YITH Min Max Quantity enforces quantity rules on WooCommerce: minimum order amounts (no single-unit sample orders), maximum caps (wholesale limits), quantity steps (sold only in 6-packs), and group rules per category, tag, or role – the purchasing constraints that B2B catalogs, wholesale operations, and unit-packaged goods require. WooCommerce’s default quantity input accepts anything; real commerce often can’t: a fabric store selling by the meter with minimum cuts, a wholesaler with case minimums, a candy shop selling in dozens – constraints that tools like YITH Dynamic Pricing and Discounts complement on the pricing side. The plugin enforces reality at the cart level with clear customer messaging. Against the WooCommerce family’s merchandising tools and constraint competitors, it’s the dedicated quantity-rule implementation at GPL pricing.
The 1.6x line maintains steady cadence (registry tracks 1.64.0 and 1.57.0 as the verified versions). For B2B and packaged-goods stores, it’s checkout infrastructure.

Comparison with Competitors
YITH Min Max Quantity vs WooCommerce Min/Max Quantities (official)
| Aspect | YITH Min Max Quantity | WooCommerce Min/Max (official) |
|---|---|---|
| Vendor | YITH (GPL) | WooCommerce official |
| Core model | Same (quantity constraints) | Same, plus spend tiers |
| Cart minimums | Value + quantity | Richer spend logic |
| Billing model | GPL license | Official pricing |
| Best for | Standard quantity rules | Advanced spend structures |
Bottom line: The official extension carries deeper cart-spend tiering; YITH covers the core quantity model – minimums, maximums, steps, group rules – at GPL pricing. Spend-tier complexity picks official; quantity discipline picks YITH.
YITH Min Max Quantity vs unenforced minimums
| Aspect | Enforced quantity rules | “Please order 6+” text |
|---|---|---|
| Compliance | Guaranteed at checkout | Ignored constantly |
| Operations | Clean fulfillment | Manual corrections |
| B2B readiness | Real | Aspirational |
Bottom line: Displaying minimums in text doesn’t enforce them – customers order single units anyway, and operations absorb the cleanup. Enforced rules make the catalog behave as the business actually sells.
Recommended Stack – quantity rules pair with pricing tiers: combine with FunnelKit so enforced quantities sit inside the optimized checkout funnel – constraints and conversion on the same order flow.

Frequently Asked Questions
What quantity constraints can I set?
Minimums (must order at least X), maximums (no more than Y), and steps (only in multiples of Z) – individually or combined, per product, category, tag, cart, or user role.
Can wholesale customers have different rules?
Yes – role-based rules give wholesale roles different minimums (case quantities) than retail visitors, serving B2B/B2C hybrid catalogs.
What happens when a cart violates a rule?
Checkout blocks with a clear message explaining the constraint – which product needs what quantity – so customers self-correct instead of support tickets.
Can I enforce a minimum cart value?
Yes – cart-value minimums complement quantity rules: orders under $50 rejected, the pattern minimum-order-fee policies replace.
Do steps work for pack-based goods?
Yes – step rules sell only in multiples: candles in 6-packs, fabric in half-meter increments, the constraint matching how goods actually ship.
