Invoices & Payments

ZenFlip makes it easy to manage your billing details, access invoices, and resolve payment issues. This guide covers everything you need to keep your account in good standing.

Viewing Your Invoices

To access your billing history:

  1. Go to Settings in the top navigation

  2. Select the Billing tab

  3. Scroll down to the Billing History section

You'll see a list of all past invoices, including:

  • Date - When the charge was made

  • Amount - The total charged (including any applicable tax)

  • Status - Paid, pending, or failed

  • Plan - Which plan the charge is for

Downloading Invoices

Click on any invoice to view the details, then click Download PDF to save a copy. Each invoice includes:

  • Invoice number

  • Billing date

  • Description of the charge (plan name, billing period)

  • Subtotal, tax, and total amount

  • Payment method used (last 4 digits of card)

  • Zentrovia Solutions company details

These PDF invoices are suitable for expense reports, accounting, and tax records.

Invoice Emails

ZenFlip sends an invoice email after each successful payment. The email includes a summary and a link to view the full invoice in your account settings. If you need invoices sent to a different email address (for example, your accounting department), you can add a billing email in your billing settings.

Updating Your Payment Method

To change the credit or debit card on file:

  1. Go to Settings > Billing

  2. In the Payment Method section, click Update Payment Method

  3. Enter your new card details

  4. Click Save

Your new card will be used for all future charges. The previous card is removed immediately.

Accepted payment methods:

  • Visa

  • Mastercard

  • American Express

  • Discover

All payment processing is handled securely through Stripe. ZenFlip never stores your full card number - only the last 4 digits for display purposes.

Updating Your Billing Address

Your billing address is used for tax calculation and appears on invoices:

  1. Go to Settings > Billing

  2. Click Edit next to the billing address

  3. Update your address details

  4. Click Save

Changes to your billing address apply to future invoices. Previous invoices retain the address that was on file when they were generated.

Failed Payments

If a payment fails, here's what happens and how to fix it:

What Triggers a Failed Payment

  • Expired card - Your card's expiration date has passed

  • Insufficient funds - The card doesn't have enough available credit

  • Card declined - Your bank has declined the charge (for fraud protection or other reasons)

  • Incorrect card details - The card number, expiration date, or CVC is wrong

What Happens After a Failure

  1. Immediate notification - You'll receive an email alerting you to the failed payment

  2. Automatic retry - ZenFlip automatically retries the charge after 1 day, 3 days, and 7 days

  3. Grace period - Your account remains fully functional during the 7-day retry window

  4. Account restriction - If all retries fail after 7 days, your account is downgraded to the free Explorer plan. Your publications and data are preserved, but paid features are locked.

Resolving a Failed Payment

To fix a failed payment before the retry window expires:

  1. Go to Settings > Billing

  2. You'll see a banner indicating the failed payment

  3. Click Update Payment Method and enter a valid card

  4. Click Retry Payment to charge the new card immediately

Once the payment succeeds, your account returns to normal with no interruption.

Contacting Your Bank

If your payment keeps failing despite having a valid card with sufficient funds, your bank may be blocking the charge. Try:

  • Calling your bank's support line and asking them to authorize charges from Zentrovia Solutions

  • Using a different card temporarily while you resolve the issue with your bank

  • Checking for fraud alerts - some banks flag international or online transactions and require you to confirm them

Tax Information

ZenFlip calculates and applies tax based on your billing address. Tax rates vary by location:

  • United States - Sales tax varies by state

  • European Union - VAT is applied based on your country

  • Other regions - Local tax laws apply where required

Tax is shown as a separate line item on your invoice. If your organization is tax-exempt, contact us at billing@zenflip.io with your exemption certificate, and we'll update your account.

Refunds

ZenFlip's refund policy:

  • Within 14 days of first subscription - Full refund available, no questions asked. Contact billing@zenflip.io.

  • After 14 days - Refunds are evaluated on a case-by-case basis. We're fair and reasonable - if something went wrong on our end, we'll make it right.

  • Annual plan cancellation - No partial refund for unused months, but your access continues through the end of the paid period.
