应用费用

您可以收到四种不同类型的与应用相关的费用和抵扣额：

• 订阅费用 - 这些费用用于定期使用应用（例如月度订阅）。费用会显示在您的常规 Shopify 订阅账单上。

• 应用使用费用 - 这些费用不是固定的，具体取决于您的应用使用量或者与应用集成的服务的使用量（例如客户服务应用提供的交互数）。费用会显示在您的常规 Shopify 订阅账单上。

• 一次性应用费用 - 这些费用适用于由应用提供的特定服务（例如，将您的数据从一个平台单次迁移到另一个平台）。这些费用将显示在单独的账单上。

• 应用程序信用额度 - 在某些情况下，您有权获得应用程序信用额度，例如您在账单周期中途将付费应用订阅降级的情况。这些信用额度显示在您的 Shopify 订阅账单上，可用于支付 Shopify 的未来应用程序费用。

订阅

您需要按 Shopify 的 30 天订阅账单周期为订阅和使用应用付费。但您的应用具有单独的 30 天账单周期，这会对您在 Shopify 账单上看到的费用产生影响。

Shopify 账单周期

您将每隔 30 天收到一次 Shopify 订阅的发票，并为接下来的 30 天预先付款。例如，假设您在 4 月 5 日收到 Shopify 发票。由于 4 月有 30 天，该周期将于 5月 4 日结束。您需要在 5 月 5 日为第二个月的订阅付费。由于 5 月有 31 天，您需要在 6 月 4 日支付第三个月的费用。

应用账单周期

通过订阅向商家收费的应用按照 30 天的账单周期单独计费。此账单周期与 Shopify 订阅同时收费。有两种类型的订阅：

• 定期定价套餐

• 使用情况定价套餐

定期定价套餐

定期应用费用随下一张 Shopify 30 天发票费用一起收取。在下面的示例中，5 月 5 日的账单包括从 4 月 20 日到 5 月 20 日的重叠应用订阅。6 月 4 日的账单与此类似，包括 5 月 20 日到 6 月 19 日（因为 5 月有 31 天）的应用订阅。

在 Shopify 后台中，您可以查看哪些订阅（包括哪些应用订阅）具有定期费用。

如果您停止支付账单或关闭您的商店，Shopify 将冻结您的账户和您的定期应用费用。如果您重新开始启用付款或在 30 天内重开您的商店，Shopify 会将您的账户解冻，并且将恢复定期应用费用。

如果您使用 Pause 套餐暂停商店，则无需卸载您的应用。商店使用 Pause 套餐时，您的定期应用费用会被冻结，但重新开启商店或者商店升级为 Pause and Build 套餐时，费用会自动恢复。

使用情况定价套餐

如果您使用按使用情况计费的应用，则您始终需要在下一个账单中为使用应用付费。例如，在下图中，在 4 月 26 日创建的使用情况记录将显示在 5 月 5 日的账单中。自 5 月 15 日起的使用情况记录将显示在 6 月 4 日的发票中。虽然这两个使用情况记录与同一个应用订阅相关，但它们显示在两张单独的发票上。

考虑应用账单、卸载应用以及应用使用费时，请务必记住这些不同的账单周期。

虽然您在批准应用费用后会立即在账户上看到定期收取的应用费用，但这些费用并不需要立即支付。在您收到为期 30 天的 Shopify 订阅账单或您已超过账单起付金额时（以先发生者为准），将对您的账户收取定期应用费用。

卸载定期收费的应用

计划卸载应用时，请务必考虑应用账单周期。定期收取的应用费用在第一次批准应用费用时生成，然后会在应用账单周期的第一天生成。因此，即使您在安装应用后的一两天就将其卸载，账单上依然会显示费用。

应用使用费

应用使用费与应用的 30 天账单周期相关，表示使用应用所产生的费用。由于应用的账单周期不一定与 Shopify 的 30 天账单周期相同，因此可能会看到一个应用账单周期的使用费分摊到两个 Shopify 订阅账单的情况。考虑账单上的使用费时，您应考虑到不同的账单周期。

金额上限

产生使用费用的应用具有金额上限，可防止账单周期内的费用超过最高起付金额。若要在超过金额上限后继续使用应用，您需要同意新的使用费。这样可以防止您支付的使用费超过上限金额。

一次性应用收费

一次性应用收费适用于不定期计费的应用。所有一次性费用都在单独的账单上显示，这些费用不会出现在常规的 Shopify 订阅账单上。

App charges

There are four different types of app-related charges and credits that you can receive:

• Subscription charges - These charges are for recurring use of an app, such as a monthly subscription. They appear on your regular Shopify subscription bill.

• App usage charges - These charges are variable based on how much you're using the app or the service that it integrates with (such as the number of interactions provided by a customer service app). They appear on your regular Shopify subscription bill.

• One-time app purchases - These charges are for specific services provided by an app (such as a single migration of your data from one platform to another). They appear on separate bills.

• Application credits - You are entitled to application credits under certain circumstances, such as when you downgrade a paid app subscription partway through its billing cycle. These credits appear on your Shopify subscription bill, and can be used towards future application charges on Shopify.

Subscriptions

You are billed for your app subscriptions and app usage as part of Shopify's 30-day subscription billing period. However, your app has a separate 30-day billing cycle, which impacts the charges you'll see on your Shopify bill.

Shopify billing cycle

You are invoiced every 30 days for your Shopify subscription, and you pay in advance for the following 30 days. For example, suppose you receive your Shopify invoice April 5. Since April has 30 days, the cycle will terminate at the end of May 4th. On May 5, you are billed for the second month of your subscription. The third month payment is billed on June 4 since may has 31 days.

App billing cycles

Apps that charge merchants using subscriptions are billed on an independent, 30-day billing cycle. This billing cycle is charged for at the same time as the Shopify subscription. There are two types of subscriptions:

• Recurring pricing plans

• Usage pricing plans

Recurring pricing plans

Recurring app charges are billed with the next Shopify 30-day invoice. In the example below, the bill on May 5 includes the app subscription that overlaps from April 20-May 20. The bill on June 4th similarly includes the app subscription from May 20-June 19 (since May has 31 days).

From your Shopify admin, you can view which subscriptions, including which app subscriptions, have recurring charges.

If you stop paying your bills, or close your store, then Shopify freezes your account and your recurring app charges. If you start your payments again, or re-open your store within 30 days, Shopify unfreezes your account and your recurring app charges resume.

If you pause your store using the Pause plan, you don't need to uninstall your apps. Your recurring app charges are frozen while your store is on the Pause plan, but the charges resume automatically when you reopen your store, or if your store is upgraded to the Pause and Build plan.

Usage pricing plans

If you use apps that bill for usage, then you will always be billed for these usage events on the next bill. For example, in the diagram below the usage record created on April 26 will appear on the May 5 bill. The usage record from May 15 appears on the June 3 invoice. Although these two usage records are tied to the same app subscription, they appear on two separate invoices.

It's important to keep these different billing cycles in mind when considering app bills, uninstalling apps, and app usage charges.

Although you'll see recurring app charges on your account as soon as you approve an app charge, the charges aren't due immediately. Recurring app charges are applied to your account either when you receive your 30-day Shopify subscription bill, or if you exceed your billing threshold (whichever comes first).

Uninstalling apps with recurring charges

Make sure that you consider app billing cycles when you plan to uninstall an app. Recurring app charges are generated the first time an app charge is approved, and then on the first day of an app's billing cycle. Because of this, a charge will appear on your bill even if you uninstall an app only a day or two after you install it.

App usage charges

App usage charges are associated with an app's 30-day billing cycle and represent charges for app usage events. Because an app's billing cycle will not necessarily be the same as Shopify's 30-day billing cycle, it's possible to see usage charges for a single app billing cycle spread over two Shopify subscription bills. You should keep the different billing cycles in mind when considering usage charges on your bills.

Capped amounts

Apps that issue usage charges include a capped amount that prevents billing from exceeding a maximum threshold over the duration of the billing period. To continue using an app after exceeding a capped amount, you need to agree to a new usage charge. This prevents you from being charged for any usage over and above the capped amount.

One-time app charges

One-time app charges are for apps that aren't billed on a recurring basis. You'll see separate bills for any one-time app charges, and they won't appear on your regular Shopify subscription bill.
