Beta launch offer

First 10 juristic persons: free 2-month trial, then 20% off for 6 billing cycles, plus a voucher for a free 2-month upgrade to Pro when Pro goes on sale
Numbers 11–20: free 2-month trial, then 10% off for 6 billing cycles, plus a voucher for a free 2-month upgrade to Plus when Plus goes on sale

Upgrade vouchers: during the free upgrade months you pay your current plan price (with the Beta discount if it still applies) and no difference is charged. When the voucher ends, if you want to keep the upgraded plan, you must tell our team (otherwise you return to your current plan automatically with no extra charge). Each voucher can be used once, and you must still be a customer when the voucher plan goes on sale. The Pro voucher of the first 10 may be used on Plus instead if you choose to use it earlier; the Plus voucher of numbers 11–20 is for Plus only.

Applies to juristic persons that go live by 31 March 2027 or until 20 have joined, whichever comes first, counted in order of go-live date.

The discount applies to the monthly plan fee actually used in each cycle, whichever plan you choose (Standard–Max) and even if you move up or down a plan; it continues for all 6 billing cycles and stays with the eligible juristic person. It excludes SMS and the accounting add-on, cannot be combined with the yearly payment discount, and starts with the first billing cycle after the trial.

All 20 Beta customers agree that HaiDaiMai may show their juristic person name as a real use case on this website; the first 10 also agree to the use of their logo and testimonial.

Example: a 100-unit project

80 households on LINE get 4 messages a month (invoice, reminder, receipt, overdue notice): 320 messages, over the 300 free, so at least THB 1,280 / month goes to LINE on top of the software.

HaiDaiMai

With HaiDaiMai Standard, 100 units cost THB 800 / month with LINE included.

Pricing questions

Which plans can we sign up for now?

Standard is available now, with everything needed to collect common fees on LINE, and you can add the accounting service. Plus, Pro and Max open once their features are ready.

Which features can I use in the free trial?

During the free 1-month trial you use the launch feature set (Standard) with your real project data. When it ends, you pick the plan you want — nothing is charged automatically and your trial data carries on.

How are Beta places counted?

Places are counted in order of the date each juristic person goes live, not the date of the request. The first 10 get a free 2-month trial, then 20% off for 6 billing cycles; numbers 11–20 get a free 2-month trial, then 10% off for 6 billing cycles. The first group gets a voucher for a free 2-month upgrade to Pro (usable on Plus instead), and the second group a voucher for a free 2-month upgrade to Plus, each used when the voucher plan goes on sale. The discount applies to the monthly plan fee actually used in each cycle, whichever plan you choose (Standard–Max) and even if you change plan, and continues for the full period. It excludes SMS and the accounting add-on. The offer ends once 20 have joined, or for anyone going live after 31 March 2027, whichever comes first. All Beta customers agree to have their juristic person name shown as a real use case on this website, and the first 10 also agree to the use of their logo and testimonial. The Beta discount cannot be combined with the yearly payment discount.

Which features do Beta customers get?

During launch, every plan uses the same feature set (Standard). Plus / Pro / Max features marked “coming soon” open in stages as planned, and Beta customers get early access.

Which plan should we choose?

Standard covers LINE collection, slip checks and the legally required work. Plus suits offices that want less chasing and reconciling. Pro suits projects that want repair requests, bookings and online meetings. Max suits large projects or management firms that want AI and their own LINE OA.

Which plans can add the accounting service?

Any plan. The accounting service is a flat THB 3,000 a month per project, the same for any project size and not tied to the number of units — management firms pay per project they add it to.

Do condominiums and housing estates pay the same?

Yes. Every plan uses the same tiered formula by number of units, whether rooms or plots.

What do we save by paying yearly?

You pay for 10 months and use it for 12 — roughly 17% off.

How are units counted?

We count the active units in the project register on the 1st of each month — rooms or plots, including vacant units and the developer’s units. Closed or merged units are not counted (the same definition as for backup SMS).

What if we send more SMS than included?

Each plan includes backup SMS per unit per month: 1 on Standard and Plus, 2 on Pro, 3 on Max; anything beyond is billed by usage. LINE and e-mail messages for invoices and receipts are included.

Do prices include VAT?

No. Prices exclude VAT and auditor fees, which the juristic person pays directly as the law requires.

Do we get a discount for referring another office?

A referral and partner programme is on the way — details coming soon.

See the partner program

What happens to our data if we leave?

Your data belongs to the juristic person. Exporting everything as files when you leave is coming soon.
