Cost & Timeline
How much does it cost?
Custom applications are the most variable service we offer in terms of price, since scope ranges from a simple internal tool to a multi-role production platform. We scope every project individually based on the required architecture, integrations, and user roles, and provide a fixed quote before work begins. Realistic custom software budgets typically start well above a basic website.
How long does it take?
Custom applications generally take 8–16+ weeks depending on the number of user roles, integrations, and how much of the system needs to be built from scratch versus using existing infrastructure.
