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

Billy is self-hosted and you can publish as many posts as 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.

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.

There are many possibilities to achieve this. You can create a Synced Pattern (Core’s 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 a post and modify it afterwards.

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 al the time. And no worries – if you try to close the browser tab you will be prompted with a notification alert so nothing will get lost.

In the end this does make sense. And did you know that you can see the actual duration in the tab title in realtime?

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

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

Child posts for to-do lists and time tracking projects are connected to a parent post.

One advantage is that you will have a better overview of all (sub) projects. Furthermore the sum of all connected time entries will be output in the main project.

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; }

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.

Please make sure that the directory /mpdf/tmp is writable by the server. This directory is needed for temporary storage of important PDF data.

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 it’s possible to fix this error and update the translations. Unfortunately you have to fiddle in the HTML Code Editor and not everyone is comfortable doing so.

If you’re uncertain, just leave it as is. The stored post content is not affected and you can still view the old invoices and download a PDF version.

Otherwise feel free to follow these steps:

1. Open the Code Editor view

2. Search in the content area for invoice-table

3. Lookup all translation strings like Description, Amount, etc. and replace them with the corresponding translation – you can create a new invoice post first and compare the values

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
