GTBuy: Generating Monthly Reports with the Spreadsheet

2026-04-10

Leverage formulas and filters to summarize spending, refunds, and delivery efficiency for superior financial oversight.

Effective financial tracking is key to managing any purchasing operation. The GTBuy spreadsheet, when used to its full potential, transforms raw transactional data into a clear, actionable monthly report. This guide walks you through the essential steps.

Step 1: Ensure Clean and Consistent Data Entry

Before any analysis, your data foundation must be solid. Use dedicated columns for:

  • Date:
  • Item/Vendor:
  • Amount:
  • Status:
  • Delivery Date:
  • Order Date:

Step 2: Summarize Total Spending with SUMIFS

To calculate total spending for a specific month, isolate relevant transactions.

=SUMIFS(Amount_Column, Date_Column, ">="&Start_Date, Date_Column, "<="&End_Date, Amount_Column, ">0")

This formula sums only positive amounts (spending) within your defined date range. Create a cell for the month's start and end date to make the report dynamic.

Step 3: Calculate Refund Data

Track reclaimed money separately for accurate net spending.

=SUMIFS(Amount_Column, Date_Column, ">="&Start_Date, Date_Column, "<="&End_Date, Amount_Column, "<0")

Alternatively, use a dedicated "Refund Amount" column and a simple SUMIFNet SpendTotal Spending - Total Refunds.

Step 4: Analyze Delivery Efficiency

Measure operational performance by calculating the average delivery time.

  1. Create a helper column: Delivery TimeDelivery Date - Order Date.
  2. Use AVERAGEIFS=AVERAGEIFS(DeliveryTime_Column, Status_Column, "Delivered", DeliveryDate_Column, ">="&Start_Date, DeliveryDate_Column, "<="&End_Date)
  3. Use the Filter

Step 5: Create a Summary Dashboard

Dedicate a separate sheet or a prominent section as your report dashboard. Link all key metrics:

Metric Formula/Origin
Total Monthly Spend Linked from Step 2 result
Total Monthly Refunds Linked from Step 3 result
Net Spend = [Total Spend] - [Total Refunds]
Avg. Delivery Time (Days) Linked from Step 4 result
Orders Pending =COUNTIFS(Status_Column, "Pending", Date_Column, ">="&Start_Date, Date_Column, "<="&End_Date)
