The government of Nigeria buys products and services through a "tenders board" composed of senior government officials, and may include local consultants or foreign firms with representatives in Nigeria. The Central Bank of Nigeria (CBN) does not buy products and services for the Nigerian government or its agencies. Email and fax inquiries and business proposals purportedly emanating from the CBN on behalf of the Nigerian government or any of its agencies should be disregarded. The CBN has been used and mentioned in several cases of financial and related crimes. The Central Bank warns foreign firms interested in doing business in Nigeria to be wary of business proposals and private offers that seem too good to be true.

In an effort to fight official corruption and to introduce probity and accountability into the government procurement process, Government of Nigeria established an agency known as Budget Monitoring and Price Intelligence Unit, a.k.a. Due Process to evaluate contracts and tenders, and to ensure strict compliance with civil service procedure. The monitoring unit is under the presidency and reports directly to the president. According to official reports, the unit has saved Nigeria millions of dollars in contract fees and payments associated with government tenders. Inflation of contract values by government officials continues to be one of Nigeria’s most difficult corrupt business practices. Culprits are supposed to be arrested and prosecuted by the Economic and Financial Crime Commission (EFCC), but the agency continues to receive mixed reviews of its success.
