Meaning and transaction use
The International Trade Administration describes a standby as drawable following contractual default, including an importer's failure to pay. Its guide includes standby letters of credit among the techniques used to support open-account trade. The specific instrument determines its operation. [S1]
Proposed review method: map the standby against the actual invoice cycle. Identify which invoices fall within the described obligations, how the amount changes, and whether the presentation window accommodates the payment due date and required documents. Review the issuer and the arrangement for authentication separately.
Worked example
Illustrative sizing example only. Assume unpaid eligible invoices total USD 300,000 and a standby has an available amount of USD 250,000. Assume a planned additional shipment would add USD 80,000 to that exposure before any receipt.
Scroll the table horizontally to view all columns.
| Scenario | Assumed exposure | Gap above standby amount |
|---|---|---|
| Before additional shipment | USD 300,000 | USD 50,000 |
| After additional shipment | USD 380,000 | USD 130,000 |
Under these assumptions, the additional shipment increases the uncovered sizing gap by USD 80,000. Confirm eligibility, reductions, previous drawings and any other protection before using this calculation in a credit approval.

Decision framework
| Situation | Proposed action |
|---|---|
| Seller agrees open-account terms | Check the standby's amount and availability against the expected exposure and invoice dates. |
| New shipments increase exposure | Recalculate the gap before changing the customer's credit limit. |
| An invoice is unpaid | Check the instrument's trigger and document requirements with the appropriate bank or adviser. |
| The commercial relationship continues past expiry | Resolve replacement or extension requirements before relying on continued support. |
Common errors to check
- Treating possession of a copy as proof of authenticity.
- Assuming every invoice is within the instrument's coverage.
- Ignoring expiry while extending payment terms.
- Treating a sizing calculation as confirmation of payment entitlement.
Match the standby to the trading exposure
Bring the authenticated wording, invoice cycle, exposure calculation and expiry dates to a trade-finance review.
