[EN] Stop Manual Reconciliation: How I Built a Self-Managing Registration Flow

A QE engineer’s breakdown of automated registration, payment tracking, and list management. Let systems handle order, humans handle warmth.

If you read my Chinese post on the”volunteer breakdown story,” this piece explains why the collapse happens and how system design prevents it.

If you ask me what the most painful moment for an event organizer is, I'd say: it's the night before the event, staring at bank transfer records and an Excel sheet, realizing the numbers don't match.

That anxiety is physiological. Your heart races, your palms sweat, because you know dozens of eyes will be on you tomorrow, and you still don’t know who actually paid.

In my previous article, I shared the EventFlow Starter free template. Today, I want to break down the engineering logic behind it.

This isn’t about “How to use Google Sheets.” It’s about How to think through chaos.

Problem Breakdown: Chaos Comes from Information Fragmentation：

The biggest flaw in traditional event workflows is fragmented data:

• Registration lives in Google Forms

• Payments live in bank accounts

• Communication lives in LINE/Email

• The final list lives in the organizer’s head or a fragile Excel file

These four silos have no bridge. The organizer becomes a “human bridge,” constantly moving, comparing, and translating data. That’s where errors and burnout begin.

Core Design Principle:

Single Source of Truth（SSOT）

💡 In simple terms: Data should exist in only one place. Everything else pulls from it. No more version chaos.

In engineering, we enforce SSOT. EventFlow’s philosophy is straightforward: All information must flow into one place and update automatically.

Step 1: Structured Input

No open-ended notes. Attendees must select clear options (dietary preferences, invoice needs, etc.). This ensures clean, processable data from day one.

Step 2: Status Tagging Over Real-Time Reconciliation

In the Starter version, reconciliation is simplified. Organizers just check “Paid” in the sheet based on bank records.

🔑 Key design: The sheet auto-calculates “Paid Count” and “Remaining Slots.” You don’t need to do mental math. The system tells you exactly what’s left.

Step 3: Dynamic List Output

Organizers always see a live-updated list. Export it to PDF or Excel anytime. That file becomes the single truth. Volunteers use it for check-in. No disputes.

From “Chasing Tasks” to “Tasks Finding You”

Traditionally, organizers actively hunt for “Who hasn’t paid?” or “Who has special requests?” With EventFlow, conditional formatting and filters do the work:

🔴 Red: Registered >3 days, unpaid → Trigger reminder 🟢 Green: Paid & complete → Trigger confirmation

This isn’t just time-saving. It’s a shift in cognitive load. You no longer memorize details. You only handle system-flagged exceptions.

It’s Not a Cold Tool. It’s Your Digital Assistant

Some worry automation kills human warmth. My experience says the opposite.

When I save 3 hours on reconciliation, I gain 3 hours to:

• Reply to attendee questions with care

• Check on volunteer well-being

• Optimize the actual event experience

✨ Systems handle order. Humans handle warmth.
