Data advisory guide for finance leaders. Assess reconciliation data sources, matching logic feasibility, identifier consistency, and methodology fit—using existing data to improve automation—before tool selection.
Statement reconciliation is one of the most time-consuming tasks in accounting. But before investing in reconciliation tools, the question is whether your existing data—bank statements, supplier statements, ledger records—is available, structured, and consistent enough to support matching and automation.
Most automation initiatives fail because they assume clean data. This guide takes a data advisory perspective: what reconciliation data exists, where it lives, how it can support rule-based or AI-assisted matching—and what governance and quality work must happen first. Learn more about our data-first accounting automation advisory.
This guide covers reconciliation data sources, matching logic readiness, exception data, governance prerequisites, and how independent advisory assesses automation readiness.
Matching statements to ledger data depends on data that is available, formatted consistently, and traceable. Advisory starts by mapping what exists—not by recommending software. See our data-first automation advisory approach.
Here’s what reconciliation data can support when sources and quality are assessed:
These are data foundations—not software features. Our accounting automation advisory evaluates readiness before any tool or vendor is considered. When combined with invoice data readiness, you get a full picture of finance data foundations.
The goal: understand what reconciliation data exists, what supports matching, and what must change first.
Most automation tools assume consistent identifiers, clean formats, and traceable data. In practice, bank formats vary, supplier statements differ, and ledger data may not align. Advisory identifies these gaps before any tool is selected.
Unmapped sources: Bank statements, supplier statements, credit card data—where does each come from? What format? Who owns it?
Identifier inconsistency: Statement transactions and ledger entries use different reference numbers, date formats, or descriptions. Matching fails when identifiers don’t align.
Format variability: Each bank and supplier formats data differently. Extraction and normalisation require format assessment.
Governance gaps: Who owns reconciliation data? Who resolves exceptions? Without clear ownership, automation perpetuates confusion.
Methodology mismatch: Exact matching works when identifiers align. Fuzzy/ML matching adds value when formats vary. Advisory assesses fit based on your data.
Advisory maps data flows and evaluates matching readiness at each stage—before tools or vendors enter the picture.
Where do statements come from?
Advisory questions: Who owns each source? What format? Is data structured enough for extraction? What governance exists?
Statement and ledger data use different formats and descriptions. Advisory assesses:
Matching depends on identifier consistency and data lineage. Advisory evaluates:
Advisory outcome: Matching readiness—what works today, what remediation is needed.
Exceptions—unmatched items, variances, timing differences—need structured data for routing and resolution. Advisory assesses:
Reconciliation compliance requires data that is captured, retained, and traceable. Advisory evaluates:
When statement and ledger data are mapped, governed, and fit for purpose, automation can deliver:
Advisory quantifies current effort (hours, errors, delays) and identifies where data readiness supports automation—and where remediation must come first. See invoice data readiness for the same approach applied to invoice data.
Independent advisory evaluates reconciliation data before any tool or vendor. The focus is on what exists and what must change.
Outcome: Data inventory—sources, formats, ownership.
Outcome: Matching readiness assessment—what supports automation, what remediation is needed.
Outcome: Automation opportunity map—where reconciliation automation can add value, where data work comes first.
Outcome: Clear scope—data remediation vs. technical implementation. Requirements for tool evaluation when readiness is established. Our accounting automation advisory follows this methodology.
Before selecting any tool, advisory evaluates these data dimensions:
Cause: Statement and ledger data use different reference formats, date standards, or descriptions.
Advisory approach: Map identifiers across systems. Assess what normalisation or mapping is needed before matching can succeed.
Cause: Each bank and supplier formats data differently. Extraction and comparison require format assessment.
Advisory approach: Sample formats from each source. Evaluate rule-based vs. AI extraction fit. Identify normalisation requirements.
Cause: Tools assume clean, consistent data. Reality: formats vary, identifiers don’t align.
Advisory approach: Run a data diagnostic first. Map sources, assess matching feasibility, identify gaps before tool evaluation.
If you’re considering reconciliation automation, start with data—not software:
Map reconciliation data sources: Where do statements and ledger data come from? What format? Who owns them?
Assess matching feasibility: Can transactions be linked reliably? What identifiers exist? Are they consistent?
Identify methodology fit: Exact vs. fuzzy/ML—what fits your data? Advisory provides independent assessment.
Define requirements before tools: Outcome-focused requirements ground tool evaluation in your data reality.
