Deposits, PromptPay, and paying as a foreigner at Bangkok nail salons

Why deposits exist

Many salons — especially small private studios run by one nailist — ask for a deposit to confirm a booking.

• Typical amount: 100 to 300 THB.
• Local term: มัดจำ (mat-jam).
• How it works: usually deducted from your final bill, and in most cases refundable if you cancel with reasonable notice (often 24 hours).

The reason is simple: a single-operator studio loses a whole slot to a no-show, so a small deposit filters out bookings that will not turn up. This is normal practice, not a red flag. The flip side is that deposits are exactly why a no-account visitor can get stuck — so it is worth sorting payment in your very first message rather than at the door.

How PromptPay works (and why it's a wall)

PromptPay is Thailand's instant bank-transfer system, used by sending money to a phone number, ID number, or a QR code. It is how most deposits and a lot of full payments are settled.

The catch for visitors is that sending via PromptPay requires a Thai bank account. Most short-term visitors do not have one, and foreign banking apps generally cannot scan or pay a local PromptPay QR directly — which is the whole problem when a studio asks for a deposit over chat.

Payment options without a Thai bank account

Ask which of these the salon accepts before you book, in your first message:

1. Pay in full, in cash, on the day — no deposit

Many larger and mall-floor salons will hold a booking without a deposit, or take walk-ins. This is the simplest path for visitors. Carry the full service amount plus a little buffer in cash.

2. Card payment

Mall-floor salons and higher-end private studios often take credit cards; some add a small processing fee. Smaller community salons frequently do not take cards at all.

3. A card payment link

Some salons can send a card-payment link for the deposit instead of PromptPay. Worth asking.

4. Foreign apps via PromptPay

Apps like Wise or Revolut can sometimes route into a Thai account, but support is inconsistent against live merchant QR codes and changes over time — do not rely on it as your only plan.

If a studio only takes a PromptPay deposit and offers nothing else, it may simply be hard to book as a short-term visitor. That is a systemic constraint, not the salon's fault, and the index has plenty of card- or cash-friendly options. The where to find nails guide notes which areas skew toward mall-floor versus deposit-only studios.

Tipping

Tipping in Thai nail salons is appreciated but not obligatory, and there is no fixed percentage the way there is in some countries.

• Customary: rounding up, or leaving 20 to 100 THB for a service you were happy with — more for long or intricate work.
• No tip is fine: it is not an insult, especially at a fixed-price mall counter.

At mall and higher-end salons, tips left on a card terminal may be shared across staff rather than going to your nailist. If you want it to reach the person who did your nails, hand them cash directly. You do not need to manage any of this — a thank-you and a small tip if you wish is enough.

Avoiding misunderstandings

Two small habits prevent most payment friction.

First, confirm the deposit method and the total expected price in your first message, not on arrival — the booking phrase guide (also in Japanese and in Traditional Chinese) has the phrasing.

Second, if you need to cancel, say so with as much notice as you can. The deposit norm of 24 hours' notice is covered in the phrase guide, and giving notice is what keeps a deposit refundable and a studio willing to book you again.
