商家如何自己零成本免费制作点餐小程序项目完整源码

现在点餐小程序成为餐饮店的标配，顾客只要扫码，即可进入小程序点餐。顾客付款后，后厨自动打印出订单并开始制作。整个过程非常方便流畅，甚至还可以免去收银（或服务）人员。那么，这种餐饮小程序要如何搭建呢？找小程序开发商还是商家自己搭建呢？

外卖行业近几年发展迅猛，微信平台也成为其中的一个主力军，小程序的横空出世，让不少微信外卖平台加入其中，纷纷开发了自己的餐厅点餐小程序

餐厅点餐小程序功能非常方便，对于用户来讲，操作如下：
1.打开自己的微信账号，选择【小程序】
2.点击【小程序】进入，进入餐厅点餐小程序系统
3.选择这家餐厅之后，进入微信授权界面，选择允许
4.进入店内之后，选择外卖字样，可以看到这家店的详细地址和详细联系电话以及营业时间，还有商家的环境
5.选择外卖的界面之后，在左边有一个列表是大分类：如热销、优惠、套餐、主食、配菜、饮料等等
6.点击选择规格之后进入选项中口味的选择：选择好之后【加入购物车】
7.选择【加入购物车】，如何没有其他需要点餐的就可以直接点击【选好了】，还需要选择其他外卖的话都一致加入购物车
8.最后在想【选好了】点击进入【订单提交】，添加好收货地址之后、收货人、联系电话进去付款即可。可选择填写备注，比如口味、偏好等
