Recover what's lost between remittance and invoice

The AR RECONs match every customer payment, deduction, short-pay, chargeback, rebate and statement at the line item on the day it occurs. Dispute windows preserved, not discovered late.

The structural failure

AR breaks at the line item, not at the total

Summary-level reconciliation creates the feeling of control, not control itself. At the total, offsetting errors cancel, the loss stays invisible. Four named failures appear in every enterprise AR stack.

Failure 01

Aggregate blindness

Unauthorised deductions are indistinguishable from authorised at sub-ledger level. The line-item evidence chain never gets assembled.

Failure 02

Expired dispute windows

OTIF, MCB, and chargeback recovery windows close before the document chain reaches the AR analyst's desk. Recovery becomes a write-off.

Failure 03

Cash on account

Unstructured remittance — email, PDF, bank file, portal — hits the sub-ledger aggregated, not at the line item. Cash sits unapplied for days.

Failure 04

No audit trail

Every deduction-vs-write-off decision lives in someone's inbox and a spreadsheet version from six weeks ago. GoBD becomes an end-of-year project.

The 6 AR RecoNS

The AR RECON library

Each RECON covers one of your AR reconciliation use cases end-to-end. Ingestion, matching, exception workbench, audit trail, write-back. Start with one. Build your AR Layer over time.

Ar · RECON 01

Customized to your case

Cash Application RECON

Unstructured remittance advice (email, PDF, bank file, portal) hits the sub-ledger aggregated, not at the line item. Cash sits "on account" for days; AR analysts apply payments manually.

T+0 remittance match

Reduced unapplied cash

DSO improvement

Match Pattern

Customer remittance ↔ Open invoice

· line-item · with partial pay & credit memo handling

Ar · RECON 03

Customized to your case

Deduction Handling RECON

Authorised deductions routed to acceptance; unauthorised deductions routed to dispute workflow with full document chain. The classification — and the evidence — happens on the day of origin, before the dispute window closes.

30% → >80% dispute success

Customer Rebate RECON

Rebate accruals and payouts reconciled ad-hoc. Margin impact invisible until the close. Contract terms and actual customer deductions drift apart.

Auditable payout chain

Rebate accrual ↔ Payout event

Ar · RECON 02

Chargeback RECON

PSP and acquirer chargebacks reconcile across three layers — gateway, bank, sub-ledger — with fees and FX buried in aggregates. Win rates collapse without document-chain assembly. (Absorbs the former PSP & Acquirer Reconciliation page.)

Short-Pay RECON

Partial payments without attribution sit on account; root cause invisible. Without variance reasoning, short-pays accumulate as ageing debt nobody owns.

What AR teams actually get

What AR teams actually get

01

Reconciliation Confidence

AR moves from "as good as scale allows" to "reconciled with confidence."

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.

Revenue Recovery

Recover 1–3% of revenue lost in AR

T+0 detection preserves the dispute window. Recovery rates move from around 30% to over 80% when the document chain is already assembled on the day of origin. Chargeback wins climb from 20–30% to 60–75%.

Audit-Ready Close

Every AR match logged immutably

Every deduction decision, every short-pay attribution, every credit-memo application is logged with rule, timestamp, user, confidence, rationale. GoBD, IFRS, and SOX become a byproduct of running AR.

DSO reflects the actual open-item picture

AR runs throughout the month, line-item by line-item. When the close begins, cash is already applied, deductions classified, disputes in flight. Treasury plans on a real DSO.

Built for your data

Start with one RECON. Build your Layer over time.

Reconciliation is inherently customer-specific. No two AR teams have the same remittance formats, the same reason codes, or the same dispute workflows. Every Flow ships with standardised behaviour and is configured for the cases the standard logic doesn't solve.

Live in 4–6 weeks

Read from · write to

The engine writes rules against your AR data

Where remittance patterns are non-obvious, the engine drafts the match rule against your customers' formats. Your AR controllers review and approve it. The output is a rule — transparent, auditable, yours to extend.

Customer-specific reason codes & tolerance bands

Per customer, per region, per Flow. The deduction taxonomy your Account Managers actually use — not a generic one we force on you.

Human-on-the-Loop on every override

AI accelerates the work; AR controllers own the decision. Every override is logged with rule, user, timestamp, rationale — exportable for the auditor.
