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.
A ready-made extension may already cover the requirement. We review its behavior, licensing and compatibility before proposing custom development. A bespoke plugin makes sense when your workflow or data rules need more control.
Useful examples include a specialized inquiry form, a product pricing rule or a connection to an internal system. The specification describes the action, its inputs and the result your team expects.
Changing a platform's core files makes later updates harder. Where the platform supports extension points, we use them and keep the new function in a separate package.
Administrator settings need validation and sensible defaults. External credentials stay on the server, while permissions determine who can change settings or run sensitive actions.
We check the agreed platform version and the extensions that share its workflow. A checkout feature, for example, needs tests with the actual payment, shipping and caching configuration.
Vladimir Nikolaev agrees the release and rollback procedure with you. Future compatibility updates are maintenance work, so the handover records the tested versions and any known dependencies.

Answered by Vladimir Nikolaev.
Yes, if its licence and source access allow it. We first assess whether an extension or replacement will be easier to maintain.
We normally use supported extension points. Any unavoidable limitation is discussed before the approach is agreed.
No permanent compatibility promise is possible. Delivery records the versions tested; later platform changes may require maintenance.
Yes, for the settings included in the specification. We distinguish editable business values from changes that need development.

Give your team one place to manage requests, records and approvals. We build browser applications around the work people actually do, with clear access rights and a practical first release.

Help buyers estimate a service or configure a product before they contact you. We turn your pricing rules into a clear calculation, with useful explanations and a route to a qualified inquiry.

Connect your website, CRM and operational tools without leaving staff to copy records by hand. We define what moves, which system owns it and how a failed transfer is recovered.
Send your platform version, the relevant plugins and an example of the required behavior. We will assess the simplest maintainable option.
