Scope custom software around the first outcome that must become possible, not a feature list. Determine who must do what, with which data and constraints, so the budget and timeline rest on a defensible scope.
Describe one complete action
Start with the primary user and one real occurrence. What triggers the journey? Which information is needed? Which decision must be made? What result confirms the work is complete? This reveals more than an inventory of screens.
Make risks visible early
List roles, sensitive data, systems to connect, difficult rules, and non-negotiable dates. An integration or migration can change the journey, testing, and team responsibilities.
Choose what waits
A strong first scope completes one journey without demanding every variation. Secondary reporting and deep customization can enter a later phase with a clear review condition.
Then prepare a custom software estimate and a realistic timeline. You can also scope a software development project in Quebec with Project Factory.
