Frequently Asked Questions
How does billing work after my free trial?
After your 7-day free trial, your account is locked until you pick a plan. You can choose from Starter (₹199/mo), Pro (₹499/mo), Business (₹999/mo) to continue. Yearly plans come with a 20% discount.
Can I manage multiple businesses from one login?
Yes. You can add multiple businesses under a single account and switch between them in one tap. Each business has its own separate data, invoices, and inventory.
How do I share invoices on WhatsApp?
After creating a bill, tap the 'Share' or 'WhatsApp' button on the invoice page. This opens WhatsApp with the invoice pre-attached as a PDF or image. The customer's saved number is pre-filled if you've added it to their profile.
Is there a mobile app?
Zentra is a Progressive Web App (PWA). On Android, open the website in Chrome and tap 'Add to Home Screen'. On iOS, open in Safari and tap 'Share → Add to Home Screen'. It installs like a native app and works offline.
Can I export my data?
Yes. You can export your customer list, invoices, and inventory data as CSV files from the Settings page. This works on all plans.
How do I add my GSTIN to invoices?
Go to Settings → Business Profile and enter your GSTIN in the designated field. It will automatically appear on all future invoices.
What payment modes can I record?
You can record payments made via UPI, cash, card, bank transfer, cheque, or credit (dues). Zentra tracks outstanding balances automatically.
Troubleshooting
Common issues and quick fixes.
Page not loading or spinning
Try a hard refresh (Ctrl+Shift+R on desktop, or clear cache from your browser settings). If the issue persists, try opening Zentra in a new browser tab or in incognito mode.
Invoice not generating
Make sure all required fields are filled — at least one line item and a customer name. Check that your GSTIN format is correct in Settings if you're using GST mode.
WhatsApp share not opening
Ensure WhatsApp is installed on your device. On desktop, make sure WhatsApp Web is set up. Try saving the PDF first using the Download button and sharing manually.
Can't log in — wrong password
Use the 'Forgot password?' link on the login page. A reset link will be sent to your registered email address. Check your spam folder if it doesn't arrive within 5 minutes.
Data not syncing between devices
Zentra syncs automatically when online. If you're seeing stale data, try refreshing the page. Make sure both devices have an active internet connection.
