To whoever who can help,

If anyone can give me a hand for this it would be greatly
appreciated, I am a quick learner but I lack the technical Excel know-how to
do what it is I need to do.

Allow me to explain the situation: I work for a holding company. We
manage several small businesses and some larger ones. What I need to do is
put in place an accounting system to keep track of each company including the
holding company, mostly pertaining to expenses and revenues.

If I am not mistaken, the simplest way to go about is to have the
holding company and the rest of the companies on one book. Each sheet is a
different company and an identical template is used for each sheet. I am
already using a template that ressembles a petty cash template but I need to
add-on more. To give you an idea of what kind of formula I will be needing,
I can give you an example of a situation that may arise:

-Company A has just been established. We, as the holding company, suggest
that they buy insurance. They accept. We undergo all the procedures for them
to get insurance. The insurance premium costs 450$. We pay this 450$ for
them. So it has to be debited off sheet 1 (the holding company's sheet) as an
expense for us towards Company A. Then it has to be debited off Company A's
sheet + 15% (which is what we charge for services). So in conclusion it's:
-450$ on the holding company's sheet, -450$ on Company A's sheet and
eventually +450$+67.5$ on the company's holding sheet (which is 15% of $450
for services rendered).

On the holding company's sheet, I need to be able to type in the name of a
company when i enter an amount (WHETHER EXPENSE OR REVENUE) and the numbers
to automatically be reflected on that company's sheet and then back again on
the holding sheet with the added 15%.

I hope this is clear. Please do not hesitate to ask more questions. Anyone
who has some useful input would be appreciated.

Sincerely,

Jon
