Work excluded from this example
A complete redesign, payment-provider replacement, server migration, lost-data recovery and new features require separate estimates. Building a new app has a different scope from this maintenance example.
Prepare a new-app estimate
List user and admin roles, core screens and error states, payment, notification and map integrations, target platforms, design readiness and existing data or migration needs.
Agree separately on hosting, store, domain and third-party fees, acceptance criteria, handover and ongoing maintenance. New-app price bands require a defined functional and acceptance scope.
Frequently asked questions
Does ₩5,500,000 cover a new app?
That is the VAT-inclusive preliminary quote for repairing an existing website. New apps need a separate estimate based on workflows, integrations and target platforms.
When do the 15 business days start?
In this example, after receiving materials and access. It is not a new-app development timeline or a store review estimate.
What happens when scope changes?
Changes are separated from the agreed scope and assessed for cost and schedule impact. Work with evolving scope can be discussed as weekly time-based engagements.
Is ongoing maintenance included?
Defect correction differs from ongoing operations and new features. The contract separates correction periods, support channels, update cadence and recurring fees.
