Coverage counts what each App Store listing names. Every feature, checked off app by app, is in Shoplist.
See every featureHoldback runs the hire from checkout to return. The customer pays the hire fee at checkout and Shopify saves their card for a deposit, shown up front and taken only if owed. Late? Keep the agreed daily rate for the days late, up to the deposit. Back fine? Release it from It's back. Not returned or lost: keep up to the deposit, as the checkout terms say. Damage goes as an itemised request the customer approves.
Holdout runs A/B tests on your storefront without touching theme files. Describe the change you want, preview both versions, choose the audience and the goal, then launch. It measures conversion rate, revenue per visitor, add-to-cart and order value, and applies the winner as a runtime rule you can roll back at any time. Every test is held to a minimum duration and a calibrated threshold.
- Hire fee at checkout; Shopify saves the card for the deposit, nothing taken
- Not returned or lost: keep up to the deposit the customer agreed to at checkout
- One check when a hire's back: fine, damaged, part missing, not returned or lost
- Late fees at the daily rate agreed at checkout, only when you confirm it's late
- No theme code. Changes run at display time and leave nothing behind.
- Promotion stays locked until duration, volume and data checks all pass.
- Roll back to the original version in one click, at any point in the test.
