Sen is the all-in-one platform for nail salons & spas — 24/7 online booking, a smart team calendar, point of sale with tip splitting, and reports that pay your techs right.
Tap appointments onto the ticket, split tips to the penny, redeem points and gift cards. Cash, card, Venmo and Zelle all ring up the same way.
Your end-of-day payout sheet: every ticket per tech with tip shares — by day, week, month or any range.
Your booking link works from Instagram, Facebook, Google and Yelp — confirmations, reschedules and reminders included.
A column per tech and the whole day in one screen. Drag to reschedule, hide whoever is off, and see whose turn is next.
Phone, visit count, yearly spend and last visit — sorted however you like, with notes, loyalty points and full history one tap into any client.
Win-back nudges, birthday offers and time-to-rebook texts — send a one-off campaign or turn on autopilot and let it work.
Expected sales, occupancy, the week ahead and today's full schedule — the moment you open the app.
Rows are ordered by what a salon actually pays — the list price plus the priced extras drawn beside it. Published list prices as of September 2026, before card processing. Booksy charges $29.99 for the first tech and $20 a month for each one after, with no published cap; Fresha charges $14.95 per bookable team member and Mangomint $120 per location plus $10 per user. Striped amber segments are the monthly extras with a published price, add-ons or spending the contract requires; one-time fees and extras without a published price are named but not drawn, and so are marketing, website and SEO retainers — MAC's and Fastboy's alike — which are separate services, not what a salon needs to run its book. Fastboy's striped segment is 3,000 texts at their 2.5¢, the volume our price covers. Fresha's marketplace fee and Booksy's Boost commission are both drawn at ten new clients a month on a $40 first visit; a salon that brings its own clients pays less, one that leans on their marketplace pays more, and Boost is opt-in. In fairness to Booksy, its price includes unlimited appointment reminders and 2,000 marketing texts a month. MAC's bar is their entry package at $288; their best seller is $380 and their top package $475. Those packages bundle marketing we do not sell — social posts, a website and SEO — so the software-for-software gap is narrower than the bar makes it look. Sen’s bar is $49 a month, the price when card processing runs through us; without it Sen is $149 a month for up to 10 techs, and $6 a month for each tech after that.
Built with real salon owners, for the way a nail salon actually runs. Works on the front-desk tablet, your phone, and every tech's phone.
Day, week & month views per tech, drag-and-drop rescheduling — even on your phone — recurring appointments, blocked time and vacations.
One booking link that works everywhere — Instagram bio, Facebook page, Google Business Profile, Yelp. Clients pick services and their favorite tech, see live openings, and reschedule themselves. Deposits, waitlists and no-show tracking included.
Ring up multiple clients & techs on one ticket, suggested or custom tips, tax, retail products, receipts and a void-protected register.
Reminders clients can answer, with replies in a front-desk Inbox. Time-to-rebook nudges, birthday offers and win-back texts that send themselves — at most one message per client per day.
Loyalty points, gift cards, prepaid packages and membership discounts — all included in the price, not sold as paid add-ons.
Every register line per tech with tip shares — your end-of-day payout sheet. Owner, manager and tech roles, with an activity log that shows who did what.
We move everything for you, free — your clients, appointment history and service menu are in Sen before your first day. And your data stays yours: export it anytime, no lock-in.
Thinh Van, founder. Onboarding is invite-only and done with you — your team, service menu and booking link are set up together.
We don't stop at software. BT Co.AI Corp helps your salon get set up with card terminals and payment processing that plug straight into the register — with honest, transparent pricing.
Your first month is free. After that it is $49 a month when your card processing runs through us — or $149 a month without it, the same software either way, for the whole salon. At $49 there is no per-tech fee; at $149 the price covers up to 10 techs and each tech after that is $6 a month. Everything is included: booking, calendar, point of sale, texting, loyalty, payroll and more. No setup cost, no contract, cancel anytime. Card processing is priced separately.
Yes, and it's free. We migrate your clients, appointment history and service menu for you — we've moved salons with over 100,000 appointments without losing a record. Your data stays yours, and you can export it anytime.
No. Sen runs in the browser on the front-desk computer or tablet you already have, and on every tech's phone — nothing to install. Card terminals are optional and only come into play if you use our merchant services.
Yes — the whole app switches between English and Tiếng Việt with one tap, so you and your techs can each work in the language you prefer. This website too.
The app texts clients automatic appointment reminders, and their replies come back to a two-way Inbox at the front desk. You can also turn on marketing autopilot — time-to-rebook nudges, birthday offers and win-back messages that send themselves.
Tell us about your salon and you'll be taking online bookings the same week. Questions first? Send a note — we'll reply within one business day.
Both run the same salon. Pick either — you can switch once you are inside.
