Hung Q. Le is an independent developer known for Manta, a lightweight desktop invoicing application designed for freelancers and small businesses that need to issue professional-looking bills without subscribing to cloud services. Built with web technologies and packaged as a cross-platform desktop program, Manta focuses on giving users full control over invoice styling: it ships with a set of minimalist, modern templates that can be freely edited through an in-app drag-and-drop editor, and every color, font, logo placement or line item can be tweaked until the document matches the sender’s corporate identity. Beyond aesthetics, the software supports sequential numbering, multiple currencies, tax and discount calculation, client and product catalogs, and export to PDF, making it equally suitable for one-off project billing or recurring service invoices. Because data is stored locally in a transparent JSON format, accountants can back up or version the entire invoice history with ordinary file tools, while developers can extend functionality by forking the open-source repository. The workflow is intentionally narrow—no inventory, time-tracking or payment gateways—so that a user can open the app, pick a template, populate line items, and e-mail the finished PDF within minutes. Manta is available free of charge on get.nero.com, where the latest Windows build is delivered through trusted package sources such as winget, and it can be installed individually or batched alongside other applications without extra configuration.
