How and What to Consider with your Budget:
Have a Budget:This may sound so obvious, but if you have no finances to work with you will need to find some, it may be actual dollars and cents, or it maybe a good or service you have than will translate into your start up budget. Whatever it is make sure you have something to budget. A little goes a long way, but nothing can't get you out of the starting gate, some ventures may just need a dime to get going but plan a way to get that dime.
Keep a budget a side for marketing, marketing can be one of the most expensive parts of starting new venture. Getting the word out about your business doesn't have to take up your whole budget but allotting a portion of your budget to get the word out about your business is going to be one of the major factors of your success.
Be Real:Putting down, or counting on imaginary start up funds that you haven't yet acquired, will not work in your favor, that is like digging yourself a hole before you've even begun. Having a tiny budget to start off with is nothing to be ashamed of, it may actually be more motivation to work harder, but you have to be sure you REALLY know how much you have to work with.
Acquiring Additional Funds:When you decide that you will make the leap to acquire additional funds, be it through liquidating your current goods, taking out a loan from a financial institution or from a friend or family member BE SURE that the hole you have put yourself in, is the step you needed to get your revenue to grow. Really look at your situation if you are trying to get more funds that will set you back with no clear way of recovering, it may be a good time to cut your losses and take a different direction.
Interests RatesSo you've decided to take that loan, but before you sign on the dotted line, know what it all means, don't allow yourself to sign a contract that is just jargon (words you have not idea about). It may seem like you've already done so much just deciding to get the loan, where to get it and how to get approved that more work is out of the question. Signing a loan contract without know what it's about is like jumping into a pool of sharks, it will financially and possibly mentally tear you a part. Think of it this way, it is highly likely you will have to deal with financial institutions and their terminology again, so why not get familiar with it now, you'll be way more comfortable in the long run and you'll have a lot less worry along the way.

Return on Investment (ROI):When you've placed or are planing to place your money towards inventory or an action plan to bring in more revenue, you always have to consider the return of investment. Practically consider that what you are investing in is worth your time and money. There are some advice on how to  Maximize your return of investment.
