How Viridian Glass prevents bad debt and gets paid on time with CONQA
In construction, proof equals payment. With evidence supported claims, on-time payment rates have climbed from around 50-60% to 80%, and overall bad debt has been reduced by an estimated 30-40%

What happens when great work isn't enough to get paid?
Viridian Glass is one of New Zealand's leading commercial glazing companies, trusted on complex builds from multi-storey apartments to hotels and high-performance fit-outs. They know they have skilled teams who can do the job right, but on fast-paced, chaotic sites, that wasn’t always enough. Without a consistent way to prove when and how work was completed, getting paid in full and on time became harder than it should have been.
Before rolling out CONQA, Viridian’s QA process was inconsistent. Different sites might run things differently, and physical paperwork was often submitted late or incomplete. A “tick-box culture” meant the documentation might look fine, but the work itself hadn’t been properly checked. When issues were spotted, often caused by cleaners, subcontractors, or follow-on trades, Viridian didn't have the indisputable proof that their work had been delivered free of defects.
"We’d do a million, 1.5 million dollars worth of window glazing on a high-rise apartment, and then the cleaners would come in and go nuts with their razorblades... Or you’d have pit marks from guys with grinders... That’s what leads to the arguments later on, and that’s ultimately what holds up your payments."
The consequences were significant. Blair puts it plainly: in today's landscape, if you don't have the evidence, you risk not getting paid. This stretches cash flow, wastes hours in dispute resolution, and could damage relationships with key clients.
"More and more frequently… if we don't provide QA, we're not getting paid that following month."

A simple way to prove work and secure payment
Viridian implemented CONQA as the solution for its installation teams. The platform allows them to capture photo evidence of completed work in real time, directly from the job site. QA Reports are then generated and attached to progress claims, giving clients visibility and removing any uncertainty.
"Once we QA it and send it to the construction company or the fabricator, it's their responsibility, and we get paid for it."
Blair notes that the change has been cultural as well as operational. Teams know what is expected of them, and their work is being documented clearly. Everyone is on the same page about what was done, when, and to what standard.
“The big one for us is quality workmanship from our guys, and evidence that it's been put in, completed, and enabling us to get paid.”

What has changed since using CONQA?
Unblocking cash flow
By including CONQA's QA Reports alongside their claims, Viridian Glass has transformed their ability to get paid on time.
Clients and main contractors now have the assurance they need to process invoices quickly, dramatically improving Viridian's cash flow. The numbers speak for themselves: on-time payment rates have climbed from around 50-60% to 80%, and overall bad debt has been reduced by an estimated 30-40%.
Ending the cycle of blame and disputes
One of Viridian’s biggest challenges was being blamed for damage caused by other trades after their installation was complete. Without a clear record of handover, it was their word against someone else's.
CONQA solves this by creating an indisputable, timestamped visual record of every defect-free installation. This evidence now protects Viridian from unfair back-charges and ensures accountability is placed where it belongs. The focus has shifted from arguing about past problems to preventing them from happening in the first place.
With CONQA, 80% of Viridian’s payment claims are paid on time, up from as low as 50%
Proof, payment, and peace of mind
For Viridian Glass, CONQA is more than just a QA tool, it’s a core part of their financial and operational strategy. By replacing complex disputes with the simplicity of indisputable proof, Viridian now operates with more confidence, control, and a healthier bottom line, where every job is backed by proof, and every payment is protected by process.
