WriteUpp is an established platform that many multi-discipline clinics know well; Sessionly is a newer platform built exclusively for UK talk therapy.

Who each platform is for
WriteUpp
Established UK practice management for multi-discipline clinics — physiotherapy, podiatry, osteopathy, counselling. Serves the allied-health end of the market well, with mature integrations (Xero, Stripe, MailChimp, Twilio, Zapier and Healthcode) and a substantial user base built up over a decade.
Sessionly
UK practice management software for therapists, counsellors and counselling agencies / CICs. Named UK outcome measures, BACP-aligned defaults, dual-code clinical governance, waiting-list workflows, supervision and CPD tracking, and flat-rate pricing that does not penalise team growth. Newer and more narrowly focused on UK therapy work than multi-discipline clinical platforms.

Multi-discipline breadth vs UK therapy focus
WriteUpp's breadth is a genuine strength. If your clinic mixes counselling with physiotherapy or osteopathy, running one platform across every practitioner is a real advantage. WriteUpp's terminology, note templates and defaults sit at a general-clinical level so nothing feels alien to a physio or a podiatrist.
That breadth is also the trade-off for UK therapy practices. Sessionly ships PHQ-9, GAD-7, CORE-10, CORE-OM, YP-CORE, DES-II, WSAS and Goal-Based Outcomes as named, scored features with clinical risk flags — rather than generic form-builder configuration — because UK counselling governance frameworks expect them by name. Notes are structured for counselling and psychotherapy; supervision session tracking and CPD logging sit alongside client work in the same platform. If everyone in your practice is a UK counsellor or psychotherapist, that focus pays off in every screen.
Pricing model: per user vs flat
WriteUpp uses per-user pricing across its tiers. That is fine at 1–3 practitioners but scales quickly: a 10-therapist agency typically lands around £200–£280/month and a 25-therapist agency £500–£700+/month at WriteUpp's published rates.
Sessionly's Agency plan is flat at £49.99/month for up to 25 therapists. If your team grows, the software bill does not. For a like-for-like walkthrough at each team size, see our WriteUpp alternative page, which breaks out pricing at 2, 5, 10, 15 and 25 therapists side by side.
Practice-management depth and agency mode
WriteUpp handles multi-user setups but is not built specifically for the shape of a UK counselling agency. Sessionly's practice-management depth is available across solo and agency use, not held behind an agency tier: two-code clinical governance (clinical record code for admin, anonymous code for clinical work), waiting-list workflows, note governance with version history and delete-approvals, supervision session tracking, CPD logging, and funding-and-demographic reporting for grant-funded services.
On top of that, agency mode adds features specifically for teams: therapist-to-client assignment and management, shared calendars with room booking, agency funding tracking (including external funding sources), therapist billing management for internal costs, and secure communications. None of this changes the underlying calendar and notes; it adds the layer UK counselling agencies and CICs actually need for clinical governance and funder reporting.
Which should you choose?
Choose WriteUpp if…
- • Your practice is multi-discipline (counselling alongside physiotherapy, osteopathy or podiatry).
- • Insurance billing via Healthcode (BUPA, AXA, Aviva, Vitality) is a large part of your income.
- • You already have an established Xero / Zapier / Twilio stack you want to keep.
- • You value a decade-plus of product maturity and a large existing user base.
Choose Sessionly if…
- • You're a UK counsellor, psychotherapist or counselling agency / CIC — solo or team — and UK-first defaults matter.
- • Outcome measures matter clinically and PHQ-9 / GAD-7 / CORE-10 (plus CORE-OM, YP-CORE, DES-II, WSAS, Goal-Based Outcomes) need to be first-class, not configuration.
- • Supervision session tracking, CPD logging and supervision-to-expense auto-flow matter for your practice.
- • You run an agency or CIC and want flat pricing that does not scale up with headcount, plus therapist-to-client assignment, shared calendars with room booking, therapist billing management and secure communications.
- • Funding-and-demographic reporting for grant-funded services, dual-code clinical governance, waiting-list workflows or note governance are on your must-have list.
- • You want a native iPhone app for logging notes between sessions.
Sessionly vs WriteUpp: which is right for UK therapists?
WriteUpp and Sessionly both serve UK therapists but from different angles. WriteUpp is an established multi-discipline UK practice management platform with Healthcode insurance-billing integration and a decade-plus user base, best for mixed clinics combining counselling with physiotherapy, osteopathy or podiatry. Sessionly is UK practice management software for therapists, counsellors and counselling agencies / CICs — narrower in scope, deeper in UK-therapy specifics: named outcome measures (PHQ-9, GAD-7, CORE-10, CORE-OM, YP-CORE, DES-II, WSAS, Goal-Based Outcomes), BACP-aligned defaults, dual-code clinical governance, supervision and CPD tracking, funding-and-demographic reporting for grant-funded services, and flat pricing (£10.99/mo solo, £49.99/mo for up to 25 therapists).
Frequently asked questions
What is the biggest difference between Sessionly and WriteUpp?
Focus. WriteUpp is a UK-established practice management platform built for mixed clinics — physiotherapy, podiatry, osteopathy alongside counselling. Sessionly is built exclusively for UK talk therapy: counselling, psychotherapy and counselling agencies/CICs. That focus means Sessionly ships UK outcome measures as first-class features, dual-code clinical governance for agencies, funding pot tracking for CIC-funded work, and BACP-aligned retention defaults rather than configuration steps.
Which is cheaper for a solo therapist?
Sessionly. Sessionly Private Practitioner is £10.99/month (or £109/year). WriteUpp's public pricing sits in the £19.95–£27.95/month range per user depending on tier. Over a year, most solo therapists save around £150–£200 by choosing Sessionly. For a like-for-like walkthrough of monthly and per-team-size totals, see our fuller WriteUpp alternative comparison page.
Which is cheaper for a therapy agency?
Sessionly, particularly as the team grows. WriteUpp bills per user, so a 10-therapist agency typically sits around £200–£280/month and a 25-therapist agency £500–£700+/month. Sessionly's Agency plan is a flat £49.99/month for up to 25 therapists. If you plan to grow the team, the maths does not stay close.
Does Sessionly support Healthcode for insurance billing?
No. WriteUpp integrates with Healthcode so therapists can submit claims for BUPA, AXA, Aviva and Vitality clients directly from the platform. If insurance billing is a large part of your income, WriteUpp is the better fit. Sessionly focuses on self-paying private clients and agency/CIC-funded work.
Can I import my WriteUpp data into Sessionly?
There is no one-click importer today, but the Sessionly team will help you migrate. Email us when you are ready to switch and someone will walk you through transferring your active client list, archiving historical records sensibly, and getting your workflows running. Most therapists run both platforms briefly in parallel during the transition, and the 14-day free trial covers most of that.
