Handling monthly collection of stock for consignment stock when 4 parties are involved

Question

Hello Team,
The Business case is:
The whole flow is for the Company (C) who uses Oracle core modules like Inv, PO, OM, etc. External Logistics partner (E) procures product from various Suppliers for the Company (C). The same is being informed to C by E - which is kind of consigned stock (can be fulfilled by PO receipt, where supplier is E  - the stock will be in On-hand of C where owning party is E).  The stock is now sent to C's one of the shop by E, based on external Order demand, a sales order issue can work which ideally will do transfer to regular of stock. E raises payable invoice to C and C collects receivables amount from end Customer.
The issue in requirement is where the flow goes little differently (banks comes into picture for financing the stock).
1) In many cases, the financing of stock will be done by Banks (B). E raises payable invoice to B (not C) as the stock is financed by Bank- documents maintained outside the system, B pays full money of stock to E and every month C collects EMI from end customer and pays back to B.
2) Other case related to above point- price of a product say AS54888 will be USD 100 which C wants to be sold to Customer under some promotion at say USD 80. E should get actual USD100 from Bank B, C should pay EMI to Bank every month say USD 10 (for 10 months) but it collects for 8 months (USD 10 *8) from Customer - the C takes a loss of USD 20 in this example.
Any clue to meet above requirement in core modules (we do not use Oracle BRM) will be appreciated. Thanks in anticipation.
B/R,
