Payments & Refunds.
How online invoice payments work, what happens to your card details, and how refunds and billing questions are handled.
Last updated · 2026-07-24
Scope
This policy applies to invoices issued by Gravenstone Enterprises (“Gravenstone”, “we”, “us”) under an executed Master Services Agreement (“MSA”) and Statement of Work (“SOW”), and paid online through this site. The site itself sells nothing directly — there is no cart, no subscription, and no product checkout. Every online payment corresponds to an invoice for engagement work governed by a written agreement.
How payment works
When you pay an invoice, you are redirected to a checkout page hosted by Stripe, our payment processor. Your card details are entered on Stripe’s page and go to Stripe directly — they never touch our servers, and we never see or store your card number. We receive confirmation of the payment together with limited transaction metadata, as described in our Privacy Policy. A receipt is emailed to you after a successful payment.
Invoices are payable in the currency and amount stated on the invoice itself, by the due date shown there.
Refunds and credits
Whether a payment is refundable — in whole or in part — is governed by the executed MSA and SOW for the engagement the invoice belongs to, including any provisions on fees, termination, and credits.
Where a refund is due — for example, a billing error, a duplicate payment, or an overpayment — we issue it to the original payment method through Stripe. Refunds typically appear on your statement within five (5) to ten (10) business days of being issued, depending on your card issuer.
Billing questions and disputes
If you believe an invoice or a charge is incorrect, contact us first through the contact form on our home page with the invoice reference. We aim to resolve billing questions promptly, and speaking to us before initiating a card dispute with your issuer is almost always the fastest path to a correction.
Cancellations
Cancelling or winding down an engagement — and any fees, notice periods, or credits associated with doing so — is governed by the executed MSA and SOW, not by this page.
In the event of any conflict between this page and an executed MSA or SOW, the executed agreement controls. This page describes how payments are processed and how we handle refunds operationally; it does not create engagement terms. See our Engagement Disclaimer.
Changes
We may revise this policy from time to time. The current version is identified by the “Last updated” date at the top of this page.
