Discharging zakaat

Q: I have a retail business that's just breaking even month on month, alhumdulillah. This year has been my hardest year and revenue is declining. I have approximately R2.8mil in stock that is very slow moving and I want to know, how do I go about paying the zakaat on my business this year? The revenue generated weekly is used for salaries, day to day expenses and purchasing of fast selling goods. There are weeks that I don't take any wage, so I need to plan ahead, so that my business zakaat can be discharged accordingly. My zakaat date is 1st Rabi Al Awaal

Q: I need to pay zakaat. Can I purchase a flat and give my sister as she does not own a house and she is living on rent with not good income, even her husband is not earning enough?

Q: The following has occurred and I am not sure if it counts as my zakaat being fulfilled.

We have a neighbor who is a worthy recipient of zakaat. My parents were in the process of helping them amend some part of their home when my zakaat became due. I had informed them of it and so my mother gave the man who is doing the fixing, the money to buy the tools and materials with the intention of zakaat for our neighbor. It was not given to the man doing the fixing in lieu of his labour but rather for the material needed to fix our zakaatable neighbors house.

Is my zakaat considered as valid ?

Q: Instead of paying zakaat with cash, can a person give goods to that amount that the recipient needs?

Q: An elderly man needs to go for an operation and does not have funds to pay for it. He is a male of 76 years and receives pension from the state government. He does not own a house and is supported by his one daughter.

Q: Does donation to zakaat foundation, or relief help organizations, fulfills the requirement of our zakaat? As we are not directly given zakaat to poor but organization third party.
