The problem

Running an Amazon business takes too many tools — and you still don't know your real profit.

A generic business checking account. A2X to translate your Amazon settlements into QuickBooks — and QuickBooks itself, bloated general-ledger software built for accountants, not sellers. You pay for two subscriptions and a bank that weren't built for this, and you still can't get a straight answer on whether you made money.

✓Every settlement, broken down automatically
✓Automatic tax set-aside
✓Export-ready P&L and tax packages

Why it's different

Bookkeeping, fully automated.
QuickBooks and A2X, gone.

QuickBooks hands you software to operate and a ledger to maintain. Stonaris does the bookkeeping for you and asks you to confirm only what it isn't sure about — the more you confirm, the more it learns, until there's almost nothing left to do.

Why we built Stonaris

“I was paying for two subscriptions — A2X just to translate my Amazon settlements into QuickBooks — and QuickBooks is bloated accounting software built for accountants, not Amazon sellers. After all of it, I still couldn't get a straight answer on what I actually made.”

I didn't want a chart of accounts and journal entries. I wanted to see what each payout contained and whether I was profitable — from a bank built for my business, not a generic checking account. Stonaris is that: banking and books in one place, Amazon data understood natively, and a profit number I can actually trust.
