About TrustSolo

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, payment terms, and what "proper" looks like. TrustSolo closes that gap: contracts, invoicing, getting paid and knowing what you owe, in one place, built in the UK for UK freelancers. Contracts: 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 it for online signature, and the signed PDF is stored against the client. Invoicing and payment: raise an invoice in a couple of clicks with a Stripe payment link, or bank transfer details if you prefer. VAT is applied automatically if you are VAT-registered. When a client goes past due, TrustSolo chases them on a schedule you control, so you are not the one sending that email. Income and tax: your income updates as you invoice, alongside an estimate of Income Tax and Class 4 NI on your profit and a plain-English payments-on-account timeline, so January is not a surprise. The goal is simple: a new freelancer with their first client should be able to send a professionally structured agreement, or issue an invoice with an online payment link, in under ten minutes, without reading any documentation. We are honest about what we are not. TrustSolo is not an accountant and does not 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 is UK-only by design: contracts, tax bands and late-payment rules do not travel. There are also four free calculators that need no account: 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. TrustSolo is £14 a month after a 30-day free trial.

TrustSolo FAQ

What does TrustSolo include?

TrustSolo provides freelancers with simple business management software to help with contracts, invoicing, payments, income tracking and tax estimates — all the essential tools for your first years, in one place.

What does it cost?

It's £14 a month, or £140 a year — that's everything TrustSolo does, with no per-invoice fees.

Is there a free trial?

Yes — every account starts with a 30-day free trial, no charge up front.

Does TrustSolo file my tax return?

No. TrustSolo gives you a plain-English estimate of what to set aside for Income Tax and Class 4 National Insurance — it doesn't submit anything to HMRC. You (or your accountant) still file your Self Assessment.

Can I customise the contracts?

Yes. Start from a template built for your discipline and configure the clauses that fit — IP ownership, termination, delivery and more. The templates reference UK law and are a starting point you control, not a substitute for a solicitor's review.
