Yes, through the WhatsApp Business API. A school ERP sends attendance alerts, fee reminders, exam results and announcements to parents on WhatsApp, and the parent receives them from a verified business number rather than a teacher's personal phone.
The rules are stricter than most schools expect, and the cost is not zero. Both are worth understanding before a vendor demo, because the limits come from Meta rather than from the ERP, and no vendor can remove them.
Business API versus a teacher's personal WhatsApp
Most Indian schools start with class groups run from teachers' personal numbers. It works until it does not.
| Personal WhatsApp / groups | WhatsApp Business API | |
|---|---|---|
| Sender | A teacher's own number | The school's verified number |
| Record | Lives on that teacher's phone | Logged against the student |
| Leaving staff | Takes the history with them | Nothing is lost |
| Parent replies | Go to the teacher, any hour | Route to the office |
| Sending to 800 parents | Manual, or a broadcast list capped at 256 | Supported |
| Cost | Free | Per conversation, see below |
| Parent sees | A personal number | School name and verified tick |
The practical trigger for schools is usually a dispute. A parent says they were never told about a fee deadline, and the only record is in a WhatsApp group a teacher has since left. The API version puts that message against the student record with a delivery timestamp.
What a school can and cannot send
This is where most expectations need adjusting. WhatsApp divides messages into two kinds.
Template messages are pre-approved formats you can send at any time. Every proactive school message is one of these: absence alerts, fee reminders, exam schedules, result notifications, holiday announcements, transport delays. The text is fixed, with variable slots for the student name, amount, date and so on.
Session messages are free-form and can only be sent inside a 24-hour window that opens when the parent messages you first. If a parent asks a question at 10am, your office can reply freely until 10am the next day. After that, only a template.
What this means in practice:
- You cannot send an arbitrary ad-hoc message to a parent who has not contacted you recently. It has to be a template.
- You can reply freely to a parent who just asked something.
- You cannot use WhatsApp for marketing to people who have not opted in. Admission promotion to a purchased contact list is a policy violation and risks the number.
- You can message parents of enrolled students about school matters, since that is an existing business relationship, provided they have not opted out.
Opt-out must be honoured. A parent who replies STOP must stop receiving messages, and the ERP should record that rather than requiring someone to remember.
How template approval works
Each template is submitted to Meta and reviewed, usually within 24 to 48 hours, though it can be longer during busy periods. Approval is per template, not per message.
A template looks like this:
Dear
{{1}}, your ward{{2}}of class{{3}}was marked absent today,{{4}}. Please contact the school office on{{5}}if this is incorrect.
The fixed text is approved once; the variables are filled per send.
What gets rejected, in rough order of frequency:
- Promotional language in a template submitted under a utility category
- Spelling and grammar errors, which are treated as a quality signal
- Variables at the very start or end of the message, or two adjacent variables
- Vague content where the reviewer cannot tell what the message is for
- Anything resembling a loan, lottery or prize offer
Practical consequences for a school: build your templates before admission season, not during it. A fee reminder template rejected on 1 April is a week of manual calling. Most schools need somewhere between eight and twenty templates to cover a year, and regional language versions are separate templates requiring separate approval.
What actually costs money
WhatsApp Business API is billed by Meta per conversation, not per message, and the rate is set by Meta rather than by your ERP vendor. A conversation is a 24-hour window, so several messages to the same parent inside one day usually bill once.
Meta prices conversations by category, and the categories matter to schools:
- Utility conversations cover transactional messages: fee receipts, attendance alerts, exam schedules. This is most school traffic and is the cheaper band.
- Service conversations are parent-initiated. These are free in current Meta pricing.
- Marketing conversations cover promotion, including admission campaigns, and are the most expensive band.
- Authentication covers OTPs.
Because Meta sets these rates and revises them periodically, no vendor can honestly offer unlimited WhatsApp. Treat an unlimited claim as a reason to ask exactly what happens at ten times your expected volume.
Rates change, so check current Indian conversation pricing on Meta's own documentation rather than relying on a figure in any vendor's slide, including ours.
What to establish with a vendor before signing:
- The included monthly conversation allowance, as a number
- The overage rate, and whether it is billed at Meta's cost or marked up
- Who owns the WhatsApp Business account, the school or the vendor
- What happens to the number and templates if you leave
Point three matters more than it sounds. If the vendor owns the business account, your verified number and approved templates do not travel with you.
Setup: what a school has to do
Setup is mostly paperwork and usually takes one to two weeks.
- A phone number not currently registered to any WhatsApp account. A new SIM is cleanest. A number already on personal WhatsApp must be deleted from it first, which erases that history.
- Facebook Business Manager verification for the school, requiring registration documents and proof of address. This is the step that takes longest.
- Display name approval, which must plausibly match the verified business name.
- Template submission, 24 to 48 hours per batch.
- Parent number data cleaning, which schools consistently underestimate. Numbers must be in international format and belong to the parent rather than the student. Expect to find duplicates, landlines and disconnected numbers.
Start the verification step early. Templates can be drafted while it is pending.
FAQs
Does school ERP software work with WhatsApp?
Yes, through the WhatsApp Business API. The ERP sends attendance alerts, fee reminders, exam results and announcements from the school's verified number, with each message logged against the student record. The rules on what can be sent come from Meta, not the ERP, so they apply to every vendor equally.
What can a school not send on WhatsApp?
A school cannot send a free-form message to a parent who has not contacted it in the last 24 hours; that requires a pre-approved template. It cannot send marketing to people who have not opted in, including admission promotion to purchased lists, and it must honour opt-outs.
How long does WhatsApp template approval take?
Usually 24 to 48 hours per template, though it can run longer in busy periods. Approval is per template, and each regional language version counts separately. Build your templates before admission season rather than during it.
Do WhatsApp messages to parents cost money?
Yes. Meta bills per 24-hour conversation rather than per message, with utility conversations such as fee reminders and attendance alerts in a cheaper band than marketing. Parent-initiated service conversations are currently free. Because Meta sets these rates, no vendor can genuinely offer unlimited WhatsApp.
Can we use our existing school WhatsApp number?
Only if it is removed from regular WhatsApp first, which deletes that account's history. Most schools register a new number instead and keep the old one running during the changeover.
Who owns the WhatsApp Business account, the school or the vendor?
It should be the school. Ask explicitly, because if the vendor owns it, your verified number and approved templates stay with them when you leave. This is one of the more expensive things to discover late.
