Ask a team how long its paperwork takes and you'll usually hear the typing time. It's the visible part. It's rarely the biggest.
Four costs, not one
Typing. Getting each document into the spreadsheet.
Checking. A second look, because everyone knows typing goes wrong.
Correcting. Finding the line that made a total disagree — often weeks later, when nobody remembers the receipt.
Chasing. Asking for the receipt that never arrived, the photo that was too blurry, the screenshot in someone else's chat.
A rough sum you can do yourself
An illustration, not a benchmark: 400 receipts a month at two minutes each is about 13 hours of typing. Add a second look at each, and the time spent fixing the ones that don't add up, and the real figure is easily higher.
Put in your own numbers: documents per month, minutes per document, how often something needs fixing, and how long a fix takes.
What changes when AI does the reading
The work doesn't disappear; it changes shape. Typing goes. Checking becomes a glance at the photo beside the figures. Errors are flagged when documents come in, not when a total fails to match.
If your sum comes to more than a day a month, it's worth a conversation.
问一个团队处理单据要多久，得到的答案多半只是打字的时间。那是看得见的部分，却很少是大头。
成本不止一项，而是四项
录入。把每张单据打进表格。
核对。再看一遍，因为谁都知道手打难免出错。
改错。找出导致合计对不上的那一行，往往已是几周之后，谁也记不起那张收据了。
追单据。催那张迟迟没交的收据，要那张拍糊了的照片，找那张躺在别人聊天记录里的截图。
一笔自己就能算的账
以下仅为举例，并非行业数据：每月 400 张收据，每张 2 分钟，光录入就要约 13 小时。再加上逐张复核、修改对不上的部分，实际耗时只会更多。
不妨代入你自己的数字：每月多少张单据、每张几分钟、多久出一次错、每次改要多久。
交给 AI 识别之后
工作不会消失，只是换了形式：录入没有了；核对变成对照原图扫一眼；错误在单据进来时就会标出，不必等到合计对不上。
如果算下来每月超过一天，就值得聊一聊。
