Fixed platform cost
Start with the base subscription and any required white-label or reseller tier. If a capability is essential to the offer, treat its plan cost as fixed even if a cheaper tier technically exists.Variable platform cost
Estimate messaging, phone, email, AI, storage or other metered usage. Use conservative scenarios for heavy clients so one account cannot erase margin.Operating cost
Include onboarding labor, support time, payment processing, account management and cancellations. White-label software does not remove those costs; it only changes where they occur.Price by value and support burden
Do not simply multiply software cost by a markup percentage. The final client price must reflect the business outcome, the service layer and the support promise.Compare cost at the client count you actually expect
A fixed platform fee can look expensive at five clients and inexpensive at fifty. Build a small cost table at several realistic client counts so you can see where the model becomes efficient. Then add high-usage cases for messaging, AI or other metered services. The purpose is not to predict the future perfectly; it is to expose where margin is sensitive.
Also separate optional branding costs from core product costs. A branded app may improve the client experience, but if it adds a large fixed fee, it should earn its place through adoption or commercial value. Do not hide expensive presentation features inside the base package unless the economics support them.
