Everything you need to know about Nexus GPO. Tap a question to see the answer.
Getting Started
What is Nexus GPO?
Nexus GPO is a group purchasing organization built specifically for roofing contractors. We negotiate rebates with your existing suppliers and distributors on your behalf and deposit the earnings directly to your bank account every quarter. You keep buying from the same suppliers you already use. We handle the negotiation, tracking, and payments.
Is there a cost to join?
No. Membership is completely free. There are no subscription fees, no monthly charges, and no hidden costs. We are compensated by our distribution partners, not by you. No cost to contractors, ever.
How do I sign up?
Click Get Started on the homepage and create an account. The onboarding process takes approximately 10 minutes. You will provide your business information, connect your supplier accounts, set up your bank account for ACH deposits, and sign the membership agreement electronically.
Who is eligible to join?
Nexus GPO is designed for licensed roofing contractors doing $500,000 or more in annual revenue who purchase materials through approved distribution partners.
Rebates and Earnings
How do rebates work?
We negotiate rates with approved distributors that are significantly higher than what individual contractors can secure on their own. When you purchase materials through an approved supplier, those negotiated rebates are calculated on your total purchases and the majority is passed back to you.
How much can I earn?
Your earnings depend on your annual material spend. A contractor spending $500,000 per year in materials typically earns $9,000 to
When do I get paid?
Rebates are calculated and deposited quarterly. Q1 covers January through March and is paid by April 15. Q2 covers April through June and is paid by July 15. Q3 covers July through September and is paid by October 15. Q4 covers October through December and is paid by January 15.
How are rebates deposited?
Rebates are deposited directly to your registered business bank account via ACH transfer. There are no checks, no portals to log into, and no minimum threshold to receive payment.
Do I have to switch suppliers to earn rebates?
No. Keep using the suppliers you already trust. We work with the major roofing material distributors. No switching, no new reps, no disruption to your operation.
What purchases qualify for rebates?
Qualifying purchases are material purchases made through approved distributors on your connected supplier accounts. This includes shingles, underlayment, ridge cap, starter strip, flashing, ventilation, and roofing accessories.
How Your Rebate Rate Works
How is my rebate rate determined?
Every Nexus GPO member earns the same network-wide rebate rate on qualifying purchases. We negotiate a gross supplier rebate with each distributor, keep a small administrative spread to operate the program, and pass the rest back to you.
Does my rebate rate go up as the network spends more?
Yes — for the whole network at once. When the combined cumulative material spend across all Nexus GPO members reaches $500,000 in total qualifying purchases (a one-time lifetime milestone), the negotiated supplier rebate permanently steps up and every member's rebate rate increases to 1.75% at the same time.
Can my rate change unexpectedly?
No. Rate changes are network-wide, transparent, and only move in your favor as the GPO grows. There are no individual tiers, no quarterly downgrades, and no surprise rate cuts.
Supplier Connections
How does Nexus GPO track my purchases?
With your authorization during onboarding we connect to your supplier accounts via their secure API. Your purchase data is pulled automatically on a daily basis. You do not need to submit invoices or enter any data manually.
Is my supplier account information secure?
Yes. Your supplier account credentials and banking information are encrypted using AES-256 encryption and stored securely. We never share your credentials with third parties.
Can I connect multiple supplier accounts?
Yes. You can connect accounts from multiple approved distributors. Each connected account's qualifying purchases contribute to your total rebate calculation.
Payments and Banking
How do I set up my bank account for deposits?
During onboarding Step 4 you will provide your business bank account information including account type, bank name, routing number, and account number. You will authorize Nexus GPO to deposit rebate payments to that account via ACH.
What if I need to update my bank account?
Contact your Nexus GPO representative or log in to your account and request a banking update. Your current account remains active until you complete the resubmission.
What if I do not receive my payment?
If your quarterly deposit does not arrive within five business days of the scheduled payment date, contact us at support@nexusgpo.com. Provide your member ID and the quarter in question and we will investigate immediately.
Account and Membership
How do I update my business information?
Log in to your Nexus GPO account and navigate to the Account page. For changes to legal business name, EIN, or license number contact your representative as these may require verification.
Can I cancel my membership?
Yes. You may cancel your membership at any time with 30 days written notice. Any rebates earned through your last active day will be paid on the next scheduled quarterly payout date.
Is my data shared with other contractors?
No. Your purchase data, earnings, and business information are never shared with other Nexus GPO members.
