WhatsApp order updates spare your team the same delivery questions again and again, but only when they follow Meta's rules. Here is how to choose between the Business app and the Business Platform, collect opt-in, get templates approved and trigger each message from your ERP.
Key takeaways
A customer who can see where their order is does not need to call and ask. That is the case for WhatsApp order updates: a short message when the order is confirmed, another when it leaves the warehouse and a last one when it arrives, on the app the customer already uses to talk to you.
Doing it well takes more than a phone and a broadcast list. Meta, which runs WhatsApp, sets rules on consent, templates and timing, and updates that ignore them get rejected, charged as marketing or reported. This guide covers those rules, the ERP events that should send each message, handover and measurement.
WhatsApp offers businesses two products, and only one of them can send updates automatically.
The WhatsApp Business app is a free app for small businesses. It runs on a phone, plus a few linked devices, and adds a business profile, a catalog, quick replies, labels and greeting and away messages to ordinary chat. It has no interface your ERP can call, and its broadcast lists only reach contacts who have saved your number, so every update is typed or forwarded by hand.
The WhatsApp Business Platform is built for businesses that message customers from their own systems. Software connects through an API (application programming interface), usually Meta's Cloud API, which Meta hosts and where new features arrive. You can connect directly or through a solution provider that supplies the inbox, the integrations or both.
| Question | WhatsApp Business app | WhatsApp Business Platform |
|---|---|---|
| Best for | Owner-run businesses chatting from a phone | Businesses sending messages from an ERP, online store or helpdesk |
| Connects to your ERP | No | Yes, through the Cloud API or a provider |
| Messages you start | Manual chats and broadcast lists | Approved message templates, sent automatically |
| Cost | Free app | Meta charges for conversations you start with templates |
Order updates, delivery notices and payment reminders all need the Platform. If you run Odoo Enterprise, its WhatsApp app connects to a Platform account and sends approved templates from records and automated actions; our Odoo Enterprise team sets it up.
Meta's rule is that you may only message people on WhatsApp who have given you their mobile number and agreed to receive messages from your business. Since Meta's November 2024 policy update, that permission can be general rather than specific to WhatsApp, as long as it meets local law. Its opt-in guidance asks that the wording a customer agrees to makes two things clear:
Opt-in can be collected on your website or checkout, by SMS, through a phone menu, on paper or in person. What matters for automation is where the answer is kept. Record it on the customer in your ERP, with the date, the source, the phone number and the kind of messages it covers, and let every automated send check it.
Keep order updates and offers apart. Meta suggests either one opt-in that lists the kinds of message a customer will receive or a separate opt-in for each kind. A customer who agreed to delivery notices has not agreed to promotions.
Opting out must be just as easy. Tell customers how to stop, for example by replying STOP, and honor it everywhere, not only on WhatsApp. People can also block or report a business, and sustained low quality can limit how many customers you are allowed to message.
Tip: Write the opt-in sentence so a customer could repeat it back, for example: "Send updates about my orders from [your company name] on WhatsApp." Use a box the customer ticks, not one ticked for them, and never bury consent in your terms and conditions.
Every message your business starts, as opposed to a reply, must use a template that Meta has approved. A template has a body plus an optional header, such as an image or a PDF invoice, a footer and buttons. Variables such as {{1}} and {{2}} are filled with the customer's name, the order number or a date when the message is sent. Each language version is reviewed on its own, so Arabic and English dispatch notices are two approvals.
Meta sorts templates into three categories, and the category decides how a message is treated and charged:
An order update stays utility only while it stays about the order; add a discount code or a product suggestion and it becomes marketing. Since 9 April 2025, if you submit a template as utility and Meta decides it is marketing, Meta approves it as marketing, and it can also change the category of approved templates later. Meta's template category guidelines give examples of each.
Meta reviews each template you submit, with automated checks and manual review, and a decision can take up to 24 hours. A rejected template can be edited and resubmitted, or the decision appealed. The usual causes are badly formed variables, such as mismatched braces, numbers out of sequence or a variable at the very start or end, content that breaks WhatsApp's policies and duplicates of templates you already have.
Approved templates also earn a quality rating from customer feedback, and one that keeps drawing blocks can be paused.
When a customer messages you, a 24-hour customer service window opens, and every new message from them starts it again. Inside the window you can reply freely with text, images, documents and buttons. Once it closes, the only thing you can send is an approved template.
For order updates this has two consequences. Anything your ERP sends on its own schedule, such as a dispatch notice or a payment reminder, must be a template. And a customer who replies to an update opens a window, so whoever answers can share a proof of delivery, a payment link or a new slot without another approval.
The window also shapes cost. Conversations you start with templates are charged by category and by the customer's country, while service conversations, where you answer a customer, have been free since 1 November 2024. Meta has announced that from 1 July 2025 it will charge per delivered template message instead of per conversation, so check Meta's pricing page before you plan volumes.
A good update answers the question a customer would otherwise phone about, at the moment the answer changes. In an ERP that moment is an event, so tie each message to one event and build it from data the system already holds.
| ERP event | What the update says | Useful button |
|---|---|---|
| Sales order confirmed | Order number, a short summary and the expected delivery date | View order |
| Delivery dispatched | Driver or courier, delivery window and tracking link | Track delivery |
| Delivery date changed or stock short | The new date, or what ships now and what follows | Talk to us |
| Delivery confirmed | A delivered notice, with a way to report damage or a missing item | Report a problem |
| Invoice posted | Invoice number, amount and due date, with the PDF attached | Pay now |
| Due date approaching | A polite reminder with the amount and a payment link | Pay now |
All of these stay utility messages while they carry no promotion. A few rules keep them useful:
Here is how one order might flow for a distributor selling to retailers:
Replies to order updates are often questions only a person can settle: a different delivery time, a damaged carton, an invoice that does not match the order. WhatsApp's business policy allows automated replies inside the customer service window, but it also requires prompt, clear and direct escalation paths, such as transfer to a human agent, a phone number or email.

No. The WhatsApp Business app is designed for one-to-one chats from a phone and has no interface that an ERP or online store can use, and its broadcast lists only reach contacts who have saved your number. Automatic order updates need the WhatsApp Business Platform, connected through Meta's Cloud API or a solution provider, with message templates approved by Meta.
Yes. Meta only allows businesses to message people who have given their mobile number and agreed to receive messages from that business. The permission does not have to mention WhatsApp, but it must make clear that the person is agreeing to messages from your business, it must name the business and it must meet local law. Store the consent in your ERP and check it before every automated send.
Order confirmations, shipping and delivery updates and payment reminders are utility messages when they are about a specific order and contain nothing promotional. Adding an offer, a discount code or product recommendations turns them into marketing. Since 9 April 2025, if Meta decides that a template submitted as utility is really marketing, it approves the template as marketing.
It is the 24 hours after a customer's last message to your business. During that time you can reply with free-form messages, including text, images, documents and buttons, without a template. Once the window closes, you can only send approved message templates, so notifications your system sends on its own schedule should always use templates.
Meta reviews each template you submit, with automated checks and manual review, and an approval decision can take up to 24 hours. If a template is rejected, you can edit it and submit it again, or appeal the decision. Common causes of rejection are badly formed variables, content that breaks WhatsApp's policies and duplicates of templates you already have.
