Is FRIDAI Worth It for a LINE-⁠Only Shop? Cost per AI Reply and What a Plan Includes

Split the bill first: what does a LINE shop pay for AI customer service?

Many shops compare different things in the same "monthly fee" column, so the comparison never lines up. Split the bill into three:

The first is a shared cost. LINE Taiwan announced that from 1 November 2026 the plans will be: light usage NT$0, medium NT$1,000 and heavy NT$1,400 per month (before tax). You pay this whichever AI tool you pick, so take it out and compare only the second and third.

Also, according to LINE's developer documentation, content sent as a reply message does not count toward the monthly message quota. A customer asking and the AI answering usually does not use up your broadcast allowance.

Three common options: what does each cost per month?

Prices come from each vendor's official page, checked on 30 October 2026; confirm on their site before buying.

FRIDAI's NT$ prices follow its pricing page: card payments are in US dollars, while PAYUNi and JKOPAY payments are in NT$ at 32 to the dollar, for example Launch monthly NT$2,240 and Launch yearly via PAYUNi NT$20,000.

All three are easy to start with. The difference is how much work one payment buys, so next we turn the monthly fee into a cost per reply.

Number one: how do you work out the cost per AI reply?

The formula is simple:

Cost per reply = AI tool monthly fee ÷ replies the AI fully handled that month

FRIDAI Chat publishes its monthly reply allowance, so you can work it out directly:

Yearly billing means "2 months free": you pay for 10 months and use 12. Launch yearly at NT$20,000 averages about NT$1,667 a month; divided by 500 replies, that is about NT$3.3 each.

For tools without a published reply allowance, use your own numbers: during the trial, check how many replies the AI sent, then divide the fee by that. Tip: count only the replies the AI finished without you adding a line, so the result is your real cost～

Number two: what does the plan actually include?

Cost per reply is half the story. The other half is how much of the work is already in that payment, so you neither buy it separately nor do it yourself.

For a shop that only runs LINE, one FRIDAI Chat plan for LINE messages includes:

LINE's native AI shines at simplicity: when every question has a fixed answer and fits in 100 Q&As, it handles the common questions. 賴管家's main plan brings members, tags and booking management together, with the AI module added as needed. FRIDAI Chat puts answering, follow-⁠up questions, bookings, human handoff and follow-⁠ups into one plan, which suits shops where customers ask back and forth.

Number three: the hours you get back

For a small shop, the most expensive cost is usually the owner's own time. Here is a hypothetical example:

Assume: the owner takes 2 minutes to answer each message
500 messages a month × 2 minutes = 1,000 minutes ≈ 16.7 hours

Hand those 500 messages to FRIDAI Chat's Launch plan and you trade NT$2,240 for about 16.7 hours, or about NT$134 an hour. Swap "2 minutes" for your own shop's real number and the result tells you whether it is worth it for you.

There is also a benefit the monthly fee does not show: late-⁠night and weekend messages get an instant answer. A customer who asks at 10 pm "Do you have a slot tomorrow afternoon?" books on the spot, instead of trying another shop while waiting for your reply the next morning.

Which option fits your shop?

Adding Instagram or Facebook DMs later

Many LINE shops move on to Instagram or Facebook once they grow. FRIDAI charges one plan per platform account: one for LINE messages, one for Instagram DMs, one for Facebook Messenger. The upside is that the same knowledge notebook and rules carry over, so a new platform does not start from scratch.

To turn Instagram post comments into automatic DMs and leads, add FRIDAI Social; see the Instagram comment keyword DM guide.

Try it for 30 days at US$1 and count with real messages

The most accurate way to count is to run a month on your shop's real messages. FRIDAI offers a 30-⁠day trial for US$1 (NT$30 via PAYUNi or JKOPAY) with no lock-⁠in and up to 100 replies during the trial.

During the trial, do these three things:

1. Put your 20 most-⁠asked questions and your price list into the knowledge notebook.
2. Write three rules: when to ask a follow-⁠up question, when to quote, and when to hand over to a person.
3. After 30 days, check the dashboard: how many replies the AI sent, how many you added, how many bookings were made, then plug them into the formula above.

For how to write the rules, follow the six-⁠part template in How to write AI customer service rules.
