HOW WE BUILD
How a bespoke CRM project works
No six-month requirements document. We start from how your business already works, automate the busywork first, and put a working CRM in front of your team early.
- 01
Map
A short workshop on how you actually win and deliver work: enquiry sources, stages, approvals, documents and who does what.
- 02
Automate
We decide what AI agents and workflows take off your team's plate first: replies, chasers, call notes, renewals and reports.
- 03
Build
Your CRM is built in fortnightly releases you can click through, connected to your website, inbox, phones and accounts package.
- 04
Run
Data migrated and checked, the team trained, and support in UK hours. You own the code, the data and the documentation.
WHY CUSTOM
Why UK businesses choose a custom CRM
Stop paying for seats you don't need
Per-user CRM pricing climbs with every hire, and automation sits in the top tier. A bespoke CRM is built once and owned, so growing the team doesn't grow the bill.
Your process, not a template
Off-the-shelf CRMs make you rename fields and work around screens. A custom build has the records, stages and approvals your business really uses.
One place for every enquiry
Website forms, phone calls, email, LinkedIn and referral partners all land in one pipeline, assigned to the right person in seconds.
Follow-up that never slips
AI agents draft replies and chase quotes that go quiet, and reminders make sure every callback, renewal and review happens on time.
Finance without retyping
Quotes become invoices in Xero, QuickBooks or Sage with VAT applied, and payment status flows back to the deal.
Data you control
Hosted in a UK region or on your own servers, with role-based access and a full export whenever you want it.
CUSTOM VS OFF-THE-SHELF
Renting a CRM or owning one?
Off-the-shelf CRMs are quick to start and expensive to grow into. Here's how the two compare once a team is relying on it every day.
| Off-the-shelf | Custom CRM | |
|---|---|---|
| Pricing | Per user, per month, rising with tiers | Fixed build, then optional support |
| Fit | Your team adapts to the software | The software follows your process |
| Automation | Locked to higher plans | Built in where it saves time |
| Integrations | Marketplace apps, extra fees | Built for your stack |
| Ownership | Rented; leave and rebuild | You own the code and data |
| Reporting | Generic dashboards | The numbers your board asks for |
BUILT FOR THE UK
Connected to the tools UK teams already use
A CRM only saves time when it talks to everything else. We build the integrations in, rather than bolting on marketplace apps with their own monthly fees.
Xero, QuickBooks & Sage
Contacts, quotes, invoices and payments kept in step with your accounts package, ready for Making Tax Digital and the move to e-invoicing.
Microsoft 365 & Google Workspace
Outlook or Gmail conversations and calendar meetings logged on the right record, with Teams or Slack alerts for hot leads.
Phones & VoIP
Click-to-call, call logging and recordings from RingCentral, Aircall, 3CX or your existing phone system.
Companies House lookups
Pull registered company details, officers and addresses straight into a new account instead of copying them by hand.
Payments & Direct Debit
Stripe or GoCardless links on quotes and invoices, with payment status updating the deal automatically.
AI agents that do the work
Agents that qualify enquiries, summarise calls and email threads, suggest the next step and keep records clean, with your team in charge.
BY INDUSTRY
Bespoke CRM software for UK sectors
Every industry has its own records and rules. Your CRM should hold the ones your business actually uses.
Estate & letting agents
Applicants, valuations, viewings, offers, tenancies and renewals, with portal enquiries pulled into one pipeline and compliance dates tracked.
Recruitment agencies
Candidates, clients, vacancies, interviews, placements and rebates, with consent and retention dates handled for UK GDPR.
Law firms & professional services
Enquiries, conflict checks, matters, deadlines and fee quotes, using our Legal & Law edition or a fully custom build.
Trades & field services
Quotes, site surveys, jobs, engineers, certificates and service reminders, with the office and the van working from the same record.
B2B, manufacturing & wholesale
Accounts, price lists, quotes, orders, distributors and account managers, with renewals and reorders chased automatically.
Training, education & membership
Enquiries, courses, enrolments, renewals and instalments, with automated reminders by email and text.
HUBSPOT, SALESFORCE OR BESPOKE?
Custom CRM, SalesKnot or a global platform?

HubSpot, Salesforce, Zoho or Dynamics 365

- Monthly per-user fees, with automation in higher tiers
- We set up, customise, integrate and migrate
SalesKnot, ready to go
- Our own CRM with workflows and AI agents built in
- Editions for legal, real estate, call centres and more

PRICING
What a custom CRM costs in the UK
We price bespoke CRMs as a fixed quote after a short scoping call, so the number you approve is the number you pay. After launch, support is optional and there are no licence fees per user.
What decides the cost
- Number of modules (leads, sales, jobs, bookings, billing, support)
- Integrations: accounts package, Microsoft 365, phones, payments, website
- Number of roles, teams and approval steps
- Migrating data from spreadsheets or an old CRM
- Customer portal, AI agents, hosting and ongoing support
Need to start this month? SalesKnot is $25 per user per month, or $35 with an industry edition, with setup quoted once. We'll tell you honestly when a custom build makes more sense.
BUYER'S CHECKLIST
How to choose a CRM developer in the UK
Before you sign with any CRM supplier, ask these six questions. They matter more than the feature list.
- Will it fit how your team works today, or will they keep a spreadsheet on the side?
- What will it cost per user in three years, including the automation tier?
- Does it connect to your accounts package, inbox and phone system?
- Where is the data hosted, and can you export all of it at any time?
- Who owns the configuration and code if you change supplier?
- Is support available in UK hours from someone who knows your setup?

FAQ
Custom CRM development in the UK: common questions
How much does custom CRM development cost in the UK?
It depends on the modules, integrations and data migration. A focused CRM for one team is a much smaller build than a multi-department system with a customer portal. We give a fixed quote after a short scoping call, with no per-user licence fees afterwards. If you want something ready-made, SalesKnot starts at $25 per user per month.
Is a bespoke CRM better than HubSpot or Salesforce?
Not always. If your process matches their standard setup, a platform can be the quickest route, and we set those up too. A bespoke CRM wins when your workflow is specific, per-seat costs are climbing, you need deep integrations, or you want to own your system outright. We compare both honestly on the first call.
Is the CRM UK GDPR compliant?
We build to UK GDPR from the start: lawful basis and consent recorded on each contact, retention rules, subject access and erasure requests handled in a few clicks, role-based access and audit trails. Hosting can be in a UK region so personal data stays in the country.
Can it integrate with Xero, QuickBooks or Sage?
Yes. Contacts, quotes, invoices and payments sync with your accounts package, so nobody retypes figures and VAT is applied consistently.
Will the CRM be ready for UK e-invoicing?
The government has announced that VAT invoices are moving to mandatory e-invoicing later this decade. Your CRM doesn't need to issue e-invoices itself; we connect it to your accounts package and its e-invoicing provider so quotes, orders and invoices flow without retyping.
How long does a custom CRM take to build?
A first working version for one team usually goes live in weeks, not months, and we add modules in fortnightly releases after that. You see and test progress throughout rather than waiting for a big reveal.
Do you work with businesses across the UK?
Yes. We work remotely with companies in London, Manchester, Birmingham, Leeds, Glasgow, Edinburgh, Bristol and across the UK, with calls in UK business hours.
Can you migrate us from our current CRM or spreadsheets?
Yes. We map, clean and de-duplicate data from Excel, Google Sheets, HubSpot, Salesforce, Zoho, Pipedrive, Dynamics or a legacy system, and check it with you before go-live.
Do you also work with Microsoft Dynamics 365?
Yes. Dynamics is where our CRM work started, including projects for Vodafone UK. We still audit, fix and support Dynamics 365, and we'll tell you honestly when a lighter custom CRM would serve you better.
