WhatsApp Business Account Setup: Step by Step
You've decided to stop running your business off a personal WhatsApp account. Good call — the green "Business" badge, a real profile, a greeting that fires when you're asleep. The trouble is that "set it up properly" turns into thirty minutes of guessing which settings matter and what you might be locking yourself out of later.
This is a clean WhatsApp Business account setup walkthrough for a small team or solo owner. You'll get from a fresh install to a finished, professional profile, with the settings most people miss flagged along the way. At the end, we'll be honest about where the free app stops working — so you don't have to redo this in three months.
TL;DR: the setup, in five moves
- Download WhatsApp Business (separate app) and register with the number you want customers to message — a fresh number or your personal one, but pick deliberately.
- Build the profile that customers actually read: name, category, description, hours, address, website.
- Turn on the automations that pay for themselves: greeting message, away message, quick replies.
- Add a catalog if you sell products, and your business labels to keep chats organized.
- Know the ceiling. The app is built for one phone, one person — plan for what happens when that isn't enough.
Step 1: Download the right app and choose your number
The most common mistake is installing the wrong app. WhatsApp Business is a separate download from regular WhatsApp — search the App Store or Google Play for "WhatsApp Business" (a green speech bubble with a "B"). You can't run both apps on the same number on the same phone, so decide which number this account will use before you register.
Your options:
- Use your existing personal number. WhatsApp offers to migrate your chat history when you register. Fine for a solo owner whose customers already message that number — no new SIM, nothing to announce. The trade-off: business and personal now share one inbox on one phone.
- Use a fresh, dedicated business number. Cleaner separation, but you have to tell everyone the new line. Best when you're starting fresh or want work off your personal phone entirely.
Whichever you pick, register it like any WhatsApp account: enter the number, confirm the SMS or call OTP, and accept the terms. If you're weighing the official app against API tools at this stage, our WhatsApp Business vs WhatsApp Business API breakdown explains which one actually fits a small team — the answer surprises most people.
Step 2: Build a business profile people trust
A complete profile is the cheapest credibility you'll ever buy — when someone lands on your chat, it's what tells them you're real. Open Settings → Business tools → Business profile and fill in every field; empty fields read as "abandoned."
- Business name. Permanent-ish (WhatsApp limits changes), so use your real, customer-facing name, spelled the way people search for it.
- Category, description. Pick the closest fit, then one or two plain sentences on what you do and who you serve — a clear answer to "am I in the right place?"
- Business hours. Set them honestly; they pair with your away message so off-hours customers aren't left hanging.
- Address, email, website, photo. Add a map pin only if customers visit; a live website link beats a phone number; use a square, high-resolution logo, not a blurry crop.
We go deeper on what to write in each field in our WhatsApp Business profile best practices guide. Spend ten extra minutes here — it's the part customers actually see.
Step 3: Turn on greeting, away and quick replies
The free app gives you three light automations. They're the difference between "a person who sometimes replies" and "a business." Find them under Settings → Business tools.
Greeting message
Fires automatically the first time a new contact (or someone who's been quiet for 14+ days) messages you. Use it to set the tone and the response-time expectation:
"Hi, thanks for messaging [Business]! We've got your note and will reply within a few hours during business hours (10am–7pm). For anything urgent, call 0XXXXXXXXXX."
Away message
This is the one most people skip, and it's the most valuable. It auto-replies when you're closed so a 11pm enquiry doesn't sit in silence until morning. Schedule it to "Outside business hours" so it lines up with the hours you set in Step 2. For copy you can lift directly, see our WhatsApp greeting and away message examples.
Quick replies
Save canned answers to the questions you type all day — pricing, location, "are you open?" — and recall them with a "/" shortcut. Set up five or six for your most common questions and you'll claw back real time every single day.
A note on expectations: these are rule-based, not smart. The greeting fires on a schedule and the away message is a fixed string — no routing, no understanding of what the customer asked. Fine at low volume; just know the ceiling so you're not surprised by it.
Step 4: Add a catalog and set up labels
Two more tools worth the few minutes, especially if you sell products.
Catalog (Settings → Business tools → Catalog) lets you list items with a photo, name, price and description, so customers browse without you copy-pasting product shots into every chat. If you take orders this way, our WhatsApp catalog for D2C guide shows how to run it without chaos.
Labels are your only real organization tool in the free app. Tag chats — "New lead," "Paid," "Follow up," "VIP" — to colour-code your inbox. They're per-phone and basic (no shared view, no reporting), but for a solo owner they beat scrolling. Keep the set small.
Step 5: Lock down the settings most people miss
A few minutes here prevents headaches later.
- Two-step verification. Settings → Account → Two-step verification. Set a PIN — your single best defence against losing the number to a SIM-swap or hijack. Non-negotiable for a business line.
- Short link & QR code. Settings → Business tools → Short link gives you a
wa.melink and a scannable QR for your bio, ads, packaging and storefront — the easiest way to turn views into chats. More in our WhatsApp click-to-chat links guide. - Linked devices. You can mirror the account onto WhatsApp Web to type from a keyboard. Useful — but it's mirroring one account, not multi-user access. Everyone sees the same screen, which is exactly where the free app's limits start.
That's it. Profile, automations, catalog, labels, security — your account is properly set up and looks like a real business.
What's next: when one phone isn't enough
The setup above is built for one person on one phone — the design of the free app, and perfectly good when you're solo and your volume is manageable.
It stops working the moment a second person needs in. There's no shared inbox — one phone holds the account, so two teammates can't answer at once without passing a device around. WhatsApp Web just mirrors the same session: no "who's handling this chat," no assigning, no internal notes. And there's no CRM underneath — no contacts database, no deal pipeline, no follow-up reminders. Leads live in the chat list until they scroll away.
If that sounds familiar, the question isn't "how do I set up the app better" — it's "what do I move to next." We cover that head-on in is the WhatsApp Business app enough for teams?, and the bigger picture lives in our pillar, the complete guide to WhatsApp for business.
Where Tenashi fits
When the free app runs out of room, most teams reach for a WhatsApp Business API tool (WATI, AiSensy, Interakt). But the API means a new sending number, template approvals, per-message fees, and — critically — no access to groups at all. It's a heavy switch for a team that just needs more than one person answering.
Tenashi is a lighter answer: the WhatsApp workspace for teams, on your existing number. You link the number you just set up with a QR scan — no new SIM, no porting — and your whole team works one shared inbox that includes DMs and groups. Under every chat sits a real CRM: contacts with custom fields, a drag-and-drop deal pipeline, and follow-up reminders so leads don't go cold. You also get assignment, internal notes, a support desk with tickets and SLAs, and safe broadcasts — instead of labels stuck on one phone.
Because it's your own number, there are no template approvals and no per-message fees — a flat price from $18/mo. Sends are ban-protected (human-paced, warmed up, with duplicate and burst blasts paused before they ship), which reduces risk to your number — though no tool can guarantee against WhatsApp's policies. On Growth and Scale plans, AI can draft suggested replies, summarize a noisy group thread, run OCR on an image and translate messages inline.
There's a 3-day Growth trial, no card.

FAQ
Is WhatsApp Business free to set up?
Yes. The WhatsApp Business app is a free download for Android and iPhone, and setting up your profile, greeting, away message, quick replies, catalog and labels costs nothing. You only pay if you later move to the WhatsApp Business API or a workspace tool for team and CRM features the free app doesn't offer.
Do I need a new number for WhatsApp Business?
No. You can register the WhatsApp Business app with your existing personal number — WhatsApp even offers to migrate your chat history. A separate number gives cleaner work-life separation but means telling customers a new line. Either works; choose before you register, since switching afterward is a hassle.
Can I use WhatsApp Business and regular WhatsApp on the same phone?
Yes, but not on the same number. Each app needs its own number, so you'd run your personal account in regular WhatsApp and your business account in WhatsApp Business with a second number. Most dual- SIM phones handle this fine. You can't run both apps off a single number simultaneously.
How do I set up an away message in WhatsApp Business?
Open Settings → Business tools → Away message, toggle it on, write your text, and set the schedule to "Outside business hours" so it matches the hours on your profile. It then auto-replies whenever you're closed, so after-hours enquiries get an immediate acknowledgement instead of silence.
Can two people use one WhatsApp Business account?
Not really. The free app is built for one phone, one person. WhatsApp Web mirrors the same single session, so there's no true shared inbox, chat assignment or internal notes. For multiple agents on one number, you need a WhatsApp workspace like Tenashi that adds a shared inbox on top of your existing number.
What's the difference between WhatsApp Business app and API?
The app is the free, one-phone tool you set up yourself, ideal for solo owners. The API is a developer platform for higher volume — it needs a separate number, template approvals and per-message fees, and can't access groups. A workspace like Tenashi sits between them: team features on your existing number, no API.
You've set the account up the right way — now make sure it can grow with you. When one phone stops being enough, start a free trial and put every chat, group and lead into one shared workspace, on the number you already have.
