Whether you are a business owner or a freelancer, managing invoicing is a time consuming and tedious task. Every time you perform a service, the law requires you to send a complete and accurate invoice to your client. You can’t afford to do it every time manually on Word or Excel. Fortunately, there is software to do the work for you.

SAP software

Managing your invoices with SAP software allows you to optimize your accounting. This application allows you to link the whole of your company thanks to a centralized information system, where traditional management models are totally decentralized and do not allow to link the various trades. The problem with this is that the duplication of data in several departments increases the risk of error and the expenses related to data storage.
