Users can be added to the Z.comSign system without limitation according to the company's structure. Even without registration on the system, anyone can be the signer for signing requests but only registered users can request or access to all the signed documents.

It's recommended that all employees in a company be registered as users and utilize the "User Access Control" feature to limit the access of users based on their roles and department in the organization.

Documents can be stored on the Z.comSign system without limitation of data storage space. Unlike some of the signing solutions or document management system available in the market, all signed documents on Z.comSign will have no expiration period and be kept forever on our system until the account is terminated.

Z.comSign has is accessible via web-interface or smartphone application on iOS/Android.

Users will be able to monitor and track the status of document signing after sending out an signing request. This can effectively increase the productivity of any kind of approval process in a company because the requester can know whether the sign is complete or rejected anytime even if the signing request is sent to other external companies.

Users can upload documents in PDF/Mircosoft Words or create documents using the templates on the management page. Usually documents are uploaded everytime to be sent out for signing request, but on Z.comSign, we have a feature to allow requester to prepare different signer name and other information on CSV file and use that information to generate multiple signing request at one time.

*Example: An admin manager can prepare a list of staffs' name on CSV and use Z.comSign to automatically generate 100 salary payment acknowledgement letter with different staff name to be sent out to all staffs at one click.

For all documents signed, the system will generate multiple files to be provided to all signers to keep as reference. Even if the signer is not a registered user on Z.comSign sytem, the cloned document will be available for the signer to download from the system via email notification. This is very efficient to avoid the process of file copying and process to share the signed document to all related personnel again after the signing process is finished, which is one of the main redundant work if its a signing process on paper.

This feature can be used to define users into different groups and different roles to be registered on the system. (ex. to split users based on the department of a company)

By doing this, admin user can restrict accessibility of users to view documents of different department for compliance purpose and define who in that department can the permission to request for signing, to be the signer or even just an user that can only open files without authorization of document management.

IP filter can be used to restrict the accessibility from pre-defined origin IP addresses of the user to increase the IT security level of the account.

*This technology is being used by Netflix, Youtube, or even other online services too to enforce privacy to the media contents uploaded to the internet but requires access restriction to certain personal or group of users.

(ex. Company can set the IP filter to allow only access from static IP address of the company office or VPN server to avoid access from random IP addresses.)

**Available only for Pro-Plan and Enterprise-Plan.

Workflow templates can be used to pre-define the Line of Approvers into the templates so that users do not need to select signers everytime for frequent approval transactions.

(ex. Sales department of a company can set a template to request for signing process for quotation approval to manager of the department)

**Available only for Pro-Plan and Enterprise-Plan.

User management via CSV file can be used to manage users in a more efficient way, especially for companies that has many users with frequent changes of user entry.

(ex. If a company has 1000 staffs that needs to be newly registered on the system, admin user can prepare a CSV file with a list of users and update the database via the information on the file.)

**Available only for Pro-Plan and Enterprise-Plan.
