# Contribute and manage memberships

This guide helps supporters choose the right support model and manage ongoing support responsibly.

## One-time contribution vs membership

Use one-time support when:

* You want to support a specific moment or event
* You prefer full flexibility

Use membership when:

* You want ongoing support
* You value recurring member benefits where offered

## Before contributing

Check:

* What the competitor is currently raising funds for
* Whether support is one-off or recurring
* Any supporter benefits described on profile

## Managing memberships

If you join a membership:

* Review billing frequency
* Keep payment details current
* Track member updates from the competitor

## Cancelling recurring support

If you need to stop recurring support, follow cancellation guidance for memberships in platform and legal documentation.

## Troubleshooting

### I expected one-off support but was billed again

* Check whether membership was selected at checkout
* Review active subscriptions and cancel if needed

### I cannot find contribution history

* Confirm you are signed in to the same account used at payment
* Check for confirmation emails and transaction details

## FAQ

### Is one-time support refundable?

Refer to platform terms and support guidance for refund-related scenarios.

### Can I switch between one-time and recurring support?

Yes. You can choose either model based on your goals and budget.
