Replacing Salesforce with custom software eliminates per-seat licensing costs, gives you a CRM that fits your exact sales process, and removes vendor lock-in. For a UK SME with 50 Salesforce users at 80 per seat per month, the annual subscription is 48,000. Custom CRM software costing 60,000 to build, with 10,000 annual maintenance, pays for itself in approximately 18 months and saves 38,000 every year after. The decision is not just about cost: it is about having software that works the way your business works, not the way a vendor assumes a generic business should work.
We help UK SMEs replace Salesforce with custom CRM software, from data migration to user training. See our dedicated Salesforce replacement page for a detailed comparison.
Why Do UK SMEs Replace Salesforce?
The triggers for replacing Salesforce are consistent across the businesses we work with:
- Cost: Salesforce pricing scales linearly with users. At 50 users on the Professional tier (80 per seat), the annual cost is 48,000. Enterprise tier (150 per seat) is 90,000 per year for the same team. Price increases compound this. See our guide on hidden SaaS costs.
- Process mismatch: Salesforce assumes a standard sales process. If your process differs, you either adapt your process to Salesforce or pay for heavy customisation. Heavy customisation on Salesforce can cost as much as building from scratch.
- Complexity: Salesforce is powerful but complex. Many SMEs use 20 percent of its features and pay for 100 percent. The unused features add clutter and confusion for users.
- Integration limits: Connecting Salesforce to your other systems often requires paid AppExchange apps or custom development. Custom software includes integrations natively.
- Vendor lock-in: Your data, workflows, and automations live in Salesforce. Leaving is deliberately difficult. Custom software gives you full ownership.
How Much Can You Save by Replacing Salesforce?
The cost comparison for a 50-user team over five years:
Salesforce Professional (80 per seat):
- Year 1: 48,000
- Year 5 (with 7 percent annual increases): approximately 55,000
- Five-year total: approximately 276,000
- Plus: AppExchange add-ons, integration costs, admin time
Custom CRM 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 price increases, no AppExchange add-ons
Five-year saving: approximately 148,000. The custom CRM is cheaper from year two onward. Use our SaaS ROI calculator for your specific numbers.
How Does the Migration Process Work?
Replacing Salesforce is a phased process designed to minimise disruption:
- Discovery and design (2 to 3 weeks): Map your current Salesforce setup: custom fields, workflows, automations, reports, and integrations. Design the custom CRM data model and user interface. This is the specification for the build.
- Core CRM build (6 to 10 weeks): Build contact management, sales pipeline, and basic reporting. This is the minimum viable CRM that your team can start using while advanced features are built.
- Data migration (2 to 3 weeks): Export data from Salesforce (contacts, accounts, opportunities, activities, custom fields). Map fields to the new CRM. Import, validate, and reconcile. Run old and new systems in parallel.
- Advanced features (4 to 6 weeks): Build custom workflows, automations, advanced reporting, and integrations that were in Salesforce. The goal is feature parity or better for the features you actually use.
- Integration (2 to 4 weeks): Connect the new CRM to your email, accounting, marketing, and other systems. Native integrations replace AppExchange add-ons.
- User training and cutover (1 to 2 weeks): Train the team on the new CRM. Switch from Salesforce to the custom system. Keep Salesforce data available as backup for 30 days.
Total timeline: four to eight months. The core system is usable within the first three months.
What About Salesforce Customisation?
Some UK SMEs have heavily customised Salesforce to fit their process. The question is whether to keep customising Salesforce or build custom software. The decision point:
- Light customisation (custom fields, basic workflow rules, standard reports): Keep Salesforce. The customisation cost is low and the subscription is manageable for small teams.
- Heavy customisation (custom objects, complex workflows, Apex code, extensive integrations): The customisation cost on Salesforce can approach or exceed the cost of building bespoke. At that point, you are paying Salesforce subscription prices for what is essentially custom software, without owning it.
If your Salesforce customisation costs exceed 20,000 to 30,000, building custom software is likely cheaper over three to five years, and you own the result. See our guide on bespoke CRM development for what custom involves.
What Features Do You Need to Replicate?
When replacing Salesforce, identify which features your team actually uses. Most SMEs use a fraction of Salesforce's capability. The typical features that need replication:
- Contact and account management: Contact details, company relationships, communication history.
- Sales pipeline: Opportunity tracking, pipeline stages, probability, forecast.
- Activity tracking: Calls, emails, meetings, tasks linked to contacts and opportunities.
- Custom fields: The specific data fields your business needs, which in custom software are part of the design, not a customisation.
- Workflow automation: Automated task creation, email alerts, status transitions.
- Reporting: Pipeline reports, activity reports, custom dashboards. In custom software, these are built to your exact specifications.
- Integrations: Email sync, accounting sync, marketing automation. Built natively in custom software.
Features you probably do not need: the extensive AppExchange ecosystem, Einstein AI (unless you use it), Salesforce Communities, and the administrative complexity that comes with a platform designed for enterprise.
What Are the Risks of Replacing Salesforce?
The main risks and their mitigations:
- Data loss during migration: Mitigated by full backup before migration, data validation after import, and parallel running for 30 days.
- Feature gaps: The new CRM may lack a feature someone relied on. Mitigated by thorough discovery of what features are actually used.
- User adoption: Staff used to Salesforce need training and support. Mitigated by a clean, simpler interface (custom CRM has only the features you need) and phased rollout.
- Integration gaps: Replacing AppExchange integrations with custom integrations takes time. Mitigated by prioritising the most critical integrations first.
