We had a different kind of problem. People were visiting the store, adding products to their carts, and then disappearing before they finished the order. We had tried a few apps and made changes here and there, but nothing really seemed to solve the bigger issue. The team went through the shopping experience with us and pointed out things we hadn't really noticed ourselves. They cleaned up the cart and checkout flow, made the mobile experience much smoother, and helped us make the store feel easier to shop. I’m not going to pretend we fixed everything overnight, but it finally feels like the store is helping the sale instead of getting in the way of it.
Ethan Parker
Founder of Elite Academy
The mobile experience is probably my favourite part of the new site. We had spent a lot of time making sure the desktop version looked right, and the team kept pushing us to think about how everything would actually feel on a phone too. They were right. The navigation is clean, the interactions feel natural, and everything we’ve tested so far works exactly as it should. They also went through the links, forms, integrations, and other details more than once before launch, which I really appreciated. And even after going live, we could still reach out when something came up. The whole process felt friendly, organised, and surprisingly straightforward.
James Whitmore
Head of Marketing of Lumen Outdoor
We had a pretty specific idea of what we wanted our website to become, but I wasn’t sure how easily we could explain all of it to a development team. There were quite a few moving parts, and we were working toward a deadline, so I expected a few things to get lost along the way. That never really happened. They understood what we were trying to achieve, kept us updated throughout the process, and got everything ready within the agreed timeline. The final site feels much easier to navigate, works beautifully on mobile, and is noticeably smoother for our customers. It was a huge relief seeing the original idea actually turn into the website we had in mind.

Why Businesses Trust Us With Pre-Order Setups
Getting payment timing or cart handling wrong means bad cash flow or a confusing checkout, so the setup has to match how you actually sell. These are the habits we bring to every project.
App checked first
We tell you upfront if a pre-order app already covers your payment model and cart needs.
Payment model matched to your cash flow
Charge now, later, a deposit, or installments, chosen for what actually fits your business, not a default.
Mixed carts handled cleanly
Split fulfillment, separate orders, or held shipments, configured to avoid double shipping charges.
Tested before it's live
Sandbox testing with real payment and cart scenarios before your live store is touched.
Clear on what's included
You know exactly which payment model, cart rules, and integrations are covered before development starts.
Built to be maintained
Documentation and an optional retainer so the setup keeps working as Shopify's checkout evolves.

Who it's for
Stores selling before stock arrives
You want to take orders ahead of a restock or new launch and need the payment timing and messaging set up correctly.
Businesses choosing a payment model
You're not sure whether to charge upfront, defer the charge, take a deposit, or offer installments, and want the tradeoffs explained for your case.
Stores with mixed pre-order and in-stock carts
Customers can buy pre-order and in-stock items together, and you need to avoid double shipping charges or confusing split shipments.
Businesses needing backorder rules
You want a clear rule for what happens when stock runs out, rather than the default out-of-stock behavior.
Stores syncing pre-order demand with 3PL or ERP
Your 3PL or ERP needs visibility into pre-order volume ahead of the actual stock arriving, not just live inventory.
Not a fit for
A pre-order app already covers your payment model and mixed-cart handling. We'll tell you that upfront instead of building something custom you don't need.
You need the broader order routing or warehouse assignment logic rather than pre-order and backorder rules specifically. Our Shopify Order Management System service covers that.
Your pre-order demand needs to feed into a 3PL's inbound planning or an ERP's purchasing process. Our Shopify 3PL Integration or ERP Integration services cover those.
You're not on Shopify. This setup is Shopify-specific, and other platforms would need to be scoped separately.

12FAQ
Frequently Asked Questions
Straight answers on Shopify pre-order setup, payment models, and mixed carts.
How to set up pre order on Shopify?
It starts with choosing a payment model, charge now, defer the charge, take a deposit, or offer installments on Plus, then configuring product availability, messaging, and estimated ship dates so customers know exactly what they're buying.
How do I take pre orders without overselling?
We set a pre-order-specific inventory count separate from your regular stock, or a hard cap on quantity, so Shopify's continue-selling-when-out-of-stock setting doesn't let pre-order volume run past what you can actually fulfill.
How do pre-order payments work (charge now or later)?
Charge now takes full payment at checkout with fulfillment held until stock arrives. Charge later uses a vaulted card through Shopify Payments or PayPal to collect payment when the item ships, which avoids the 7-day standard authorization hold limit. Deposits collect part now and the balance later.
Can I mix pre-order and in-stock items in one cart?
Yes, but it needs a deliberate choice: split into two shipments on one order, force two separate checkouts, hold everything until the pre-order item ships, or block mixed carts entirely. Left unconfigured, mixed shipping profiles often trigger a second shipping charge customers don't expect.
Can you add backorder rules when stock runs out?
Yes. We set rules for what happens automatically when stock hits zero, continue selling with an estimated ship date, cap quantity at a safe pre-order buffer, or switch to a waitlist, rather than leaving it at Shopify's default.
How do pre orders sync with my 3PL or ERP?
We push pre-order volume to your 3PL or ERP ahead of the physical stock arriving, so their inbound planning or purchasing reflects real demand instead of only what's already on hand.
Can customers see estimated ship dates?
Yes, we display an estimated ship date on the product page and in order confirmation and status emails, pulled from your actual restock or production timeline rather than a generic message.
How much does custom pre-order setup cost?
Projects typically start from $1,299 for a single payment model with standard cart handling, and scale up with multiple payment models, complex mixed-cart rules, or 3PL and ERP sync. You get a fixed quote after reviewing your setup.
