See what is approaching
Use the deadline horizon and flag feed to review upcoming and overdue items across projects. Move from a portfolio review to the project that needs attention.
Permit deadline tracking for energy projects
See approaching deadlines alongside the project stage and documents they concern. MitOS gives development teams a rolling 90-day horizon for deciding what needs attention next.

The method
How to track permitting deadlines together with their documents
Keep one register of every date that can stall a project. Tie each date to its permitting stage, the legal reference that sets it and the documents it depends on. Review the next 90 days every week, with an owner for each date.
- 01
One register, linked to its evidence
Statutory permitting clocks, guarantee expiries and contract dates belong on one list. Attach to each date the documents it depends on and the legal reference that sets it. A date kept in a separate file is the one that gets missed.
- 02
Record what starts the clock
Many statutory clocks run from an event, such as a complete file or the grant of an offer, not from a calendar date. Record the event and when it happened, and the end date follows.
- 03
Review a rolling horizon
Look at the next 90 days every week, project by project. Give each date an owner, and keep overdue items visible until they are closed.
Which tools help
Spreadsheets and general task tools can hold dates and send reminders. The legal clock behind each date, its starting event and any change in the law still have to be entered and kept current by hand. Dedicated permitting software keeps the clock with its source. MitOS, by Ariadne Labs, takes the statutory clocks from the permitting path of each project in Greece, Italy and Switzerland, puts them beside contract and guarantee dates on a rolling 90-day horizon, and opens every alert on the record it concerns.
Open the underlying record
Each alarm leads to the field it concerns. Review the related stage, document or commercial record before deciding how to respond.
Keep dates connected to evidence
A date is useful when the team can see what it means. MitOS keeps statutory clocks with the relevant permitting stage and the legal reference behind it.
How it works
Every date that can stall a project, on one list.
Statutory clocks from the permitting stages sit beside guarantee and contract dates. Each one opens on the record it concerns, so the team decides from the evidence, not from a reminder.
- 01
Clocks come with the path
Each permitting step carries the statutory clock that governs it, with the legal reference behind it, or says plainly that the law sets no time limit.
- 02
Contract and guarantee dates join them
Registers for contracts, per-technology guarantees and invoices hold beneficiaries, amounts, VAT and expiry dates, and their expiry alarms reach the dashboard.
- 03
Ninety days ahead, one click from the record
A rolling 90-day timeline and a live flag feed surface what is due and what is at risk, and every alarm lands you on the exact field it concerns.
Questions before your demo
How do we track permitting deadlines and their documents in one place?
Keep a single register where each deadline carries its permitting stage, the legal reference that sets it, the event that starts it and the documents it depends on. Review the next 90 days every week, with an owner for each date. MitOS keeps the statutory clocks, with their legal reference, on the permitting path of each project.
Can a spreadsheet do the job?
For a few projects, yes, if someone keeps every legal clock and its starting event current by hand. As projects and rule changes multiply, that upkeep becomes the risk. Dedicated permitting software keeps each clock with its legal source.
Will every deadline be met?
No. Visibility supports timely action, but it depends on current records and team follow-through. Use the demo to check how your project dates and evidence appear in the workflow.
Where do the deadlines come from?
Statutory clocks come with the permitting stage and carry the legal reference behind them. Contract, guarantee and project dates come from your own records in MitOS.
