An ecommerce app is more than a smaller version of your website. It needs to make browsing, buying, and tracking orders straightforward for the people who use it—and workable for the team that fulfills them. Before development begins, map your customers, product catalog, payment choices, and order workflows. These decisions help set a clear scope, reveal missing information early, and give your development team a practical foundation for designing and building the app.
Map Your Customers
Start with the customers you want the app to serve, not a list of features you hope to add. Note what they buy, how often they shop, what devices they use, and what makes them leave a purchase unfinished. Review customer questions, support requests, and website analytics if available. These clues can help you prioritize useful features, such as saved carts, reorder options, or clear delivery information.
Sketch the main paths customers will take: discovering a product, comparing options, checking out, and getting help after purchase. Include first-time and returning shoppers, as their needs differ. Decide whether customers can check out as guests, create accounts, or use both options. Keep the first release focused on the most common tasks; each extra path adds design, development, and testing work.
Prepare Your Product Catalog
List the information the app must show for every product. Common fields include the product name, description, price, images, category, stock status, and shipping details. If products come in sizes, colors, bundles, or other variations, document how each option affects price and inventory. Consistent, complete product data makes browsing easier and helps prevent incorrect listings from reaching customers.
Plan how catalog updates will reach the app. Identify the system that holds product and inventory data, who maintains it, and how often changes should appear. Also decide how customers will browse: categories, search, filters, and sorting should match the way they think about your products. Prepare sample records and images before development so the team can test real product cases, including out-of-stock items and complex variations.
Choose Payment and Checkout Rules
Decide which payment methods customers should be able to use, such as credit or debit cards and digital wallets. Confirm which payment provider your business uses or plans to adopt, and check that it supports your needs, sales regions, and existing systems. Your development team can then plan the checkout flow around those choices rather than treating payment as a last-minute add-on.
Write down checkout rules for taxes, shipping costs, discounts, and required customer details. Clarify when the final total appears and what happens if a payment fails or a product becomes unavailable during checkout. Keep the process as simple as your business rules allow. Test the full flow with realistic scenarios, including a declined payment, an applied discount, and an order with different shipping options.
Trace Orders From Start to Finish
Map what happens after a customer taps the order button. Identify how the order reaches your team, how staff confirm and fulfill it, and how inventory changes. Include exceptions such as cancellations, returns, refunds, backorders, and delivery problems. For each step, name the person or system responsible and the information they need. This makes gaps in the process visible before the app has to support them.
Choose the order updates customers should receive and when they should arrive—for example, confirmation, shipment, or pickup readiness. Decide how customers can find order status and contact support if something goes wrong. Wasatch App Works can help turn these requirements into an app plan, but your team should first gather its current processes, system details, and common exceptions so the plan reflects how the business actually operates.
Before development starts, bring your customer journeys, product data, checkout rules, and order steps into one clear plan. Mark open questions and decide which features are essential for launch. A focused outline helps your team estimate work, make informed trade-offs, and avoid preventable changes later.
