Which Contract Suits a Physiotherapist Best in 2026

Three real options for formalising a physiotherapist's contract (and when each one applies)

You've just found the physiotherapist who fits your clinic. Now comes the question that paralyses many clinic directors: an employment contract, self-employment or a service agreement? The answer doesn't depend on what you'd prefer to pay, but on how that person will actually work in your centre.

These are the three legal routes available in Spain in 2026. Each has its own conditions, costs and risks if applied incorrectly.

Employment contract (employee)

This is the right option when the physiotherapist works fixed hours, uses your premises, sees your patients and follows your protocols. In that case, there is a clear relationship of dependence and the contract must be an employment contract, with no exceptions.

As the employer, you take on Social Security contributions, monthly payroll, holiday and sick leave. The reference collective agreement is that for Clinics and Consultations of Specialist Doctors or that for Healthcare Establishments for Hospitalisation, Care, Consultation and Clinical Analysis Laboratories, depending on the autonomous community (region).

The real cost of an employed physiotherapist exceeds their gross salary by 30% to 35%. If your centre has a stable turnover and you need guaranteed diary occupancy, this is the safest formula and the one that causes the fewest problems in an inspection.

Self-employed or freelance physiotherapist

It works well when the collaboration is occasional, specialised or complementary. For example: a physiotherapist who runs pelvic floor sessions two afternoons a week, with their own patient list and their own way of working.

In this case, the physiotherapist invoices for their services, manages their own social security and has no imposed schedule. The relationship is commercial, not employment-based. But be careful: if in practice they work like an employee, the relationship is still an employment one, even if the paperwork says otherwise.

There is also the figure of the TRADE (Trabajador Autónomo Económicamente Dependiente, an economically dependent self-employed worker), which applies when a self-employed person invoices more than 75% of their income to a single client. It carries specific rights that you should know about before signing.

Service agreement (arrendamiento de servicios)

This is the model many clinics use to let a treatment room or space to an external physiotherapist who works independently, with their own diary and their own patients. The physiotherapist pays rent for the use of the space or works under a percentage-per-session scheme.

When properly structured, it is perfectly legal. The problem is that in practice many centres use it as a disguised substitute for an employment contract, and that has serious consequences.


The false self-employed physiotherapist: the mistake that triggers the most inspections

The Labour Inspectorate (Inspección de Trabajo) knows the pattern perfectly well. A physiotherapist who is registered as self-employed but works every day in your clinic, with your diary, your patients and your materials. That isn't a commercial relationship: it is a disguised employment relationship.

The five indicators used by the Labour Inspectorate

  • Fixed hours imposed by the clinic. If you tell them what time they have to be there, control lies with the employer.
  • De facto exclusivity. If 90% of their income comes from your centre, the economic dependence is obvious.
  • Use of the centre's premises and materials. Massage table, ultrasound machine, electrotherapy: if they are yours and they always use them, the link is an employment one.
  • Patients brought in by the clinic, not by them. If they are «your patients», not theirs, the working relationship is with you.
  • Integration into the centre's organisation. They take part in team meetings, follow your protocols and appear on your website as a team member.

If several of these indicators are present at once, an inspection can reclassify the relationship as an employment one. The consequences include retroactive payment of contributions, penalties and a surcharge on benefits if there has been sick leave or an accident.

How to protect yourself through the contract

A well-drafted service or collaboration agreement must make clear that the physiotherapist organises their own time, is free to work with other centres and bears the financial risk of their activity. It isn't enough for it to be written on paper: it has to reflect reality.

The recommendation we at ZeeClip give to clinic directors is always the same: have the contract reviewed by an employment adviser who specialises in healthcare before signing it. The cost of a consultation is insignificant compared with that of an inspection that ends in an infringement report.


How the contract model affects the day-to-day management of your clinic

This is the question almost no article answers. Because the type of physiotherapist contract you choose doesn't just have legal implications: it radically changes how you manage the diary, invoicing and payments.

The most common scenario we see in physiotherapy clinics

A clinic with three physiotherapists, two employed and one self-employed. The diary is managed through WhatsApp and Excel. Each therapist handles their own appointments. The result: unfilled gaps, patients calling a personal number, last-minute cancellations without notice and invoices that don't get issued on time.

When that centre implements ZeeClip, the first thing that happens is that each therapist has their own online diary linked to the central system. Patients book directly from their mobile, without calling and without an app to install. The receptionist stops acting as a human switchboard.

Automatic reminders and fewer no-shows

Centres that switch on ZeeClip's automatic WhatsApp reminders reduce their no-shows by up to 40%. In a clinic with three physiotherapists charging €40 a session, that can mean recovering between €800 and €1,200 a month that used to be lost without warning.

The automated workflow works like this: the patient books, receives immediate confirmation, and 24 hours beforehand receives a reminder with the option to confirm or cancel. If they cancel, the slot is freed up in the online diary and can be filled by another patient on the waiting list.

Electronic invoicing according to the employment model

Here the contract model matters directly. If the physiotherapist is self-employed, they issue their own invoices. If they are an employee, it is the clinic that invoices the patient. In both cases, since 2025, electronic invoicing with Verifactu or ticketBAI (Spanish tax-compliant invoicing systems) has been mandatory for most centres in Spain.

ZeeClip integrates electronic invoicing compliant with Verifactu and ticketBAI directly into the workflow: when the session is closed, the invoice is generated, electronically signed and recorded. No manual steps, no numbering errors, no invoices forgotten in a drawer.


Frequently asked questions about the physiotherapist contract

How long does it take to set up ZeeClip in my clinic?

The initial setup takes between 24 and 48 hours. Each therapist's diary, the services, the prices and the automatic reminders are up and running before the week is out. You don't need technical knowledge or an IT team.

Does it work with my current management software?

ZeeClip works as a central platform or alongside other systems. If you use Excel, Google Calendar or basic management software, migration is straightforward. If you have doubts about compatibility with your current system, the technical team will assess it during the no-obligation demo.

Can my patients book from their mobile without downloading an app?

Yes. ZeeClip's automatic booking system works from the mobile browser. The patient opens your clinic's link, chooses a therapist, day and time, and confirms. No downloads, and no prior registration if you don't want it.

What happens if the patient doesn't confirm the appointment?

The system sends a second automatic notification. If the patient still hasn't confirmed before the deadline you set, the slot can be released automatically or marked as pending so that reception can follow up with a call. You decide the flow.

How do I manage the diary of a self-employed physiotherapist who has their own patients?

In ZeeClip you can set up independent diaries per professional, with full or partial visibility for the rest of the team. A self-employed physiotherapist can manage their own appointments within the system without their patient data being mixed with the centre's. The patient history is kept separate.


Choosing the right physiotherapist contract is the first step. But the second, which makes the difference between a clinic that grows and one that stagnates in chaos, is having the digital infrastructure to manage that team without friction. A full diary, patients who don't forget to come, invoices issued in line with regulations and a healthcare CRM that remembers each patient's history.
