How I Track and Cut Sellerboard Shipping Costs

Shipping costs can quietly turn a profitable Amazon product into a weak one when they are entered once and never reviewed again.

Sellerboard helps Amazon sellers see sales, refunds, advertising costs, FBA and FBM shipping, Amazon fees, cost of goods sold, gross profit, and net profit in one dashboard.

That gives me a much clearer picture than looking at sales or Amazon payouts alone.

I can see how much each product keeps after the costs connected to getting it into Amazon and delivering it to the customer.

I can also spot products where shipping, packaging, fulfillment, or inbound freight has increased enough to damage the margin.

In this guide, I will explain how I track those costs in sellerboard and how I use the numbers to find practical savings.

Why Shipping Costs Need Regular Tracking

Shipping is not one simple expense that happens at the end of an Amazon order.

A product can collect transportation, packaging, handling, and fulfillment costs at several points before the sale is complete.

• Freight from the supplier to a warehouse, port, or prep center.

• Customs clearance, duties, brokerage, inspection, and import handling.

• Shipping from the warehouse or prep center into Amazon’s fulfillment network.

• Amazon FBA fulfillment, placement, and related service charges.

• Courier charges for orders fulfilled directly by the merchant.

• Boxes, mailers, labels, tape, protective materials, and inserts.

• Return shipping, replacement deliveries, and unsellable inventory handling.

When one of these expenses is missing, the product can look more profitable than it really is.

The error becomes more expensive as sales volume increases.

A missing shipping cost of only $1 per unit creates a $1,000 profit overstatement after 1,000 units sell.

That is why I treat shipping costs as changing operational data rather than a permanent estimate.

Carrier rates change.

Seasonal surcharges appear.

Packaging dimensions change.

Amazon updates fees and measures products again.

Your profit model needs to change with them.

How sellerboard Handles FBA And FBM Shipping

sellerboard treats FBA and FBM shipping differently because Amazon provides different data for each fulfillment method.

For FBA orders, Amazon fulfillment and related order charges are generally imported automatically.

For FBM orders, Amazon does not know the complete amount you paid your carrier, warehouse, or fulfillment partner.

You therefore need to add those costs through shipping profiles, product-level values, formulas, or exact order-level imports.

The best method depends on how much your shipping costs vary.

A flat profile may be accurate enough when most orders have similar weights, destinations, and service levels.

Exact order-level costs are better when charges change significantly by package, location, carrier, or shipping speed.

How I Track FBA Shipping Costs

For FBA products, I begin with the Amazon fees that sellerboard imports automatically.

I then check whether every cost that happened before Amazon received the inventory is included in the product’s landed cost or another suitable expense category.

• Supplier freight.

• Import duties and customs charges.

• Inspection and quality-control fees.

• Prep-center receiving and processing.

• Labels, poly bags, boxes, bundling, and protective packaging.

• Shipping from the prep center into Amazon.

• Inbound placement or shipment-service charges.

I divide shipment-level costs across the units that received the service.

Suppose a shipment contains 500 units and the combined freight and preparation cost is $750.

That adds $1.50 to the landed cost of each unit.

Leaving out the $1.50 would overstate the product’s profit on every sale.

I also watch for sudden changes in the FBA fulfillment charge.

A change in weight or dimensions can move a product into a more expensive fee tier.

When the fee increases unexpectedly, I compare Amazon’s stored measurements with the real packaged product.

I also compare the new fee with previous periods to see exactly when the change began.

How I Track FBM Shipping Costs

FBM shipping needs more manual attention because the seller controls the fulfillment process.

The real cost may include the carrier label, packaging, warehouse handling, labor, fuel surcharges, insurance, and residential or remote-area fees.

I begin by grouping orders that behave similarly.

• Orders with the same package size and weight.

• Orders shipped through the same carrier and service level.

• Domestic and international deliveries.

• Single-unit and multi-unit orders.

• Standard and expedited shipments.

• Orders handled internally and orders fulfilled by a third-party warehouse.

I then choose the simplest shipping profile that still produces a reliable estimate.

A profile can apply to all products or selected SKUs.

It can also calculate costs using order price, units, weight, zones, tiers, and active date ranges.

The date-range option is useful when courier rates or seasonal surcharges change.

Instead of overwriting the old rate, I can give the new profile a start date and preserve the correct historical profit calculations.

I also include pick-and-pack expenses when my warehouse charges for handling each package or unit.

That can include a fixed package fee plus a variable cost for additional units.

When costs vary too much for a profile to remain useful, I use exact per-order data from carrier or warehouse reports.

How I Check Whether The Numbers Are Accurate

A shipping profile is only useful when it stays reasonably close to what the business actually pays.

I test the setup against recent invoices instead of assuming the first estimate is correct.

• I select a recent period with a meaningful number of orders.

• I total the carrier, warehouse, packaging, and handling charges for that period.

• I compare the real amount with the shipping expense shown in sellerboard.

• I investigate material differences by product, carrier, destination, or package type.

• I update the profile or import method when the difference is too large.

I do not expect a simple average profile to match every order exactly.

The goal is to keep the total and product-level calculations close enough to support good decisions.

A large difference usually means the profile is too broad, a surcharge is missing, or the business has started shipping a different order mix.

How I Find Products With A Shipping-Cost Problem

Once the cost setup is reliable, I use the dashboard to find where shipping is taking too much of the selling price.

I begin at the account level to see whether total shipping expense is rising faster than sales.

I then move to the product view and compare SKUs over the same date range.

I also compare shipping cost as a percentage of revenue.

A $6 shipping charge may be manageable on a $60 product but difficult to absorb on a $15 item.

The percentage helps me compare products with different selling prices more fairly.

How I Reduce FBA Shipping And Fulfillment Costs

The data tells me where the problem is, but the saving usually comes from changing the operation outside sellerboard.

For FBA products, packaging is one of the first areas I review.

• I remove unnecessary empty space without reducing product protection.

• I test lighter packaging materials when they still protect the item properly.

• I check whether a small change can keep the product below a size or weight threshold.

• I compare single units, multipacks, and bundle configurations.

• I confirm that new packaging still meets Amazon’s requirements.

I then review how inventory moves into Amazon.

Consolidating shipments can lower the freight cost per unit when the inventory plan supports a larger shipment.

However, sending too much inventory can replace freight savings with storage and cash-flow problems.

I therefore compare freight savings with sales velocity, stock coverage, storage costs, and the risk of the product slowing down.

I also compare freight methods instead of automatically choosing the cheapest quoted rate.

A slower option may reduce freight but create a stockout that costs more in lost sales and ranking.

The better decision is the method that protects the full business result.

How I Reduce FBM Shipping Costs

FBM gives the seller more control, which also creates more places to save money.

I begin with the orders or SKUs showing the largest gap between real shipping invoices and the amount currently modeled.

• I compare carrier rates for the package sizes and zones I use most often.

• I negotiate based on real shipment volume rather than estimated future volume.

• I check whether a different service level can meet the promised delivery time at a lower cost.

• I redesign packaging when dimensional weight is driving the charge.

• I reduce unnecessary packaging steps and material where product safety allows it.

• I compare internal fulfillment with third-party warehouse pricing.

• I investigate repeated remote-area, address-correction, residential, or fuel surcharges.

• I adjust free-shipping thresholds or product pricing when the economics no longer work.

I do not judge a carrier only by the label price.

Delivery failures, damage, customer complaints, and support work also create costs.

The cheapest carrier is not a saving when it creates more replacements and refunds.

Do Not Forget Packaging And Handling

Shipping labels are only one part of merchant fulfillment.

Boxes, envelopes, inserts, labels, tape, protective materials, and warehouse labor also reduce the amount left from each order.

These costs can be modeled through COGS, FBM pick-and-pack settings, product-level expenses, or variable expense rules depending on how the business charges them.

The important point is that each expense should be included once and only once.

Adding the same packaging charge to both COGS and pick-and-pack would understate profit.

Leaving it out entirely would overstate profit.

Returns Can Create A Second Shipping Loss

A return can create more than a refund.

The business may also lose outbound shipping, return shipping, packaging, fulfillment charges, handling time, and part of the product’s value.

That makes return-rate analysis part of shipping-cost optimization.

When a product has high shipping expense and frequent returns, I review the return reasons before negotiating another carrier rate.

The bigger saving may come from improving the product, packaging, instructions, images, sizing information, or listing expectations.

My Weekly Shipping-Cost Review

I keep the weekly review simple enough to repeat.

• I compare total shipping expense with the previous week and the same period before it.

• I check which products had the largest shipping-cost increase.

• I review any sudden FBA fee or product-dimension change.

• I compare FBM shipping profiles with recent carrier or warehouse invoices.

• I look for seasonal surcharges or new fees that need a dated profile.

• I review return-heavy products that generate repeated delivery costs.

• I record one clear action for any meaningful problem.

The action might be correcting a profile, requesting a product remeasurement, changing packaging, negotiating a courier rate, or adjusting the selling price.

The dashboard becomes valuable when it leads to an operational decision.

Common Shipping-Cost Tracking Mistakes

• Using the supplier price as COGS while ignoring freight and preparation.

• Assuming Amazon imports every cost connected to an FBA product.

• Leaving FBM shipping blank because Amazon already deducted referral fees.

• Using one flat FBM rate for products with very different weights or destinations.

• Overwriting an old rate instead of using a new effective date.

• Ignoring packaging and warehouse handling.

• Entering the same expense in two different cost areas.

• Comparing carrier quotes without including surcharges and delivery performance.

• Looking only at total shipping instead of product-level shipping.

• Reducing packaging so aggressively that damage and returns increase.

Frequently Asked Questions

Does sellerboard Track FBA Shipping Costs Automatically?

sellerboard imports Amazon FBA fulfillment and related order fees, but you still need to account for supplier freight, customs, preparation, packaging, and inbound transportation when those costs are not included elsewhere.

How Does sellerboard Calculate FBM Shipping?

FBM shipping can be modeled with profiles based on factors such as products, price, units, weight, zones, tiers, and date ranges.

You can also use product-level values or exact order-level shipping data when that is more accurate.

Should Inbound Shipping Be Included In COGS?

Inbound freight is often included in landed COGS because it is a direct cost of getting each unit ready for sale.

The exact accounting treatment should be consistent with your bookkeeping method and professional advice.

Can I Use Different FBM Shipping Costs For Different Periods?

Yes, sellerboard supports period-based shipping profiles so a new rate can begin on a selected date without changing the historical rate used for older orders.

How Often Should I Review Shipping Costs?

I recommend a short weekly check for major changes and a deeper monthly reconciliation against carrier, warehouse, prep-center, and Amazon fee records.

Can sellerboard Reduce My Shipping Costs Automatically?

sellerboard identifies where shipping is reducing profit, but you still need to make the operational change.

That change may involve packaging, carriers, warehouse terms, shipment size, fulfillment method, pricing, or product design.

Final Thoughts

Shipping costs become easier to control once they are visible at the product and order level.

sellerboard helps me connect those costs with sales, Amazon fees, advertising, refunds, COGS, and net profit.

For FBA, I focus on landed cost, inbound freight, packaging dimensions, and unexpected fee changes.

For FBM, I focus on accurate shipping profiles, packaging, pick-and-pack costs, carrier invoices, zones, and surcharges.

The goal is not to reduce shipping at any cost.

The goal is to lower the total cost without creating more damage, delays, returns, stockouts, or customer complaints.

Start by checking whether your existing shipping data matches recent invoices.

Then use the dashboard to find the product with the clearest cost problem and fix that one first.
