# Cost allocation: Distribute shipping costs across customers and products

Which method should you use to allocate shipping costs fairly across customers and products? This guide explains proportional methods, margin effects and implementation steps.

9 September 2026

## Quick answer

Allocate shipping costs proportionally by weight, volume, order value or item count. Pick the method that matches your product mix, pricing strategy and invoicing in Switzerland. Run tests with real orders, review margins and communicate the rules to sales and customers.

## Why allocate shipping costs?

Shipping costs affect margins and price perception. Transparent allocation supports accurate contribution margins, fair customer pricing and reliable internal reporting. You need one documented approach shared across accounting, sales and operations.

## Common allocation methods

Weight-based: Distribute costs by gross or net weight. Good for heavy items. Volume-based: Use cubic metres or dimensions. Best for bulky, light products. Value-based: Allocate by order or item value. Charges higher-value goods more. Per-unit: Split costs equally per item. Simple for homogenous SKUs. Flat per-order fee: One fixed charge per delivery. Clear to customers but less precise internally.

## Combined and hybrid approaches

Many companies use a weighted mix. Example: 50% weight, 30% volume, 20% value. Hybrids balance fairness and simplicity. Define exact formulas and rounding rules. Automate calculations in your ERP, billing or ecommerce backend.

## Effects on margins and pricing

Allocation changes product margins. Light, high-value items tend to gain, heavy low-value items lose margin. Value-based allocation raises margins on cheap items. Check margins before and after allocation. Adjust list prices, tier prices or discounts if needed. Consider customer reactions in B2B and B2C contexts.

## Accounting and compliance in Switzerland

Record shipping costs consistently: as part of goods cost or as selling expense. For VAT, verify how to show shipping lines on invoices. Keep documentation of allocation rules for audits. Ask your fiduciary for advice if unsure.

## Practical implementation steps

1) Choose a model and document the formula. 2) Pull weight, volume and value from your ERP or shop. 3) Implement the calculation in ERP, billing or with an export script. 4) Test with sample orders. 5) Monitor margins and tweak rules every six months. 6) Inform customers and sales of changes.

## Frequently asked questions

Which method works best for mixed product ranges? Hybrid models usually work best. Combine weight and volume and add a small value component to reduce outliers.

Should I show shipping costs separately on invoices? You can show shipping separately or include it in product prices. Separate lines are clearer for customers and usually simpler for VAT handling.

How do I trial a new allocation rule safely? Simulate the rule on historical orders. Compare resulting margins and the impact on top SKUs. Roll out with a pilot customer or product group first.

How often should we review allocation rules? Review at least twice a year and immediately after major price, product or transport cost changes.
