- Process mismatch / impedance : The software is unlikely to be able to do exactly what you want how you want. The human likely is able
- Vendor lock in: If the SaaS decides to change how it works, or the prices you now have a leaving cost
- Expenditure on someone else's competitive advantage: If you use tool X likely there is no reason your competitor cannot. You both use it, no net advantage gained over competitor. If you develop the expertise in house (likely the harder thing) then you have an advantage over your competitor. Of course this has to be balanced with what will be your competitive advantage and what will not
- Harder to manipulate: You cannot fire 1 of your SaaS and tell the other 2 to do the work
