An invoice number is a unique sequential identifier of each finalized invoice. Draft invoices do not have an invoice number.

Use automated invoicing when you want streamlined, hands-off billing:

Create one-off invoices when you need to bill outside regular subscriptions:

Turnstile does not have a credit note feature or a way to specifically track credit. The best way to issue a credit to your customer is to deduct the credit amount from their next invoice. You can do that by adding a discount in the amount of the credit.

Create invoice allows you to create a one-off invoice.

Most invoices are generated as a result of subscriptions. One-off invoices allow for charging one-time items without the need to amend the subscription. For example, a late payment fee.

You can create a one-off invoice from several locations in Turnstile:

There is no setting that updates the memo, footer, or header for an existing subscription as a whole. Each draft invoice carries its own memo, footer, and header, set when the subscription was created, and there is currently no bulk or subscription-level way to change them.

To update these fields, edit each draft invoice individually:

This only works while the invoice is still a draft. Once an invoice is issued, its memo, footer, and header cannot be changed.

Updating a draft invoice this way only affects that invoice. It does not carry forward to other draft invoices on the same subscription, and it does not change what future invoices for that subscription will use.

To change the default memo, footer, or header that new subscriptions start with going forward, edit the default invoice settings. This does not affect subscriptions that already exist.

The due date is set based on the invoice generation date + net terms. Net terms are set on the subscription.

Invoices cannot be marked as void or uncollectible until they have been issued. If you would like to remove an invoice before it has been issued, you can cancel it.

You can find an invoice on an individual customer page or, if you know the invoice number, you can use the global search bar in the top right.

Yes. On the customer page, edit Billing info and enter the email addresses in the CC email addresses section.

Note: Adding a CC to invoice emails is only available when using Turnstile's default invoicing. If you are currently using Stripe Billing (legacy feature), you can add additional email recipients after the invoice is issued in Stripe.

The resolved status of an invoice cannot be changed once it is set. If a voided invoice needs a corrected replacement, use void and reissue.

No, you cannot un-void an invoice. To issue a corrected replacement, use void and reissue.

Invoices associated with an upcoming subscription that came from a renewal will appear on the customer page when the service start date is a month away.

If you are trying to change the issue date for a single invoice, click the individual invoice to navigate to its page, then click Target issue date to change the date it will be sent to your customer.

Note: Target issue date can only be edited if the invoice is in Draft.

If you need to change the invoice generation for all invoices associated with an active subscription, you will need to Amend the subscription, then select your preferred Invoice generation schedule in the Billing section.

Yes. Automatically charge controls whether Turnstile collects payment without the customer's action, and Auto-charge triggers on controls when that charge happens.

To set this up for new subscriptions moving forward:

These settings apply account-wide by default, but automatically charge and its trigger can be overridden on an individual quote, subscription, or invoice.

​

Payment terms and automatically charge are separate settings and do not affect each other.

Payment terms control an invoice's due date. Turnstile calculates the due date as the invoice generation date plus the payment term. Due upon receipt sets this to zero days. There is no account-wide default for payment terms. Payment terms are set in a plan's billing details tab (applies to quotes and subscriptions created from that plan) or individually on a quote, subscription, or invoice.

Automatically charge controls whether payment is collected without customer action. This setting lives under Settings > Default invoice settings > Payment collection > Collect payments for me > Automatically charge. This default applies going forward, but automatically charge can be overridden on an individual quote, subscription, or invoice at any time. When enabled, Stripe charges the customer's payment method on file according to the selected auto-charge trigger. If no payment method is on file, Turnstile emails the invoice instead.

Auto-charge triggers on controls when that charge happens: Auto-charge on issue date fires the charge as soon as the invoice is issued, or Auto-charge on due date fires the charge on the invoice's due date. A customer with net 30 terms and Auto-charge on due date selected is charged 30 days after issuance, on the due date. A customer with the same terms and Auto-charge on issue date selected is charged at issuance, regardless of payment terms.

Dunning is the process of communicating with customers to collect payment. Turnstile automates this process through automated invoice collection.

Invoices remain in the in progress step until the usage period for the product or service has closed.

If the payment is successful, the billing contact is emailed a receipt from Stripe. If the payment cannot be completed, the billing contact will receive an invoice email asking for the payment.

No. There is no way to bulk update invoice generation settings for multiple customer subscriptions. Each subscription would need to be amended in order to edit the invoice generation settings.

There is no deadline. Invoices that include usage products will not be sent to customers if no usage data has been added for a given billing period.

For added confidence, we recommend toggling on the Require invoice approval setting for usage-based subscriptions so your usage invoices have a built-in approval process.

Invoices that include usage products will not be sent to customers if no usage data has been added for a given billing period, even if the automatically issue invoices setting is enabled for the related subscription.

No, the usage pricing types (usage, committed usage, and percentage) are not available when creating one-off invoices.

When billing includes automated usage, late-arriving usage events can trigger a follow-up invoice rather than rolling into the next billing period. This keeps each invoice tied to the service period in which the usage occurred.

No. Usage is tracked at the customer and product level, not at the subscription level. If a customer has more than one active subscription for the same product, entering a usage event applies to all of those subscriptions and their invoices. To bill usage separately for the same product, use separate customer records.
