Strategy and the purpose of custom software

Why core processes can’t be bought off the shelf and how partnership delivery drives outcomes.

Key question

Can a ready-made system replace the key production process?

Why you can’t buy the business core

Standard processes can be automated with off-the-shelf tools, but the core workflow is unique and evolves with the business.

What belongs to the core

  • request intake and routing between teams
  • stage and timeline management
  • quality control and materials accounting
  • integrations with accounting and external systems

Why a box solution fails

  • the process is unique and doesn’t fit templates
  • logic changes as the business grows
  • the core defines competitive advantage

When custom is justified

  • errors and delays are expensive
  • real roles and regulations matter
  • the system must follow the business, not the other way around

Key idea

If the process defines your advantage, it must be built, not bought.

Key question

What’s the difference between contract delivery and a partnership model?

Developer as a partner, not a contractor

In complex systems, requirements evolve. You need a partner who owns the outcome, not just the spec.

Contractor

  • follows the document without rethinking
  • treats changes as extra work
  • responsibility ends with execution

Partner

  • focuses on the business goal
  • warns about risks and proposes alternatives
  • shares responsibility for decisions

Business impact

  • less rework and technical debt
  • faster growth after launch
  • fewer strategic mistakes

Key idea

In complex projects, the real value is outcome ownership.

Key question

How do you evaluate impact and justify the spend?

Economic viability of custom software

Software is an investment in process change; the economic effect is defined by how the business operates after rollout.

Where the effect comes from

  • process optimization and lower operating costs
  • higher throughput without proportional headcount
  • lower cost of errors and losses
  • faster cash cycle
  • better governance and transparency

What to count as investment

  • MVP and follow-up development
  • implementation and process adaptation
  • team enablement and training
  • support and ongoing development

How to estimate ROI

  • time saved × hourly cost
  • error reduction × average error cost
  • avoided hiring
  • faster cash inflow

Payback and expectations

  • effect appears gradually
  • MVP already delivers some value
  • payback is often 12–18 months

How to confirm impact

  • capture baseline metrics before launch
  • define key effectiveness KPIs
  • compare before/after dynamics

Key idea

Economics are defined by operational change, not by the amount of code.

Portals and user workflows

How portals create value for clients and employees, and how to drive adoption.

Key question

Why does a client need a portal if there is a manager?

The value of a B2B client portal

A portal provides 24/7 self-service, transparency, and speed. It removes routine from managers and scales service.

What the client gets

  • 24/7 self-service
  • single source of truth for orders and docs
  • faster actions without waiting
  • personalized terms and roles
  • fewer errors and manual input

What the business gets

  • less manual operations
  • scaling without staff growth
  • managers focus on growth, not routine

Key idea

In B2B, service equals speed, transparency, and control.

Key question

Why do clients keep emailing and texting instead?

Why portals fail to take off (and how to avoid it)

The issue is usually that the portal complicates the familiar flow and gives no immediate benefit.

Reasons for resistance

  • clients already have their own working context
  • phone and messenger are faster
  • no instant payoff for switching

The main mistake

  • forcing adoption with “portal only” rules
  • optimizing for internal convenience, not the client

How to reduce friction

  • make the portal a continuation of familiar actions
  • start with statuses and documents
  • be faster than the manager
  • minimum required fields
  • mobile-first and asynchronous flow

Key idea

People resist extra work, not digitalization.

Key question

When do field and remote teams need a portal?

Remote employee portal

A digital workplace that captures facts, controls timelines, and supports scale.

When it is needed

  • employees work outside the office
  • facts must be recorded, not agreements
  • you need control of time, quality, and resources
  • the company is scaling

When it can wait

  • very small teams
  • low cost of errors
  • unstable informal processes

MVP features

  • auth and task list
  • start/finish tracking
  • checklists, reports, photos/videos
  • status updates

Expansion

  • geolocation and materials accounting
  • offline mode and push notifications
  • work history and approvals
  • dashboards for managers

Key idea

A portal turns “trust-based” work into a manageable process.

Integrations and data exchange

How to choose the right automation level and launch integrations rationally.

Key question

What signals that integration will pay off?

When integrations are truly needed

Integrations pay off when exchange is frequent, errors are costly, and data volume is high.

Integration effects

  • faster data updates
  • higher accuracy and less manual input
  • scalability without headcount growth
  • transparent statuses and documents

Key criteria

  • high exchange frequency
  • errors are expensive
  • large data volume
  • speed is critical for service
  • integration creates advantage

Key idea

Integration is an investment in speed and scale.

Key question

When does integration become a costly burden?

When integrations should be delayed

If exchange is rare, processes are unstable, or the other side isn’t ready — start simple.

Signals it’s too early

  • infrequent or irregular exchange
  • processes are not stable yet
  • no API or accountable IT owner
  • fast MVP launch is required

What to use instead

  • email for legally significant documents
  • messengers for quick approvals
  • shared folders for regular file exchange

Key idea

Stabilize the process first, then automate.

Key question

Where to start so integration doesn’t become endless building?

How to launch integrations correctly

Agree on data and master systems first, then automate what already works manually.

Step 1: align on data

  • which entities are exchanged
  • responsibility ownership
  • format and structure

Step 2: define master systems

  • where the current prices live
  • where order statuses and docs live
  • which system is truth for payments

Step 3: start simple

  • CSV/Excel exchange
  • shared folder
  • clear schedule

Step 4: automate

  • API
  • webhooks
  • queues
  • monitoring

Key idea

Automate only what already works reliably by hand.

Specs, requirements, and expectation management

How to write requirements for complex B2B systems so they guide rather than block delivery.

Key question

Why can’t we define everything upfront?

A rational spec: a frame, not a script

In complex B2B systems, parts of logic emerge during delivery. The spec should set direction and fix criticals.

Why not everything is formalized

  • hidden rules that surface later
  • integration constraints appear in practice
  • engineering choices affect cost

What must be fixed

  • system goals and core processes
  • roles and responsibilities
  • critical constraints and integrations

How to keep control

  • fix a baseline scope
  • discuss changes in advance
  • agree on impact to time and budget

Key idea

Project value comes from a working solution, not from matching the first document.
