Use the shipping tools together when you need to understand both the physical parcel and the financial impact of dispatching it.
Measure the Parcel After It Is Packed
Packaging protects the item, but it also changes the parcel’s dimensions, weight and cost. Aim for enough protection without unnecessary material or unused space.
Finished Dimensions
Carrier limits apply to the parcel you actually hand over, including its external packaging.
Check Finished Parcel →Finished Weight
Boxes, protective material, tape and inserts all contribute to the final shipping weight.
Check Weight & Size →Item Protection
Use enough packaging to protect the product while avoiding unnecessary bulk that can make fulfilment more expensive.
Compare Suitable Services →Packaging Cost
Mailing bags, boxes, tape, labels and protective material are real selling costs and should not be ignored.
Add Packaging to Profit →Pack first, then weigh and measure before purchasing postage.
Compare the Service, Not Just the Headline Price
Courier quotes and terms change. Compare current services against the requirements of the particular parcel instead of assuming one carrier is always best.
Royal Mail
Compare the relevant Royal Mail service against your parcel size, required tracking, delivery speed and protection needs.
Evri
Compare the current quote and service terms for the parcel rather than judging on price alone.
DPD
Include delivery speed and service requirements when deciding whether the quote represents good value for the order.
Another Courier
SellerStack’s comparison tool lets you enter another suitable carrier alongside the standard comparison options.
Match the Workflow to How You Sell
The best fulfilment setup changes as order volume, marketplace count and operational complexity increase.
Simple Manual Dispatch
A marketplace label, QR code or straightforward online postage workflow may be enough when you only send a few orders.
Dedicated Shipping Workflow
Importing orders and printing labels becomes more valuable when dispatch is a regular part of the week.
Centralised Fulfilment
Shipping software can reduce repetitive work when orders arrive from several marketplaces or stores.
FBA or Other Fulfilment Services
Outsourcing can reduce per-order handling work, but storage and fulfilment costs become part of the profitability decision.
Solve a Shipping Problem
Start with the issue causing the most friction in your current fulfilment process.
