GridInvoiceBack to home30-day refunds
Altamira Systems offers a full refund of the price paid for an initial GridInvoice license or an optional update renewal when you request it within 30 calendar days of that purchase. You do not need to prove a software defect. Each renewal has its own 30-day window. Purchases are not open yet; this policy applies when checkout opens.
How to request a refund
Contact us using the support page or reply to your Gumroad purchase receipt. Include your purchase email, receipt or order reference, and whether the request concerns the original license or a renewal. Do not send card numbers, passwords, or client invoices. The date you send the request determines whether it is within the window.
We respond to email within 24 hours and handle approved refunds through Gumroad to the original payment method where supported. The time for funds to appear depends on Gumroad and your payment provider; it is separate from our response commitment. Taxes and currency conversion are handled by the checkout/payment provider. We do not charge a refund administration fee.
What happens to your license
Original purchase refunded: the license granted by that purchase ends when the refund is completed. Stop using that installation and uninstall the software after exporting any records you need. You continue to own your invoices, PDFs and other business data; we do not remotely delete those files.
Update renewal refunded: your original permanent license remains valid. The update coverage added by that renewal is withdrawn; coverage and eligible versions return to what your other non-refunded purchases provide. We will help identify the version you can keep using. We do not erase your business records as part of a refund.
These are refund conditions, not a promise of instant remote deactivation. Expiry of an update window, declining a renewal, or a temporary billing outage does not cancel a non-refunded permanent license.
Pending payments and other rights
If you have not submitted payment, you may leave checkout without completing the purchase. If a payment is pending or already submitted, contact us; a cancellation may need to be processed as a refund. There is no recurring subscription to cancel.
Contact us about duplicate or unauthorized charges even if 30 days have passed. This policy does not limit any mandatory consumer rights or remedies available under applicable law.
