Hi @Anna3, I recently built a product around this feature, which lets you create invoices on the go while storing your client details to help you in assisting while creating future invoices. Just select a template and generate the invoice, you can even email the invoice to your customer. This product is not on webflow integrations yet, if you will be interested in such a product you can contact me on raghavmalawat@gmail.com and I can help you!
