The best time to hire an accountant or accounting service is when these tasks start to take up too much of your time and you lose focus on building out our product, hiring, finding customers etc. You should also outsource this if you’ve raised >$1M of outside funding.

You should expect to receive you GAAP based financials on a monthly basis and high-quality customer service. Simplexity is always available via phone and/or email.


“This is the service I recommend the most highly out of all the services that we use because they save me the most time on finances and HR. They’re a human system, not a software system. My team at Simplexity has become an extension of our team and has an in-depth knowledge of the business not commonly found with an outsourced resource.”

Russ Heddleston

“If you want to grow your company by leaps and bounds that’s when you need to look at Simplexity. They’ve helped us turn our books and financials into venture ready financials. And helped us focus on the business and not be distracted with HR and all the end of the month responsibilities.”

Avi Tal, Co-Founder of Agentology

“They’re very forward thinking. There’s not a month that goes by where there is something that I need to be aware of that I wasn’t thinking about. If Simplexity wasn’t handling all these different services, there’s no way I could focus on what’s critical for the company.”
