# Inventory Setup

> Before running our POS solution, it's strongly encouraged that our partners make sure the proper initial setup is completed in Business Central.

## Automatic cost posting

> **Warning:** It is very important that **Automatic Cost Posting** is **NOT** enabled in **Inventory Setup**.

Although **Automatic Cost Posting** is by default enabled in Business Central, the POS doesn't support this particular configuration choice. NaviPartner creates a job with a specific purpose to run the cost posting instead.

## Automatic cost adjustment

> **Warning:** It is very important that **Automatic Cost Adjustment** in **Inventory Setup** is set to **NEVER**.

Although **Automatic Cost Adjustment** is by default activated in the **Inventory Setup**, the POS doesn't support this configuration choice. Instead, NaviPartner creates a job with a specific purpose to run the cost posting instead.

## Verify cost adjustment after go-live

Because cost adjustment runs through the dedicated job rather than Business Central's automatic cost adjustment, this job must be confirmed as part of migration/go-live. If it is not running, sales can post with **no cost of goods sold (COGS)**, which makes margins look inflated and misleading.

* **Verify that the adjust-cost-prices job queue entry is running** after go-live. Confirm the relevant cost adjustment / cost posting job queue entries are present, set to **Ready**, and actually processing.
* **Understand the impact of a missing cost adjustment.** If cost adjustment does not run, item ledger entries are not adjusted and related sales can be posted without COGS — the result is sales with no cost booked and margins that appear far higher than reality.

> **Warning:** Confirm this at go-live, not weeks later. The longer cost adjustment is not running, the more posted entries accumulate without a cost, and the more misleading the margin figures become until the job catches up.
