This paper presents a proper solution for a medium enterprise or public institution that enables easier management of the digital documents library and eases the common document workflows. The main problem addressed by the proposed project is the complexity of document workflows in public administration. Documents that need to be filled out and signed are always around us and often can cause problems and delays when poorly managed. With its characteristics, our solution eliminates all the inconvenient of the document workflows helped by the document library and workflows, while keeping the security part, now represented by hand signatures with the implementation of the digital signatures. The main benefit it brings to the client is that it automates the signing and approval process to any kind of document it uses inside or outside the company. The signature system allows signing on multiple levels (counter-signatures) and multiple signatures per level (co-signatures) for perfectly mimicking a plain document.
