Top 10 Inventory Mistakes To Avoid

Inventory control is one of the most important financial management tools within MLS 2026.

Poor inventory procedures can result in:

•lost profits

•excess stock

•missing parts

•accounting discrepancies

•incorrect pricing

•unnecessary purchases

•poor cash flow

The following are the most common inventory mistakes, and how to avoid them.


1. Manually Adjusting Inventory Instead Of Using Stock Input

One of the most common mistakes is directly changing:

•stock quantities

•costs

•pricing

inside the Inventory Editor instead of processing parts through:

👉 Stock Input

Manual adjustments bypass:

•average cost calculations

•purchasing history

•accounting updates

•vendor tracking

•inventory statistics

Better Practice

Always receive parts through:

👉 Purchase Orders and Stock Input

whenever possible.


2. Failing To Use Purchase Orders

Phone orders and handwritten notes create:

•missing parts

•forgotten orders

•vendor confusion

•duplicate purchases

•inaccurate on-order quantities

Better Practice

Use the Purchase Order system consistently so:

•orders are tracked

•quantities are controlled

•pricing history is maintained

•backorders are visible


3. Stocking Parts That Do Not Sell

Slow-moving inventory ties up:

•cash

•shelf space

•purchasing power

Many businesses accumulate large quantities of parts that rarely move.

Better Practice

Regularly review:

•Holdover Reports

•Sales Summaries

•Below Minimum Reports

Return or discontinue slow-moving items whenever practical.


4. Allowing Sales Representatives To Control Inventory Decisions

Sales representatives are valuable resources, but their goal is:

👉 selling inventory.

Not every “special purchase” is actually beneficial to your business.

Better Practice

Use:

•actual sales history

•lost sales data

•usage reports

•turnover statistics

to determine what should be stocked.


5. Using Inconsistent Part Descriptions

Descriptions such as:

•Oil Filter

•Oil Filt

•OIL FILTER

•Oil Filter Large

make searching and reporting difficult.

Better Practice

Develop standardized naming conventions for:

•descriptions

•manufacturers

•type codes

•location codes

Consistency dramatically improves:

•searches

•reports

•ordering

•employee efficiency


6. Ignoring Location Codes

Without organized locations:

•parts become lost

•duplicate purchases occur

•technicians waste time searching

Better Practice

Assign clear location codes to:

•shelves

•bins

•storage rooms

•warehouse areas

Maintain location accuracy whenever inventory is moved.


7. Not Reconciling Physical Inventory

Computer records eventually drift from reality due to:

•damaged parts

•misplaced inventory

•entry errors

•theft

•unbilled usage

Better Practice

Perform regular:

👉 Stock Balancing

using physical inventory counts.

Small regular reconciliations are much easier than major corrections later.


8. Overriding Pricing Without Understanding Markup Structure

Random manual pricing changes often create:

•inconsistent profits

•underpriced items

•customer pricing confusion

Better Practice

Use:

👉 Pricing Tables

to maintain consistent markup policies across inventory.

Review pricing regularly as vendor costs change.


9. Failing To Process Cores Promptly

Unreturned cores create:

•lost credits

•unnecessary expense

•cluttered storage

•accounting confusion

Better Practice

Run:

•Outstanding Core Reports

•Core To Return Reports

regularly and process returns quickly.


10. Deleting Inventory Records

Deleting parts removes:

•sales history

•pricing history

•vendor information

•inventory statistics

Very little storage space is required for inactive records.

Better Practice

Keep inventory history whenever possible.

Instead of deleting parts:

•mark them inactive

•reduce stocking levels

•leave them available for historical reference


Additional Common Problems

Forgetting To Save Changes

Changes are not retained until:

👉 Save

is selected.


Editing Workorders After Posting

Manual edits after posting can affect:

•inventory quantities

•accounting

•reporting accuracy


Ignoring Lost Sales

Repeated lost sales indicate:

👉 possible stocking opportunities.


Leaving Backorders Open Indefinitely

Open backorders create:

•incorrect purchasing totals

•inaccurate on-order quantities


Not Updating Retail Prices

Vendor costs change constantly.

Failing to update pricing gradually reduces profitability.


Recommended Best Practices

•Use Purchase Orders consistently

•Receive parts through Stock Input

•Reconcile inventory regularly

•Maintain organized locations

•Standardize descriptions and codes

•Use Pricing Tables

•Review sales history frequently

•Monitor lost sales carefully

•Process cores quickly

•Preserve historical inventory records

•Train all employees on workflow procedures

•Audit inventory reports regularly
