+## Claiming a bounty
+
+Once a bounty has been fully finalized, you can request your payment by _submitting an expense_ via [Open Collective](https://opencollective.com/comunica-association/).
+When submitting an expense, you must attach an invoice, which must be a valid fiscal document.
+This document must at least contain a VAT ID and your address and the Comunica Association's address:
+
+```
+Comunica Association
+Cantorsteen 10  
+1000 Bruxelles  
+België
+```
+
+All expenses are handled by [Open Collective Europe](https://docs.opencollective.com/oceurope).
+More details on expenses can be found on [Open Collective Europe's wiki](https://docs.opencollective.com/oceurope/how-it-works/expenses).

 ## Rules
 
 1. While anyone is allowed to take up bounties, if board members want to take up bounties, all other board members have to agree, to avoid conflicts of interest.
