Troubleshooting

Fixes for the most common snags — OTP not arriving, editing a sent invoice, an invoice that won't send, pay links asking for a payout method, GST that looks wrong, and trial/plan-expired prompts.

Most issues have a quick, self-serve fix. Find your symptom below, follow the steps, and you'll usually be unblocked in a minute. If not, head to Contact & Support.

I didn't receive my OTP

Sign-in codes are 6 digits and expire in about 5 minutes. There's no password — you always sign in with a code.

1Wait for the resend countdown to finish, then tap Resend for a fresh code.
2Double-check the phone number or email you entered is correct.
3Look in spam, promotions, or blocked-SMS folders.
4Try the other channel — if WhatsApp/SMS isn't arriving, sign in with email OTP instead (or vice-versa).

Note

Verification codes are sent from noreply@invoicekaro.com. Add it to your contacts so codes don't get filtered.

Signing in with a 6-digit OTP — no password needed.

I can't edit a sent invoice

This is by design. Drafts are editable; sent invoices are locked so your records stay tamper-proof.

1Open the invoice from the Invoices list.
2If it's still a draft, edit it freely and then send.
3If it's already sent, cancel it and recreate a corrected invoice — you can't edit it in place.

Tip

Use drafts to get everything right before sending — once sent, the only fix is cancel + recreate.

My invoice won't send

Sending is driven by each customer's notification preferences and contact details. If a channel has nothing to send to, it can't go out.

1Open the customer and confirm they have the right contact for the channel — an email for Email, a phone number for WhatsApp/SMS.
2Check the customer's per-channel notification preferences (SMS / WhatsApp / Email) are enabled for the way you want to send.
3Pick a channel the customer can actually receive on, then resend. See Sending invoices.

Note

Email invoices are sent from billing@invoicekaro.com with the PDF attached — ask customers to allow that sender if they don't see it.

The pay link says "add a payout method"

A pay page can only show how to pay once you've added a payout method. Without one, there's nothing for your customer to pay into, so copying a pay link nudges you to set one up.

1Go to Profile → Payment Details.
2Add a UPI ID and/or a bank account (account number, IFSC, bank name).
3Optionally upload a UPI QR image.
4Save, then copy the pay link again — the pay page will now show UPI and bank options. See Set up payouts.

The GST on my invoice looks wrong

InvoiceKaro derives CGST+SGST vs IGST automatically — almost always a 'wrong tax' is really a mismatched State of Supply.

1Open the invoice and check the State of Supply against your business state (Profile → business profile).
2Same state → CGST + SGST; different state → IGST. Correct the State of Supply if it's set wrong.
3Confirm each line item's GST % and any per-item discount are right.
4If the invoice is already sent, cancel and recreate it with the correct State of Supply. See Creating invoices.

Warning

Your business state lives in your business profile. If that's wrong, every invoice's tax split will be off — fix it there first.

I'm seeing a trial- or plan-expired prompt

If your free trial has ended or your plan lapsed, the app may block creating and sending invoices (you might see a 402 / upgrade prompt). Your data is never deleted.

1Go to Profile → Subscription (or open Plans & billing).
2Choose a plan — monthly or annual — and upgrade to restore invoice creating and sending.
3Check current prices on the pricing page.

Important

After a trial or lapsed plan your data stays safe — you just need an active plan to keep creating and sending invoices. Billing questions? Email billing@invoicekaro.com.
