- R&D Tax Claim

FAQ
Frequently asked questions
How Flare's fractional CFO support works.
The service
You get reserved hours from senior Flare team members who have done the work — fundraising, M&A, forecasting — not a rotating junior bench. Your bookkeeping account manager stays in place alongside them.
Board packs, cash forecasting, investor reporting, fundraising support and M&A work. We agree a monthly hour block and the priorities inside it.
Bookkeeping is the close. Fractional CFO time is judgement on top — what the numbers mean, what to tell the board, and how to prepare for a raise or a deal.
Working with Flare
It is strongly preferred. CFO work is faster and more accurate when it sits on a close we already own.
Some companies use fractional support until they are ready to hire. Others keep it as the senior layer while Flare Resourcing embeds day-to-day talent. We can help you decide which is which.
