This study is a record of one engagement, in one market, at one budget. The full account of the work, and any figures it produced, is written up below — not a forecast for yours.
What would this look like on your account?
Different market, different budget, different numbers. The first call is where we work out whether the same approach fits yours at all.

The case study
The Challenge - Outgrowing Google Sheets
Sell My Car Australia had been operating for years using Google Sheets to manage incoming vehicle leads. At the beginning, it worked. As lead volume grew into the thousands, the spreadsheet became harder to manage.
Filtering by brand, price, or location was painfully slow across thousands of rows.
Sorting hot vs cold leads required manual work and constant attention.
Tracking status changes caused errors. Team members overwrote data regularly.
Notes were scattered or missing. No real visibility across the sales pipeline.
With over 2,000+ leads active at a time, even simple tasks like "show me all Mazda leads in Adelaide under $30,000" became time-consuming.
The founder needed something better - without hiring a full internal tech team. That is when they came to SoudCoh.
The Objective
Build a secure, simple and powerful internal tool that would:
The goal was not just software. The goal was control, clarity and speed.
The Solution - A Custom Lead Management Web App
SoudCoh designed and built a fully customised internal dashboard tailored specifically to Sell My Car Australia's workflow.
1. Real-Time KPI Dashboard
We created a clean executive dashboard that instantly shows Total Leads, Average Asking Price, Average Odometer, Hot/Warm/Cold leads by sentiment, Leads by Brand, and Leads by Location. This gives the founder a clear operational snapshot in seconds.
2. Advanced Filtering System
Instead of manually scanning spreadsheets, the new system allows filtering by Brand, Lead Status (New, Contacted, Inspecting, Negotiating, Purchased, Rejected), Selling Sentiment (1-Very Low to 4-High), Odometer Range, Asking Price Range, Quick Hot/Warm/Cold filters, and search by name, phone or vehicle. This turns hours of sorting into seconds.
3. Structured Lead Database
Each lead now has contact details, vehicle information, asking price, odometer, registration, location, status, sentiment score, internal notes, and message history. Everything lives in one clean interface.
4. Lead Detail Panel with Status Workflow
Clicking a lead opens a side panel showing full vehicle information, sentiment indicator, lead status buttons, notes section (auto-save enabled), and message history. Status updates happen with one click. No more spreadsheet dropdown errors.
5. API Integration
The system connects directly to Sell My Car Australia's existing API. That means leads sync automatically, no manual imports, no CSV uploads, no copy-paste workflows. The business now runs on live data.
The Results
Significant reduction in time spent on manual data management and lead sorting.
Lead response time improved with instant access to structured data and one-click status updates.
No more spreadsheet conflicts or team members overwriting each other's data.
Clear visibility across the entire sales pipeline with real-time dashboards.
Faster identification of high-intent sellers through sentiment scoring and quick filters.
Most importantly, the founder regained time to focus on growth instead of admin.
Why This Matters
Many Australian businesses still rely on Google Sheets for operations. Spreadsheets are powerful - until they become fragile. Once your data exceeds a few hundred rows, spreadsheets stop being a tool and start becoming friction.
A custom internal web application solves that by structuring your workflow, reducing manual effort, preventing human error, creating visibility across your business, and enabling automation.

That is one account. Yours is a different one.
We read your ads, your search presence and your tracking the same way this one was read, and tell you what we would change first.
What every number on this page actually means.
Marketing words get used loosely, and a loose word can make a small result look like a big one. Here is exactly what we mean by each of them.
- Conversion
- One real action by one real person: a phone call that lasted long enough to be a conversation, a submitted enquiry form, a booking, or a purchase. Not a page view and not a form that merely loaded.
- Cost per job · cost per lead
- The advertising money spent, divided by the number of those actions. It is the only figure that tells you whether the advertising is worth doing, which is why we publish it next to the count.
- Conversion rate
- The share of people who clicked the ad and then did the thing. A high click count with a low conversion rate usually means the ad and the page are promising different things.
- Ad spend
- Money that went to the advertising platform, not to us. Our management fee is separate and is never included in a cost-per-job figure, because mixing them would flatter the number.
- The measurement window
- The dates the figure covers, named every time. Where a study covers a launch, the clock starts the day campaigns went live — not the day the graph started looking good.
- A starting point
- Where a study knows what a figure was before the work began, that number is printed next to the one it became. Where the account had no history to compare against, the result is printed on its own rather than measured from a number nobody recorded.
- Qualified lead
- An enquiry that matched the service and the service area, so it was worth someone picking up the phone for. Where a study says qualified, somebody checked.
- An anonymised client
- Government, council and cultural-institution engagements are published as sector and jurisdiction only. The work and the measured outcome are described in full; the organisation is not named.
One more, because it matters most: nothing on this page is a guarantee. It is a record of what happened on one account, in one market, at one budget.
This page exists because of two of the six stages.
Compound is how our team works on any account — six stages every change passes through. Two of them are why there is anything honest to publish.
Meter
If it can't be measured, it doesn't get bought.
Before a dollar moves, every action worth money to the business is tracked as itself — calls, forms, bookings, purchases — with values attached. Without that stage there is no honest number to publish afterwards.
Ledger
Every change we make becomes a record you can open.
Every change lands in a dated record as it happens — what was added, what was stopped, what was rewritten and what it cost. Writing this page afterwards was reading a file, not reconstructing a memory.
What actually happens after the first call.
No mystery and no lock-in before you have seen anything. This is the sequence every account on this site went through.
- The call
Thirty to forty-five minutes, free
What you sell, who buys it, and what one customer is worth to you. No deck. You leave with a real number for your situation rather than a range.
- Week 0
The audit
We open your account — or your competitors' ground, if you do not have one yet — and write down every leak we can find. That list is yours whether or not you work with us.
- Week 1
The build
Everything the account needs before it can spend a dollar: what it will bid on, what it must never pay for, the ad copy, the assets, the landing pages and the tracking. A second person checks all of it before anything is live.
- Day one
You press go
Campaigns are created paused, every time, so you can read the whole build first. You activate when you are ready, not when we are.
- Days 1–14
The clean
The busiest fortnight your account will ever have. Search terms read daily, waste negated, early winners promoted, ad copy iterated against what is actually being served.
- From there
Rhythm
Weekly optimisation, reporting on a fixed cadence whether the news is good or bad, and a proper conversation each quarter about where the next block of budget should go.
Before you ask us anything
Here is what everybody asks first.
The questions this raises.
Whether the figures are real, how they were measured and over what length of window, what it costs, and whether any of it would hold for your business.
The first call is free and there is no deck.
Book a callAre the figures in this case study real?
Yes. Every number on this page was read out of the client's own advertising account and is printed here exactly as the study publishes it, beside the period it covers. The dashboard and ad images are screen-grabs of that account rather than recreations. If one of these figures matters to your decision, ask about it on the first call and we will walk you through where it came from.
How were these numbers measured, and over what window?
Every figure on the page is printed beside the period it belongs to. We publish the LENGTH of a measurement window and the year, and withhold the exact dates — when a client advertised, and how their trading calendar looks, is their commercial information rather than ours. A conversion means one real action by one real person: a phone call that lasted long enough to be a conversation, a submitted enquiry form, a booking, or a purchase. Not a page view, and not a form that merely loaded.
Would this work for my business?
We cannot promise you the same numbers, and nobody honestly can. What this page tells you is what was achievable in that market, at that budget, for that service. Your competition, your service area, your margins and what one customer is worth to you all move the answer. On the first call we build the picture from your figures rather than someone else's, and if the honest answer is that this channel is wrong for you right now, we will say so.
Why does this study show a result but not a starting point?
Because in most of these engagements there was nothing reliable to start from. A brand-new advertising account has no history, and a business that was tracking enquiries on paper or in a spreadsheet has no comparable figure either. Where a real before-number exists we print it next to the after-number, so you can see the movement rather than take our word for it. Where it does not, we print the result on its own. Back-solving a starting point from a percentage would make the page look better and mean less.
Would my business get the same result?
We cannot tell you that, and nobody honestly can. What this page tells you is what was achievable in that market, at that budget, with that service. Your competition, your service area, your margins and what a customer is worth to you all move the answer. On the first call we build the picture from your numbers rather than from someone else's, and if the honest answer is that this channel is wrong for you right now, we will say so.
How much would this cost to run?
Two separate numbers. Your ad spend goes to the platform, and what it needs to be depends on how competitive your market is and how many jobs you want — the smallest companies we work with invest a minimum of A$3,000 a month, and our largest clients run multiple eight figures a month across paid channels. Our management fee is separate and scales with the work. The first call is free and you leave it with a real figure for your situation.
How quickly could we start seeing enquiries?
It depends on the channel. Paid search meets demand that already exists, so calls and forms can arrive within hours of launch, and the first two to four weeks are an optimisation period where waste is cut daily. Most accounts settle into their best rhythm around 60 to 90 days. SEO, content and brand work run on a much longer clock — months rather than weeks — and we will tell you which one your situation actually needs.
Am I locked into a long contract?
No long-term lock-in. We would rather keep the work because it is producing than because a contract says you have to stay. What we do ask for is enough runway to be fair to the account — a campaign judged on its first ten days is being judged during the part where we are still cutting waste out of it. Terms are put in front of you in plain English before anything is signed.
More accounts, same discipline.
Studies from the same kind of work, so you can see how the pattern holds across different businesses.

The work that produced this.
Everything above was delivered by one of a handful of things we do. These are the ones this account leant on, written up in full rather than summarised.
- How we scope and build custom softwareDiscovery, build, handover and what the code and hosting arrangement look like when it is finished.
- The front end this platform sits behindAn internal tool still needs a public site that explains it. This is the design and build side of the same engagement.
- The technology division that delivered itEnterprise and government software builds, hosting arrangements, escrow and the support model behind a project of this size.
The briefing behind the work.
The case study records what happened. These two explain the channel, measurement or operating decision that made the result interpretable in the first place.
The ownership, governance and operating constraints behind an internal data product. That case is argued in Why first-party data projects stall outside tier one.
A practical accountability question for any workflow that places a model between an operator and an output. The other half of it is set out in When AI drafts the brief, who owns the message?.
The work behind this one is written up in full under how we scope and build custom software, and the operating sequence behind every study on this site sets out the sequence in order.
Want results like this?
Thirty minutes on your numbers rather than somebody else's, and a written list of what we would change first. Yours to keep either way.
No pitch deck. No upsell. A real conversation and a written list of leaks.
