If you are a growing Shopify brand, having demand is only half the problem. The harder part is being able to sell when that demand arrives.

You can start generating demand for a product before the first production run is ready. A limited collection can sell faster than you expected. A popular SKU can go out of stock while your next shipment is still weeks away. In all these cases, customers want to buy, but you don't have the inventory ready to sell.

For smaller stores, that might mean a few missed orders. At scale, the consequences can be much larger. Marketing has already driven traffic to the product, customer support has to deal with availability questions, fulfillment teams are working around changing inventory and the business may have significant capital tied up in its next production run.

This is where a preorder strategy can make sense. It may not be useful for every product or every Shopify merchant, but when you have customers ready to buy and the product isn't available yet, preorders give you another way to capture those sales.

How much inventory should you order?

When you're selling an established product, historical sales data can give you a reasonable idea of what to order next. It gets harder when you're launching something new.

You don't have sales data from previous campaigns for the product. You might have customer research, campaign performance, waitlist signups or other signals, but you are still making an educated guess about how many people will actually buy. And getting that number wrong can be expensive.

When you order too much, you have capital tied up in inventory that may take months to sell. When you order too little, you have customers ready to buy but nothing available to sell them.

Demand forecasting can help you plan for a new launch or promotion, but when there's no sales history, there will always be some uncertainty. A preorder gives you another signal to work with: an actual customer placing an order.

Preorders can help you test demand before committing to more inventory

But not all demand signals are equally useful. A survey can tell you what customers think. A waitlist can tell you that they want to hear more. But a preorder tells you that they are willing to buy.

That makes preorders particularly useful for new products, limited collections and products with longer production timelines. Shopify also describes preorders as a way to secure sales before a product is available and use customer interest to help inform inventory decisions.

For example, if you are preparing a new product and aren't sure whether to produce 50 units or 5,000, opening a preorder window can give you a clearer picture of how many customers are actually willing to buy before making the next inventory decision.

It is still a forecast, but now you have actual orders to help inform it.

You don't always have to stop selling when inventory runs out

Preorders aren't only useful for new product launches. A product can already have strong demand and still run out of stock. Your next shipment might be on its way, but customers are still landing on the product page today. At that point, you have a few options.

You can simply show "out of stock." You can collect email or SMS signups and notify customers when the product returns. Or if you have a reasonable fulfillment timeline, you can continue accepting orders as preorders. Apps like STOQ can help Shopify merchants manage both preorder and back-in-stock experiences.

The right option depends on the product and the business. But the important thing is to recognize that inventory being unavailable doesn't necessarily mean demand has disappeared.

For a growing brand, this can be especially important when marketing is already driving customers to a product. You have already paid to create that demand. Sending those customers to a dead-end product page means giving up the opportunity to capture it.

A preorder is not just a button on your product page

This is where preorder strategies can become more complicated for larger brands. Setting up a preorder on the storefront is relatively simple. The harder part is everything that happens after the customer places the order.

When will the product ship? What happens if production is delayed? What happens when a customer buys a preorder product together with an in-stock product? Can your warehouse and fulfillment team handle those orders correctly? What does the customer support team tell someone who wants to know where their order is?

These questions need to be answered before the preorder campaign goes live.

That accountability doesn't stop when the order is placed. Customers expect the timeline they were promised and if it changes, they expect to be told before they have to ask. That's why a preorder strategy needs to be treated as an operational decision as well. The customer experience has to work from the product page through fulfillment and post-purchase communication.

So, if you're evaluating a Shopify preorder app, look beyond the storefront button and consider how it fits into fulfillment, payments, customer communication and the rest of your stack.

So, when should you consider a preorder strategy?

There isn't a stage where every brand suddenly needs a preorder strategy.

They are worth considering when you are dealing with situations such as:

●       Launching a new product with little historical sales data

●       Producing products with significant upfront costs

●       Working with long manufacturing lead times

●       Running limited or seasonal product drops

●       Expecting demand to exceed your initial inventory

●       Regularly selling out of high-demand products

●       Having inventory on the way but not available to ship yet

It may not make sense when inventory is readily available, demand is highly predictable, or your fulfillment operation isn't equipped to handle delayed orders. The goal shouldn’t be to replace inventory planning with preorders.

It's to have another option when demand and inventory don't arrive at the same time.

For some Shopify brands, that can mean getting a better understanding of demand before committing to a larger production run. For others, it can mean continuing to capture sales while the next shipment is on its way.

And as your brand grows, that distinction becomes more important. You will never have perfect inventory at every moment. What matters is having a plan for what happens when customers want to buy and your inventory isn't ready. A Shopify preorder can be one of those options.
