Whether you work in retail or the service industry, construction or creative arts, setting up an intuitive way to handle invoices and payments can make a world of difference in growing your business. With these apps, transactions are simple and seamless to create an effortless experience for both you and your customers.

These apps simplify the process of making polished and professional invoices designed to suit your brand, so you can send off bills wherever you are, plus create quotes, track expenses, and even take payments. Some apps, like Invoice Simple, will alert you when an invoice is paid or when it’s past due.

Online shop or brick-and-mortar boutique? Either way, these apps have you covered. Handle sales from your phone, track your inventory, turn your phone into a barcode scanner, or set up an online store and manage orders, customer requests, and reviews on the go. In addition to taking payments, apps like Square and Shopify offer an at-a-glance view of your recent sales performance, so it’s easy to keep tabs on the health of your business.
