Income, as it actually arrives
Every sale posts its own ledger line. An invoice nobody paid never counts.
The threshold is $400.
The trigger is $433.14.
fuime totals what you collected and what you spent, and says how far the difference is from the IRS threshold.
Start your business
It is an estimate. fuime files nothing.
The arithmetic
Four hundred dollars, after the multiplier.
The $400 test runs on profit times 92.35%.

Flagged
What it tracks
Income, expenses, net profit, all year.
Four numbers, kept current by the ledger itself rather than typed in at the end of the year.
Expenses, with the receipt attached
What you spend sits beside what you earned, fuime's own fee included.
Net profit, updated as you go
Recomputed whenever the ledger moves, and the page says what still reaches $433.14.
A packet somebody else can read
A CSV stamped as an estimate, for a guardian to download and hand on.
What counts
Income is what arrived, not what you billed.
Overstating what somebody owes is the more harmful mistake, so the doubtful cases fall out.
An unpaid invoice
It stays outstanding and never counts toward the threshold.
Your own money in
Money you put into the business is excluded, on a best-effort basis.
A refund
Income falls, and fuime's fee is rebated in proportion.
Where it stops
Six things this does not do.
Other platforms say they handle tax. fuime does not handle tax.
It does not file anything
No return, no extension, no quarterly payment.
It does not calculate sales tax
No sales tax, no VAT, no GST, and zero registrations.
It does not touch checkout
Read off the ledger after the money has moved.
It is an estimate, not a determination
Income is classified by heuristic, and no accountant has signed off.
It only knows what it can see
A cash job, a W-2 shift, another platform: none of it lands here.
It is not tax advice
fuime is not a preparer and not an advisor.
Start
Keep the books while the year is on.
Reconstructing twelve months in April is the expensive way to find out what you owe.
