How we make delivery reviewable

Fewer promises. Clearer responsibilities.

Before delivery begins, we agree what is included, how it will be accepted, and what remains under your ownership.

Written scope and assumptions

Goals, included capabilities, dependencies, acceptance criteria, and exclusions remain visible throughout delivery.

Your repository and accounts

Code, production accounts, data, access, and intellectual-property ownership are addressed in the agreement and handover.

Staged delivery and review points

The project is divided into working outcomes you can review before the next scope or investment decision.

QA, launch, and handover

Testing, deployment, documentation, and knowledge transfer are included when they form part of the agreed scope.

Decision guides

Plan your project with practical guides

Set a realistic budget, identify when a shared system is justified, and test the investment case before a technical commitment.

Custom Software Development FAQ

Direct answers for planning investment, scope, and the next step.

What does custom software development cost?

Discovery or prototype work commonly costs €2,500–€7,500, a focused production build €15,000–€40,000, and an integrated multi-role platform €40,000–€120,000+. Roles, workflows, integrations, data, security, and acceptance criteria determine the final estimate.

How much does it cost to build an MVP?

A prototype used to validate the workflow commonly costs €2,500–€7,500. A focused production MVP usually starts around €15,000–€40,000, while multiple roles, payments, integrations, or regulated data can move the project above that range.

Read the MVP development cost guide
How much does it cost to build a mobile app?

A clickable or technical prototype commonly costs €3,000–€8,000. A focused iOS and Android product typically costs €12,000–€35,000, while payments, complex backend workflows, offline data, hardware, or several roles can move the build above €35,000.

Read the mobile app cost guide
When should a company replace spreadsheets with custom software?

Consider a shared system when one spreadsheet controls a critical workflow, several people edit competing copies, permissions and change history matter, or manual copying between tools creates recurring errors. Keep the spreadsheet when the work is temporary, low-risk, and owned by one person.

See when spreadsheets become operational risk
Which processes are good candidates for AI automation?

Start with a frequent, bounded process that has recognizable inputs, a reviewable output, clear exception rules, and a measurable baseline. Document intake, classification, extraction, search, routing, and draft preparation are often better first candidates than open-ended autonomous decision making.

Find the right process for AI automation
How do you calculate AI automation ROI?

Measure the annual value of time saved and avoidable rework, adjust it for realistic adoption and human review, subtract implementation and operating costs, and divide the net benefit by total cost. Use the same period for benefits and costs, and validate assumptions with a bounded pilot.
