Kappal Platform Stack
PropelOS
The operating system for digital revenue.
PropelOS is a modular commerce and operations platform for businesses whose revenue depends on moving goods, orders and inventory across channels. Run B2B and B2C on one system, prove new sales models in a sandbox, and modernize around the legacy systems you already run.
Built for operations
Enterprise revenue operations without the rewrite
Storefront tools are cheap. Core ERP replacements are months long and risky. PropelOS sits between them: modular, proven and deployable without touching the systems that keep you running today.
Modernize without the rip out
PropelOS runs as a modern commerce and operations layer on top of your existing ERP and legacy systems. You modernize the front of the business first, and replace the back only when it makes sense.
One system for B2B and B2C
Procurement teams get catalogs, quotes and approval flows. Retail teams get storefronts and checkout. Both read from the same inventory, pricing and orders, so no channel is ever out of sync.
Validate before you commit
We spin up a live proof of concept on our infrastructure in days, with your catalog and pricing, before your core ERP is involved. You see real sales flow before you approve a wider rollout.
Enterprise-grade by default
SOC 2 certified infrastructure on GCP and Azure, DPDP aligned and GDPR ready data handling, NDA and data processing agreements by default, and a 99.9% uptime commitment.
