@ the Sage,
The directives on preferential treatment are rarely enforced (just like very many other clauses in the PPD Act. To be honest, it is unlikely that you'll given business on the basis of these "preference" clauses.
As I said in the earlier post, your best bet is to get involved in as many procurement processes as possible. As a target,make sure you are prequalified as a supplier in as many public bodies as possible (say at least 10). This is going to cost you some money (each entity may require anything between 2k and 5k for purchase of prequalification documents). My advise is avoid the bigger agencies for now (the KRAs, the KPAs, bigger ministries, etc). Target the smaller parastatals and smaller ministries (ERC, TARDA, KLB, ministry of Northern region, local authorities etc). There's less competition there and the bureaucracy is not that convoluted.
It is hard work and requires frequent follow ups and basically keeping your ear to the ground. And remember, government is the largest consumer everywhere in the world. If you are not doing business with the government, you are missing out on a sizeable chunk of the market.

General word of caution:

Government Business is not glamorous and neither is it for the fainthearted. One has to roll up their sleeves, visit government offices religiously, interact with procurement officers at a very personal level, meet with the same fellows after hours for a drink or two, be personable to them (there's a tendency of people looking down upon government workers) etc.
Govt not be hosted in posh and swanky offices but nothing beats the feeling of hearing these words: "kuja uchukue LPO yako".

@Wodu Wakiri, thank you for the insights. It is interesting that a relationship manager will use the expense account to court a client but will he/she treat the civil servant the same?
I too hope actually know that I will savor those words, "Kuja uchukue tender yako."
Better yet, "Kuja uchukue cheque yako."

At WW...my company just got registered...so wea do I start in this case. All I have is the certificate of incorporation/registration....

Anyone willing to discuss tendering in light of the new proposal to allocate 10% of all govt contracts to youth enterprises?
