The Go-Live Date That Keeps Moving
You've signed the contract. Yardi Voyager, MRI, or Procore is deployed. Your implementation partner has configured the modules. UAT is scheduled for Q3. Then someone on your data migration team sends an email that makes your stomach drop: "We need to talk about the lease abstractions."
This scenario plays out across the industry with alarming regularity. According to internal benchmarks from major consulting firms, roughly 30% of real estate ERP implementations experience significant delays, not because the software failed, but because the data wasn't ready to meet it.
The culprit isn't your systems integrator. It isn't the platform. It's the decade of legacy data sitting in spreadsheets, PDFs, and disconnected property management systems that nobody wanted to audit until go-live was eight weeks away.
The "Garbage In, Disaster Out" Reality of ERP Upgrades
Modern ERPs are sophisticated machines. They calculate NOI with precision. They automate CAM reconciliations. They generate investor-ready reports in seconds. But they have one non-negotiable requirement: structured, validated data.
What most organizations discover—usually too late—is that their legacy data is unstructured chaos. Lease abstractions have inconsistent date formats. Vendor master files contain thousands of duplicates ("ABC Plumbing," "ABC Plumbing LLC," "ABC Plumbing Inc." all representing the same contractor). Tenant records are populated differently across properties because three regional teams used different conventions.
The ERP doesn't care about your historical reasons for this inconsistency. It requires uniformity. And when you attempt to load 15,000 lease records with mismatched schemas into a system expecting clean relational data, the result isn't a minor inconvenience: it's a complete stop.
Why Your Internal Team Shouldn't Be Doing Data Entry
When the data gap becomes apparent, the instinctive response is to assign it internally. After all, your property accountants know the portfolio. Your lease administrators understand the nuances. Why not have them clean the records?
The answer is opportunity cost. Your senior lease administrator, earning $95,000 annually, shouldn't be spending three months standardizing tenant contact fields. Your property accountants shouldn't be reconciling duplicate vendor records when they should be closing the month-end. Every hour your experienced staff spends on data hygiene is an hour they're not spending on the analytical work that justifies their compensation.
Then there's the morale dimension, which the industry quietly calls "implementation fatigue." When a team that signed up to learn a new platform realizes it must first manually remediate 5,000 lease records, engagement collapses. The project, intended to modernize their workflow, has instead become a data-entry assignment. Key contributors are starting to update their LinkedIn profiles. Institutional knowledge walks out the door precisely when you need it most.
The math is straightforward: specialized labour for specialized tasks. Your internal team's value is domain expertise and business continuity. Data normalization is a volume-intensive work that scales better with dedicated resources.
Software Configuration vs. Data Readiness: The Distinction That Matters
Implementation partners excel at software configuration. They understand how to map your chart of accounts, configure your approval workflows, and optimize your reporting hierarchies. This is skilled, valuable work.
But software configuration assumes the underlying data is ready. It's the equivalent of hiring an architect to design a building without first surveying the land. The design might be flawless, but if the foundation can't support it, the project fails.
Organizations that execute ERP implementations on schedule typically recognize this distinction early. They engage specialized data partner firms that focus exclusively on BPO-style data cleanup, lease abstraction normalization, and record deduplication before the implementation partner begins configuration. They deploy automated middleware solutions to address ongoing integration challenges between legacy systems and modern platforms, rather than relying on manual data transfer processes that introduce errors at scale.
This isn't about adding vendors to your project. It's about matching capabilities to requirements. Configuration expertise and data remediation expertise are different disciplines. Expecting one partner to excel at both is how timelines slip.
The Audit That Should Happen Before the Contract
If you're six months from an ERP implementation, or considering one, the most valuable exercise you can conduct isn't a software demo. It's a data audit.
Pull a representative sample of lease abstractions. Count the inconsistencies. Query your vendor master for duplicates. Ask your property accountants how many manual adjustments they make each month because "the system doesn't have the right data." The answers will tell you more about your implementation timeline than any project plan.
30% of stalled implementations share a common thread: they treated data readiness as a phase to address during implementation rather than as a prerequisite for starting it. Successful implementations treat data remediation and system integration as parallel workstreams that must be resourced independently.
Your software vendor will deliver on their promises. Your implementation partner will configure your purchase. The question is whether your data will be ready to meet them.
That's not their problem to solve. It's yours. And the time to solve it is before the contract is signed, not after the go-live date has slipped for the third time.
