    Can I customize my invoicing URL?

    If you are a Pro/Enterprise user, you can. Go to Advanced Settings > Email Settings. Scroll down to the Invoice Link section and select Website. You’ll need to provide a link to your website, and embed the code on your relevant web page. Click on the small question mark icon next to the text field to get a copy of the code.

    How so I set up automatic reminder emails to send to clients whose invoices are still unpaid?

    Go to Advanced Settings/ Templates & Reminders. Scroll down to Reminder Emails. You can send up to three automatic reminder emails. Make sure to check “Send automatically” and define a time frame.

    Then customize each reminder email with your own message, subject header and formatting.

    What is the product library and how does it work?

    The product library is a list of popular services or items you frequently include in your invoices. For example, a product might be “one hour of graphic design”, with a set charge of $100. You can create and save as many products as you like. Then, when creating an invoice, the products will appear in a drop-down menu in the Item column. Select the product, add the quantity, and the line item cost is calculated automatically and added to the invoice.

    The product library feature saves you from having to retype information about your line items when you create or edit an invoice.

    How do I use the Tasks section?

    You can bill clients according to time spent on a project. Click the + sign on the Tasks tab in the main sidebar menu or open the Tasks list page and click New Task. Select the Client and Project from the drop down menus, then click Timer and Start to begin timing the project. To manually enter time spent on a project, check Manual.

    How do I set up online payments?

    To enable your customers to pay you online, you’ll need to set up online payments. You do this by integrating your Invoice Ninja account with a payment gateway. To set up online payments, go to Settings > Online Payments. Select the payment gateway you want, and follow the instructions. Each gateway setup will be a bit different. Click here to learn about all the available payment gateways.

    What is auto billing?

    Auto billing is a feature that securely stores the client’s credit card details, so you can automatically charge their card according to a pre-defined amount and frequency. Auto billing saves you loads of time and energy. Instead of sending an invoice and waiting for the client to pay, you can set up automatic recurring payments via their credit card.

    Which payment gateways support auto billing?

    Auto billing is available with WePay, Stripe and Braintree.

     

    How can I update a credit card that is already on file?

    First you’ll need to delete the old credit card. Go to Advanced Settings > Credit Cards & Banks. Delete the old card from the list, and add the new one.

    What is token billing?

    Token billing is the technical term for auto billing. Token billing enables credit card storage within a payment gateway, so the card can be charged at a later date.

Token/auto billing is available in your Invoice Ninja account via WePay, Stripe and Braintree.

    How do I know my API key?

    Your API Key is generally found in the Account Settings or personal details section of your payment gateway account (ie. Paypal.com, Stripe.com, Authorize.net, etc). Make sure to use your secret API Key, not the publishable API Key, and that your account is “live” and not in test or demo mode.

    What is the API request limit?

    The API limit is 100 requests per hour.
