The architecture behind THE LAyer
Flexible AI Reconciliation
Donnerstag.ai is the AI Reconciliation Layer that sits between the systems that record financial transactions and the finance teams that depend on those records being true.
We use AI to flexibly adapt to every customer's systems and processes so data ingestion, matching, dashboards and the audit trail become fully customized and automated in 4-6 weeks. Not in months.
your Data and Systems
Automated data source ingestion
All of your data sources ingested into one layer. Structured or unstructured. ERP, PDF, EDI, bank, expense, TMS.
Flexible
Customized matching
Customized deterministic + AI-authored matching rules at line-item level. Confidence score on every match.
Customizable
Real-time dashboards
Every transaction reconciled on the day it posts. Customizable dashboards report in real-time.
Audit ready
Automatic audit trail
Every decision logged immutably. Rule, model, timestamp, user, confidence, rationale.
Reconciliation is inherently customer-specific
Configured to your data and systems.
No two businesses have the same data sources, the same matching rules, or the same exception patterns. We flexibly adapt to every customer-specific case. A solution that fits your ecosystem.
01
Read from your systems of record
ERP, bank, EDI, PDF, TMS, corporate card, T&E feeds. Native connectors, one data model. No middleware, no schema forcing.
02
The engine writes rules against your data
The engine customizes deterministic rules to your specific patterns. Where the patterns are non-obvious, the engine drafts the match rule and your team reviews and approves it. The output is transparent, auditable, yours to extend.
03
Write back, additive and removable
Only team-approved postings into your GL and sub-ledgers the way your auditor expects. Read-from / write-to. Nothing is rip-and-replace, everything is additive.
AI customizes. The matching runs on rails.
Your matching rules. Customized by AI.
AI writes code, not data. The Matching Engine customizes deterministic rules to your specific patterns. When it encounters a non-obvious pattern in your data, it drafts a rule. Your team reviews, adjusts, and approves the rules.
Human-on-the-Loop by design, because auditors read rules, not model outputs.
Customized deterministic rules
Exact, tolerance, and multi-leg matches. Transparent logic your auditor can read and your team can extend. Rules first, always.
AI-drafted rules
Where the pattern in your data is non-obvious, the engine drafts a rule against it. The team reviews, adjusts, and approves it. The rule is the output, not a black-box decision.
Team review on exceptions
Genuine exceptions stay with your team, where judgement belongs. Every override is attributable: rule, user, timestamp, rationale.
The Layer, delivered through Recons
The RECON Library.
Each RECON gets customized so it covers your reconciliation use case end-to-end and strengthens the Layer's coverage without rebuilding anything underneath.

What you get with the AI Reconciliation Layer
01
Reconciliation Confidence
Full reconciliation confidence
Today's reconciliation processes sit below the achievable optimum. The Reconciliation Layer changes that. Automated Data ingestion, normalization, and 100% line-item coverage in real-time stops being a target and becomes the operating condition. Every match carries a confidence score, every exception is raised on the day it appears.

100%
Line-item coverage
Hours, not weeks
Exception backlog cleared
02
Revenue & Margin Recovery
Recover what's lost
At the total, offsetting errors cancel and the loss stays invisible. At line-item, the loss becomes visible on the day it occurs. Dispute windows preserved, not discovered late.
1–3%

Audit-Ready Close
An automated audit trail
Every matching decision logged immutably: rule, model, timestamp, user, confidence, rationale. GoBD, IFRS, SOX stop being a project and become an operating condition.

Real-Time Control
A real-time control plane
AR, AP, bank, intercompany: reconciled throughout the month. When the close begins, everything is already reconciled. Month-end becomes a confirmation, not a catch-up. Treasury plans on reliable data.
