We process about 2,000 international wires a day, and 8% go into a manual repair queue because of field errors, at 6 minutes each. Option A adds front-end validation and should cut the error rate to 3%. Option B is a third-party auto-repair tool at $150K a year that fixes 60% of exceptions automatically. Which would you recommend?

国际电汇每天大约 2,000 笔，其中 8% 因为字段错误要进人工修复，每笔要 6 分钟。方案 A 是在前端加校验，预计能把出错率降到 3%；方案 B 是买一个第三方自动修复工具，年费 15 万美元，能自动修好 60% 的异常单。你推荐哪个？
