Volume tiers
Above 5,000 minutes / month, markup drops to 20%. Above 20,000 minutes, drops to 12%. Published, not negotiated.
What’s NOT included
The line items most agencies bury.
These are real costs you’ll incur on top of our fees. We publish them because finding out about them six weeks into a build is how trust dies.
Meta WhatsApp wholesale message cost
₹0.86 per marketing message · ₹0.13 per utility message · charged directly by Meta to your BSP wallet. We don't mark this up.
DLT registration + voice infrastructure
Telco DLT principal-entity / template registration, SIP trunks, outbound caller-ID provisioning — pass-through at actual cost. We handle the paperwork, you pay the bill.
Third-party SaaS licences
Razorpay transaction fees, premium plugin licences, paid stock photography, domain registration — billed to your accounts directly.
Paid ad spend
If you run Meta / Google / YouTube ads on top of our funnels, the media spend is yours. We can manage the campaigns under a separate retainer.
First measurable result in 21 days or full refund.
We commit to a measurable outcome — leads captured, calls answered, invoices recovered — by Day 21. If we miss it, you get a full refund. Published in our refund policy.
