Sling - Simple Laravel Invoice Generator.
It's an open-source web application that helps you create invoices and track income. Sling is based on the Laravel PHP framework.


Sling was originally created for personal use, for convenient accounting of income and invoice generation for Individual Entrepreneur with "Small Business" status in Georgia (tax is paid on total revenue every month). This application will be useful for businesses and individuals with a similar taxation system, or just for generating invoices and income accounting.


  • Client Accounting.
  • Separate invoice number prefix for each customer with the ability to set the initial number index.
  • Generate invoices & Download invoices as PDF.
  • Invoicing model: "one invoice = one service"
  • One main currency for accounting with the ability to invoice in other currencies. If the invoice is billed in a non-primary currency, it is possible to get an exchange rate from an exchange rate provider for the invoice payment date. At the moment only exchange rate provider for GEL (Georgian Lari) is available, but providers for other currencies can be easily added.
  • Unlimited number of payment methods can be created. Different payment method can be selected for each invoice. Information about the selected payment method will be added to the generated invoice.
  • Reports generation for the selected period with grouping by clients


Footer for a picture or photo with ImageMagick

Snippets 20:09 / 05.07.2021

Recently in one of the chats a task on ImageMagick was discussed, which I found interesting, due to the fact that it was considered to be difficult and there were no ready similar solutions.

Briefly, the task was as follows: you need to write a script that will use ImageMagick to add a footer to a photo or image. And this footer should not overlap the original image, but be added at the bottom by the width of the processed image. The footer (black) should have a logo (static) and two labels (white) with the ability to choose any fonts for these labels.

I've never had any experience with ImageMagick for PHP before, as for my tasks I was satisfied with the capabilities of GD library. I wanted to solve this task, and with the ready solution I'm sharing in this publication.
