From the teams we've worked with
Supamas Phetkrachang
Operations Manager · Bangkok
We'd been producing a weekly operations summary for two years, but no one was sure what it was actually meant to tell us. The Data Clarity Session was uncomfortable in a useful way — Pattaraporn asked questions we'd been avoiding. We came out with four measures we now track consistently, which is a significant change from fourteen.

Ratchanon Klomklieng
Finance Director · Chon Buri
The Reporting Setup Project took about five weeks. Krit was methodical and didn't rush the design phase. The final reports are simpler than what we had before — less data per page, but it's the data that actually matters. My team spends maybe two hours a week less on assembly than before, which adds up.

Narathorn Wisuttipat
Managing Director · Bangkok
We've been on the Analytics Advisory engagement for eight months. What I find most useful is the written note after each session. It's not a transcript — it's a one-page summary of what we noticed and what questions remain. I refer back to them when reviewing performance at the end of each quarter.

Arisa Tangtrongchitr
Head of Strategy · Bangkok
Our team had never worked with an external data advisor before, so I wasn't entirely sure what to expect from the session. The pre-session questionnaire helped me think through what we were actually trying to solve. The session itself was practical rather than theoretical — we spent most of it looking at what we collect and what we don't.

Patcharapong Srisuwan
Regional Controller · Bangkok
The source documentation that came with the reporting project has been more valuable than the templates themselves. When our finance assistant changed, the new person was able to follow the documentation and maintain the reports without needing to call Quillstone. That's exactly what we needed — a structure that doesn't depend on specific individuals to keep running.

Kanchana Nilwong
CEO · Samut Prakan
I appreciate that the advisory engagement doesn't pressure us to add more metrics each month. In practice, we've reduced the number of figures we review at our leadership meetings. That's the opposite of what I expected — I thought an analytics advisor would add complexity, not remove it.

Detailed client journeys
Three accounts describing the initial situation, the work we did, and what changed as a result.
From fourteen weekly figures to four useful ones
The Situation
The operations manager was producing a 14-metric weekly summary that took four hours to assemble. Attendance at the weekly review meeting had been falling for months because participants felt the report didn't help them make decisions.
What We Did
We ran a Data Clarity Session to identify which metrics connected to actual decisions, then built a Reporting Setup Project to redesign the weekly summary. The new format had four figures, each tied to a specific question the team needed to answer each week.
What Changed
Assembly time dropped from four hours to around 45 minutes. Meeting attendance improved within six weeks. The operations manager described it as "the first time in two years people actually read the summary before the meeting."
Building a data habit from a standing start
The Situation
A regional firm growing from 12 to 35 staff had no consistent way to track whether growth was sustainable. The managing partner used a mix of gut feel, accounting exports, and occasional external benchmarks, but none of it formed a coherent picture.
What We Did
We started with a Data Clarity Session, then moved the client onto the Analytics Advisory engagement. Over the first six months, we helped them identify five key indicators and develop a monthly review rhythm that fit around the managing partner's schedule.
What Changed
After twelve months, the client described having "a much clearer sense of which parts of the business are performing well and which aren't." Two decisions about staffing were directly informed by patterns identified in the monthly advisory sessions.
Consolidating reporting across two facilities
The Situation
A mid-size manufacturing group was running two facilities with separate reporting processes. Monthly consolidation was taking the finance team most of a working day, and the figures were still inconsistent enough that the CFO regularly questioned the numbers in management meetings.
What We Did
We mapped how each facility collected and categorised data, identified four definitional inconsistencies, and built a shared reporting structure both teams could feed into. The source documentation was the most detailed we'd produced for a single project — it ran to 22 pages.
What Changed
Monthly consolidation dropped from a full working day to around two hours. The CFO's questions at management meetings shifted from "are these numbers correct?" to "what does this trend mean?" — which is a more useful place for leadership time to be spent.
