FH FluxHarbor Payments Contact desk

About the firm

A small Seoul desk that writes about subscription payments and works on them too.

Seven consultants. One office in Jongno-gu. A weekly editorial brief and a fixed catalogue of service packages we know we can deliver well. Nothing larger has ever sounded like a better idea.

The desk story

We started as the audit team that nobody else wanted to do.

The early engagements were tedious billing audits for subscription businesses too small to have a payments specialist on staff and too large to run on intuition. Nobody else wanted the work, which is how we ended up with a strong opinion about it.

Six years later the practice still revolves around audits. The packages have grown around them: architecture sprints, dunning design, migration programmes. Each one of them began as a chapter of an audit that kept showing up and eventually became its own piece of work.

We are deliberately small.

Subscription payments is a narrow field. The seven consultants on the desk speak to each other every day, which is how we keep the practice consistent. Hiring an eighth would mean changing how we work; we have decided not to, for now.

That choice has a cost. We turn away engagements that would not fit a seven-person desk. We tell prospective clients honestly when the timing is wrong. We refer them to peers in Tokyo, Singapore, and Berlin when we cannot help, and they refer back when the brief is closer to ours.

Working principles

Four house rules.

Be specific.

A vague brief produces a vague engagement. We rewrite the scope until it would survive a finance audit, not a marketing review.

Say no out loud.

When a package is not the right fit we say so before the proposal. The client pays for our judgement, not for our agreement.

Write everything down.

If a decision is not in writing it did not happen. Every engagement leaves a written deliverable that survives the consultant who wrote it.

Charge for the work, not the time.

We quote per package, not per hour. The risk of running over is ours. Our clients get the answer either way.

Timeline

A short history.

  1. 2019

    Desk founded

    Started as a two-person consulting practice above a coffee roaster in Seongsu-dong, Seoul. First engagement: a billing audit for a regional language-learning app.

  2. 2022

    Editorial brief launched

    Spun off the internal Tuesday memo into a public newsletter after readers outside the firm kept asking to be added to the distribution list.

    Centropolis office

    Moved into the current office in Jongno-gu after the seventh consultant joined. Stayed at seven on purpose; we do not plan to scale headcount aggressively.
