Who it's for

A personal trainer can invoice their coaching as a light entrepreneur without setting up their own company. You sell the coaching, agree on prices and do the work, and Truster handles the invoices, tax withholding according to your tax card, and reporting to authorities. The account is free and you only pay when you invoice, so you can start coaching with just a few clients alongside your regular job.

#What kind of coaching does a PT do as a light entrepreneur?

The most traditional form is one-on-one coaching at the gym: sessions, programs and tracking progress. Many gyms partner with independent trainers, where the trainer pays the gym rent or a share of sales and invoices their own clients directly. As a light entrepreneur you can work this way at several gyms without your own company.

Alongside one-on-one coaching, popular options include small-group coaching, outdoor workouts, corporate wellness days and exercise groups, as well as remote coaching, where programs and tracking are handled through an app. Remote coaching brings in recurring monthly invoicing and helps even out quieter periods in your calendar.

#Pricing and expenses in coaching work

PT services are typically sold as packages: a set number of sessions or a month-long coaching program that includes programs and tracking. Package pricing builds client commitment and makes invoicing predictable. Companies are often sold day-based packages. The price should cover not just sessions but also program design, communication and your own professional development.

Typical expenses include gym rent or the share paid to the gym, courses and certifications, coaching app licenses, equipment, and travel between clients and gyms. Expenses and mileage are logged in the Truster app and are automatically factored into your pay.

Clients most often find a PT through the gym and social media: client success stories, workout tips and a clear service description bring in inquiries. Partnering with a gym boosts your visibility among its members, and corporate wellness days often lead to individual clients. But the most important channel is results: a client who's making progress recommends their trainer to others.

#Invoicing and pay with Truster

Coaching packages are usually invoiced upfront or monthly, which makes your income regular. Recurring invoices to the same client are created quickly in the app based on the previous one. Maksuvahti tracks your receivables and sends payment reminders to clients on your behalf for €1.99 per invoice.

If a business client's payment takes longer than expected, HetiPalkka pays out your wages even before the invoice due date, for a fee of 5% of the invoice amount. Monthly-plan users get Truster Turva included in the price, so you're covered while coaching sessions at the gym and outdoors.

Light entrepreneurship suits a trainer who wants to build their own client base without the bureaucracy of setting up a company. You can flexibly test out pricing, services and remote coaching, and if your business grows significantly, you can move to your own company later on.

Light entrepreneurship makes coaching work professional without the hassle: your client gets an invoice and a receipt, you get your pay with taxes handled and no bookkeeping to worry about. Compared to salaried gym work, you decide your own pricing and services, and compared to a sole proprietorship, the admin is taken care of for you. You can also flexibly combine part-time gym work with your own coaching business.

Many trainers even out their income by combining in-person coaching with remote clients: when in-person sessions quiet down in summer, monthly invoicing from remote coaching keeps going. Log every coaching package with its agreed price in the app, and you'll see your monthly invoicing at a glance and notice in good time when a fixed monthly fee becomes more cost-effective than a percentage-based one.

#How much do you actually take home?

Truster's service fee is 3.99% of your invoicing, or a flat €55/month, which suits someone running a full coaching calendar. The service fee and statutory payments are deducted from the invoice amount, and tax is withheld from your pay according to your own tax card. VAT is usually added to invoices for coaching services at the general rate of 25.5%.

Of the service fee options, the percentage-based 3.99% suits a part-time trainer, while the flat €55/month suits a full client roster. Price your packages so they also cover program design and communication between sessions, not just the hours spent at the gym.

The exact amount you take home depends on your invoicing volume, expenses and tax rate. On our Calculators page you can try different package prices and client numbers and instantly see how much lands in your account.
