Severe supply shortage

almost half of my corps in fb are not being fully supplied for many days now although i set buying strat at starting 150% , now its at 170%, is this not enough?

whats the solution? many corps are not making revenue at all because of no/small production and profits drop to the ground

Immediate order the products you need for a short term fix, then build corps that produce the products you need+contract them to the corps that need them. They will make a ton of profit if you can't get them at 170% price aswell.
