Good points.
With some notable exceptions B2B vendors (I was a large VAR at one point) have generally been mired by their large investments in outdated solutions.
Their customers haven't been waiting for them.
One client who has seen a 30% increase in revenue during the past year with ZERO increase in cost, attributes much of the revenue growth and all of the cost efficiencies to some simple browser-based mobile apps we developed over the past couple of years. Their accounting software is a VFP based package that I installed in 2001. Unless someone changes the double entry bookeeping rules, it will probably stay around for 15 more years.

The operating back office is, and will probably remain indefinitely, desktop C#/SQL Server.

Another client is on the same path.

Our clients' customers are more demanding than ever.
At least once a month, one of their customers demands that paper billing be replaced by some kind of electronic transmission- usually with some quirk.
The back office has to be readily adaptable.
C#/SQL Server is perfect in that regard.
