Why partner with a DVBE-certified company?

why-partner

Every year, Federal and State agencies have to set aside 3% of their contract awards to DVBE. When you partner with a DVBE-certified company, you can go after Federal and State contract gains.

Since 2007, DVBEs are getting top priority, competitive set-asides, better sub-contracting programs, and sole sourcing up to $5 million per contract. You, too, can enjoy these benefits when you partner with a DVBE like Amstar Construction Services.

DVBE groups enjoy a one-of-a-kind bid advantage of up to 10%. California law provides 5% bid advantage to SMBs and 1-5% stackable to DVBEs. This means more success for you in highly competitive and productive biddings.

California law requires the state to help DVBEs increase their contract by sending them notifications about state contract opportunities. By partnering with a DVBE, you can enjoy this marketing and promotion for free.

Partnering with a DVBE ensures prompt payment as stipulated in California’s Prompt Payment Act legislation.
