How reconciliation works

How reconciliation works

Records from different sources flow through Donnerstag.ai reconciliation layer.
Relevant fields are identified automatically and evaluated at position level. Matched records are classified by confidence, while deviations are clearly highlighted. Discrepancies are captured as structured system outcomes, ready for review and resolution. All reconciliation results remain consistent and traceable across related records and reconciliations.

Explainable proof for every discrepancy

Explainable proof for every discrepancy

Donnerstag compares expected records against actual records at position level using clear, deterministic logic supported by AI. When values do not align, the deviation is isolated and documented with an explicit reason.
Each discrepancy is mathematically traceable back to its source, making differences transparent, explainable, and auditable.

Every record, rule, and reconciliation outcome is fully traceable back to its source. Original data remains unchanged, while all logic, decisions, and actions are documented according to defined rules. Findings can be automatically reported and reviewed, creating audit-ready results without manual effort.

Reconciliation across complex operating environments

Reconciliation across complex operating environments

Industry-specific reconciliation challenges require more than generic matching.

Industry-specific reconciliation challenges require more than generic matching.

Logistics

Logistics

Delivered services vs. contracted transport rates, including surcharges and accessorials

Why this is a problem

Services are delivered in fragments, while rates and surcharges change frequently. Invoices often bundle multiple services, making manual validation slow and error-prone. Small deviations accumulate over time and are difficult to prove.

B2B Services

B2B Services

Logged service hours vs. contract scope and recurring self billed/invoices

Why this is a problem

Service delivery is recorded operationally, while billing follows contractual assumptions. Deviations in hours, scope, or timing are common and hard to track across billing periods, leading to disputes or unnoticed revenue leakage.

Retail

Retail

Delivered quantities and returns vs. selfbilled/invoices and customer deductions

Why this is a problem

High transaction volumes and frequent returns create mismatches between delivery data, invoices, and payments. Deductions are often applied without clear references, forcing teams into manual exception handling.
