KoiQuanta for Koi Dealers: A Dealer Case Study

By KoiQuanta Editorial Team|Updated Mar 2026

A typical mid-sized dealer spends 5-8 hours per week on manual quarantine record keeping. That's 260-416 hours per year on administrative work that produces records you can't search, can't analyse, and can't share professionally with buyers. This is the problem one UK-based koi dealer solved when she moved her operation to KoiQuanta.

KoiQuanta's dealer tier replaces the multi-spreadsheet system most dealers use today. No competitor was designed for dealer operations at scale.

TL;DR

That's 260-416 hours per year on administrative work that produces records you can't search, can't analyse, and can't share professionally with buyers.
At any given time, he has 40-80 fish moving through quarantine, grow-out, and display holding.
The setup took approximately 4 hours spread over two days - entering his existing fish as the starting inventory and configuring his standard quarantine protocols.
Three out of his first six quarantine batches under the structured protocol had at least one fish showing parasite indicators on the day-21 observation that he'd have dismissed without the protocol prompt.
James searched the fish by its variety and arrival date in KoiQuanta, pulled up the full quarantine record, treatment history, water quality during quarantine, and post-discharge observations in approximately 90 seconds.
For every fish sold at £200 or above, the buyer receives a PDF export of the quarantine record showing the dates, treatments, parameter readings, and discharge health status.
He's raised prices on documented stock by 15-20% since adding the certificates.

The Starting Point: A Well-Intentioned System That Wasn't Working

James runs a mid-sized koi dealership in Yorkshire, sourcing fish from Japan twice per year and from domestic breeders throughout the season. At any given time, he has 40-80 fish moving through quarantine, grow-out, and display holding. He's been in the trade for nine years and takes quarantine seriously.

Before KoiQuanta, his system was:

A main spreadsheet for fish inventory (name, variety, size, purchase date, price)
A separate notebook per quarantine cohort for treatment records
A paper log for daily feeding and observation
Water parameter readings in a third notebook
Post-sale records in his accounting software

The system worked in the sense that he knew where his fish were and had a record of treatments. But searching it was difficult. When a customer called about a fish they'd bought six months ago and reported an issue, James would have to pull three different sources of records to reconstruct that fish's history. It took 20-40 minutes per inquiry.

More significantly, he had no way to know if a disease pattern was emerging. When he had two fish with ulcers in different quarantine cohorts in the same month, he didn't connect them. They'd come from different batches and were recorded in different notebooks. A year later, reviewing his records to prepare for a DEFRA inspection, he realised three separate cohorts from the same Japanese supplier had shown elevated bacterial issues. He'd been rebuying from that supplier.

The Transition

James started the KoiQuanta dealer tier in January of the previous year. The setup took approximately 4 hours spread over two days - entering his existing fish as the starting inventory and configuring his standard quarantine protocols.

He made one deliberate decision at setup: he would enter every piece of data once rather than maintaining parallel paper records. If it wasn't in KoiQuanta, it didn't happen. The discipline of single-entry record keeping eliminated the maintenance burden of his previous multi-system approach.

The first month was the adjustment period. Logging observations on a phone app while standing at the tank felt unfamiliar. By month two it was routine - less time per observation than writing in a notebook because the app structure meant he only had to record deviations from normal rather than repeating the same "eating well, no signs" entry manually.

What Changed in the First Three Months

Quarantine compliance improved. With automated protocol reminders, James stopped skipping the day-21 praziquantel re-dose when fish looked healthy and he had other priorities. Three out of his first six quarantine batches under the structured protocol had at least one fish showing parasite indicators on the day-21 observation that he'd have dismissed without the protocol prompt.

One significant disease interception. In his second month on the platform, a batch of seven Japanese fish arrived in early March. All looked well on arrival. The KoiQuanta protocol scheduled temperature range monitoring and KHV observation windows. By day 14, two fish were showing subtle gill movement abnormality and reduced appetite - signs he'd noticed but might have attributed to the import stress without the systematic observation log showing normal appetite in the other five fish. He had the affected two fish tested by a fish vet. The results came back negative for KHV but positive for bacterial gill disease. Treatment resolved the issue before it spread within the cohort or reached his display stock.

Record search time went from 20-40 minutes to under 2 minutes. A buyer called about a fish purchased 8 months earlier. James searched the fish by its variety and arrival date in KoiQuanta, pulled up the full quarantine record, treatment history, water quality during quarantine, and post-discharge observations in approximately 90 seconds.

What Records Did KoiQuanta Replace?

The three notebooks and the main inventory spreadsheet have been replaced entirely. He now uses:

KoiQuanta for all fish records (inventory, quarantine, treatment, observations, water quality, sales records)
His accounting software for invoicing and financial records only (KoiQuanta handles the fish-specific transaction data)

The paper notebook he used for daily quarantine checks sits empty in a drawer.

The Customer Trust Effect

Four months into using KoiQuanta, James added quarantine certificates to his sales process. For every fish sold at £200 or above, the buyer receives a PDF export of the quarantine record showing the dates, treatments, parameter readings, and discharge health status.

Initial buyer response was notable. Several buyers specifically commented on the documentation. One buyer who'd purchased from him previously said it was "exactly what I'd want to see from every dealer." Two buyers who'd never purchased from him before mentioned that the documentation standard was the deciding factor in choosing him over another dealer offering similar fish.

He's raised prices on documented stock by 15-20% since adding the certificates. He attributes roughly half of this to improved fish quality from better quarantine protocols, and half to the documentation premium buyers demonstrate willingness to pay.

Did the Dealer See Fewer Disease Losses After Using KoiQuanta?

Direct comparison is complicated because the variable is hard to isolate - James also changed his quarantine duration from 4 to 6 weeks at the same time. But the combination of longer quarantine, structured protocol, and systematic observation produced measurable changes:

Zero post-sale customer complaints about disease in the 14 months since adoption (previous 14-month period: four complaints, two requiring fish replacement)
Three disease events caught in quarantine before they reached display stock (previous comparable period: one display pond disease event requiring whole-pond treatment, estimated cost £400 in medication and fish loss)
One supplier relationship terminated after KoiQuanta analysis revealed elevated disease rates in three consecutive batches from that source

Frequently Asked Questions

How does a koi dealer use KoiQuanta?

A koi dealer uses KoiQuanta to manage every fish through its full lifecycle in the operation: logging fish on arrival with source and purchase data, running structured quarantine protocols with daily observation logging and treatment scheduling, tracking water quality in quarantine and display holding tanks, recording sales with buyer information, and generating quarantine certificates for buyers. The dealer tier supports multiple simultaneous quarantine batches and provides analytics showing disease rates by supplier source, season, and batch - the analysis that's impossible with paper notebooks or spreadsheets. Record search takes seconds rather than 20-40 minutes for customer inquiries.

What records did KoiQuanta replace for a koi dealer?

KoiQuanta replaced a main fish inventory spreadsheet, multiple per-cohort quarantine notebooks, a daily observation paper log, and separate water parameter notebooks - four separate record-keeping systems that couldn't be cross-referenced without manually reviewing each. All fish-specific records are now in a single system: inventory, quarantine history, treatment records, water parameters, behavioural observations, and sales records. The only external system maintained is accounting software for invoicing. Single-entry record keeping eliminated the maintenance burden of maintaining parallel systems.

Did the dealer see fewer disease losses after using KoiQuanta?

Yes. In the 14 months since adoption: zero post-sale customer complaints about disease (compared to four in the previous 14-month period), three disease events caught in quarantine before reaching display stock, and one high-risk supplier identified and removed from the sourcing list. The combination of structured 6-week quarantine with mandatory protocol steps, daily observation logging, and systematic analysis of disease rates by source and season produced outcomes that weren't achievable with the previous ad-hoc recording approach.
