In the short term, licensed software almost always appears to be the most economical choice due to lower initial entry costs. However, evaluating enterprise software with a horizon of just a few months is a financial mistake. The real lifecycle of a core B2B tool is at least 5 years. Within this timeframe, the dynamics of **TCO (Total Cost of Ownership)** flip. ### **Comparative Scenario (50-user company)** To quantify the cost difference, let us assume a real operational scenario for an SME or manufacturing company that requires a production and logistics management platform **for 50 operational users.** #### Option A: Licensed Software (B2B SaaS) - **License cost per user**: €40/month (€480/year per user). - **Base license cos**t: €24,000/year. - **Setup and initial customization**: €15,000 (one-time). - **Expected price list increases**: +5% annually (B2B SaaS industry standard average). - **Required additional modules (API/ERP Integrations)**: €3,600/year. #### Option B: Custom Software - **Initial custom development (CapEx**): €65,000 (one-time). - **Ongoing maintenance and hosting (OpEx)**: 15% of development value = €9,750/year (starting from year two). - **Cost per additional user**: €0. ### 5-Year Cumulative Cost Projection | Year | Licensed Software (SaaS) | Custom Software | Cumulative Difference | | --- | --- | --- | --- | | Year 1 | €42,600 (Setup + Licenses + Modules) | €65,000 (Full development) | Licensed is cheaper | | Year 2 | €71,400 | €74,750 (Development + Maintenance) | Substantial break-even | | Year 3 | €101,640 (Including +5% price increase) | €84,500 | Custom cheaper by €17,140 | | Year 4 | €133,390 | €94,250 | Custom cheaper by €39,140 | | Year 5 | €166,730 | €104,000 | Custom savings of €62,730 | ### **The hidden costs that invalidate the initial SaaS calculation** Beyond pure numbers, the evaluation must include four structural variables that impact indirect operating costs: #### **1. The scalability trap (cost per headcount)** One of the most insidious aspects of adopting licensed software concerns how infrastructure cost reacts to a company’s natural growth. If we take an organization growing from 50 to 80 employees over five years, under a SaaS model, the increase in headcount immediately converts into an exponential expense line: license fees alone end up exceeding €40,000 per year, pushing the total five-year cost past the €220,000 threshold. Conversely, a custom-built solution absorbs workforce expansion without financial penalties. Because the architecture and code belong to the company, development and maintenance expenses remain stable at around €104,000 total over five years, effectively reducing the marginal cost for every new user accessing the platform to zero. #### **2. Process adaptation vs. software adaptation** Beyond direct financial impact, choosing between a standard product and a custom project determines who must adapt to whom within the organization. When adopting rigid licensed software, it is almost always the company that must overhaul its established procedures to yield to the logic imposed by the tool. This reversal of priorities triggers a series of silent yet damaging daily frictions. Employee onboarding times lengthen significantly, while the platform’s inevitable gaps force workers to devise workaround solutions—such as constant reliance on external Excel spreadsheets to cross-reference data the software cannot handle. The result is an accumulation of operational inefficiencies that, while difficult to quantify on a balance sheet, erode actual business productivity day after day. #### **3. Vendor lock-in and pricing risk** SaaS vendors unilaterally change pricing plans and licensing conditions. Once a company has migrated all its processes to a third-party platform, switching costs to another system become so prohibitive that the organization is forced to accept any price increase. #### **4. Integration with existing systems (legacy and ERP)** Commercial software provides standard APIs, but connecting SaaS to a proprietary ERP or shop-floor machinery requires custom connectors. Frequently, the development cost of connectors alone—just to get SaaS talking to the factory—exceeds the cost of the SaaS itself. ### **When to choose licensing vs. custom** There is no single answer; rather, the choice depends on the strategic criticality of the process. ``` PROCESS CRITICALITY Low High ┌─────────────────────┬─────────────────────┐ High │ SaaS SoftwARE │ CUSTOM SOFTWARE │ │ Commercial │ (Competitive │ PROCESS │ (e.g. Generic CRM)│ Advantage) │ COMPLEXITY ├─────────────────────┼─────────────────────┤ Low │ Standard Software │ SaaS / Utility │ │ (e.g. Invoicing) │ Low customiz. │ └─────────────────────┴─────────────────────┘ ``` The choice between an off-the-shelf product and a custom project ultimately boils down to the impact technology has on the core of the business. **Licensed software** is the ideal solution when managing standardized, non-strategic processes: so-called commodities, such as email, basic accounting, or payroll processing. If the organization is small, has fewer than fifteen users, and foresees no immediate headcount expansion—or if there is an urgent need to deploy a tool within forty-eight hours while accepting out-of-the-box features—turning to existing market options is the fastest and most cost-effective path. Perspectives shift radically when technology must support core business operations or production processes that define the company’s competitive differentiator. In this scenario, custom development becomes an almost mandatory strategic choice. When a platform is used daily by more than thirty or forty operators, yielding to the rigidity of commercial software means accepting continuous compromises that ultimately slow down productivity, forcing staff to patch operational gaps with paper forms or a messy web of separate Excel sheets. Investing in a custom solution instead allows the tool to be molded around actual business workflows and ensures full control over the technological asset’s intellectual property, permanently freeing the company from third-party vendor constraints and price hikes. ### **Conclusion** Purchasing licensed software shifts investment from CapEx to OpEx, but beyond three years of use or the 30–40 user threshold, the SaaS model turns into a financial annuity benefiting the vendor at the company’s expense. Custom development requires higher upfront capital, but guarantees **total independence, zero marginal cost on headcount growth, and a positive ROI starting as early as the 36th month**. *Need to evaluate the financial or technical feasibility of a new internal management system?
