Frequently Asked Questions

Common questions about this comparison answered.

Vendors estimate effort, add buffer for risk, and price accordingly. Good vendors are accurate; the buffer covers unknowns. If scope changes, change orders adjust the price.

Changes are handled via change orders – documented scope additions with pricing. Good contracts define the change process clearly. Some flexibility is usually built in.

It can be if the vendor lacks integrity. Choose partners you trust, set clear expectations, and maintain visibility. The benefit is genuine flexibility for evolving requirements.
