[GRASS-PSC] Accounting and organization of sponsorship

[Moritz Lennert]

Dear all,

FYI, for our accounting I have created a continuous ledger in 
https://nextcloud.osgeo.org/ -> GRASS-PCS -> Accounting and have filled 
it with all transactions in our PayPal and bank account since 2018. The 
idea is to use this as our central accounting tool and note all coming 
transactions in this ledger. This will allow to easily extract annual 
accounts and follow our current financial situation.


As already discussed we should also review the way we collect 
sponsorship money, for different reasons:

- The current PayPal Money pool runs over my personal account which is 
not very bus-factor resilient.

- Venka's experience has shown that from some countries it is not easy 
to contribute without a PayPal account, e.g. with a credit card.

OSGeo uses a Github sponsorship system which we should advertise as 
people can dedicate their contribution to a specific project. However, 
AFAIU, the Github sponsorship system is limited to people with a Github 
account and only allows deciding on a continuous (monthly), not a 
one-shot donation.

In light of this, I would suggest the following for our sponsorship system:

- https://opencollective.com/ for flexible one-shot, credit-card based 
sponsorships, including a series of different options and advantages 
(ex: receipts) for sponsors. How we organize this exactly (via fiscal 
host) is still to be determined (maybe OSGeo can become a fiscal host 
for all OSGeo projects ?).

- https://github.com/sponsors/OSGeo for recurring sponsorship.

- Our bank account for direct money transfer, mostly within Europe.


Does this sound reasonable for everyone ? If yes, I will look into the 
details of Open Collective and create our system.
