Build Your Own Joyagoo Spreadsheet: Custom Tracker Tutorial

Design Your Columns First

Never start with formulas. Start with questions. What do you need to know about every item? Write your questions down: What is it? Where did I buy it? How much did I pay? What size? What color? Where is it now? Who is buying it? How much profit? Convert each question into a column header. The order matters less than completeness. You can always rearrange later.

Master the Essential Formulas

Currency conversion uses =B2*RATE where RATE is a named cell. Weighted shipping uses =SUM(G2:G50)*GRAM_RATE. Profit margin uses =(J2-F2-H2)/F2 formatted as percentage. For conditional warnings, use =IF(K2<0.2,"LOW MARGIN","OK") to flag items below twenty percent profit. These four formulas power every custom joyagoo spreadsheet template we publish.

Build a Dashboard Tab

Create a second tab named "Dashboard." Pull summary stats from your main sheet using =COUNTIF(Main!L:L,"Delivered") for delivered count, =SUM(Main!K:K) for total profit, and =AVERAGE(Main!K:K) for average margin. Add a sparkline chart tracking profit per haul. Dashboards turn raw rows into decisions. You see instantly whether this month beats last month.

Automation with Google Apps Script

For advanced users, Google Apps Script adds superpowers. Write a script that emails you when an item status changes to "Shipped." Build a webhook that pulls live exchange rates from an API every morning. Create a custom menu button that exports your sold items to a PDF packing list. These automations require zero external apps and run entirely inside your joyagoo spreadsheet.

Custom vs Template Comparison

Testing Before Your First Haul

Add ten fake items to your new sheet. Use round numbers like ¥100 and 500g. Manually verify every total. If your profit column shows $5.00 when you expect $5.00, your formulas are correct. If anything looks wrong, trace the formula by clicking the cell and reading the highlighted references. Fix errors now, not when you have fifty real orders at stake.
