About

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. Sling is based on the Laravel PHP framework.

Screenshots of the deployed app are available here.

Features

• 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.
