How to integrate Catalog Items with Telecom Expense Management System and synchronize the devices?

[Joshua Prakash]

I'm in the process of designing a ServiceNow Service Catalog integration for our telecom carrier orders to streamline requests and tighten our Telecom Expense Management (TEM) process.

I've mapped out a strategy and would love to get a "sanity check" from the experts in my network.

My proposed architecture is:

Front-End: A native ServiceNow catalog item (not a punch-out) to provide a seamless user experience. The available device models will be synced nightly from our TEM platform. What is the best process to sync the devices from the TEM platform?

Engine: Flow Designer will orchestrate the entire lifecycle, from dynamic approvals (manager, cost center) to fulfillment and task creation.

Integration: A dedicated, reusable subflow using IntegrationHub will handle the API call to place the order with the carrier/TEM system.

System of Record: The process culminates in the creation or update of a Hardware Asset record in the CMDB. The RITM is the transaction; the CI is the asset.

My question for the ITAM pros: 

What am I missing?

What are the common "gotchas" or hidden complexities in this model, especially around the asset lifecycle (e.g., handling returns, repairs, or swaps)?

I'm particularly interested in how you prefer to manage the device model data (e.g., iPhone 16, 256GB, Blue) that drives the catalog. Is a dedicated custom table the way to go, or do you prefer populating the OOTB Product Model table for better CSDM alignment?

Appreciate any insights or war stories you can share!
