    User ID & Password: admin

    Application Rights


    One awesome feature in this web application is the application’s rights. But, what are these?

    Let’s say you have created any user or client. By default, when you add client it will also be added to application’s users. But client can not login unless the rights are specified in the application.

    So for example. You have a Operator whom you want to give access to the application where he can only see all the data but won’t be able to modify data or add new data. These are pretty much explained in the below steps.

    Add User Type
    • Login to your application.
    • Go to Tools > User Types.
    • Click on “Add New User Type”.
    • Specify name (e.g Operator) and click on Add.

    A new user type is successfully created in our application. We can add application users now to that type.

    Assign Application Rights to User Type

    Now as in the scenario discussed in Overview, let’s say we have a User Type “Operator” whom we want to give access to dashboard. This can be as follow.

    • Login to Application.
    • Go to Tools > User Types.
    • Next to your newly assigned User Type, click on Modify Page Rights.
    • Here a list will popup. Let’s just checkmark View Dashboard and Save Changes.

    Now, any user added to application with User Type “Operator” will be able to login and only see the dashboard of application but cannot see inner contents.

    Now, let’s give our User Type, Access to see the Dashboard Content.

    • Go to Tools > User Types.
    • Next to our newly created User Type, click on Modify Section Rights.
    • From here, select all the 5 boxes in first row and Save Changes.

    Now, Our User Type “Operator” will be able to View the Dashboard Content too.

    Repeat the same process for all other pages and sections to give perfect Rights to any User Type.

    For giving access to specific User Type for all other pages, explore the already defined Rights database for our Admin User Type in Tools > User Rights to find the one you need and Add Right access to specific User Type by above given steps.



    One more wonderful feature of this application is to change the color scheme of our application with few clicks.

    • Login to Application.
    • Go to Tools > Colors
    • By default, the 20 palettes are defined. Choose any one you like and click “Use this Color” and the color scheme of our application will be changed.

    Still not good enough? You can define your own color scheme for the application too in few simple steps.

    • Go to Tools > Colors
    • Click Add New Color
    • In Primary, type the primary color in HEX #000 or RGB rgb(255,255,0) format.
    • In Secondary, type the secondary color in same format.
    • Click Add.
    • Now choose the color you added and color scheme will be changed.

    The color scheme works for both the panel and the invoice designs. Separately select color sets to use on invoices and panel.


    Save all your clients details and data in the application. Use whenever needed.


    • Go to Clients > Add New
    • Fill the form with the client’s details and click Add.

    The data is managed and can be searched anytime. By default, when you add client. The Application User for that client will also be added but he won’t be able to login to the Application until the Rights are given to that User Type as described in Application Rights module of this documentation.


    No need of traditional Excel or Word documents to generate invoices which takes time. Time is money, save it. Generate invoices through the Application and send it to the clients instantly.  Save records of your earnings and know your yearly outcome.

    Add New Invoice

    • Go to Invoices > Add New.
    • Select or Add Client.
    • Select Due Date.
    • In Services Details section, Specify services you’re providing or description. Add as much as you want by clicking on Add Service button and generate the invoice.

    Set Invoice Template

    • Go to Tools > Company Profile.
    • Click on Edit Details
    • Next to the label “Template”, choose your desired template and save.

    Set Invoice Color

    • Go to Tools > Colors.
    • Choose the set from list and click on “Use as Invoice” button.
    View & Export Invoices as PDF
    • Go to Invoices.
    • Choose any Invoice and click on View to view the Invoice.
    • On top, click on Export PDF Button and the invoice is saved in PDF format to your PC.
    Email PDF Invoices

    Logs are all the records of the Application saved. Our Application will be saving all the actions made by any user in database and which we can easily access from our Admin Panel.

    • Go to Tools > Logs.
    • Here you can see all the logs performed in our Application with time and username.

    By default, Our application will be saving 2 types of logs.

    In Error Type Logs If any Error or a Crash in Application is made, a custom error page will be shown to the User while the original Error Details will be saved in the Logs.

    In Info Type Logs All the actions performed by any user regarding edit or creation of data will be saved as Info Type Logs.
