samriswinpaul123/smart-accounts ? reverse-engineered prompt

Build me a web app for small business accounting with invoices and double entry bookkeeping.

I want users to be able to sign up, log in, add customers, create and send invoices, record payments, and keep track of income and expenses in a clean ledger style view. The app should make sure every transaction is balanced, so debits and credits stay in sync automatically. I also want a dashboard that shows account balances, recent activity, outstanding invoices, and simple totals at a glance.

Please make it feel modern and easy to use, with a straightforward frontend and a solid backend that saves data properly. Add the basic pages and flows a real user would need, like creating accounts, viewing transactions, and managing invoice status from draft to paid. If you need to check any current best practices or docs while building it, go ahead and look them up online.
