Many projects decide to build an app before checking whether an app is really needed. This guide unpacks the differences between native apps, responsive websites, and PWAs, the situations each one suits, how costs shift after launch, and the five judgment errors clients make most often.
Fixed scope at a fixed price, or agile iteration? The difference is not which one is more modern, but who absorbs the risk of a bad estimate. This guide unpacks the trade-offs of both contract models, how changes get handled, how a hybrid is structured, and the role and time a client has to commit inside an agile project.
When testing shows up as a line item on a quote, the first instinct is often to cut it. This guide explains in plain terms what unit, integration, and end-to-end tests actually do, what automation means for the long-term cost of changes, what is worth testing and what is not, and how to confirm at acceptance that your vendor really did the work.
You want to move your courses online — should you use an existing platform or build your own? This guide breaks down the core features of a course platform: video playback, progress tracking, quizzes, certificates, payments, and discussion. It compares packaged platforms and custom builds on revenue share, data ownership, and brand, and explains how to approach video protection, bandwidth costs, and student personal data.
Your product has launched — which direction should it grow in? This guide explains how to organize the three sources of feedback (support, data, public reviews), how to rank feature requests on value, cost, and risk, how to set a release cadence, how to balance technical debt against new features, and how to structure a long-term arrangement with an outsourced team.
Social login looks like one extra button. In practice it reshapes your signup flow, your member data, your support workload, and your account security. This guide explains the problems it solves, how to design it alongside your own accounts, what data you can and cannot obtain and how consent should be handled, where account merging and recovery most often go wrong, and what SSO means inside a company, in plain terms.
You want to add an AI assistant or automatic summaries to your own systems, but where do you begin? This guide covers the four AI features companies actually use, the data and process conditions you need in place first, the trade-off between rule-based and generative approaches, how to control accuracy and privacy risk, and why staged validation beats building everything at once.
A finished app is not the same as an app that can be published. This guide covers the developer accounts, privacy policy, screenshots and copy, and testing scope you need before submission, the categories of common rejection reasons and the logic behind them, and how to plan release cadence, review replies, and version updates afterwards — written so a non-engineering owner can track progress.
An online booking system looks like it only has to let customers pick a time slot. What it actually has to handle is slot rules, staff and resource scheduling, reminders, cancellations, and deposits. This guide covers which industries need one, the trade-off between existing platforms and custom development, the essential feature list, and how to design integrations with LINE and Google Calendar as well as measures that reduce no-shows.
A LINE bot is more than an auto-reply. This guide explains what becomes possible once a LINE Official Account is connected to your own systems, how to choose between rule-based flows and AI conversation, what you need to prepare before development starts, and the common misconceptions and platform rules to watch — written so that non-engineers can judge feasibility.
The most common argument at the acceptance stage of a software project is whether the work counts as finished. This guide explains how acceptance criteria should grow out of the requirements document, how to write test cases, who should actually do the testing, how to grade defects, and how acceptance, payment milestones, and the post-launch warranty period should be arranged.
Where do you start when orders, stock, member records, payments, CRM, and LINE all need to talk to each other? This guide explains what an API is in plain terms, sets out the common types of integration requirement, explains why integration projects habitually overrun, provides the audit checklist to complete beforehand, covers what acceptance testing and monitoring should look for, and identifies when to bring in a technical consultant before writing any code.
Software projects rarely run late because engineers write code slowly. This guide breaks down the four real causes — requirements that keep shifting, decisions that stall, third-party dependencies nobody controls, and badly underestimated integration and testing — then covers what the client side can do, how to build buffer into an estimate, and what to do once a project is already late.
What does it really take to build an app? This guide breaks down the trade-offs between native, cross-platform, and PWA approaches, explains where the cost actually sits — back end, design, testing, and store submission — walks through the rhythm of a development timeline, covers the costs that continue after launch, and shows how phased development controls risk when the budget is limited.
The most common mistake in choosing a software development company is comparing quotes alone. This guide collects the specific questions to ask when evaluating a vendor, how to read a portfolio and a development process rather than just the visuals, the contract terms that matter most — source code ownership, acceptance criteria, change pricing, warranty, and confidentiality — and the red flags worth walking away from.
The most common misunderstanding about an MVP is treating it as a crude version with half the features removed. This guide explains what an MVP is actually there to validate, how to decide what goes into the first version and what stays out, why technology choices should be good enough and replaceable, when a rewrite is genuinely warranted, and what to watch when an outsourced team builds your first version.
