出海 SaaS/APP 怎么定价?手搓了个沙盘模拟工具 最近在和朋友一起看了下工具类产品的报表 发现有一些持续创收的产品,其实最终看下来,还是倒贴的 因为一开始就自己俩人捣鼓,也不懂专业的财务知识,后面慢慢才发现会存在 gap 值 这一些 gap 值的原因就是各种佣金、消费税和预扣税等等 而且这个和开发者账号主体以及产品推广的地区还都有关系 捋清楚之后,自己也做了这个工具 也希望有专业的小伙伴可以给点宝贵意见哈~ https://trueproceeds.com/

Built a DIY calculator site in a weekend — betting on "boring tools" over content After my last project (an AI debate platform) got rejected by AdSense for "low value content," I went the opposite direction: no content treadmill, no AI features, no backend. Just genuinely useful calculators. studandslab.com — 10 free calculators for woodworking and home projects (board feet, stair stringers, concrete, drywall). Everything runs client-side, so hosting is free and every visitor costs me $0.
