Washington State requires most businesses to obtain a Unified Business Identifier (UBI) through the Business Licensing Service (BLS) of the Department of Revenue. Washington has no state income tax, but does have a Business and Occupation (B&O) tax applied to gross receipts, which is unique among US states.

Frequently Asked Questions

An app development company typically requires a low-to-mid five-figure investment to start, covering business formation, developer accounts, development tools, test devices, and working capital. The largest cost is often skilled developer salaries if hiring beyond the founder.
Simple apps land in the low-to-mid five-figure range; medium-complexity apps in the six-figure range; enterprise or complex custom apps run well into six figures and can reach into seven figures. US hourly rates are typically a healthy three-figure range. Maintenance and updates add a low-to-mid four-figure monthly retainer after launch.
No — app development is highly remote-friendly. Most successful agencies operate distributed teams. A professional home office with a quality video-call setup (a low-to-mid three-figure to low-four-figure outlay) is sufficient. Some agencies maintain coworking memberships for client meetings and team collaboration.
Estimate hours by phase (discovery, design, development, testing, deployment) then multiply by your blended hourly rate — typically a healthy three-figure rate for a US-based team. Always add a meaningful buffer for unknowns. Most agencies use fixed-price contracts with defined scope to reduce client payment disputes.
