Work — ChillHill ERP
ChillHill is a management system built for hair salons and beauty studios. Booking, checkout, inventory, staff performance, customer records, and daily cash flow all live in one place — from opening the shop to closing it out. It's the largest system I've built independently. It's deployed and in pre-launch acceptance testing with a 13-person hair and tattoo salon, where it will replace the salon's current POS; the production cutover hasn't happened yet.
What running a salon on spreadsheets and memory looks like
Each pain point mapped to a system that runs on its own
Customers pick a time and service directly in LINE; a bot writes the booking straight into the system and handles confirmation. Reminders go out automatically before each appointment, cutting down on no-shows and the dead time of waiting for someone who isn't coming.
Each customer has a standing profile — past color and perm history, preferences and things to avoid, photos and notes from every visit, full purchase history. When a different stylist picks up the appointment, a quick look brings them fully up to speed before the customer even sits down.
Every checkout, deposit, and refund is logged automatically. What came in today, what went out, how each stylist is performing — all visible on demand, with cash, transfer, and other payment methods broken out separately so reconciliation has a paper trail instead of a guess.
Stylists log materials used per service, or let standard usage auto-fill for common services; retail sales deduct stock automatically. When something runs low the system flags it, and — with your sign-off — sends the reorder straight to the supplier's rep. When stock arrives, it's checked against the original order before being received.
Front desk handles booking, check-in, and checkout. Stylists see their own schedule, their customers, and their own performance. Owners see full shop-wide cash flow, staff performance, inventory, and reports. Each role's view is scoped to their own work — cost figures and other people's numbers never leak across accounts.
Revenue is attributed to the stylist who performed the service, and the split is recorded the instant checkout happens — not reconstructed later. Stylists can check their own numbers anytime, so what they did and what they're owed is never in dispute at month-end.
Built-in reporting surfaces customer trends, revenue share by service, slow hours, and top-selling products. For a faster answer, you can ask the system directly — "which service had the best repeat rate last month?" or "what needs restocking right now?" — so pricing, staffing, and promotion decisions are backed by numbers instead of a hunch.
Salons with their own retail line — haircare, styling products, merchandise — can run an online storefront from the same system, sharing one inventory with the physical shop instead of managing two separate stock counts.
Four shapes of salon business it's built to fit
Single-location salons
Already has a steady customer base and staff, wants the back office cleaned up.
Growing salons
Scaling from a solo operator to a multi-person team, needs one consistent way to run things.
Multi-service studios
Runs hair, scalp treatment, nails, or tattoo services side by side under one roof.
Branded salons
Has its own product line and wants in-store and online sales managed as one operation.
Staged on purpose — nothing turns on all at once
Confirm services, pricing, stylist roster, payment methods, and current stock counts.
Start with booking, check-in, add-on, and checkout — the four actions used every day — until the team is comfortable and the data setup is confirmed correct.
Front desk learns booking and checkout, stylists learn their schedule and material logging, owners learn reporting and settings. Nobody has to learn more than their own job.
Once the internal flow is steady, switch on LINE self-booking, reminders, and the online storefront.
