逾期付款的委婉提醒技巧 — 国际贸易填空题

出口商就 Invoice No.4093 的逾期货款拟发首封催款函。为体现逾期付款的委婉提醒技巧，函中应假定买方属无意疏忽、不直接指责其失信，并委婉请求尽快付款。函中空缺处最恰当的补全是：Dear Sirs, We should like to ______ your attention to the outstanding payment for Invoice No.4093, which we trust has escaped your notice, and would appreciate your early settlement.（请填入一个英文动词）
