Senzing subscription pricing is based on DSRs. A DSR is a single record processed to load into Senzing (searches are not counted).
Another option is to get a Senzing Unlimited license which provides unlimited DSRs and unlimited free support. This may cost no more than the support contract on your existing MDM or entity resolution software.
If you want to learn more about DSRs and pricing, see Data Source Records (DSRs) Explained.
