close.tsKeep the context with one provider and let Flare handle your consolidated books with multi-entity bookkeeping and our network of local compliance partners.
Growth
Flare scales with you from your first set of books to an established finance team.
For pre-seed to Series A teams that need accurate numbers without the complexity. We can setup your general ledger with an appropriate chart of accounts and close the books every month ready for your annual tax filings.
Suggested Scope
For Series A, B, PE backed or later stage companies that have outgrown their accountant. You get the advanced bookkeeping and AP/AR a finance hire would run, without the headcount, plus the detailed reporting your investors ask for.
Suggested Scope
For established finance teams that want more capacity without the hiring headache. US Controllers give you dedicated hours from US-based controllers, for a more integrated role in your existing finance function. Alternatively, Flare Resourcing embeds experienced offshore talent — from associates to managers — so you can also add capacity without the cost of local hiring.

FAQ
How Flare supports startup fundraises.
Before the process starts, if you can. Clean books and a current pack shorten diligence. We also step in mid-process when a data room request list lands and the current accountant cannot keep up.
Seed, Series A, B and beyond. The work changes with the round — a Seed raise needs a tight pack; later rounds need diligence depth and a data room that holds up.
Yes. We have taken multiple Y Combinator companies through their raises and continue to support 2026 processes.
Fundraising support is a scoped engagement around a round. Fractional CFO is an ongoing retainer. Many companies use both — reserved hours that spike when diligence starts.
It is faster if we already close the books. We can still run diligence support after a historic review if you are switching mid-raise.
