Billy is a self-hosted plugin that gives you the freedom and flexibility to publish as many posts as you want and to use it wherever you want. Server resources and storage space are the only limit. As long as you are using a state-of-the art system this shouldn’t be an issue.

If your theme has (at least basic) support for the Block editor, Billy should work just fine out-of-the-box. In some settings it may be necessary to slightly customize stylesheets or post templates.

Minor style changes can be done via Appearance > Customize > Additional CSS.

For full flexibility with even complex modifications you can create a Child Theme.

In addition you can fully customize the layout by uploading block templates in your theme directory /templates/billy-{invoice|quote|accounting}.html or by adding add_filter(billy_{invoice|quote}_template) hooks. PDF templates can be customized in /templates/billy-{invoice|quote|accounting}-pdf-{content|footer}.html or by adding add_filter(billy_pdf_{content|footer}) hooks (see Customizations).

Yes you can. When setting up Billy initially you can start from a specific invoice number series by defining your current invoice number.

It is recommended to run both systems in parallel for a specific time until you feel confident with your new billing workflow.

Importing existing data like invoices, quotes and contacts would be possible as well but technical know-how of an experienced WordPress developer may be required to achieve this.

If supported by their bank, payers can use their e-banking app to scan the QR code on the invoice and pre-populate payment requests. This saves time and prevents typing errors.

The QR code markup may differ depending on your country and needs to be added manually in the Customizer settings.

We’ve created a tool that helps you generate the required EPC values. If your bank account doesn’t support the EPC payment system, you need to manually set up the markup with all parameters according to the guidelines of the payment scheme.

Afterwards you need to paste the generated code in the according Customizer setting.

Please don’t forget to test everything before you push it live and please understand that we can’t help you with setting up the QR code and that you’re using this service at your own risk. If in doubt, do not activate this setting!

There are many possibilities to achieve this. You can create a Synced Pattern (reusable block feature) by selecting the blocks in the table and clicking on Create pattern. Afterwards you can select it from the Block Inserter whenever needed.

If you feel comfortable and have development skills you can also setup shortcodes with the content block.

Another approach would be to install a post duplication plugin, create a 1:1 copy of an existing Billy post.

Unfortunately not. When closing the WordPress Editor any unsaved changes will get lost. So please make sure that the page stays open in a tab all the time. But no worries – if you try to close the browser tab you will be prompted with an alert that must be explicitly confirmed. So nothing will ever get lost.

Did you know that we’ve implemented a neat feature so that you can see the actual duration in the browser tab title in realtime?

Certainly. Just select the start and end time via the calendar input controls.

Time tracking entries that have been stopped can’t be started over again. But you can always add a new time entry row below and proceed. If you need to modify the dates subsequently, use the calendar input controls.

Child posts are connected to a parent post and show up indented in the posts overview. Ultimately, it can help you organize and keep track of all your (sub-)projects.

The calculated sum of all connected time entries will be output in the parent post.

Basic PDF styling is possible in the PRO version. Go to the Customizer and access Billy > PDF-Export. There you will find a field “CSS” where you can style the HTML elements.

E.g. Change the font-size and add a border to the tables:

body { font-size: 11pt; }
.wp-block-table tbody tr, .wp-block-table tbody tr td, .wp-block-table tbody tr th { border: 1pt solid; }
.wp-block-table tfoot tr td { border: 1pt solid; }

Please note that this is a PRO feature. Click on the “Send Email” button and use the webform to email the PDF (or PDF+UBL) version as attachment to your contact.

If needed you can add a CC or BCC email address or change the subject and the email body.

Pre-populated field values like subject and body can be defined in the Customizer.

Add your email address in the CC (or BCC) field of the webform to receive an exact copy of the email in your inbox.

Alternatively you could install an Email-log plugin.

Please make sure that the directory /mpdf/tmp is writable by the server. This directory is needed for temporary storage of internal PDF resources like images, fonts and stylesheets.

Please note that this is a PRO feature. UBL (Universal Business Language) is an open standard for electronic business documents like invoices based on the XML format. It’s mainly used in B2B settings and simplifies the automation of information exchange.

Providing a UBL version of electronic invoices may be required by law in your country.

UBL generation needs to be activated in the global settings. If enabled you will see a download link next to the PDF previews of your invoices.

Our integration of the UBL standard has been implemented with care and is handled by an Open Source library that already has many years of experience in this area. Furthermore we constantly test the generated markup using different third-party validators and adapt our data exporter, if needed.

Unfortunately the specifications of UBL are rather complex and there is no universal approach of getting it right because countries or authorities may have different regulations and custom requirements. That’s why it’s marked as “beta”.

All in all the generated data should still be helpful and you should be able to easily solve any issues by yourself.

Some contracting parties even provide a webform where you can upload the XML, test the structure and modify any missing data via a simple GUI. Ask for it.

Otherwise you have to manually check the XML output based on a provided template and edit the data in a text editor or similar tool.

Feedback on this feature and on our technical implementation is always welcome but please note that we can only accept bug reports here and, as stated above, may not consider specific requirements or edge cases that would set off a whole series of cases.

A Geocoder extracts data like street name, house number, postal code and city from an address string.

The information is processed in vCards and in e-invoices. In addition it helps to validate the provided address so that you can be sure it’s correct.

We integrated the privacy friendly and free Nominatim service (powered by OpenStreet Maps) and no registration or API key is required.

Unfortunately linking post translations with WPML is not supported at the moment due to technical interferences while saving the post meta data.

If you need to translate Billy [PRO] posts you could give Polylang a try. It’s free and really easy to setup.

Block validation: Expected text Beschreibung, saw Description. This error may occur if the WordPress system language has been changed, which usually never happens at all.

The good thing is that in general it’s possible to fix this error by manually updating the translation strings. Unfortunately you have to fiddle in the HTML Code Editor and not everyone is comfortable doing so.

If in doubt, just leave it as is. The stored post content is not affected and you can still view the posts in the frontend and even download a PDF version.

If you want to fix it, feel free to follow these steps:

1. Open the Code Editor view

2. Search in the content area for e.g. invoice-table

3. Lookup all translation strings like Description, Amount, etc. and replace them with the corresponding translation – you can see the correct strings in other invoice posts

4. When you’re done, close the Code Editor and review the table

5. If you still see an error, repeat steps 2 and 3 until it works

Do you see any error messages when activating the product?
Which CMS version is being used?
Which themes/plugins are activated. Do you have the latest versions installed?
Do you use a PHP version which is up-to-date and still supported?
Which operating system and browser version is being used?

Short answer: No.

Long answer: First of all, once you purchased an activation key you are permitted to install the plugin on your own WordPress instance(s).

Incorporating static third-party code in a theme is a bad idea because it prevents installing important (security) updates.

Automatic updates are limited to the number of possible installs according to the license plan you purchased. License keys must never be made public, shared with others or included within the code.

Please make sure that you successfully activated the plugin or theme by entering the activation key.
