When starting a business, one key decision is whether to sell a product or a service. Each model has its challenges and benefits. Product-based businesses require inventory management, while service businesses depend on expertise and client relationships. Vertical CPA helps entrepreneurs navigate financial strategies for both, from pricing and cash flow to tax deductions. Whether selling digital products, handmade goods, or professional services, having a solid financial foundation ensures long-term success. Understanding expenses, profits, and tax obligations makes running a business easier. Working with an expert accountant helps entrepreneurs make informed financial decisions tailored to their business type.
