A 12-point self-diagnosis checklist for operators who run their customer ledger in Excel and their shifts in a LINE group. From taking stock of your current workload to deciding when to migrate to an industry-specific SaaS.

Running your customer ledger in Excel and your shifts in a LINE group is perfectly rational when you start out. But as cast and customer counts grow, the setup breaks down somewhere.

This article gives you a 12-point checklist to judge whether your venue has reached the limit of Excel/LINE operations.

The Checklist (12 Items)

Count how many of the following apply to you:

🔴 Workload

□ 1. The manager loses 2+ hours every weekend to shift collection Work schedules arrive from each cast member over LINE, and someone manually consolidates them into Excel.

□ 2. Month-end payroll takes 2-3 days Hours worked × nomination counts × options, computed by hand — bouncing between a calculator and Excel.

□ 3. You find yourself asking "what happened last time?" while taking reservations Every time the phone rings, someone searches Excel; pulling up a guest's info takes 30+ seconds.

🔴 Incident risk

□ 4. NG (do-not-assign) incidents happen at least once a month A verbal handoff slips, an NG cast member/therapist gets assigned to the wrong guest, and it turns into a complaint.

□ 5. Double-booked reservations happen at least once a week Bookings live on a whiteboard or in LINE, so two guests end up assigned to the same therapist, table, or time slot.

□ 6. You have lost — or worried about leaking — customer contact details A misplaced USB stick or phone with the Excel file on it makes you uneasy about how the guest list is managed.

🟡 Opportunity loss

□ 7. You cannot trace which advertising channel a guest came from You spend meaningful ad budget every month, but no numbers tell you which channel actually performs.

□ 8. You cannot answer when asked about your repeat rate New vs. repeat ratios and second-visit rates are known only by gut feel.

□ 9. Cast evaluations are gut-based, and one-on-ones end in pep talks Without numbers like repeat nomination rate and churn rate, coaching direction stays vague.

🟡 Growth blockers

□ 10. Training new staff means copying "what's in the manager's head" There is no manual, and operations wobble whenever the manager is away.

□ 11. Opening a second venue stalls on information sharing There is no mechanism for cross-venue customer data or consolidated analysis.

□ 12. Cast tell you "other venues let you submit shifts from your phone" The gap versus other venues is starting to affect staff retention.

Your Result

0-2 items: Healthy Your current operations are fine. Re-run the checklist as you grow.

3-6 items: Caution Some limit signs are showing. Process improvements may still help — try operational fixes first (write manuals, restructure the Excel files) before deciding.

7-9 items: Migration evaluation recommended You are approaching the limit of Excel/LINE operations. This is the phase to evaluate an industry-specific SaaS. Left alone, the manager's mental load can reach a breaking point.

10+ items: Migrate now Opportunity loss and incident risk are high, and the longer you wait, the more it compounds. Trying a 30-day free trial first and deciding afterward is a low-risk way to move.

Which Items an Industry-Specific SaaS Solves

Of the 12 items above, tasteck structurally addresses 11 (item 6, data loss, also depends on the user's own security practices, so it is excluded).

Item	How tasteck addresses it
Shift collection	Cast submit directly from their phones
Payroll	Automatic hours tallying + CSV export
"What happened last time?"	CTI caller-ID pop shows guest info instantly
NG incidents	Automatic NG warnings
Double-bookings	Drag-and-drop timeline + automatic conflict warnings
Ad effectiveness	Per-channel acquisition cost / LTV analysis
Repeat rate	Auto-computed via customer rank analysis
Cast evaluation	Repeat nomination rate × churn rate, 2-axis view
Training	AI support + automatically updated manuals
Multi-venue	Corporate group features + cross-venue analysis
Phone-based shifts	Cast mobile app

Why spreadsheets hold on for so long

Nobody chose a spreadsheet. It accumulated, one column at a time, and every column was the right decision on the day it was added.

It fits exactly

⇒ A spreadsheet matches your venue precisely, because you built it around how you actually work. No purchased system will fit that well on day one, and that gap is the real reason migrations get postponed.

One person understands it

⚠️ Usually the person who built it. That is convenience while they are there and a single point of failure the moment they are not.

It costs nothing visible

The cost is entirely in hours, and hours spent typing do not appear on any invoice.

⇒ The Two Places You Type The Same Thing

What the move actually costs

Money is rarely the obstacle. Four other things are.

The hours to move the data

Records to move × minutes per record that cannot be automated

⚠️ The uncleanable portion is what decides the total, and it depends entirely on how consistent your existing records are. ⭕ Pull one hundred rows and count how many need a human. That sample settles the estimate in twenty minutes.

The weeks of running both

⇒ Running old and new together is the only safe way to move, and it means doing some things twice for a period. Budget for it rather than discovering it.

The slowdown while people learn

Every task takes longer for a while. ⚠️ Changing over in your busiest month guarantees the slowdown lands when you can least absorb it.

The things you will find

⭕ Migrations surface duplicate records, prices that disagree, and shifts that were never recorded. That is a benefit, but it is also work that appears without warning.

⇒ The Price List That Lives In Three Places

What to move and what to leave

Moving everything is the most common mistake and the most expensive one.

Move what you will act on

Current guests ／ live bookings ／ active staff ／ current prices

Leave what you only need to look up

⇒ Historical records that nobody edits can stay where they are, exported and stored. They do not need to be in the new system to be available.

Decide the cut-off before you start

⚠️ Without a date, the scope grows during the move, and the move stops having an end.

The order that works

One: the thing that hurts most

⭕ Start with whichever checklist item you scored worst on. A migration that fixes the daily pain first buys the patience for the rest.

Two: the thing that feeds everything else

⇒ Usually the guest record. Most other functions read from it, so moving it early makes the later steps simpler.

Three: everything that can wait

⚠️ Reporting last. It is the most visible and the least urgent, and doing it first produces a system that looks finished and does nothing.

⇒ The Report You Open Every Monday

What breaks during a move

The record that exists in both

Somebody updates the spreadsheet, somebody else updates the new system, and now there are two versions. ⭕ One place is the truth at any moment, and everyone needs to know which.

The person who kept it in their head

⇒ The Shift Swap That Never Got Recorded

The field that has no home

Every venue has one column that does not map to anything. ⚠️ Decide where it goes before the move, not during it.

What stays hard afterwards

Being honest about this makes the decision easier, not harder.

Somebody still has to type

⇒ A system removes duplicate entry. It does not remove entry. If the note at the end of the table is not being written now, it will not be written afterwards either.

The numbers only work if the input does

⚠️ A report built on incomplete records is wrong faster and more confidently than a spreadsheet is.

⇒ The Question You Cannot Answer

Habits outlast tools

⭕ The month-end that took two weeks takes two weeks in any system until the underlying practice changes.

⇒ The Month-End That Takes Two Weeks

How to decide when you scored in the middle

Three to six items is genuinely ambiguous

⇒ At that score the spreadsheet is still working and the cost of moving is real. Neither answer is wrong.

The question that resolves it

Is the number going up or down?

⚠️ A venue at four items and growing will be at eight in six months. A venue at four and stable can wait. The direction decides it, not the level.

And one practical test

⭕ Ask how long it would take to answer: which guests came twice last month and not at all this month. If nobody can, the spreadsheet has stopped being a record and become a filing cabinet.
