Ask HN: partnership agreements in the Middle East and payment processing

We are in the process of setting up our company (with a newly-developed enterprise SaaS product). We have started negotiations with potential partners in our primary market, the Middle East (Qatar, UAE, KSA). As far we understand, all the partnership agreements in those countries dictates the formation of a new entity where we'd be a minor shareholder. All payments would be flown through through the new company. From the technical side, as we are now preparing to setup the payment processing (for our corporate Canadian entity), how could we merge the two; The payment processing (Canadian corporation) and the new middle-east company. One further complication is that a new partnership agreement (and  new entity) needs to be established for each country we want to introduce the product in. Any prior experiences or pointers are appreciated.
