Managing group purchases or bulk orders from platforms like Taobao, 1688, or Weidian can quickly become a complex task. The GTBuy Spreadsheet
Manual calculation for dozens of items and participants is time-consuming and error-prone. Automation with the GTBuy spreadsheet provides: Here’s how to structure your spreadsheet and implement the essential formulas. We'll assume columns for Item Name, Item Price (¥), Quantity, Domestic Shipping (¥), International Freight Weight (kg),Final Cost (¥). Create a column for Item Subtotal. This is the cost of multiple units of the same item. First, calculate the Total Order Valueprice proportion. International freight (sea or air) is usually charged per kilogram (kg). You need the weight of each item. Tip: Keep the Freight Rate (e.g., ¥45/kg) in a separate, clearly marked cell so you can easily update it for all calculations. Combine everything into one final formula for each item line. The Final Cost
In spreadsheet terms, if your columns are B (Price), C (Qty), D (Dom. Ship), E (Weight), and G (Freight Rate cell), a row's final cost might look like: Using Create a summary section that uses An automated GTBuy spreadsheet is more than just a ledger; it's the financial engine of a successful group buy. By implementing these formulas for item subtotals, domestic freight allocation, and international shipping, you create a transparent, accurate, and adaptable system. This not only saves you hours of work but also builds trust within your buying community, ensuring everyone knows exactly what they are paying for.

Building Your Automated Cost Calculator
Step 1: Calculate Item Subtotal
=Item Price * QuantityStep 2: Aggregate Costs and Allocate Domestic Freight
Total Order Value = SUM of all Item Subtotals
Domestic Freight Allocation for an item = (Item Subtotal / Total Order Value) * Total Domestic Freight CostStep 3: Calculate International Freight Allocation
International Freight for an item = Item Weight (kg) * Quantity * Freight Rate (¥/kg)Step 4: The Master Formula for Final Cost
= (Item Subtotal) + (Domestic Freight Allocation) + (International Freight for the item)=(B2*C2) + D2 + (E2*C2*$G$1)$G$1
