Wholesale — tiered pricing by customer group for OpenCart 2.3, 3.x and 4.x

Wholesale for OpenCart 2.3, 3.x and 4.x is a module for stores that sell to both retail and wholesale buyers at the same time. It adds what’s missing from OpenCart’s core: separate prices for customer groups by flexible rules, a minimum order amount, a quantity step, and selling in packs of N units.

Wholesale pricing by rule

A rule is described once and applied to everything it covers: a specific product, a category, a manufacturer, or the whole catalogue — separately for each customer group. Discount type is a fixed price, a percentage, or an amount off. A minimum quantity can be set for each rule, letting the price work as a tiered price: one price from 10 units, another from 50.

The key technical decision: rules are materialised into OpenCart’s native discount table, so the wholesale price shows up correctly in the catalogue, cart, totals, order and API — with no core changes and no theme conflicts. Percentage discounts are stored as a percentage, not pre-calculated, so they stay correct after the base price changes. Rows created by the module are marked separately — the module never touches or overwrites your own promotions.

Minimum order amount

Set globally, or separately for each customer group. The buyer sees a clear message in the cart about how much more they need to add, and checkout is blocked until the condition is met — on the cart page, at checkout, and at order confirmation, so it can’t be bypassed with a direct request.

Quantity step and packaging

Minimum quantity and step are set globally or for an individual product: if the step is 5, the buyer can’t put 3 or 7 units in the cart — the quantity adjusts automatically, with a message about it. Pack mode shows on the product card how many units are in a pack, and recalculates the price correctly.

Admin area

A dedicated screen with a rule list: filters, pagination, bulk actions (enable, disable, delete), CSV export. Rules recalculate automatically — including after saving a product card, after import, and on a schedule via cron.

Free version and Pro

Free: wholesale pricing on individual products (up to 5 active rules), a fixed price, a percentage or an amount off, a store-wide minimum order amount with checkout blocking, a quantity step and minimum quantity, automatic recalculation after saving a product and on a schedule.

Pro: rules by category, manufacturer and across the whole catalogue; quantity thresholds (one price from 10, another from 50); no limit on the number of rules; a separate minimum amount for each customer group; selling in packs of N units; exporting the rule list to CSV.

Trial — only on your click. A fresh install switches nothing on by itself: the module works as the free version until you click “Try Pro” yourself. Then a genuine 7-day key arrives at your e-mail. No card, no auto-renewal: once the week is up, the free part just keeps working, and prices already generated stay in place.

Version history

• 1.1.0 (OpenCart 3.x) — the OpenCart 3.0.x build moved to server-side licensing. Previously the trial Pro period switched on by itself right after installation, and any non-empty string counted as a key — now a fresh install is a clean free version, and the 7-day trial only starts on a “Try Pro” click; the key is confirmed by the server with a 14-day allowance in case it’s unreachable. Saving settings no longer wipes an activated key. The main fix: the Free/Pro boundary now applies to the prices themselves too — previously category rules and quantity thresholds created during a trial stayed in the price tables and the store kept selling at them even after the trial ended. Rules aren’t deleted: they simply stop applying and switch back on once a key is entered.
• 1.0.0 (OpenCart 2.3) — a separate build for OpenCart 2.3.0.x: the same wholesale rules, minimum order amount, quantity step and packaging. Since OpenCart 2.3 has no controller events, the cart and checkout checks are inserted via a modification (ocmod) — after installation you need to click “Refresh” in Extensions → Modifications; pricing itself works without that. Files are uploaded to the store root manually: the standard 2.3 Installer only works over FTP.
• 1.1.0 (04.08.2026) — the licence is verified on the CatCode server, the trial only starts on a click (previously it switched on by itself after installation). Fixed price recalculation on OpenCart 4.0.x — it didn’t work at all before, due to a difference in the discount table structure between 4.0 and 4.1. Fixed admin events that didn’t fire on 4.0, and duplication of generated rows when a product card was saved again.
• 1.0.0 (28.07.2026) — first release.
