The workspace built for session nail artists.
Day rates, overtime, usage and expenses — invoiced in minutes, in any currency. Built by a Fashion Week session artist who got tired of doing it the hard way.
Start FreeBuilding an invoice from scratch in Canva. Working out overtime on the notes app at midnight. Trying to remember whether that Paris job was billed in euros — and doing the conversion by hand. Nobody teaches you this part, and it costs you money every time you get it wrong.
SessionOS™ turns a diabolical hour into two minutes.
Shoot, prep, fitting, test, travel, half day — each with its own fee. Set your rate once and every day on the job prices itself.
Enter your call and wrap times. SessionOS works out the hours over standard and bills them at the right rate — so you stop giving away your evenings for free.
The part most artists undercharge for, or forget entirely. Add usage terms and fees to any job, itemised clearly on the invoice.
Assistant fees, kit fees, mileage and costs at cost. All tracked against the job and carried straight onto the invoice.
Every job with dates, upcoming first, grouped by month. So you know what's already booked before you say yes to anything else.
Your logo, your bank details, your terms. A clean, professional invoice you'd be happy to send to any production in the world.
Every invoice gets its own number, in order, fixed the moment you send it. The paperwork your accountant expects — without you having to think about it.
Paris in euros. New York in dollars. London in pounds. Choose the currency per job and the invoice comes out right — no calculator, no guesswork.
Build the job on your phone between looks. Send the invoice from your iPad on the train home. Your work follows you.
Each client, with every day rate you've billed them and when. If your last rate was lower than one you've charged before, SessionOS tells you — so you never quote a returning production less than you did last time.
What you've earned since 6 April, what's still owed, what you've been paid all time. The figure you need for Self Assessment, already worked out.
Tap any total to see every invoice behind it — client, dates, amount, what's still outstanding. The number always shows its working.
Export any of those figures as a PDF statement, in the same typeface as your invoices. Something your accountant can actually check, instead of a screenshot.
Editorial. Campaign. Fashion Week. Commercial.
SessionOS™ was built by Nadia Blanco — a session nail artist with 168 credits since 2011 across British Vogue, Valentino, Vivienne Westwood, Harrods, Net-A-Porter, Evian and Diet Coke, and 67 runway credits across all four Fashion Weeks.
Every rate, every fee, every line on the invoice is there because it had to be.
