The verdict in three sentences
A custom internal web app in Toronto is budgeted between EUR 18,000 and 90,000 in 2026 depending on business complexity. It pays off as soon as it saves a team more than 15 hours per month, which is the norm for repetitive processes (data entry, reporting, approvals). The real calculation isn't the build cost but the cost of inaction: a company sticking with spreadsheets loses on average the equivalent of a half-time role per year to re-entry and errors.
How much an internal app costs in 2026
The budget depends on the number of screens, integrations (ERP, accounting, third-party APIs) and the level of user permissions. Here are the 2026 ranges for Toronto and its region.
| Internal app type | Scope | 2026 cost (EUR) | Timeline |
|---|---|---|---|
| Simple data-entry tool | 3-5 screens, 1 role | 18,000 - 28,000 | 5-7 weeks |
| Process management | 8-12 screens, 3 roles, workflow | 32,000 - 50,000 | 9-13 weeks |
| Integrated business portal | ERP + reporting + API | 55,000 - 90,000 | 14-20 weeks |
| Multi-team platform | SSO, audit, 5+ roles | 90,000 - 150,000 | 20-30 weeks |
On top of these amounts comes maintenance of 8 to 15% of the build cost per year, typically EUR 3,000 to 9,000/year for a process-management tool.
Build vs Buy: the real trade-off
Off-the-shelf SaaS is cheaper to start but is paid every month and per user. Custom costs more upfront but becomes an asset. Comparison over 4 years for a 25-person team.
| Criterion | Off-the-shelf SaaS | Custom app |
|---|---|---|
| Upfront cost | EUR 0 - 3,000 | EUR 32,000 - 50,000 |
| Monthly cost | 25-45 EUR/user | 0 (annual maintenance) |
| 4-year cost (25 users) | EUR 30,000 - 54,000 | EUR 44,000 - 68,000 |
| Fit to your business | Low to medium | Total |
| Data ownership | Vendor | You |
| Vendor lock-in | High | None |
Custom wins when the process is specific (impossible to fit into a generic SaaS) or when headcount exceeds 20-30 users, the point where monthly licenses catch up to and then exceed the development cost.
Calculating ROI in hours saved
The ROI of an internal tool is measured in hours freed. The formula is simple: hours saved per month x fully-loaded hourly cost x 12, compared to total cost over 3 years (build + maintenance).
| Task | Before (spreadsheets) | After (app) | Gain/month |
|---|---|---|---|
| Data entry and re-entry | 22 h | 4 h | 18 h |
| Monthly reporting | 12 h | 2 h | 10 h |
| Error corrections | 8 h | 1 h | 7 h |
| Information search | 9 h | 2 h | 7 h |
| Total | 51 h | 9 h | 42 h |
At EUR 35 fully-loaded hourly cost, 42 hours per month represent EUR 17,640 per year in savings. A EUR 40,000 build is therefore paid back in under 30 months, then generates net gains.

Mark, operations director of a 30-employee logistics SME in Toronto, ran his routes across three shared spreadsheets. Scheduling errors, duplicates, 2 hours lost every morning. He invests EUR 38,000 in an internal planning app, delivered in 11 weeks, with maintenance at EUR 4,500/year.
Result: 35 hours saved per month across the planning team, or 420 hours/year. At EUR 35, that's EUR 14,700 in annual savings, not counting fewer customer disputes. The build is amortized in 31 months, then a net gain of EUR 10,200/year. Over 5 years, the balance is positive by more than EUR 30,000.
FAQ
How long to deploy an internal app?
Expect 5 to 7 weeks for a simple tool and 9 to 13 weeks for full process management. ERP integrations extend the timeline by 3 to 5 weeks depending on the quality of available APIs.
At what headcount does custom become more profitable than SaaS?
Generally beyond 20 to 30 users. Below that, a SaaS at EUR 30/user/month often remains cheaper over 4 years, unless your process is too specific for a generic tool.
What maintenance budget should I plan for?
Maintenance of 8 to 15% of the build cost per year, so EUR 3,000 to 9,000/year for a EUR 40,000 app. It covers fixes, security and small enhancements.
Can we start small then expand?
Yes, and it's recommended. We deliver a first scope at EUR 18,000-25,000, validate adoption, then add modules in batches. This reduces risk and spreads the investment.
Who owns the code and data?
With custom, you do entirely: source code, database, hosting of your choice. No vendor lock-in, unlike off-the-shelf SaaS.
