Tell Us A Bit About What You Need...

Your go to guy

Life is made easier with our one point of contact process.  When you work with SFI, you get to know the Regional Manager assigned to your geographical area.  He will take you through your tank project from concept to completion, each and every time.

SFI Sales Department

Not your typical sales team, our Regional Managers are your solution providers.  They have the technical knowledge and decision-making power to keep your project moving from order placement through engineering, production and delivery.

With one point of contact for everything, your time isn’t spent tracking down answers, which allows you to focus on your own work!

Regional Manager Responsibilities

  • Customer’s main contact
  • Reviewing specs, looking for the best solution to customer needs
  • Estimating projects
  • Creating formal proposals
  • Offering alternatives
  • Negotiations
  • Processing orders and change orders
  • Kick-off meetings and coordination between all departments
  • Liaison between the customer and SFI

Supporting the Regional Managers

Your regional manager is your main point of contact but it is unrealistic to think that he will be in the office every workday.  When they are out, we have staff to support them on a day-to-day basis.

  • Project Managers assist the Regional Managers to ensure projects run smoothly and efficiently and provide customer service. 
  • The Sales Department Administrative Assistant types the quotes and orders for the RMs and is available to help should the need arise.
  • Our Office Manager is another resource to provide the necessary information should you have an urgent need. 

Replacement Parts Sales

To allow the RMs to focus on their customers’ tank projects, replacement parts are handled separately by the Replacement Parts Manager, who is responsible for quoting, processing orders and shipping the parts.

As with tank projects, you will have one point of contact for your replacement parts needs.
