I'm trying to make my own application and currently thinking on the amortization section. Is there a recommended technique for periodic calculations for a variable amount of accounting items at a time?
Well that is the common question. I'll try to make it less common: I have some cars and I need to calculate amortization for them every month. If I will make a document for this calculation for each car it will take lots of time to make them every month. Will someone suggest a better solution?
It's common practice to use a catalog for such items and a register for storing and accumulating of initial cost and depreciation. Then you use one document (without mention of each item) for calculating amortization for certain period of time.
