DEVDIEM – your autopilot for meal allowances, home office days, and mileage reimbursement.
No more paperwork and forgotten trips: DEVDIEM largely automatically records your tax-deductible travel expenses – in the background, without you having to open the app for every trip.
HOW THE AUTOPILOT WORKS
• You define your "home zone" once (home/office).
• If you leave it, DEVDIEM automatically starts a business trip.
• Back in your home zone, the trip is saved as a complete draft – you only need to add the client and purpose.
WHAT DEVDIEM CALCULATES FOR YOU
• Meal allowances based on current flat rates – including meal reductions and arrival and departure days.
• Home office allowance – automatically derived from your working days.
• Mileage and travel costs for cars and motorcycles – using the statutory mileage allowance or your own rates.
Ready-made reports for accounting
• Clear PDF reports and DATEV/Lexware-compatible CSV exports.
• Meal allowances and travel expenses are clearly separated, with the corresponding accounting entries.
• Automatic monthly delivery upon request – for example, directly to your tax advisor.

LOCATION NOTICE
For the autopilot, DEVDIEM uses your location in the background, even when the app is closed, to detect when you leave and return to your home zone. Your location data will be used exclusively for this purpose and will not be sold to third parties. Background tracking will not occur without Autopilot enabled.
DEVDIEM does not replace tax advice. All calculations are performed carefully, but without guarantee.
