When Do Custom Software and Digital Platforms Pay Off?
When custom software or your own shop beats licenses and marketplace fees.
In brief
Custom software pays off when avoided license, commission, and process costs exceed development and ongoing operations. These calculators reveal that tipping point with your own figures.
Weigh the investment against follow-on costs
This category groups three comparisons. Which pair you calculate depends on the cost that grows with users or revenue today. The cards below each open one calculator with its own table.
The calculators model recurring fees, internal labor, and growth over the same horizon. That supports make-or-buy decisions. Groenewold IT Solutions has delivered software Made in Germany from Leer, East Frisia, since 2010.

Compare total cost of ownership, not a one-time price
A fair comparison includes every payment over the intended useful life. Standard software costs include user licenses, annual price increases, paid modules, implementation, and integrations. Custom software costs include discovery, development, quality assurance, hosting, maintenance, and planned enhancements. The calculator places these items on the same timeline. This reveals whether a low entry price becomes expensive over time or whether a larger initial investment is offset by lower variable costs.
Scale changes the picture. Commission grows with revenue. Fixed operations and care for an owned system usually do not grow at the same rate. Count only hours that actually disappear. Run a cautious, an expected, and an ambitious case with the same inputs.
- Capture project, implementation, migration, and onboarding costs in full
- Project licenses, commission, hosting, maintenance, and support by year
- Value only hours that can genuinely be removed or used productively
- Document strategic control, reduced dependency, and residual value separately
Build an investment case decision-makers can trust
A positive calculator result is not yet an investment approval. Business teams, IT, and management should validate the same assumptions before work begins. Relevant inputs include user growth, process volume, delivery duration, adoption, and implementation effort. Sensitivity analysis identifies the variable with the greatest influence. If break-even depends on perfect adoption, the initiative needs a stronger rollout and change plan. If value remains positive under cautious assumptions, the case is considerably more resilient.
After launch, calculator inputs should become operating metrics. License invoices, order volume, handling time, portal usage, and support demand can be measured against the baseline. ROI then becomes a management tool rather than a one-time forecast. Phased delivery also limits exposure: a focused MVP tests the most valuable assumption before more features are funded. The architecture and data model should still support the intended scale, avoiding a cheap prototype that must be rebuilt after validation.
Frequently asked questions
About Software Development & Platforms
Break-even & usage
Which of the three pairs should I calculate first?
If cost grows with user count, start with custom software against licences.
If it grows with revenue, start with an owned shop against marketplace commission. If the effort is search, dispatch, and enquiries, start with the document portal. Each card links to the matching calculator and its table.
Why do the cards show different months?
Each card shows that calculator’s lead range, not a shared average.
Mid-size teams sit at 24 to 36 months for custom software, high shop revenue at 12 to 18 months, and document portals often at 8 to 22 months. The tables on the calculator pages split further by size.
How should time savings be valued?
Use observed volumes and measured handling times.
Value only the share that actually disappears, frees capacity, or supports extra throughput.
Can the calculator be used before a discovery workshop?
Yes.
The calculator shows which assumption moves the month the most. A discovery workshop checks processes, risks, and technical limits. The same table can then be rerun with a tighter effort estimate.
