Why I built this.

I'm Ying. I founded ET Management — an accounting firm in Singapore. For thirty years I watched the same thing happen, again and again.

A baker who whipped up the most beautiful cakes but couldn't tell you if she made money this month. A consultant brilliant at strategy who hadn't filed a return in two years because she didn't know where to start. A trader who knew his margins to the dollar — but had a shoebox of receipts behind the till.

They were too small for a real accountant. Too confused for Xero. Too proud to admit they were drowning.

Last year I stepped back from the day-to-day at my firm. For the first time in a long career, I had the time — and the savings — to build something I'd been meaning to build for years. AI had finally matured enough to do the boring 80% of the work reliably. So I poured both into Yi.zy.

If you outgrow it, my firm and a small handful of partners I trust are around. But mostly I want you to use it free, for as long as you need to. Your data stays yours. There are no upsells. I made sure.
