Invoicing Feature Requests

I would really love to see the option for Clients to use Klarna and Afterpay is possible and it to be toggled on an off per invoice/proposal/agreement. It is a huge thing I keep hearing people asking about and mentioning, and my current response is I can do in-house no interest payment plans - but yeah that doesn't always work with clients and not all of them want to do ach transactions.

Late Fees as a percentage are not the only way to do late fees - please allow late fee to be a set amount, ex: $50 instead of X% optional or able to be manually added. I can't be the only one who wants more direct control over adding a late fee to my clients invoices as opposed to just sticking them with it bc of an automated system To only apply after a certain number of days late. All my regular bills have a grace period, why shouldn't we offer that too?

starting in january 2025 all business owners have to provide their invoices in an electronic format (EN 16931 conform) along with the paper or pdf documents.

There are so many times clients come back with "I'd like to add this" or "Can I upgrade that?" but there's already a payment plan for the work. I'd love an easy way to add whatever the new service is to the invoice without having to make a note of it then, when the project is completed, finalize the payment plan and immediately have to go into the invoice, return to a draft, update with whatever the additional services are then resend. I have tons of notes all over the place, and I'm sure I'm forgetting to update people's invoices when we finally finish the project.

In Canada, we need to specify the amount of federal and provincial taxes separately (two different tax rates) in our invoices.

I would like to have a retainer for a client that I can use for multiple projects.

There are often times when I am invoicing for different categories of service and I want to be able to show that. It would be simple enough to just be able to add custom spacing or line dividers and/or headers as rich or markdown text if possible.

If any file is attached to the invoice, it doesn't get added as an attachment the invoice email. The only way to view it is by clicking on "view invoice online" and then downloading the file from there. Please add the option to add it to the invoice email as attachment.

Have the option when sending the invoice to have a copy sent to yourself.

I'd like to add attachments in the invoice email. I know they can be attached directly to the invoice but my client asked me to include it in the email.
