Custom CRM vs Salesforce and HubSpot: when building wins

We build custom CRMs for a living, and we still tell most small teams to start with an off-the-shelf tool. The decision usually comes down to three things: how unusual your process is, how many people need a seat, and whether the CRM is a cost centre or part of what you sell.

Our recommendation

Buy Salesforce or HubSpot if your sales process is close to standard and you have fewer than a few dozen users. Build a custom CRM when your process or data model no longer fits, when per-seat licences across a large team have passed the cost of building and running your own, or when the CRM is part of the product you sell.

Choose Custom CRM if…

  • Your process has steps, entities or approvals that you keep forcing into custom objects.
  • You have a large team and the annual licence bill keeps climbing.
  • The CRM is part of the product you sell to your own customers.
  • You want AI features trained and evaluated on your own pipeline history.
  • Data residency rules mean customer data must stay in your own cloud.

Choose Salesforce or HubSpot if…

  • Your sales process looks like most sales processes.
  • You have a small team and need something working this week.
  • You rely on a marketplace of ready-made integrations.
  • Nobody in the company will own a piece of software after launch.

The licence maths

At list prices checked in October 2026, Salesforce Sales Cloud has a free suite for up to two users, Starter Suite at $25 and Pro Suite at $100 per user per month. On 3 September 2026 Salesforce introduced Core at $195, Advanced at $395 and Max at $550 per user per month, billed annually, with AI credits bundled in. Its pricing page now lists these in place of Enterprise and Unlimited, and existing customers keep their current pricing. Agentforce for Sales is an add-on from $125 per user per month. HubSpot Sales Hub is free for up to two users; Professional is $90 per seat per month billed annually, or $100 monthly, plus a $1,500 onboarding fee, and Enterprise is $150 per seat plus $3,500 onboarding.

Fifty users on Salesforce Core is $117,000 a year at list price before add-ons, and fifty HubSpot Sales Hub Professional seats are $54,000 a year plus onboarding. Those numbers grow with every hire and every price rise. A custom CRM costs more up front and less every year after, and the crossover point depends on team size, complexity and how much you would otherwise spend on configuration and consultants. Vendor prices change, so check their pricing pages before you decide.

Fit is the bigger cost

The hidden cost of an off-the-shelf CRM is not the licence. It is the workarounds: the spreadsheet beside it, the fields nobody fills in, the report that needs an export and a pivot table every Monday. When a tool fits, those disappear. When it does not, they multiply.

A custom CRM starts from your entities and workflows. If you sell through partners, quote complex configurations, or run service and sales from one record, the data model can say so directly instead of through layers of customisation.

AI changes the equation

Both Salesforce and HubSpot now include some AI in their paid editions and sell more as add-ons or usage credits. They work well inside the vendor's model of a CRM. A custom AI-native CRM can do things the vendor's AI cannot: score leads against your own closed-won history, summarise calls in your terminology, and draft follow-ups in your house style, all evaluated on your data and run in your cloud.

What a custom build involves

We build custom CRMs on Java, Spring Boot and MySQL with a React front end: contacts, pipeline, roles, audit trails, reports and the integrations you need. Data migration from your current CRM is scoped as its own deliverable, with a rehearsal run and a way back. You own the code and the infrastructure, so you can bring maintenance in-house at any point.

Questions

What does Salesforce Sales Cloud cost per user in 2026?

At list price, from $0 for the Free Suite (up to two users) to $25 for Starter Suite, $100 for Pro Suite, $195 for Core, $395 for Advanced and $550 for Max, per user per month, billed annually. Agentforce for Sales is an add-on from $125 per user per month. Existing customers on Enterprise or Unlimited keep their pricing. Prices change, so check Salesforce's pricing page.

Is a custom CRM cheaper than Salesforce?

Over a few years, often yes for large teams with unusual processes, and rarely for small teams with standard ones. The build costs more up front; the licence saving accumulates every year after.

How long does a custom CRM take to build?

A focused first release usually takes a few months, depending on workflows, integrations and data migration. Scope and date are agreed before work starts.

Can we migrate from Salesforce or HubSpot to a custom CRM?

Yes. Both offer data export. We map and clean the data, rehearse the migration against a copy and plan a cut-over with a way back.

Can we keep Salesforce and build only what is missing?

Yes. Sometimes the right answer is a custom portal, workflow or AI feature that talks to Salesforce or HubSpot through their APIs.

Can we build our own CRM with AI tools instead?

You can build a convincing prototype that way. Running it as a system of record is different work: permissions, audit trails, backups, migrations, security fixes and someone on call. A prototype is a good specification for a proper build.
