hisalon

hiSalon is appointment booking software for salons, beauty parlours, spas and grooming studios in India. It runs inside WhatsApp, so clients book without installing an app, creating an account or calling the salon. When a client messages the salon’s WhatsApp number, hiSalon replies with a tap-to-book menu. The client chooses a service, stylist, day and time, and the booking goes straight into the salon’s calendar. Only free slots are shown, and holidays and each artist’s day off are skipped, which prevents double bookings. Owners and managers use a single dashboard to track revenue, visits, no-shows and client ratings. They can send appointment reminders on WhatsApp in one click and add walk-in or phone bookings by hand. The salon keeps using its own WhatsApp number, linked by scanning a QR code. hiSalon helps salons that lose customers to missed calls and manual scheduling take bookings around the clock without extra staff.

HoldATime

HoldATime is simple, affordable reservation software for organizations that manage shared spaces and resources. Schools, HOAs and residential communities, clubs, parks, recreation facilities, churches, and other organizations can use HoldATime to manage reservations for tennis and pickleball courts, parking spaces, meeting rooms, clubhouses, pools, equipment, and other reservable resources. Administrators can create amenities with one or multiple reservable units—for example, a pickleball facility with Courts 1–4 or a parking area with individually numbered spaces. Each amenity can have its own booking rules, including reservation duration, advance-booking windows, usage limits, buffers, group restrictions, recurring reservations, and optional approval requirements. HoldATime automatically prevents conflicting reservations for the same resource. Users see live availability and reserve an available time from their phone or computer without contacting an administrator. Organizations can also post QR codes at courts, rooms, parking areas, or other facilities so users can quickly access the appropriate reservation page. Confirmed reservations can include a QR pass for convenient on-site verification. HoldATime is designed to replace spreadsheets, paper calendars, email chains, and other manual reservation processes without requiring organizations to purchase a large facility-management or industry-specific platform. Administrators can import users from a spreadsheet, control who is allowed to book, and manage different types of shared resources from one system. Organizations can start with HoldATime's free plan, which includes unlimited amenities and users, up to 50 future reservations, and a 14-day advance-booking window with no credit card required. Paid plans are available for organizations that need additional reservation capacity and features.
