How to Connect Your WhatsApp Business Number to a Shared Team Inbox
The steps to connect a WhatsApp business number to Nexus through Meta’s official window, what to prepare first, and what happens to your number afterwards.
WhatsApp inbox + CRM for sellers
Every customer chat in one inbox. Nothing left unanswered.
Nexus connects your business WhatsApp, Instagram and Facebook to one screen. Your team replies together, every customer is saved as a contact, and an AI chatbot helps answer from your shop data.
Free plan: 1 WhatsApp number, 1 agent, 500 contacts. On Android and the web.
Customer chats scattered, replies missed
Sellers who sell over WhatsApp rarely lose orders because of the product. They lose them because the chat sank out of sight.
Chats spread over many phones
One number is held by several people, and messages arrive from WhatsApp, Instagram and Facebook. Nobody knows who has already answered whom.
Forgetting to reply
A customer asking for a price waits for hours, then buys elsewhere. There is no reminder and no follow-up note.
Customers are not recorded
Customer numbers exist only in chat history. There is no list of who bought and who is still deciding.
One place for every sales conversation
From the first message to the customer buying again.
WhatsApp and social inbox
WhatsApp chats, Instagram and Messenger DMs, and Facebook and Instagram comments in one list. Assign conversations to agents, add labels, mark done.
Customer contacts (CRM)
Each customer has a card: chat history, labels, notes and where the contact came from. Import from CSV or Excel, export any time.
Sales pipeline
Follow each lead from asking, to negotiating, to buying. Set follow-up dates so nobody slips through.
Broadcast to opted-in customers
Send template messages to contacts who agreed to receive them, chosen by label. See how many were sent, read and replied.
AI chatbot
Answers customer questions only from your shop data. Start in suggestion mode, switch to automatic when you are ready.
Quick replies and templates
Save the answers you use often, and official message templates for reaching customers outside the 24-hour window.
Start in three steps
No extra gear to install. Your number connects through the official Meta window.
01
Sign up and connect your number
Create a free account, then connect your business WhatsApp number in the official Meta window, with your own permission.
02
Reply from one inbox
All chats land in one place. Invite agents, assign conversations, use quick replies.
03
Follow up and broadcast
Keep customer records, run your pipeline, and message customers who agreed to hear from you.
An AI chatbot that does not make things up
The bot answers only from data you allow: products, prices, stock, opening hours and the status of that customer's own orders.
✓No data: the bot says it does not know and hands the chat to a person
✓Suggestion mode (default): the bot writes a draft, an agent presses send
✓Automatic mode behind your switch, only inside the 24-hour window
✓A customer asks for a person, or complains: handed straight to an agent
Honest limits
!The monthly AI reply allowance follows your plan
!Answers that quote a price or stock level are checked against shop data, and become a draft if they do not match
!If the AI service is down, the bot stays silent and the chat still reaches an agent

WhatsApp guides for business
Connect WhatsApp

Message templates
Write a message template in Nexus, submit it to Meta, and use it to reach customers outside the 24-hour window.
Broadcast limits
Broadcast only to contacts who agreed, within Meta’s per-24-hour customer limit. Nexus shows what is left and holds back the queue.

Questions and answers
Does Nexus use the official WhatsApp API?
Yes. Nexus uses Meta's WhatsApp Business Platform (Cloud API), and your number connects through Meta's own Embedded Signup window. There is no lookalike WhatsApp Web or modified app.
Is there an extra fee per message?
Nexus adds nothing to your messages. WhatsApp message fees are paid directly to Meta at Meta's official rates. You only pay for your Nexus plan.
Which WhatsApp number can I connect?
The number connects through Meta's official window, and Meta sets the requirements for a number. If something is missing, that window shows it before the number is connected.
When may I reply to a customer?
Within 24 hours of the customer's last message you can reply freely. After that, Meta's rules allow only message templates that Meta has approved.
Who can receive a broadcast?
Only contacts who have given permission. Contacts without permission cannot be selected, and opt-outs are respected.
Can the AI chatbot answer wrongly?
The bot answers only from the shop data you allow and hands over to a person when unsure. In suggestion mode an agent always checks before sending.
What if my contacts go over the plan limit?
Chats from new numbers still reach the inbox and can be answered, but are not saved to contacts until you move up a plan.
Is there an Android app?
Yes. Nexus is on Google Play and also works on the web with the same account.
