We charge a consultation and design fee based on the scope of the project. That fee covers the discovery conversations and the written specification, and you keep the specification regardless of what you decide to do next.
When you move to build, we coordinate sourcing and installation through our vendor and contractor network. Ongoing support is handled through a support agreement sized to your program, which covers operator training, maintenance scheduling, and keeping your consumables and replacement needs planned ahead rather than discovered at the worst moment.
We'll give you the fee structure in the first conversation. There are no percentages we don't tell you about.
