For small internal tools make sure you understand the business domain. Learn as much as you can about the process you're writing software for. Prioritize error handling over looks.
Set expectations. Small businesses often expect you can do more for less. You're the expert you tell them how long something will take, don't allow them to set the expectation. Breakdown why it will take that sort of time.
Keep all solutions as simple as possible. If you have an internal tool that only one or two administrators use, then chances are you don't need user management. Have one password to secure the app, or make it a desktop app. Maybe you don't need a GUI to report on data, could a monthly report emailed from the system do the same job at half the development time?
The sales team will want reports on everything and can chew lots of time. Chances are management doesn't want this. Try to give data to them in Excel so they can manipulate the data.
