A delivery report is the product
Anyone can accept a message. The difference is whether you can prove what happened to it afterwards, and whether the person who sold it to you will pick up when it fails.
About
A communications company you could drive to
Belsync has been building messaging, telephony and commerce systems from New Delhi since 2024. We started by reselling SMS, got tired of explaining other people's outages, and built the stack ourselves.

How we work
Four things we will not trade away
We will tell you not to buy something
If Shopify fits better than a custom build, or your current SMS vendor is already priced well, we will say so. Losing a sale is cheaper than losing a reference.
The engineer who built it supports it
Handing a finished system to a stranger in a support queue is where most projects quietly rot. Our builders stay on the account.
Local means reachable
Our office is in Nangloi and our team is on Indian time. You can escalate to a name, not a ticket number in another time zone.
