Using
Momen · full-stack no-code platform
to build
a simple payment-enabled business website
PROJECT OVERVIEW
What this app does
A basic public website for a business that uses a .com domain and accepts payments through Razorpay. Visitors can browse available offerings, proceed to checkout, and see their order status, while the site administrator can manage offerings and review customer orders. The design is based on the stated expectation of roughly 100–200 page views per day.
As a visitor, I want to browse active offerings so that I can decide whether to proceed to checkout.
As a customer, I want to pay for a selected offering through Razorpay and check the resulting order status.
As a site administrator, I want to create and update offerings so that customers can see what is available.
As a site administrator, I want to review customer orders and their payment statuses.
The following user counts are projected totals after one year of growth
1
site_admin
The site owner or administrator who maintains offerings and reviews customer orders.
1199
public_visitors
Anonymous visitors and customers who browse the public website and may proceed to checkout.
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
Razorpay checkout requires payment capabilities available in PRO.

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 $99/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 ≈ $330.26/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
200
Total users
We assume this is a small company or service website rather than a high-growth consumer platform because the description calls it a basic website and gives modest daily page-view expectations. With no order-throughput figure or explicit account count, the company-site and lead-capture category anchor is 200 registered accounts; this is a planning reference, not a prediction of daily activity. If the business needs many customer accounts or has a larger staff, this estimate can be adjusted.
225
Data retention period
We assume this website will build its order and offering data gradually as it operates because no launch migration or pre-existing dataset is described. A standard linear-growth operating window is therefore appropriate for this small web product. If the site launches with a full pre-existing dataset or has a concentrated launch period, this parameter can be adjusted.
Daily Public Browsing and Checkout Scenario
Daily Public Browsing and Checkout Scenario
We assume public visits and checkout attempts are spread across the day rather than concentrated around a scheduled external event. A ten-hour active period represents ordinary public-site use without treating each page view as a separate synchronized rush. Browsing and payment are separate purposes because most visitors only browse, while a smaller group proceeds through checkout. This routine scenario occurs daily, so its monthly frequency follows the ordinary 30-day month assumption.
