老板一开始看不上网店的三瓜两枣，渐渐的也刮目相看，因为做toC生意的不用垫资，都是客户预付款，在我老婆的忽悠下甚至还能为设计师争取一笔设 计费，最重要的是随着网店销售规模的升级，自然流量和回头客也越来越多，生意规模以极快速度增长，公司团队士气高涨。 结果这时候出了个事，我老婆怀孕临产了，要休息三四个月，运营网店的事需要找人接手。当时店长类型的人才月薪行情是12000-15000，他们老板不舍 得这钱，只愿意花6000请了个人，结果便宜没好货，网店数据一落千丈，等我老婆生完孩子回来每个月销售额跌回两三万了。 昨晚有读者留言说不懂C\G\B生意模式。c是Consumer，指客户都是广大老百姓；g是Government，指客户主要来自政府订单，b是business，指客户主要是 企业。 我写文章为了降低阅读门槛，通常不写简称，昨晚咱不是有拼多多广告嘛，为了通过审查，像"政府"这类敏感词就用简写替代了。 to C\ to G\toB是三 种完全不同的生意形态， 我讲个 和我老婆相关的故事你们感受一下。 她以前在一家做导视牌的小公司上班，专门给市政做路牌，给商场做（洗手间、电梯、进出口等）指引标识。这就是典型的toG和 ...
