My team has been building custom software for a large german multinational shipping and freight forwarding company for 18 years now. Happy to chat, my email is in my username @ gmail.

Our client has tried what you're discussing several times. They are a bit bigger (10x) than your org, but never built up the software muscle in house despite hiring and firing entire teams to attempt to build stuff in house. We've handled one corner of their offerings for nearly 2 decades while all their other teams have cycled in and out of internal and external suppliers.
