Seattle carries software, professional services, healthcare, manufacturing, aerospace suppliers and home services; Spokane carries healthcare, manufacturing and the trades, and Tacoma adds port logistics. Washington has no personal or corporate income tax but levies a business and occupation tax on gross receipts, with rates by activity, and a capital gains tax that can reach the sale of a business. Contractors register with the Department of Labor and Industries with bonding and insurance, and electricians and plumbers hold state licenses. Non-compete agreements are limited by state law. SBA 7(a) lending is active, with the SBA district office in Seattle. Seattle, Spokane and Tacoma are the active metros.

What to Look For
Practical guidance from hundreds of real acquisition conversations.
Recurring vs. Project Revenue
- Ask for a revenue breakdown separating monitoring contracts, managed security service agreements, annual software subscriptions, and maintenance agreements from one-time installation and project work.
- The contracted, repeating income is what drives premium valuations — project work matters too, but it has to be re-won each cycle.
- Monitoring contracts and managed service agreements that renew without re-selling are the single most important revenue quality signal across all security sub-categories.
Credentials and Clearances
- Understanding exactly who holds which credentials and whether those people plan to stay is one of the most important due diligence questions in this category.
- Security clearances, particularly high-level ones, take years to obtain and cannot be quickly rebuilt after a sale.
- Low-voltage licenses, manufacturer certifications, and CISSP or similar credentials are genuine competitive advantages that transfer with the people who hold them.
Contract Depth and Transfer
- Ask to see the contract list with expiration dates, renewal history, and what each agreement says about ownership transfers.
- Long-term contracts — whether multi-year government agreements, commercial service agreements, or monitoring subscriptions with auto-renew — separate a company with stable income from one riding on project volume.
- Government contracts require additional care, since some require formal approval or re-certification when ownership changes.
Equipment and Integration Stickiness
- Ask what percentage of clients have installed equipment and what the renewal rates look like on service and monitoring agreements covering those systems.
- In physical security and security technology, installed equipment creates a loyalty effect buyers can get genuinely excited about — cameras, access control panels, and intrusion systems wired into a building are expensive and disruptive to replace.
- When clients have your hardware in their walls and your software in their workflows, they tend to stay.
Team and Operations Independence
- Ask who handles each major client relationship and what happens to operations if the owner steps away for a month.
- The best security acquisitions run without the owner dispatching every job — whether it's a security operations center staffed around the clock, a dispatcher routing technicians independently, or an operations manager who handles installs and client calls without the founder.
- Management depth is what makes a security business truly transferable.

Security businesses land across a wide range because the difference between a company with a cleared team and multi-year government contracts versus one dependent on one-off installation projects is enormous from a risk and cash flow standpoint.
