In Kommo, the product catalog is a centralized space for storing the products and services your business offers. Linking products to leads helps your team keep purchase details connected to each sale. It helps you:
Track purchase history — all purchased items are stored directly in the lead profile.
Calculate sale values — add purchased products and their quantities, and Kommo will calculate the totals automatically.
Get detailed reports — Kommo uses sales data to generate analytics and reports.
This article shows how to link products to leads, view totals and purchase history, and access your reports.

To link products to a lead:
Go to Pipelines, open the pipeline you need, and click the lead to open it.
Click Products.
Click + Add.
Search for a product or scroll through the list and select the product.
The product will be added to the lead profile, and the note will appear in the activity field.
To change the quantity, click x1 (default), then enter the number of items purchased.
The total sale value will be calculated automatically, and the product will be saved to the lead.
