A Landed Cost Adjustment (LCA) in Blackpurl lets you allocate additional charges — such as freight, shipping, or environmental fees — directly against the inventory cost of parts or units you receive. This gives your dealership a more accurate picture of true profitability when those parts or units are sold. Confirm with your team whether your dealership uses Landed Cost Adjustments before proceeding.
​

When a dealership receives parts or units from a vendor, the Vendor Invoice often includes charges beyond the cost of the items themselves — freight, shipping, environmental fees, and similar costs. Normally these charges are processed separately, meaning they don't affect the recorded inventory cost of the items received.
​

With a Landed Cost Adjustment, those Other Charges can be folded into the final inventory cost of the parts or units. When those items are sold, the cost of sale reflects the true total cost, giving you more accurate profitability reporting.
​

On a parts Vendor Invoice, once you add a fee in the Other Charges section, the option Include other charges as part of the inventory cost? appears. Enable it by switching the toggle on.
​

By default, Blackpurl proportionally allocates the Other Charges across all line items on the Vendor Invoice. The allocation is based on each line item's cost as a proportion of the total cost of all line items.
​

The Applying other charges to invoice items window opens so you can review the proportional allocation on the Summary tab.
​

You can accept the proportional allocation as-is, or switch to the Details tab to adjust individual line items. From there you can reduce or remove the allocation for specific items, or increase it for others.
​

As you make changes, watch the Pre-Adjustment and Post Adjustment totals at the bottom of the window. You can toggle between the Summary and Details tabs as many times as needed until you are satisfied with the result. When you are happy, click APPLY CHANGES.
​

The result of the Landed Cost Adjustment is then visible on the relevant line items of the Vendor Invoice.
​

To see a full cost breakdown for any line item, click See how it's calculated. The How Inventory cost is calculated window opens with a detailed breakdown.
​

​

In some cases, a dealership may receive a charge from a separate vendor — such as a freight company or customs broker — that should still be spread across the cost of parts received on a different Vendor Invoice. To handle this, you need to know the third-party charge amount before you process the parts Vendor Invoice.
​

To allocate a third-party cost against the inventory items on a parts Vendor Invoice without changing the Vendor Invoice total, add the charge to the Other Charges section of the parts Vendor Invoice twice:

The two entries cancel each other out in the Vendor Invoice total, keeping the total correct while giving you an Other Charges line to allocate.
​

When you use the Landed Cost Adjustment tool to allocate Other Charges, allocate the positive charge only in the Details tab. Do not allocate the negative charge — allocating both will cancel out the adjustment and achieve nothing.
​

This leaves the parts Vendor Invoice at the correct total while recording the third-party cost as part of the Landed Cost Adjustment against inventory. Note that this process does not pay the third-party invoice — you still need to process that invoice separately in your accounting package or in Blackpurl.
​

When receiving a unit, the unit receiving screen includes an option to Allocate Landed Cost Adjustment. Switch the toggle on to enable it — a Landed Cost Adjustment section will appear below the unit Vendor Invoice section.
​

Complete the top section with the actual Vendor Invoice details for the unit, then complete the Landed Cost Adjustment section for any additional charges such as freight.
​

Use this option when you have a separate Tax Invoice payable to a freight company or other third party. In the Landed Cost Adjustment section, enter the freight cost and nominate the vendor who submitted the invoice. Include their Vendor Invoice number in the Reference field.
​

For example: if Smith and Co are charging the dealership for freight on a separate Vendor Invoice, the Landed Cost Adjustment entry would include Smith and Co as the vendor and their invoice number as the reference. This will generate a Tax Invoice in your accounting package for Smith and Co.
​

Fill in the relevant information and click Save to accept the Landed Cost Adjustment line. If you need to add more than one adjustment, click Add more costs to add additional lines.
​

Use this option when you want to add a freight component to the unit record but there is no separate vendor or Tax Invoice involved. In this case, ensure the Category field is set correctly — this determines which General Ledger account the cost will hit in your accounting package. Leave the vendor field blank.
​

This adds a freight component directly onto the Unit Record without generating a separate vendor payable.
​

Review both the Unit Vendor Invoice section and the Landed Cost Adjustment section. When you are satisfied with all entries, click Confirm receiving.
