Excel Master Supplier Sync

Job ID: 40476854

Budget: $10 – $50 AUD

I keep several supplier-specific workbooks in a single folder and want a single “source of truth” file that every one of them can pull from. The master workbook needs to hold each supplier’s company name and full contact information, and whenever a detail is edited in any file, that change should flow automatically—no buttons to press, no schedules to wait for.

Here is how I picture it working: the master file sits in the folder and, through VBA, Power Query or another robust method, watches for changes in the satellite workbooks. When a conflict occurs, the newest entry wins so the master always shows the latest data. All linked files should then refresh instantly so users see the same, up-to-date details in every sheet they open.

Deliverables
• Master workbook pre-populated with sample fields for Company Name and Contact Information
• Code or queries that create the two-way, real-time link with all other workbooks in the folder
• Clear setup notes so I can drop new supplier files into the folder and have them connect automatically

Please build with reliability in mind; I’d like to hand this to non-technical staff and trust it will simply work.
