Customers like to know what they're buying. Without any written proof of what they were charged for, they're likely to distrust the merchant’s pricing, which can lead to bad publicity for any business.
The invoice, which the seller issues to the buyer with details of a good or service the seller has provided, is one of the most important forms of business documentation. Having an opportunity to customize the invoice template, so that it matches the style of your business, is an essential feature for a great number of merchants selling online.
The Online Store provides an easy tool for editing invoices. You can add a personal logo to it, specify your business registration number and even change the whole invoice template.
To access your Invoice Settings, please, open your Online Store. Go to Settings > Invoice.
How to add a logo to the invoice?
Click the Upload invoice logo button and choose the file from your computer: 
Once added, the logo is displayed on the printable sample. You can print the sample to see, if it looks OK, and upload a different image by clicking Change Invoice Logo or you can click Remove Logo to remove the logo from your invoice.
How to add a business registration number to the invoice?
Displaying some kind of seller registration ID on invoices is required in most European and a few other countries. For instance, in the UK VAT registration number is required, P.IVA is obligatory in Italy, ABN - in Australia, etc.
Click the Set Tax ID button and insert the value to the editable field. If you click on ‘pencil’ icon, you will be able to edit the default name of the tax registration ID as well.
Once added, the tax ID will be displayed on all invoices in your store.
The specified Tax ID number will additionally be included to the email notifications sent to your customers by email. By default, the ID number is displayed in the footer of the letter:
How to edit the invoice template?
It’s possible to edit the invoice template with the help of HTML tags and regular expressions.
How do I know which variable or regular expression I need?
The invoice template uses standard HTML tags and special regular expressions for transferring order details to the invoice. You can add or remove the variables of these expressions, change their positions and make a custom invoice, precisely suiting your needs.
The invoice template uses the same collection of variables as improved Ecwid Mail Notifications.
How to remove the SKU number from the invoice?
For instance, to remove SKU number from the invoice, you need to delete the corresponding ${orderItem.sku} variable from the template.
Can I preview the changes I’m making?
The Online Store allows you to see the changes that you’re performing with your invoice before saving them. You'll see these changes take place in real-time on the sample invoice shown. You can also click Print Invoice Sample to see a larger preview of your invoice and to actually print off the sample to see whether it looks good on paper.
Are invoices translated into other languages?
There’s a number of special text label variables, which are responsible for changing the language of general invoice headings, like "order", "buyer", "phone", depending on the customer’s browser language.
This is the list of text label variables and their default English wordings:
| Variable | Text |
| ${textLabels.order} | Order |
| ${textLabels.orderComments} | Order comments |
| ${textLabels.footerMessage} | Thank you for your order! |
| ${textLabels.customerService} | Customer service |
| ${textLabels.phone} | Phone |
| ${textLabels.shippingMethod} | Shipping method |
| ${textLabels.paymentMethod} | Payment method |
| ${textLabels.discountCoupon} | Discount coupon |
| ${textLabels.items} | Items |
| ${textLabels.shipping} | Shipping |
| ${textLabels.total} | Total |
| ${textLabels.shipTo} | Ship to |
| ${textLabels.buyer} | Buyer |
Note, that these variables are automatically translated to another language if a translated label already exists in the Online Store, and the customer is using this language in their browser. Otherwise, the label will show up in English.
The rest content is retrieved from the order details and is displayed as recorded in the order.
How to change the text if it’s not translated yet?
You can check, whether the label is translated to your language in Ecwid Translate Service. If the label hasn’t been translated yet, as a temporary workaround, you can just replace the default variable with the preferable wording, and it will be displayed in the invoice as is, no matter what browser language the customer is using.
This way will also work if you want to change the default variant to your own text. For example, you can change the default footer message from "Thank you for your order!" to "Thank you for choosing us!": just replace the variable ${textLabels.footerMessage} with the wording "Thank you for choosing us!" in the template. 
Useful apps
You can also edit invoices with the help of the following paid apps from the Ecwid App Market:
Printout Designer
Printout Designer allows you to use a pre-made template for invoices (as well as for packing slips and shipping labels) or to create your own template that will fit your business needs.
You can also filter your orders by status or date when they’ve been placed, select all found orders and batch print invoices for them. Besides you can email invoices or download them in the form of PDF. You will be able to see the information about whether the order has been printed/shipped/e-mailed from the icons next to each order.
One Printout account can be used only with one Ecwid store.
PrintFantastic
PrintFantastic app allows you to create great-looking invoices as well as sales receipts, gift receipts, and packing lists.
The actual layout of each print cannot be changed. However, captions and messages can be edited and set to different language defaults. Also, items can be shown or hidden.
The Invoice Logo, Order Number, and Company Address cannot be changed since these are retrieved from your store.
Freshbooks Integration
Freshbooks Integration allows you to send new orders from your Ecwid store to Freshbooks accounting application.
The latter will create invoices with your company logo and other order details and, if you choose this option, email invoices to customers who just ordered.
From each new order sent by Ecwid, the app will also create customers in Freshbooks and, if the customer exists, it will assign respective orders to this customer.
