Consider carefully how you will spend your money. How much will you reinvest into your business? Will you order business cards? Invest in a tablecloth? A banner? Add a little inventory? Maybe purchase some stamps so that you have them on-hand for mailing thank you cards and reminder postcards? Maybe you'll get paper and ink for your printer? Keep you receipts; these are business expenses and can be counted in next year's taxes
Will you pay for some marketing or advertising? A listing on a website, a blog sponsorship, an ad in the local highschool yearbook... Replenish your business supplies, catalogs, brochures, samples, postcards...
