Accounts payable / Evidence-led reconciliation

Find the discrepancy. Follow the evidence.

Compare supplier invoices with purchase orders and goods receipts. See which records disagree, which rule triggered, and the source values behind each finding—so your team can review exceptions with evidence instead of chasing spreadsheets.

SAMPLE WORKFLOW · READY TO EXPLORE

Start with a working reconciliation. Open a finding to inspect the source values, matching rule and evidence trail—then decide whether the workflow fits your review process.

LEDGERTRACE / PRODUCT SYSTEMFROM RAW RECORDS TO REVIEWABLE EVIDENCE
How LedgerTrace works Three accounts-payable data sources enter a reconciliation engine. The engine normalizes fields, matches records and applies comparison rules. Results become matched records or traceable exceptions with source evidence for human review.

03 / Who it serves

For finance teams that need to explain a mismatch—not just flag one.

Designed for accounts-payable leads, controllers, bookkeeping firms and finance service providers reviewing supplier invoices against purchase orders and goods receipts. Most relevant where spreadsheet checks recur and reviewers need a defensible trail back to source rows.

A / THE PROBLEM

Checks are scattered.

Invoice, PO and receipt data often sit in separate exports. A status or total alone does not tell a reviewer which row disagrees or why.

B / THE OUTPUT

One reviewable trail.

Compare configured fields, see the triggered rule, inspect source-row references and export exceptions for human review.

C / THE REVIEW

Keep the decision with your team.

LedgerTrace organizes rule-triggered discrepancies and supporting records. Your reviewer determines whether a finding needs correction, explanation or no action.

What you can inspect

Every flagged result has something concrete to review.

  • Compared values from the supplied records.
  • The rule that triggered each finding.
  • Source-row references and related PO/receipt rows.
  • An exportable exception list for human review.
Data handling / Current build

CSV processing stays in this browser tab.

The app reads selected CSV files with browser file APIs and runs its reconciliation logic locally. Its current code does not upload those CSV contents to a LedgerTrace server. Review notes are held in page memory for this session. The site loads web fonts from Google; this is not a claim that the entire browsing session makes no network requests. Use synthetic or approved anonymized records for first evaluation.

A bounded evaluation

Start with one workflow. Validate every finding.

Use approved anonymized CSV exports to test one invoice-to-purchase-order-to-receipt workflow. The evaluation compares tool output with a human-reviewed reference set and documents what was caught, missed, or incorrectly flagged.

  1. Agree the workflow.Choose one AP process, supported CSV columns and the exception types that matter.
  2. Approve the boundaries.Confirm sample size, exclusions, data handling and acceptance criteria in writing.
  3. Run the evaluation.Process up to 500 combined rows after clean inputs and scope approval.
  4. Review the evidence.Receive an exception CSV, findings report and 30-minute handoff within five business days.
A scoped paid evaluation · Terms agreed privately
01Scope

One AP workflow, up to 500 combined CSV rows, and agreed checks.

02Agree terms

Confirm the fee, timeline, deliverables and acceptance criteria with LedgerTrace before work begins.

03Payment

Written scope and acceptance criteria first. Payment through an agreed, legitimate route before work begins.

04Evidence

Exception CSV, findings report, false-positive review and a 30-minute handoff.

The evaluation is scoped with each buyer before work begins. Use synthetic or client-approved anonymized data. LedgerTrace does not claim production-grade security, ERP integration or guaranteed detection. Fees, timeline, deliverables and acceptance criteria are agreed in writing; scope changes require written agreement.

04 / Buyer assurance

Proof before promises.

No inflated savings claims or black-box verdicts. Inspect the sample, define what a correct result looks like, and discuss a bounded paid evaluation with explicit deliverables and limitations.

01 / INSPECT

Try the browser demo first

The included sample runs locally in your browser. Review the inputs, triggered rules and exported exceptions before sharing any business data. No account or upload is required to explore it.

02 / AGREE

Define the expected answer

Before evaluation, agree the sample/reference cases, supported CSV columns, checks in scope and acceptance criteria. Ambiguous records stay reviewable; they are not silently treated as resolved.

03 / MEASURE

Report misses as well as catches

The report should distinguish confirmed findings, false positives and missed exceptions against the agreed reference set. If no suitable reference set exists, we define it with you before making accuracy claims.

Commercial honesty

LedgerTrace is an early, static browser-based pilot—not a certified accounting system. There are no claimed customer results, accuracy rate, savings figure, security certification or production readiness. A paid evaluation covers the agreed assessment, not a guaranteed saving or positive finding. You receive the agreed outputs even if the tool misses cases or produces false positives.

05 / Methodology

A finding should explain itself.

LedgerTrace applies explicit comparisons to the records provided. It does not infer intent, decide whether an invoice is fraudulent, or replace an AP review process.

01 / MATCH

Connect the source rows

Normalize identifiers and compare invoice lines with purchase-order and receipt rows using PO number and item code. Missing or ambiguous relationships must remain visible.

02 / EXPLAIN

Show the rule and values

Flag configured conditions such as duplicate invoice IDs, supplier differences, price deltas, quantity excesses, missing receipts and unmatched source rows.

03 / REVIEW

Keep the human decision

Inspect the evidence, record review notes and export the worklist. A finding is not a payment instruction, and opening it does not resolve it.

06 / Product details

Clear answers before you evaluate.

The important details about matching, inputs, evidence and review are spelled out before you decide whether to use LedgerTrace.

Which records can I compare?

Three CSV exports: supplier invoice lines, purchase-order lines and goods-receipt lines. Each file should include the relevant identifiers, item code and quantity; invoice and PO files should include unit price for price checks.

How are records matched?

The current matching key is purchase-order number plus item code. LedgerTrace then checks configured conditions such as duplicate invoice identifiers, supplier differences, invoice-versus-PO price differences, quantity excesses, receipt gaps and unmatched PO lines. Confirm column mappings and edge cases before using a new data shape.

What can I inspect in a finding?

Select a result to review its invoice row, related PO and receipt rows, compared values, triggered rule and explanation. The workbench supports review notes and CSV export so a person can investigate and record the next step.

Where is uploaded data processed?

In the current version, selected CSV files are processed in your browser; they are not uploaded to a LedgerTrace application server. Use synthetic or approved anonymized data for evaluation, and do not provide confidential records until data handling has been agreed.

What needs separate validation?

Currency conversion, tax and credit-note treatment, split or merged invoice lines, and complex supplier-resolution cases are not covered as general capabilities. A “matched” status means no configured rule triggered; it is not a certification that the invoice is correct or approval to pay.

How do I know the results are useful?

Use a human-reviewed reference set with expected outcomes. Compare findings against that set, record both missed exceptions and false positives, and agree the scope and acceptance criteria before a paid evaluation. Illustrative sample records demonstrate the workflow; they are not customer results.

06 / Paid evaluation

Evaluate it against a known answer.

Five-business-day AP reconciliation evaluation. One invoice-to-PO-to-receipt workflow, up to 500 combined CSV rows, and a fixed fee quoted in writing before kickoff. The five-day clock starts when the agreed files and scope are ready. No payment or accounting action is automated.

You receive: a source-linked exception CSV, a concise findings report, comparison against an agreed human-reviewed reference set, a false-positive and missed-case summary, and a 30-minute review handoff. Acceptance criteria are agreed before work starts: each agreed test case is processed, every reported finding includes its rule and source-row references where available, and the report records known misses and false positives against the reference set.
