Cost Calculators: Software Development & Platforms

Executive answer

Find calculators for new software products: apps, web, shops, SaaS, portals and industry systems. Ranges follow real project patterns – development Made in Germany from East Frisia.

All cost calculators · Overview of all categories and calculators.

Custom software instead of templates

Standard software covers many processes but breaks on special logic, industry rules or deep integration. Custom development pays off when differentiation, scale or compliance are central.

Calculators in this category cover apps, web, shops and industry solutions – from MVP to mature platform. You get ranges for architecture, UI/UX, backend and interfaces.

Groenewold IT Solutions has built B2B software for mid-market clients for more than 15 years. Assumptions reflect typical projects from East Frisia and across Germany.

Apps, web and digital products

Mobile apps differ strongly by platform choice, offline capability and backend complexity. Web development spans marketing sites to SaaS with multi-tenancy and billing.

Online shops range from standard platforms to custom checkout with ERP integration. PWAs and intranet portals are often a faster path to internal value without app-store hurdles.

Industry calculators – from trades to real estate to events – help budget domain-specific modules and workflows realistically.

What drives the price

Cost drivers are number of roles, integration points, design depth, testing effort and operating model. An MVP with three core features is cheaper than a multi-tenant platform with billing.

Data migration, permission models and multilingual support are often underestimated. Plan buffer for acceptance, training and first releases after go-live.

Reference in our models: EUR 140 per hour excl. VAT – clearly communicated, no hidden day rates. Fixed prices follow scope freeze and architecture review.

From idea to launch

Start with the calculator closest to your product type. Add integration and operations calculators from other categories when ERP, AI or legacy are involved.

Results are orientation ranges. Deviation comes from UX complexity, third-party APIs and regulatory requirements – such as GDPR or industry-specific evidence.

Bring calculator outputs to the initial call. We propose a sensible MVP scope and define measurable delivery milestones for the first sprints.

Platforms and scaling

SaaS, white-label and marketplaces need multi-tenancy, monitoring and release processes from day one. Budget not only feature lists but also DevOps and support capacity.

Customer, client or document portals often connect ERP, CRM and identity. Interface effort belongs in the same budget discussion as frontend and backend.

Made in Germany means close alignment, documented architecture and long-term maintainability – not an anonymous nearshore team without domain knowledge.

Next steps for decision makers

Compare several calculators when your initiative combines product types – for example app plus web portal plus shop.

Linked services for app development, software development and online shop creation provide deeper information on approach and technologies.

If the range fits your frame, book a meeting. We turn it into a credible quote with clear scope and transparent risk. The calculators in this category provide credible ranges for mid-market projects and do not replace a tailored quote after an initial consultation.
