WhatsApp Business Setup Checklist for Overseas Sales

The short version #

WhatsApp is not a "drop a button on the site" channel. It's where most of your overseas inquiry pipeline actually starts. Picture the path. A buyer clicks the WhatsApp button on a service page, lands in a chat with a pre-filled message, your salesperson sees the UTM-tagged opener, replies inside 24 hours, tags the lead, and files it in CRM. Break any link in that chain and the keywords, content, and ads upstream all lose their ROI. This piece walks through setup in that exact order. Pick App or Business Platform. Write the profile. Build the catalog. Set up auto-replies. Generate short links and QR codes. Organize multi-user access. Then nail down SLAs and archiving. The table at the bottom is the version you can print and stick next to the sales desk.

A typical situation we run into. A client of ours, an industrial fasteners exporter, launched their English site with a floating WhatsApp button on every service page. By week three, GA4 showed eighty-plus button clicks and the sales team had logged three inquiries. The gap wasn't WhatsApp's fault. The salesperson was using a personal account with a team-photo avatar. The display name was the company's pinyin. A "Do you have CE certificate?" got buried under WeChat notifications on the export manager's phone. This guide is for that situation. Not a download tutorial. Treating account setup as a sales workflow.

1. App vs Platform #

Meta ships two WhatsApp products for businesses. The names are nearly identical and the use cases are not.

• WhatsApp Business App: free, mobile-first, fits one salesperson or a small team. One phone number can be shared across up to five devices. Profile, Catalog, quick replies, greeting and away messages, labels, all included. Most small to mid-sized export teams should stay here.
• WhatsApp Business Platform (API): paid, billed per conversation, accessed through a Meta BSP (Business Solution Provider). Built for high-volume conversation flows, CRM sync, chatbots, and template messages. Jumping straight to Platform for a five-person sales team is over-engineering.

A simple decision rule. If your sales is mostly one-on-one, your team is under five people, and monthly conversation volume is below ~1,000, start with the App. Move to Platform only when volume forces ticket assignment, or when you need conversations to flow into HubSpot or Salesforce. Migration is one-way during the cutover window and the same number cannot run both products at once, so picking wrong upfront costs real time. The official comparison page lays out the differences cleanly. Worth ten minutes before you commit.

2. Profile #

The profile is the first thing a buyer sees after they save your number. Overseas buyers actively click into the profile to see if the company is real, so no field gets to be empty.

• Display name: full English company name. No pinyin, no nicknames, no emoji. Example: Mansion Tech, not Mansion 满想. WhatsApp's name-change review takes seven days, so set it correctly the first time.
• Avatar: clean logo on solid background. Not a team photo, not a product shot. Identical to your website, LinkedIn, and X.
• About: 120 characters max. State what you do, who you serve, where you are. Example: "B2B website and SEO for Chinese companies going global. Based in Shanghai. Reply within 24h on weekdays." Skip phrases like "empowering global clients." Overseas buyers read that as filler.
• Description: 256 characters. Room to spell out core services, target markets, and hours.
• Website: link to a specific service page or your homepage, with https://. If you use UTMs, add them here so traffic from the profile is attributable.
• Address: real office address. Buyers will Google your company; an address that does not match makes them assume a shell.
• Business hours: write them in a way the buyer can convert easily. Example: "Mon-Fri 09:00-18:00 GMT+8", and mention the timezone in the About field too.

For aligning fields across channels, see the Overseas Social Profile Consistency Checklist. Your About on the website, WhatsApp, LinkedIn, and X should read like one company, not four.

3. Catalog #

Catalog is the WhatsApp Business App's built-in product/service directory. Basically a lightweight mini-site inside the chat. Even if you sell services rather than physical goods, build one. Two reasons. First, the buyer sees your full service list without leaving WhatsApp. Second, the catalog link can be sent in one tap, replacing "please check our website at xyz."

For a service company, configure it like this.

• One entry per core service: Website Rebuild, Overseas Site Launch, SEO/GEO Audit, Maintenance and Growth.
• Title each entry with the term buyers search for. "Website Rebuild Service" beats "Service Package One."
• Each entry needs a clean cover image (1:1 ratio, no text watermark) and 80–150 words of description.
• If you do not want to publish prices, fill the price field with "Quote on request" rather than leaving it blank.
• The "Link" field should point to the matching service page on your site, e.g. /solutions/going-global-it.

Once the catalog is live, buyers can open your profile during a chat and tap into the catalog directly. Salespeople can also Send catalog in one tap, or send individual entries.

4. Auto messages #

The App ships with three types of automation. Configure all three and you solve the most painful problem on this channel: buyers messaging while sales is asleep.

• Greeting message: fires on first contact. Short, in English, tells the buyer you saw them, when you'll reply, and how else to reach you.

  Hi, thanks for reaching out to Mansion Tech. We usually reply within 4 working hours (Mon–Fri, GMT+8). For urgent items, you can also email info@mansion.tech.

• Away message: fires outside business hours. Don't reuse the greeting verbatim. Buyers who message during the day and again at night should see different copy, otherwise it reads as a bot.

  We're off for the day. Your message is logged and we'll reply first thing tomorrow morning (GMT+8). If you need a quote, feel free to share the spec, we'll prep it overnight.

• Quick replies: store frequent sales responses behind / shortcodes. At minimum:
  • /intro — one-line company intro plus service page link
  • /quote — quoting process plus the info you need from the buyer
  • /cases — links to two or three relevant case studies
  • /meeting — calendar booking link
  • /closing — thank-you, next step, signature

Quick replies aren't about turning sales into a robot. They free up the rep's typing time so they can actually read what the buyer asked.

5. Short links and QR codes #

WhatsApp's short link format is https://wa.me/<country-code+phone>?text=<URL-encoded message>. That single URL does several jobs.

• Website button: paste the short link into the floating WhatsApp button on your homepage, service pages, and case study pages. Pre-fill a context-rich message: "Hi, I came from your website's case studies page and would like to know more about [project name]."
• QR code: trade show name cards, PDF quotes, email signatures. The Business App generates a QR code natively, but the generated code carries no UTM. If you need attribution, wrap the wa.me URL in Bitly or your own short-link service first.
• UTM: add utm_source=whatsapp&utm_medium=button&utm_campaign=service-page so a salesperson can read the source from the buyer's first message (assuming you pre-filled it) and GA4 can split the traffic.

For the website-button side of this, how to embed it, track clicks, and tie it to inquiries, see How to Add WhatsApp to a Company Website. For UTM naming conventions, see UTM Tracking for WhatsApp, X, Forms, and Email Leads.

6. Team access #

The App lets one phone number link to up to five devices (one phone plus four linked devices). That's enough for a small team, but a few traps.

• Bind the primary device to a company phone, not a salesperson's personal handset. The day they leave, the number leaves with them.
• Name your linked devices. Each device shows up in settings; clean out departed teammates regularly.
• First-touch ownership rules. The biggest problem with a shared number is double replies and dropped leads. A simple rule: whoever sees the message first posts "I'll take this" in the internal sales channel and tags the conversation.
• Labels: the free tier gives you 20. Configure at least: New Lead, Quoted, Follow-up Week 1/2/4, Won, Lost-Price, Lost-Fit, Spam. Tag every conversation. Two weeks in, untagged threads become unreadable noise.

If your team is bigger than five, or you want conversations to flow into a CRM with ticket assignment, that's the moment to migrate to Business Platform or use a compliant third-party tool like Sleekflow or Wati.

7. SLA and archiving #

The most common dropped link in the chain is "buyer messaged, no one picked it up." Two non-negotiables.

• Response SLA: agree internally on replies within 4 working hours, and by 10 a.m. the next morning for off-hours messages. Put that promise in the greeting message and next to the WhatsApp button on the website. Buyers respect a clear expectation more than a fake "instant reply."
• Archiving: do not leave conversations stranded in the App. Once a week, export or screenshot the conversations that closed (won, quoted, lost) and log them, with their labels, UTM source, and outcome, into your CRM or a Lark sheet. Two months in, when leadership asks "how many inquiries did WhatsApp deliver and what's the conversion rate?" you'll need numbers, not vibes.

For how WhatsApp slots into the broader inquiry-response chain (form, WhatsApp, email, CRM), see Inquiry Response Workflow.

8. Privacy and compliance #

Overseas buyers are a lot more privacy-sensitive than domestic ones. A few hard lines.

• No mass promotional broadcasts. WhatsApp punishes unsolicited marketing aggressively, up to permanent number bans.
• Do not add buyers to group chats. Use Broadcast lists or the Channels feature for one-to-many announcements, and get the buyer's explicit opt-in on first contact.
• Don't request sensitive documents (passports, business licenses) inside chat. If the deal genuinely needs them, route the buyer to encrypted email or a compliance portal.
• GDPR and local privacy law sit with your legal team, but the basics need to be drilled into sales. What they say in chat is part of your compliance posture.

A day in sales #

Here's what the eight sections look like in motion. Suppose you're the export manager on a Monday morning.

1. 9:00 — Open WhatsApp Business App. Three weekend messages. Greeting fired automatically, so all three buyers know to expect a Monday reply.
2. 9:15 — First one's from a German buyer. Came in via the service-page button. Pre-fill says "I came from your case studies page." You reply with /intro plus a sentence specific to their industry, label New Lead.
3. 10:30 — They follow up: "Can you send me a sample quote?" You hit /quote, then Send catalog for the Website Rebuild entry.
4. 14:00 — A returning lead asks for case studies. /cases sends three links, all UTM-tagged.
5. 18:00 — Before you log off, screenshot today's closed conversations into Lark and update CRM. The Monday weekly report shows leadership "3 new inquiries, 1 in quoting, 1 closed-won," not "WhatsApp had clicks."

Every section above gets used. Skip one and the chain leaks somewhere.

FAQ #

Can we just use a personal WhatsApp? #

It works in the short term and breaks in the medium term. Personal accounts have no Catalog, no quick replies, no auto messages, no labels. Worse, when the rep leaves, the number and the chat history go with them. Set up the Business App on day one, on a company phone or company number.

Can Business App and Platform run side by side? #

No. One number, one product. Migrating from App to Platform requires a Meta BSP, a 24-hour cutover window, and a period during which the number cannot send or receive. So calling the volume right at the start matters. See WhatsApp's official FAQ on migration.

Does avatar mismatch across channels really matter? #

Yes. Buyers Google a company and look at the website, LinkedIn, and WhatsApp profile in parallel. If the avatar, company name, or About are different in three places, the first read is "is this a scam, or is the rep moonlighting?" Update all three any time the logo or name changes. The Overseas Social Profile Consistency Checklist covers the alignment process.

Does the auto greeting come across as cold? #

Not if it reads like a person wrote it. Buyers know they messaged a business; an auto reply tells them "you've been seen, here's when you'll hear back." What feels cold is silence. A 30-hour gap with no acknowledgement is what kills the lead.
