The verdict in three sentences
For a foundation reviewing 800 applications a year, a custom tool at EUR 30,000 to 60,000 (about USD 32,000 to 65,000) becomes cheaper than a SaaS at EUR 15,000 a year by the third or fourth year. Custom makes sense mainly when your scoring rubric is specific, several panels score in parallel and disbursement tracking must match your accounting. Plan for a 4-month project and target 30% less review time, the metric that gets the budget approved by the board.
SaaS or custom tool: the numbers
A foundation's executive director rarely compares two equivalent products. SaaS covers 80% of the standard need (form, document upload, status), custom covers your exact process, including the edge cases SaaS pushes back into Excel.
| Criterion | Grant management SaaS | Custom web app |
|---|---|---|
| Upfront cost | EUR 2,000 to 5,000 setup | EUR 30,000 to 60,000 |
| Annual cost | EUR 15,000 (licenses, 10 to 20 seats) | EUR 4,000 to 8,000 (hosting, maintenance) |
| 5-year total | EUR 77,000 to 80,000 | EUR 46,000 to 100,000 |
| Weighted multi-reviewer rubric | Partial, fixed criteria | Full, weighting per call |
| Tranche-based disbursement tracking | Basic | Schedule, conditions, accounting export |
| Data ownership | With the vendor | With the foundation (your chosen region) |
| Time to go live | 4 to 8 weeks | 4 months |
The tipping point sits around EUR 45,000 of development: above that, custom must deliver a measurable review-time gain to stay defensible.
What a call-for-proposals review tool includes
A controlled scope fits into five modules. Budget varies mostly with rubric complexity and the number of integrations (accounting, e-signature, document management).
| Module | Key functions | Indicative 2026 budget |
|---|---|---|
| Applicant portal | Online submission, attachments, drafts, automatic reminders | EUR 6,000 to 12,000 |
| Review and eligibility | Completeness check, reviewer assignment, comments | EUR 5,000 to 10,000 |
| Multi-reviewer scoring | Weighted criteria, blind scoring, gap summary | EUR 6,000 to 14,000 |
| Disbursement tracking | Agreements, tranches, release conditions, accounting export | EUR 5,000 to 12,000 |
| Reports and dashboards | Interim and final reports, impact indicators, board export | EUR 4,000 to 8,000 |
| Authentication and roles | SSO, per-call rights, audit log | EUR 2,000 to 4,000 |
A base version (portal, review, simple rubric) starts at EUR 30,000. The full version with e-signature and an accounting connector approaches EUR 60,000.
A 4-month plan and success metrics
The typical calendar: 3 weeks of scoping with program officers, 10 weeks of development in two-week sprints, 3 weeks of acceptance testing on a real call. Launch the tool on a mid-sized call before moving the flagship program.
Metrics to track from the first call: average review time per application, share of incomplete files at closing, delay between decision and first payment, number of manual reminders.

Helen, executive director of a family foundation in New York, handles 800 applications a year with 4 program officers. Each file takes 2.5 hours of review on average, or 2,000 hours a year. With a 30% gain she frees 600 hours, roughly EUR 27,000 (about USD 29,000) of loaded staff time at EUR 45 an hour. Her custom tool costs EUR 48,000 plus EUR 6,000 a year of maintenance. Against the SaaS at EUR 15,000 a year, the cost gap closes in 3.2 years, and the time saved pays back the project in under 2 years.
FAQ
How much does a custom grant management app cost in 2026?
Budget EUR 30,000 to 60,000 (about USD 32,000 to 65,000) depending on the rubric and integrations. Maintenance and hosting then run EUR 4,000 to 8,000 a year.
How long does it take to go live?
About 4 months, including 3 weeks of scoping and 3 weeks of testing. A pilot call can run from month four.
Can we migrate our existing application history?
Yes, migrating from Excel or a previous SaaS costs EUR 2,000 to 5,000 depending on data quality. Plan one week of cleanup on the foundation side.
Do external reviewers need an account?
A secure, time-limited link is enough for scoring, with a one-time code sent by email. Rights are limited to assigned files, which simplifies privacy compliance.
Is a 30% gain realistic?
It is a 2026 order of magnitude seen when completeness is checked automatically and score summaries are computed. Without those two functions, the gain drops to 10 to 15%.
