Virtual cards are debit card numbers that can be issued to OSC's hosted initiatives for paying online for things like: recurring payments, online resources/tools, subscriptions, etc. They are directly tied to collectives' budget on the Open Collective platform.

How it works:

Funds are spent only as transactions occur. (Setting up a card does not remove any money from your initiative's budget.)
Submit a virtual card request with the intended use of the card (please specify the names of the services you will use) and the amount budgeted for that use monthly (e.g. $300/monthly). We will review your request and reply with any questions.
If your collective needs a higher limit on your virtual card please request a limit increase by contacting us at hello@oscollective.org with the intended use and the amount increase needed.
To receive an increase, the project must have a budget on their Open Collective account that exceeds the corresponding amount and must demonstrate that a higher limit is necessary.
Cards must be used in compliance with our policy below.

Requirements/Policy:

These are virtual cards. No physical card will be issued, so these cannot be used in-store.
All transactions should comply with normal usage of initiative funds as outlined in our Terms of Fiscal Sponsorship
If a card has not been used for more than 15 months, the card will be frozen
If no receipt has been uploaded to an expense after 30 days, the card will be frozen
Admins are personally liable for misuse
The assigned card admin must complete a W-9 (for US-based admins) or a W-8BEN (for non-US admins) tax form before approval.

Limitations:

Virtual cards may not be used for paying/reimbursing people, that should be done on the OC platform.

If you need to input Cardholder contact details/address:

Name: Open Source Collective
Address: 440 N Barranca Ave #3939 Covina, CA 91723, USA

Steps to set up the card that need to be performed by the collective admin:

Log in to the Open Collective platform. In the left navigation, click on Virtual Cards -> Request a Card
OSC will assign the card (please allow time for processing)
Once assigned, the card assignee will be notified via email and the card's details will appear in the initiative's Settings for you to use (in accordance with this policy)

After a purchase is made:

The funds will be withdrawn from your initiative

An "Invitation to submit an expense" will be sent to your initiative admins
Admins will be asked to submit your receipt
If the receipt is not submitted within 30 days, the card access will be paused until you do submit the receipt
