An ecommerce crypto checkout should connect a trusted order total to an invoice and fulfill only a verified payment. Coinvay offers hosted checkout and integration source packages, but your store still needs inventory, shipping, fulfillment and payment-exception rules.
Reserve stock without treating checkout as payment
Create a pending store order and calculate its total on your server, including the shipping and discounts you actually offer. Store the linked invoice identifier. Decide how long to reserve stock and what to do if the quote expires before the buyer completes a transfer.
Imagine a hypothetical shop with one remaining item. Two buyers can open checkout at the same time; a payment link alone does not reserve that item. Use your store’s inventory controls, and define a resolution path if a late valid transfer arrives after stock has been released.
Verify before handing the order to fulfillment
A customer’s return to the store is a navigation event. Your backend must confirm the invoice state and match it to the pending order. Webhook delivery may be delayed or repeated, so a durable fulfillment marker should prevent duplicate shipping labels and repeated digital deliveries.
The WooCommerce package is an installable module, while other downloads may be developer kits. In particular, the Shopify adapter is not a universally approved, one-click payment app. Read the current package limitations, configure it in the actual store and test the platform’s complete order lifecycle.
Treat exceptions as part of checkout
Show clear instructions for asset, network, exact amount and time remaining. A customer sending from an exchange may face withdrawal minimums or a fee deduction; explain how to find the transaction hash when automatic detection needs assistance.
A return does not undo the original blockchain transfer. Review the return request, verify the customer’s refund destination and authorize any outgoing payment separately. Record the relationship between the original sale and the refund in the store so stock, receipts and support history remain consistent.
Practical checklist
- Calculate the order total on the backend.
- Test stock reservation and late-payment handling.
- Make fulfillment idempotent.
- Validate the exact platform package before advertising support.
Common questions
Will installing a plugin manage every store process?+
No. A payment integration does not replace inventory, shipping, access control or the merchant’s refund policy. Test how your platform and the package interact.
Should an unconfirmed transaction trigger shipping?+
Not under the standard verified-payment workflow. Wait for the invoice to be Paid and matched to the intended order.
