Nobody switches couriers after one bad delivery. They switch after the fourth conversation that goes nowhere, and usually several months later than they should have.
The delay is understandable. Switching feels risky, the current provider knows your routes, and there’s always a reasonable explanation for the last failure. But the cost of staying is paid by your customers, who don’t distinguish between your business and the van outside.
Here are seven signs it’s the provider rather than a bad week, plus how to switch without creating the disruption you’re worried about. If you’re starting from scratch rather than replacing someone, how to choose a courier service for your business covers the selection criteria directly.
The Bottom Line
- One failure is an incident. The same failure three times is a process, and processes don’t improve because you complained.
- A courier that can’t state its on-time percentage and definition isn’t measuring it, which means it can’t fix it either.
- Failed deliveries cost around $17.20 each directly, and one analysis found roughly 70% of shoppers won’t return after a single failure.
- Switch during your quietest month, run both providers in parallel, and move your hardest route last.
Lower your delivery costs by 23%
How we reduce costs:
- No delivery vehicle expenses
- Optimized local routes
- Pay-per-delivery model
- Average 23% delivery cost reduction
1. Late deliveries have become a pattern, not an incident
Traffic happens. A pattern is different: the same route late every Friday, the same account calling you every week, a drift from “occasionally late” to “usually late.”
The diagnostic question isn’t whether they’re late. It’s whether anyone there knows they’re late. Ask for your on-time percentage over the last three months and the definition being used. A provider that measures will produce a number. One that doesn’t will produce an apology.
For reference, across Metrobi’s driver network 93% of couriers arrive within 15 minutes of the delivery request and 99.3% of courier requests are fulfilled. The specific figures matter less than the fact that they exist and are tracked.
2. Goods arrive damaged, spoiled or wrong
Damage tells you about handling, and handling is cultural. A courier whose drivers treat a tray of pastries like a parcel will keep doing that, because nothing in the process distinguishes between them.
Watch for the pattern across three things: breakage, temperature failures on warm days, and deliveries left somewhere the goods shouldn’t be. Then ask what the handling instructions actually look like from the driver’s side. If the answer is “the address and the customer name,” you’ve found the problem.
Also check your per-shipment insurance limit while you’re there. For catering and wholesale orders it’s frequently lower than the value of a single delivery.
3. Nobody can tell you what went wrong
This is the strongest signal on the list, because it predicts the future rather than describing the past.
When a delivery fails, you should be able to find out within minutes what happened, who was involved and what’s being done. If instead you get an excuse, a call-back that doesn’t come, or a ticket number, the provider has no operational visibility into its own network, and a provider that can’t see a failure cannot prevent the next one.
Judge three things: how you reach a person, how quickly, and whether that person can act. A call centre that logs a ticket is not support. Metrobi’s support team runs 24/7 and averages a 76-second response to a support message, with phone calls transferred directly to someone who can act; Software Advice has named it the best customer support in the courier and logistics industry.
4. You are the tracking system
If customers ask you where their order is and you have to call a dispatcher, your courier has outsourced its visibility problem to you.
The 2026 baseline is a customer-visible tracking link, automated dispatch and delivery notifications, an accurate ETA, and timestamped photo proof of delivery. One industry review puts the share of customers expecting real-time tracking above 90% (CEO Monthly), so this isn’t a premium feature any more.
The cost of lacking it shows up in failures. A Loqate study put the average cost of a failed delivery at $17.20 per order (via PR Newswire), and one analysis of missed attempts reports around 70% of shoppers won’t return after a single failure (DeliverLoop). What to require and how to test it before signing is in technology in courier services.
5. They can’t absorb your busy week
Capacity is where small couriers and growing businesses part company, usually in the worst possible week.
The signs are easy to spot in hindsight: stops refused in December, a cap appearing on daily volume, windows widening during your peak, or being asked to split a day’s deliveries across two days. If your peaks are Valentine’s Day, Mother’s Day or Thanksgiving week, those are the weeks that carry your year, and a provider who can’t cover them is capping your revenue, not just inconveniencing you.
Ask the direct question before the season: what happens if I triple my stops for one week? Specificity in the answer is the whole test.
6. The invoice keeps surprising you
A quote of $12 per delivery that arrives as something else means the pricing structure was never explained.
Go through one month’s invoice line by line and find the fuel surcharge, the wait-time charges, the oversize fees and the redelivery charges. Then ask for each to be explained in advance. A well-run courier produces that schedule without hesitation; this is the same legibility test described in what makes a good courier service.
This is not a trivial sum. Last-mile delivery now accounts for roughly 53% of total shipping cost, with the average standard delivery costing about $10.10 to perform while customers are typically charged $8.08 (SmartRoutes last-mile statistics). Opaque pricing on your largest controllable cost is a reason to move on its own.
7. It’s a different driver every time, and none of them learn
A driver on their fifth week of your route knows the café that takes deliveries through the side alley and which boxes go in the walk-in. A different stranger every day knows none of it, and every one of those gaps becomes a phone call to you.
Ask whether driver continuity is possible at all. If the honest answer is no, the service has a ceiling you’ll keep hitting. On Metrobi, businesses add top-performing drivers to a preferred network so those drivers get priority on their future jobs, and can ban drivers they’d rather not work with again.
Driver continuity is also one of the main reasons a local operator tends to outperform a national network for same-metro work, as set out in the benefits of a local courier service.
Fix it once before you switch
Not every problem is a reason to leave. Three are worth one serious conversation first:
- A single bad route. Sometimes it’s one driver or one badly sequenced run, and it’s fixable in a week.
- Unclear expectations. If you never stated the time window in writing, the courier may be hitting a different target than the one in your head.
- Bad inputs. Wrong addresses, missing phone numbers and optimistic service times produce failures that look like courier problems. That side is yours, and it’s covered in efficient delivery planning.
Have the conversation, state the specific standard you need, and give it three weeks. If nothing measurable changes, you’ve learned something more useful than any sales pitch.
How to switch courier services without disruption
Five steps that keep the risk small:
- Switch in your quietest month. Never during a peak, and never during a product launch.
- Run both in parallel. Give the new provider a small, representative set of routes while the incumbent keeps the rest.
- Move your hardest route last. The tricky dock, the fussy account, the tight window. Those go once the new courier has proven itself on the easy work.
- Measure the same things for both. On-time percentage against your promised window, first-attempt success, and cost per completed delivery. In the US roughly 97.2% of first attempts succeed and strong operations target a 90%-plus first-attempt rate (SmartRoutes delivery success rates).
- Keep the notes. Address quirks, access instructions and contact preferences are your asset, not the courier’s. Export them before you leave.
If the review raises a bigger question (whether to use a courier at all rather than running your own vehicles) that comparison is in outsourcing delivery services.
Frequently asked questions
When should I switch courier services?
When the same failure recurs after you’ve raised it, when nobody can explain what went wrong, or when the provider’s capacity caps your busy weeks. One bad delivery isn’t a reason; an unchanged pattern is.
How do I switch couriers without disrupting customers?
Switch in a quiet month, run both providers in parallel on different routes, give the new courier the straightforward routes first, and move your most difficult route only once it has proven itself.
What should I measure to compare two couriers?
On-time percentage against the window you promised your customer, first-attempt success rate, and cost per completed delivery including all surcharges. Those three settle most comparisons.
Is it worth switching couriers over price alone?
Rarely. Reliability failures cost more than rate differences, since a failed delivery runs around $17.20 directly and risks the customer entirely. Switch on reliability; negotiate on price.
The deciding question
Ask yourself how many hours you spent last month managing your courier rather than using it. If the answer is more than a couple, you’re doing the provider’s job for them, and that’s the real cost of staying.
Then set the bar before you shop: a measured on-time rate, a named escalation path, customer-visible tracking, proof of delivery, driver continuity, and a clear fee schedule. Hold every candidate to all six.
