Clients send bills to your firm's linked WhatsApp number. Pragma files a bill against the client its **sender** is bound to: the client's own mobile, not the number the firm receives on. A bill from a number nobody has bound is held for a person to assign instead of being guessed at. Only an **Owner** links the firm's number and sees **Settings → WhatsApp intake**. An **Owner**, or a **Manager** assigned to the client, binds senders on the client's **Setup → Intake** tab. ## Link the firm's number **1. Check the connection status** Open **Settings → WhatsApp intake**. Under **WhatsApp number for this firm**, the badge reads **Connected**, **Linking**, **Not reconnecting** or **Not linked**. When connected, it shows the **Number**, what it is **Called**, **Connected since** and **Last spoke to WhatsApp**. With **Not linked**, nothing a client sends is collected. **2. Link a number** Select **Connect a WhatsApp number** and read **Use a number you do not use**: Pragma becomes a linked device on that number, reads and sends its messages automatically, and WhatsApp may ban a number used for automation. Enter **Name this number** (for example `Front desk`, up to 80 characters), tick **I understand this number will be automated and should not be a personal number**, and select **Generate a code**. **3. Scan or type the code** On the phone that holds the number, open WhatsApp → **Settings → Linked devices → Link a device** and scan the code; it refreshes on its own. To pair without the camera, select **Link with a code instead**, enter the **Mobile** being linked, select **Get a code**, then on the phone choose **Link with phone number instead** and type the single-use **Pairing code**. A brief disconnect right after scanning is normal. When **Number linked** appears, check that phone for the confirmation message, then select **Done**. **4. Recover or change the number** If the badge reads **Not reconnecting**, nothing sent to the number is being collected: select **Reconnect**, or **Disconnect** and link another. If a link was started but never finished, use **Show the code** to continue or **Stop trying** to abandon it. **Disconnect** stops collecting bills sent to the number and removes it from that phone's linked devices; nothing already filed changes. Only one number can be linked per firm. ## Bind each client's sending number ![Client Intake tab showing WhatsApp senders and the bind sender control](https://help.pragmachartered.com/images/invoices/client-intake.png) **1. Check who is already bound** Open **Clients → \[client] → Setup → Intake**. Under **WhatsApp senders**, check the list before adding another mobile; **No senders bound** means bills from this client are all being held. The **Intake** tab shows the number of active senders. **2. Bind a sender** In **Their mobile**, enter the client's **10-digit Indian mobile**, for example `9876543210`; the `+91` prefix is shown separately, not typed. Select **Bind sender**; the button stays unavailable for fewer than 10 digits. Repeat for each mobile the client sends from. **3. Understand a Hidden number** A sender may show **Hidden number**: WhatsApp did not disclose that sender's number. It was created when a held message was assigned with its sender remembered, and messages from it still route to this client. Do not type a guessed number to replace it. **4. Unbind a sender** Select **Unbind** beside the sender and confirm **Unbind**. Bills sent from that number stop being filed against this client; nothing already filed moves. The **Email** section on the tab is informational: email intake is not available. On **Settings → WhatsApp intake**, the **Who can send us bills** table lists each active client with its **Senders** count (**None** if nothing is bound) and **Numbers**; select a row to open the client and bind one. A badge such as **2 opted out** lists numbers that replied STOP: their bills still arrive, but they get no acknowledgement back. ## Assign bills from unknown senders When a bill arrives from a number nobody has bound, it appears under **Waiting to be assigned** on **Settings → WhatsApp intake**, with **Received**, **From** (or `unknown`), **File** and **Type**. Nothing is filed until someone decides whose it is. The section is hidden when nothing is waiting. **1. Identify the sender** Check the **From** number and file name with your team or the client before assigning. If the bill is not for your firm, select **Discard**. **2. Assign it to a client** Select **Assign**, choose the client in **File this against**, and leave **Remember this sender for that client** ticked if every future bill from this number belongs to the same client (untick it for a one-off). Select **Assign**, or **Cancel** to back out. The bill is then fetched and read like any other WhatsApp bill and appears in **Review queue**. A received document is not a voucher posted to the client's books (Tally or Zoho Books): [review and approve it](https://help.pragmachartered.com/invoices/review-and-approve.md). The client's **Overview → Messages** tab shows each WhatsApp message and file from that client (see [Request documents from clients](https://help.pragmachartered.com/clients/document-requests.md)). ## When something is refused * **That WhatsApp number is already bound to a client. Unbind it first.** The same active number cannot route to two clients, in your firm or another. Check with the sender and your team before changing a binding. * **Too many attempts. Wait a moment and try again.** Binding attempts are rate-limited. * **A WhatsApp number is already linked. Disconnect it before linking another — one number per practice, or a client would get replies from a number they have never seen.** * **Confirm you understand that this number will be automated before linking it.** * An **Assign** or **Discard** that reports a conflict means a colleague, or the [agent](https://help.pragmachartered.com/automation/agent.md), already handled that message. > [card] Still stuck? > > [Open a case](https://app.pragmachartered.com/support) from **Help & support** in Pragma, or [book a walkthrough](https://help.pragmachartered.com/support/book-a-walkthrough.md) and the team will show you around on a call.
