Payment

How buying works

2

Choose how much to top up

Choose 100 / 300 / 500 THB, or enter your own amount, from 100 up to 100,000 THB.

3

Pay with the PromptPay QR in the system

The system generates a QR code you can scan and pay immediately — no transferring outside the system, no sending a receipt to anyone.

4

Credit is added automatically

Once payment goes through, credit is added to your shop's account automatically and you can start using it right away. The system deducts credit based on actual usage every time, with every deduction shown for you to review.

FAQ

Frequently asked questions

Answers to the things you may be wondering about

LINE OA, Facebook Messenger, Instagram and a chat widget for your website, all managed from the same inbox.

Have your products, services, prices, shop policies and the questions customers ask most often ready. Wasu AI uses these to answer in a way that fits your business.

When the AI meets a question that needs a person, or the customer asks for one, it stops replying automatically and passes the conversation to your team.

Each business's data is kept separate from every other, every request is filtered by your shop ID, and the access tokens for your chat channels are encrypted before they're stored. See our privacy policy for the full details.

Top up credit in advance via PromptPay QR right in the system. Choose 100 / 300 / 500 THB, or enter your own amount, from 100 up to 100,000 THB. Once payment goes through, credit is added automatically.

Deducted from your credit based on actual usage, message by message. No monthly fee, no signup fee. See every deduction in your history.

When credit runs out, the bot stops replying to new messages on every channel. Customer messages still reach your inbox, marked as waiting for a team member, so you can reply yourself. Your balance may dip slightly below zero from replies already in progress. Once you top up, the bot replies to new messages again.
