Landed Cost Adjustment (LCA) Explained

Understand how Landed Cost Adjustments work in Blackpurl for both parts and units, and how to allocate additional charges to inventory cost.

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.

What Is a Landed Cost Adjustment?

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.


Parts: How to Allocate a Landed Cost Adjustment

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.

Shows the same 'Applying other charges to invoice items' dialog but with the Details tab selected (highlighted in red bo


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.

Parts: Including a Third-Party Charge in a Landed Cost Adjustment

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:

  • Once as a positive value using the relevant Fee code

  • Once as a negative value using the same Fee code

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.


Units: How to Allocate a Landed Cost Adjustment

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.

You can then select the appropriate Adjustment Category to use for adjusting the unit inventory costs.

Option 1: Landed Cost with a Separate Vendor Invoice

Use this option when you have a separate Tax Invoice payable to a freight company or other third party.

With this option you will populate the Landed Cost line item with:

  • A description

  • The pre-tax cost of the landed cost

  • The expense category to use for any unallocated amounts

  • The vendor who's bill you are recording as a landed cost

  • The vendors invoice number

  • The tax code to use for calculating tax on the vendors bill

Option 2: Landed Cost with No Vendor Invoice

Use this this option when you simply want to expense a landed cost against the units received.

With this option you will populate the Landed Cost line item with:

  • A description

  • The pre-tax cost of the landed cost

  • The expense category to use for any unallocated amounts

Proportional allocation of landed costs against the units received

For each landed cost entry you will see that the Pre-tax cost has been split between "Allocated" and "Expensed".

When receiving a single unit, the pre-tax cost will always be fully allocated to the single unit.

But when multiple units are being received, the pre-tax cost is proportionally allocated to the received units based on the cost of each unit and what percentage it is of the total cost of all of the units being received. Depending on how this calculation works out, it may result in a small portion of the landed cost not being allocated to the units received.

Once the landed cost has been added to the list, you can use the expand icon to see how much of the landed cost is being allocated to each unit.

End Result After Confirming

If you have no accounting integration

  • The Unit Records will include both the cost of the unit as well as a cost line for each landed cost that was allocated to the unit.

If you have accounting integration

  • The Unit Records will include both the cost of the unit as well as a cost line for each landed cost that was allocated to the unit.

  • If you nominated a vendor on the Landed Cost Adjustment line, a Vendor Invoice will integrate into your accounting package so the dealership can pay that vendor (for example, Smith and Co). This vendor bill will contain a line item for each unit the landed cost was allocated to as well as an additional line if there is an unallocated amount.

  • Otherwise if you only specified an Expense Category with no vendor, a journal entry will be posted adjusting the inventory GL for each unit received as well as an additional journal entry if there is an unallocated amount.
