合并发票文件。PDF 按两两上下排版，图片按四宫格排版，输出到 YYYYMMDD--已合并 目录，默认文件名重名时自动追加序号。

使用 poocr 库识别发票并导出 Excel。当用户需要识别增值税发票、批量处理发票文件或提取发票信息到 Excel 时调用此技能。

Read supported mailbox providers such as 126, 163, and Gmail, identify invoice attachments or invoice download links, archive invoices by month, deduplicate by invoice number and amount, and prepare monthly reports plus delivery bundles. Use when OpenClaw needs to sync invoice mail, investigate failed downloads, package a month's archive, or summarize totals and high-value invoices.

Invoice tracker — track sent invoices, flag overdue payments, draft follow-up reminders. Weekly cron or on-demand.
