Clear access boundaries
Agree who can view or change each type of information and how service credentials are managed.
Tested delivery and instructions
Check the agreed scenarios and explain configuration, everyday use and the recovery steps in scope.
Let’s agree what you actually needWe’ll shape the scope around your priorities.

PAYMENT BY PROJECT MILESTONES
Approve a result. Pay for the next milestone.
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.
Your first prototype, before payment
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.
- 0130%
After prototype approval
You approve the prototype or work plan and pay 30% of the agreed project price. We then begin implementation.
- 0230%
After the working version
We demonstrate the agreed main pages and functions, or the named project deliverables. Once you accept this milestone, the next 30% is due.
- 0340%
After project acceptance
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.
HOW WE WORK
Choose the smallest change that solves the problem
Scope, selection criteria and practical delivery details.
You may need a custom application, but sometimes a plugin or an integration is enough. A quote calculator can live inside the existing site. A lead form can connect to the CRM. A reporting task may need a scheduled import rather than a new dashboard.
We examine the current workflow and identify the part that needs development. The initial scope should be small enough to describe clearly and complete enough for the team to use. Additional roles and modules can then follow a deliberate plan.
Agree which system owns the data
When two systems exchange contacts, products or orders, both must recognise the same record. We agree identifiers, field mapping and which system may change each value. This avoids a synchronization job overwriting information another team maintains.
Repeated events, missing fields and temporary API failures need explicit handling. Depending on the task, the solution may include duplicate checks, retries, logging or manual review. The appropriate behaviour is agreed for your workflow rather than added blindly to every integration.
Test the result against the job
Acceptance examples make a brief concrete. For an inquiry integration, a successful form should create the intended record with the right fields. A failed request should have a visible outcome and an agreed way to recover it.
Access, credentials, deployment and rollback responsibilities also belong in the delivery scope. We can start with a review of an existing codebase or implement a defined feature. The estimate names the dependencies and third-party services needed for that work.

Questions before we start
Questions before we start
Answered by Vladimir Nikolaev.
Can you build a single small feature?
Yes. A form repair, calculator, import or API connection can be a standalone project. We first define its inputs, expected result and dependencies so that the estimate is meaningful.
Can you work on existing code?
Yes, after reviewing the code, platform and access. If the current implementation has constraints, we identify them before promising a change or estimating the work.
How do you estimate an integration?
We need the systems involved, supported API access, fields, direction of data flow and failure rules. A sample payload or test account can make the estimate more reliable.
What happens when an external API is unavailable?
The behaviour depends on the agreed scope. We can plan a visible error, retry queue or manual review. Recovery requirements should be discussed before implementation.

Show us the step your team repeats by hand
Describe the current workflow, the systems involved and the result you need. We will identify a practical first feature and the information required to estimate it.
