Non-PRO French to English Bus/Financial Accounting Public Finances

Context of this translation (Transparency in Public Finances) and more especially the context relates to the procedure for PAYMENTS ON EXTERNAL RESOURCES (which I assume means payments made by means of external funding).

Here is the passage:

Description de la procédure de paiement sur ressources extérieures
Données issues des rencontres avec le MEF
La saisie de la demande de tirage de fonds est faite par le chef de projet au niveau de SIADE et transmise aux bailleurs de fonds, qui aboutira aux transferts de fonds, soit au compte spécial ou par paiement direct du fournisseur.

At the risk of exposing my very great ignorance in this area, I would really appreciate, once again your input and/or explanations on this passage.

I have translated the passage as follows: Description of payment on external resources procedure.
The draw-down request entered by the Project Manager via SIADE and forwarded to the donors, which will result in a transfer of funds, either to the Special Account or via a direct payment
*BY* the provider or should it be *TO* the provider

Another words, are they referring a payment made BY a 'provider of funds', ie the donor or to a payment made TO A SUPPLER?

I am not sure of what is meant in this context. I hope I have provided sufficient context.
