Services / Custom development & integrations

Custom development & integrations.

Build a focused feature, internal workflow or system connection around a real business task. Define the inputs, outputs and handoff before expanding the work.

The job this service must do

Custom development should remove a specific operational constraint. Inputs, outputs, system ownership and failure states are visible before code connects business-critical tools.

A useful first scope

What we define
and deliver.

  • A mapped input, output and acceptance check
  • The agreed feature or one or two scoped connections
  • Visible failure handling and handover notes

API permissions, data handling, usage charges and vendor limits need explicit decisions. Larger workflows, complex permissions and production support are scoped separately.

Service coverage

What the work can include.

The final combination follows the project brief. Every included page, feature, integration and review point is named in the written scope before implementation.

01

Workflow mapping

The trigger, data, decisions, exceptions and final handoff documented in plain language.

02

Custom feature development

A focused internal tool, website capability or application feature built around the agreed task.

03

API and system integration

One or two established services connected with explicit authentication and data-handling boundaries.

04

Failure visibility

Retries, logs and operator-facing errors designed so silent failures do not become hidden work.

Working process

From brief to a testable release.

The proposal names the review milestones. Timing depends on the number of pages and features, content readiness and third-party access.

Trace the current task

Document who starts it, what information moves and where manual work or errors occur.

Confirm system access

Review API availability, credentials, rate limits, data policy and vendor costs.

Implement one connection

Build and test the narrowest useful workflow before adding branches or more providers.

Hand over operations

Document monitoring, recovery, access ownership and the person responsible for changes.

Starting price / USD

From $499

Workflow Integration. Final quote after scope.

One focused workflow connecting one or two established systems, with visible failures and a clear handoff point.

API usage, ongoing production support and complex data engineering are additional.

Scope decisions

Questions to settle before build.

The proposal records confirmed requirements and lists any unknowns that need a separate, bounded review.

Source of truth

Each important field needs one authoritative system; conflicting copies create unreliable automation.

Human approval

Financial, customer-facing or irreversible actions may require a clear review step before execution.

Vendor dependency

API changes, usage pricing and account limits remain external constraints and require fallback decisions.

Case study references

Reference studies
and interface details.

Each study identifies its public source, material status and the interface details being reviewed.

Can you connect our existing tools?

Often, if the systems provide suitable access and the required data is clear. We review the connection, ownership and failure cases before committing to the work.

Frequently asked questions

Before you send the brief.

Can you add AI to an existing workflow?

Only when the task, evidence, acceptable error rate and review path are clear. AI is not a substitute for a defined source of truth.

Can you connect any two systems?

No. The systems need suitable access and compatible data. Permissions, vendor restrictions and missing APIs can block the work.

Who monitors the integration after launch?

That responsibility is agreed before launch. Ongoing monitoring and production support are separate unless included in the proposal.
