Ways to control your inventories

This article could be useful if you buy and sell goods. You want to have an adequate amount of stocks available for your customers, you do not want to buy goods that customers won't buy until they go obsolete and then you have to discard them. You could also want to have the lowest storage cost possible, thus not storing excessive goods which could then lead to a high storage cost. A lot of factors are taken into consideration, other factors include minimizing your cost of re-ordering goods annually. You do not want to tie up your capital in stocks, thus you need funds to execute other business activities.

Today, I am going to let you know when to re-order stocks and how much stocks you have to order for when you need new stocks. The re-order level is calculated by multiplying the maximum lead time by the maximum usage. The lead time is the average period it takes to order and receive your stocks while the usage is the amount of stocks you sell during that period.  Thus if your maximum lead time is 10 days and the maximum usage per day is 400 units. Then your re-order level will be 10 × 400 units which is 4000 units of goods. Thus, when the units of your goods falls below 4000 units then you will have to make a re-order 

Now, you know when to re-order your stocks, the next challenge will be to calculate the quantity you have to order. You will want to order for a quantity that will minimize your holding cost and ordering cost. The Economic Order Quantity (EOQ)  should be calculated cause it minimizes the total holding and ordering cost. That should be the quantity you should order for. The holding costs include the cost of staff, the storage cost and the cost of deteriorated goods. The ordering cost include delivery cost, documentation cost and others. The annual holding cost is the average stock multiplied by the cost of holding a unit per year (Ch). The average stock is Q/2, where Q is the order quantity.  The annual ordering cost is the Annual Demand (D) divided by the order quantity (Q) multiplied by the cost of placing one order (Co). Thus, the


Annual Holding Cost = Q/2 × Ch


Annual Ordering Cost = D/Q × Co


The Annual Total Cost is the annual holding cost + annual ordering cost, thus, the


Total Cost = (Q/2 × Ch) + (D/Q × Co)


The  formula for the Economic order quantity is given below


             EOQ = /((2 × Co ×D) ÷ Ch)


Where / equals square root and the other symbols represent the same meaning as the ones above. 


Make sure your business is halal. Everything happens according to the will of Allah. Everything should be done deliberately for the sake of Allah. Part of doing something for deliberately for the sake of Allah is hoping for a reward from Him (in this life and life after death).

Halal means anything lawful Islamically.

Evil: Lekki Central Mosque

Asalam alaykum There are mosques and there are evil places that call themselves mosques, Lekki central mosque is one of those places such an evil place. The so called chief imam Ridwan Jamiu is also fake. A mosque, they have two floors. I  thought women where suppose to be upstairs and men downstairs. Yet, he allowed women to be entering the part where men enter, seeing women and men walking and passing through the same door. Women praying downstairs with no division between men and women. When I asked him about it, he said it is allowed. How is that allowed. Islam does not encourage the mixing of different sexes. Where ablution is done in the female part is sometimes dirty, when you are suppose to do ablution in a clean place.The toilets there were dirty and they face the qibla. Toilets are not meant to face the qibla according to Islamic law. There is one toilet there that did not face the qibla. A pit latrine, which i find odd why would there be regular toilets and one pit latri...

Eid Mubarak

Hope you have a good one

Quran 3:56-59

Asalam alaykum "As for those who disbelieve, I will punish them with a severe punishment, in this world and the next, and they will have no helpers.   And as for those who believe and do good works, He will give them their rewards in full. God does not love the unjust.”  This is what We recite to you of the Verses and the Wise Reminder. The likeness of Jesus in God’s sight is that of Adam: He created him from dust, then said to him, “Be,” and he was." Quran 3:56-59 Ma salam.
