This is going to be an increasing trend. 
Does anyone have a read on whether this was custom built, bought in, or a mix?
For example, there are several companies that can supply an multi-order in store cart picking solution (employee picks for 6-8 part orders at a time), although early entrants like Tesco–and hence Safeway Groceryworks–developed their own.
I doubt it was custom-built personally. As you said it’s a competitive space. Heinen’s is not a huge chain. Most people (outside of the majors) should not be building their own software platform.
