WeChat for Sourcing: Keep the Quote Outside the Chat

Last fact-checked: November 10, 2026.

The supplier sends the sample photo, the new price, and a picture of a bank card in the same WeChat thread, ten minutes apart. By Friday the proforma still shows yesterday's price and a company account with a different name. The chat is where the work moved. It is not the record you can pay against. This page is about keeping that thread usable. It is not a guide to finding strangers, and it does not state a file-size limit, because the help center linked from WeChat did not open from here on 10 November 2026.

The English WeChat home, opened that day, describes the app as chats, calls, and life services. It is wechat.com. The Chinese home at weixin.qq.com lists a File Transfer Assistant among its tools and also names WeChat Pay as its own entry. The pay product and the chat are not the same thing. How a bank transfer works, once you are ready to pay, is T/T payment. The paper you pay against is the proforma invoice.

WeChat with Chinese suppliers, filed so someone else can read it

Treat the thread as a workshop bench. At the end of the day, lift three things out of it and put them where the order file lives.

• The specification you actually asked for, in the shape of an RFQ with the fields that make quotes comparable. A voice note that says "same as last time, but better zipper" is not that RFQ.
• The sample photos, saved with the date and the booth or company name in the file name. A screenshot buried under forty later messages will not match the carton six weeks from now.
• The quotation, as a file or a written message you can paste under the proforma. If the chat price and the proforma price differ, the proforma is the one you question before you pay. Comparing three of those files is how to compare supplier quotes from China.

After a fair, the same habit applies to name cards and hallway promises. The follow-up that turns them into an order is after the Canton Fair: samples, quotes, and the first order.

Do not let the chat change the price or the account

The failure mode is ordinary. The proforma names a company and a bank. An hour later a WeChat message says the company account is "under audit" and asks you to pay a personal card "just this once." Sometimes the message comes from the same account you have been talking to for a month. Sometimes it comes from a new account that copied the display name. Either way, the payment does not move until the name on the account matches the party you already decided to pay. That check is verify the supplier before you pay.

A changed unit price belongs on a revised proforma, with the Incoterm and the quantity still visible. A thumbs-up under a photo is not a revision. If you are buying at the market and the thread is only the follow-up after you fly home, the floor routine is still how to buy from Yiwu. The market in that guide is in Zhejiang. A venue in Jebel Ali that uses a similar name is a different place.

WeChat is the coordination channel

Use the chat to ask for the missing carton size, to nudge a sample that is late, and to confirm which photo is the approved one. Use the RFQ, the proforma, and the contract for the words that have to survive a dispute: product, quantity, packing, Incoterm, price, and the account name. The WeChat Acceptable Use Policy, last updated on the page as 1 August 2023, treats fraud and misrepresenting your identity as unacceptable use. That is a platform rule about behaviour. It is not a payment guarantee, and it will not refund a wire you sent to the wrong name. The policy is the acceptable use policy. Reports and safety tools sit on the WeChat Safety Center, which opened the same day and does not publish a file-size table.

A short habit before you lock the phone

• Spec copied into the RFQ, not left as a voice note.
• Sample photos saved outside the app, with names you can search.
• Price only paid when it matches the proforma you accepted.
• Account name matched to the supplier check, not to the latest screenshot.
• No file-size number taken from this page. The help center did not open here.

Is WeChat Pay the same as chatting on WeChat?

The Chinese home lists WeChat Pay as its own entry, beside the chat. This article stops at the message. The transfer, when you make one, is the T/T note linked above, against a proforma whose account you have already matched.

Can I skip email if everything is already in WeChat?

You can coordinate there. You still need a file that states the product, the quantity, the price, and the account, in a form someone who never opens your phone can read. That file is the RFQ and the proforma, not the scroll of the thread.

Who runs the file is also covered in How to Choose a China Sourcing Agent, agent fees and the contract, an agent, a forwarder, or a buying office, and where to find suppliers.
