Bizee vs. Doola for Engineering Firms: The PE License Problem

Many states require engineering firms to organize as a professional engineering corporation, a PLLC, or a similarly designated professional entity, often with a requirement that a defined share of ownership, sometimes all of it, be held by licensed professional engineers. Some states also require the firm itself to hold a separate certificate of authorization from the licensing board, on top of each individual engineer's personal license. Confirm the exact structure with your state board of professional engineers before filing. This confirmation step takes one phone call and prevents a costly refiling months into practice.

When a PE stamps a drawing, that individual is personally attesting to its accuracy under their license, and that professional liability generally survives regardless of how the firm is structured. The entity limits general business liability, contract disputes, an unpaid vendor, a slip-and-fall at the office, but it doesn't shield an individual engineer from a licensing board complaint or a malpractice claim tied to their own stamped work. Many firms carry both entity-level liability coverage and confirm each PE's individual malpractice coverage separately for this reason.

If you're a solo PE or small partnership operating in one state and you've confirmed the correct professional entity type with your board, Bizee's flat filing fee and first-year included registered agent are a low-cost way to file the underlying paperwork. It doesn't verify board compliance or set up your certificate of authorization, so treat those as separate required steps.

Engineering consulting increasingly draws on remote technical staff, drafters, analysts, junior engineers working toward their own license, based outside the US. If a cofounder or key hire fits that pattern, Doola's EIN filing as a third-party designee skips the Social Security number requirement, and the bundled bookkeeping helps if you'd rather not manage US tax filing alongside project deadlines.

Engineering malpractice insurance, sometimes called professional liability or E&O coverage for engineers, is close to essential given how long a claim can surface after a project completes; many states have a statute of repose that allows construction-related claims for a decade or more after completion, far longer than typical business liability exposure windows. Carriers that specialize in engineering firms understand this extended tail risk better than a generic small-business policy does. Ask any prospective carrier directly how their policy handles claims filed years after a project closes.

State filing fees average $132 nationally¹, a minor cost next to professional liability coverage that needs to account for a decade-plus claims tail. Net margins across the broader market average 8.56%², worth keeping in mind when pricing a fixed-fee engineering study that needs to absorb both project risk and the long-tail insurance cost behind stamped work.

Say a client's contractor makes a field change to a structural detail without routing it back through the engineer of record for review, then a problem surfaces years later during a renovation. If the original stamped drawings and every subsequent revision are clearly documented with who approved what and when, the engineer's liability is bounded by what they actually stamped. Without that trail, an engineer can end up defending work they never actually approved. Keep a clean, dated record of every drawing revision and who signed off on it, whether that approval came from you or was explicitly outside your scope, since that record is often the only thing standing between your firm and an unfair share of blame years after a project wraps.

If you're a domestic, single-state practice that's already confirmed its entity type and certificate of authorization requirements with the board, Bizee gets the underlying filing done cheaply. If you're building a distributed technical team or need EIN help for a founder outside the US, Doola's bundle is worth the extra cost.

Complete these steps before or alongside the entity filing:

• Confirm with your state licensing board which professional entity type is required and what share of ownership licensed engineers must hold.
• Check whether the firm needs its own certificate of authorization, since neither Bizee nor Doola files it for you.
• Document every stamped drawing and revision with who approved what and when, so your liability stays bounded by what you actually stamped.
• Buy professional liability coverage built for a claims tail that can run a decade or more after a project is complete.
• File the entity through Bizee for a single-state practice, or Doola for a distributed technical team or a non-US founder.
