Even if it isn't sticky, the organization is sticky. Take time tracking-payroll software, it's pretty simple right? Let people log in, input their time, manager reviews it, some business logic about the different kinds of leave and accrual and all that. Compared to a service like Browserstack, it seems trivial to develop and run. And maybe easier to switch for the customer, right? But to switch you need to... decide a cutover date, make sure the new system supports all your current employee contracts, oh and payroll links to the health insurance as well, and the employee options scheme, and the pension scheme, and you need to input the org hierarchy, but people made tweaks in the old software that won't carry over... not so simple any more.
