Konnash

Konnash is a free digital cash book and ledger app for small merchants and service businesses that need to record customer and supplier transactions, track debts, and follow up on payments from a phone.

Key capabilities include:

• Debt and balance tracking: record credit/debit transactions in seconds, view balances per customer or supplier, and see when debts are settled.
• Payment follow-up: send payment reminders to customers (SMS or WhatsApp) to speed up collection.
• Sales and expense logging: track daily sales (cash or card) and record expenses such as rent, stock, and transport to keep visibility on day-to-day finances.
• Business wallet and payments: keep personal and business money separate with a built-in wallet, collect payments using a link or QR, and pay suppliers to bank accounts or mobile wallets (with the option to add a note or invoice photo).

Available on Android and Web.

It targets individual merchants including retailers, wholesalers and distributors, repair and service providers, and craftsmen who want a paper-free way to manage customer debts and business cash.
