Planning to start an accounting practice is similar to planning a wedding: if you try to do it yourself, you will miss many important details. Here are a few musts to help achieve a (relatively) smooth start: 1. Hire an attorney to handle the legal considerations. 2. Hire a tax expert to help plan start-up expenditures and tax structure. 3. Do your research and compare vendors. This process will develop over time, but I suggest documenting every procedure you undertake to keep the practice running, such as cash reconciliations, running payroll and entering transactions into your ledger. There might come a time when you need someone to help you and this documentation can be a helpful guide. If you want to represent yourself as an accounting firm, your firm needs an active license to practice accounting. The California Board of Accountancy can help with that.
