Subscription model
Plans, periods and lifecycle rules agreed.
Connect recurring payments to the service customers receive. We define trials, renewals, failed payments and cancellation timing, then verify how provider events change the subscription and local access state.

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 paid invoice, active plan and allowed feature are related but separate states. We agree which provider information controls each local decision.
Trial expiry, overdue periods and customer authentication need explicit behaviour rather than a single paid-or-unpaid flag.
Ending at the next renewal differs from immediate cancellation. Plan changes may introduce prorated charges according to provider settings.
We define customer feedback and staff controls. Tax configuration, provider fees and accounting requirements are assessed separately.
Testing follows renewals, failed attempts, repeated notifications and delayed updates. State changes should remain consistent when an event is processed again.
Vladimir Nikolaev reviews acceptance with you. We distinguish cancellation from refunds and agree their effect on service access before release.

Answered by Vladimir Nikolaev.
Yes, if supported by the chosen provider and agreed model.
Possibly, depending on provider support and the agreed expiry rules.
Not automatically. Those operations and access effects need separate rules.
Transaction and subscription-provider charges are separate.

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.

Add the function your website is missing without rebuilding the whole system. We develop extensions with a defined job, manageable settings and checks against your current platform.

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 enquiry.
Include access, cancellation and failure rules. We will map the billing lifecycle.
