Services
Who it serves
Overview
Simplex Group describes itself as a back office for trucking companies. It handles compliance, authority, permits, taxes and ELDs, and works alongside two sister companies: Simplex Insurance for commercial truck insurance and Freight 4 U for freight planning and factoring. The company has four offices, in Miami, Florida; Rancho Cucamonga, California; Houston, Texas; and Richardson, Texas, and says it has served more than 10,000 trucking companies over more than 25 years.
Simplex's compliance pages are unusually direct about the limits of outsourcing. One page states that outsourcing moves the work but not the legal duty, and lists responsibilities that stay with the carrier no matter who it hires. That makes it a useful reference even for carriers comparing several providers.
Compare with other Compliance providers: National Drug Screening, Trucksafe Consulting and J. J. Keller & Associates, or see all Compliance.
Services
DOT and FMCSA compliance: setting up and maintaining safety programs, driver qualification files, drug and alcohol testing, hours of service records, CSA monitoring and DOT mock audits. Simplex says it helps organize records, explains what an auditor will request and stays with the carrier through the audit.
Authority packages: USDOT and MC numbers, BOC-3 filing and UCR, plus intrastate authority packages for carriers that operate within one state.
Permits: oversize and overweight permits, temporary IFTA and IRP trip permits, and local permits such as PortMiami cartage permits.
Taxes and filings: IFTA reports, Form 2290 and UCR.
Other: ELD services, tag services, and through sister companies, insurance and factoring.
Who it is for
Simplex is a fit for owner-operators and small to mid-size carriers that want one office to handle authority, permits, fuel tax and compliance paperwork, especially carriers near its offices in South Florida, Southern California and Texas. Its three program tiers let a carrier choose between doing much of the work itself and handing it off to a dedicated account manager.
Because the group also offers insurance, factoring and ELDs, a new carrier can set up most of its back office through one company. Carriers that prefer to keep insurance or factoring with other providers can still buy the compliance and permit services on their own.
How working with them works
Simplex offers three compliance program levels: Simplex Hub, a self-service option; Essentials, with on-demand support from its team; and Managed, with a dedicated account manager. The company says carriers keep visibility into every file and account. Engagements start with a free consultation or quote request. Simplex's own service prices are not published on the pages reviewed.
Its compliance page does list some outside costs: biennial registration updates with FMCSA are free, FMCSA forms are free to download, Clearinghouse queries cost $1.25 each, and Form 2290 is an IRS tax with a separate fee charged by the e-file provider.
Questions to ask before you sign
Which tasks will Simplex do and which stay with you? Simplex's own page lists duties that remain with the carrier: keeping company data accurate and controlling your own FMCSA account, deciding who is qualified to drive and keeping a file for each driver, making designated employer representative decisions and reasonable-suspicion and post-accident testing decisions, requiring drivers to follow hours of service rules, producing records for an auditor, and designating your C/TPA in the Clearinghouse yourself rather than sharing logins. Ask Simplex to confirm each one in writing.
What can you file yourself for free? The MCS-150 biennial update is free with FMCSA, and FMCSA forms are free to download. Ask what Simplex charges for preparing and submitting each filing, separate from government fees.
Which program tier fits you, and what is the monthly or per-service price for each?
What audit support is included? Ask whether the mock audit and in-audit help are included in Essentials or Managed, or billed separately.
If you also buy insurance or factoring from the sister companies, are any services bundled or conditional? Simplex Group is a private company, not a government agency, and FMCSA does not endorse private vendors.
