LINE OA for shops: thousands of friends, used as nothing more than an inbox
Tuesday afternoon, a salon owner opens her LINE OA and sees thousands of friends. Most of the chats went quiet the day the customer's hair was done. And she's thinking of paying for ads to find new customers.

Key points
- People who add your shop on LINE have already shown interest or used your service. They're easier to reach again than new customers from ads.
- A greeting message and rich menu in LINE OA can answer the first questions customers usually ask, like prices, booking and directions, without anyone typing.
- Tagging customers and adding notes in chat tells you who had what done and when, and what message they should get.
- Frequent broadcasts to everyone get you blocked. Messages to the right people at the moment they need you work better.
- How many messages you can send and what LINE OA costs depend on your plan. Check the latest details with LINE directly.
Three o'clock on a Tuesday afternoon, the quietest hour of the week at the salon. The owner sits down between clients and opens the LINE OA app on her phone. Her friend count is in the thousands, more than she remembered.
She scrolls through the chats. Most are the same messages. "How much is colouring?" "Anything free on Thursday?" "Where exactly are you?" The shop replied, the customer came, the hair got done. The last message in the chat is from the customer, "love it, thank you", followed by a sticker. Then silence. Some chats have been quiet for three months, some for nearly a year.
The people who had their hair coloured three months ago probably have roots showing by now. Nobody from the salon has messaged them. Meanwhile, the owner is wondering whether to try paying for ads this month to find new customers.
We see this all the time with shops on LINE Official Account. Plenty of customers add the shop as a friend, and the shop uses the account as nothing more than an inbox.
People who add your shop on LINE have already raised their hand
To add a shop on LINE, someone has to care enough to tap "add friend". Most have asked about prices, booked, or already been in. Compared with someone who scrolls past an ad in their feed, these people know you, trust you to some degree, and open LINE every day.
The trouble is that most shops always wait for the customer to message first. LINE OA ends up working like the shop phone: if it rings, you answer, if not, nothing happens. Yet it can reach people who'd be glad to come back, if you send the right thing to the right people at the right time.
Before thinking about finding new customers, look at the list you already have. The bigger picture of getting customers as a local business is in finding customers online as a local business.
Greeting messages and rich menus can answer the first question for you
People who've just added a shop usually ask three things: how much, when are you free, and where are you. If every one of those waits for a stylist with colour on her gloves, some customers won't wait.
The greeting message is what LINE OA sends automatically when someone adds you. Use it to say what you do, roughly what things cost and how to book. That beats a plain "thanks for adding us".
The rich menu is the row of big buttons at the bottom of the chat. Put the buttons customers actually need there: prices, book, map, see our work. People can find the answer themselves right away, instead of typing a question and waiting.
Auto-replies can respond when a customer types certain words, so typing "price" sends back your price list. Use them for simple questions that always get the same answer. For anything where you need to see someone's hair first, a person should reply.
Tag customers in chat and you'll know who should get what
A friend list in the thousands only becomes useful once you know who's who. In the LINE OA chat screen you can tag each customer and add notes, for example "colour", "straightening" or "regular", plus a short note on what they had done, when, and which shade.
Do it each time a customer leaves. It takes under a minute, but three months later you can see straight away who had colour when, and who's due a message about their roots. A customer who gets "Hi Mint, you had the golden brown done at the start of July, your roots are probably starting to show. We have a slot this Saturday" feels remembered, not like she's been sent the same promo as everyone else.
The right person at the right moment beats broadcasting to everyone every week
Shops that start messaging customers through LINE OA often get the timing wrong. They broadcast a promotion to everyone, every week. The customer who had her hair done yesterday gets a colouring discount, male customers get a nail promotion, and before long people start blocking. Once someone has blocked you, nothing you send reaches them.
Also worth knowing: how many messages you can send each month depends on your account's plan, and LINE can change its plans and prices. Before planning a lot of messages, check the latest details on LINE's own pages. Sending fewer, better-targeted messages costs less and keeps people from blocking you.
Do the maths for an imaginary salon. Two months ago, 40 customers had their hair coloured. Message each of them when they hit the two-month mark, and say just 10 come back for a root touch-up at 1,200 baht each.
10 customers × 1,200 baht = 12,000 baht from 40 messages
No discount, no ad spend. Just a message at the moment they were going to need you anyway. For how to answer when people ask about prices so they don't vanish mid-chat, read why customers go quiet after asking the price.
Coupons and reward cards in LINE work when there's a reason to come back
LINE OA has coupons and reward cards built in. A salon gets more out of a reward card on services people repeat often, like a wash and blow-dry or a treatment, than on something they do once in a while, because customers can see the card actually filling up.
A coupon should have a clear reason behind it, like a birthday, or a welcome back for someone you haven't seen in a while. Hand them to everyone all the time and customers start waiting for coupons, and your regular prices begin to look expensive.
When chats outgrow your hands, let a system take the repetitive part
If only a few people message each day, everything above can be done by hand in the LINE OA app. But once chats pile up and you have several stylists, questions about free slots and prices eat the whole day at the front desk, and anyone who messages at 10 pm waits until morning.
That's where woowey can build a system for a monthly fee: a bot in LINE that answers questions about prices and opening hours, a booking system where customers pick their stylist and time and get reminders on LINE, and customer records kept in one place. That gives you time to message the customers who should come back, instead of typing prices all day.
The next Tuesday afternoon, the same owner opens her LINE OA again. This time she doesn't just scroll through old chats. She filters the customers tagged "colour" from two months ago and messages them one by one. By evening, three have replied asking for a slot this Saturday.

Ten past ten on a Wednesday night, a customer asks how much a facial costs. The next morning the clinic replies with one line. She reads it and never answers. The number was right. It just left her three more questions to ask.

Seven on a Friday evening, someone in a car park scrolls through three restaurants and picks one in under a minute. The better place two streets away didn't lose on the food. It lost on the phone screen.

Sunday evening, the engine light comes on mid-traffic. The driver pulls over and types "garage near me". The garage that gets the job isn't the best or the closest. It's the one whose Google Maps listing tells the truth.
