Second place in our ranking of practice management tools for UK therapists, on 13 out of 16. It's a British company billing in sterling with booking and reminders in the price — but the advertised figure isn't the one you pay, and video isn't included. Here's the whole picture.
A £27.95 subscription means one thing if you take home £22,000 and quite another if you take home £45,000. Work out your real figure after tax, National Insurance and running costs before you judge whether any of this is worth it.

We have no commercial relationship with WriteUpp and earn nothing if you sign up. There are no affiliate links to WriteUpp anywhere on this site. This review is desk research scored against a published rule, marked from WriteUpp's own pricing, security and export documentation as it stood in August 2026 — not a month of hands-on use, and we would rather say so than imply otherwise. The site is published by the team behind Practik, a free take-home pay calculator, which is not practice management software and doesn't compete with anything reviewed here.
WriteUpp is a British practice management system that has been around long enough to be unglamorous. Diary, client records, notes, invoicing, online booking, SMS reminders — the working parts of a small practice, from a company that bills in pounds and answers the phone in this country. It came second in our ranking, one point behind bacpac, and it is the tool we'd recommend to the largest number of readers.
It's also the tool whose pricing is most often quoted wrongly, including by articles that are ostensibly reviewing it. So this review leads with money.
WriteUpp advertises two plans a solo therapist would consider, and both prices on its site exclude VAT. That matters more here than it does for most software purchases, because the majority of solo therapists are below the VAT registration threshold and therefore cannot reclaim it. If you're not VAT-registered, the price with VAT is simply the price.
| Plan | Advertised | What you pay | Per year |
|---|---|---|---|
| Flex | £19.95/mo | £23.94/mo | £287 |
| Flex + online booking | £24.90/mo | £29.88/mo | £359 |
| Solo | £27.95/mo | £33.54/mo | £402 |
The interesting line is the middle one. Flex looks like the budget option at £19.95, but online booking is a £4.95 monthly add-on on that plan — and online booking is the feature most therapists actually want, because it is the one that stops the back-and-forth emails. Add it and Flex costs £29.88 against Solo's £33.54. The real gap between the "cheap" plan and the proper one is £3.66 a month, or £44 a year, and Solo also includes 100 SMS credits a month and a second non-clinical user. Unless you genuinely won't use booking, Flex is a false economy.
Three things sit outside both plans and are worth knowing about before you commit:
Eight criteria, each worth 2, 1 or 0 against the rule published on the ranking page. WriteUpp took full marks on five and dropped a point on three.
None of those three is a reason not to buy it. Together they're the difference between a tool that's right for most people and one that's right for everyone, which is roughly where WriteUpp sits.
Buy WriteUpp if you're a solo UK therapist seeing clients mainly face to face, you want online booking and SMS reminders included rather than metered, and you'd rather deal with a British company on sterling invoices when something goes wrong. It is the safest ordinary choice in the category, and the 30-day trial means you can find out for free.
Buy something else if one of these is you:
Practice management software is an allowable business expense, so the sticker price isn't the real price. For a sole trader paying basic-rate tax, every £1 of allowable cost saves about 26p — 20% income tax plus 6% Class 4 National Insurance. WriteUpp Solo at £402 a year is therefore about £298 after tax relief: roughly five sessions a year at a £60 fee, or about two and a half at £120.
Five sessions a year to never write an invoice by hand again is an easy yes for most people. The trap is never one subscription — it's four. We've worked out what every tool in the ranking costs in sessions after tax, including what happens when you stack them.
The Solo plan is advertised from £27.95 a month and the Flex plan from £19.95, both excluding VAT. With VAT at 20% that's £33.54 and £23.94 respectively. Online booking is included on Solo but costs £4.95 a month extra on Flex, which narrows the gap between them to £3.66 a month.
No — video consultation is a paid add-on on every plan, though the 30-day free trial includes 1,000 video minutes. If most of your work is online, compare it against Jane and Cliniko, both of which include telehealth in the subscription rather than charging for it separately.
WriteUpp is a UK company that states UK data hosting, ISO 27001 certification and a product built around GDPR, which is why it takes full marks on our data criterion. As the data controller for your client records, you should still ask for the current data processing agreement and confirm the position yourself before you migrate — that responsibility is yours, not the vendor's.
Yes. WriteUpp documents a self-service export covering clients, notes and invoices, which you can run without asking support. That is worth more than it sounds: it's the single question we'd put to any vendor before migrating, and not every tool in this category answers it as cleanly.
Thirty days, with no credit card required. That's at the generous end of the category — bacpac and Cliniko also offer 30 days, Zanda offers 14, and Jane offers none at all. Use it with real appointments rather than test data, because the things that will annoy you about any of these tools only show up in ordinary use.
bacpac if you're a counsellor or psychotherapist working face to face and want the cheapest credible UK system built for this profession — it's £18 a month including VAT, with outcome measures built in. WriteUpp if you want online booking, SMS reminders and payment collection in one place, or your practice is broader than talking therapy. bacpac scored 14 to WriteUpp's 13, and the gap is genuinely that narrow.
