Also, you can select pre-defined line items from the dropdown. To add predefined items, just go to Sliced Invoices -> General Settings and add them in Quantity | Title | Price | Description format.

Invoice Details

Here you can add important things like client details, invoice number, date, currency and more. Most of the details will be filled in if you have configured the settings properly.

To create a new client, click on Add New Client. This will open a pop-up window:

Terms & Conditions

If you have already added the terms & conditions in Invoice Settings section, it will automatically show up here. You can also modify it if you want.

Once you have filled up all the required fields, click on Publish and make the invoice live:

Extensions

Sliced Invoices comes with free and paid extensions using which you can increase the functionality of your invoicing system and take it to the next level. Let me discuss some of them.

PDF Invoice Extension

PDF Invoice extension allows you to add a print button to the invoices and quotes in the admin area as well as on the front end. Thus, your clients will have the option to print or download the PDF invoices and quotes.

Client Area Extension

This extension creates a secure dashboard for your clients. Once they log in, they will be able to see all the invoices and quotes in a table format. They will have the option to export the table in CSV format or download the table in PDF format.

Not only that, they can also edit their business details like address, email, phone number and more.

Deposit Invoices Extension

Suppose you are working on a big project and want to take advance payment before starting the work. In that case, deposit invoices extension comes in handy.

After you have installed & activated this extension, go to an existing invoice, click on Deposit Invoice button and a new pop-up window will open up:
