PROJECT OVERVIEW

What this app does

这是一个面向约2000名批发客户的在线选品网站，集中展示约10000个SKU，供客户每天浏览、筛选并查看商品详情。客户可以保存自己的选品结果和意向数量，目录管理员负责维护商品分类、SKU资料、批发信息与商品主图。

作为批发客户，我可以按分类、名称或SKU筛选商品目录，以便日常选品

作为批发客户，我可以查看单个SKU的商品详情、批发信息和主图

作为批发客户，我可以把SKU加入选品清单并填写意向数量

作为批发客户，我可以查看、修改或移除自己的选品记录

作为目录管理员，我可以创建和维护商品分类及SKU资料

作为目录管理员，我可以查看现有商品并更新其资料、主图和可见状态

The following user counts are projected totals after one year of growth

catalog_managers

负责创建分类、录入SKU并维护商品资料和可见状态的内部人员。

2000

wholesale_customers

登录后每天浏览SKU、查看商品详情并维护个人选品清单的批发客户。

COST BREAKDOWN

How your requirements become a plan and a price

Momen doesn't give a vague quote: it first sizes the project's actual demand for each capability and resource, then costs each item out. The numbers in the 'Project demand' column below — their scale assumptions and derivations — are detailed in Scale & sizing

WHY MOMEN

Your options for this project

In the table below, the 'monthly infrastructure' for the self-built / AI routes is derived from the AWS list prices shown below, sized against this project's actual usage. Figures cover infrastructure and operations only — AI usage is billed separately and excluded here, so they don't match the $111.92/mo all-in above.

Infrastructure cost is unavoidable

Servers, databases, traffic and storage are inherent infrastructure costs for this project — you pay them whether you outsource, use Cursor or Lovable, or build it yourself (self-built runs ≈ $403.29/mo at AWS list prices, often more), on top of the dev and ops staff you'd need to hire. Momen bundles all of it into $0/mo all-in and removes the need for an ops team.

Vibe-coding speed + a production-grade backend

The frontend can be generated with AI tools (Cursor, Lovable, etc.); the hard part is the backend — auth, database, scaling, data security and ops. Momen delivers a production-grade backend as a BaaS: keep the vibe-coding speed on the frontend, while the backend runs on proven infrastructure — reliable, with no self-hosting or ops.

SCALE & SIZING

What scale this estimate assumes, and how the numbers are derived

Cost depends heavily on usage volume. First see the key assumptions and business scenarios this estimate uses, then the full calculation derived from each scenario for every resource — all adjustable to your real situation

2005

Total users

我们假设系统包含用户明确给出的2000个批发客户账户，并需要少量目录管理员维护一万个SKU，因为没有后台维护角色就无法形成商品数据的创建与浏览闭环。这里采用5个管理员账户作为小型批发团队的典型配置，因此稳定运行时按2005个注册账户建模；如果管理员人数已经包含在2000人内，该参数可以调整。

365

Data retention period

我们假设该网站上线时会带入现有的约一万个SKU和两千个批发客户，因为这更像成熟批发业务的数字化目录，而不是从零积累的新产品。按带有完整既有数据的上线方式，使用完整年度的数据积累窗口较为典型；如果实际是从零冷启动，等效天数可以相应调低。

Core business scenarios

Daily Customer Catalog Browsing

times/month

0.36 req/s

Peak load

We assume catalog browsing is spread across an eight-hour business day because buyers enter according to their own purchasing schedules rather than a shared external signal. The scenario occurs every calendar day because the project states that customers browse daily. Category navigation, catalog filtering and product-detail inspection are separated into distinct purposes because each represents a different user intention and has a different participation level. If the business operates only on weekdays or has a narrow ordering rush, the frequency and duration can be adjusted accordingly.
