Get paid your way: three preorder payment structures
| Preorder payment option | When to use it |
|---|---|
| Full payment upfront | Collect the entire order value at preorder. Best for confirmed inventory on the way — maximum cash flow and zero follow-up billing. |
| Partial deposit | Collect a deposit now and the balance later. Lowers the commitment barrier on higher-priced items while still qualifying real buying intent. |
| Discount-based incentive | Offer a discount for ordering before stock arrives. Best for launches where you want to reward early demand and forecast volume. |

One app for the whole demand loop
Preorders, restock alerts via email/SMS/web push, demand capture forms, and analytics in a single app — no second subscription, no duplicated theme code.
Plan smarter with demand data
Preorder and signup insights show which products customers want most, informing inventory buys, launch timing, and marketing before stock even arrives.

Does Back in Stock charge per-preorder fees?
No. Back in Stock plans are flat — preorders are unlimited on every paid plan, with no per-preorder transaction or overage fees. Several competing preorder apps automatically bill $0.10–$0.25 per preorder above their plan caps.
Can customers pay a partial deposit on a preorder?
Yes. Back in Stock supports full payment, partial deposit, and discount-based preorder incentives, so you can choose the payment structure that fits each product launch.
Why combine preorders with back-in-stock alerts?
They are two halves of the same demand loop. When a product sells out, restock alerts capture and recover the demand; when new inventory or a new product is on the way, preorders convert that demand immediately and improve cash flow. Back in Stock covers both — plus the demand analytics to plan inventory — in one app, so you don't need two subscriptions.
