Perform a financial analysis. Identify how much money comes in and from which sources, and how much money is spend, and on which budget lines (think of costs involved with facility maintenance, equipment purchasing and maintenance, supplies, human resources, etc.). This enables you to prepare for the costs for the next year. If you see that the costs are going to be higher next year (for example because a new piece of equipment needs to be purchased, or because new staff must be hired), you can already anticipate this by starting to look for more funding.
