How BW Interiors Is Putting Its Supply Chain First

Reading time · 3 minPublished · 4 June 2026

There is a quiet problem at the heart of construction. The people doing the work are usually the last to get paid. Subcontractors carry the cost of labour and materials for weeks, sometimes months, while they wait for an invoice to clear. To bridge the gap, many turn to factoring or invoice finance, which is expensive and, once you start, surprisingly hard to stop.

BW Interiors decided to do something about it.

BW is one of London's most respected fit-out contractors, the kind of firm that builds the workplaces other companies aspire to occupy. Reputations like that are not built on design alone. They are built on how you treat the businesses that show up on site every day to deliver the work. And BW wanted to treat its supply chain better.

So they partnered with Copay.

A simple idea with a real effect

Here is what changed. Through Copay, BW now offers its subcontractors the option to be paid early. A supplier who would normally wait for the agreed payment date can choose to get their money sooner, in exchange for a small discount they decide is worth it. Nobody is forced to take it. The ones who value certainty and cash flow opt in. The ones who would rather wait simply carry on as before. What makes this work is that BW pays its own supply chain directly. There is no outside lender stepping in, no third party taking on the debt, no hidden financing arrangement layered on top. Copay is the technology that makes the whole thing run, calculating the discount, generating the paperwork, and adjusting the payment dates automatically inside BW's existing systems. The contractor stays in control. The subcontractor gets a genuine choice. And the cash moves faster across the board.

It is the kind of solution that sounds obvious once you see it, which is usually the sign of a good one.

What it actually felt like

The fear with any new platform is the rollout. Finance teams have lived through enough "transformations" to be wary of the word. BW's experience was the opposite.

Theo Riakiotakis, FD, BW Interiors: 10/10 experience since partnering with Copay. The platform was quick to implement and effortless to go live with, supported by a team that made the whole process refreshingly straightforward. The simplicity of the technology makes it easy for everyone to use, while delivering real impact for both us as a contractor and our supply chain partners.

Quick to implement. Effortless to go live. Easy for everyone to use. That is not the language people usually reach for when they describe new finance software, and it is exactly the bar we set for ourselves.

The part that surprised us most

We expected the contractor to be happy. What stayed with us was what the supply chain said. These are the businesses the whole industry depends on and rarely hears from directly. So we asked them. Here is what they told us.

Cash flow keeping us up at night is no secret. What gets overlooked is the uncertainty around when payment actually lands. BW has always been our best client, so no wonder they are the ones adopting Copay to support us even further. This is what construction should look like.

Why this matters

Construction is the only major industry where the people doing the work routinely finance the people paying them. That has been true for decades, and most of the sector treats it as a fact of life. BW Interiors looked at it and decided it did not have to be. By giving its supply chain the option to accelerate payments, BW is doing more than smoothing cash flow. It is signalling what kind of partner it intends to be. In a market where good subcontractors are in demand and loyalty is earned, that is a genuine advantage. The firms that look after their supply chain today are the ones who will still have a supply chain worth having tomorrow.

That is the future we are building toward at Copay. A construction industry with a shared payment rail, where early payment is the norm rather than a favour, and where doing the right thing by your suppliers also happens to be the smart commercial move.

BW Interiors is already there.
