The 6 Logistics KPIs Every SMB Should Track (and How to Pull Them Automatically)
Revenue is a vanity metric if your logistics costs are invisible. The 6 KPIs that actually tell you whether your delivery operation is profitable — cost per delivery, on-time rate, failed attempt rate, WISMO rate, return rate, and cost as % of revenue — can all be pulled automatically from AskBiz without manual data wrangling.

The Business That Was "Growing" While Losing Money on Every Delivery#
A UK health supplement brand was growing at 35% year-on-year. Revenue was up. The team was excited. But gross margin was quietly declining by 2-3 percentage points annually. The founder eventually traced the problem to their logistics operation — specifically, their cost per delivery had increased from £6.80 to £9.20 over three years as carrier rates rose, return rates crept up, and packaging costs increased. They'd been so focused on top-line growth metrics that they'd entirely missed the deterioration in their delivery economics. The fix required three months of data work to establish baselines on six metrics they'd never systematically tracked. Once those baselines were in place, they identified four specific cost drivers, fixed them over two quarters, and recovered 2.8 percentage points of gross margin. The lesson: you can't manage what you don't measure, and most SMBs are not measuring the right logistics metrics. These are the six that matter.
KPI 1: Cost Per Delivery#
Cost per delivery is the single most important logistics KPI — the total cost of getting one order to one customer, including carrier fee, packaging, pick-and-pack labour, failed attempt costs (averaged across the delivery volume), and insurance. It should be calculated weekly and tracked as a trend. If your cost per delivery is rising faster than your delivery pricing, you have a margin compression problem that will compound. Target: know your cost per delivery to the penny, segmented by carrier and by product category. AskBiz calculates this automatically from carrier invoice data, packaging cost allocations, and labour cost inputs, and presents it as a weekly metric with trend analysis. Most businesses that set up this KPI for the first time discover their actual cost is 20-35% higher than they assumed.
KPI 2: On-Time Delivery Rate#
On-time delivery rate measures the percentage of orders delivered by or before the delivery date you promised the customer at checkout. This is distinct from the carrier's own on-time metric (which measures whether they delivered within their service window) — yours measures whether you delivered what you promised. A carrier delivering within their "1-3 day" window doesn't mean you delivered within the "2-day" window you showed the customer. Target: 95%+ on-time. Below 90% is a customer satisfaction and retention problem. Track by carrier to identify which carrier is driving poor on-time performance, and by product category to identify where pick-and-pack delays (not carrier delays) are the issue. AskBiz cross-references your promised delivery date at checkout against the carrier's actual delivery event to calculate your true on-time rate.
KPI 3: Failed First Attempt Rate#
Failed first attempt rate measures the percentage of deliveries that require more than one delivery attempt before the parcel is successfully received. Industry average for UK B2C is 18-23%. Best-in-class SMBs operate below 8%. Every failed attempt adds cost (re-delivery fees, customer service contacts) and damages customer satisfaction. Track by carrier — failure rates vary significantly between DPD (typically 8-12%), Royal Mail (12-18%), and Evri (18-28% for some route profiles). Also track by geographic area to identify where proactive communication improvements would have the most impact. AskBiz calculates your failed first attempt rate from carrier tracking event data and shows it by carrier and postcode area on a weekly dashboard.
KPI 4: WISMO Rate#
WISMO rate (Where Is My Order contacts per 100 orders) measures the volume of customer contacts generated by delivery uncertainty. Industry benchmark: 5-8 WISMO contacts per 100 orders. Best-in-class with proactive tracking communications: 2-3 per 100. Each WISMO contact costs £3.50-£5.00 in customer service time. At 500 weekly orders, the difference between a 6% WISMO rate (30 contacts/week, £120-£150/week cost) and a 2% rate (10 contacts/week, £40-£50/week cost) is £80-£100/week — or £4,000-£5,000/year. AskBiz calculates WISMO rate by tagging customer service tickets with delivery-related classifications and correlating them against your delivery volume. The dashboard shows WISMO rate by week, by carrier, and by product category, so you can identify where proactive tracking communications would have the biggest impact.
KPI 5: Return Rate by Product and Category#
Return rate is typically tracked at the overall level ("we have a 12% return rate") but the insight lives at the product and category level. An overall 12% return rate might comprise a 4% rate on Category A and a 28% rate on Category B. Fixing Category B's returns issue — whether through better product photography, size guide improvement, or packaging — has a dramatically larger impact than any operational improvement. AskBiz calculates return rate by SKU, by category, by origin country (to identify supplier quality issues), and by reason code (size, wrong item, damaged, changed mind). The SKU-level return rate report is the highest-value returns intelligence report you can generate — and it's something most SMBs have never produced.
KPI 6: Delivery Cost as a Percentage of Revenue#
Delivery cost as a percentage of revenue is the macro metric that tells you whether your logistics operation is within commercially sustainable bounds. Industry benchmarks vary by sector: for fashion and beauty e-commerce, 8-12% is typical. For bulky goods (furniture, gardening equipment), 15-20% is common. For trade B2B delivery, 3-6% is typical. If your delivery cost as a percentage of revenue is above sector norms, you have a structural problem — either your delivery pricing is too low, your carrier costs are too high, or your product mix generates too many expensive deliveries. AskBiz calculates this metric weekly, with trend analysis and sector benchmark comparison, so you're alerted when your delivery economics are drifting out of the acceptable range.
Pulling All Six Metrics Automatically#
The barrier to tracking these six KPIs for most SMBs isn't willingness — it's the manual data work required to compile them. Carrier invoices in one system, sales data in another, customer service ticket data in a third. Pulling these together weekly without automation requires 4-6 hours of analyst time and is almost never done consistently. AskBiz integrates with your carrier accounts, your POS or e-commerce platform, your Xero accounts, and your customer service platform (Zendesk, Freshdesk, or email) to calculate all six KPIs automatically and present them in a single weekly dashboard. Setup takes approximately 3 hours. After that, the dashboard updates without manual intervention, and you get a weekly logistics health report delivered to your inbox every Monday morning. The businesses that track these six metrics consistently make 2-4 better logistics decisions per quarter than those that don't — and those better decisions compound into significant commercial advantage.
