The short answer
A spreadsheet is enough while one person holds the whole picture. It stops being enough when two people need it, when the same periods repeat every month, or when you need to know what is waiting on a client.
What a deadline tracker has to do
- Show every client's next date in one place.
- Create the periods itself, so each month is not typed by hand.
- Move a date off a weekend or holiday by a rule, not by memory.
- Name an owner for every piece of work.
- Show status: not started, waiting on the client, done.
- Link the documents that are missing or received.
- Keep history, so you can see what happened and when.
Where a spreadsheet works
A spreadsheet works when the firm is small, one person does the planning, the services are few and the same for everyone, and clients send documents by email without much chasing. It is free, everyone knows it, and it can be changed in a minute. That is a real advantage, and there is no need to leave it early.
Where it breaks
Signs it is time to move
| What you see | Why it hurts |
|---|---|
| Two people edit the same sheet | Overwritten cells and stale copies by email |
| You retype the same dates every month | Time lost, and a typo becomes a missed date |
| You cannot say what is waiting on a client | The status lives in inboxes, not in the sheet |
| A date moves and nobody notices | There is no rule behind the date, only a number |
| A colleague is away | The knowledge sat in one head |
A simple test
Imagine you are out for a week. Could a colleague open the file and tell, in ten minutes, what is due, what is late and what is waiting on clients? If the honest answer is no, the sheet is already carrying more than it can hold.
Moving without losing a week
- List your clients and services the way you would explain them to a new colleague.
- Export the sheet as a CSV. One row per client is enough to begin.
- Map the columns, preview the result and fix the rejected rows before you confirm anything.
- Describe each service once as a recurring series with its deadline rule and an owner.
- Run both side by side for one period, then retire the sheet.
Keep the spreadsheet for what it is good at
Calculations, one-off analysis and quick lists still belong in a spreadsheet. The point is not to ban it. It is to stop using it as the system that remembers your deadlines, a job it does by accident.
How this works in Claister
- Clients import from a CSV with column mapping, a preview and a report of rejected rows.
- Recurring work is a series that creates every period for every client, in a client by task matrix, with weekend adjustments and a preview of the next three periods.
- Spreadsheets stay available as workbooks: open an XLSX file, edit with Excel formulas across sheets, and export back to XLSX.

Questions
It handles tasks well. The gaps are the same as in a spreadsheet: periods that repeat by rule, documents waiting on clients and history on each client.
There is no fixed number. The signs in the table matter more than the count: shared editing, retyping, hidden status.
Yes. Start with a few clients and one service, run one period, then add the rest in groups.
