It comes from the Togo Investment...

It comes from the Togo Investment Guide.

This is the relevant extract:

"Investment under the code is limited to new investments of at least FCFA25 million (about $42,000) for foreign companies and FCFA5 million (about $8,500) for Togolese companies. The Togolese corporation charter covers investments of less than FCFA five million. The investment code covers the expansions of existing enterprises if the cost of the expansion is at least half the value of the existing enterprise. Investors must provide at least 25 percent of the value of a new investment. At least 60 percent of the payroll must go to Togolese citizens.

Applications for approval under the law must be submitted to the planning ministry, which, in consultation with the national investment commission, approves or rejects the applications within 30 days, as compared to three to six months under the old law. In practice, approvals take slightly longer than the required 30 days. The Government decree granting approval spells out the conditions of the investment."

The above covers investments approvals but we don't know whether it covers a Tender process. It should but it's not 100% clear.
Luckily the 2nd last sentence gives us a bit of comfort:

"In practice, approvals take slightly longer than the required 30 days."
