Core Charges Defined
A “core” is a used and non-functioning part that can be recycled and sold as a remanufactured part. Some of the recyclable parts that manufacturers consider core parts are water pumps, motors, circuit boards, certain air conditioning compressors, and more. The return of core parts to manufacturers lowers the cost of the parts and related repairs. A core item may also contain valuable materials, such as copper and aluminum, even when no one plans to remanufacture it.
A seller adds a core charge (or fee) to the price of a replacement part as a refundable deposit. Customers can recover the deposit by returning the old part within the specified period. The purpose is to encourage the return of reusable parts for remanufacturing or recycling. The California Bureau of Automotive Repair’s explanation of core charges provides a good description on how these deposits work and why suppliers use them.
If the customer does not return the core item within the required period, they generally forfeit the deposit. The business must then account for the retained amount appropriately. Some cores have no value because of their condition, but a supplier may still require a core charge on the replacement part.
In some cases, the technician collects the old part at the time of the repair. In that case, the customer receives their credit at the time of the service call.
Core Expenses
It is also possible that the service company may not charge a core fee but is willing to pay for core items. For example, a company might be willing to pay for certain items that have scrap value. Businesses may purchase items containing copper and aluminum and resell them for a profit. In this case, the business does not charge the customer a core fee but records a core expense and eventually earns core income.
Example Scenarios
- You remove a water pump from a car and take it to an auto parts store for a replacement. They will sell you a water pump and charge you for the core. They will immediately credit you the same amount for the core since you brought it with you. The auto parts store sends the water pump to a company that will recondition it, and the store receives payment for the core.
- You go to the auto parts store for a water pump. They will sell you a water pump and charge you for the core. They will credit you back the same amount once you return with the old water pump (the core). The auto parts store sends the water pump to a company that will recondition it.
- You might purchase a radiator from a parts store. They do not charge you a core fee. You might sell that radiator back to the store or another company that buys scrap metal.
- You run a service call and replace a circuit board. That board has a value of $30.00 if it is returned to the manufacturer for reconditioning. You replace the board and optionally charge the customer for the core. You immediately give them credit for the core since you are onsite and will take the circuit board with you. The office collects the cores from each truck and sends them back for credit.
Managing Core Charges and Returns
Before setting up a process to manage core charges, make some management decisions. Pretend as if you did not have software and the entire policy and procedure were going to be handled with paper and pen. You have to work out the entire manual process first before applying that process to software.
One decision you must make is how detailed you want your financial reporting for core item activity. Most companies will have a single income account and a single cost of goods sold account for all core items. Do you wish to offset the core charge (income from the customer) with the core expense (money paid to the customer) for each specific item? That method will give you more detailed information, but it will require far more work to set up, manage, and audit for accuracy.
The following example considers a simplified approach that offers a good combination of financial reporting and daily simplicity.
1. Track core charges separately.
Use a dedicated item or transaction category called Core Charge. You can assign it to an existing income account, such as Parts and Materials or Other Income, or create a separate account for core charge activity. The right approach depends on your accounting policies and how much detail you want in your reports.
2. Track core returns separately.
Use an item or category called Core Charge Return to record cores received from customers and returned to vendors. Track the physical parts and their associated values so you can reconcile the amounts due from suppliers with the cores actually returned.
Core charges and core returns affect different parts of your financial records. You should not automatically treat a customer deposit that remains refundable as earned income. Depending on the transaction and your accounting method, you may need to record it as a liability. The liability may remain until the return period expires or you otherwise resolve the obligation. Work with your accountant to determine the appropriate account classifications and entries.
Tips
- Keep core-eligible parts identifiable. If items include a potential core return, consider adding “(core return eligible)” to the end of the item description.
- Use clear descriptions. If you use a generic core item description, always enter a good description of the specific item you are returning. Include the part number, manufacturer, and any other information needed to match the part to the supplier’s credit.
- Track core returns from the field to the supplier. Establish a process for collecting cores from technician trucks, recording what has been received, and documenting when each item is returned to the vendor.
- Apply core charges consistently. If core charges are sometimes calculated as a percentage of the item being sold, establish a consistent calculation method. Many suppliers set core charges at a fixed amount for a particular part, so confirm the supplier’s terms before applying a percentage.
- Monitor return deadlines. Keep track of the supplier’s return window and any requirements for the condition of the part. A late or rejected core return may mean losing the expected credit.
Usage and Accounting for Core Charges
Create invoices and sell items as usual, keeping the core charge separate from the replacement part.
- When collecting a core fee: Add the core charge as a separate line on the invoice. Include a clear description and the correct amount. This makes the charge visible to the customer and easier to track in your financial reports.
- When receiving a core from a customer: Record the return and issue the appropriate customer credit. If the customer is entitled to a refund, make sure the credit is recorded against the original core charge or the appropriate liability account.
- When returning a core to a vendor: Record the physical return and the credit the vendor provides. A vendor credit can be applied against a vendor bill or handled according to the supplier’s refund process. Keep the vendor’s documentation with the transaction so you can reconcile the credit later.
For businesses that track parts closely, this process should also account for inventory quantities and values. The returned core is a physical item that needs to be tracked until it is sent back to the supplier, sold for scrap, or otherwise disposed of. For more information about the financial records behind these transactions, see Aptora’s guide to creating and using a warranty reserve account in accounting, which discusses how contractors can track obligations and related costs.
A More Detailed Methodology
If you wish to have more detailed financial reporting, there are several options to consider. You can improve your core-related reporting without necessarily creating a complicated system. Decide whether the additional detail is worth the effort required to maintain it.
1. Create dedicated accounts for core activity.
In the simplified approach, existing accounts are used to track core fees and expenses. You could add an inventory asset account called Inventory – Core, along with separate income and cost of goods sold accounts for core item activity. This makes it easier to identify core-related transactions in financial reports.
2. Use a separate department or category.
Set up a department called Core Items, or something similar, and assign each related transaction to it. This provides more detailed reporting without requiring a separate account for every core item.
3. Create multiple core items.
You may find that approximately ten core items will do a reasonably good job of covering the various core item categories you wish to track. For example, you might create a core item called CoreChargeReturn010 for all $10.00 core charges. You can use item categories to further define this activity.
4. Create a specific core charge item for each related part.
The most detailed reporting would come from creating a specific core charge item for each related item you sell. Let’s say you sell a circuit board that has a core charge. If you need to relate that circuit board to its core charge, create a corresponding core charge item. This makes it easier to match the replacement part, the core deposit, the customer credit, and the vendor credit.
5. Track serial numbers when necessary.
If you handle serialized parts, consider whether tracking the serial number of each returned core would be worthwhile. This can be especially useful when suppliers require you to return specific parts or when warranty and core-return requirements overlap.
Detailed records help you identify outstanding core charges, returns with credits, and parts you still need to send to a supplier. Your chart of accounts should support the level of reporting you need without making routine transactions unnecessarily complicated.
