Freelance, for anyone.

Once the app is downloaded on your phone, open it and create a Callmart listing for your freelance job. As an example, your listing can be a line of communication for your current clients to contact you, or to provide advice as a freelance job for people who want to become instrumentation engineers. It's all up to your own decision!

The photo for your listing can be what makes someone decide if they want to click on your listing or not, so make sure it's of great quality and is appropriate to the contents of your listing. Furthermore, keep both your title and description to a minimum length, but make sure to include an adequate amount of the key points to your listing.

Modifying the cost per minute of your listing can always be done after listing creation, so if you're unsure, pick a cost for your listing and observe how many people reach out to you. Based on your observations, make appropriate changes to your cost per minute and you'll eventually find the perfect cost for your service!

Value for Instrumentation Engineers

The great thing is that instrumentation engineers don't have to do much to market their freelance listing; Callmart's share URL option does it all. This option gives your listing a unique URL that can be shared anywhere in seconds. Use this to promote your listing on sites like Facebook and LinkedIn, and also any company site that your clients frequently use.

International communication and knowledge exchange is what we aim for. Callmart is available in 6 different languages - English, Korean, German, French, Spanish and Japanese. Additionally, transactions on our app are available for 135 currencies!

The moment you hang up the phone with a buyer, you get paid on the app! Callmart automatically charges each minute of every call, so that you don't have to do any work in collecting your hard-earned money from people you've provided a service to!

The Optimal Freelance Job

The global market gives instrumentation engineers a truly one-of-a-kind experience to earn money with a freelance job created by themselves. You can also hide a listing from the marketplace by toggling your settings to private - that way, you can communicate with only the people you want to provide a service to.

There's a fee of 3% that Callmart charges for every call, which is used to keep our service going and to improve it as much as we possibly can. Stripe is an online payment processing provider that we use for the app, and they charge a small fee as well.

Capitalize on all the free time you have by using Callmart. It doesn't matter whether you've got an hour or only a minute of free time; using our app will earn you money in any case! Just talk on the phone, get paid, transfer your earnings to your bank account and then you're done!

Callmart is a global C2C marketplace app that connects instrumentation engineers with client through charged phone communications.
