Hello Kimberly
Designing the configuration of the posting account in your company is not one setup that is unified across different businesses. That's for one fact, different businesses have difference cases and requirements which in term implies specific type of configuration.
Allow me to elaborate by bringing in a simple example as derived from a real-world business case study. In inventory module, items and general ledger accounts must be linked in order for transactions to be recorded on both sub ledgers and general ledgers in the correct manner. For such topic, you may wonder whether to include the inventory account on the item level (specifically related to this item) , site level (specifically related to this sites regardless of the items), or posting setup level (which is a general setup shared across all items, sites)
The answer would simply be, how do you want to see the inventory balance on your balance sheet ? Are you a manufacturing company which has finished goods, raw materials and semi finished goods that should be reported separately on the balance sheet under an inventory category ? as shown below"
Assets
..
...
Inventory
Finished Goods
Raw Materials
Semi Finished Goods
Or you are a retailer which sells the same items from different locations, which shall be reported separately on your balance sheet as shown below:
Assets
..
...
Inventory
Location A
Location B
Or you simply want to report all your inventory items under one simply category and want them all to be linked to one inventory account on the general ledger level ?
Assets
..
...
Inventory
In case one, item-account assignment is preferable to be done on the item level. While case two would require site-segment feature which link accounts on the site level and finally the third case would go just fine if you include your inventory account on the posting setup level for all items to be assigned.
The same case applies to your customers (as related to the AR account, revenue ..etc) vendors (as related to the payable account, expenses ...etc), checkbooks and fixed assets.
Therefore, when you have a clear understanding for your business and a clear view, GL accounts assignment can be made to meet your requirements in a way that data-entry is easy and errors-free.
If you have a specific case which you are wondering about, you may kindly share and we will provide any relevant assistance accordingly.
