A client had just six weeks to migrate over 205,000 financial and operational records into NetSuite. The stakes were high:
Any delay or data mismatch would have jeopardised month-end close and business continuity.
Defined exactly what would be migrated and locked data to prevent late changes.
Mapped every legacy field to a NetSuite equivalent, or eliminated it if unnecessary.
Used Python scripts to pull data into structured staging databases and clean Excel files.
Weekend load, Monday go-live, and 45-day stabilisation support.
A 180-line Python + Pandas script automated repetitive cleanup tasks such as generating accounting periods from transaction dates, removing Excel errors, and enabling instant corrections.
This eliminated 120+ hours of manual work and cut reconciliation time in half.
import pandas as pd
from datetime import datetime
# Load legacy data (e.g., vendor bills, customers, inventory)
df = pd.read_excel("legacy_data.xlsx")
# 1. Normalize record formats
df['CustomerName'] = df['CustomerName'].str.strip().str.title()
df['ItemCode'] = df['ItemCode'].str.upper()
# 2. Merge duplicates in master data
df = df.drop_duplicates(subset=['CustomerID', 'ItemCode'], keep='first')
# 3. Generate "Period" column from transaction date
df['Period'] = pd.to_datetime(df['TransactionDate']).dt.to_period('M').astype(str)
# 4. Handle missing or incorrect item codes
missing_codes = df[df['ItemCode'].isna()]")
120+ hours
$12,500 saved compared to the original migration scope.
The client spent their first month on NetSuite improving processes, not fixing data issues.
We hired Versich to rebuild our analytics stack after an internal project stalled. They came in, assessed the situation quickly, and delivered production-ready Power BI dashboards within weeks. Their DAX knowledge and data modelling skills are exceptional.
Versich understood our finance workflows from day one. They built dashboards that connected directly to our ERP and gave our leadership team real-time visibility into cash flow, margins, and budget vs actuals. The quality of the work and the speed of delivery were both outstanding
Before Versich, our reporting was scattered across spreadsheets with no single source of truth. They built us a Power BI environment that connects our warehouse, finance, and sales data in one place. Our operations team now makes decisions in hours instead of days
