you didn’t have to hire.

Your edge is the work you do.

Let’s give you an edge
in how you buy.

The right material at the right price matters. So do the quantities, the freight and the person who answers when something changes. ProMax brings those conversations together.

The whole scope, in view

One project.
A lot less chasing.

Start with what you already have: a takeoff, a supplier quote, a finish schedule. Our desk helps work through the details across the job.

  • Review products and quantities together
  • Put delivery requirements in the picture
  • Keep the decision in your hands

Before you join

Straight answers.

Who is ProMax for?

Contractors, remodelers, builders, designers and property teams buying materials for their work. You can also shop Super Arbor or request a project quote without a trade account.

Does ProMax cost anything?

There is no membership fee to join Super Arbor’s trade program. Account applications are reviewed, and any payment terms require separate approval.

Will I see different prices after signing in?

The catalog’s published prices are visible to everyone. For quantities or a complete project, send your material list for a quote. Project pricing depends on the products, quantities and delivery requirements.

Is sending a material list the same as applying?

No. A material list starts a quote request. To apply for a business account, complete the trade application. You do not need to wait for account approval to request a quote or shop the catalog.

What happens after I apply?

The team reviews the business information you submit. Approval is not automatic. Already approved customers can sign in to the ProMax portal with their account email.

Can I request payment terms or tax-exempt purchasing?

Yes. Discuss payment terms and tax-exempt documentation with the desk. Terms are subject to review and approval; tax-exempt purchases require the appropriate documentation.
