Prebuy connects your supply chain to Shopify, so you can sell inventory in production, in transit, or in the warehouse — automatically.
The preorder and pipeline-inventory layer for Shopify. Automatic from PO to doorstep.

Most brands cherry-pick which products go on preorder. The brands running on Prebuy don’t.
They plug their entire supply chain into prebuy. Stock flips to preorder automatically when inventory hits zero. It flips back to standard when stock lands. No manual switches. No decisions to make per SKU. No campaigns to set up in panic at 11pm before a drop.
The supply chain is the source of truth. Prebuy is the layer that listens.
Product flips to preorder automatically. The customer sees an expected ship date drawn from your supply chain, not invented in the storefront.
A campaign is created. Shipments draw down from it. The earliest possible ship date is calculated from the soonest shipment — not the latest, not the average, not the optimistic one.
Orders release in FIFO order. Inventory moves out of the preorder pool. Klaviyo fires the dispatch event. Your CX team finds out at the same time the customer does.
Stock lands, orders release. Everything between purchase order and warehouse receipt is the system’s responsibility — not a spreadsheet’s.
POs, in-transit shipments, and pipeline stock sync into Shopify — at the variant level, with reserves and buffers honoured against the actual landing window. No theme rebuild, no re-platforming.
Open the window early. Customers see live, honest EDDs on the PDP. Prebuy holds the campaign state — partials, queues, waitlists — while you focus on the merchandise.
FIFO allocation against incoming stock. Balance capture on schedule. Klaviyo flows fired on every state change. Partial PO arrivals release queued orders automatically.
Six parts of one system, calibrated for fashion ops. No bolt-on plugins. No surprise behaviour on the live storefront. The machinery your ops lead would have built — if they had six months and a back-end team.
Your purchase orders, your shipments, your dates. Prebuy mirrors your supply chain — variant by variant, shipment by shipment. We don’t ask you to learn a new model. We use yours.
The dispatch date a customer sees is the same date your ops team commits to. EDD updates propagate to Klaviyo, the PDP, and the order confirmation automatically.
FIFO against incoming stock. Partial PO arrivals release queued orders. No double-allocation, no “where is my order” tickets to answer by hand.
Every state transition fires a typed event — old date, new date, order metadata. Build flows on top of fact, not webhooks held together with hope.
Campaigns respect market location, currency, and selling-plan availability. One campaign covers the catalogue — region rules apply themselves.
One snippet, no rebuild. Works across Dawn, Horizon, and the bespoke front-ends premium fashion brands actually run.
Revenue starts when the PO is placed, not when it lands.
Every premium fashion brand lives with it — the dead weeks between a PO placed and stock landed, when capital is committed but revenue can’t start. You’ve paid for the goods. You can’t sell them. The gap is where margin goes to wait.
Prebuy closes the gap. Sell from the moment the PO is raised, not the day the boxes arrive.
Everything you need from day one. No hidden fees, no feature gates. 30-day free trial on every plan — no credit card required.
A 25-minute call. Bring your most painful preorder of the last twelve months. We’ll show you the mechanism that closes it.
