FlyTax

FlyTax will allow you to quickly issue an invoice and send it to the contractor. It is a very simple tool designed primarily for sole proprietorships.
Registration is very simple - it requires providing basic login details and your company details necessary to issue and accept invoices. For your safety, it is also required to provide a verification code sent to your email address provided during registration. After your first login, you stay logged in all the time.
You configure the data of your customers, products and your company in the settings module or when issuing an invoice - once you enter the customer or product into the system and in the next document you only need to indicate it.
After issuing the invoice, you can send it to the customer by e-mail as a PDF attachment or download and store it on your device. You decide whether you want to receive a copy to your email address.
In addition to revenue invoices, you can add cost invoices issued by your suppliers. You can easily mark whether an invoice has already been paid by you and don't worry about it anymore.
You can find a summary of your expenses and income on the Dashboard - the default tab of your application.
