+## Getting Paid Out
+
+After a succesful project, a pull request to [https://github.com/SciML/sciml.ai](https://github.com/SciML/sciml.ai)
+must be made that updates the Small Grants project page declaring the project as completed
+by moving it to the completed section. This pull request then must be merged by the designed
+reviewer. Once this is merged, the project is declared to be successfully completed unless
+comments by the reviewer in the pull request suggest otherwise. Upon completion, open an
+expense report at [https://opencollective.com/sciml/expenses/new](https://opencollective.com/sciml/expenses/new)
+and follow the instructions to submit an expense. In the expense report,
+
+We need a PDF invoice on file. Please submit an invoice using an invoice template (for example: https://create.microsoft.com/en-us/templates/invoices) that contains the following information:
+
+* Current Date
+* Unique Invoice Number
+* Name and Contact Information
+* Bill To Information (NumFOCUS)
+* Project Name and Grant Information (if relevant)
+* Period of Work Performed
+* Itemized List of Work Performed
+* Short description
+* Hourly rate
+* Total for Invoice
+* Payment Terms (e.g., Net 30)
+
+Lastly, in order to process payment, we the following should be added as a comment to the report filing:
+
+* SWIFT/BIC#
+* IFSC
+* Account Number
+
+A steering council member will review that the expense matches the approved grant and, if so, approve
+the expense. This finalizes the process and the payment will be sent.
