Step 1

A Flexible Life with Callmart.

To begin, start your journey to make money and create a Callmart listing for your flexible job. As a computer science student, you probably have a lot of knowledge that can be useful to students all over the world, so this can be a good foundation to your listing on Callmart!

Due to the sheer amount of sellers on the marketplace, push the odds in your favor by taking time with making your title and description as short but informative as possible. For your description, you can do this by using bullet points, or a short summary of the important points of your service. Top it all off by including a photo that is of high quality (i.e. unpixelated).

Adjusting your fee per minute is always doable even after you've created your listing, so test the waters out! Start with one price, gauge the amount of calls you actually receive as opposed to your expectations, and then adjust your price based on that.

Step 2

Merits for Computer Science Students

Callmart makes it really easy for computer science students to raise awareness for their listing. Once you've created your listing, use Callmart's share listing feature - this will display a special, shareable URL that you can share on popular sites like Twitter with just a single tap on the app. Since you're a student, be flexible with sharing your URL!

Callmart lets you handle your transactions with 135 currencies of the world, and the app is available in 6 languages - English, French German, Japanese, Korean and Spanish. Are you ready to share your knowledge with the world? You might even learn something new in the process, too!

As soon as a call ends between you and your buyer, you get paid on the app immediately without any risk of non-payments. Callmart automatically charges every call in one minute increments, so that you don't have to worry about getting paid for providing a service for your listing!

Step 3

First-Class Flexibility

A marketplace where you can start your own flexible job and grow your own skills is what Callmart provides to all computer science students. For situations where you'd rather your listing be off the marketplace, just edit your listing and switch it from 'public' to 'private'.

Please be aware of our service fee (3%). We charge this fee in order to help us keep our products and services continuously updated. Please also know that our third party payment processing service provider, Stripe, also charges a small fee in order to maintain the integrity of the payment system.

If you’ve got some free time, why not turn it into cash? Whether at home, at work, at school or in your car, you can use the app to start making extra money.
