Limit Once prevents second-time purchases of chosen products. Select the items to cap, and the app enforces a “one per customer” rule during checkout—including express options—so repeat attempts are declined with a clear message. Setup takes minutes in Shopify, and you can turn the rule on or off per product whenever you need.

• Per-product “one per customer” rule at checkout
• Blocks repeat orders across standard and express checkouts
• Shows a clear message when a repeat order is blocked

Wandelic RFQ helps B2B buyers submit SKU and quantity CSVs as quote requests. Each line is checked for SKU issues, quantity errors, MOQ, case pack, sellability, and stock warnings before submission. Merchants can review RFQs, fix or remove lines, apply company catalog prices, create draft orders, and send Shopify invoice emails with quote PDF links.

• Upload SKU CSVs and catch bad rows
• Review MOQ, case pack, and stock warnings
• Create draft orders with quote links
