For a small team handling a few straightforward WhatsApp conversations, linked devices in the WhatsApp Business app may be enough. For managed queues that need assignments, clear ownership, handoffs, or reporting, consider a shared inbox connected to the WhatsApp Business Platform. The right choice depends on how many people need access and how much control the team needs—not simply whether several people can open the same number.
Before moving an existing business number, confirm how the provider handles number eligibility, app migration or coexistence, and chat history. These details differ by provider and can affect customer-facing service.

WhatsApp Business app or Platform-connected team inbox?
These are different ways to share access to a business number. The WhatsApp Business app can be used with linked devices. A team inbox typically connects through the WhatsApp Business Platform, also called the WhatsApp Business API. Do not assume that an integration built for the Platform also works with the mobile app or supports using both setups on the same number.

For example, Intercom documents support for the WhatsApp Business Platform/API, not the WhatsApp mobile app versions. Its instructions also say an existing app account on the number must be deleted for its integration, with associated history and account data at risk of loss. That is specific to Intercom; other providers may have different migration or coexistence procedures. Intercom’s WhatsApp connection guide

When linked devices may be sufficient
If a small group mainly answers incoming messages and does not need formal ownership, routing, or supervisor reporting, begin by checking the linked-device capacity and features on the account. WhatsApp’s Help Center says a WhatsApp Business account can use up to four linked devices at once without keeping the primary phone connected. The primary phone must log in at least once every 14 days to keep linked devices connected. WhatsApp Help Center: link a device with QR code
The Help Center also says Meta Verified can allow up to 10 devices and chat assignment to agents. This is subscription-dependent; confirm that Meta Verified and the feature are available for the account and location before relying on them.
When a team inbox is worth considering
A shared inbox can add workflow controls that device linking alone may not provide: assignment and reassignment, internal notes, tags, permissions, shared history, collision indicators, department queues, integrations, and reporting. These are features to evaluate rather than guarantees that every provider or plan includes them. WhatsTeam, for example, advertises a set of multi-agent inbox features on its product page; those are vendor claims, not independently tested results. WhatsTeam product page

Features to compare before choosing an inbox
Compare the operational setup and the specific plan, not just the provider’s headline subscription price. Limits, billing, and available integrations can differ between products and tiers.
| Area | What to check | Why it matters |
|---|---|---|
| Capacity | Concurrent linked-device and agent limits, number limits, and plan caps. | A cap can require a change in workflow as the team grows. |
| Assignment and ownership | Manual claim, round-robin or other routing, reassignment, and what happens when an agent leaves. | Clear ownership helps prevent unanswered or double-handled conversations. |
| Coordination | Typing or collision indicators, internal notes, shared history, and handoffs. | Agents need context and a way to avoid sending conflicting replies. |
| Access control | Role-based permissions, private assignments, departments, and audit trail. | Different roles and queues may require different access. |
| Visibility | Response-time and workload reporting, searchable conversations, and plan restrictions. | Managers need to understand queue health and how each metric is defined. |
| Integrations and data movement | CRM or help-desk connections, automation, exports, and API access. | These determine whether agents can work in connected systems and move records when needed. |
| Migration | Number eligibility, coexistence, history retention, downtime, and rollback. | Moving a live customer-facing number can affect service and historical records. |
| Total cost | Seats, inbox subscription, messaging charges, onboarding, support, and any additional Meta charges. | The subscription alone may not represent the full operating cost. |
| Messaging workflow | Template approval and controls for customer contact under current WhatsApp rules. | Outbound initiation has policy requirements that need to fit the team’s process. |
How to set up a WhatsApp team inbox safely
Exact onboarding steps vary by provider. Treat the following as a decision and preparation sequence; follow the selected provider’s current instructions for its product and region.
- Choose the connection type. Decide whether the team will stay in the WhatsApp Business app with linked devices or connect the number to a Platform-powered inbox. Ask the provider directly whether its route supports app use with the same number. Intercom’s documented integration is for the Platform/API, not the mobile app.
- Confirm number and account prerequisites before changing anything. Check business-account administrator access, verification requirements, consistent business details and display name, access to the phone number for verification, and any provider-specific regional or currency requirements. Intercom’s guide, for instance, describes a USD WhatsApp Business Account currency requirement for its integration; this should not be assumed to apply to other providers.
- Resolve migration and history questions before onboarding. If the number is already active in the Business app, ask the provider whether the number is eligible, whether migration or coexistence is supported, what history is retained, whether downtime is expected, and whether rollback is possible. If the process requires deleting the app account, first preserve information the team needs. Intercom warns that its deletion step can permanently remove associated chat history and account data.
- Complete the provider’s verification and connection steps. Use the provider’s live setup instructions, since eligibility and interim limits can vary. Intercom says its verification can take upwards of 48 hours and describes limited sending and number allowances while verification is pending; those details apply to its documented process.
- Prepare templates for business-initiated messages. Meta says businesses using the WhatsApp Business Platform can initiate messages only with pre-approved templates. Plan time for template submission and approval, and build current customer-contact rules into the workflow. Meta: Ways To Manage Your Businesses Chats On WhatsApp
- Run a controlled test before public rollout. Use the provider’s test method, such as a QR code or message link where available, or verified test numbers. Check inbound routing, ownership, notifications, saved replies or templates, reporting, and an agent handoff with a small internal group. Intercom documents a test link/QR flow for its product.
- Assign ongoing account responsibilities. Decide who controls administrator access, billing, templates, number recovery, agent offboarding, and provider escalation. Record the owners so service does not depend on one person’s account access.
How to choose for your team
A few agents handling simple inbound conversations
Start by checking whether the account’s linked-device capacity covers the people who need access. Pair devices using WhatsApp’s official linked-device flow rather than sharing account credentials informally. If agents begin stepping on one another’s replies or the team needs accountable ownership and reporting, reassess whether the app setup still fits.

Frequently Asked Questions
How many people can use one WhatsApp Business number?
WhatsApp’s Help Center says a WhatsApp Business account can use up to four linked devices at once. It says Meta Verified may allow up to 10 devices and chat assignment to agents; availability depends on the subscription and account or location. A Platform-connected team inbox has its own provider and plan limits.

It depends on the provider’s supported connection path. Do not assume the app and Platform inbox can share a number unchanged. Intercom’s documented integration supports the WhatsApp Business Platform/API, not the mobile app versions, and its guide requires deleting an existing app account on the number.
Will moving my number to a team inbox keep my chat history?
History treatment depends on the provider’s migration procedure. Intercom warns that deleting the existing app account for its setup can permanently lose associated chat history and account data. Check the chosen provider’s current instructions and preserve needed records before making a change.
Can a business start a WhatsApp conversation with a customer?
Meta says businesses using the WhatsApp Business Platform can initiate messages only with pre-approved templates. Check Meta’s current rules and plan for template approval before building outbound workflows.
