For LLCs or corporations, a DBA or FBN (fictitious business name) will let you operate multiple businesses without having to form a separate LLC or corporation for each business. Let’s say your business wants to expand into multiple websites, stores, restaurants, services, etc. You can create a corporation with a relatively generic name and use a DBA for each individual business. This will cut down on your paperwork and expenses when you’re operating multiple projects.
It’s the easiest way to register your name: If you’re a sole proprietor, then filing for a DBA or FBN (fictitious business name) is going to be the simplest and least expensive way to use a business name. You can create a separate professional business identity, without having to form an LLC or corporation. And for sole proprietors, a DBA or FBN (fictitious business name) is required in order to open a bank account and receive payments in the name of your business.
Keeps your business compliant: If your business is an LLC or corporation, you enjoy certain legal protections. However, these protections may be invalidated if you’re operating under a different name and didn’t file for a DBA or FBN (fictitious business name). For example, I may have incorporated Summer Flowers Gardening, Inc. But if I sign a client contract under Summer Flowers (or some other variation like that), that contract may not hold up in court.
