This invoicing system has exceeded my expectations, from estimates to invoices. I can do everything from my phone, data is secure on the app. Technical team is super efficient when you email or whatsapp them with any issues or even just for information about the app. I am in South Africa. Definitely recommend.

Thanks to the Invoice Manager team for creating such a useful and easy-to-use app. It helps a lot in managing invoices smoothly. I have two small suggestions: Please add an option to create profit-based categories, such as assigning items with 5% or 10% profit to different categories or persons. Please allow copyable invoice data sharing via WhatsApp or mobile numbers instead of only images or PDFs. Overall, it’s a great app. Keep up the good work!
