The verdict in three sentences
SaaS is a rental: OPEX spend, no asset, vendor dependency, but maximum flexibility. Custom is ownership: CAPEX investment, amortizable balance-sheet asset, autonomy and transferable value. The right choice depends on your horizon, your balance-sheet strategy and the software's strategic value.
Rent or own: the implications
The economic model isn't neutral: it affects cash, balance sheet and independence. 2026 comparison.
| Dimension | SaaS license | Owned software |
|---|---|---|
| Accounting nature | Expense (OPEX) | Fixed asset (CAPEX) |
| Cash flow | Smoothed, monthly | Concentrated up front |
| Balance-sheet asset | No | Yes, amortized 3-5 yrs |
| Dependency | High (vendor, versions) | None (you decide) |
| Data | Hosted by the vendor | Under your control |
| Resale value | None | Valuable (sale, fundraise) |
| Evolutions | Per vendor roadmap | Per your priorities |
Amortization and balance-sheet impact
Owned software goes to assets and amortizes; SaaS stays an expense. 2026 illustration for a 100,000 EUR build amortized over 5 years.
| Year | Custom amortization | Equivalent SaaS expense (30 EUR × 40 users) |
|---|---|---|
| Year 1 | 20,000 EUR | 14,400 EUR |
| Year 2 | 20,000 EUR | 14,400 EUR |
| Year 3 | 20,000 EUR | 14,400 EUR |
| Year 4 | 20,000 EUR | 14,400 EUR |
| Year 5 | 20,000 EUR | 14,400 EUR |
| Residual value yr 5 | Amortized but owned | 0 (no asset) |
Custom enriches the balance sheet and gains value on a sale or fundraise; SaaS leaves no asset at term.

Mini case study
Elodie, CEO of a 60-person B2B SaaS scale-up in Lille preparing a raise, assesses her critical internal tool. In SaaS, 5 years of licenses = 72,000 EUR of pure expense, with no asset to show investors. Owned, a 100,000 EUR build becomes an amortizable asset that strengthens the balance sheet and reassures due diligence on tech mastery. She picks ownership for her core module, valued in the raise, and keeps SaaS for non-strategic support functions.
FAQ
Does SaaS create an asset? No: it's an operating expense (OPEX). You own nothing at contract end, unlike developed and capitalized software.
Can custom software be amortized? Yes, as an intangible asset, typically over 3-5 years, smoothing the accounting impact and improving the balance sheet.
Which model for a raise or sale? Ownership: a mastered, valuable software reassures investors and counts in valuation; SaaS leaves no asset.
Who controls my data in SaaS? The vendor hosts it on its terms; owned, you control hosting, location and sovereignty.
Must I choose all one or all the other? No: own the strategic core, rent the support functions. That's the most common 2026 trade-off.
