Entering Beginning Inventory Balance in Dynamics 365 Business Central


When moving from a legacy system into Dynamics 365 Business Central, one of the areas you want to try and avoid is messing with the inventory G/L accounts. Most systems are usually pretty good with open A/R (Accounts Receivable) and A/P (Accounts Payable) accounts, they can be transferred using the “posting back to the same account” technique that most implementers do. The beginning A/R and A/P general ledger accounts would be based on your entry on the General Journal. This is assuming that the A/R and A/P aging reports matches the general ledger.

Inventory valuation is one of the areas where we find the most discrepancies based on what is entered on the Item Journal¬† from the physical count and the inventory valuation report from the legacy system. Depending on your requirements, sometimes it doesn’t make sense to go through line by line on the item journal to see where the differences are.

Let Business Central Keep Track of Inventory Value

A rule of thumb I always go by is to let Business Central determine what the inventory value should be in the General Ledger based on the positive adjustments posted from the Item Journal. This ensures that the inventory values are accurately reflected in the G/L, aligning with the actual adjustments made within the system when you go live. Always trust Business Central to handle inventory costing calculations. Humans make mistakes, Business Central doesn’t.

Assuming you posted your beginning inventory quantities through the item journal with the proper Unit Amount, now you need to enter the beginning balance in the General Ledger. Let’s further assume you have the following G/L accounts.

11000 – Inventory
58850 – Inventory Adjustment

When you post the item journal positive adjustment, the General Ledger accounts that would be affected would be:

+ 11000 Inventory
– 58850 Inventory Adjustment.

Entering The G/L Inventory Balance

When posting a positive adjustment in the Item journal, it will post a debit to Inventory and credit to Inventory Adjustment.

When you’re ready to enter your beginning G/L balance, enter the G/L balance for Inventory to account 58850. This way, the difference between the inventory G/L balance from the legacy system and Dynamics 365 Business Central will be reflected on account 58850.

If you do not want to reflect the adjustment in the current period due to financial reporting reasons, you can adjust the difference into an asset account. We usually recommend create a separate account (i.e. 11100 – Inventory Suspense) to store this difference until you can depreciate it.

By not posting any general journal entries to the inventory accounts, you’ve ensured that inventory valuation reports will ALWAYS match G/L, making everyone happy in the process.
