A charge is a request for a fixed amount, payable once. The **Charges** page lists every charge of the current mode. ## Create a charge Use this to bill a customer by hand. Enter the amount in sats. To price the charge in fiat, select the arrows next to **sats**, enter the amount, and select **USD** or **EUR** in the **Currency** field. The sats amount locks at creation. **Reference** is for you, for example your order number. Bark Pay shows **Description** to the customer at checkout. Both are optional. Bark Pay then offers every payment method that fits the amount. Select **Lightning**, **On-chain**, or **Ark** to restrict the charge instead. The charge detail opens with its payment details and checkout link.

Lightning starts at 1 sat, and Ark and on-chain at 546 sats. The Ark server's maximum VTXO size also caps Lightning and Ark from above. On **Automatic**, Bark Pay offers only the methods the amount fits. If you restrict the rails yourself, Bark Pay refuses the charge and names the limit. ## Share the payment details Two ways to get paid: * **Checkout link:** Select **Open checkout** to preview the [hosted checkout page](/docs/bark-pay/checkout), or copy its URL and send it to your customer. * **Payment rails:** Select the **Lightning**, **Ark**, or **On-chain** tab to show that method's QR code and copy its invoice or address, for example to display at a counter.

Filter it with the **All statuses** dropdown, and select a row to reopen its payment details: | Status | Meaning | | - | - | | Pending | Created, no payment received yet. | | Paid | The full amount arrived before expiry. | | Paid late | The full amount arrived after expiry, in one payment or as a top-up on an underpaid charge. | | Underpaid | Less than the amount arrived. The payment details stay open until expiry so your customer can top up, and a later top-up still counts. | | Overpaid | More than the amount arrived, including an extra payment on a charge that was already paid. | | Expired | The charge reached its expiry without receiving anything. Bark Pay closes its Lightning invoice, but an Ark or on-chain payment that arrives afterwards still settles it. | | Cancelled | Your server cancelled the charge through the API. Bark Pay records any bitcoin that arrives on it afterwards, but the status stays cancelled. | Lightning and Ark payments settle within seconds. An on-chain payment settles once its transaction has one confirmation, so expect a wait of about ten minutes on that method. The dashboard has no cancel button. To cancel a pending or underpaid charge, use the [cancel endpoint](/docs/bark-pay/integrate#cancel-a-charge) with a secret API key. To accept a payment that lands a few sats off the amount, set an [amount tolerance](/docs/bark-pay/settings#rates). Payments within it count as paid instead of underpaid or overpaid.
