Accounting & ERP Guides, Comparisons, and Tools for Growing Businesses

Still trying to figure out whether QuickBooks, Xero, Zoho, or a full ERP system is the right fit; or whether your current setup just needs to be cleaned up and configured properly? This is where Certum Solutions publishes the guides, comparisons, checklists, and case studies we wish more businesses had before they signed a software contract or hired a bookkeeper. Everything here is written by our own accounting and ERP consulting team for U.S.-based small and mid-sized businesses (roughly $1M–$50M in revenue) evaluating their systems in 2026; not outside contributors guessing at what matters.

Is it a Hobby or a Business? Use Your Common Sense

Is it possible to turn your hobby into a business? Possibly, but there are some definitive IRS rules you need to be aware of—and income you need to report on your tax return. Hobbies are near and dear to us. They help us get through stressful times and reflect our passions.
