How to track class attendance and packs without a spreadsheet

Attendance tracking sounds trivial until you are doing it for forty clients across a dozen weekly classes. Miss a log and a client’s pack balance drifts out of sync. Reconstruct the week from memory on Sunday night and you will eventually undercount — and undercounting attendance means giving away sessions you were owed for.

Why spreadsheets break down for attendance

A spreadsheet is a fine place to store data, but a terrible place to enter it in the moment. You are coaching, not sitting at a laptop. So the logging gets deferred to later, and "later" is where accuracy goes to die. The row you forget is the one that costs you.

The problem is not the spreadsheet itself — it is the moment of entry. If you could mark attendance in the two seconds between finishing a class and packing down, the record would always be exact.

Mark attendance from WhatsApp in one message

That is exactly what marking attendance over WhatsApp gives you. During pack-down you send one message — "mark tonight’s attendance" — and Wultor records who was present, decrements each attendee’s pack, and updates your totals. No laptop, no deferred data entry, no Sunday-night reconstruction.

Because pack balances update the instant you log attendance, a client asking "how many classes do I have left?" gets an accurate answer — often without the question ever reaching you.

Packs that stay accurate on their own

The real payoff of exact attendance is exact packs. When every session is logged as it happens, three things follow automatically:

• Remaining classes are always correct, so renewals happen at the right time — not late.
• Clients can check their own balance instead of asking you mid-session.
• You can see a full history of every change, including edits clients made themselves.

Your records, in a sheet you own

None of this means giving up control of your data. Attendance and packs are written to a Google Sheet in your own Drive — the same spreadsheet you already understand. You are just no longer the one typing into it during class. For how the data ownership works, see the FAQ, or browse the rest of the guides.
