Route optimisation isn't just for logistics giants. A 5-van SMB fleet running optimised routes vs unplanned routes can save £14,000/year in fuel alone, plus cut overtime and improve delivery windows. AskBiz connects route data with delivery cost tracking so you measure the savings continuously.

Five Vans, £14,000 a Year Left on the Table#
If you run a small delivery fleet — let's say five Transit vans doing local and regional deliveries — and your drivers are planning their own routes each morning, you're almost certainly burning more fuel than you need to. The industry benchmark is blunt: unoptimised routes in a 5-vehicle fleet typically add 20-28% to total distance driven compared to algorithmically planned routes. At current diesel prices of roughly 150p/litre, and assuming each van does 180 miles a day on average, that excess mileage costs around £2,800 per van per year — or £14,000 across the fleet. That's before you factor in driver overtime when routes run long, wear-and-tear costs, and the customer satisfaction impact of late deliveries. Most SMB owners who hear this are sceptical. They'll say their drivers know the area better than any app. That's often true for individual road knowledge. But no human brain can simultaneously optimise for 35 delivery stops, traffic patterns, time windows, vehicle load capacity, and return trip efficiency. That's where software has a clear, measurable advantage.
What Route Optimisation Software Actually Does#
Modern route optimisation tools take your delivery manifest — typically exported from your order management system or POS — and run it through an algorithm that sequences stops to minimise total distance while respecting time windows, vehicle capacity, and driver break requirements. The better tools also ingest real-time traffic data and reroute dynamically when there's an incident on the planned route. For a 5-van fleet, you don't need enterprise logistics software. Tools like Circuit, OptimoRoute, or the route planning module within AskBiz's delivery management suite are priced for SMBs and can be operational in an afternoon. The optimisation process for a typical day's manifest takes about 90 seconds. Drivers get their routes on their phones as a turn-by-turn sequence, often integrated with Google Maps or Waze for navigation. The dispatcher sees a live map showing where all five vans are and whether they're running on schedule. The difference from the old "driver plans their own route" model is immediately visible on the fuel bill.
The Real Numbers: A West Midlands Trade Supplier Case Study#
A West Midlands trade supply business with six drivers delivering to construction sites and merchants switched to route optimisation in Q1 2024. Before: their drivers were planning routes individually each morning, typically spending 20-30 minutes with a paper manifest and Google Maps. After introducing optimised routing, the results over the first three months were: average daily mileage per van dropped from 194 miles to 157 miles — a 19% reduction. Fuel costs fell from £4,200/month across the fleet to £3,390/month, saving £810/month. Driver overtime dropped from an average of 3.5 hours per driver per week to 1.1 hours, saving approximately £1,200/month in overtime costs at their £14/hour driver rate. Customer on-time delivery performance improved from 78% to 94%, which translated into measurably fewer account queries and complaints. Total annualised saving: just over £24,000. This is a slightly larger fleet than our five-van example, but the proportional savings are consistent with what you'd expect from a 5-van operation: £14,000-£18,000 per year is a realistic target.
Connecting Route Optimisation to Cost Tracking#
The frustrating thing about many route optimisation tools is that they operate in a silo. Your dispatcher knows the routes are tighter, but the fuel savings are invisible unless someone manually reconciles the fuel card statements against the theoretical improvement. AskBiz bridges this gap by connecting your route data with your fuel card transactions (compatible with Allstar, Fuel Card Services, and key supermarket fleet cards), your carrier invoices, and your Xero cost codes. You get a weekly summary showing planned route distance vs actual driven distance per vehicle, fuel cost per delivery, and total delivery cost against the previous period. When your route optimisation is working, you see it in the numbers immediately. When a driver is deviating significantly from the planned route — a common issue in the first weeks of a new system — the variance flags up and you can address it through coaching rather than blame.
Time Windows and Customer Satisfaction#
One of the underrated benefits of route optimisation is the ability to give customers accurate delivery windows. When routes are planned properly and followed consistently, your ETA predictions become reliable. Instead of "delivery between 8am and 6pm" — which is essentially useless for a B2B customer who needs to have someone on site — you can commit to "delivery between 10:30am and 12:30pm" with 90%+ accuracy. This has a direct commercial value. For trade suppliers, it means customers trust you enough to book smaller more frequent orders rather than holding large buffer stocks. For consumer delivery businesses, it's a genuine competitive differentiator. AskBiz's route tracking dashboard lets customers see a live map of their driver's location and an updated ETA — similar to what Uber Eats does, but for your own delivery fleet. Customer satisfaction scores for businesses implementing this typically improve by 15-25 percentage points in post-delivery surveys.
Getting Driver Buy-In Without Micromanaging#
The biggest practical barrier to route optimisation in SMB fleets isn't the software — it's the drivers. Experienced drivers can be resistant to being told by an algorithm that their route is wrong. They're not being awkward; they genuinely believe they know something the software doesn't. Sometimes they're right. The best approach is to frame optimisation as a tool that removes the boring planning work from their morning, not a surveillance system that monitors their every turn. Show drivers the fuel savings data. If your drivers are on a commission or bonus structure tied to deliveries completed, show them how optimised routes mean more stops completed in the same time. Give them the ability to flag route issues in the app — when a one-way street has changed or a site has restricted access, their feedback improves the algorithm. After the first month, driver resistance typically evaporates because the routes genuinely work.
The Payback Period for Route Optimisation Software#
Route optimisation software for a 5-van fleet typically costs £150-£350/month for an SMB-grade tool. At the fuel and overtime savings we've discussed, the payback period is measured in weeks, not months. The £2,800/year per vehicle fuel saving alone covers the software cost by a factor of four to five. Additional value comes from reduced vehicle wear (fewer miles = lower maintenance costs and extended vehicle life), lower insurance claims (optimised routing tends to reduce driver stress and incident rates), and the commercial value of improved delivery accuracy. If you're considering fleet expansion, route optimisation data also gives you a much cleaner picture of how far you can stretch the existing fleet before you genuinely need another vehicle. Several AskBiz users have found that optimisation delayed a van purchase by 12-18 months.
Start Measuring, Start Saving#
Route optimisation's impact is only as visible as your cost tracking allows it to be. AskBiz connects your route planning, fuel card data, and delivery cost calculations in one dashboard so you see exactly how much each improvement is worth in pounds and pence. The businesses that make the most progress are the ones who establish a clear baseline first — what does a delivery currently cost? — and then track the improvement systematically. For a 5-van fleet, the annual saving from proper route optimisation is consistently in the £12,000-£18,000 range. That's real money for an SMB, and it's sitting there waiting to be claimed.
