# Mobile farm payment model and pricing
## Balance \{#balance}
To pay for a mobile farm, a [unified balance](/balance-and-payments/balance.mdx#united-balance) or [main balance](/balance-and-payments/balance.mdx#balances-by-service-type) is used, depending on the type of balance in your account.
You can pay for a mobile farm with different [types of funds](/balance-and-payments/balance.mdx#funds-types): primary funds or bonuses.
Before adding devices to a mobile farm, [top up your balance](/balance-and-payments/manage/top-up-balance.mdx).
## Billing \{#billing-options}
When adding a device to the mobile farm, you must select a [billing option](#billing-option-types). The billing option determines the duration of the paid period, the payment amount, and the [payment model](#payment-model).
The first paid period starts from the moment the mobile device is added to the mobile farm. When the paid period ends, the mobile farm device is automatically renewed for the same period. If necessary, you can [change the billing option](#change-billing-option). When switching to a different billing option, the [billing option change principle will be used](#change-billing-option-principle).
### Billing types \{#billing-option-types}
* per-minute;
* per-hour;
* 1-month subscription.
### Billing change principle \{#change-billing-option-principle}
If you switch from a billing type with a shorter paid period to one with a longer one, the billing will be changed immediately.
:::note
For example, you switch from per-minute billing to a 1-month subscription. Payment for one month of device usage will be charged immediately. Payment for the minutes spent will be charged at the end of the hour.
:::
If you switch from a billing type with a longer paid period to one with a shorter one, the billing will change only once the paid period ends.
### Change billing \{#change-billing-option}
1. In the [Control panel](https://my.selectel.ru/mobile-farm/), on the top menu, click **Products** and select **Mobile Farm**.
2. Go to the **Devices** section.
3. In the menu of the device, select **Change Billing Option**.
4. Select a [billing option](#billing-options).
5. Click **Save Changes**. When switching to a different billing option, the [billing option change principle will be used](#change-billing-option-principle).
## Payment model \{#payment-model}
The payment model depends on the [billing option](#billing-options) you selected.
Per-minute and per-hour billing
For mobile farm devices with per-minute or hourly billing, the pay-as-you-go payment model is used. Funds are deducted from your balance every hour for the previous hour of device usage. All mobile farm devices are charged for, even if you are not using them. If you no longer need a mobile farm device, [delete the device](/mobile-farm/manage/delete-device.mdx).
:::note
For example, if you ordered a mobile device with per-minute billing at 12:20 and deleted it at 12:50, the payment for 30 minutes of use will be charged at 13:00.
If you ordered a mobile device with per-hour billing at 12:20 and deleted the device at 13:10, at 14:00 you will be charged for two full hours, 12:00-14:00.

1-month subscription
Mobile farm devices with a 1-month subscription are paid for with a one-time payment once per month. When adding devices, the payment for the first month is charged from the balance, and subsequent payments are charged automatically at the beginning of each following month of device use.
During the paid period, you can replace a device with any other one from the list of available mobile farm devices. When replacing a device, you do not need to pay for the subscription again.
When paying, bonuses are deducted first, followed by primary funds. If there are insufficient bonus funds, the remainder is deducted from the primary funds.
:::note
For example, a mobile farm device costs 3 000 ₽/month. You have 2 500 ₽ in primary funds and 500 ₽ in bonus funds. Then, when the service is renewed, 500 ₽ will be deducted from bonus funds first, and then 2 500 ₽ from primary funds.
:::
You can view already paid services in the [Control Panel](https://my.selectel.ru/balance/services/): from the top menu, click **Billing** → **Services**.
Read more about payment in the [Terms of Service for Specific Services: Mobile Device Farm](https://files.selectel.ru/docs/ru/conditions-mobile-farm.pdf) document.
To disable mobile device billing via a 1-month subscription, [disable the monthly payment](/balance-and-payments/payment-models.mdx#disable-payment). Disabling the monthly payment constitutes cancellation of the service.
## Blocking resources if there are insufficient funds on the balance \{#insufficient-balance}
If at the time of the charge there are insufficient funds on the balance for full payment, the service blocking conditions depend on the billing type:
* per-minute or per-hour — devices are blocked immediately and deleted without the possibility of recovery;
* 1-month subscription — devices can be used on credit for one month. If you do not [top up your balance](/balance-and-payments/manage/top-up-balance.mdx) during this month by an amount sufficient to pay off the debt and the next month of device usage, the devices will be blocked and deleted without the possibility of recovery.
Projects are not blocked or deleted; you can delete a project via the [Cloud Platform Projects and Resources API](/api/cloud-projects-and-resources/).
To avoid missing balance top-ups, you can [configure balance notifications](/balance-and-payments/manage/balance-notifications.mdx).
## View consumption \{#view-consumption}
You can view consumption and payment charts for mobile farm infrastructure in the [Control Panel](https://my.selectel.ru/mobile-farm/consumption): from the top menu, click **Products** → **Mobile Farm** → **Consumption** section → **Consumed** and **Paid** tabs.
You can view consumption for specific projects and devices. Consumption and payment charts can be viewed for a specific time period or sorted by days, weeks, months, or years.
To export consumption and payment details in `.csv` format, click **Download CSV** and select how rows will be grouped in the export (by hour, day, week, month, year).
All [resource blocks](#insufficient-balance) are shown on consumption and payment charts.
## Prices \{#prices}
The price for mobile farm devices is the same for all devices and does not depend on the manufacturer or operating system. You can view the price in the [Control Panel](https://my.selectel.ru/mobile-farm/) when [adding a device](/mobile-farm/add-device.mdx).
## Accounting documents \{#reporting-documents}
After payment, you can [request accounting documents](/balance-and-payments/accounting-documents.mdx).
