我公司现在用linnworks平台通过API,CSV分别对接美国亚马逊，ebay店铺，还有我们自己的购物网站，已实现通过linnworks一键发布产品到各接口，各接口库存即时同步更新，订单统一管理等交易环节的整合。我们现在需要开一个TB店铺，也同样接入这个linnworks平台。要求如下： 等级1：在TB店铺实现现有linnworks对接美国亚马逊的所有类似功能，包括产品上传，订单管理处理，库存同步更新等。 等级2：在TB店铺实现现有linnworks对接美国亚马逊的订单管理处理，库存同步更新功能。 等级3：在TB店铺实现现有linnworks对接美国亚马逊的库存同步更新功能。 等级4:不通过linnworks，利用类似一键复制APP之类的功能实现 美国亚马逊店 跟TB店双向库存同步更新。 本项目目前的可见难点： 1.语言，TB店铺所有生成的CSV或者数据都是中文，而Linnworks， 美国亚马逊店铺都是英文。 2.利用CSV表格发布产品时，美国亚马逊的产品图片可以直接使用网页照片的链接，而淘宝需要先上传到TB空间。 3.需要了解linnworks 跟美国亚马逊店铺，TB店铺的相关一些规则，知识。 对招标伙伴的要求： 有相应的TB店铺API开发经验的，并在了解linnworks平台之后再跟我们联系

定制PrestaShop， 基于1.6版本，UK的英文网站， 大多数功能1.6版本已可实现， 不需要在线付费， 后台基本不用改， 所需四点定制如下 1. 实时更新价格 -已有live xml feed，需要根据feed每过几分钟更新一下产品价格即可 2. 根据公司现有的主网站定制shop的模板， - 只需重用现有的css，layout和图片 3. 产品价格的基础上增加percentage based commission - 类似折扣但是增加一个百分比，比如产品价格是100圆，commission是2%，那么价格应为 100 + 2 = 102 4. 扩展用户注册 - 第一步和现有的prestshop一样 - 第二步要根据公司的用户登记pdf表格增加一些信息 价格可议， 有意者请留skype，QQ 或email
