How much does it cost to build a custom CRM?
A custom CRM typically runs from the mid five figures for a focused system to six figures for a multi-team platform with integrations. The question isn't only the build price — it's whether owning a CRM that fits beats paying per-seat for Salesforce or HubSpot forever, especially as you add users.
Bands follow general custom-software pricing (2026 market pricing guides); per-seat SaaS compounds with every user added.
What a custom CRM costs.
- Focused CRM — ~£25k–£60k for your core pipeline and contacts, fitted to your process.
- Multi-team platform — £60k–£150k+ with integrations, automation and reporting.
- Plus maintenance — ~15–20% of build/year to keep it current.
- No per-seat fees — add users without adding cost.
When owning beats renting.
Salesforce and HubSpot are excellent and right for many. Custom wins when your sales or service process is unusual, when per-seat fees punish your growth, or when you're paying for features you don't use and missing one you need. Past enough seats, a fitted CRM you own costs less than renting one you bend to fit.
Common questions.
How much does it cost to build a custom CRM?
Typically mid five figures for a focused system (~£25k–£60k) and six figures for a multi-team platform with integrations. Maintenance runs about 15–20% of the build per year, and there are no per-seat fees.
Is a custom CRM cheaper than Salesforce or HubSpot?
Over time it can be, especially at scale — per-seat SaaS compounds with every user, while a build is paid for. Custom wins when your process is unusual, you're paying for unused features, or seat fees punish growth.
When should I build a custom CRM instead of buying one?
When no off-the-shelf CRM fits your sales or service process without heavy workarounds, when per-seat costs are climbing, or when the CRM is central to how you compete and you want to own it.
What drives the cost of a custom CRM?
Scope (pipelines, teams, automation), integrations with your other systems, reporting needs, and data migration. The more it does and connects to, the higher the band.
Will I own a custom CRM outright?
Yes — with the right contract you own the code and data and can take it anywhere, unlike a SaaS CRM you rent per seat. See our who-owns-the-IP page.
Can a custom CRM integrate with my other tools?
Yes — integration is usually a core reason to build one, so your CRM shares data with finance, support and ops instead of being another island.
