How to Use Messaging for Your Sole Trader Business

The Accounted Editorial Team·3 March 2026·8 min read

WhatsApp has over two billion users worldwide, and in the UK it's become the default way most people communicate. Your clients are already on it. Your suppliers are on it. That builder you've been chasing for a quote? Definitely on it.

So it makes sense to use WhatsApp for business communication too. But using your personal WhatsApp account for client messages is a recipe for chaos — business enquiries mixed in with family group chats, no professional profile, and no way to set boundaries around when you're "available."

That's where WhatsApp Business comes in. It's a free, separate app designed specifically for small businesses, and it's surprisingly powerful for something that costs nothing. Let's walk through how to set it up and use it effectively as a sole trader.

What Is WhatsApp Business?

WhatsApp Business is a free app (available on iPhone and Android) that looks and feels very similar to regular WhatsApp, but with additional features tailored for business use. You can run it alongside your personal WhatsApp on the same phone — you'll just need a separate phone number for the business account.

If you don't have a second phone number, a cheap pay-as-you-go SIM will do the job. Some sole traders use their existing landline number, which works for verification via a phone call.

Key Features

Business profile — display your business name, description, address, email, website, and opening hours
Catalogue — showcase your products or services with photos and prices
Quick replies — save and reuse frequently sent messages
Labels — organise chats and contacts with colour-coded labels
Automated messages — set greeting messages for new contacts and away messages for out-of-hours enquiries
WhatsApp Web — use the app from your computer for easier typing

Setting Up WhatsApp Business

Step 1: Download and Install

Download WhatsApp Business from the App Store (iPhone) or Google Play (Android). It's a separate app from regular WhatsApp — you'll see "WhatsApp Business" with a slightly different icon.

Step 2: Register Your Business Number

Open the app and register with your business phone number. If you're using a number that's already linked to regular WhatsApp, the app will offer to migrate your existing chats. Think carefully before doing this — it's usually better to start fresh with a dedicated business number.

Step 3: Create Your Business Profile

This is where you make a good first impression. Go to Settings > Business Tools > Business Profile and fill in:

Business name — use your actual trading name
Category — choose the option that best describes what you do
Description — a brief summary of your services (up to 256 characters)
Address — optional, but useful if clients visit you
Business hours — set these to manage expectations about when you'll respond
Email and website — include both if you have them

A complete business profile looks far more professional than a blank one. It also reassures new clients that they're messaging a legitimate business.

Step 4: Set Up Automated Messages

This is one of the most useful features for sole traders. You can set:

Greeting message — automatically sent to anyone who messages you for the first time (or after 14 days of inactivity). Something like: "Hi! Thanks for getting in touch with [Your Business Name]. We'll get back to you within a few hours during business hours."
Away message — sent when you're outside your business hours. This stops clients wondering why you haven't replied at 11pm on a Saturday.

These automated messages are simple to set up and make a real difference to how professional your business appears.

Step 5: Create Quick Replies

If you find yourself typing the same responses over and over — your pricing, your availability, directions to your premises — save them as quick replies. You can then insert them with a keyboard shortcut, saving time on every conversation.

Best Practices for Using WhatsApp Business

Keep It Professional (But Friendly)

The beauty of WhatsApp is that it's informal. You don't need to write like a corporate email. But do maintain a professional standard — reply promptly, use correct spelling, and avoid sending voice notes unless the client clearly prefers them (some people find voice notes inconvenient).

Use Labels to Stay Organised

Labels are incredibly useful for keeping track of where each client or enquiry stands. Create labels like:

New enquiry
Quote sent
Job in progress
Awaiting payment
Completed

You can then filter your chats by label to see, at a glance, which clients need attention.

Don't Mix Business and Personal

This bears repeating: keep your business and personal WhatsApp accounts separate. It's not just about professionalism — it's about your sanity. When you finish work for the day, you can mute or close your business WhatsApp and actually switch off.

Set Boundaries Around Response Times

Just because WhatsApp shows when you've read a message doesn't mean you have to reply instantly. Your business hours exist for a reason. Turn on your away message outside those hours, and don't feel guilty about it.

Use WhatsApp Web for Longer Conversations

Typing long messages on your phone is tedious. WhatsApp Web lets you access your business chats from your computer, which is much easier for detailed conversations, sending documents, or managing multiple chats at once.

Using WhatsApp Business for Marketing

WhatsApp Business isn't just for responding to enquiries — it can be a genuinely effective marketing channel too.

Broadcast Lists

Broadcast lists let you send a message to multiple contacts at once, without them seeing each other's details (unlike a group chat). This is perfect for announcing promotions, sharing updates, or sending seasonal reminders.

The important caveat: recipients only receive broadcast messages if they have your number saved in their contacts. So make sure you ask clients to save your business number.

Status Updates

WhatsApp Status works like Instagram Stories — short posts that disappear after 24 hours. Use it to share behind-the-scenes content, showcase recent work, or promote limited-time offers. It's low-effort and reaches people who already know your business.

Catalogue

If you sell products or services with set prices, the catalogue feature is brilliant. Clients can browse what you offer directly within WhatsApp, without needing to visit a separate website. You can add photos, descriptions, and prices for each item.

Data Protection and WhatsApp

Using WhatsApp for business communication means you're handling client data, which brings GDPR responsibilities. Here are the key things to keep in mind.

Get Consent

Before adding a client to a broadcast list or marketing to them via WhatsApp, make sure you have their consent. This doesn't need to be a formal written agreement — a simple "Is it OK if I send you updates via WhatsApp?" is fine. But do ask.

Be Careful With Sensitive Information

Avoid sending or requesting sensitive personal data (financial details, personal identification numbers, health information) via WhatsApp unless absolutely necessary. While WhatsApp uses end-to-end encryption, it's still a messaging platform — not a secure document exchange system.

Understand WhatsApp's Data Practices

WhatsApp shares certain metadata with its parent company, Meta. While message content is encrypted, information about who you're messaging, when, and how often is not. If data privacy is a major concern for your business, make sure you've read WhatsApp's privacy policy and are comfortable with its terms.

Integrating WhatsApp Business With Your Other Tools

WhatsApp Business works best when it's part of a broader system, not a standalone silo.

Link to Your Website

Add a WhatsApp chat button to your website so potential clients can message you directly. This is often more effective than a contact form — people prefer the immediacy of messaging.

Connect to Your CRM

If you use a CRM (customer relationship management) tool, check whether it integrates with WhatsApp Business. Several popular CRMs now offer WhatsApp integration, letting you log conversations and track client interactions in one place.

Use It Alongside Your Accounting Tools

When a client confirms a job via WhatsApp, you'll eventually need to invoice them. Having a clear workflow — from WhatsApp conversation to invoice sent — keeps things efficient. Tools like Accounted make it easy to create and send invoices quickly, so the transition from "job agreed" to "payment requested" is seamless.

Common Mistakes to Avoid

Spamming Clients

Just because someone has messaged you once doesn't mean they want daily updates. Be respectful of your clients' attention and only send messages that are genuinely useful or requested.

Ignoring Messages

WhatsApp shows read receipts by default. If a client sees you've read their message and you don't reply for days, it looks bad. If you can't reply properly straight away, a quick "Got your message, will get back to you by [time]" goes a long way.

Not Backing Up Your Chats

WhatsApp conversations can contain important business records — agreements, quotes, instructions. Make sure your WhatsApp backup is enabled (via iCloud on iPhone or Google Drive on Android) so you don't lose this information.

Using It for Everything

WhatsApp is great for quick communication, but it's not a project management tool, a file storage system, or an accounting platform. Use it for what it's good at, and use dedicated tools for everything else. Our guide to the best apps for sole traders in 2026 can help you build a well-rounded toolkit.

Is WhatsApp Business Right for You?

If your clients are consumers (B2C), WhatsApp Business is almost certainly worth setting up. It meets people where they already are, it's free, and it makes your business more accessible.

If you work primarily with other businesses (B2B), it depends on your industry and your clients' preferences. Some industries — trades, beauty, fitness, events — have embraced WhatsApp enthusiastically. Others still prefer email. Follow your clients' lead.

Either way, it takes about fifteen minutes to set up, costs nothing, and can make a genuine difference to how professional and responsive your business feels.
