Expense policies
File an invoice only when you are requesting payment for services you personally performed. We can only pay the individual who completed the work -- no third parties or friends. The person who performed the work must be the owner of the account receiving payment.
We have strict requirements for what we can and cannot process. Certain information is required on all invoices, and we cannot process payment if required information is missing.
Please review our full policies before submitting:

If your expense is missing required information or documentation, you will be asked to revise it before processing can begin.
Processing and Payment:
- Expenses are processed twice weekly after approval by a Collective administrator and a secondary OSC review
- Payments are made via PayPal or Wise (bank transfer)
- Payments are limited to countries supported by these providers
- If you use PayPal, you may be required to complete a KYC process
An uploaded invoice is not required -- the information entered in the expense form is sufficient.
If you choose to upload an invoice, address it to:
Collective/Project Name, Open Source Collective
440 N. Barranca Avenue #3939
Covina, CA 91723, USA
Anyone can file an expense, but should agree this with the Testcontainers core team before incurring any costs. If the expense makes sense for the development of the community, it will be “merged” in the ledger of our open collective by the Testcontainers core team and the person who filed the expense will be reimbursed.
Money will first be used to cover direct project costs:
- Bug bounties
- Website hosting
- Tooling, such as CI infrastructure
- Legal protection
Then, money will be used to:
- Pay for project expenses (e.g. ‘swag’, stickers, T-shirts, etc).
- Pay expenses for core maintainers’ travel to present at conferences and meetups, if not reimbursable by the conference/meetup or employers.
- Pay expenses for developer gatherings: travel expenses for core maintainer meetings
- Pay core maintainers for time expended on key project engineering activities, e.g. release engineering, project housekeeping, expedited PR review for bug-bountied tickets.
Who can approve expenses (the ‘Testcontainers core team’)?
This list is likely to change over time, but is currently Richard North, Sergei Egorov and Kevin Wittek.
