Work beyond five days Custom quote

Anything that will not fit within five days is quoted separately as full development. If you did a prototype first, its fee is deducted from that quote.

When the scope grows

  1. It grows by the day: KRW 300,000 per extra day, and we tell you how many days are needed before we start.
  2. Beyond five days, it becomes full development with its own quote — and the prototype fee is deducted.
  3. New features, external integrations and extra screens are quoted as additional work and start only after you agree.
  4. One feedback round means one batch of comments sent together. Extra rounds are billed by the half day (KRW 150,000).
  5. Bugs within the agreed scope are fixed free of charge after delivery.
  6. External costs such as AI service fees or servers are passed on at cost.
  7. We issue tax invoices and contract directly, with no platform fees.

How it works

  1. 1

    Inquiry · scope

    Tell us what you want to build, and we agree on the scope and how many days it needs.

  2. 2

    1–5 days of work

    We focus only on the agreed scope and turn it into a working screen.

  3. 3

    Demo · feedback

    Click through it with sample data; we apply one round of feedback.

  4. 4

    If the direction is right, we send an estimate for full development — with the prototype fee deducted. You are also free to stop here.

FAQ

How much does it cost?

1 day from KRW 300,000, 2 days from KRW 600,000, 5 days from KRW 1,500,000 (excl. VAT, tax invoice issued). Anything beyond five days is quoted separately as full development.

Can the prototype go straight into production?

It is for demonstration and validation. For production use, full development adds the stability and security it needs.

Is the material I send kept safe?

Under a confidentiality agreement, and only within the scope you agree to.
