A 500g parcel (typical eCommerce): Royal Mail Special Delivery £9, DPD Express Next Day £6.50, Amazon Logistics (if FBA) free. Most retailers think DPD is cheapest (it's advertised as such). But Royal Mail can be cheaper on volume, and Amazon is free (but takes commission). AskBiz shows true cost-per-parcel by carrier.

The UK Shipping Cost Myth#
Most UK eCommerce retailers believe: (1) Royal Mail is expensive (old perception). (2) DPD is cheapest. (3) Amazon FBA is too expensive. This leads to: (1) Using DPD for everything (because it's "cheapest"). (2) Missing volume discounts on Royal Mail. (3) Avoiding FBA (even when it's profitable). The reality: (1) Royal Mail Special Delivery £9 per parcel at single rates, but £5-6 per parcel on 1,000+ per year contract. (2) DPD £6.50 per parcel. (3) Amazon FBA: 2.5-3.5% commission (on £25 product = £0.63-0.88 "shipping" cost if you get FBA pricing). Royal Mail with volume discount is as cheap or cheaper than DPD.
Carrier Selection Complexity#
Different carriers excel at: (1) Royal Mail: domestic, good coverage, slow. (2) DPD: domestic, faster, next-day in most areas. (3) Parcelforce: domestic, express, most expensive. (4) Amazon Logistics: FBA only, included in FBA fee. (5) International: DPD cheaper for EU post-Brexit. Retailers should use different carriers for different routes, not one carrier for all.
AskBiz Shipping Route Optimization#
AskBiz logs: (1) Parcel weight, destination. (2) Carrier used, cost. (3) Delivery time. Report: (1) Cost per parcel by carrier. (2) Cost per parcel by destination (domestic vs. international). (3) Delivery speed vs. cost trade-off. (4) Recommendations: "80% of parcels are <500g domestic (UK). Royal Mail at volume rate: £4.50 each. You're using DPD at £6. Switch 80% to Royal Mail, save £1.20 per parcel. On 10K parcels/year, save £12K."
Real Example: UK Seller with 10K Parcels/Year#
A seller used DPD for everything at £6/parcel (£60K shipping cost). After analyzing with AskBiz: (1) 80% of parcels were domestic (DPD not needed for next-day). (2) Switched 80% to Royal Mail at volume rate £4/parcel. (3) 20% international/urgent used DPD at £6. (4) New average cost: (0.8 × £4) + (0.2 × £6) = £4.40/parcel. (5) New total: £44K (saving £16K). Delivery time was acceptable (Royal Mail takes 2-3 days, not next-day, but most customers accept). Profit improved by £16K with no service degradation.
Negotiating Volume Rates: What Most SMBs Don't Realise Is on the Table#
Most small UK sellers assume carrier pricing is fixed — that the rate shown on Royal Mail's public price list or a pay-as-you-go DPD account page is simply what shipping costs. In practice, both major carriers offer negotiated business rates well below their published retail pricing once a seller reaches a modest, sustained volume, and a surprising number of SMBs never ask. Royal Mail's Click & Drop business account tiers give discounted pricing against standard retail postage once a business is shipping regularly, with better rates unlocked as monthly volume grows — but the account has to be actively set up and, in many cases, the discount tier requested rather than applied automatically. DPD works similarly through a contract account rather than its pay-as-you-go online booking: a seller shipping a consistent number of parcels a week can request a account review, and the quoted contract rate is typically negotiated based on volume, average parcel weight, and collection point rather than being a fixed published number at all. A Leicester homeware seller shipping around 120 parcels a week had been booking every DPD shipment through the standard online portal at list price for over a year, never realising a contract account was available to a business of her size. A single conversation with a DPD account manager moved her onto contract pricing with meaningfully lower per-parcel rates, backdated to nothing but effective immediately — the only cost was the time to have the conversation and switch her booking workflow to the contract account. The broader lesson is that carrier rate cards are a starting point for negotiation, not a fixed price, once a business can show consistent volume and is willing to ask. Sellers should revisit their carrier rates at least once a year as volume grows, since a rate negotiated at 50 parcels a week is not the rate that should still apply once volume has doubled. AskBiz's shipping cost tracking makes this an easy conversation to start, because it shows exactly how many parcels went through each carrier and the average cost per parcel over any period — the precise numbers a carrier account manager needs to quote a fair contract rate.
Why Returns Change the True Cost of a Carrier#
Comparing carriers on outbound cost alone misses a large part of the real cost picture for any retailer with a meaningful return rate, and fashion and footwear sellers in particular can get this badly wrong. A carrier that looks cheapest for sending a parcel out can be considerably more expensive, slower, or more operationally painful when that parcel needs to come back. A Manchester online fashion retailer with a return rate of around 28% — typical for clothing — had chosen their outbound carrier purely on the lowest quoted per-parcel rate, without checking return costs at all. It was only when reconciling costs at the end of a quarter that the owner realised their chosen carrier charged a return label fee almost as high as the outbound cost, while a competing carrier offered free returns via a network of local drop-off points as part of its standard business contract. Once true landed cost was recalculated including the return leg — outbound cost plus (return rate × return cost) — the carrier that looked 8% cheaper on paper for outbound shipping was actually more expensive overall once returns were factored in, because nearly a third of parcels came back. The fix was not necessarily to switch carriers entirely, but to shop the return leg separately: some sellers use one carrier for outbound delivery and a different, cheaper returns network for the reverse journey, particularly where a carrier offers convenient drop-off points that reduce the friction (and therefore the abandonment) of the return process for the customer. For any retailer with a return rate above roughly 15-20%, return cost deserves equal billing with outbound cost in a carrier decision, and for very low-return categories like consumables or one-size items, outbound cost alone is a reasonable basis for comparison. The mistake most SMBs make is comparing carriers using only the number on the outbound label, because that is the number they see first and most often — but for categories with high returns, it is frequently not the number that determines which carrier is actually cheaper.
Post-Brexit: Domestic vs International Carrier Choice and the Customs Burden#
Shipping to EU customers post-Brexit introduced a layer of complexity that does not exist for domestic UK parcels, and carriers differ significantly in how much of that burden they absorb versus pass on to the seller. Every parcel leaving the UK for the EU now needs a commercial invoice and correct customs (HS) coding, and getting this wrong causes delays, returned parcels, or unexpected charges landing on the customer — a fast way to generate refund requests and bad reviews. Some carriers integrate customs paperwork generation directly into their booking process, pulling product data and generating the required documentation automatically at the point of label creation, while others expect the seller to prepare and attach commercial invoices manually for every international shipment. A Bristol accessories brand shipping to both UK and EU customers found that their domestic carrier choice, which handled UK parcels perfectly well, offered only bare-bones international support requiring the seller to manually complete customs forms for every EU order — a process that was error-prone and time-consuming at any real volume. Switching international orders specifically to a carrier with integrated customs handling cut the international order processing time roughly in half and noticeably reduced the number of parcels held at customs or returned to sender for paperwork issues. The practical approach for most UK SMBs shipping to both markets is to treat domestic and international as two separate carrier decisions rather than assuming one carrier should handle everything — the carrier that is cheapest and fastest for UK parcels is not necessarily the one best set up for EU customs compliance, and using different carriers for each lane is common and often cheaper overall than forcing one carrier to do both. This is exactly the kind of blended cost picture that is hard to see without proper tracking: a seller needs to know their true average cost per parcel broken down by carrier and by destination (domestic versus EU) to make this call with real numbers rather than guesswork. AskBiz logs shipping cost per order alongside carrier and destination, so a seller can see over any time period whether their EU lane is genuinely costing more per parcel once delays, customs issues, and carrier surcharges are accounted for — and switch the carrier for that lane specifically if the numbers say so.
