Wave is a free online invoicing software that allows small businesses to create, send and track invoices, manage payments and expenses, and track sales and customers. It is specifically designed for freelancers, independent contractors and small businesses.
If you use Wave, you can connect your account to your GoodBarber app using Zapier*. You can then create automatic processes to manage your accounting in a fraction of the time: define your triggers (a new order in your store for example, or a new customer) and Zapier will order Wave to perform the actions you have planned (creation of invoices, creation of customers, creation of products or services...)
*You can also use the Make platform to connect your GoodBarber app to Wave.
