Tepia builds booking and scheduling marketplaces where customers reserve time with many independent providers, such as stylists, trainers, instructors or studios. Each build generates open slots from provider hours, service lengths and buffers, syncs both ways with Google Calendar and Microsoft Outlook, and blocks double bookings at the database level.
In a booking marketplace the inventory is time, and every slot shown to a customer has to be truly free when they tap it.
Tepia computes open slots from working hours, service length, buffers and travel time, then subtracts events synced from outside calendars.

Tepia connects to Google Calendar and Outlook through their APIs so a dentist visit on a stylist's phone instantly blocks that hour.

A short hold during checkout plus a database constraint on overlapping times means two customers can never land in the same slot.

When someone cancels, the next person on the waitlist is offered the slot by push and SMS, and it books itself if they confirm in time.
Mobile and retention figures Tepia plans around when scoping booking marketplaces.
Google's 2016 mobile speed research found 53 percent of mobile visits are abandoned when a page takes longer than three seconds to load.
Pew Research Center reports about 90 percent of US adults own a smartphone, the device most customers use to book.
Tepia clients report about 90 percent customer retention, which matters when repeat bookings drive a marketplace.
A product marketplace sells items that sit on a shelf. A booking marketplace sells hours that disappear if nobody claims them, and each hour depends on a person’s real life. A personal trainer works Monday, Wednesday and Saturday mornings, needs fifteen minutes between clients, travels to some sessions, and has a dentist appointment on her phone calendar next Tuesday. Tepia builds the availability engine to respect all of that before showing a single open slot.
Resources add a second layer. A salon booking needs a stylist and a chair. A climbing gym class needs an instructor and a wall section. A recording studio needs a room and an engineer. Tepia models these as resources that must all be free for a slot to appear, which is what separates a real scheduling marketplace from a calendar widget.
Time zones are the third trap. Online lessons, virtual consultations and providers who travel can put the customer and provider in different zones, and daylight saving changes shift recurring bookings. Tepia stores every booking in UTC with the provider’s zone attached and renders local time for each person.
Most booking disputes come from rules that were never written down. Tepia captures them during Discovery and turns each into a setting providers or your operations team can adjust:
| Rule | Example | How it is implemented |
|---|---|---|
| Service length and buffer | A 45 minute massage plus 15 minutes to reset the room | Slot generation adds the buffer so back to back bookings never overlap cleanup |
| Lead time and horizon | Book at least 4 hours ahead, no more than 60 days out | Per provider limits applied when building the slot list |
| Cancellation window | Free cancellation up to 24 hours before the session | Card on file with a late cancellation charge applied automatically after the window |
| No show handling | Client never arrives for a lesson | Provider marks a no show, which triggers your policy and a note on the client record |
| Recurring bookings | Every Thursday at 6 pm for ten weeks | A series with individual exceptions, so skipping one week does not break the rest |
| Group capacity | A yoga class capped at 18 mats | Seat counts with a waitlist that promotes automatically on cancellation |
| Deposits | Half up front for a bridal hair and makeup booking | Partial charge at booking, balance captured after the appointment |
Under the hood, Tepia often uses PostgreSQL range types with an exclusion constraint so the database itself refuses two overlapping bookings for the same provider or room, even if two customers tap at the same moment.
Booking marketplaces live on repeat use, so the everyday features matter more than the launch splash. Tepia typically scopes:
For booking specific verticals, see beauty and salon booking apps and venue and event space booking. Tepia can also add an AI scheduling assistant that books by chat or phone using the same availability engine.
Tepia’s six phases adapt to booking work by testing the availability engine as hard as the screens.
Discovery typically runs 1 to 3 months, shorter if you arrive with clear booking rules, development and QA 2 to 6 months, and launch about a month. See our process.
If you are one business taking appointments, standard scheduling software or a booking widget on your site is usually enough, and Tepia will say so. A marketplace is a different product: many independent providers, customers comparing them, payments split between the platform and each provider, and your brand on top.
Custom work makes sense when your vertical has rules generic tools cannot express, such as shared rooms, travel between appointments, multi session programs or deposits tied to the service type. It also makes sense when you need the marketplace and each provider’s private calendar to stay in sync without double entry. Read our scheduling software development page for single business scheduling, see our work, or talk to Tepia about your providers and their calendars.
