Pricing and Payment
This page covers what you need to know when using WhaTap monitoring services on a paid plan. It explains where to check your charges, how to pay them, and how charges are calculated.
To keep using the service after your free trial ends or after you exceed the free tier, register payment information and convert your projects to paid. Conversion happens per project. You can select specific projects or convert all of them at once. For plans and per-product metering rules, see WhaTap Pricing.
Checking charges
The screen you need depends on what you want to check.
| What to check | Screen |
|---|---|
| Estimated charges for this month | Invoice Preview |
| Billing and payment records through last month | Billing and Payment History |
| Usage across all projects (without amounts) | Project Usage Preview |
| Daily and hourly usage for a single project | Usage |
| Prepayment balance and deductions | Prepayment |
This month's charges accumulate up to the time you check, so the amount changes each time you view it. Check the final amount in Billing and Payment History after billing is confirmed on the first day of the following month.
Making a payment
You can bill in KRW, JPY, or USD. Available payment methods depend on the currency you select.
| Billing currency | Payment method |
|---|---|
| KRW | Credit card(Nicepay) or Bank transfer |
| JPY, USD | Credit card (Stripe) or Sending invoice |
Bank transfer means transferring the amount based on the invoice. To receive a tax invoice, prepare your business registration certificate and a recipient email address in advance.
For how to register and change these, see Payment Information.
Invoices go to the recipient email address you entered in payment information. If you have a prepayment balance, it is deducted from the billed amount first. Any amount left unpaid carries over as an outstanding balance and is added to the next invoice.
How charges are calculated
WhaTap monitoring services charge by the hour for what you use. The base hours for each month equal the number of days in that month multiplied by 24.
Usage is aggregated per project and per product from the first day of each month in UTC (9:00 AM on the first day in KST). Each product has its own metering unit, such as CORE, HOST, SESSION, or CONTAINER. This aggregated value is the Metered units.
The Metered units is multiplied by the product unit price to calculate the usage fee, and any discounts or promotions apply to that amount. The total billed amount is the usage fee plus VAT plus any outstanding balance.
Billing owner
When several people share an account, you need to decide who receives the charges.
You can assign one billing owner per organization, per group, and per project. Usage fees are billed to the account assigned as the billing owner.
If a project has no billing owner, the charge goes to the group; if the group has none either, it goes to the organization's billing owner. When only the organization has a billing owner, charges for every group and project under it go to that owner. For a managed service provider (MSP) that manages customers as groups, assigning a billing owner per group lets you split charges by customer.
Billing data is created in the early morning on the first day of each month. The billing owner assigned at that moment is fixed as the account to be billed for that month and stored with the billing data. Changing the billing owner mid-month therefore does not change an invoice that has already been created; the new owner is billed from the next invoice onward.
Organizations and groups are units for assigning a billing owner, not units for calculating charges. An amount shown per organization or group is the sum of the amounts calculated per project.
To assign a billing owner or hand it over to another account, see Transferring billing permission. For how to assign one per unit, see Organization Management and Group Management.
