Preorder and Channel-Specific Stock Rules
The Opportunity
An app for merchants who need to sell out-of-stock items on some channels but not others. It lets them control preorders, invoices, and POS overrides without manual inventory hacks.
"Merchants need selective control over the 'continue selling when out of stock' behavior, but Shopify lacks channel-specific rules and forces manual workarounds."
Market Validation
Detailed Analysis
Proposed Solution
Offer rules that enable or disable overselling by sales channel, customer type, or order source, with separate behavior for online store, POS, draft invoices, and staff orders.
Target Audience
Merchants doing preorders, made-to-order, B2B invoicing, or omnichannel sales
Competitive Landscape
Preorderly, Back in Stock apps, oversell/preorder apps, and inventory rule apps
Implementation Notes
Add channel-aware rules tied to product metafields or tags, enforce availability logic in cart and checkout, and expose admin controls for staff/POS/invoice exceptions; include alerts when oversell rules are active and inventory is zero.
Evidence from Merchants
Real quotes from Shopify community forums
"I just want to make sure that I am going about this in the easiest way possible."
"It would be great if there were a function to select which channels have access to the items marked as ‘continue selling when out of stock.’"
"We need to manually adjust our inventory so that they can complete the purchase online."
"This would be a very helpful feature in an upcoming update!"
Key Pain Points
Need for better inventory management when combining on-hand stock with POD fulfillment.
