Customer stories

Less admin after coaching—in their own words.

Customer review

I wasn’t keen on paying for another app, and getting all my clients set up did take a bit of time. But three months in, I’m getting the monthly invoices done in about half an hour rather than three or four hours. I log the lessons as I go, so I’m not trawling back through messages at the end of the month, trying to work out who I’ve taught and when.

Customer review

I work for myself — I’m not running a big academy. I teach one-to-ones and small groups, and I do all the admin myself. I don’t need a complicated system for running a whole organisation. I just need to keep track of my lessons and get the invoicing right. FlexTrainer fits the way I work.

Customer review

I’ve been using FlexTrainer for eight months now. Logging a lesson is straightforward enough that I still do it after a long day on court. That’s what makes the difference for me.
