Niaje, Pricing ni one of the most vital decision utamake kwa biz yako juu ita affect your growth either negatively ama positively. Market research is important juu itakuhelp kujua how much your customers are willing to pay and how much your competitors are selling at.

Mi hutumia strategy inaitwa Cost-Plus pricing. Hapa you add up all the costs involved kuget hiyo product, then unaset profit margin. While doing your calculations don't forget to add your labour. Your time is valuable too.

Tuseme chupa moja ya maji unabuy at 20/= na a whole case has 30 pieces. Utauza a bottle at 40/= 10/= tuseme ni yako ya labour then 10/= ni ya transportation ya kuleta stock.

Profit yako per 30 pieces itakuwa 600/= Remember ulibuy at 600/= per case.

Here's a breakdown:

   *Buying price- 20/=
   *Labour- 10/=
   *Transportation- 10/=
~~~~~~~~~~~~~~~~~
   *Selling price- 40/=
40/= multiply by 30pieces
Total: 1200/=

Profit:
 *1200/= minus total buying price (600/=)

Total profit- 600/=

Same applies to books and everything you're selling.
Also, try and find the cheapest plugs for your products. This way, you can make adjustments to your selling price.

NB: DON'T PRICE OVER THE MARKET PRICE

All the best.
