Your outsourced tax department built for SaaS.
Tax leadership for $10M–$500M SaaS companies—an alternative to your first full-time hire
At $10M+, Tax Gets Risky Fast
What worked early on doesn’t hold up once you’re scaling, expanding, or acquiring.
This is built for you if:
You’re expanding into new countries
You’ve made (or are considering) an acquisition
Sales tax notices are starting to show up
You are starting to pay taxes and need to forecast cash tax 12-36 months out
Your accounting team hates working with tax issues. You want to alleviate this duty form them so they can focus on the financials
You have multiple advisors, but no one is leading the tax function
Your CPA firm is filing returns, but planning feels reactive
Your board or investors are asking deeper tax questions
You’re considering hiring a full-time tax person but don't know if you could keep them busy "full-time"
We become your tax department
We lead the tax function day-to-day, coordinate across internal teams and external advisors, and make sure your tax strategy is designed to reduce your tax burden as your business scales.
