«Procurement à la russe» — when you invite market suppliers to submit tenders and then realize that 2 of the 6 participants have the same sales team. Yes, they just work for both participants as freelancers at the same time, and ready to bid and fight with themselves during the negotiations stage. They also try to use «camouflage» to hide this aspect: different name spelling, different mobile phones and emails… I regret that I found out before meetings. Interested — are they ready to wear a fake mustache at the end? When I asked them about the efficiency of it, they answered — «always works on the local market.» Conclusion: Do as detailed a research as possible to make sure that you’re dealing with the right suppliers in a fair and transparent manner. Do you have some prior experiences?
