# What payment methods do you accept?

## Card and PayPal

We support payment by credit card, debit card and PayPal for our recurring monthly, quarterly and annual subscription plans. We accept all major cards:

- Mastercard
- Visa
- American Express
- Discover
- Maestro

Payments are processed by Braintree Payment Solutions, so card details are entered in Braintree's own secure form and never stored by OptiMonk.

In the app a card shows up as **Credit card** and a PayPal account as **PayPal**.

## Bank transfer (proforma invoice)

Some accounts can pay by bank transfer instead of a card. With this option we send a **proforma invoice** for each billing period and no card is required.

Bank transfer is offered for annual subscriptions billed in Hungary that do not have a payment method on file yet, and it stays available for accounts already billed this way. If it is available for your account, you will see it as an option in Settings (see below); if you don't see it, card or PayPal is the way to pay.

## Shopify-billed accounts

If you subscribed through Shopify, your subscription is charged by Shopify and the payment method is read-only in OptiMonk: *Payment method changes for Shopify-billed accounts are managed in your Shopify admin.*

## Where to add or change your payment method

1. Click your name and avatar at the bottom of the left sidebar, then select **Settings**.
2. Open the **Billing** tab.
3. Go to the **Payment method** section.

- If you already have one, it is shown next to **Current:** — the masked card number and expiry, or your PayPal email address.
- If you don't, you'll read: *No payment method on file. Add a card or PayPal below to upgrade your plan.*
4. Fill in the secure payment form and click **Save payment method**.
5. If bank transfer is available for your account, two options appear above the form: **Card / PayPal** and **Bank transfer**. Choosing *Bank transfer* shows the note *Switch to bank-transfer billing. We send a proforma invoice each period — no card required.* and a **Switch to bank transfer** button.

💡 You can also pick the payment method while changing plans: the **Change plan** wizard walks you through *Plan → Billing → Payment → Summary*, and the **Order summary** step lists your plan, billing period, price, VAT and the payment method before you press **Pay & switch plan**.

## Where to find your invoices

Invoices live on the same **Billing** tab, in the **Invoice history** section. Each row has an **Order** number, a **Date**, a **Status**, a **Total** and a **Download** column. Depending on what was issued for that order you get an **Invoice** link, a **Proforma** link, or both; either one downloads the PDF.

**Please note:** the **Billing**, **Subscription** and **Usage** tabs are only visible to the owner of the account.

## If a payment is declined

When a charge fails, the **Subscription** tab shows a red notice — *Your last payment was declined.* — with an **Update payment method** link that takes you straight to the Billing tab, where you can enter new card details.
