How to Switch Fleet Management Software Without Losing Data
Published
The short version
- Switching is much less scary if you plan it. The main job is making sure you can get your records out of the old system before you leave it.
- Export first, and check the export. Don't cancel anything until you've seen the file and opened it.
- Run the old and new side by side for a short while, then move everyone over.
- Keep your old records safe. You may need them for years.
- If you're coming from a spreadsheet, the same steps apply.
Why people put off switching
Most people stay with a system they don't like because they're worried about their records. Years of service history, costs and dates. What if it vanishes?
That's a fair worry. The good news is that it's mostly avoidable with a bit of planning. The bad news is that it's a lot easier to plan before you've cancelled than after.
Step 1: Decide what you actually need to keep
Not everything's worth moving. Sit down and list what matters:
- Vehicle details, including registrations.
- Key dates, such as MOT, tax and servicing.
- Maintenance history and costs.
- Records of checks and faults.
Some of that you'll want in the new system. Some of it you'll just want to keep safe in a file.
Step 2: Find out how to get your data out
Check this before anything else. Look at what the old system can export, in what format and whether it includes everything or just part of it. If it's not obvious, ask the supplier, in writing if you can.
If you can't get your records out, that's important to know now. It might change when and how you leave.
Step 3: Export it and check the file
Don't just click "export" and assume it's fine. Open the file. Check it's complete, the dates look right and the costs add up. Pick a couple of vans and compare the file against what you know.
Then save a copy somewhere safe, away from the system you're leaving.
Step 4: Keep your old records
Think about how long you'll need them. GOV.UK says that, for a limited company, you must generally keep company and accounting records for 6 years from the end of the last company financial year they relate to, and sometimes longer. The detail is on GOV.UK's guide to company and accounting records.
If you're VAT-registered, HMRC's VAT record keeping notice (700/21) says that, generally, you must keep your business records for VAT purposes for at least 6 years.
I'm not an accountant, so check with yours what applies to you. But if some of your fleet costs sit in the old system, make sure you've got a copy you can read in a few years' time.
Step 5: Set up the new system with a couple of vans
Don't move the whole fleet in one go. Start with one or two vans and check everything works.
Do the dates match? GOV.UK says you can be fined up to £1,000 for driving without a valid MOT. That's a maximum, not a typical fine, but it's a good reason to double-check each MOT date as you move it across, and not trust that it copied correctly.
Step 6: Run both for a short time
For a few weeks, keep the old system going alongside the new one. It's a bit of extra work. But if something has gone astray, you'll find it while you've still got the old records to compare against.
Keep it short, though. Two systems for months means two sets of records, which is how you end up in the very mess you were trying to leave.
Step 7: Get your drivers on board
The best system in the world fails if drivers don't use it. Show them how it works, keep it simple and tell them why you're changing. A five-minute demo in the yard usually beats a long email.
Step 8: Tell your accountant
If you export costs for your accountant, let them know what's changing. Check the new export works with the software they use before you rely on it. Otherwise you'll find out at the worst time.
Step 9: Cancel the old one last
Only cancel when you've seen your exported records, you've checked them, the new system is working and your drivers are using it. Check the notice period, too, so you don't pay for longer than you need to.
If you're coming from a spreadsheet
The same steps apply, and it's usually easier, because you already hold the file. Save a copy of the sheet before you start, and keep it. If you want to know whether it's time to move on from it, What Is Fleet Management Software and Do You Need It? is a good place to start.
Choosing a system you can leave
The best time to think about switching is before you've signed up. When you're comparing products, ask how data comes out, in what format and what happens to it when you leave. Fleet Management App Features Every Small Trade Business Needs is a good guide to what to look for.
If you're moving off an older system, there's a more detailed checklist in Switching From a Legacy Fleet System: A Migration Checklist.
Where FleetGuv fits
FleetGuv is in beta, and it's built for small UK limited companies with small fleets. It's hardware-free: vehicle checks on a phone, with faults sent straight to the manager, a maintenance log for each van and MOT details pulled from DVSA. There's a CSV export of costs for Xero and QuickBooks.
If you're thinking of moving over, my advice is the same as for any new system: try it on a couple of vans first. There's a free trial and you don't need a card.
The Governor, our foreman character, says never throw out the old paperwork until the new system's proved itself. For once, I agree with him.
You can try FleetGuv free. For the full picture, my guide is Fleet Management Software for Small Business: The Complete Guide (2026).
The bottom line
Switching is a job, not a disaster. Find out how to get your data out, export it, check it, keep a copy and move over a couple of vans at a time. Cancel the old system last.
Do it that way and you won't lose your records. You'll just have them somewhere better.
