ACBUY: Streamlining Operations – How to Merge Data From Multiple Vendor Accounts

2026-03-27

For large-scale advertisers and agencies managing countless campaigns across platforms, fragmented data is the ultimate efficiency killer. ACBUY presents a systematic approach to consolidating your scattered vendor logs into one master spreadsheet, unlocking clarity and control.

The Challenge: Data Silos in Multi-Vendor Operations

When you run campaigns on multiple platforms—be it Google Ads, Meta, TikTok, or a dozen programmatic vendors—each provides reports in different formats, metrics, and schedules. This leads to:

  • Time-Consuming Manual Work:
  • Increased Error Risk:
  • Poor Visibility:
  • Reporting Inefficiency:

The Solution: Building a Unified Master Spreadsheet

Consolidation is not merely combining files; it's creating a structured, reliable single source of truth. Follow this actionable framework.

Phase 1: Planning & Structure

  1. Define Key Metrics:
  2. Design Your Master Template:Date, Vendor, Campaign_ID, Campaign_Name, Spend, Impressions, Clicks, Conversions, etc.
  3. Establish a Schedule:

Phase 2: Data Collection & Normalization

  1. Automate Exports Where Possible:
  2. Normalize the Data:
  3. Convert currency to a single standard.
  4. Align date formats (YYYY-MM-DD is recommended).
  5. Map vendor-specific metric names to your master column names (e.g., "Cost" → "Spend").

Phase 3: Merging & Automation

  1. Manual Merge (Initial/Ad-hoc):QUERY, IMPORTRANGEPower Query
  2. Advanced Automation (Scalable Solution):
    • Use a script (Google Apps Script or Python) to automatically normalize and append new data to your master sheet.
    • Invest in a dedicated data integration platform (like Supermetrics, Fivetran) to handle the entire process automatically.
  3. Append, Don't Overwrite:
