Why Comparing Web Production Estimates is Difficult

According to a 2023 survey by Web-Kanji, the average web production cost for SMEs is 825,000 yen, with a median of 434,000 yen, showing a nearly two-fold difference. This price gap stems from differences in estimate items, such as the definition of the production scope, the number of design revisions, the inclusion of CMS implementation, and how maintenance costs are factored in.

Even when obtaining quotes from multiple companies, the reality is that simple price comparisons are insufficient because the granularity and terminology of the items differ.

How the New Tool Works

The Estimate Comparison Tool allows users to input the details of up to three quotes, which the AI then standardizes to generate a comparison table.

Input Method

Users input the following items from each company's quote:

Total production cost
Number of pages and unit price per page
Design fees (including conditions for number of revisions)
CMS implementation and customization fees
Presence or absence of responsive design
Post-launch maintenance and operation fees (monthly)
Delivery deadline

Comparison Results

A standardized comparison table for the three quotes
Display of differences in included/excluded items
Degree of deviation from market rates for each item (High/Appropriate/Low)
Advice on missing items that should potentially be included
Total one-year cost comparison including maintenance fees

Five Key Perspectives for Estimate Comparison

Along with the comparison results, the tool also highlights the following perspectives:

1. Production Scope: Confirming not just the number of pages, but the components of each page (forms, maps, videos, etc.)

2. Number of Revisions: The limit on design revisions and additional costs for exceeding them

3. Rights to Deliverables: Ownership of source code and design data

4. Maintenance Fees: The scope covered by monthly maintenance (security updates, text corrections, etc.)

5. Conditions for Additional Costs: Under what circumstances additional estimates will be generated

If you are considering ordering web production, please make use of our Estimate Comparison Tool.
