Full stack financial operations for startups

We help startups manage their accounting and finance functions with unprecedented ease. Don’t fret over bookkeeping, billing, budgets or board reports — just leave it all to us.

Bookkeeping

Clean financial statements & reports hit your inbox each month. They are prepared on a accrual basis and reviewed by your dedicated OpStart controller. You can ask questions or request changes at any time – our team is here to help.

Taxes

For one flat price, our tax team will handle all your essential filings throughout the year: income taxes, 1099s, Delaware franchise taxes, K-1s, and more. If you qualify for R&D tax credits, we’ll take care of that too so you maximize savings. It’s a pain-free experience for founders: just sign-up in January and let our experts do the rest.

Fractional CFO

Stay on top of your metrics, goals, and momentum with strategic support from our fractional CFOs. We produce custom KPI dashboards, operating models, forecasts, and more so your management team and board members stay focused on the right targets. If you need to raise capital, we’ll help you shape your metrics into a powerful narrative and create a deck + data room that will impress investors.

Billing & Invoicing

Never worry about paying another bill or sending an invoice – We take care of all your bills, customer contracts, and invoicing, and track incoming and outgoing payments. Forward bills directly to our team and we’ll set them up for payment (with your approval, of course). Share your customer contracts with us and we’ll create all necessary invoices (while ensuring revenue is recognized appropriately). It’s a truly hands-free experience for making and collecting payments.

Payroll Setup & Compliance

Payroll software makes it easy to cut checks and withhold taxes automatically, but we think founders deserve more support. Our experts are on-call throughout the year to help you respond to notices, register in new states/jurisdictions, make system adjustments, and more. Turn off those system notifications and stop fretting over the mail you receive from state agencies – we’ve got it covered.

Back Office Setup

Focus on scaling your startup – not setting up back-office software. Our team will construct a software stack that scales with your business, allowing you to operate efficiently from day one.

We integrate with all your favorite systems

Trusted by the best

We Integrate With All Systems

OpStart powers financial operations for startups across the country,
ranging from pre-seed to Series C.

Bring your own back-office software stack, or let our experts set it up for you. We won’t mandate any system transitions but are happy to make recommendations and assist with setup. We also have preferred discounts with many of the most popular systems on the market, so sign-up with us before you begin paying full price.

Don’t take it from us – listen to our customers

With our experience, credibility, and expertise, you can rest assured your financial operations are in capable hands.
