What drives the price
Scope. Number of objects (contacts, companies, deals, quotes, projects), screens and roles.
Integrations. Each connection (email, calendar, accounting, website forms, telephony) has to be designed and tested.
Data migration. Clean exports are quick; scattered spreadsheets take longer.
AI features. Agents that draft follow-ups or summarise threads add design work, plus a usage cost billed by the model provider.
Typical ranges
Freelancer or small studio with a tight scope: a few thousand euros. Agency with a long discovery phase: tens of thousands. Enterprise integrator: often more. At Deepthix, projects start at EUR 4,500 excl. VAT for an agreed scope, paid once.
Compare over three years
Add up the subscription CRM cost over 36 months (users × price × 36, plus add-ons) and compare it with the custom project, paid once. Remember who owns the code and the data at the end. See our pricing.
Questions to ask every provider
What exactly is in scope? Who owns the code? Where is it hosted? What happens if I stop working with you? How are changes priced after delivery?
Frequently asked questions
Is a custom CRM more expensive than HubSpot or Salesforce?
Over one year with few users, usually not cheaper. Over three years with a team, a custom CRM often costs less and remains yours. See HubSpot alternative.
