We define the scope and prepare the agreed first prototype or work plan before payment.
You approve the prototype and pay 30%. We begin the agreed implementation.
We show the main pages and functions or agreed milestone deliverables. After acceptance, you pay the next 30%.
We finish the agreed checks and hand over the project, materials and access. You pay the remaining 40% after acceptance.
Scope agreed before work begins. All prices in USD. Applicable taxes and third-party fees are confirmed in the proposal.
We agree the scope and prepare the first prototype before the first payment. You can review the proposed structure and customer journey before deciding to proceed.
The agreed initial prototype covers the key page or customer journey. For SEO, advertising and other projects without an interface, the first reviewable result is a proposed work plan. The number of screens and revisions is agreed in the brief.
You approve the prototype or work plan and pay 30% of the agreed project price. We then begin implementation.
We demonstrate the agreed main pages and functions, or the named project deliverables. Once you accept this milestone, the next 30% is due.
We complete the agreed checks, deliver the project and hand over the agreed materials and access. The remaining 40% is paid after acceptance.
This schedule applies to projects with a fixed scope. Monthly work and small hourly tasks have separately agreed terms. Advertising spend, hosting, licences and third-party fees are listed separately in the proposal.
We deliver remotely. Briefing, reviews and handover take place online, with the meeting times and working language agreed in advance.
Scope, selection criteria and practical delivery details.
Colour, size, material and accessories may have dependencies. We define which choices are required, optional or incompatible.
Reference configurations establish valid results and explain how missing choices should be handled.
An added option may change a unit price, quantity or quotation requirement. We agree the calculation basis and rounding.
Availability and lead times are included only when backed by the agreed source. A visual preview does not prove manufacturability.
The server checks the selected options before creating a quote or basket item. Stored configuration details should reach the responsible staff.
