When you talk about avoiding extra costs in your business then cost cutting techniques and avoiding decisions that can make you lose a lot of money are very important. Other than that you also need to register for trademarks as well. For example, you have come up with a certain mobile app and you have a trademark for mobile app as well, you can avoid a lot of extra costs that way. Imagine using a certain name for your mobile app, only to find out that it is trademarked by someone else after you have made a good reputation for it. You will then be required by law to change it and will have to incur extra cost to rebrand your business. What other ways can you protect yourself from incurring extra costs?
