Maximizing ABC Supply contractor programs with Nexus GPO
Steven Lord · June 4, 2026

If you’re a roofing contractor doing at least $500k in annual revenue, you probably already buy from ABC Supply. You likely have a preferred branch and a sales rep who knows your name. You might even be enrolled in their manufacturer rewards programs, picking up a few points or a 1% check at the end of the year.
That 1% is a rounding error.
At Nexus GPO, we see the same contractors buying the same materials from the same ABC Supply branches, but they’re walking away with tiered rebates that start at 2% base, move to 3% at $500k, 4% at
Your ABC Supply relationship stays exactly the same
The biggest fear contractors have when they hear "GPO" is that they’ll have to change how they work. You’ve spent years building a relationship with your local ABC Supply rep. You trust them to get the materials to the job site on time.
When you join Nexus GPO, that relationship doesn’t move an inch. You still call the same rep. You still pick up from the same branch. You still use your existing credit line.

We aren't a middleman. We are a procurement partner. We work in the background, connecting your ABC purchase data to our network-negotiated rates. Think of it as an invisible upgrade to your current account. You get the service level of a local contractor with the pricing power of a national conglomerate.
Why 1% isn’t enough for your business
The industry standard for solo contractor rebates is roughly 1%. Some manufacturer programs might bump that up slightly with points or travel rewards, but it rarely hits the bottom line as hard cash.
Here is the math on a

M): $40,000That’s a $30,000 difference. That is a new truck. That is the salary of a project manager. That is pure net margin that you are currently handing back to the manufacturer just because you're buying alone.
.5M" />By pooling your volume with hundreds of other contractors in the Nexus GPO network, we negotiate directly with manufacturers and distributors. We turn your existing material spend into quarterly cash deposits because the suppliers value the collective volume of our entire network more than they value any single contractor’s individual loyalty.
The $5,000 guarantee for roofing contractors
We know contractors are skeptical. You’ve heard "more money back" a thousand times from "marketing consultants" who have never stepped foot on a roof.
We are so confident in our ability to improve your margins at ABC Supply that we offer a $5,000 guarantee. If we can’t find you at least $5,000 in additional rebates through our platform, we will write you a check for the difference.

We can offer this because we see the data. Most contractors are missing out on tiered manufacturer rewards and volume incentives because they don't have the time to track every single invoice. Our platform does that automatically. We find the money you're already entitled to, and then we add the GPO network bonus on top of it.
Automatic tracking means no more paperwork
One of the biggest failures of traditional rebate programs is the "claim" process. If you have to spend ten hours a month tracking invoices and mailing them to a manufacturer, the administrative cost often eats the rebate itself.
Nexus GPO is fully integrated with ABC Supply’s data systems.
- Real-time tracking: Every dollar you spend at ABC is automatically tracked in your Nexus dashboard.
- No claiming required: You don't have to upload receipts or fill out forms.
- Quarterly ACH: Every three months, we deposit your earned rebates directly into your bank account.

You can check your real-time dashboard at any time to see exactly how much cash is headed your way. It’s business-first procurement that respects your time.
Advanced notice on storm season price increases
Buying power isn't just about the rebate check; it's about information. During storm season, supply chains get tight and price increases come fast.
Because Nexus GPO represents a massive block of purchasing volume, we often get advance notice on price increases from manufacturers and distributors like ABC Supply. We pass that information directly to our members.
Having a 7-day or 14-day head start on a price hike allows you to lock in orders at lower rates and adjust your bids before your margins get squeezed. In a high-volume season, this "early warning system" can be worth just as much as the rebate check itself.
How to get started with no cost to join
