A wholesale portal should show and enforce MOQ and case-pack multiples before a buyer submits, instead of fixing broken packs after the order is already in. Week one on Parcel Build is a first working version of those cart rules for known accounts. Flat $5,000/mo. You own the code. See custom software for wholesalers. Start a free 30-day build if that gap is what you want first.
Why silent rounding and after-the-fact emails create returns and margin leakage
When the portal accepts any quantity, someone rounds later or emails the buyer to change the line. Packs break. Margin slips. Returns and credit memos follow. The fix belongs in the cart, with clear rules the buyer can see before submit.
This is cart validation for pack and MOQ. It is not multi-location carts or account price specials.
What week one can cover
Week one can cover per-SKU MOQ, pack multiples, clear error text when a quantity fails, and an exception route to a human when a known account needs a one-off. That is enough to prove the rule path without rebuilding every pack-out flow.
On Parcel Build, week one is a first working version. Flat $5,000/mo. You own the code.
What stays out of month one
Defer every pallet-layer optimizer and a full pack-out redesign. Month one is cart rules buyers can obey, not a warehouse rebuild.
FAQ
Can MOQ differ by customer or only by SKU in month one?
Month one can start with per-SKU MOQ for known accounts. Customer-specific MOQ can follow when that is the next named gap. Week one should not try to encode every exception on day one.
Should invalid quantities be blocked or sent to an exception queue?
Block clear pack and MOQ failures with plain error text. Route true exceptions to a human when a known account needs a one-off. Both can live in week one when scoped tightly.
