How can we help?

Yes, 100%. NexxBalance is built on an offline-first architecture powered by an embedded local SQLite engine. You can create invoices, manage stock, record payments, and print thermal counter slips with zero internet latency (0ms response). Your billing counter never freezes even if your internet goes down for days.

When internet reconnects, it silently syncs encrypted rolling backups to your private Google Drive vault in the background.

Yes, instantly. NexxBalance natively formats bills for standard 80mm (3-inch) POS printers, 58mm (2-inch) mini purja slips, and standard A4/A5 laser/inkjet sheets. It communicates via standard USB, Bluetooth, or Network/LAN drivers without requiring proprietary hardware bundles.

You can customize store headers, add your UPI QR code, print itemized taxes, and include return policy footers directly from the Invoice Studio.

When you finalize an invoice, simply tap "Send on WhatsApp". NexxBalance launches your official WhatsApp or WhatsApp Business application with a pre-filled professional billing summary, payable total, and direct PDF download link.

Because it uses your official WhatsApp client directly, there are zero SMS pack charges, zero third-party gateway commissions, and zero per-message fees.

Never. Your financial data, customer details, supplier margins, and stock costs reside strictly on your local device in an encrypted SQLite database. NexxBalance has a strict, audited zero-data-selling guarantee.

Unlike multi-tenant web SaaS apps that harvest merchant transaction records, you maintain 100% legal ownership and sovereign custody of your business intelligence.

NexxBalance integrates directly with your personal Google Drive account's private appDataFolder. It automatically maintains an encrypted 2-file rolling backup archive (balance_latest.zip and balance_previous.zip).

If your phone or laptop is lost, damaged, or upgraded, simply sign in with your Google account on the new device and tap "Restore". Your entire transaction ledger and product catalog are restored in under 30 seconds.

No hardware requirements. Chanakya AI is engineered with an ultra-lightweight deterministic natural language execution engine and local mathematical optimization heuristics. It runs locally on your existing device CPU in 2 to 5 milliseconds.

It requires zero GPU accelerators, zero cloud LLM subscriptions, and zero external API fees.

NexxBalance automatically computes itemized tax amounts according to official CBIC guidelines. If a single invoice contains items across different tax slabs (e.g. 5% food grain and 18% consumer goods), NexxBalance automatically creates an itemized HSN/SAC summary table.

It clearly splits taxes into CGST + SGST for intra-state sales or IGST for inter-state supply, ready for 1-click GSTR-1 and GSTR-3B monthly reconciliation.

Under GST Rule 138, consignments exceeding ₹50,000 require an active E-Way Bill. NexxBalance automatically detects when an invoice crosses ₹50,000 and calculates the statutory transit validity period (1 day per 200 km for regular vehicles, 1 day per 20 km for Over Dimensional Cargo).

It provides validity expiry warnings so you can apply for an extension within ±8 hours to avoid Section 129 transit seizure penalties.

Yes, seamlessly. You can export your product or customer catalog from Tally, Busy, Vyapar, or any Excel spreadsheet as a .csv file. In NexxBalance, go to Inventory or Customers > Import CSV, map your columns, and all items, opening stock balances, and sale prices are imported in under 5 seconds.

NexxBalance monitors your receivables ledger continuously. Whenever credit payment exceeds customer terms (e.g. 14 days), NexxBalance alerts you with a 1-tap WhatsApp payment reminder containing an auto-generated UPI payment link.

Chanakya AI also calculates a safe credit ceiling for each buyer, warning you if giving additional udhar puts your store at risk of bad debts.

100% Plug-and-Play. Any standard handheld barcode laser scanner gun bought from Flipkart, Amazon, or local shops (Honeywell, TVS-E, Zebra, Pegasus, Inateck, or generic USB/Bluetooth guns) works immediately out of the box with zero drivers or configuration.

Every commercial scanner acts as a standard USB HID Keyboard Wedge. When you pull the trigger, the gun automatically types the barcode digits in under 50 milliseconds followed by an instantaneous Enter key.

In NexxBalance, you don't even have to click on the search bar! NexxBalance's hardware keyboard engine intercepts background laser keystrokes, matches the product barcode or SKU in 0ms from local SQLite, adds the line item, and auto-increments quantity when scanned repeatedly.

No physical barcode gun right now? You can test rapid laser scanning, real scanner audio beeps, and live 80mm thermal receipt printing directly in our Interactive Web Browser Simulator, or use your smartphone camera via our built-in camera barcode scanner!
