Source-of-funds narratives that survive a second reading

Source-of-funds sections fail audits less often because of missing stamps and more often because the story and the exhibits disagree. A second reading — the kind an examiner gives — looks for alignment, not decorative completeness.

Match the time window

A statement covering three quiet months does little when the customer claims a lump-sum property sale last quarter. Ask for the period that contains the event named on the application.

Separate salary from side activity

Many Thai retail packs list employment income while free-text notes mention a family trading stall. If your procedure treats secondary income as a trigger, the file should show whether that stall was assessed or consciously accepted.

Watch photocopy generations

Faded transfers and cropped QR slips may still be acceptable under your rules, yet they slow every reviewer. When quality is marginal, a dated note from the officer who accepted the copy prevents later disagreement about whether the exhibit was legible on day one.

Keep the narrative short and checkable

Long essays rarely help. A paragraph that names the source, the approximate amount, and the document type attached is easier to test during a financial audit of know-your-customer applications than three pages of biography.
