Replacing HubSpot with custom software eliminates per-seat costs across CRM, Marketing, and Service hubs, gives you software that fits your exact sales and marketing process, and removes vendor lock-in. For a UK SME with 50 users across HubSpot CRM and Marketing Hub at 50 per seat per month, the annual subscription is 30,000. Custom software costing 60,000 to build, with 10,000 annual maintenance, pays for itself in approximately 24 to 30 months and saves 20,000 or more every year after.
We help UK SMEs replace HubSpot with custom CRM and marketing software. See our dedicated HubSpot replacement page for a detailed comparison.
Why Do UK SMEs Replace HubSpot?
The common triggers for leaving HubSpot:
- Cost scaling: HubSpot charges per seat and per hub. A team using CRM, Marketing, and Service Hubs at 50 users pays 30,000 to 90,000 per year depending on tiers. Price increases compound this. See our guide on hidden SaaS costs.
- Feature bloat: HubSpot bundles many features across marketing, sales, and service. Many SMEs use 30 percent of what they pay for. Custom software includes only what you need.
- Process mismatch: HubSpot assumes a standard inbound marketing and sales process. If your process differs, you adapt to HubSpot or pay for customisation.
- Tier lock-in: Key features (custom reporting, automation, A/B testing) are locked behind higher tiers. Moving between tiers changes your cost significantly.
- Integration costs: Connecting HubSpot to custom or legacy systems often requires paid integrations or middleware.
How Much Can You Save by Replacing HubSpot?
The cost comparison for a 50-user team using CRM and Marketing Hub over five years:
HubSpot (Professional tier, approximately 50 per seat combined):
- Annual subscription: 30,000
- Year 5 (with 7 percent annual increases): approximately 39,000
- Five-year total: approximately 172,000
- Plus: integration add-ons, middleware, admin time
Custom CRM and marketing software:
- Build cost: 60,000 (one-off)
- Annual maintenance: 10,000
- Hosting: 300 per month = 3,600 per year
- Five-year total: 60,000 + 50,000 + 18,000 = 128,000
- No per-seat costs, no tier upgrades, no price increases
Five-year saving: approximately 44,000. The saving grows with more users or higher HubSpot tiers. Use our SaaS ROI calculator for your specific numbers.
How Does the Migration from HubSpot Work?
The migration is phased to minimise disruption:
- Discovery (2 weeks): Map your HubSpot setup: contacts, companies, deals, pipelines, workflows, email templates, landing pages, and integrations. Identify which features are actually used and which are not.
- Design (1 to 2 weeks): Design the custom CRM data model, pipeline stages, workflow automation, and reporting. The design matches your actual process, not HubSpot's template.
- Core CRM build (6 to 8 weeks): Build contacts, deals, pipeline, activity tracking, and basic reporting. This replaces the CRM Hub. Your team can start using it immediately.
- Data migration (2 weeks): Export from HubSpot: contacts, companies, deals, activities, email logs. Map to the new system. Import and validate. Run both systems in parallel.
- Marketing automation build (4 to 6 weeks): Build email sequences, workflow automation, landing pages, and form handling. This replaces the Marketing Hub. Only build the features you actually use.
- Integrations (2 to 3 weeks): Connect the new system to your email platform, website, accounting, and other tools.
- Training and cutover (1 to 2 weeks): Train the team. Switch from HubSpot to the custom system. Keep HubSpot data available for 30 days.
Total timeline: three to seven months, depending on scope.
What HubSpot Features Should You Replicate?
Not every HubSpot feature needs replication. Focus on what your team actually uses:
- CRM: Contacts, companies, deals, pipeline tracking, activity logging. Core functionality that every CRM needs.
- Email tracking: Email opens, clicks, and engagement tracking. Built into custom software natively.
- Marketing automation: Email sequences, workflow triggers, lead nurturing. Only build the workflows you actually use.
- Landing pages: Form handling and landing page creation. Can be built as a simple module in custom software.
- Reporting: Pipeline, marketing, and sales reports. Built to your exact specifications in custom software.
- Integrations: Email sync, website forms, accounting. Built natively, not through HubSpot marketplace.
Features you probably do not need in custom software:
- Social media management (use dedicated tools)
- Ad tracking and management (use the ad platforms directly)
- SEO tools (use dedicated SEO tools)
- Blog hosting (use your CMS)
- Live chat (use a dedicated chat tool or build a simple one)
Building only what you need is one of the main advantages of custom software over a bundled platform. See our guide on bespoke CRM development for more.
When Should You Keep HubSpot vs Build Custom?
HubSpot is the right choice when:
- You have fewer than 30 users
- Your sales and marketing process is fairly standard
- You use the Marketing Hub heavily and it delivers value
- You want everything in one platform without building
Custom software is the right choice when:
- You have 30 or more users
- Your process differs from what HubSpot assumes
- You use less than 40 percent of HubSpot's features
- Your annual HubSpot spend exceeds 25,000
- You need deep integrations that HubSpot makes expensive
The decision framework is the same as for any SaaS replacement. See our guide on build or buy software for the full framework, and how to replace SaaS with custom software for the general migration process.
