SHI - delayed paymenets?

A fair number of corporate customers use SHI as a reseller to purchase my products.

They are normally a good prompt payer - but recently (last 3 months) they have been very late.

Anyone else seeing this?

I try to make them pay in advance. They usually do. Afterall the customer has already told them to get the software, so they aren’t in a great bargaining position.
