Everything that matters
happens in 24 hours

Keep guest details and arrival tasks together, from confirmation through check-in.

On booking

The link goes out

Confirmation carries the guide. Nothing to install, nothing to remember.

Before arrival

They register themselves

Passports, dates of birth, nationalities. Typed by the people who know them.

0h

They walk in

Door code, Wi-Fi, and where the boat leaves from are already on their phone.

24h

TM30 is filed

The deadline immigration counts from arrival, and the one you cannot miss.

What it does

Six jobs that live in LINE today

01

Check-in before arrival

Guests fill in their details from the link in their confirmation, so nobody stands at a desk copying a passport by hand.

02

TM30 without the scramble

Every arriving guest is tracked against the 24 hour deadline, and the file immigration asks for is one download.

03

A guide that answers itself

Door code, Wi-Fi, how the air conditioning works, when the boat leaves. Written once, read in seven languages.

04

Tours and add-ons

Your own trips and transfers, priced and requestable from the guide, landing in the admin as a request.

05

Room service

A menu on the phone the guest already has open, charged to the room bill.

06

Balances and deposits

Take the rest of the stay before arrival or settle it at the property. Stripe handles the card.

TM30

The filing nobody wants
to be late on

Thai immigration wants every foreign guest reported within 24 hours of arrival. Kohsta groups arrivals by what has to happen next, names what is missing from whose passport, and produces the Inform Accommodation file per registered address.

  • Waiting on details, ready to file, filed, nothing to report
  • Hours to deadline on every booking, counted from arrival
  • One file per registered address, split at their row limit
  • Filed references kept so you can prove it later

Pricing

One plan.
Everything included.

Choose your number of rooms to see the price. Every feature is included in every band.

A room type counts as the rooms behind it. Three Deluxe Doubles is three, not one. A room you have switched off counts as nothing at all.

Questions we are asked

Does this replace my channel manager or booking engine?

It can connect directly to supported channels such as Agoda when partner access is approved. Trip.com and other channels can be connected through Cloudbeds. Channel bookings are changed at their source; Kohsta is not a guest booking engine.

Does Kohsta submit the TM30 for me?

It prepares the file in immigration's own Inform Accommodation format, one per registered address, and tracks the deadline. The upload happens on their site, and you mark the booking filed afterwards.

Will guests see the Kohsta name?

Your guide and guest emails carry your property name, logo and colours. Guest emails have a small Powered by Kohsta line at the bottom.

What languages does the guide speak?

English, Thai, German, Spanish, Swedish, Malay and Chinese. Guide content you write yourself can be translated in the admin.

How long does setup take?

A property with its rooms, guide content and one registered address is usually running the same week. We import what you already have where we can.
