Ritchalison/BalanceDesk ? reverse-engineered prompt

Build me a local first Windows app for small business daily reconciliation called BalanceDesk.

It should let a user record sales, credit sales, credit payments, and cash or MoMo expenses, then review one business day at a time and close the day with physical cash and MoMo counts. I want it to calculate the expected totals, variances, overage or shortage, and keep a clear audit trail for corrections, cancellations, reopenings, and allocation reversals. Please include standard user and administrator flows, customer credit accounts, invoices, payment allocation, duplicate checking, backup and restore, and a simple setup process that keeps everything inside the app folder using SQLite and a local only server on the computer. It should not rely on cloud login or remote services, and it should stay private on the local machine.

Make it feel like a real desktop app that opens in a browser window on Windows. If you need to, look up current docs online for any Windows or browser setup details.
