Contact supportIs BillZ really free?
Yes. The Free plan stays free: 25 invoices a month, one business, GST invoices with UPI QR, PDF export and basic reports. You don’t need a card to sign up, and you upgrade only when you need more.
Are BillZ invoices GST compliant?
BillZ invoices carry the details GST rules ask for: your and your buyer’s GSTIN, invoice number and date, HSN/SAC codes, taxable value, place of supply and the CGST + SGST or IGST split. E-invoicing (IRN) and e-way bills are on our roadmap. If your turnover requires e-invoicing today, talk to us first.
How does the AI invoice feature work?
Type a sentence like “Bill Ravi Hardware 20 TMT 12mm at 720”, or upload a photo or PDF of a bill. BillZ fills in the customer, items, quantities, rates and tax. You check it and press save; nothing is saved without you. AI features are included from the Starter plan.
Is my business data safe?
Your data travels over HTTPS and is encrypted at rest on Google Cloud (Firebase) and Neon’s managed Postgres. Staff logins have roles, every change is logged, and we never sell your data. Our Privacy Policy lists every service provider we use.
Can my staff and accountant use BillZ?
Yes. Invite people with Admin, Accountant, Staff or Viewer roles. Free includes 1 staff login, Starter 2, Business 5 and Pro unlimited.
How do I pay, and can I cancel?
Pay securely with UPI, cards or net banking through Razorpay. Paid plans renew automatically and you’ll be notified before each renewal. Cancel any time from Settings → Subscription or your UPI/bank app; you keep access until the end of the period you paid for.
Do you give refunds?
Yes, as set out in our Refund & Cancellation Policy. If you’re not happy within the first [7] days of your first paid purchase, write to us and we’ll refund you in full to your original payment method within [5–7] working days.
Can I bring my data from Excel or another app?
Yes. Import your item list from Excel or CSV, and import past invoices from CSV. You can export everything back out at any time too.
Does BillZ work on my phone?
Yes. BillZ runs in the browser on any phone, tablet or laptop, so there’s nothing to install. Offline billing that syncs when you’re back online is coming as an add-on for yearly plans.
