GTBuy: Automate Your Group Buy Management

2026-02-21

Managing a group buy involves complex tracking of orders, payments, and deliveries. By adding key formulas to your GTBuy spreadsheet, you can automate calculations, gain instant financial insights, and save hours of manual work.

1. Automating Total Cost Calculations

The foundation of your automated sheet. Combine product cost, taxes, and fees into a single cell.

Core Formula Example:

=IFERROR((ItemPrice * Quantity) + ServiceFee + DomesticShipping + InternationalShipping, "Check Input")

This formula calculates the all-in cost for a member's item and provides an error check.

2. Tracking Refunds & Member Balances

Automatically track who owes money or is due a refund by comparing payments received to final costs.

Balance Formula:

=IFERROR(TotalCost - AmountPaid, "-")

A positive result indicates a balance owed. A negative result indicates a refund due.

Use conditional formatting to highlight outstanding balances in red and refunds in green.

3. Estimating Delivery Timelines

Create a clear, automated schedule for your group. Use simple date logic for projections.

Timeline Formula:

=IF(OrderDate<>"", OrderDate + 14, "") & " - " & IF(OrderDate<>"", OrderDate + 21, "")

This projects a 2-3 week delivery window from the order date, only if an order date exists.
