How we work
Five steps from the first call to the care plan. Scope, cost and schedule always go in the written estimate and the contract.
You can start small. We work through the requirements with you, then send a screen flow or prototype and a written estimate. You decide whether to continue. Scope, cost and schedule are all in that estimate.
We work out the requirements and screen flow with you first. You see the results and a written estimate, then decide on the next step.
The scope and acceptance criteria go in the contract, and you review the work at each milestone. When and how you pay is agreed with you to suit your situation.
Our engineer works on your project for an agreed period. We set the time commitment together and put it in the contract.
We keep running and improving the product after launch. Support scope and response times are agreed with you in the maintenance contract.

Full process, terms and FAQ#faq-3We scope it with you first, then send a written estimate. You can also start with a small first step. How long it takes depends on the size and complexity of what you're building, so we set the schedule per project and put it in the written estimate.
