Hi littleriver, I ran a small software business for a few years before starting on this great path of bodywork, I could say lots of things, but first off, do you have/know an accountant? They know all about this stuff, and can save you a lot of time, and remove any risk of getting it wrong. Someone specialising in small business accounts would be good. Also, your bank may be a good source of information, even if you are not ready to open a business account with them. By the way, it is a really good idea to start thinking of your business as a separate person from yourself - get a separate bank account for your business, if it doesn't have one of its own yet, to keep everything separate from your personal finances. Lend your business a little money to get it started, if you need to, and then, whenever the business buys something, the money comes out of the business's account, and whenever you do a treatment, the money goes into the business account. Keep a piece of paper (the printed receipt/invoice) recording each thing your business buys, and file them in the order of the date received. Keep another piece of paper (or a record in a spreadsheet) everytime your business takes any money in, and again store them by date. That way, you have a full record of all the incomings and outgoings, and once a month, it's a no-brainer to check them against the bank statement and tick them off, and spot any mistakes in the paperwork (doing the bank reconciliation). You will always have a clear picture of where your business is, how profitable it is, and how much it can afford to pay you as wages. Of course, your business has to pay its taxes before it pays your wages :-( and it should also keep some money of its own each month - this can be used for buying things, or expanding, in the future, and also, eventually you and your business may even decide that it can pay you back the initial loan ;-)Not sure of any relevant books or websites, as I'm in England and things may differ a little, but these basics are pretty standard.
