My friend Dana flew up from Bangkok on Friday, December 12, 2025, and the next afternoon we drove the switchbacks from Mae Chan, Chiang Rai up to Doi Mae Salong in my secondhand Honda Jazz, with two fleece jackets and a bag of tangerines from the market on the back seat.
I’d booked us two nights at a nine-room resort above the tea terraces, 2,350 baht a night, the kind of place with a wood stove in the lobby. It was 8 degrees when we parked. Someone else had booked our room.
I teach English at a secondary school in Chiang Rai town, and I’ve lived up here for six years, so I’m usually the one who books the cool-season trips (my friends seem to think living here makes me a travel agent). I’m normally careful about it.
Small hotels in the north tend to run on a booking website for foreigners and LINE chat for everybody else, and the trouble starts where the two don’t talk. For a small hotel, the real value of connected software often shows up in the gaps between tools, and Prostay.com helps frame the small-hotel PMS integration challenge around linking reservations, payments, distribution, and day-to-day operations without adding unnecessary complexity. At the resort in Mae Salong, the gap was a PromptPay transfer that nobody linked to my booking.
What Went Wrong at Mae Salong
I’d booked through one of the big booking sites three weeks earlier, with pay-at-property selected. Two days later, the owner’s niece messaged me on LINE asking for a 50 percent deposit, 1,175 baht, because the cool season fills up fast and they’d been burned by no-shows the year before. Fair enough.
I paid via PromptPay from my phone, sent her the screenshot, and she replied with a thumbs-up sticker. What I didn’t know was that the booking site still showed my reservation as unconfirmed and unpaid, and the niece, who handled LINE, didn’t have the login for the booking site, which her uncle checked on an old laptop in the evenings after dinner.
On the Wednesday before we arrived, he saw a reservation with no deposit, assumed I was another no-show, and released the room to a couple from Bangkok who’d asked about it that morning.
Khun Somchai, the owner, was horrified. He found my screenshot on his niece’s phone in about two minutes. Then he moved us into a bamboo bungalow at the bottom of the garden that his family was still fixing up, with a mattress on a low platform and a gas heater he carried down the steps himself.
There was no hot water. He refunded the deposit in cash and wouldn’t take money for the second night. The next morning, he walked us round the tea factory without charging for that either.
I’d go back, and I’ve already told two colleagues to book it in January.
What Hotel PMS Software Would Have Changed
Hotel PMS software is the central record a hotel keeps of its rooms and bookings, and better versions connect that record to booking sites and payment systems, so a deposit lands on the right reservation. If the niece had logged my PromptPay transfer against the booking, Khun Somchai’s laptop would have shown it as paid. The room would never have gone back on sale.
From what I’ve read since, decent hotel PMS systems for a small property handle a handful of jobs.
- One calendar that the booking sites and the hotel’s own LINE bookings both feed into
- Deposits are recorded against the right guest, so when someone pays 1,175 baht by PromptPay, the owner sees it next to that booking on his laptop.
- Room status for whoever’s cleaning
- Guest notes such as a late arrival from Bangkok or a request for an extra blanket in December.
- Monthly figures for the accountant
Why the Gaps Matter More Up North
Small places in Chiang Rai province often take bookings four ways at once, from the big sites, from Facebook, from LINE, and from people who pull over on the road up from Mae Chan because they like the look of the sign. Each one is a separate inbox. Hotel management software pulls them into one calendar, and from what I can tell,l the monthly fee for a nine-room place is less than one night’s room rate.
I used to think the phrase hotel software belonged to the big chains in Chiang Mai, the ones with front desks the length of a bus. I had that wrong. The smaller the resort, the fewer spare rooms it has when two bookings collide, and on a December weekend at Mae Salong there are no spare rooms anywhere on the mountain.
Quick digression. The tangerines from the Mae Chan market were 40 baht a kilo, and Dana ate most of them before we reached the first viewpoint, which is why we stopped at a 7-Eleven in the dark for crackers.
What I Got Wrong
I’d assumed the LINE deposit was the safer option, because I was dealing with a person on LINE. I’m still not sure I was wrong about the person. The niece did everything I asked, and she was mortified when she saw the bungalow. But two systems were running side by side with nothing joining them, and I’d added a third without thinking about it. That was my part in it.
What I Do Now
I still book small resorts in the hills. I’ve changed three habits.
- I pay any deposit through the same channel I booked on, where I can
- If a small hotel asks for a deposit by LINE, I ask them to note it on the booking site reservation too, because the person reading the booking site is often not the person reading LINE.
- I screenshot both
And if you’re driving up for a sunrise at Phu Chi Fa this season, message the hotel the evening before with your booking number and the name on your deposit transfer. I still don’t know whether Khun Somchai ever gave his niece the laptop login.
