Here at Johnstone we are prepared to tackle the nuances of doing business in the Government Sector. We understand the importance of the packet that accompanies all bid requests and orders as well as its accuracy being a required need and can be a disqualifying issue depending on the agency. JSOG is very aware of which category we are most prominent in and can share it across many different agencies. Proper positioning in the market with regards to the Darfur Accord and any and all dealings outside of US borders is crucial. Be aware that certain vendors may disqualify themselves by having dealings against the Accord or its related policies. Many agencies have longer than normal lead to pay options and are never simply a NET-30 Client. Often, all agencies are tasked to work with the lowest bidder, no matter the class or size of the project. The author of the bid must be mindful of effective margins and add-ins affecting final cost to client agency. All agency bid requests come with a due date that is very rarely extended. The date and time is specific and we are mindful of vendor management with regards to these deadlines. Freight costs and special handling fees are always built into the cost of the items being bid unless an exception is made by the requesting party. We are aware of our due diligence and are prepared to work closely with all agencies for all of their HVAC/R & IAQ needs. To have a conversation about our willingness to serve, please contact Ken Gibbs @ 559-421-1226.
