General

What is the difference between free and paid service?

With licensed projects and other paid plans, the main differences are:

increased resource quotas
better quality of hosting
prioritized support.

We encourage you to make an account and explore our product for free. Other than lack of internet access for free projects, there is no difference in functionality between the free and for-pay versions of CoCalc. Everything is private by default for free users. You can make as many projects as you want. You can start teaching a course in CoCalc for free, then add a license later so that your students have a much better quality experience (for a small fraction of the cost of their textbook).

How do I get an invoice with specific information?

After purchasing, please email us at help@cocalc.com, reference what you bought, and tell us the payer’s name, contact information and any other specific instructions. We will then respond with a custom invoice for your purchase that satisfies your unique requirements.

Can I pay via wire transfer?

For purchases above $100 we support wire transfers. Please contact help@cocalc.com with all relevant details about your intended purchase.

The free servers really are massively overloaded, so it is well worth it to upgrade to member hosting, enable internet access, etc.

In case you’re teaching a course and bought a license to manage that course: please read 2. Install your license(s) in the course file..
