Custom CRM development
Custom CRM development so no lead or proposal slips through
Zevnotix Digital builds custom CRM and proposal systems for growing teams in the UK and US whose sales process doesn't fit an off-the-shelf CRM. We design the pipeline around how your team actually sells, turn your best proposal into a template every proposal starts from, and automate the follow-up. Book a free consultation: we'll look at your current process and tell you honestly whether a custom CRM, a configured off-the-shelf one, or a few automations is the right answer.
- Fixed scope and quote before work starts
- Weekly updates and demos
- You own the code, content and accounts
Who this is for
- Teams that have outgrown spreadsheets and lose track of leads.
- Businesses paying for a big CRM that the team works around rather than in.
- Agencies and service firms whose proposals vary by whoever wrote them.
- Owners who can't see the pipeline without asking three people.
What custom CRM development includes
Pipeline built on your stages
Lead and deal views that match the way your team sells, understandable at a glance.
Proposal automation
Templated proposals generated from client data, with e-sign-ready output and consistent pricing.
Automated follow-up
Follow-up sequences and task reminders so no lead goes cold by accident.
One client history
Emails, calls, proposals and notes per client in one place.
Role-based access
Each team member sees what they need; managers see the whole pipeline.
Integrations
Connections to your website forms, email, calendar, accounting and e-signature tools.

How much does a custom CRM cost?
We quote a fixed price after mapping your sales process. A custom CRM is not always the right answer: if a configured HubSpot or Pipedrive plus a few automations would do the job, we'll tell you, because that is cheaper for you.
Where custom does make sense — unusual sales processes, proposal-heavy selling, or per-seat costs that have become painful — the price depends on the number of pipelines, integrations and how much data needs migrating.
What affects the price
- Number of pipelines and user roles
- Proposal templates and pricing logic
- Integrations: email, calendar, accounting, e-sign
- Volume and quality of data to migrate
Custom CRM Development: questions, answered
Why build a custom CRM instead of using HubSpot or Salesforce?
Off-the-shelf CRMs are the right choice for many teams. A custom CRM makes sense when your process doesn't fit their model, when proposals are central to how you sell, or when per-seat pricing has outgrown the value. We'll give you an honest recommendation either way.
Can you migrate our existing contacts and deals?
Yes. We import from spreadsheets or your current CRM and check the data with you before go-live.
Can you automate proposals without replacing our CRM?
Often, yes. Proposal generation and follow-up automation can sit alongside an existing CRM — see our AI and business automation service.
What happens if something goes wrong?
Scope, price and milestones are agreed in writing before any work starts, so there is a fixed reference point if anything drifts. You get weekly progress updates and demos in plain English, which means problems surface in days rather than at the deadline. You own the code, content and accounts we create, so you are never locked in, and ongoing support can be included after launch.
Do you work with clients outside London and the UK?
Yes. We are based in London and work remotely with businesses across the UK, the US and internationally. Calls are scheduled to suit your time zone, and all project communication is written down so nothing depends on being in the same room.
