There are a few things you can do to simplify your tech repair business.
You can start by keeping your pricing simple. Have a few set repair prices that you charge for common repairs. This way, customers know exactly how much they will be paying upfront.
You can also simplify your business by keeping a small inventory. Only stock the most common parts and tools that you need for repairs. This way, you don't have to waste time searching for parts or tools.
Another way to simplify your business is to streamline your repair process. Have a set process that you follow for every repair. This way, you don't have to waste time trying to figure out what to do next.
Finally, you can use technology to your advantage. There are many software programs that can help you automate parts of your business. For example, you can use a scheduling program to keep track of appointments and a invoicing program to send out bills.
