How it works

The sequence matters more than the label. Skipping the first one is how projects in this area go wrong.

  1. We trace how a customer moves from enquiry to sale to renewal, and who does what.

From the people who use it daily

Operations directors, CTOs and plant managers — the ones still using the system a year after the invoice cleared.

What is a custom CRM?

A custom CRM (customer relationship management) system is software built for one business to manage contacts, leads, sales, quotes and customer service around its own process. Unlike off-the-shelf CRM, it includes only what the business needs and connects directly to its other systems.

Is a custom CRM better than Salesforce or HubSpot?

For businesses with standard sales processes, off-the-shelf CRMs work well. A custom CRM is better when your process is specialised, when you're paying for many seats and add-ons, or when the CRM needs to connect deeply with operations.

How much does a custom CRM cost?

Cost depends on features, integrations and users. Because there are no per-seat fees, a custom CRM often costs less over three years than a mid-tier subscription for a growing team.

How long does it take to build a custom CRM?

A focused custom CRM typically takes 8 to 12 weeks to first release, including migrating your existing data.

Can you migrate our data from our current CRM?

Yes. We export contacts, companies, deals, notes and activity history from your current CRM and map them into the new system, then reconcile the results with you.

Can a custom CRM include AI features?

Yes. Custom CRMs can include AI that drafts emails, summarises calls and meetings, scores leads or suggests next steps, using your own customer data.
