The mid-job trip to the merchant costs an unbilled hour, a delayed customer and a technician’s momentum. It happens because the van was stocked by habit rather than by list.
TL;DR Same layout in every van. Build kits by job type and grab the kit, not the parts. Weekly restock at a fixed time. Track every mid-job supply run and let the pattern tell you what to add.
Standard layout, every van
Same part, same place, every vehicle.
What this gives you
- Faster picking, because muscle memory works.
- Visual stock checks. An empty slot is visible in a second.
- Any technician can work from any van without hunting.
- Faster restocking, because the restocker knows where everything goes.
How to set it up
- Group parts by how they are used, not by supplier or type.
- Most-used items at waist height, nearest the doors.
- Label every location, on the shelf not on the box.
- Photograph the finished layout.
- Put the photo in every van as the reference for restocking.
The photograph is the standard. It is faster than a written list and it makes a wrong-looking van obvious.
Kit-based job preparation
Build kits by job type and grab the kit.
Boiler service kit: filters, seals, sealant, cleaning materials, test strips, replacement washers, thermal paste, cable ties, disposal bags.
Emergency leak kit: compression fittings in the four common sizes, pipe cutters, repair clamps, PTFE, absorbent pads, temporary shut-off.
Why kits beat picking individual parts
- One decision instead of twelve.
- Nothing forgotten, because completeness is checked once when packing.
- Faster preparation, which matters most on emergency dispatch.
- Restocking is checking the kit, not auditing the whole van.
Pre-pack the emergency kits and seal them. An emergency callout should be a grab-and-go, not a rummage.
Build the list from data, not memory
Pull twelve months of parts usage, sorted by frequency.
Then
- The top items by frequency go on every van, in quantity.
- The next band goes on one van or in the store.
- The long tail is ordered per job.
Sort by frequency, not by cost. An expensive part used twice a year is not a stocking problem. A cheap part used daily is.
Segment by technician if the work differs. A commercial-focused van needs different stock from a domestic one, and forcing one list on both means both are wrong.
Weekly restock
Fixed time, fixed person, every week.
Why fixed
- It happens, rather than being deferred.
- One supplier trip covers all vans.
- Technicians know when to flag shortages.
- The person doing it gets fast at it.
The process
- Technicians flag shortages during the week, in the app, one tap.
- Restocker consolidates into one order.
- Single collection or delivery.
- Vans restocked to the standard layout.
- Discrepancies noted, not investigated in the moment.
Friday afternoon or Monday morning. Pick one and hold it.
Track mid-job supply runs
This is the metric that drives every improvement here.
Log each one
- Which job.
- What part.
- How long it took.
- Why it was not on the van.
The reasons cluster fast
| Reason | Fix |
|---|---|
| Not on the stock list | Add it |
| On the list but run out | Raise the quantity or the restock frequency |
| Wrong size stocked | Adjust the range |
| Genuinely unusual part | Correct as is, no change needed |
| Poor job scoping | Fix the intake form, not the stock |
The last one is common and often misdiagnosed as a stock problem. If nobody asked what size the fitting was during booking, no stock list would have helped.
What to hold and what not to
Hold
- High-frequency items, generously.
- Consumables. Cheap, and running out stops work.
- Everything in the emergency kits.
- Common sizes across the range, not just the most common one.
Do not hold
- Anything with a shelf life you cannot use in time.
- Expensive low-frequency items, unless downtime cost justifies it.
- Superseded items.
- Anything you have not used in twelve months.
Audit for the last category annually. Vans accumulate parts that stopped being relevant two product generations ago.
Managing the cost
Standardised stock across several vans increases total holding. Be deliberate about it.
Control it by
- Right-sizing quantities to a week of usage, not a month.
- Consolidating suppliers for better terms on the volume you now know precisely.
- Reviewing quantities quarterly against real usage.
- Removing the long tail from the vans to a central store.
Compare it against the cost of the trips. An unbilled hour plus a delayed customer, per trip, several times a week, is nearly always more than the extra stock value.
Measure it
- Mid-job supply runs per week. The headline.
- First-time fix rate, which rises directly with correct stock.
- Stock value per van, which should be stable rather than growing.
- Time spent restocking per week.
- Stockouts on listed items, which should approach zero.
Log every mid-job supply run for two weeks with the reason attached. That list is the specification for your van stock, and it is more accurate than any list built from memory.
