Single-carrier shipping is the most common and most expensive logistics mistake SMBs make. A three-carrier strategy — primary, secondary, and specialist — reduces per-parcel cost by 15-25%, eliminates service risk, and gives you genuine negotiating leverage. AskBiz automates carrier routing so the right carrier is selected for every order without manual intervention.

The Carrier Failure That Wiped Out a Week's Revenue#
In November 2022, Evri (then Hermes) experienced a significant network disruption during peak season. Businesses that relied exclusively on Evri for their shipping had no fallback — their parcels sat in depots for 5-10 days during the most commercially important period of the year. Customer complaints flooded in. Orders were cancelled. Refunds were issued. Negative reviews accumulated. The businesses that came through this relatively unscathed were the ones that had a second carrier set up and could redirect their volume to DPD or Royal Mail within 24 hours. The businesses that didn't had a catastrophic peak season. Carrier service failures happen — not routinely, but regularly enough that single-carrier dependency is an operational risk that SMBs shouldn't accept. Beyond the service risk, single-carrier dependency is also financially suboptimal: you have no negotiating leverage, you can't route orders to the cheapest carrier for each shipment profile, and you can't benchmark whether your carrier is offering competitive rates.
The Three-Carrier Model: Structure and Logic#
A practical multi-carrier strategy for most UK SMBs is built around three carriers with defined roles. Primary carrier: your highest-volume carrier, handling the bulk of your standard shipments. You have a negotiated rate with them, your systems are fully integrated, and your team knows their collection times and cut-offs. This is typically DPD or Evri for most SMBs depending on service level requirements. Secondary carrier: a carrier that handles overflow (when your primary is at capacity), specific geographic zones (remote areas where your primary charges surcharges), or specific service types (next-day guarantee where your primary only offers standard). Royal Mail is a common secondary for most SMBs because of their geographic reach and absence of remote area surcharges. Specialist carrier: a carrier for specific needs — Parcelforce for heavyweight parcels, a same-day courier for urgent local deliveries, DHL for international shipments. This carrier handles a small proportion of volume but is essential for specific use cases. AskBiz's carrier routing engine assigns each order to the appropriate carrier automatically based on the rules you configure.
The Cost Saving: Where the 15-25% Comes From#
The per-parcel cost saving from a multi-carrier strategy comes from routing each shipment to the cheapest carrier that meets the service requirement. Example: for a 500g parcel going to a standard mainland UK address on a 2-day service, Evri might cost £3.20 vs Royal Mail Tracked 48 at £3.80. Evri wins. For a 500g parcel going to a remote Scottish Highlands address, Evri adds an £8 surcharge — total £11.20. Royal Mail Tracked 48 goes to the same address for £3.80. Royal Mail wins by £7.40. For a 2kg next-day B2B parcel, DPD at £8.20 is better than Evri at £7.90 because DPD's service reliability is significantly higher for B2B. Running all orders through one carrier means you're using the wrong carrier for a significant proportion of your shipments. The 15-25% blended saving comes from consistently routing each shipment to its cheapest appropriate option. On a £10,000/month carrier spend, that's £1,500-£2,500/month saved.
Setting Up the Carrier Routing Rules#
Carrier routing rules determine which carrier handles which order. The rules should be based on: delivery service level (next-day: carrier A; 48-hour: carrier B), destination postcode (standard mainland: carrier A primary; remote area: carrier C for economy, carrier B for next-day), parcel weight and dimensions (under 2kg: carrier A; 2-10kg: carrier B; pallet: carrier D), product type (dangerous goods: only approved dangerous goods carriers), and customer segment (premium B2B accounts: always carrier A for reliability; standard consumer: lowest cost meeting service level). AskBiz lets you configure these rules in a routing decision tree that executes automatically at order processing. The result: every order is assigned to the right carrier without a dispatcher making a manual decision. The routing logic is visible and editable — when carrier pricing changes or you add a new carrier, you update the rules and the routing adjusts immediately for all subsequent orders.
Negotiating Leverage: The Commercial Power of Multi-Carrier#
When you depend entirely on one carrier and they know it, your negotiating position in rate discussions is weak. When you have two carriers processing significant volume and are clearly capable of routing more volume to either one, your negotiating position is completely different. Carrier account managers respond well to "we're currently splitting volume 70/30 between you and [competitor], and we're reviewing our allocation in Q2 — what can you do on rate to increase your share?" This is a genuine conversation that produces real outcomes. The carrier wants to increase its share of your volume; you want a better rate. Both parties have something to trade. SMBs that run this process systematically — getting competing rate proposals before each quarterly carrier review — consistently achieve 8-15% better rates than businesses that don't threaten to move volume. AskBiz prepares a Carrier Volume Report before each review showing your split by carrier, service type, and geography — the exact data carriers need to respond with a meaningful counter-offer.
The Operational Complexity of Multi-Carrier: How to Manage It#
The main argument against multi-carrier strategy is operational complexity: multiple label formats, multiple collection windows, multiple invoice reconciliation processes, and multiple tracking systems. This was a legitimate barrier when carrier integration required significant technical work. Modern carrier management platforms — including AskBiz — solve this problem. A single integration point with the AskBiz platform gives you access to all carrier APIs simultaneously. Labels for all carriers print in a standardised format from one interface. Tracking events from all carriers are consolidated in one dashboard. Invoices from all carriers are imported and reconciled against bookings automatically. The operational overhead of a three-carrier strategy with AskBiz is genuinely minimal compared to single-carrier, probably 20-30 minutes per week of additional administrative time.
Building Your Carrier Portfolio Gradually#
If you currently use one carrier, don't try to implement a full three-carrier strategy simultaneously. Start by adding one secondary carrier and letting it handle a defined subset of your volume for 90 days. Choose a defined subset — remote area deliveries, or economy service orders — where the routing rule is simple and the benefit is clear. After 90 days, review: is the secondary carrier performing as expected? Is the cost saving materialising? Are there operational issues to resolve? Once the two-carrier model is working smoothly, add the specialist carrier for specific use cases. This graduated approach avoids the operational disruption of a big-bang multi-carrier implementation and lets you build confidence in the routing system progressively.
Three Carriers Means Three Times the Leverage#
The strategic value of a multi-carrier portfolio compounds over time: better negotiating leverage means lower rates, which improves your margin or allows competitive delivery pricing. Carrier performance competition means both carriers maintain service quality to retain your volume. Operational resilience means a service disruption at one carrier is a manageable inconvenience, not a business crisis. AskBiz supports the full multi-carrier journey — from initial carrier API setup through routing rule configuration, carrier performance tracking, and cost comparison reporting that keeps your carrier mix optimised as your business evolves.
