What should i put in my resume about budgeting?

I am applying for this job and the only budgeting experience i have is sorting income from expense and mainting a certain budget on what products to purchase under a given amount of money. Is there a term for these two specific things i do that i can put in my resume instead of rambling on word by word of what i can do?

maybe you should include activities such as forecasting and making a cost savings plan
