Ask most contractors what worries them about an ERP migration and you’ll hear about the platform: which one, how long it takes, what it costs, how disruptive go-live will be. Almost nobody starts by asking a more basic question: is the data we’re about to move actually trustworthy in the first place.
That’s the question data integrity is really about, and it’s a different question than “will the migration work.” A migration can execute flawlessly, move every balance and every transaction exactly as instructed, and still hand a company a new system built on top of the same misalignments, gaps, and inconsistencies that had been quietly accumulating in the old one for years. The new platform doesn’t fix that. It just gives it a new home.
What data integrity actually means in an ERP context
Data integrity isn’t a vague quality signal. In practice, it comes down to a specific, answerable question: do your subledgers actually align with your general ledger.
Over years of running a system like Sage 300 CRE, that alignment tends to drift. A journal entry gets posted directly to the GL to fix something quickly, bypassing the subledger it should have flowed through. A job cost adjustment gets made in one module but not reflected in another. A workaround gets built to handle a reporting gap, and it quietly becomes a permanent fixture nobody remembers isn’t part of the original design. None of these individually breaks anything. Together, over enough years, they add up to a system where the numbers technically balance but the underlying detail supporting them doesn’t fully hold together.
This is invisible in day-to-day operations, because day-to-day operations mostly touch summary numbers, not the full transactional trail underneath them. It becomes very visible the moment someone needs that trail: an auditor testing job cost support, a surety underwriting a bond renewal, a migration that requires the historical detail to actually be there and actually be accurate.
What this looks like in practice
None of this shows up as a dramatic failure. It shows up as small, easy-to-rationalize gaps that accumulate quietly over years.
A cost code gets renamed or restructured at some point, and older job cost entries never get remapped to match, so historical reporting on that job silently splits across two naming conventions. A payroll adjustment gets entered as a manual journal entry during a busy close instead of through the proper subledger, because it was faster, and it works fine until someone later tries to reconcile payroll subledger detail against the GL and finds a gap they can’t explain. A subcontractor retainage balance gets tracked in a spreadsheet outside the system because the software’s native handling never quite fit the company’s actual retainage terms, and that spreadsheet becomes the real source of truth for a number the ERP thinks it already owns.
Individually, each of these is a reasonable shortcut taken under real time pressure. Collectively, over a decade of operation, they’re the reason a system’s ending balances can be technically correct while the transactional history supporting them has quietly come apart at the seams.
Why this is a bigger risk than the platform decision
It’s worth being direct about this: choosing between Sage Intacct and Acumatica, or any other destination platform, is a real decision with real tradeoffs. But it’s not the decision most likely to hurt a company after a migration. Data integrity problems are.
A platform that isn’t a perfect fit is usually a manageable inconvenience. A migration that carried forward misaligned subledgers, incomplete job cost history, or GL balances that don’t actually reconcile to the detail behind them is a different kind of problem, one that surfaces later, often at the worst possible moment, and is far more expensive to untangle after the fact than it would have been to catch beforehand.
That’s the case for treating data integrity as its own diagnostic step, separate from and prior to the migration itself.
How TransformerIQ approaches this
TransformerIQ’s ERP Data Integrity Assessment exists specifically to answer the subledger-to-GL alignment question before anything moves. It provides a comprehensive analysis of a system’s health: where subledgers and the general ledger are actually aligned, and where risks, inconsistencies, or structural issues exist that could compromise a migration or cause problems downstream if they went unaddressed.
That diagnostic work feeds directly into how the migration itself is built. TransformerIQ’s approach preserves full transactional history across the areas that matter most for a construction business. Accounts Receivable and Accounts Payable move with complete invoice-level detail and full supporting documentation, not just closing balances. Job Cost carries forward existing work-in-progress along with the transactions that built it, not a snapshot. The General Ledger moves with full account balances and transaction history intact. All of it stays reconciled against each other throughout the process, rather than arriving in the new system as four sets of numbers that happen to tie out on day one without anyone having verified the path that got them there.
Two additional pieces extend this into ongoing operations rather than treating data integrity as a one-time migration event. WIP Replication keeps project reconciliations current in real time, so work-in-progress isn’t a static balance that only gets revisited at period-end. The Readiness & Analytics module provides pre-migration insights and system health checks up front, along with a post-migration analytics foundation, so data integrity remains something a company can actually verify and monitor going forward, not just something that was true on go-live day and unknown after.
Taken together, the point of this approach isn’t just that more data survives the migration. It’s that the data arriving in the new system has actually been checked, reconciled, and verified before anyone builds a new set of reports, dashboards, or audit workpapers on top of it. A migration that moves a lot of history without verifying its integrity first just relocates the same unresolved risk to a new address.
Why this matters even if you’re not migrating this year
None of this requires an active migration decision to be worth acting on. A data integrity assessment is useful information about the health of a system a company is actively running today, independent of whether or when that company moves to a new platform.
Companies that have run Sage 300 CRE for a decade or more, patched around gaps as they came up, and never had a reason to formally verify subledger-to-GL alignment are, more often than not, carrying more risk in their current data than they realize. Finding that out now, on a company’s own timeline, is a very different experience than finding it out during an audit, a bonding renewal, or a migration that’s already underway.
Where to start
TransformerIQ’s Pre-Flight Analytics assessment is built around this same diagnostic foundation, giving a free, no-commitment read on a company’s data quality, complexity, and migration readiness. It’s a useful first step whether a migration is planned for this year or not yet on the calendar at all.
