Square

Most businesses are familiar with Square as the SMB payment processing solution. But now, the word is now associated with another quick and simple commercial process: invoicing.

This invoicing tool allows you to generate professional digital bills instantaneously, issue email or text receipts, measure company performance, and get paid faster. You can send out digital invoices (and estimates) in seconds using Square invoicing. And you may monitor those payments using the web dashboard from any device. Square also allows businesses of all sizes to send reminders and take payments online using a variety of easy payment methods, such as Apple Pay and Google Pay. Square allows you to keep your frequent clients' business cards for auto-billing. Square also goes a step further by allowing you to effectively manage your cash flow with comprehensive reporting, progress invoicing, and other features.
