# Troubleshooting Payment Issues

# Troubleshooting Payment Issues

If you're seeing an error when trying to upgrade or pay for a Simplebooklet plan, here are a few things to try before reaching out to us.

## Common Fixes

**Try a different browser.** We support all major browsers including Chrome, Safari, and Firefox. If you're having trouble in one browser, switch to another and try again.

**Try a different card.** If your card is being declined, try a different one. We accept major credit cards as well as PayPal and Apple Pay.

**Check that you're on the right account.** If your account has lapsed or been cancelled, old renewal links won't work — you'll need to purchase a new plan from a fresh login. It's also worth checking whether you or someone on your team has a second account under a different email address, as you may be trying to pay on the wrong one.

**Clear your browser cache and try again.** Occasionally cached data can interfere with the checkout process.

## Still Not Working?

If none of the above resolves the issue, contact us via the chat icon and let us know:

- What error message you're seeing (a screenshot helps)

- What browser and device you're using

- What email address your account is under

- What plan you're trying to purchase

Our team will take a look and get you sorted out.
