Start by defining your primary business objective. Are you trying to reduce out-of-stock losses, increase average transaction value, speed up checkout, gather customer data, or reduce staffing pressure? Your answer will guide whether you need endless aisle, self-checkout, digital catalogues, or a blend. Evaluate vendors on integration capabilities with your existing systems, ease of deployment, support quality, and pricing transparency. Request demos and speak with retailers in your category using the solution. Choose a solution you can start small with and scale, rather than committing to a massive upfront installation.
