Integrations with ticketing&#x2F;CRM systems.  You can hit the high notes, and go for the handful of most common ones, but it&#x27;s always a temptation to chase a deal and promise another one.  Pretty soon, you&#x27;re spending all your time chasing down things in a half-dozen or more systems, that all have their own idiosyncratic SDKs or APIs, which change at unpredictable rates.  Moreover, to do development and testing against those systems, you&#x27;ve got to keep those environments up, and seeded with test data.  Some of them are cloud-based, and you can get a free&#x2F;low cost development instance, but others are big, unwieldy on-premise deployments that require a host of servers to run all their gunk - with costs in server racks, provisioning time, setup time, and non-core expertise in keeping that crap going.
