and listing stamps)
• Standard OpenCart theme (cart validation and admin module work without Journal3)
• Multi-store installations
