nǐ xiǎng yòng shénme fùkuǎnfāngshì?

Mandarin word order here is:

subject + 想 + 用 + 什么 + noun

So the sentence is built like this:

• 你 = you
• 想 = want / would like
• 用 = use
• 什么付款方式 = what payment method

A very common pattern is:

想 + verb phrase

So 想用 means want to use.

Also, in Chinese, question words like 什么 usually stay in the same place where the answer would go. So:

• Statement: 你想用银行卡付款。 = You want to use a bank card to pay.
• Question: 你想用什么付款方式？ = You want to use what payment method?

Chinese does not move 什么 to the front the way English moves what.

In this sentence, 想 means want to or would like to.

It is softer and more natural than a very direct 要 in many service situations.

Compare:

• 你想用什么付款方式？ = What payment method would you like to use?
• 你要用什么付款方式？ = What payment method do you want to use?

Both are understandable, but 想 often sounds a little gentler and more conversational.

Yes, 付款方式 already means payment method, but 用 is still important because the sentence is asking which method you want to use.

So the logic is:

• 用 = to use
• 付款方式 = payment method

Together:

用什么付款方式 = use what payment method

Without 用, the sentence would sound incomplete or unnatural.

Because 什么 is directly modifying the noun 付款方式.

This is similar to saying:

• 什么人 = what person / who
• 什么东西 = what thing
• 什么问题 = what question
• 什么付款方式 = what payment method

So 什么 + noun is a very common structure in Chinese.

It is best treated as a set phrase meaning payment method.

You can break it down like this:

• 付款 = to make a payment / pay
• 方式 = method / way

Together:

• 付款方式 = method of payment / payment method

Even though it is built from smaller parts, learners usually memorize it as a common chunk.

Historically and grammatically, 付款 is a verb-object expression meaning to make payment or to pay. But in 付款方式, it works like the first part of a compound noun.

So in this sentence:

• 付款方式 behaves as a noun phrase: payment method

This kind of thing is very common in Chinese. A verb-like element can help form a noun compound.

Yes. 支付方式 also means payment method and is very common.

The difference is small:

• 付款方式 feels very natural in everyday speech and service situations.
• 支付方式 can sound slightly more formal or more common in written language, apps, websites, and business contexts.

In real life, both are widely used.

For example:

• 您想用什么付款方式？
• 您想用什么支付方式？

Both are fine.

Because 付款方式 itself is a noun phrase, and 什么 can directly modify it.

So:

• 什么付款方式 = what payment method

You do not need a classifier here.

If you wanted, you could also say:

• 什么样的付款方式

This means something like what kind of payment method, but it is a little longer and less direct. In many situations, 什么付款方式 is more natural.

Yes, it is neutral and perfectly acceptable, especially in a store, restaurant, or service setting.

But it is not especially formal. To make it more polite, you could say:

• 请问，您想用什么付款方式？

This adds:

• 请问 = may I ask
• 您 = polite you

That version sounds more respectful, especially when speaking to customers.

Yes. In many customer-service situations, 您 is better because it is polite.

Compare:

• 你想用什么付款方式？ = casual / neutral
• 您想用什么付款方式？ = polite

If you are talking to a friend, 你 is fine.
If you are speaking to a customer, older person, or someone you want to address respectfully, 您 is usually preferred.

Individually:

• 你 = third tone
• 想 = third tone

When two third tones come together, Mandarin usually changes the first one in pronunciation. So 你想 is commonly pronounced more like:

• ní xiǎng

The written tones do not change in pinyin spelling here, but the actual spoken sound often does.

This is called third-tone sandhi.

Usually yes, but its exact English translation depends on context.

In this sentence, 什么付款方式 means what payment method.

In other contexts:

• 你吃什么？ = What are you eating?
• 这是什么？ = What is this?
• 你想买什么颜色？ = What color do you want to buy?

So 什么 is very flexible, just like what in English.

Yes, and it is very natural.

• 你想用什么付款方式？ = What payment method would you like to use?
• 你想怎么付款？ = How would you like to pay?

The second one is shorter and more conversational. The first one is a bit more explicit because it specifically mentions payment method.

Both are common.

Yes, very often, especially in conversation.

For example, a cashier might simply ask:

• 想用什么付款方式？
• 用什么付款方式？
• 怎么付款？

Chinese often leaves out subjects when they are obvious from context. If the cashier is clearly speaking to you, there is no need to repeat 你.

Usually the answer would name a payment method, often after 用:

• 用现金。 = Cash.
• 用信用卡。 = Credit card.
• 用微信支付。 = WeChat Pay.
• 用支付宝。 = Alipay.
• 刷卡。 = By card / I’ll use my card.

You can also answer in a fuller sentence:

• 我想用信用卡付款。 = I’d like to pay by credit card.

Yes, it is natural and correct.

That said, in real-life speech, native speakers may choose shorter versions depending on the situation, such as:

• 怎么付款？
• 您怎么付？
• 您想怎么付款？

Your original sentence is still perfectly good, especially when the speaker wants to sound clear and professional.
