You don't need fancy offices to be successful. In fact just the opposite. Successful small businesses do well precisely because they keep a tight rein on costs and don't let them spiral out of control by spending them on frippery they don't actually need.
However, the office needs to be of a reasonable standard. Firstly to keep your staff happy. If they don't have good furniture and a pleasant environment to work in, then their happiness and productivity will suffer. Secondly, clients and prospective customers will want to come and visit your premises from time to time and first impressions count. If they see a shoddy office with poor quality furniture, they will be non too impressed by what they see.
Take a look at your current meeting room. Does it look like the sort of place that a customer would want to sign a new contract in? Maybe it's need something of a spruce up and some new meeting furniture. Don't assume that you have to break the bank to get some new meeting tables and chairs to improve the look and feel. You find great deals online, both on new and reconditioned furniture.
Such a small outlay on new meeting furniture can really pay dividends. If customers are overlooking you because they aren't sure about you because of the state of the office, then it won't take much to fix this issue. Once you have your new meeting tables and other bits and pieces you can really dazzle them with a corporate environment that tells them business is good and you and your company are on the up. Neglect it and they might remain unsure as to whether you are a good prospect to do business with. If you can't even kit out a nice place to do business, then what can they expect further down the line?
