When off-the-shelf is better
If your workflow is lead capture, pipeline stages, email tracking, tasks, and reporting, buy a CRM. The subscription will be cheaper than building and maintaining your own. Off-the-shelf is also better when you need fast deployment, a large plugin ecosystem, or sales team familiarity.
Customisation inside an existing CRM should be tried before bespoke development. Many problems are configuration problems, not software problems.
When custom CRM makes sense
A custom CRM is justified when the CRM is really an operations platform: complex quoting, booking, compliance checks, fulfilment workflow, customer portals, field teams, inventory, custom approval chains, or deep sector-specific data. It also makes sense when per-seat pricing becomes expensive at scale and the feature set you use is narrow but highly specific.
The strongest case is when CRM data must connect directly to proprietary business logic. If a salesperson action triggers delivery operations, document generation, billing, and customer communication, a custom system may reduce tool switching and errors.
What a custom CRM includes
A serious custom CRM normally includes contact and company records, pipeline or workflow stages, activity history, tasks, notes, file attachments, email templates, role permissions, reporting, import/export, notifications, and integrations with email, calendar, accounting, payment, or support systems.
The hidden cost is data migration. Old CRM data is often duplicated, inconsistent, and missing key fields. Budget time to clean and map it. Bad data moved into a new CRM is still bad data.
Cost and build phases
A focused custom CRM starts around £20,000-£45,000. A CRM with customer portal, workflow automation, reporting, and integrations usually costs £45,000-£120,000. Enterprise-grade systems with complex permissions, audit logs, and multiple departments can exceed £150,000.
Phase one should cover the critical workflow only. Add advanced reporting, automation, and integrations after users have proved the system fits their daily work.
AyTech note: The safest projects start with a narrow, measurable workflow, then expand after real users prove the value. This keeps budgets controlled and gives Google, buyers, and stakeholders clearer proof of expertise.
