Use Case

ERP Migration & Multi-ERP Operations

ERP migrations and multi-ERP environments expose a fundamental weakness in traditional accounting architectures: the ERP is forced to be both the system of record and the system of detail.

Change ERPs without breaking accounting — or overwhelming them.

Links removes that constraint.

Challenges

The Pain — Before Links

ERP migrations are high-risk because accounting detail, logic, and history are tightly coupled to the ERP itself.

Before: ERP Change as a Financial Reset

  • Ledger locked inside the ERP — accounting logic and history must be rebuilt during migration
  • Transaction overload — operational detail floods the GL, degrading performance
  • Parallel ERP chaos — inconsistent accounting across old and new systems
  • Lost or archived detail — drill-back disappears once systems are retired
  • Audit risk — broken lineage across ERP boundaries
  • Big-bang cutovers — high risk, limited rollback, extended close cycles
Changing ERPs often means starting over — operationally, financially, and audit-wise.

Solution

How Links Solves These Pains

Links decouples financial truth from ERP infrastructure.

Instead of pushing every operational detail into the ERP, Links retains full-detail journals in its own ledger and submits summarized, controlled journals to one or more ERPs.

After: ERP Change Without Accounting Disruption

  • Detailed subledger journals live permanently in Links
  • ERPs receive lightweight, summarized postings
  • Every ERP journal can be drilled back to:
    • Detailed journals in Links
    • The original operational transactions
  • Multiple ERPs can operate in parallel using the same accounting logic
  • ERP migrations become phased, reversible, and low risk
Your ERP becomes a reporting and control endpoint, not the bottleneck.

Why

Why This Matters to Finance

For the Office of the CFO, ERP migration is not a systems upgrade — it’s a continuity event.

Links gives Finance

  • A persistent accounting system of record across ERP changes
  • Clean, explainable journals without flooding the GL
  • Consistent accounting treatment across regions and ERPs
  • Confidence that audit trails survive migrations and acquisitions

For Controllers and Accounting teams

  • No re-implementation of accounting rules
  • No loss of journal detail after cutover
  • No performance degradation from transactional overload
ERP flexibility becomes a strategic advantage, not a risk.

Architecture

How Links Enables ERP Migration & Multi-ERP

Links operates as an ERP-independent subledger and control plane.

Detail Journals Stay in Links

  • All granular journal entries are recorded in Links ledgers
  • Journals retain:
    • Source transaction IDs
    • Operational attributes
    • Full accounting context
  • Prevents flooding ERPs with operational detail

Control Accounts Bridge Subledger and ERP

Links uses control accounts to keep ERPs clean and reconcilable.

ERP journals stay light, fast, and explainable.

Deliver to One or Many ERPs

Links can:

  • Post summarized journals to one ERP
  • Post to multiple ERPs simultaneously
  • Use pre-built “Migrate” button to effectively switch from one ERP to another ERP
Links workflow running the current ERP and the future ERP in parallel during an ERP migration

Impact

Outcome Metrics Finance Teams Care About

Organizations using Links during ERP change consistently achieve:

Zero loss of journal detail

during ERP migrations

70%+ reduction

in ERP journal volume

No increase in close time

during migration periods

Lower audit risk

with continuous drill-back capability

Accelerated integration

Faster post-acquisition integration

Lower ERP migration cost

due to reduced rework

Summary

From ERP Lock-In to Financial Continuity

Before Links, ERP migrations meant rebuilding accounting from scratch.

With Links:

  • Detail stays intact
  • ERPs stay lightweight
  • Accounting logic stays consistent
  • Audit trails stay intact

Modern finance requires ERP flexibility. Links delivers ERP independence.
