TL;DR
The best booking software for lash technicians charges a flat monthly fee — not a percentage of each set. At £55/appointment and 12 new clients per month, Treatwell's ~42% effective commission costs £277/month vs. £29/month on Nextro. Over a year, that's £2,976 paid to a platform. Every infill client you keep is a client who never goes through the marketplace again — and the commission bill never grows.
Why the commission model is particularly damaging for lash technicians
Lash clients are some of the most loyal in the beauty industry — a client who loves your work comes back every 2–3 weeks for infills, indefinitely. This makes the commission model especially punishing: the platform charges a fee to introduce the client, but then that client — who should become a regular returning every fortnight — goes back to the marketplace for their next booking.
65% of first-time marketplace clients don't return to the same technician. Instead of building a loyal book of regular infill clients, you're perpetually paying commission to acquire new clients to replace the ones the platform kept for itself. The economics of commission are structurally wrong for a business built on repeat business.
Commission cost breakdown for lash technicians
Scenario: average lash set (classic/hybrid) at £55, 12 new clients per month through a marketplace.
| Platform | Commission | Per booking | Monthly (12 new) |
|---|---|---|---|
| Fresha | 20% | £11.00 | £132/mo |
| Treatwell | ~42% eff. | £23.10 | £277/mo |
| Nextro | 0% | £0 | £29/mo flat |
Annual saving over Treatwell: £2,976 kept in your business. That's 54 full lash sets — per year — that you'd have been effectively working for free to cover the platform fee.
The infill model and why it demands direct booking
Lash infills are booked every 2–3 weeks. A client who books through a marketplace for their first set and then books their infill directly with you — using your personal booking link — pays zero commission from that second appointment onwards. Every infill appointment is yours, commission-free, indefinitely.
This is why getting new clients onto your direct booking page from appointment one is so valuable. Share your link at checkout, add it to your Instagram bio, and include it in the booking confirmation. A client who bookmarks your page never needs to return to the marketplace.
Every service type, every style — one flat fee
Classic sets, hybrid, volume, mega volume, infills, removal — most lash technicians offer 6–10 distinct bookable services at different price points and durations. On Nextro, you list every service separately with its own slot length, price, and availability. Clients choose their service and pay upfront. You pay one flat monthly fee regardless of how many services you offer or how many appointments you take.
