How We Support Your Growth
Finance and Accounting for Start Ups
When you’re building a company, finance can often take a back seat, until it starts slowing you down. SumnerCo helps bring order to the chaos, putting structure and clarity behind your numbers so you can focus on growth. We’ve seen what happens when finance gets pushed aside in the early days - messy books, missed filings, and painful (and often more expensive) audits later on. Putting the right systems in place early saves time, reduces stress, and sets your business up to scale smoothly.
How SumnerCo supports early-stage organizations:
Guiding companies through their first audit
Building revenue recognition and balance sheet reconciliation processes
Designing sales commission structures
Establishing a month-end close that delivers timely, accurate results

Whether it’s getting through the first audit, preparing for growth, or simply bringing order to financial operations, SumnerCo helps start-ups move from ad hoc to organized
