When a spreadsheet is enough
A handful of projects in one country, one person who owns the file, and few rule changes. Keep it, and give every deadline its legal source and its starting event.
MitOS vs spreadsheets for energy permitting
A spreadsheet can track a few projects well, as long as one person keeps every legal clock and its starting event current by hand. As projects and rule changes multiply, that upkeep becomes the risk. Here is where the two differ.

Side by side
What changes when permitting moves out of the spreadsheet
| Task | Spreadsheet | MitOS |
|---|---|---|
| The law behind each requirement | Typed in and kept current by hand | Every requirement carries the article of law behind it, cited and clickable |
| When a project fact changes | Someone rebuilds the list | Change one fact and the whole path re-derives |
| Deadlines | Dates in cells; reminders only if someone sets them | Statutory clocks with their legal reference, on a rolling 90-day timeline with a live flag feed |
| Guarantees and contracts | Separate sheets, checked when someone remembers | On the same record as the permits, with expiry alarms that reach the dashboard |
| Portfolio status | Rebuilt from separate files | Computed from real document and stage state, not self-declared |
| Documents | Links to folders | Registered with type, revision and issuer, with a data room view for outside parties |
| Evidence for lenders and buyers | Assembled by hand for each request | PDF and Word exports with a tamper-evident fingerprint |
| Where the data lives | Wherever the file is saved | A desktop edition on your own database, or a cloud workspace for teams |
| Cost to start | None: it is already on every laptop | A licence, priced on request |
When it stops being enough
Several jurisdictions, a team instead of one owner, guarantees and contracts tied to permit dates, or lenders asking for evidence. Then the upkeep, not the tool, becomes the risk.
Judge it on your own project
Bring a real project to the demo. We walk through how its permits, documents and dates would sit in MitOS, so the team can decide on its own data.
Questions before your demo
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.
Which countries' law is built in?
Greek, Italian and Swiss law, cited to the article. Your team confirms how it applies to each specific project.
Can our data stay on our own servers?
Yes. The desktop edition runs on a local or network database, and your data never leaves your premises. A cloud edition is available for teams.
