A friend left her job to start her own business as a cosmetic laser specialist. She decided to establish a private, professional spa and hired estheticians and LMT's. She owns iPhones and iPads, and purchased a 24" iMac (her first Mac). She uses "Square" for payment transactions and plans on purchasing the new "Square Stand POS" paired with a USB cash drawer and scanner with an unused iPad 4. I helped determine her short and long term needs, recommended ISP services and discussed options. I configured a new Airport Extreme Base Station with 2.4/5GHz/Guest networks and clean installed 10.9. I recommended a 2-bay Synology NAS for site hosting, business database, security system and OS X "Time Machine" wireless backups (Synology systems are reasonably priced with a plethora of great apps/services). The challenge is finding the right OS X business management software. All three need access to a single database for client information, appointments, individual business accounts, inventory tracking and sales, POS integration, off-site access via mobile devices/VPN's, etc. My first thought was "FileMaker Pro 12 Advanced" as it is a fully customizable system for tracking inventory, appointments/schedules, clientele database, invoices, reports, etc. The free iOS apps seem to allow quick access to the shared database. POS integration is also important in order to sync product sales and services between "Square" and "FileMaker Pro 12 Advanced" or another management system. If anyone has any advice and/or recommendations, I'd greatly appreciate the help. Thanks!
