Cerillion and Comverse cutovers for European operators
Promon migrates and runs both stacks — billing, catalog, CRM, orders, and charging. Delivery from Chennai. Scoping in your morning. Night cover on the bill run. We stay through go-live.

24/7 ops on the bill run
Why a European operator hires us
We are not a London brass plate. Chennai is the delivery centre. The work is on the BSS you already named in the RFP.
Cerillion and Comverse — both, not one
Catalogs, accounts, bill cycles, and charging. We cut over and run Cerillion and Comverse: coexistence, parallel runs, a rollback the team would use. TM Forum when that is the estate.
Billing transformationYour night is our morning
A Sev-1 at 02:00 CET is a ticket with an owner in Chennai, not a voicemail. Live programmes get 24/7 cover. Scoping stays in 08:00–12:00 CET so your billing lead is on the call.
Managed operationsSame engineers through hypercare
The people who map the catalog stay for the first bill run. No workshop team that vanishes. Private AI, when you want it, stays on your network — no subscriber data to a public model.
Work we will put a name toTimezones, stated
Overlap when it matters. Cover when it breaks.
IST is ahead of CET. That is the point for overnight operations, not a problem to hide. Sales and design sit in your morning. Production sits through your night.

Work we will put a name to
We do not invent European client logos. We show the programmes: Cerillion and Comverse cutovers, and the operations that stay up.
BSS migration
Catalogs, accounts, and billing cycles onto Cerillion with rehearsed coexistence — not a weekend gamble.
ComverseCharging, One, and OCS
Comverse One and online charging cutovers — recharges, prepaid events, and the first cycle rehearsed before it is live.
GDPR: inquiries stay in our CMS so we can reply. Subscriber data from your network never lands on this website. Privacy
