May ask, who do you use for tacho analysis and how much do you pay? I use Novadata for analogue.
I use Descartes Smart Analysis, costs are 25p per driving day per driver for digital and 35p for analogue, no charge for VU or setup.
For small companies I use Tachomaster, £1 per active driver per week and 50p per active vehicle.
For larger companies I use pitstop from rocksandcomputers.co.uk purchased outright. Remember you will need to do back-ups of data.
Tachomaster…love it, nice graphics, good infringement letters, worker calenders etc. Does everything I need though I’ve only limited experience of other systems.
