Does Tsuno replace your scheduling, HR or HACCP software?

No, Tsuno does not ask you to replace your scheduling software, your food safety tool, your POS or your payroll. For each area, you decide: source of truth, import with human validation, temporary duplicate, replacement over time or out of scope. Specialist tools keep their trade. Tsuno keeps the memory between them.

A Monday of setup, four tools that stay

The owner of four restaurants already uses scheduling software, a solution for temperature readings, a POS and a payroll tool. They fear that a new tool will force them to start over. At the first meeting, the four areas are laid on the table and settled one after the other: scheduling stays in its software, whose exports will be imported; readings stay in the current solution while we see how it goes; the POS and payroll do not move. Nothing is replaced that day. The only new thing is that instructions and standards, until then in people's heads and in messages, are written down once.

Why the question of replacement is badly framed

• Every vendor has a trade. Vendors such as Skello or Combo serve real needs, with their own customers; their exact features are described on their sites. The point is not to compete with them on that trade.
• The gap sits between the tools. A schedule does not know which skill a task requires. A reading does not say why an instruction changed. That link is rarely held by anyone.
• Replacing everything at once is risky. You lose the history, you tie up the managers, you stop serving during the migration.
• Keeping without deciding creates duplicates. Two tools holding the same information end up contradicting each other.

The five options, area by area

Option	What it means	Example case
Tsuno as source of truth	The information lives in Tsuno	Standards, procedures, checklists
Import with human validation	The tool's export is read, a person validates what is sensitive	Schedule hours, POS sales
Temporary duplicate	Both tools run while you compare	Temperature readings during a trial period
Replacement over time	The old tool stops on a chosen date	A spreadsheet that has become unmanageable
Out of scope	Tsuno does not touch it	POS, payroll

Deciding, step by step

1. List your current tools and what they really do. Tool: one page, by the owner, with the manager.
2. For each area, choose one of the five options. Scheduling, POS, invoices and supplier price lists, HR and payroll, food safety readings.
3. Name who is authoritative in case of contradiction. One sentence per area: "when in doubt, it is X."
4. Run a first import on one site or one service. Sensitive mappings (who is who, which station, which contract) are validated by a person.
5. Compare after a few weeks. What has been simplified, what is still duplicated, what can be stopped.
6. Retire a tool only on evidence. Not because another promises to do it, but because the duplicate no longer serves a purpose.

Transition mistakes

• Importing everything without deciding who is authoritative.
• Demanding a full replacement in order to judge a tool.
• Leaving a provisional duplicate with no end date.
• Deleting a tool before exporting its data.
• Comparing vendors on sales sheets rather than on your real documents.

Questions to ask your current vendors

Before deciding, ask the vendors you already use: can the data be exported, in what format, and how often? Are the exports complete (history, not only the current month)? Is a connection with other tools planned? Their answers determine what can be imported easily and what will remain manual entry. A good vendor answers these questions without difficulty; it is also your guarantee of being able to leave a tool on the day you decide to.

What to measure

• The number of areas for which the source of truth is decided in writing.
• The number of remaining re-entries of information already present in another tool.
• The number of temporary duplicates with no end date.

Where Tsuno comes in

Tsuno works without changing your whole stack. It is delivered pre-filled (the "La Mise au Carré" service) from your existing documents: extraction, proposed matching, human validation of every sensitive mapping, import, quality control, field review. AI proposes, a person decides. Your data stays yours, exportable. Tsuno covers checklists, training, stations, scheduling, labor cost, food safety readings, incidents and fact-based preparation for employee conversations, but replaces neither the POS nor payroll, and nothing forces you to abandon a tool that works.

Key takeaways

The question is not "what do we replace?" but "what is authoritative, area by area?" Keep what works, import with validation, and retire a tool only on evidence.
