you can link multiple vendor contracts to a single contract.
That means you can bill all services for a single customer using a single contract in the PSA and a single invoice at the end of the month.
For example, you manage both Google and Microsoft products for one customer. You can now sync both tenants into a single contract.
Goolash will list all linked contracts when you examine a single contract. That way you can't forget which ones are related.
It's not possible to combine contracts of the same application yet; they have to all be of a different vendor.
