About Billy
From the official readme · v2.6.1Description
This plugin helps you to speed up your billing process, from creating invoices and quotes, minimizing any potential errors to getting paid faster.
Electronic invoices, quotes and accounting records can be set up in just a matter of minutes. Invoice numbers are generated automatically in unique and sequential order. For convenience reasons the totals of the table rows are calculated in What You See Is What You Get real-time.
Global settings like your name, your address, the invoice number format, tax rates and the currency can be defined in the Customizer.
The header can be branded with your logo. Any frontend styles will be inherited from the theme, so please make sure the theme installed on your site fully supports the block editor.

Target group?
- Freelancers and small agencies that need a billing suite which integrates seamlessly into their existing WordPress environment.
Compatible themes?
The plugin should work with any modern WordPress theme that supports the Block editor. Minor style modifications in the theme may be required.
Heads up: Please note that the main content area of the Single/Custom Post Template of your theme needs to be setup in “fullwidth” format. Having a sidebar may narrow the (invoice) table layout too much.

Frequently asked questions
Where can I find the developer documentation?
Demos and docs can be found here: https://them.es/plugins/billy
Are there any recommended third-party plugins?
Since you’re using a self hosted version for your billing data, installing a WordPress Backup Plugin should be mandatory. Furthermore Exporting your Customizer options is highly recommended since Customizer values may get lost when switching your theme.
I’m not sure where to begin!
Head over to https://them.es/plugins/billy/docs/ to view the official documentation, which should help you get started.
Where can I get help?
You can ask questions or post feature requests in the Support forums https://wordpress.org/support/plugin/billy https://them.es/support
The Billy templates don’t look good in my theme
Please note that we can’t support you in getting individual themes customized. But if your theme supports the Block editor everything should work out of the box. Minor CSS changes may be required. The plugin has been tested with the latest default WordPress themes and with some other major themes.
How can I style the Billy templates?
Billy uses core Gutenberg block styles – so your theme needs to support Gutenberg blocks. All Billy templates are inheriting the styles of your theme. If required you can edit the style.css file of your theme or add custom CSS in the Customizer.
How do I create a PDF version of my invoices/quotes?
A PDF-Exporter is included. If you need an exact copy of the screen version you can try the Print to PDF feature built into your operating system.
How do I create an UBL e-invoice?
This is only possible in the PRO add-on and considered “beta” support. You can generate a XML that can be sent to third-parties for further processing.
Why do I see a 404 error page when trying to open an invoice/quote?
Billing information is sensitive data! Due to privacy reasons these posts cannot be made public which means that only authorized users have access. You need to be logged in to see private posts. If you would like to share a post with others you need to use the Share Link option in the PRO add-on.
I need more features!
