CRM for UK sole traders: which is the simplest?

What to take away

Start with the tax record, not the pipeline. A CRM that cannot export clean client lines adds work at self assessment.
The £90,000 VAT registration threshold (GOV.UK, from 1 April 2024) is the first filter: below it, VAT fields are clutter.
Capsule is the simplest all-round pick for many UK sole traders: free for up to two users, with contacts, tasks and a short pipeline.
Less Annoying CRM is a close secondone flat paid plan per user, no tiers, built for very small firms.
Test the export before you pay. A plain CSV that matches your bookkeeping categories beats a longer feature list.

Why most CRM shortlists miss sole traders

Search results for customer relationship management tools often assume a sales team. HubSpot, Zoho CRM and Pipedrive are built around pipelines, owners and dashboards. A sole trader is sales, admin and invoice clerk at once.

The useful question is narrower. Which single-user plan closes the loop from enquiry to paid invoice with the fewest manual steps?

Most vendor pages rank tools by forecasting, territory rules and team dashboards. A one-person business will pay for those and open none.

The UK tax tests a simple CRM has to pass

Trading as a sole trader means you and the business are the same legal person for tax purposes. You register with HMRC, keep records and file a self assessment. The GOV.UK guidance on how to become a sole trader covers the registration step.

VAT registration test

Taxable turnover over £90,000 in 12 months?

Yes

Skip VAT fields as clutter

VAT is the first real filter. Registration is required once taxable turnover passes £90,000 in any rolling 12 month period (GOV.UK, from 1 April 2024). Below that line VAT fields are clutter; above it, an invoice without a rate creates a correction you make twice. The VAT registration guidance sets out the tests.

Making Tax Digital for VAT requires digital records and software that can pass them on. If the CRM raises the invoice, it has to hand data to the filing tool cleanly. GOV.UK's Making Tax Digital guidance covers the record-keeping rule.

If invoicing is where the time goes, invoice automation for small businesses covers the handover from quote to ledger.

Which is simplest? For most UK sole traders, Capsule. It is UK-based, free for up to two users, and keeps contacts, tasks and a short pipeline on one screen. Less Annoying CRM is simpler by design, but one flat paid plan and US support may suit fewer UK tax workflows.

A shortlist you can run in a week

Name the three fields you would open every day, such as client, last contact and next action. If Capsule or HubSpot cannot show them on one screen, move on.
Import ten real clients, including one abroad and one with two contacts. Check the addresses and dates survive in Zoho CRM and Pipedrive.
Export the same ten as CSV and open the file in your bookkeeping tool. Columns that need manual fixing mean the integration claim is marketing.

Run one billing cycle before an annual commitment. A month shows whether follow-up reminders happen and whether the export still matches.

If you bill by the hour, time tracking software for freelancers sets out what to check when the timer and the client record must agree.

Where a lightweight CRM stops being enough

Add a subcontractor or a second trading name and the single-user plan starts to strain. Capsule's free plan covers two users. Zoho's free tier stops at three users. HubSpot's free tier can hide upgrade prompts.

Data protection shifts too. Once you hold client data for marketing as well as delivery, you need a lawful basis and a retention rule, not just a tidy list.

Watch the change points rather than the feature list. Two people needing the same record, a client asking for a data export, or an accountant wanting a monthly file all mean you have outgrown the lightest tier.

Common questions

Is a spreadsheet enough as a CRM for a sole trader?

For a handful of repeat clients, yes. Google Sheets or Microsoft Excel with a follow-up column covers the basics. Move on when you lose track of who was last contacted.

Do I need VAT fields if I am not VAT registered?

No. Below the £90,000 threshold, VAT fields add noise. Pick a tool such as Capsule or Zoho that can switch them on later rather than paying for them now.

Can one tool handle both CRM and accounting?

Rarely well. FreeAgent and Xero hold contacts and invoices, but they are not pipeline CRMs. Capsule and Pipedrive export to accounting tools; check the CSV first.

How should a sole trader handle client data?

Treat it as a record of personal data. Keep only what the work needs, set a deletion date for enquiries that go nowhere, and check who can access a shared account.
