BEFORE WE BEGIN
About pricing.A few useful answers.
What is included?
Discovery, agreed design and development, testing and handoff documentation. Pages, features, revision rounds, acceptance and payment milestones are specified in the proposal.
Are saved reference prices added together?
No. Your reference basket helps explain style and feature preferences. We prepare one scope and quote for your actual project.
Can we build in phases?
We can define a usable core first and assess the next phase later. Each phase needs agreed scope, fees and dependencies.
How is ongoing maintenance priced?
Maintenance is quoted separately based on update frequency, integrations, hosting and support scope. No unagreed recurring plan is assumed.
