An honest comparison

Filing in April is the last step, not the system.

FlyFin points AI and CPAs at your return — deductions found, filing handled. Post runs the business underneath it: real double-entry books, creator income tracked at the source, and a set-aside answer that's current in July, not just April.

Built around your income

What “built for creators” actually means.

01

Creators aren't generic freelancers

Freelancer tools model invoices and clients. Creator income is platform payouts on their own schedules, brand wires that don't match the contract, affiliate commissions, and PR that counts as income at fair market value. Post models exactly that, natively.

02

Books underneath, not just a return on top

Post keeps real double-entry books — P&L, balance sheet, trial balance, general ledger. That's what a lender, a CPA, or an S-corp conversation eventually demands, and a filing service doesn't produce it.

03

The year-round number

"What should I set aside this month" needs an answer in July, not just at filing time. Post's engine — federal, self-employment, your state — recalculates continuously from the ledger as money lands, reviewed by a team of accountants.

04

Your CPA works in the books

Invite your accountant as a collaborator — their own accounting-language view, comments, adjusting entries, free seat on Pro. A working relationship all year instead of a March data dump.

Estimates, not tax advice — your write-offs and credits shift every line. Self-employment tax is usually the surprise: it’s often bigger than income tax.

The IRS’s cut of that

≈ $1,762/mo isn’t yours.

Federal $7,581 + self-employment $13,564 a year — an effective 22% before state tax.

Common questions

Does Post prepare and file my return like FlyFin does?

No — and that's a real difference. Post keeps the books, runs the year-round tax math, and produces tax-software-ready exports; the actual filing happens in your filing software or with your CPA, who gets a free collaborator seat on Pro.

FlyFin includes CPAs. What does Post include?

Post's tax engine is reviewed by a team of accountants, and your own CPA can work directly in your books with a free Pro seat — their own accounting-language view, comments, and adjusting entries. Post doesn't prepare returns; it makes whoever does faster and more accurate.

I already have a CPA who files for me. Which tool fits?

That's Post's home game: it keeps clean creator books all year and hands your CPA real financials — P&L, trial balance, general ledger — instead of a shoebox. Filing services replace your CPA; Post equips them.

Can I use Post together with a filing service?

Yes. Post's exports hand clean, categorized numbers to any preparer — human, software, or service. The books are yours; where you file from them is your call.
