How it works

Live on your number in one day. We do the setup with you.

01

Connect your WhatsApp number

Your existing business number, or a new one. Customers see your business name, not ours.

~20 minutes
02

Fastrill learns your business

Your services, prices, timings, staff, languages. You review its answers before it goes live — nothing reaches customers without your sign-off.

Same day
03

Customers book while you work

Fastrill answers, books, collects payment and reminds. You watch everything from one dashboard and jump into any chat whenever you want.

From day 1

What it handles

A full-time receptionist's job. Minus the salary, leaves and lunch breaks.

Bookings — the core

Books, reschedules and cancels real appointments

Fastrill checks your actual calendar, offers open slots, confirms the booking and blocks the time. Reschedules and cancellations handled in chat too — with reminders before every appointment so no-shows drop.

Languages

Speaks your customer's language

Telugu, Hindi, English and 7 more — including the Hinglish mix people actually type. Auto-detected per conversation.

"It replied to a patient at midnight and I woke up to a booked slot with advance paid."— the moment it clicks for every owner
Campaigns

Bulk WhatsApp campaigns

Send festival offers to your entire customer list. Fastrill handles the flood of replies and converts them into bookings — with full revenue tracking.

Lead recovery

Wins back lost leads automatically

Customer went quiet after enquiring? Fastrill follows up over 24–48 hours and brings them back — without you lifting a finger.

Payments

Collects advance payment in chat

UPI payment links sent inside WhatsApp. Advance-paid customers actually show up. No-shows drop dramatically.

Missed calls

Recovers missed calls instantly

Can't pick up? The caller instantly gets a WhatsApp message from Fastrill and books there instead.

Analytics

Revenue per campaign & booking trends

See which campaigns drove bookings, which services are trending, peak hours, and customer lifetime value.

Control

You stay in control, always

Complex question or upset customer? Fastrill alerts you and steps aside. Take over any chat, any time.

Results

Real businesses. Real numbers.

I was losing Saturday night bookings because nobody replied after 8 PM. Customers now book at midnight and wake up to a confirmation. It paid for itself in the first week.

Questions owners actually ask

Before you ask —

It replies as your business, in your tone, with your real prices and timings. Most customers just notice they finally got an instant answer. You can jump into any conversation yourself whenever you want.

It only answers from the business information you approve during setup — it doesn't invent prices or promises. Anything it's unsure about, it politely takes the customer's details and alerts you to follow up.

You answer questions about your business — services, prices, timings. We handle everything technical and you're live the same day. If you can use WhatsApp, you can use Fastrill.

Yes — we connect your number to WhatsApp Business API (your chats and contacts stay intact), or you can run Fastrill on a fresh number. Your choice.

If it booked appointments for you, you'll want to keep it — pick a plan from your dashboard, cancel anytime. No lock-in, no awkward calls.

Hindi, Telugu, Tamil, Kannada, Malayalam, Marathi, Bengali, Gujarati, Punjabi and English — auto-detected per conversation. No configuration needed.

Don't take our word for it.
Take Fastrill's.
