Turks prefer to do business with those they know and respect, therefore spend time establishing a personal relationship.
Relationships are fostered in the office, over extended lunches, dinners, and social outings.
Courtesy is crucial in all business dealings.
Turks do not require as much personal space as many other cultures and will stand close to you while conversing.
Do not back away, as this can be construed as unfriendly.
Discussions may start slowly, with many questions that may seem irrelevant to the purpose of your visit. It is extremely rude to insist that your colleagues get to the point.
Ask about his/her family without prying. Questions about children will be welcomed.
The Turks are proud of their country and will enjoy answering questions on their culture and history, although be sure to avoid political history.

Appointments are necessary and should be made 1 to 2 weeks in advance, preferably by telephone.
Many Turks take vacation during July or August, so it is best not to try to schedule appointments at that time.
It is also not a good idea to schedule meetings during Ramazan (Ramadan).
Punctuality is expected although you should be prepared to be kept waiting.
First appointments are more social- than business-oriented, since Turks prefer to do business with people they know. 
Small talk helps establish a rapport. Do not immediately begin discussing business. 
Have all printed material available in both English and Turkish.
Presentations should be well thought-out, thorough, and backed up with visual aids such as maps, chart and graphs.

Business is personal. Although this is changing with the influx of big multi-nationals and a more corporate culture in some of the larger companies, many businesses are still family owned and run.
Turks will want to do business with those they like, trust, feel comfortable with and with those that can provide a long term relationship. If they feel you are hiding something or there is an element of suspicion about your motives, you may not get very far.
Building a relationship with your Turkish counterpart(s) is therefore critical. The first meeting at least should be solely focused on getting to know each other. Once a relationship has been established you can safely move on to business matters.
As well as looking to the person, Turks are also astute business people. Ensure your proposal clearly demonstrates the mutual benefit and profitability of any agreement or partnership.
Turks are primarily oral and visual communicators, so in addition to written statistics, projections and the like try to present information vocally or with maps, graphs and charts.
Decision making can be slow. It is most likely, that you will meet and negotiate with less senior members of a family first. Once you are seen as trustworthy and your proposal financially viable, you will then move on to meet more senior members. A decision is ultimately made by the head of the family /company.
When negotiating, the Turks will start at extremes in order to gage your response. Prior to negotiations know your target figure and work slowly towards it through meaningful concessions. When conceding, ensure you present this as a favour and a decision made out of respect and liking for your counterpart(s). Try and concede only once you have gained agreement on a reciprocal concession on a separate or related issue.
