Frequently Asked Questions

Can Zilo System operate completely without internet?: Yes. Zilo System is built from the ground up as an offline-first application. All catalog data, inventory levels, customer khata, and invoices are stored locally on your device.
How does the multi-unit conversion work during billing?: You can define conversion factors (e.g., 1 Box = 24 Pieces). When billing, you can sell in boxes or pieces, and Zilo System automatically recalculates the rate, taxes, and stock deductions.
Can we print GST compliant tax invoices and thermal receipts?: Yes. You can switch between 2-inch/3-inch thermal receipts for fast retail and full A4/A5 detailed tax invoices with HSN summaries for B2B wholesale.
How do we migrate from our existing billing software?: Zilo System features a one-click Excel and CSV catalog importer that automatically imports your products, prices, barcodes, and opening balances in seconds.
