Everything about your subscription is under **Settings → Billing** (`/admin/settings/billing`).

## Your plan

See your current plan, what it includes, and your AI credit balance. In the **Plans** list, pick a plan and choose **Upgrade** or **Switch to this plan** — see [Your plan, billing & AI credits](https://hexafloww.com/docs/getting-started/plan-billing-credits.md) for how plans and credits work.

## Payment

Recurring billing runs through Razorpay Subscriptions. If a payment fails you'll get email reminders and an in-app banner; unresolved, sending is eventually paused until the account is current.

## Invoices

Open **Payment history** for past charges, each with a PDF invoice download. Use these for your accounting.

## GST details (India)

Add your **billing profile** — legal name, address, and **GSTIN** — so your invoices are raised correctly with GST. A verified GSTIN means B2B tax invoices; without one, invoices still issue but as B2C.
