What is the simplest system for a sole trader?

One job-led app for quotes and invoices, photo receipts, and a spreadsheet or accountant for tax. Complexity is a tax on your attention — add only what you use.

When do I need to register for VAT?

When your taxable turnover in any rolling 12-month period exceeds the VAT threshold (currently 90,000 GBP). Monitor it actively — crossing the threshold unexpectedly creates a backdated liability.

How do I price my own time as a sole trader?

Start with your desired annual take-home, add tax and National Insurance, add overhead costs (van, tools, insurance, software, training), divide by realistic billable days (typically 200 to 220 per year). That gives your daily rate floor.

Self-employed tradesman guide — less admin, more jobs moving

Being self-employed is two jobs: doing the trade and running the business. This guide is the practical spine — quoting, scheduling, invoicing and records — without drowning in software built for office managers. Pro Quoter is a low-admin hub: enquiry → measure → AI-assisted quote → send → book → invoice → records, mobile-first for real sites.

The weekly rhythm

Monday planning, midweek on-site execution, Friday invoicing and chasing. If quotes only happen “when you get a minute”, you lose work to faster competitors.

Money: keep it boring

Boring money habits beat heroic year-end panic. Capture expenses weekly, invoice on completion, and know your rough profit before you spend.

Ditch the notebook where it hurts

Measurements, extras and customer wording should live with the job — not on the back of a board. Built for bad signal: save on-site, sync when you are back online.

Setting up: the minimum you need to start properly

Register as self-employed with HMRC within three months of starting. Open a separate business bank account — even a free basic account keeps business and personal spending clear. Set up a basic record system: invoices out, expenses in, CIS deductions if applicable.

You do not need an accountant on day one, but you do need a system you will stick to. The trades who struggle at year end ran the first eighteen months purely from memory and a bank statement.

HMRC registration — do it immediately, not at year end
Separate business account — discipline beats clever solutions
Simple invoicing from day one — consistent is essential
Accountant from year two — the cost pays for itself in avoided mistakes

The billing cycle that keeps cash flowing

Invoice on the day of completion or the next morning. Payment terms of 7 or 14 days are common in domestic trade work. Send a reminder on day 10 if unpaid. Follow up by phone on day 14.

Trades who send professional PDFs immediately and follow up systematically get paid faster than those who send invoices late and chase vaguely.
