Sign.cc by 500apps allows you to sign your agreements and other documents, and another to be able to do so faster and more effectively. With advanced reports, it helps boost your revenue by visualizing how many documents were completed, pending, or declined. You can keep your documents in order and manage them as needed with the bulk, tag, and status options. Here are the top five features individually in detail: 1. Signature Maker Many agreements and contracts communicated and signed today are graphic documents as well as text-based documents. In this case, the Signature Maker function, as well as an upload facility for signatories to add their signature, is critical. Senders and signatories will be able to simply draw their signatures on papers, which may then be downloaded or stored for future signing. 2. Customization The option to add your company's logo to the sealed cover of papers being sent acts as a kind of assurance that the documents are genuine and being sent from you, rather than a scammer or someone attempting to steal personal information. This leads to faster document turnaround, more exposure, awareness, and increased trust between you and the signatories. It might be as basic as your company's logo, brand design, and color scheme. 3. Security In electronic signature software, this is a critical characteristic to check for. SSL encryption is a must-have since it protects your documents' contents while they're being transferred between you and your signatories and prevents outsiders from accessing your confidential business information. SSL stands for Secure Socket Layer, and it is a technique that protects your internet connection from eavesdropping. Each document you provide for signature should be able to be encrypted and password-protected using your software. 4. Multiple Platform Capabilities Because you never know what sort of device your signatories are using, it's critical that your electronic signature software supports a wide range of platforms and devices, including Androids, PCs, Apple devices, Tablets, and so on. This might mean that your program has a website and a mobile app that can be downloaded on all of these devices, as well as others. This will make the signing and submitting procedure easier and faster. 5. Templates When you have pre-designed templates in your e-signature software, you won't have to start drafting contracts from scratch when you need something quickly. You may quickly find a template that meets your needs, fill in the necessary information, and have your agreement created and ready to send to your signatories in minutes. You may also make changes to existing documents by uploading them, adding fields from your templates, and eliminating fields you don't need. This shortens the time it takes to create and execute an agreement.
