Invoice & Quotation Creation is an application that helps online shop owners, small stores, and freelancers create sales documents, quotes, and track receivables right on their phones. The application helps reduce the fragmented note-taking when advising, closing orders, and monitoring amounts that customers have paid.

Main features:

• Create quotes, orders, and sales invoices; convert quotes into invoices.
• Track receivables by invoice, record payment instances, and save customer history.
• Add VietQR transfer codes on documents; the Pro version supports pre-filling the amount and document code.
• Enter product names using Vietnamese voice on the Android version.
• Store business data locally on the device.

The application is designed for business habits in Vietnam, combining documents, receivables, and VietQR into one mobile tool. The generated documents are for internal management, not electronic invoices with tax codes.

To get started, visit the product page and select Google Play for Android or App Store for iPhone/iPad, then install the application. On iOS, the application is named Invoice & Quotation Creation; some features and services may differ between the two platforms.
