WhatsApp payment reminder templates in Thai

A WhatsApp payment reminder in Thai names the order, the amount and the deadline, includes a working payment link, and stays polite. Below are 9 reminders written in Thai for unpaid orders, expiring links, deposits, balances and bank transfers, each with an English gloss. AeroChat sends them while an order is unpaid and detects the payment automatically, so the customer never has to reply “paid” or send a receipt.

What a payment reminder should do

Most unpaid orders aren’t refusals. The customer got distracted, the link expired, or the payment failed. A reminder with a fresh link and a clear deadline brings many of them back.

Be polite and specific. Name the items, the amount and when the order will be released. One or two reminders is enough.

Writing reminders in Thai

Thai shop replies end sentences with ค่ะ or คะ when the voice is female and ครับ when it is male. Pick one voice for your store and use it in every template. The templates below use ค่ะ, and each page includes one ครับ version.

“คุณ” before the customer’s name is polite. Borrowed words such as ออเดอร์ (order), สต็อก (stock) and ไซซ์ (size) are normal in shop chat, so the templates use them.

Many Thai shops ask the customer to send a transfer slip (สลิป) after paying. With a payment link, AeroChat sees the payment from the gateway, so the customer doesn’t need to send a slip and your team doesn’t need to check one.

The variables stay in English, such as {{customer_name}}. AeroChat fills them from your store data when it sends the message.

The WhatsApp rules that apply

If the customer messaged you in the last 24 hours, you can send any of these as a free-text reply. Outside that 24-hour customer service window, a business-initiated message needs an approved template. These messages fit Meta’s utility category when they are about the customer’s own order or account and contain nothing promotional. Meta’s guidelines say utility templates must not promote products, upsell, cross-sell or include offers. A template that mixes an update with a promotion is classed as marketing. See the WhatsApp message templates guide, WhatsApp message templates and template approval.

Meta’s guidelines give a payment reminder for the customer’s own account as a utility example. Keep discounts and “pay now for 10% off” offers out of a utility reminder.

When you create a template, Meta asks you to assign it a language code. For Thai that is th. Meta does not translate templates, so you supply the Thai text yourself. A template with the same name in several languages counts as a separate template for each language.

Send these automatically with AeroChat

AeroChat creates the payment link through your payment gateway, for example Omise or 2C2P, and watches the order in your store platform, such as Shopify, WooCommerce or Wix:

Unpaid order and expiring link: sent at the times you set after the link was created, if no payment has arrived.
Failed payment: triggered when the gateway reports a failed attempt. AeroChat sends a fresh link.
Deposit and balance: amounts and due dates come from the order and the rules you set.
Payment received: AeroChat detects the payment from the gateway automatically and confirms the order in the chat. The customer never has to type “paid” or send a screenshot.
Questions: a customer who replies in Thai about another payment method or a new link gets an answer in Thai in the same chat.

AeroChat never sees card numbers and never holds your funds. See WhatsApp payment reminders and WhatsApp payment links.

Questions

Does the customer need to tell us they paid?

No. AeroChat detects the payment from your gateway and confirms the order in the chat by itself.

Do I need a separate approved template in Thai?

Yes, for messages sent outside the 24-hour window. Meta asks for a language code on each template, th for Thai, and does not translate it for you. Each language version of the same template counts toward your template limit.

What if the customer writes back in English or mixes languages?

AeroChat replies in the language the customer writes in, including messages that mix Thai and English. The template sets the first message, and the chat continues in their language.

Should I use ค่ะ or ครับ?

Use the one that matches the voice of your store. Many shops use ค่ะ by default. What matters is that every template and every reply uses the same one.

Can I add a discount to get them to pay?

Not in a utility reminder. A discount makes it a marketing message. If you want to offer one, send it separately as a marketing template to customers who opted in.
