The Sunday-night tax.

There is a tax that doesn’t appear on any state form. Our state sales-tax guides won’t catch it. It’s the one small operators pay the last Sunday of every month — kitchen table, laptop open, two browser tabs and a spreadsheet that refuses to balance.

One tab holds the processor statement. The other holds the bank feed. The spreadsheet in the middle is the place where the two are supposed to agree, and the rule of the night is the one you already know: they don’t.

A $40 refund from three weeks ago is on one tab and not the other. A chargeback lands on the processor side a day before the bank does. A tip line shows up in the POS export and nowhere else. The Sunday-night operator moves them by hand, line by line, until the spreadsheet balances — until the books say what the bank and the till already agreed on hours ago, just not in the same row, just not in the same column.

That tax — the one nobody bills you for, the one you pay in hours and in sleep — is the one we built Stillpost to retire. Same bank feed. Same processor. Same POS. The loop runs nightly, not on Sunday. The spreadsheet is the output, not the work. The Pennsylvania sales-tax explainer walks the Allegheny-and-Philadelphia local-rate layer that sits on top of the state base.

The books your CPA opens on Monday are the books you slept through. That is the beat. That is the loop. That is what gets handed back.
