How the three costs are built
LINE OA: the Pro plan at THB 1,780 a month before VAT, for 29,500 messages. LINE's published packages are Free with 300 messages, Basic with 15,000 and Pro with 35,000. Over three years that is THB 64,100.
Small CRM by hand: Odoo advertises One App Free, one app with unlimited users on Odoo Online. If CRM is that app, there is no per user fee. The sum above adds the optional 4 hour Starter implementation pack at THB 19,000. Odoo's external API sits on the Custom plan only, so this setup has no automatic connection to LINE.
CRM with sync: Odoo's Custom plan for 5 users is THB 81,900 in the first year and THB 102,400 a year after, plus the Starter pack. The LINE to CRM connection is one workflow, which we price from THB 190,000. We priced Odoo because we hold its sourced prices. Other CRMs exist, and we did not price them here.
Change followers, broadcasts and segment size in the LINE OA cost calculator. It runs in your browser and saves nothing.
The trap: sync is where the price jumps
Per user, Odoo Standard lists at THB 11,400 a year and Custom at THB 20,500, before the first year discount. The API is why a sync pushes you to Custom. Add a build on top and the third setup costs several times the first. That is fine when staff spend hours a week copying chats. It is wasteful when they do not.

When LINE OA alone is enough
Stay on LINE alone when most of these are true.
- One or two people answer chats and everyone knows the regulars.
- You sell mostly in person, and LINE is for bookings, reminders and promos.
- Tags, notes and the reward card cover what you track today.
- You do not need to report a sales pipeline to anyone.
Set up tags, notes and reward cards using our guide to a simple LINE customer list.
When a CRM earns its cost
Add one when any of these is true.
- Three or more staff talk to the same customers and lose history.
- You sell high value jobs with a pipeline, quotes and follow ups.
- Customers use more than LINE: email, phone, web forms and walk ins.
- You need purchase history and reports in one place, not in chats.
Keep consent and retention right with the LINE PDPA checklist.
When not to hire us
Do not hire us to connect LINE to a CRM before you have tried the manual route for a month. If tags and a spreadsheet solve it, they are the right answer. Hire us when staff already copy chats by hand every day and the time lost is larger than the build.
See what we set up on the LINE OA service page.
Before you buy a CRM for LINE
- Count the staff who answer customers and the chats they handle a day.
- Time one week of copying chat details into a sheet. That is your sync budget.
- Check which LINE plan your sends need, using the calculator.
- Ask any CRM vendor whether LINE sync needs a higher plan or an API.
- Confirm who owns the customer list and where it is stored.
- Write the consent line shown when a customer adds you.
- Decide the one report the CRM must produce.
- Set a review date after one month on the cheaper setup.
Questions buyers ask
Do I need a CRM if I already use LINE OA?
Not at first. LINE OA has tags, notes, broadcasts and a reward card. Add a CRM when several staff lose history between chats or you need a sales pipeline.
How much does LINE OA cost per month in Thailand?
LINE's published packages are Free with 300 messages, Basic at THB 1,280 and Pro at THB 1,780 a month, both before 7% VAT.
Does Odoo connect to LINE?
Odoo lists its external API on the Custom plan only, so a connection built on that API needs Custom. Check with an Odoo advisor, because a partner connector may work differently.
How are LINE messages counted?
By recipient. A message sent to five people counts as five, and messages that cannot be delivered, for example to someone who blocked you, are not counted. Reply messages are listed as not counted toward the monthly message count.
Who wrote this, how and why
Who: Written by the DLVX team. We set up LINE OA and CRM connections, so we gain when you hire us. We say above when LINE alone is enough.
How: Baht figures come from our LINE OA cost calculator and Odoo cost tool, with euro prices converted at our planning rate and shown before VAT. We opened the LINE, LINE Developers and Odoo pages on 8 November 2026. The tool data is dated 29 and 30 October 2026. The connection price is our published price for one workflow, not a quote. Search results we reviewed on 8 November 2026 were vendor pages with no prices.
Why: Thai business owners are told a CRM is the next step after LINE OA. The pages that say so sell a CRM. We wanted a neutral cost comparison and an honest view of when to wait.
