Questions people ask before they start

Something else on your mind? Write to support@regenterp.com or message us on WhatsApp.

Do I need to install anything?

No. RegentOne runs in any modern browser on Windows, Mac, Android or iPhone. Sign up, add your company details and you can raise your first invoice in a few minutes.

How does e-invoicing work?

RegentOne connects to the GST portal through an authorised GST Suvidha Provider. You add your e-invoice API username and password once, and every eligible invoice gets its IRN and signed QR code with one click. E-way bills can be generated from the same screen.

Can I bring my data from Tally?

Yes. Import your parties, items and opening balances from Tally or from Excel files, and export vouchers back to Tally whenever your auditor needs them.

What happens when the trial ends?

Choose a plan and pay online by UPI, card or net banking. Everything you entered during the trial stays as it is. Nothing renews automatically: you pay for each month or year when you choose to.

Will I get a GST invoice for my subscription?

Yes. A GST tax invoice is issued for every payment, so you can claim input tax credit.

Can I manage more than one company?

Yes. Each company has its own books and its own subscription, and you can switch between them from the same login.

Where can I get help?

The Help Center inside the app walks through every screen. For anything else, email or WhatsApp us and our team will reply on working days.

Raise your first GST invoice in the next ten minutes.
