What are the benefits of outsourced accounting for a small business?

There are many benefits to outsourcing accounting services for small businesses. 

Cost savings is a great benefit for small businesses. Typically hiring outsourced accountants can be more cost-effective than hiring full-time in-house staff, especially when you factor in salaries, benefits, training, and other employment-related expenses, not to mention that businesses can also save on software and infrastructure costs.

Outsourced accounting firms specialize in their field, ensuring that businesses have access to experts with the latest knowledge of accounting principles, regulations, and tax laws. Ideally you’ll work with an outsourced accountant who is also an expert in your industry, like we are at Plumb. This can lead to higher quality work and fewer mistakes.

As a business grows, its accounting needs can change. Outsourced accounting services can be scaled up or down as required, allowing for flexibility without the commitment of hiring or laying off staff.

By entrusting accounting tasks to professionals, business owners and their teams can focus on core business activities, such as product development, sales, and customer service.

By outsourcing accounting needs, small businesses can tap into the expertise of top financial professionals and gain access to advanced tools and resources, all without the cost of maintaining an in-house accounting department.

How does an outsourced accountant help with things like inventory management and sales tax compliance?

An outsourced accountant can assist with inventory management by analyzing inventory costs and turnover rates; implementing and managing accounting systems that track inventory movement, costs, and valuation; and making year-end adjustments for inventory shrinkage, obsolescence, or other inventory-related matters. They can also provide important monthly, quarterly, and annual inventory reports to help with business planning.

When it comes to Sales Tax Compliance, an outsourced accountant can help with determining the appropriate sales tax rates for products in different jurisdictions. They can also prepare and file sales tax returns and ensure timely payment of collected taxes. If under audit, an outsourced accountant can provide all essential documentation. Additionally, an outsourced accountant will remain up-to-date on any changes to sales tax laws and will keep you informed about any new requirements. 

By outsourcing these responsibilities with an experienced ecommerce outsourced accounting team like Plumb, businesses can ensure accuracy, compliance, and focus on their core operations.
