Does it have to be one or the other? Can you contract the work to an agency, in effect leasing developers without having to bring them in house? I worry that without a culture to sustain and nurture a software team over time, whatever you build this year will become nightmarish tech debt a few years later. Dev turnover might be high due to limited advancement potential / lack of resume building opportunities / not enough sexy problems to work on. Institutional memory between generations of devs might be hard to maintain and your totally custom software might get harder and harder to work on and use as the years to by. It doesn't seem like a great way to run an essential part of your business. Can you switch to a more responsive vendor but then find an agency to do the day to day dev work and add custom code as needed? I've spent much of my career working in tech roles for non tech companies, and I've seen a lot of bespoke custom garbage that's really hard to work on. It ends up being more forensic than engineering work, with a lot more reverse engineering and landmine avoidance than new feature development or UI improvements. I try to steer these types of businesses into commercial off the shelf software whenever possible, but maybe building custom webhooks and such into them. It's a lot easier to have a solid base built and maintained by a good vendor, with some small snippets of modular code (webhooks, plugins, extensions, etc.) added on top. No one feature is tied into everything else, so less experienced devs can fix or replace it modularly without having to reverse engineer your entire custom stack.
