By subscribing to a Business Plan, some usage methods prohibited under "Prohibited Acts" are exempted. We will provide details on what you can do with the Ondoku Business Plan.

Username is the Addressee

The username becomes the addressee on the invoice.

If you have registered the username incorrectly,

  • Click on change username
  • Enter the desired username
  • Click register

You can change the username this way.

Since a quotation is issued simultaneously with the invoice, you can download it very easily if you need a quotation for internal approval processes.

If the username and the remitter's name are different, payment confirmation cannot be performed. Please be sure to let us know via the inquiry form.

In Case You Accidentally Created Multiple Invoices

Invoices can be easily created with a single button.

Because of this, you may accidentally create unnecessary invoices.

Deleting or canceling invoices cannot be performed by the customer.

If you have accidentally created multiple invoices, please contact us via the inquiry form with a request for deletion.

Quotations and invoices without payment or contact for more than 3 months will be deleted as expired.

If You Make a Payment While Multiple Invoices Exist

If a payment is made while multiple invoices exist and no invoice number is provided, we will activate the invoice for the corresponding plan with the most recent date.

Designated Bank Account

The designated bank for transfers is SBI Sumishin Net Bank.

Other accounts are currently being prepared.

As there is a branch name and account number, you can make transfers from other banks. Of course, transfers between SBI Sumishin Net Bank accounts are also easy.

Accounts other than SBI Sumishin Net Bank are currently in preparation. Please understand this in advance.

Timing of Plan Application

After confirmation of the transfer, the plan will be activated within 24 hours in principle.
If the username and the remitter's name are different, payment confirmation cannot be performed. Please be sure to let us know via the inquiry form.

* If you are in a hurry, we can activate the plan if you inform us of the approximate payment date, even before the funds arrive.
In that case, please contact us via the inquiry form after issuing the invoice.
Please note that if payment cannot be confirmed 3 days after the notified payment date, the account will be suspended.

In the annual plan via direct bank transfer, the plan will be displayed as "Free Plan" in the system.
This is because the annual plan lacks a payment ID required by the system, such as those for credit card payments.
Please rest assured that the plan is active once you receive the plan activation email.

What is Status?

Status represents the payment situation after the invoice is issued.

  • Awaiting Payment: The invoice has been issued and payment has not yet been made.
  • Unpaid: The payment date has been notified and the plan is activated, but payment is still pending.
  • Paid: Payment has been confirmed and the plan is active.

Once the status becomes Paid, the receipt can be downloaded.

Regarding Receipts

After the plan is activated, the status will change to "Paid," and you can download the receipt from the Invoice Issuance History.
