WhatsApp Business API for home services businesses: setup, rules and real costs

The app is fine until these start happening to a home services business:

• Booking by phone is slow and often missed. Customer calls for AC service at 1 PM. You're on another job. Missed call. They call a competitor. WhatsApp bookings never miss.
• Customer doesn't know when technician arrives. "I waited 3 hours and nobody came" — because you didn't send an ETA. A simple WhatsApp saves the job and the customer.
• Calls go unanswered while technicians are on site. Your team is under a sink or on a ladder. The phone rings, nobody picks up, and that job goes to whoever answers first.

The app cannot send on a trigger, share one number across staff, or read your records. The API can. And customers keep asking the same things: customers ask whether a technician can come today, what a visit costs, when the technician will arrive, and whether the work has a warranty.

• A verified Meta Business account in the home services business's legal name, backed by a registration, GST or utility document.
• A number not active on the WhatsApp app — your current one works once it is removed from the app.
• A display name matching the business, and a website or public page Meta can check.
• Opt-in from every customer you message first. The booking — customers want the technician's arrival time and details anyway.

1. Connect the number through Meta's embedded signup inside Reputoo, and submit business verification — you can start sending within Meta's starting limit while it is reviewed.
2. Get your first templates approved for the 4 routine messages listed below; anything outside a customer's 24-hour reply window must be a template.
3. Wire the triggers to your records. What to connect: A job-scheduling tool or dispatcher sheet with technicians and slots.
4. Put staff on one shared inbox, with conversations assigned so two people never answer the same customer.

A business doing 600 jobs a month with about five utility messages each sends around 3,000 — roughly ₹345 in Meta fees on the July 1, 2026 India rate card. A pre-summer AC servicing campaign to 2,000 opted-in customers costs ₹1,726 at ₹0.8631 per message.

Letting a stranger into your home is the moment of doubt in every home-services booking. Sending the technician's name, photo and arrival window on the morning of the visit, and a message when they set off, turns an unknown person into someone the customer expects. Many customers — especially elderly people and those at home alone — will not open the door otherwise.

Meta charges per delivered template message, and the price depends on the category. For home services businesses, the day-to-day messages sort like this:

• Service booking via WhatsApp in 60 seconds — utility
• Technician dispatch notification with ETA — utility
• Job completion + next service reminder — utility
• Annual maintenance reminder sent automatically — utility

Timing matters as much as category. Booking confirmation straight away, technician details and arrival updates on the day, and service-due reminders for periodic work.

A service reply answers a customer who wrote first; from 1 October 2026 Meta charges those at the utility rate. Utility messages (confirmations, reminders, status updates) cost a fraction of marketing messages, so keep them strictly transactional — a discount line inside a reminder makes Meta classify the whole template as marketing.

Meta list rates, July 1, 2026. India in INR, plus 18% GST.

For anything beyond the standard visit — a part to replace, extra units, a deep-cleaning add-on — send the quote in writing before the work starts and ask the customer to approve it with a button. Disputes about the final bill almost always come from work that was agreed verbally at the door.

After each job, send a short service report — what was done, parts replaced, anything the customer should watch for — with the invoice and the warranty terms. When the AC stops cooling again next month, both sides can see exactly what was done and whether it is covered.

Meta rates every number on how customers react. For home services businesses, the risk is usually messaging the whole contact list about something only some of them asked for. Send reminders only to people with a booking or order, promotions only to people who opted in to them, and never use a bulk-sender tool on the ordinary app — that is the route to a banned number. The full list of what Meta checks is in our WhatsApp Business API guide.

A window of two hours is only useful if it holds. When a technician is running late, a message with the new time — sent before the window starts, not after it ends — keeps the customer from taking leave for nothing. Dispatchers can send it from the shared inbox in seconds.

A payment link sent with the invoice lets the customer pay by UPI or card while the technician packs up, and the receipt arrives on WhatsApp. Technicians do not carry cash, and the business sees every payment against the job.

For cleaning, painting and repair jobs, before-and-after photos sent with the service report show the work done. Ask customers before photographing inside their home, and never use those photos in marketing without separate permission.

A dispatcher on one phone, technicians messaging customers from their own numbers, and no record of what was promised — that is how most home-services businesses start. The API puts every customer on the business number, lets dispatchers work from a shared inbox, and keeps the history with the business when technicians change.

When technicians message customers from personal phones, customers start calling them directly for the next job — and the business loses the customer. Keeping communication on the business number protects both the customer relationship and the technician, who is not called at midnight.

An AMC for ACs, water purifiers or pest control includes a set number of visits a year. Send each visit's reminder with a button to pick a slot, a note of visits remaining, and a renewal reminder a month before the contract ends. Customers who never have to remember their AMC renew it.

1. Week 1: move to the API; approve booking, technician, job-done and service-due templates.
2. Week 2: send technician details and on-the-way messages for every job.
3. Week 3: service reports, invoices and payment links after each job.
4. Week 4: service-due reminders for periodic work.

Whether jobs live in a scheduling app or a dispatcher's sheet, messages should be triggered by the job's status — booked, assigned, on the way, done — so no one has to remember to send them and every customer gets the same experience.

A burst pipe or a power failure cannot wait for tomorrow's slot. If you offer emergency visits, say so clearly, state the emergency charge before dispatching, and send the technician's details as soon as someone is assigned.

When a customer reports that a problem has returned, acknowledge it in the same thread as the original job, check the warranty from the service report, and book a re-visit. A quick, fair response to a complaint is the strongest reason customers stay.

Tell customers how your technicians are verified, that they carry identification, and whom to contact if anything feels wrong during a visit. A line in the booking confirmation is enough, and it reassures the people most worried about letting someone in.

Residential societies, offices and landlords book repeat and bulk work, and the person who books is rarely the person at the door. Send the booking confirmation to the contact who booked and, with their agreement, the technician details to the person on site — a facility manager, a tenant, a security desk. One thread per property keeps the history of every visit together, which matters when a society asks what was done in which flat.

A day after the job, ask the customer to rate the visit with a single tap. Low ratings go straight to the manager to call the customer; high ratings can receive your review link. Ratings per technician also show who needs training and who deserves recognition.

When a part has to be ordered, tell the customer the expected date in writing and send an update when it arrives, with slots for the follow-up visit. A job that stalls silently while a part is on order is one of the most common reasons for complaints.
