Eliminate Event Expense Headaches: Mobile-First Google Sheets & GAS Expense Tracker

Common Challenges in Event & Club Accounting

Whether organizing a club camp, sports tournament, company BBQ, or local festival, managing shared expenses is often stressful:

  • Scattered Reimbursements: Member A bought groceries, Member B bought party supplies—who owes whom and how much?
  • Multiple Wallets: Collecting fees via cash and mobile apps (PayPay, Venmo, bank transfers) makes real-time balance tracking confusing.
  • Lost Paper Receipts: Receipts get crumpled, faded, or misplaced before the event wraps up.

Our Mobile-First Event Expense Tracker, built on Google Sheets and Google Apps Script (GAS), solves all these issues instantly.

5 Key Features

  1. Individual Reimbursement Tracking:
    Automatically tracks unpaid balances per member. At settlement time, see exactly what each person is owed (e.g., John: $50 / Sarah: $30). Recording a reimbursement instantly offsets the balance to zero.
  2. Multi-Wallet Balance Management:
    Manage Cash, Mobile Pay, Bank Accounts, and IC cards side-by-side. Real-time formula calculations ensure physical money matches the digital ledger.
  3. Direct Receipt Photo Upload:
    Snap receipt photos on your phone immediately after shopping. Files are automatically uploaded and organized in your dedicated Google Drive folder.
  4. 100% Smartphone-Operable (No PC Required):
    After copying the template, manage everything from mobile. Add, remove, or reorder members and payment methods directly from the Web App settings tab.
  5. Built-in Visual Guide:
    An in-app user guide explains exact workflows for purchases, reimbursements, and inter-wallet transfers.

Typical Use Cases

1. Right After Shopping (Shopper)

Open the web form on mobile → Select Category (“Groceries”), Payment (“Reimbursement”), Name (“John”), Amount ($85) → Attach receipt photo → Submit. Done in 30 seconds!

2. End-of-Day Settlement (Accountant)

Check the Unpaid Balance board → Hand $85 cash to John → Submit Category (“Reimbursement Settlement”), Name (“John”), Paid via (“Cash”). John’s balance clears to $0 and the Cash wallet decreases by $85.

3. Moving Funds Between Wallets (Transfer)

Select Category (“Fund Transfer”), Source (“Cash”), Destination (“Mobile Pay”), Amount ($100). The system automatically creates matching outflow and inflow lines.
