FAQs About Bookkeeping Services in New Jersey
What's the difference between bookkeeping and accounting services?
Bookkeeping focuses on recording daily financial transactions, maintaining accurate records, and organizing your financial data. Accounting services leverage that data to prepare tax returns, provide strategic advice, and help with important decisions. Think of bookkeeping as the foundation and accounting as the analysis. At Demian & Company, we provide both services and can help with whatever your business needs.
How often should I have bookkeeping done for my small business?
Typically, most small businesses benefit from monthly bookkeeping services, though some companies with high transaction volumes need weekly attention. Monthly financial reporting gives you regular insights into your business performance and keeps you organized for tax season. We'll assess your business and recommend a schedule that aligns with your volume and particular needs.
Can you help if my books are behind or disorganized?
Absolutely. We specialize in cleanup projects for businesses that have fallen behind or have disorganized records. Our team can catch up on your books, organize past transactions, and set up systems that prevent future problems. Many of our clients came to us with months of backlogged work, and we helped them get current and stay that way.
Do you work with my existing accountant or tax preparer?
Yes, that’s no problem. We work closely with accountants and tax preparers throughout New Jersey. Our accurate financial records make their work easier and more efficient during tax season. If you already have an accountant you trust, we'll coordinate with them to ensure everyone has the needed information.
What bookkeeping software do you use?
We specialize in QuickBooks, which is the most popular choice for small and medium-sized businesses. However, we also have experience with Xero, FreshBooks, and other platforms. If you're already using specific software, we can work with it. If you're starting fresh, we'll help you choose the best option for your business and industry.
Can I outsource all my bookkeeping to your team?
Yes. In fact, many of our clients use us as their complete outsourced bookkeeping department. We handle everything from daily transaction entry to monthly reports, saving you the cost and hassle of hiring in-house bookkeepers. This approach gives you professional service without the overhead of full-time employees.
How quickly can you get started with my bookkeeping?
Usually, we can start within a week of our initial meeting. The timeline depends on how much historical work needs to be done and how quickly you can provide access to your accounts and records. For businesses with current books, we can often begin immediately.
