Dropshipping Fashion Shipping Costs in Singapore: What to Charge and What to Absorb

What Goes Into the Delivery Cost

Your dropshipping fashion shipping cost is a stack of separate charges, not just the carrier’s delivery price. The carrier charge covers the parcel’s transport and last-mile delivery. The fulfilment fee covers work such as receiving the supplier’s item, picking it, packing it and handing it to the carrier. Packaging adds mailers, boxes, tape, labels and inserts. Keep these lines separate so you can identify whether a margin problem comes from delivery or fulfilment.

Add surcharges that apply to particular orders, such as address corrections, redelivery, remote-area handling or cash-on-delivery processing. Returns create reverse-shipping, inspection, repacking and refund-related costs. Failed deliveries can add a second delivery attempt or return-to-sender charge, even when the customer receives no product.

Check whether supplier and carrier quotes include GST. The current GST rate in Singapore is 9% (Inland Revenue Authority of Singapore). For total order profitability, exclude product cost and advertising from the delivery-cost subtotal, then assess them separately. ORVX reports realized revenue from delivered orders only, plus return rate and refund value against revenue, so you can compare delivery leakage with product and marketing economics in the profit margin calculator (Source: Inland Revenue Authority of Singapore).

Weight and Size for Dropshipping Fashion Parcels

Actual weight is the parcel’s physical weight after the supplier packs the order, including mailer, carton, inserts and labels. It matters when garments are dense or several items are bundled. A supplier may quote delivery from the product weight alone, then charge more once the completed parcel is weighed. Ask whether the quote uses the item weight or the packed weight.

Volumetric weight prices the space a parcel occupies rather than its mass. Carriers calculate it from the packed length, width and height using their own divisor, then commonly bill whichever is higher: actual or volumetric weight. A puffer jacket in a large box can therefore cost more than its scale weight suggests. Use the outer dimensions after packing, not the garment’s folded dimensions, and compare the supplier’s quoted method with the carrier’s billing rule.

Multi-item orders can reduce delivery cost per item if the supplier consolidates them into one compact parcel, but a larger carton can push volumetric weight into a higher bracket. The destination zone also changes the charge: confirm whether the quoted rate covers every Singapore address or excludes remote, restricted or special-delivery locations. Record packed weight, dimensions, item count and zone for each quote; otherwise a low single-item rate may understate your real dropshipping fashion shipping costs.

Choosing Between Flat Rate and Free Delivery

A flat delivery rate puts a visible charge at checkout, such as a rate you set per order. It is easier to explain and operate when your dropshipping supplier and carrier costs are fairly consistent across Singapore. The product price stays separate from fulfilment, so you can review whether the fee covers delivery without changing every product’s listed price. The trade-off is checkout friction: a customer comparing similar dresses may treat the added charge as part of the total price.

Free delivery shows S$0 to the customer, but the cost still belongs in your order economics. You absorb it through product margin, pricing, or the expected value of the basket. For illustration only, a S$40 order with S$6 delivery cost leaves S$34 before product cost and other expenses; a S$50 order with the same cost leaves S$44. This approach is simpler to communicate in ads and checkout, but less transparent when delivery costs vary. Compare both structures using the profit margin calculator, then check delivered-order profitability rather than counting cancelled or returned orders as revenue.

How to Test a Delivery Threshold

Set the threshold from contribution, not from a round basket value. For each candidate, calculate: contribution after advertising − parcel cost = contribution after free delivery. For illustration only, a S$45 order with S$18 contribution and a S$6 parcel cost leaves S$12. A S$70 order with S$25 contribution leaves S$19. The higher basket is not automatically better if it occurs less often or requires discounts that reduce contribution.

Test two or three candidate thresholds against your actual order mix. Compare the share of orders qualifying, average basket value, contribution per delivered order and total contribution after delivery costs. Review the same measures after returns and refunds: cancelled or returned orders should not count as realized revenue. A threshold that raises basket size but shifts sales toward low-margin items may weaken profit. Recheck after supplier, parcel or advertising costs change. ORVX can show product- and collection-level profitability and contribution after advertising; use its profit margin calculator to model each candidate, rather than adopting a universal Singapore threshold.

How to Read the Worked Cost Example

Read the worked example from the inputs down, rather than starting with the final margin. Identify the customer delivery charge first, then each cost line paid or incurred for that order, such as the supplier or carrier charge and any other delivery-related amount shown. Check that every input uses the same currency and tax basis; a GST-inclusive charge should not be compared with a GST-exclusive cost. Singapore’s current GST rate is 9%, according to the Inland Revenue Authority of Singapore/basics-of-gst/current-gst-rates) (Source: Inland Revenue Authority of Singapore).

Next, add the cost lines to reproduce the example’s absorbed delivery cost. Then compare the customer charge with that total: absorbed cost equals total delivery cost minus the amount collected from the customer. If the result is positive, the store is funding that difference on the order. If the customer charge is higher, the difference offsets delivery cost, but it should not be mistaken for product profit. Recalculate the example whenever a supplier, parcel specification or delivery fee changes.

Turn the Comparison Into a Checkout Policy

Turn the comparison into a rule matrix. Apply a destination rule first: use the Singapore delivery charge for local addresses, and a separate zone or quoted charge for destinations with different carrier costs. Apply a parcel rule next: a lightweight mailer can use one rate, while a carton, multi-item order or bulky garment should use another. Then apply basket value: charge delivery below the contribution-tested threshold and waive or reduce it above that threshold. State whether each charge includes GST; Singapore’s current GST rate is 9%, according to the Inland Revenue Authority of Singapore (Source: Inland Revenue Authority of Singapore).

After launch, monitor the rule by delivered orders rather than orders placed. Compare delivery revenue collected with actual parcel cost, then check contribution after advertising, checkout conversion, average basket value and return or refund value. A rule that raises the fee but lowers completed orders may reduce contribution overall. A free-delivery threshold that increases basket value can still fail if the extra items add more fulfilment cost than profit. ORVX can show product and collection profitability, delivered revenue, return rate and refund value, so review these by destination, parcel type and basket band before changing the policy.

The right delivery policy is the one whose customer charge, absorbed cost and order-value rules remain clear after every relevant parcel cost is included. Review those inputs regularly, then use order-level profitability reporting to decide whether to keep, change or segment the policy.
