Typical Failure Patterns in App Development Ordering
Most failures that occur when ordering app development are caused by gaps between the client's expectations and the final deliverables.
Company A (a retail company with 80 employees) ordered development of a customer loyalty points management app with a budget of 5 million yen. However, four months after development began, they were billed an additional 3 million yen because "iOS and Android dual platform compatibility costs," "push notification feature development hours," and "server infrastructure setup" had not been included in the original estimate. Ultimately, the budget ballooned to 1.6 times the original amount, and the release was delayed three months beyond the original schedule.
Company B (a startup) ordered from the lowest-priced development company, but the assigned engineer left midway through and handed off to another person with insufficient knowledge transfer. As a result, code quality deteriorated and serious bugs occurred frequently after launch. Negative user reviews accumulated, and the app store rating fell to 1.8. Ultimately, a complete rebuild was necessary, costing more than twice the original budget.
Company C communicated their requirements verbally without creating detailed specifications. The development company insisted they "built exactly what was requested," while Company C maintained the result was "different from what we expected." The dispute eventually escalated to legal proceedings, ending without either party receiving the completed product or recovering payment.
What these cases have in common is that clients proceeded with contracts without understanding the "invisible complexity" of app development. App development involves many processes including design, implementation, testing, app store submission, and maintenance, each requiring client judgment and approval. When clients order without understanding this complexity, problems inevitably arise.
App Development Cost Estimates and Budget Planning
Ordering without accurate understanding of app outsourcing costs leads to mid-project shutdowns due to budget shortfalls or quality compromises. Development costs are primarily determined by "development type" and "feature scope."
Cost Differences by Development Type
Native apps (iOS-only or Android-only) achieve quality optimized for each platform, but supporting both iOS and Android effectively doubles the development cost. The market rate for a single platform is approximately 1 to 3 million yen.
Cross-platform development (React Native, Flutter, etc.) allows a single codebase to support both iOS and Android, offering 30 to 50 percent cost reduction compared to native dual-platform development. However, implementation precision for platform-specific features (camera, GPS, payments, etc.) may be lower than native.
Web apps (including PWAs) do not require app store submission and offer faster development and update cycles. On the other hand, there are limitations for offline operation, push notifications, and device feature access. Simple functionality can be developed for approximately 500,000 to 1.5 million yen.
Cost Estimates by Feature Scope
Simple apps (member registration, login, information browsing, push notifications only): 1 to 3 million yen
Standard apps (e-commerce features, reservation systems, chat, map integration, etc.): 3 to 10 million yen
Complex apps (payment systems, real-time communication, AI features, external API integration, etc.): 10 million yen or more
Often-Overlooked Cost Items
Beyond development costs, the following expenses are also necessary. App store registration fees (Apple Developer Program: approximately 12,000 yen per year; Google Play: one-time fee of approximately 3,000 yen), server costs (approximately 10,000 to 100,000 yen per month), maintenance and operation fees (15 to 25 percent of development cost per year as a guideline), and design fees (approximately 20 to 30 percent of the total). It is important to set a total budget including all of these in advance.
Practical Steps for Successful App Development Ordering
When systematically organizing app development ordering, the process can be divided into five stages. The key to success is for clients to proactively make judgments and approvals at each stage.
Stage 1: Requirements Organization and Goal Setting (Pre-order preparation period: 3 to 6 weeks)
First, clarify the app development objectives in quantifiable terms. Instead of "improving operational efficiency," set specific goals like "reduce monthly ordering operations from current 40 hours to 10 hours" or "increase customer repurchase rate from current 30 percent to 50 percent."
Next, define in detail the users who will use the app. Specify age, occupation, smartphone proficiency, and usage environment (commuting or desk-based) to the level where you can imagine actual individuals.
Prioritize features into three tiers: "essential features," "nice-to-have features," and "future features." Limiting the initial release to essential features only leads to both schedule adherence and budget management.
Stage 2: Development Company Research and Selection (2 to 4 weeks)
In development company selection, make judgments based on comprehensive evaluation rather than simple price comparison. Evaluation items include:
- Development track record for the same industry and similar apps (3 or more projects)
- Team structure (PM, engineers, and designer allocation)
- Development methodology (agile or waterfall, frequency of progress reporting)
- Specific content of post-release maintenance and operation support
- Emergency bug response system and response time
Obtain comparative quotes from 3 to 5 companies and compare not just prices but the specificity of proposal content. Excellent development companies provide architecture proposals that understand the client's business challenges.
Stage 3: Detailed Specification Confirmation and Contract Conclusion (3 to 4 weeks)
Conduct detailed requirements definition with the selected development company. What is important at this stage is "creating specifications (functional design documents)." Eliminate all ambiguous language and document the operation of each screen and feature in both text and diagrams. Time invested in creating specifications is the greatest investment in preventing rework later.
In contracts, always confirm the following items: definition of deliverables and quality standards, deliverables and approval methods for each process, scope of responsibility and deadline for bug fixes, ownership of copyright and source code, method for calculating costs when specifications change, and handling upon project suspension or cancellation.
Stage 4: Development Process Management (During development period)
After development begins, the client should actively participate in the project. Set up weekly regular reporting meetings to share progress and issues. Ensure confirmation and approval at each development milestone (design completion, screen design completion, feature implementation completion, etc.).
The most important thing at this stage is to "keep specification changes to a minimum." Specification changes during development affect many processes invisibly. When requesting changes, confirm with the development company how the change impacts existing design before making a decision.
Stage 5: Testing, Delivery, and Release (2 to 4 weeks)
Always conduct functionality testing before delivery. Verify all anticipated user operations on actual devices and document bugs and unexpected behaviors. Testing should ideally be conducted on multiple device models for both iOS and Android.
App store submissions have review periods (Apple: average 1 to 3 days; Google Play: several hours to several days). Set a schedule with sufficient lead time before the intended release date and also secure time for responding to review rejections.
Important Points Often Overlooked in Development Company Selection
In app development ordering, there are evaluation points that many clients overlook.
Estimate detail level is the first checkpoint. Trustworthy development companies submit estimates that clearly show hours and unit costs by process and team member. An estimate like "app development, all-inclusive: 5 million yen" is a warning sign. When processes are not broken down, there is a high risk of later being billed for "unexpected work" as additional costs.
Verifying released portfolio projects is also important. Download and actually use the apps listed in the development company's portfolio, evaluating from the following perspectives: operational stability and response speed, UI intuitiveness and design quality, app store review ratings and number of reviews, and last update date (old apps may have discontinued support).
Transparency of communication structure is also an essential confirmation item. Request opportunities to speak directly with actual development staff (engineers, PM) during business discussions. Quality development companies have structures where engineers directly understand client requirements and can speak frankly about technical feasibility.
Source code ownership and transferability should also be confirmed in advance. Some development companies do not fully hand over source code, creating dependency for maintenance services. It is important to explicitly state "complete transfer of all source code and related documentation" in the contract.
Post-release maintenance and operation support structure is also an important decision factor. Specifically confirm OS version update support (Apple in particular has one major annual update), bug fix response speed, and server failure response structure. Ordering from a development company that considers its job done after release leads to difficulties after operations begin.
Preparation Work Clients Should Start Immediately
Even those considering their first app development order can significantly improve success rates through proper preparation.
Start with thorough investigation of competing apps. Download and actually use 5 to 10 apps from competitors or similar services, and organize the excellent features, missing features, and UX problems. This list becomes the starting point for requirements definition and important material for explaining to development companies specifically.
Building internal organizational structure is also essential preparation. App development projects require at minimum: a project manager (a person with decision-making authority), a requirements representative (a person who can communicate business requirements to the development company), and a testing representative (a person who can actually verify the completed product). Ordering without designated staff causes delays in decision-making that stall the project.
Creating wireframes is also effective preparation. Sketch the app's screen layout on paper or in PowerPoint without concern for design quality. Simply illustrating "what appears on which screen" and "where pressing each button leads" is sufficient. This dramatically speeds up alignment of understanding with the development company and also improves estimate accuracy.
Formulating a phased release plan in advance is also important. Rather than aiming for a perfect app at first release, narrow down features using the MVP (Minimum Viable Product) concept. Adding features while observing actual user responses reduces risk in terms of development costs, schedule, and quality.
For detailed budget calculation, it is recommended to calculate the total 3-year cost including: initial development costs, annual server and infrastructure costs, annual maintenance and operation costs, OS update response costs (1 to 2 times per year), feature addition and revision costs (budget based on revenue and usage), and internal staff hours (equivalent personnel costs).
The most important thing for clients to recognize in app development is that "an app is not finished when it is built — it is a product requiring continuous investment even after release." Setting a budget from a long-term perspective including not just development costs but also operation and improvement costs, and building a continuous partnership with the development company, is the key to success.
While taking sufficient time in the preparation stage may appear to be a detour, it is the most reliable method for preventing rework and additional costs during development. Even if requirements definition is delayed by one month, it is far less costly than a three-month delay due to troubles during development.
