TrustSolo is a UK tool for freelancers in their first years. It covers the admin around freelancing — writing contracts, getting them signed, invoicing, chasing late payers and keeping track of tax — in one place.
Most freelancers in the UK start the same way: a first paying client, a quick invoice in Word, a contract copied from a forum post, and a growing stack of questions about tax and payment terms. TrustSolo closes that gap.
Key Features
UK contracts with online signature — ten templates written around UK law, a general agreement plus nine disciplines from copywriting and design to photography, bookkeeping and tutoring. Fill in the gaps, send for e-signature, and the signed PDF is stored against the client.
Invoices with a payment link — raise one in a couple of clicks with a Stripe payment link, or bank transfer if you prefer. VAT applied automatically if you're VAT-registered.
Automatic chasing of late payers — reminders go to your client on a schedule you control, so you're not the one sending that email.
Income and tax estimates — your income updates as you invoice, with an estimate of Income Tax and Class 4 NI on your profit and a plain-English payments-on-account timeline.
Four free calculators, no signup — a tax estimator, a freelance rate calculator, a day-rate-to-salary converter and a statutory late-payment interest calculator, every figure cited from gov.uk.
Honest about what it isn't
TrustSolo isn't an accountant and doesn't replace one: the tax figure is an estimate, not a tax return, and it files nothing with HMRC. Contract templates are informational, not a substitute for legal advice. It's UK-only by design — contracts, tax bands and late-payment rules don't travel.
Built for the first years, not for agencies. £14 a month after a 30-day free trial, no credit card.
