You build the business.
We handle everything behind it.
TSW Core is a CPA-led platform that takes on the background admin: company formation, governing documents, bookkeeping, payroll, business taxes, IRS and state notices, and your individual return. You stay focused on customers, product, and growth.

Founders shouldn't be part-time accountants.
Entity choice, operating agreements, payroll filings, quarterly estimates, a letter from the IRS. The admin side of a company piles up fast, and it usually lands on the founder. TSW Core takes it off your plate and keeps it in one place, under one CPA-led team.
One partner, from formation to tax day
Company formation
Pick the right entity (LLC, C-Corp, or S-Corp) and get set up properly from the start.
Bylaws & operating agreements
Help drafting your governing documents during setup.*
Bookkeeping
Clean monthly books and reports you can actually use.
Payroll
Employee pay, payroll taxes, and filings, handled.
Business taxes
Planning and preparation for federal and state business returns.
IRS & state notices
Got a letter? We review it, explain it, and help you respond.
*Drafting assistance only. TSW Core is a CPA firm, not a law firm, and does not provide legal advice.
Two ways to work with us. We only win when you win.
Some founders want a predictable bill. Others would rather conserve cash and bring us in as a partner who's invested in the outcome. Both are equally valid choices, and either way you get the same team and the same standard of work.
Fixed Fee
A clear scope at an agreed fee. You always know what you're paying for.
For founders who: want to keep 100% ownership · are already profitable, where a profit share would cost more over time · plan to raise and want a clean cap table, predictable costs, and simplicity
Equity Partnership
Instead of a traditional fee, TSW Core takes a small stake in your company and receives monthly distributions. Each partnership is negotiated individually.
Equity partners: We run your back office (formation, bank accounts, books, and taxes) so you can focus on your product.
For founders who: are early-stage and cash-constrained · would trade some upside for full back-office support now · want a partner invested in their growth
