How to Do a Tax Return when Self Employed: Step-by-Step Guide
Discover the process of paying tax as a self-employed individual or freelancer in the UK. Our guide explains all of the necessary steps in detail.
You're great with numbers, but how do you get the word out there about your skills? We’ve put this guide together to make the pipeline add up.
Read on to find out how to get clients as a freelance bookkeeper in the UK - from defining your ideal customer to building a repeatable outreach-and-follow-up rhythm that actually wins business.
Along the way, you'll see exactly where to find clients, how to pitch your services without cringing, and how to stay compliant.
And if you invoice overseas or work with clients who pay in different currencies, we’ve explained how Wise Business can help, thanks to its ability to connect to Xero and QuickBooks to automatically sync your multi-currency transactions, making reconciliation a breeze.
Before you worry about where to find clients, get clear on who you want.
An Ideal Customer Profile (ICP) keeps your messaging, pricing and prospecting focused.
Think of it as a one-page snapshot of the client types you serve best and profitably.
Write two or three ICPs you genuinely want and build everything that follows around them:
Industry & model: e.g., e-commerce brands on Shopify, trades under CIS, creatives on project retainers, consultants working B2B, micro-SaaS using Stripe. If you'll work with builders or subcontractors, remember CIS rules change how payments and deductions work1, and being fluent here is a real differentiator.
Size & stage: revenue range, VAT status, headcount, whether they're on cash vs accrual, and who actually signs your proposal.
Compliance context: MTD for VAT, payroll, CIS, or specific industry schemes. Making Tax Digital2 continues to expand, and being the bookkeeper who keeps clients compliant (and calm) is a superpower.
Software stack: Shortlist your "supported stack" so you attract the right fit (Xero, QuickBooks, FreeAgent, Dext, Stripe, WooCommerce).
Cadence & scope: weekly vs. monthly bookkeeping, VAT returns, payroll, credit control, management reports, cleanup projects, and quarterly reviews.
Buying triggers: received a VAT notice, switching accountants, expanding internationally, moving to Xero, or hiring their first employee.
When it comes to targeting the right client, your pitch should read like a diagnosis and a plan, not a generic brochure.
Anchor it in the pains your ICP feels and the outcomes they care about:
Lead with the outcome. "We help UK Shopify stores keep stock, cash and VAT spot-on, so you can scale without surprise tax bills."
Name the specific problems. Payment gateways not reconciling, VAT mis-codings, messy suspense accounts, CIS deductions, or directors' loans out of control. If you support MTD workflows2 end-to-end, say so.
Show proof. Mini case studies, before/after screenshots (anonymised), and any recognised credentials. QuickBooks or Xero certification3 is worth mentioning, and both programmes come with training, credibility and directory exposure.
Make it easy to say yes. Offer a short diagnostic ("chart of accounts + bank feed review") and a fixed-fee onboarding plan with a 30-day check-in.
A quick note on compliance signals in your pitch: If you're supervised for Anti-Money Laundering (AML)4 by a professional body (AAT/ICB/ACCA/ICAEW) or by HMRC, then say it plainly. Also, add your ICO data-protection fee status5. These small cues build trust fast.
Focus your energy where your ICP is already looking. Complete and polish your listings on Xero's Advisor Directory and QuickBooks' Find-a-ProAdvisor so prospects can filter by software, services and industry, and so your certification actually works as a lead magnet.
Add credibility with professional-body directories that UK small businesses trust. AAT's "Find an Accountant or Bookkeeper" and the ICB member directory6 both emphasise licensed, insured practitioners.
Claim and optimise your Google Business Profile so you appear in local searches ("bookkeeper near me"). Keep hours, services and reviews current, as Google surfaces this data prominently.
On LinkedIn, use a benefit-led headline and an "About" section that reads like a short promise to your ICP. LinkedIn's own guidance recommends making the headline more than a job title and using your summary to show the value you bring7.
If you prefer in-person referrals, groups like BNI can work when you commit weekly. The model is "one seat per profession" in each chapter, which helps you avoid competing with another bookkeeper in the room.
A repeatable outreach plan keeps your pipeline full between referrals and directory leads. For B2B corporate emails, it's important to build your list the right way (and legally).
The UK's PECR rules don't require prior consent, but you must identify yourself and provide a working opt-out in every message8.
Keep a do-not-contact list and respect it (GDPR still applies to the personal data you process).
Here's an example of how your weekly cadence could look:
Most wins happen after the first message. Sales email data shows reply rates jump when you follow up quickly (ideally within 24 hours after the initial reach-out9), and a sequence of polite, value-adding nudges outperforms one-and-done.
Your simple follow-up rhythm:
Keep every message short, clear, opt-out friendly, and put the burden on you ("I'll send the outline if helpful"). If you contact corporates, remember the PECR B2B rules8,10 and always include an unsubscribe method.
If you invoice clients in different countries, or just want fewer headaches reconciling payments, Wise Business gives you local account details in multiple currencies (like GBP, EUR and USD) so clients can pay you "like a local.
This lets you hold over 40+ currencies and convert as needed. Connect Wise to Xero (and other accounting tools) to import bills, pay them from Wise, and have those bills automatically marked as paid in Xero, which is useful if you manage payables for clients or want a cleaner month-end.
Getting paid is simpler, too: create payment links or full invoices inside Wise so customers can settle quickly, and funds land straight in your Wise account.
For spending, issue a Wise multi-currency debit card and instant virtual cards to separate expenses or empower team members, then reconcile the feedback in your books.
Connect your Wise Business account to your bookkeeping workflow and make international transactions easier for all parties involved.
Be Smart, Get Wise.
"I did the maths and realised that for a £20,000 payment, I saved around £700 compared to my traditional bank. Over time, that adds up to thousands of pounds, which I can invest back into the business.”
If you provide accountancy services to the public (including bookkeeping), you must be supervised for AML, either by your professional body (AAT, ICB, ACCA, ICAEW, etc.) or by HMRC directly4, if you're not already covered.
Make sure to state your supervisor clearly in your engagement letter.
Most small UK businesses that process personal data (which bookkeeping almost always does) must pay the ICO fee unless exempt5.
The ICO's checker confirms obligations and lets you register.
All VAT-registered businesses must keep digital records and file via MTD-compatible software2.
HMRC continues to expand the programme and support resources for agents. Positioning yourself as the "MTD-ready" bookkeeper is a competitive edge.
Start with Xero Advisor Directory, QuickBooks Find-a-ProAdvisor, AAT's "Find an Accountant or Bookkeeper" and ICB's directory. Keep these profiles consistent with your website and Google Business Profile.
Yes, you can email corporate subscribers without prior consent under PECR, but you must not conceal your identity and must include a working opt-out in every message8.
Keep a suppression list and respect it. (GDPR still governs how you handle personal data.)
There's no magic number when it comes to following up after the initial reach out.
That said, data suggests your first follow-up within 24 hours sees a noticeable bump in replies9, and a short sequence of polite, value-adding follow-ups generally outperforms a single email.
Test what works for your niche and keep your messages helpful.
Absolutely. Contractors and subcontractors under the Construction Industry Scheme (CIS) need accurate deductions and filings1.
Positioning yourself as CIS-savvy helps you stand out. Link to HMRC guidance on your website and include CIS setup/reviews in your scope.
