Manual — from our website
No coding. Log in and:
- send an SMS / voice call / email campaign to one number or a whole list,
- fill an invoice form — customer, products, amounts — and press Send,
- paste many rows (name, phone, date, amount) and send everyone their own receipt or statement,
- type today's payments per customer and send the daily report with one click,
- write an offer and send it to all customers or only VIPs, now or at 9 AM tomorrow.
Automatic — from your software
Connect your shop, POS, ERP, school or ISP software once with an API key:
- an order is completed → customer gets a thank-you + points SMS instantly,
- every sale / payment is pushed to us → the customer gets a report every night,
- a subscription renews → an invoice goes out every month until the end date,
- a sale starts or new stock arrives → your whole list gets the offer,
- we call your webhook after every send so your system knows what happened.
