Test a multi-product store before launch with practical checks for product pages, categories, £ pricing, stock, mobile checkout and a focused first promotion.
A multi-product store does not need a huge catalogue before its first launch test. It needs a focused group of products, clear routes between them, accurate prices and availability, and a buyer journey you can complete on a phone. This guide shows how to check those pieces before widening promotion.
The aim is not to prove that a store will succeed. It is to find avoidable gaps, make one small test easier to interpret and decide what evidence to gather next.
Use the free assessment to review your product range, categories, pricing, stock and launch test. You will get an evidence map and a practical next action.
A useful pre-launch test checks whether a buyer can understand the range, find a suitable item, compare options, see the full price and delivery information, and complete the route to an order. It also checks whether you can supply what the store promises.
You do not have to switch on every product or spend heavily on advertising to learn. Start with a defined group, rehearse the journey, and use a small promotion or direct customer conversation to investigate one assumption at a time. If you are still choosing which products belong together, first read our guide to planning an ecommerce product range.
Pick a manageable set that serves a recognisable buyer or use. One lead product, a few useful variants and one relevant companion item can be easier to test than a broad catalogue of unrelated products. The exact number depends on the products, your capacity and the evidence you already have.
Write down why each item is in the first group. It might solve the same problem, suit the same occasion, or let a buyer choose a size, colour or bundle. If you cannot explain the relationship in a sentence, consider separating the item from the first test. This is a starting hypothesis, not a rule that every product must fit one category.
Keep evidence separate from opinion. A customer question, supplier confirmation or completed test order has a source and date. A preference or forecast is an assumption to check. The Multi Product Range Planner can help you structure product roles and category choices.
Organise the store around the words and decisions buyers use. Ask someone unfamiliar with the catalogue to find an item, compare two options and explain what the category names mean. Notice where they hesitate, open the wrong section or miss a variant.
Use category names that distinguish products without making shoppers learn your internal stock language. Keep colour, size or material choices with the product when they are variants of the same item. If a choice changes the use, contents or price substantially, show that difference clearly before it reaches the basket.
A product grid is not a substitute for a usable route. Test the route from category to item, item to options, and options to basket on both a laptop and a phone.
Check the product name, photographs, dimensions or specifications, materials, included items, available options, price and availability. Confirm that the page describes the item a customer will receive, not only the way you refer to it in your stock sheet.
Look for differences that could create confusion: a size shown in one unit on one page and another unit elsewhere, a bundle photograph that does not match its contents, or a delivery estimate that changes across the product and checkout pages. Assign someone to compare a small sample of pages against the supplier or product record.
For physical goods, product suitability and safety are separate from page quality. Check the rules that apply to the products and your role in the supply chain. The UK Government’s product safety advice for businesses explains responsibilities for businesses that make, import, distribute or sell consumer products.
For each launch product, write down the customer price in £ and the costs that change when an order is placed. Depending on your model, include the product or production cost, packaging, delivery you cover, payment or marketplace fees, fulfilment and a realistic allowance for replacements or returns.
| Illustrative item | Customer price | Example variable costs | Contribution before overheads |
|---|---|---|---|
| Travel mug | £24.00 | £14.50 | £9.50 |
| Canvas tote | £32.00 | £21.10 | £10.90 |
| Gift set | £48.00 | £31.70 | £16.30 |
These figures are illustrative, not a recommendation or forecast. Contribution is not net profit. The example excludes overheads, staff time, tax and returns, and it does not specify a VAT basis. For your own store, make the VAT treatment and price basis consistent across the calculation. Check that the total price and delivery costs are presented clearly to customers; the Government’s online selling guidance sets out information businesses need to give before an order is placed.
For a deeper comparison of product mix, contribution and stock cover, use the Multi Product Store planning guide and its companion simulator.
Check which units are actually sellable, what is reserved, and how quickly you can replace stock. If a supplier fulfils the order, confirm the current lead time, dispatch route, service limits and the person to contact if the order is delayed or damaged.
Decide what the store should show when a colour or size is unavailable. Avoid leaving an option visible as purchasable if you cannot support the delivery promise. A short stock review can include sellable quantity, replenishment lead time, minimum order quantity and the date each figure was last confirmed.
Start at the route a real visitor would use, not the admin screen. Find a category, open a product, choose an option, add it to the basket, review delivery and total price, and go as far as a safe test checkout without placing a real paid order.
Check that every important control has a clear label, visible focus, sufficient contrast and a useful error message. Try the route with a keyboard and at a narrow screen width. Notice whether a buyer can change an option or correct an order without losing their place. The Government’s online selling guidance also notes that customers should be able to see payment and delivery options and correct order errors.
Choose the question before choosing the promotion. For example: do new visitors understand which gift set suits a particular occasion, or can customers find the refill option without contacting support? Keep the audience, product group, channel, time period and spending limit small enough to learn from.
Choose one primary signal connected to the question. It could be a qualified product-page visit, a completed order, a variant choice, a customer question or a checkout error. Decide what you will record and when you will review it. If several things change at once, the result may be difficult to explain.
After the test, record the source and date of the evidence, what happened, and whether you will repeat, revise or pause. A small test is useful even when it shows that a product page needs clearer details or that a supplier promise needs another check.
Review seven areas in the assessment, then use the evidence map to choose what to verify before your next launch test.
The app reflects the answers you choose. A stronger result means you have more of the evidence you selected in place; it does not verify that evidence or predict demand, sales or profit. Read the individual areas as well as the overall band. One weak stock or delivery check can matter more to a real buyer than several strong planning answers.
Use the suggested next action to make your next check specific. Compare the result with a dated supplier record, a test order, a customer conversation or an observed mobile journey. If the evidence changes, update your plan and take the assessment again.
There is no universal number. Choose a group you can explain, keep accurate and fulfil. A small related selection may be easier to review than a full catalogue, but the right scope depends on the products, customer choice and your operating capacity.
You can plan a limited test around the products and routes you can support. Make unavailable items clear, do not imply that stock or delivery is ready when it is not, and check product information and applicable requirements before offering items to customers.
Choose a signal that answers your question. A product-page visit may help test discovery, while a completed order or support question can reveal something different. Record the audience, product, date and channel so the observation has context.
No. The assessment organises your answers and suggests a next step. It does not verify customer demand, predict sales, calculate profit or guarantee a business outcome.
A good pre-launch review connects what a customer sees with what you can actually supply. Keep the first range clear, check the details and order route, and make the promotion small enough to review honestly. When you know which evidence is missing, improve that part before widening the test.
Use the free assessment to organise your answers into evidence, risk and a focused next test. If you want help turning the findings into a store plan, compare MLFG’s setup options or contact the team.
