Expense policies

We process payouts twice a week after they have been approved by the admin of the Collective. We make payments via PayPal and Bank Transfer (using Wise), and can only make payouts to countries served by these payment processors. You are not required to upload an invoice document (the data you submit in the expense form is sufficient) but if you would like to include an uploaded invoice, please make it out to: Collective Name, Open Source Collective, 440 N. Barranca Avenue #3717, Covina, CA 91723, USA

Here are examples of what a Reimbursement or Invoice needs to contain in order for us to process it for payment. 

If you would like a refund, email [email protected] with the # of the transaction, the collective you made the donation to, the date and the amount of the transaction.


Expenses need to be pre-approved using the same process we use for approving changes to the standard. See:

Guidelines for expense limits:

  • $700 for each one-time expense (e.g. a bug/feature bounty)
  • $100 / month recurring expense (e.g. pay for hosting or build machines)

We do not yet cover stipends for contributors

You can pre-approve an expense by creating a Discourse thread:

… answering the following questions:

  • What purpose is the expense for?
  • Is this a one-time or recurring expense?
  • What is the amount that you wish to expense?

Don't be afraid to ask! We'll do our best to work something out


How do I get paid from a Collective?
Submit an expense and provide your payment information.
How are expenses approved?
Collective admins are notified when an expense is submitted, and they can approve or reject it.
Is my private data made public?
No. Only the expense amount and description are public. Attachments, payment info, emails and addresses are only visible to you and the admins.
When will I get paid?
Payments are processed by the Collective's Fiscal Host, the organization that hold funds on their behalf. Many Fiscal Hosts pay expenses weekly, but each one is different.
Why do you need my legal name?
The display name is public and the legal name is private, appearing on receipts, invoices, and other official documentation used for tax and accounting purposes.
