Project overview
A guided migration platform that connects to QuickBooks, maps and validates accounting data, and moves it in controlled, fully tracked runs.
Accounting data carries years of history — customers, vendors, accounts, invoices and transactions that must arrive in the new system complete and correct.
KMK Ventures needed a dependable way to migrate that data into QuickBooks Online. We engineered a guided platform that turns a risky, manual process into a repeatable workflow with validation and visibility at every step.

The challenge
The Challenge.
Fragile manual exports
Data was exported to spreadsheets, reshaped by hand and re-imported — slow and easy to get wrong.
Mismatched structures
Charts of accounts, custom fields and entity types rarely line up between source and destination.
No validation before import
Problems surfaced only after data landed in the destination, when they were hardest to fix.
Zero visibility mid-migration
Teams couldn't see progress, failures or what still needed attention.
The approach
How We Engineered It.
- 01
Map the data landscape
Catalogued entities, fields and relationships across QuickBooks editions.
- 02
Design a guided flow
Connect, select, map, validate, migrate — one clear step at a time.
- 03
Validate before moving
Every record checked against destination rules before a single write.
- 04
Make runs observable
Progress, logs and errors visible in real time and after the fact.
- 05
Harden the edge cases
Retries, partial failures and re-runs handled deliberately.
The solution
The Solution.
A migration platform with QuickBooks connectivity, custom mapping, pre-migration validation, controlled migration runs, error handling and live progress tracking.
Chart of accounts
162 matched2 to reviewWhat we built
A step-by-step migration platform built on the Intuit QuickBooks APIs — from secure connection to a fully logged migration.
QuickBooks connectivity
Secure OAuth connections to QuickBooks Online and supported desktop sources.
Data migration
Controlled migration of customers, vendors, accounts and transactions.
Import / export
Structured extraction from sources and import into the destination.
Mapping
Custom field and chart-of-accounts mapping between source and destination.
Validation
Pre-migration checks with clear, actionable validation reports.
Migration workflow
A guided wizard that keeps every run consistent and repeatable.
Error handling
Failed records isolated, explained and ready to retry.
Progress tracking
Live progress per entity with detailed migration logs.
Architecture
How It Fits Together.
- 1Source connectors isolate each QuickBooks edition behind a common interface.
- 2Mapping and validation run before any write, so the destination only receives clean data.
- 3Every run is logged per record, making failures traceable and retries safe.

Business value
What It Changed.
Validated, complete data
Issues caught before import, not discovered in the books.
Less manual effort
No spreadsheet reshaping or re-keying.
Full visibility
Progress, errors and logs for every run.
A repeatable process
The same reliable workflow for every migration.
Key learnings
What We'd Tell The Next Team.
- 01
Validation is the product
In accounting migrations, catching problems before import matters more than raw speed.
- 02
Mapping needs a human in the loop
Automation proposes; people confirm. The UI is designed for that partnership.
- 03
Observability builds trust
Showing exactly what happened is what makes teams comfortable running migrations.
