Step 1

Create a listing.

Mathematicians spend a lot of their time developing new rules, theories and concepts to solve practical problems in business and many other fields. Using your mathematical knowledge, you can make money by speaking to existing clients, students, and basically anyone using Callmart. Create a Callmart listing to get started.

When choosing a price per minute for your listing, you can either choose from one of the pre-existing prices on the drop-down menu, or come up with a custom price per minute of your own. You'll always have the option of changing your price per minute at any time, so don't worry too much about it.

Think of a title that best represents the service you're going to provide - there are a lot of listings on the marketplace, so you'll definitely want to stand out. When creating a description for your listing, keep the length to a minimum and make it easy to comprehend for anyone who takes a look at your listing!

Step 2

Share your listing.

Mathematicians can save a lot of time while simultaneously promoting their listing on the Internet by using Callmart's share URL feature. This will provide you with a URL unique to your listing, meaning that anyone that clicks on it will be sent straight to your Callmart listing without doing anything else. A huge timesaving feature that you should definitely make use of!

To start, share the unique URL of your listing on all the big social media platforms like Facebook, Twitter, Instagram and Reddit. All of this can be done in minutes with just a few taps on the app. If you want to keep your listing confidential, you can set it to private, then send your unique URL to the person you want to allow access to.

Making your listing public on the marketplace and sharing your unique URL across all social media platforms will help bring in more business from all around the world!

Step 3

Get Rich.

Calls on the app are charged automatically for each and every minute of a call, so you'll receive money instantly when your call has ended with a buyer! All the trouble and inconvenience with late payments are gone with Callmart.

To keep our platform running, we charge a 3% service fee for every call on the app. Additionally, Stripe, the third party online payment processing company we use, will also charge a small fee per transaction.

You can transfer the earnings you made on the app to your bank account whenever you please. Simply request a payout on the app and you're done!
