Your WhatsApp Business profile is the first thing a customer sees when they open a conversation with your business. Before they read your message, before they see your products — they see your profile picture, your business name, and your About section. In 139 characters or less, your About section must communicate who you are and why you are worth trusting.
Most Sri Lankan businesses either leave the About section blank or write something generic like "Available for orders." This guide shows you how to make every part of your WhatsApp Business profile work harder for your business — from your profile photo to your description to your business hours.
The 6 Profile Elements to Optimise
1. Profile Photo
First visual impression — visible in every customer's contact list
Use your business logo or a clean, recognisable brand image — not a personal photo unless your personal brand is integral to your business (e.g., a solo consultant). The image should be clear and readable at small sizes (it appears as a small circle in contact lists).
What works: Clean logo on plain background · Single product hero shot · Professional headshot (for personal brands only)
What to avoid: Group photos · Busy backgrounds · Blurry images · Seasonal images that you will forget to update
2. Business Name
Appears at the top of your profile and in contact searches
Use exactly the name customers already know. If your Facebook page is "Nila's Homemade Cakes," your WhatsApp Business name should match — or be a very close abbreviation. Consistency across platforms builds recognition and trust.
Adding a brief descriptor after your name can help: "Nila's Cakes | Colombo" or "ABC Photography | Weddings" — if the character limit allows. This is especially useful when customers have multiple businesses in their contacts.
3. About Section
Maximum 139 characters — your most constrained and most important bio field
139 characters is roughly 2–3 short sentences. Every word must earn its place. Focus on: what you do, where you serve, and one CTA. Leave out anything that does not immediately answer the customer's question "is this business relevant to me?"
Formula: [What you do] | [Service area] | [Key differentiator] | [CTA if space allows]
4. Business Hours
Sets customer expectations and triggers your away message automatically
Set your business hours to reflect when you actually respond — not just your official operating hours. If you reply to WhatsApp messages until 9PM even though your "business" closes at 6PM, set 9PM as your end time. Your away message fires automatically outside these hours, so accuracy here directly affects customer experience.
Be realistic — it is better to under-promise and over-deliver than to set hours you cannot keep.
5. Website Link & Product Catalogue
Reduces enquiries by giving customers self-serve information
If you have a website, add the URL to your WhatsApp Business profile — it appears as a clickable link in your profile. If you do not have a website, add your Facebook page URL instead.
Also build a product catalogue in WhatsApp Business (Settings → Business Tools → Catalog). Once set up, you can share your entire catalogue or individual products in any conversation with one tap — replacing the need to type out prices repeatedly.
6. Business Address (if applicable)
For physical locations — adds trust and discoverability
If you have a physical shop, salon, studio, or office, add your address. It displays on a map in your profile and signals that your business is real and established. For home-based businesses in Sri Lanka, adding your general area (e.g., "Nugegoda, Western Province") rather than your full home address is appropriate.

Generate Your WhatsApp Bio in Seconds — Free
The free Business Bio Generator on Toolex.lk creates a 139-character WhatsApp About section for your business — in Sinhala, English, or mixed. Optimised for the character limit automatically.
Generate My Bio →WhatsApp's 139-character limit counts emojis as 2 characters each. Draft your About section in your phone's notes app, which shows the character count, before pasting it into WhatsApp Business. Aim for 100–130 characters to leave a small buffer. Use emojis to replace words where possible — 🚚 instead of "delivery", 🌿 instead of "natural".
Conclusion
Your WhatsApp Business profile is working every time a customer views it — whether or not you are online. A complete, well-written profile with a clear About section, accurate business hours, a product catalogue, and a good profile photo creates an immediate impression of professionalism and trustworthiness that generic profiles simply cannot match.
