Registration Usage Billing

Corsizio is a Canadian company dedicated to providing high-quality service at fair and competitive pricing for all our users.

As part of our commitment to provide you with a valuable tool and efficient service, including access to all features, data storage, and security, Corsizio uses simple pay-per-use pricing. As a bonus, we even waive your bill when your total registration usage is below the low-volume limit for new registrations in any given month.

Stay at or below 30 registrations per month = FREE
Go above 30 registrations per month = Pay for every registration that month

The fee is $0.15 per registration (varies by currency - see table below).

How does pay-per-use pricing for usage billing work?

Any registrations you process on Corsizio are all subject to the pay-per-use fee for each new registration, as listed in the cost table below by currency.

To enable usage billing, you need to add a valid payment card to your account to receive registrations beyond the low-volume limit. No other payment methods are accepted for usage billing besides credit or debit cards authorized for online purchases. Your payment card will be automatically charged right after the billing month's cycle finishes for all registrations processed that month.

Here is how the registration usage is billed:

0-30 registrations per month = FREE (entire bill waived)
31+ registrations per month = Charged for ALL registrations that month
If you do not enable billing, you can accept up to 30 registrations per month.

NOTE — Once you exceed 30 registrations in a given month, you are billed for every registration from the 1st one, not just those above 30, for that month.

Corsizio will send an email alert if the account's billing is not enabled when it is approaching and when it reaches the low-volume limit for any given month.

If the account reaches the low-volume limit within a month and either billing is not enabled or a valid payment card is not on file, the system will stop accepting new registrations for the account. This limit will be removed when you enable billing; otherwise, it will reset at the start of the next billing cycle.

NOTE — Registration usage billing applies to all types of registrations processed, regardless of registration status or online payment processing fees.

What is the per-registration fee rate?

The fee per registration depends on the payment card's associated country or region and currency, as shown in the table below.

Card Country / Currency	Fee per registration
United States — USD	$0.15 USD
Canada — CAD	$0.15 CAD
Australia — AUD	$0.15 AUD
Singapore — SGD	$0.15 SGD
United Kingdom — GBP	£0.15 GBP
European Union — EUR	€0.15 EUR
Mexico — MXN	$1 MXN
Other possible countries The default billing currency is USD for other possible countries or regions.	$0.15 USD

Sample monthly cost

The table below illustrates a sample case over six months for the USD usage billing fee of $0.15 per registration, reflecting any months in which registrations did not exceed the low-volume limit. Note that when registrations exceed 30 in a given month, ALL registrations for that month are billed, not just the excess.

Billing period	Total new registrations	Calculation	Amount billed
January	23	Waived (≤30)	$0
February	71	71 × $0.15	$10.65
March	26	Waived (≤30)	$0
April	4	Waived (≤30)	$0
May	108	108 × $0.15	$16.20
June	30	Waived (≤30)	$0

Common Billing Misconceptions

❌ WRONG: "I only pay for registrations above 30."
✅ CORRECT: "I pay for ALL registrations when I exceed 30 for the month."
❌ WRONG: "The first 30 registrations are always free."
✅ CORRECT: "The registrations are free ONLY if you stay at or below 30 for the month."

How do I get billed?

To enable billing and remove the low-volume limit on your registrations, visit the Billing & Usage area in your Corsizio Settings and add a debit or credit card for your billed usage. Accepted debit and credit cards include Visa, Mastercard, and American Express.

At the end of the month, if your total usage exceeds the low-volume limit, your payment card will be charged accordingly, and you will receive an email invoice receipt for that month's usage.

You can access and download your past invoice receipts in a PDF format from within your account's Billing & Usage area at any time. If you have multiple Corsizio accounts, please ensure you are logged in to the correct account for the billing receipt you need.

Please note that you may see slight differences between the information on your invoice for that month and in your report dashboard due to time zone adjustments.

Is usage billing subject to any taxes?

Corsizio is a company based in Ontario, Canada, and our service may be used to accept online registrations by customers who come to us from a few other countries or provinces.

If you are located in Canada, your invoice total is subject to Ontario's 13% HST.
If you are located in Europe, including the United Kingdom and Ireland, use the reverse charge mechanism for your VAT remittance. The European Commission DG Taxation web page provides additional information. Corsizio does not have a European business presence.
If you are located in the US, Australia, New Zealand, or any other country not mentioned above, your bill will not include any taxes.

What counts as a registration?

Every newly added registration counts toward registration usage billing. This includes:

All registrations submitted automatically by the attendee (registrant, student, trainee, parent, camper, etc.)
All manual registrations that are entered manually from your Corsizio account by you or one of your account users.
All waitlist registrations, whether they are automatically or manually submitted.

If you cancel or delete a registration, it still counts toward your total usage for the month it was registered, as Corsizio has already processed it. We do not charge you anything extra to process a registration cancellation or deletion.

You can view your current and historical usage trends and data under Reports within your Corsizio account.

Does usage billing apply to free, charity, or not-for-profit events?

Yes, if your registration usage exceeds the low-volume usage. We aim to provide everyone equally with an ultra-low, highly discounted, pay-per-use, and cost-effective model for higher-volume needs and free usage for low-volume needs. This means all our users get access to all the features, support, security, data storage, and service value regardless of the type or amount of events they offer.

What happens if you disable usage billing?

If you decide to disable your billing at any time during a billing cycle, your account will continue to accept unlimited registrations until the end of the month, and your final bill will be at the end of that month's billing cycle. At the end of the month, you will receive your final invoice.

Going forward, your account will again be subject to the low-volume limit, meaning that you can receive up to 30 registrations each month without enabling usage billing.
If you disable billing during the billing cycle and do not wish for your registration usage or bill to increase, you must take action to stop accepting new registrations, such as unpublishing all active events.
If you decide to delete your entire account while billing is enabled, the system will immediately process a charge for your final invoice, if applicable, and close the billing cycle.

Keep in mind that you can keep billing enabled even if you don't use Corsizio for several weeks or months at a time, or if you only use it for a few registrations. You will not be charged if usage is very low or nonexistent, as described in this document.

What happens if your payment card expires during a billing cycle?

If the payment card on file expires during the current billing month, the account can still receive up to 30 registrations that same month without any interruptions. However, if you plan to receive more than 30 registrations that month and no new valid card is added to your account before your account exceeds 30 registrations, the system will block further registrations (over 30) because it has no valid card to charge for them.

Our system bills your payment card at the end of the billing cycle, which is generally on the 1st of the following month. Therefore, a card that expires during the billing month's cycle will not work. This is why a payment card needs to be updated before the month it expires, or at the latest during that month, but before the account reaches 30 registrations that month, to prevent a registration block on the account.

To ensure an uninterrupted registration service, a different valid payment card can be added to the account temporarily if you are having trouble with your bank or organization obtaining a new valid version of the expired card.

NOTE — If your billing card has not been used for many months and the account's usage has been low, the system will prompt you to update the card to keep usage-based billing enabled for security reasons. Otherwise, it will act as described above, with usage billing disabled and no new registrations allowed above the low-volume limit in any given month. It is essentially an expired card from the system's perspective, which protects your account's usage and its billing until you update the payment card to re-enable billing.

What happens if your billing payment fails?

If your account's billing payment for the previous month's usage on Corsizio was declined by your card issuer, it may be due to certain card restrictions, card changes, or insufficient funds. It is never Corsizio that is declining your card, but your bank. Therefore, the best way to solve this is to contact your card issuer for more information and to clear the issue. You can also change your billing card to a different one to clear the outstanding charge promptly, and the payment will be retried immediately.

NOTE — Corsizio is a company based in Canada, and a common reason for a failed payment is that your payment card company or bank does not allow cross-border usage. If this is the case, you will need to contact your credit card company or bank to authorize the transaction.

As an online service that uses a pay-per-use pricing model for registration usage, payment is due and expected immediately upon the end of each billing cycle. If your payment fails and you experience any delay in promptly resolving an outstanding payment, it is essential to communicate with us to let us know accordingly, or you risk the automated system locking your account from further use. Upon a failed usage billing payment, our system will retry the payment again in a few days after the last failed attempt, but only up to 3 times. We hope you can resolve the issue before then and prevent your account from being automatically locked. Multiple failed payments due to insufficient funds or unauthorized card use will result in the permanent suspension of your account.

For more information about failed payments for you or your customers, please read the help document titled Failed Payments.

Why do I see a different or additional charge on my bank statement than on my Corsizio invoice?

Corsizio always and only charges and receives exactly what was on your invoice from us. There are no extra or unexpected charges, and no exchange rate fees. However, some small banks or credit unions located outside of Canada choose to add and charge their customers a "foreign transaction fee" or an "international transaction fee" (anywhere from 0.5% to 3%) just for making a purchase from a foreign company, even when the customer is being charged in their own currency, and no currency conversion is taking place. This may appear on your bank statement as an extra fee on its own line, or your bank may bundle it with our valid service charge, making it seem that Corsizio charged you more than it actually did.

Although Corsizio is a Canadian-based company, we are able to charge most of our international customers directly in their country's currency, so there is never any currency conversion for you. (Please refer to the Per-Registration Fee Rate table above.)

It is very unfortunate and a bad practice for banks to add their own fees to the customer's valid billed amount, as it does not accurately reflect what the customer was charged by the company with whom they transacted.

If this ever applies to you, please be sure to contact your payment card issuing bank about any such "foreign transaction fees" or "international transaction fees", as we have no control over such bank fee matters.

What happens if you dispute a valid billing charge from Corsizio?

When you choose to enable billing by adding a payment card to your Corsizio account to accept registrations above the low-volume limit in any given month, the account owner and all parties that are involved in managing the Corsizio account agree to the Usage Billing terms outlined above. As such, you are responsible for maintaining the account in good standing.

If anyone from your organization disputes a valid Usage Billing charge from Corsizio that was charged to the payment card your organization has added to your Corsizio account, a legal dispute process is initiated involving the payment card issuing bank, Corsizio, and our payment processor, Stripe. Wrongful disputes normally take one to three months to resolve and include non-refundable dispute processing fees our payment processor charges Corsizio, administrative costs Corsizio incurs to submit required documents for the wrongful dispute, and a possible suspension of the Corsizio account that disputed the valid charge.

Your Corsizio Account responsibilities in case of a dispute for a valid charge:

First, the payment cardholder who disputed the valid charge from Corsizio must contact their bank to reverse the wrongful dispute.
Second, the account with the disputed valid charge for usage billing from Corsizio is responsible for paying the outstanding amount of the valid charge (which their payment card bank returned to them), as well as a $30 USD wrongful dispute fee to Corsizio upon the initiation of the dispute process.
Failure to withdraw the wrongful dispute and pay the valid outstanding amount for your Usage Billing, along with the wrongful dispute fee, will result in the suspension of the Corsizio account, preventing any further use until all outstanding payments are settled.

Please note that disputing a valid charge is a serious matter that puts the payment cardholder's reputation at risk and can negatively impact valid charges from the merchant. Therefore, if you or any members of your Corsizio account or organization have any questions about Corsizio's registration usage billing fees or charges, please be sure to contact our support team first.
