How to automate invoice generation in your online store
Running an online store involves much more than selling products. As order volume increases, so does the need to issue invoices, manage tax documents and ensure compliance with legal requirements.
For many businesses, manual invoicing represents a significant loss of time and increases the risk of administrative errors. The integration between ePages Now and the invoicExpress invoicing system was developed precisely to solve this challenge.
Through this connection, orders placed in your online store can be quickly converted into tax documents, reducing repetitive tasks and enabling more efficient business management.

Why is it important to automate invoicing in an online store?
A modern online store should automate as many administrative processes as possible.
When invoicing is done manually, situations such as the following are common:
- Repeated entry of customer data
- Errors in invoiced amounts
- Time lost issuing documents
- Increased administrative workload

By integrating the ecommerce platform with an invoicing system, these problems can be significantly reduced.
Automation allows order information to be reused when creating the invoice, avoiding duplicated work and increasing team productivity.

How to generate an invoice from an order
Invoices can be generated automatically when the status changes to "Paid" and sent to the customer.
If you have configured manual sending (in epages Now under "Settings > invoicExpress"), you can generate invoices manually in the respective order in ePages Now.
- Go to the invoicExpress tab
- Enter the invoice date. Please note that all following invoices can only be issued on the same date or a later date.
- Choose whether there is a VAT exemption
- Click "Create Invoice"

The system automatically uses the order data to create the corresponding tax document, reducing the time required to complete the process.
You will have access to the invoice through the link or in the "InvoicExpress" application
