IWG Reconciliation | Executive Summary

Two reconciliation domains, one operating model: controlled matching, auditable posting, and exception-led operations.

The source documents describe the current business rules and technical implementation for Card Reconciliation and Interbank Reconciliation, with a common future-state theme: preserve proven matching behaviour while moving to configurable, provider/bank-neutral Dynamics 365 patterns.

Source set: 4 documentsCoverage: Card + InterbankAudience: Executive / Finance / TransformationFocus: Business outcomes, controls, Dynamics implications
1

End-to-end traceability

Every automated match and posting should retain a link back to source bank, PSP, acquirer, invoice, merchant, or settlement data.

2

Configurable rules

Provider, country, bank, currency, COBO/POBO and GL routing variations should be configured rather than hard-coded.

3

Balanced journals

Settlement, commission, exchange, bank, AR/AP, GL and intercompany postings must balance before ERP export.

4

Exception discipline

Unknown setup, ambiguous references, currency mismatches, duplicate candidates and unbalanced batches are held for review.

Card Reconciliation

Customer card payment to settlement lifecycle

Card reconciliation is a two-sided process: first match the PSP/customer-facing payment to the invoice, then match the acquirer settlement back to that already matched payment.

  • Normal purchases and refunds require exact reference, transaction type, sign, amount and entity validation.
  • Gross, commission, net settlement and exchange differences are calculated separately for clear audit and accounting treatment.
  • COBO card settlements require net transfer from billing/source entity to the collecting entity through balanced intercompany journals.
Interbank Reconciliation

Daily bank statement to ERP posting lifecycle

Interbank reconciliation imports bank statements, classifies each line, applies ordered auto-matching rules, posts matched lines, and routes unresolved items to manual review.

  • Supports MT940/SWIFT, NACHA, proprietary CSV, FTP/SFTP/TIS and manual statement upload routes.
  • Matches AR, AP, intercompany, Direct Debit, ROR, ZBA, Boleto, Lockbox/eBill and GL transactions using configurable priorities.
  • Uses initial and final posting concepts so bank activity is accounted for even while final allocation is still pending.

Operating process in one view

Common control pattern
1
Import

Receive PSP/acquirer files or bank statements through provider, bank, TIS, FTP/SFTP, SWIFT, NACHA or manual upload.

2
Validate & classify

Confirm active setup for provider, bank, merchant, terminal, card type, currency, entity and transaction category.

3
Match

Apply priority rules: invoice/reference first, then amount/name, learning, balance, due/combinations or specialist country rules.

4
Post

Create balanced ERP journals for AR/AP, bank, clearing, commission, exchange, GL, intercompany, COBO/POBO and ZBA flows.

5
Monitor

Track matched, unmatched, posted, skipped, errored and unbalanced items with clear reason codes and reprocessing controls.

Major business rules to preserve

AreaExecutive takeaway
Matching sequenceUse deterministic, ordered rules. Do not let fallback rules override stronger invoice/reference matches.
Exact amount controlNormal invoice, card, refund and bank matches depend on exact amount/sign unless a documented tolerance, FX or country rule applies.
COBO/POBO/ZBACentral collection/payment structures must identify the true billing or originating entity and post the appropriate intercompany or franchise/customer/supplier treatment.
Provider/bank variationsWorldpay, GlobalCollect, Stripe/POP, AMEX, Wells Fargo, Brazil Boleto, Colombia NIT, Mexico FX and France/Germany DD differences must remain explicitly configurable.

Technology implications for Dynamics 365

CapabilityNeeded design response
Configuration-first engineParsing, matching priority, GL routing, currencies, providers, banks and country exceptions need business-owned setup, not custom code branches.
Audit data modelStore source-file IDs, source lines, match rule IDs, transaction keys, posting keys and manual override history.
Exception workspaceFinance users need search, manual match, write-off, GL post, bucket movement and controlled skip capabilities.
Safe reprocessingRe-runs must be idempotent: no duplicate journals, duplicate exchange differences, duplicate matched detail rows or repeated COBO transfers.
Strength

Strong control framework

The documents define clear gates: setup validation, exact matching, source traceability, balanced postings and manual review for exceptions.

Risk

High configuration complexity

The future model must absorb many country, provider, bank format and account-routing variations without creating brittle customisations.

Decision

Migration priority

Prioritise a canonical reconciliation model, then map card, bank, DD, COBO/POBO/ZBA and country rules into reusable configuration layers.

Executive conclusion

The reconciliation landscape is mature but complex. The safest Dynamics 365 path is not to replicate every legacy procedure line-for-line, but to preserve the business behaviours: ordered matching, entity correctness, separate economic components, balanced accounting, clear exception handling and full auditability from source file to ERP journal.
