The complete LC lifecycle — from issuance through to closure — covered across process flows, functional use cases, and 100 test case scenarios across 8 modules.
A Letter of Credit (LC) is a payment instrument issued by a bank on behalf of an importer, guaranteeing payment to an exporter once specified documentary conditions are met. It is one of the most widely used instruments in international trade finance, governed internationally by UCP 600 (Uniform Customs and Practice for Documentary Credits).
In IT implementation, LC is one of the most complex modules to test — because correctness depends not just on system behaviour but on document compliance rules, SWIFT message formats, and bank-to-bank workflows that span multiple systems and parties.
Banking IT teams implementing or upgrading trade finance platforms — Finastra, Intellect, Temenos, custom builds — need a reliable reference for how LC actually behaves across every scenario, not just the happy path.
The complete set of flows covered in the Bankly LC pack — each one reflected in test scenarios and use cases.
Applicant submits LC application → credit approval → LC issuance → SWIFT MT700 transmission to advising bank → advising confirmation to beneficiary. Covers sight, usance, deferred payment, and acceptance LCs.
Amendment request → beneficiary consent (where required) → issuing bank approval → SWIFT MT707 transmission → amendment register update. Covers amount, expiry date, port, and document changes.
Beneficiary presents documents within validity period → document receipt logging → 5-banking-day examination clock → document checklist verification against LC terms. UCP 600 Art. 14 compliance.
Discrepancy identification → SWIFT MT734 notice of refusal → waiver request to applicant → waiver acceptance / rejection flow → document return or hold instructions. Covers major and minor discrepancies.
Complying presentation confirmation → SWIFT MT750 (query) / MT754 (payment advice) → payment authorisation → nostro settlement → SWIFT MT742 for reimbursement. Covers sight payment and deferred payment maturity.
Auto-expiry on expiry date → unutilised balance reversal → margin release → liability ledger closure → SWIFT MT799 free-format notification where applicable.
First beneficiary transfer request → second beneficiary substitution flows → document substitution at presentation → payment split scenarios between first and second beneficiary.
Partial shipment, tolerance breaches (Art. 30), late presentation, force majeure extension, multiple drawings, revolving LC, red clause LC advance, and cancellation by mutual consent.
LC is one of the highest-risk modules to under-test. These are the areas where system gaps cause real-world failures.
Field-level MT700 validation — mandatory vs optional fields, character limits, codelist values, and multi-bank routing. A single field error causes payment failure.
System enforcement of document terms — invoice amounts, port names, dates, shipper details — exactly as stated in the LC. UCP 600 Art. 14 and ISBP 745 alignment.
LC liability creation on issuance, partial drawings reducing available balance, tolerance calculations (Art. 30 ±5%/10%), and clean closure at expiry or full utilisation.
LC in currency different from account currency — FX rate capture at issuance, revaluation at payment, nostro account reconciliation across currencies.
Tracking amendment sequence numbers, preventing conflicting amendments, handling beneficiary non-acceptance, and reverting terms on rejected amendments.
System logging of discrepancies, applicant waiver request and timeout handling, MT734 generation timing within the 5-day window, and payment trigger on waiver acceptance.
These are the gaps that surface most frequently in LC platform implementations — and what the Bankly pack is built to address.
Teams test that an MT700 generates — but not whether the fields are correctly populated from LC terms, whether the advising bank sequence is correct, or whether the MT707 amendment correctly reflects LC version state.
Many implementations leave document checking to the trade officer rather than building system validation. UAT that doesn't test document rule enforcement misses a significant operational risk.
UCP 600 Art. 30 tolerance and partial shipment rules are complex and frequently misconfigured. Standard test packs rarely cover the boundary conditions — overage, underage, and prohibition interactions.
Issuance creates liability, drawings reduce it, but closure — especially on expired unutilised LCs — often leaves orphaned entries. End-to-end reconciliation from issuance to closure is a consistent UAT gap.
