Simplicity is a feature until it is a ceiling
Doorr is quick to start and uncomplicated, and that is a real virtue. A tool people actually use beats a platform nobody populates, and plenty of brokerages have made themselves miserable buying more software than their operation justified.
The question is where the ceiling sits. Lightweight workflow tools tend to handle the deal in front of you well and offer progressively less as the questions become about the book behind it — retention, compliance evidence, commission structures across agents.
If you are not asking those questions yet, this comparison is not urgent for you. If you are, the gap is structural rather than a matter of configuration.
