The verdict in three sentences
For a foundation handling 800 applications a year and granting EUR 4M, a custom grant management platform at EUR 35,000 to 70,000 excluding VAT pays off by year three against a specialised SaaS billed EUR 8,000 to 25,000 a year. The real gain is review time: from 3 hours to 1 hour 15 per application, roughly 1,400 hours freed every year. Custom makes sense when your committees, grant agreements and impact reports do not fit a standard tool.
What a grant platform must cover in 2026
A corporate foundation does more than collect forms. It runs a full cycle: call for proposals, eligibility, review by volunteer experts, selection committee, grant agreement, staged payments, indicator tracking and reporting to the board. Each step produces documents and decisions that must stay traceable, especially for the statutory auditor and for French corporate philanthropy rules (receipts, counterparts, article 238 bis of the tax code).
| Module | Key function | Share of custom budget | Development time |
|---|---|---|---|
| Calls for proposals | Dynamic forms, automatic eligibility rules | 15% | 3 weeks |
| Review | Scoring grid, reviewer assignment, comments | 20% | 4 weeks |
| Committees | Agenda, voting, generated minutes | 12% | 2 weeks |
| Agreements | Templates, e-signature, amendments | 13% | 2 weeks |
| Payments | Schedule, release conditions, accounting export | 15% | 3 weeks |
| Impact reports | Indicators per programme, collection from grantees | 15% | 3 weeks |
| Steering | Dashboards, board exports | 10% | 2 weeks |
Plan for 14 to 20 weeks in total, including acceptance testing. A first release limited to calls, review and committees can ship in 9 weeks, in time for the next campaign.
Custom or specialised SaaS: the numbers
Grant management SaaS products are mature and cover the core process well. Their limits show on specific scoring grids, milestone-based payments, integration with the founding group's IT and data ownership.
| Criterion | Specialised SaaS | Custom platform |
|---|---|---|
| Upfront investment | EUR 2,000 to 8,000 setup | EUR 35,000 to 70,000 excl. VAT |
| Annual cost | EUR 8,000 to 25,000 (per user or per application) | EUR 4,000 to 9,000 (hosting, maintenance) |
| 3-year total | EUR 26,000 to 83,000 | EUR 47,000 to 97,000 |
| 5-year total | EUR 42,000 to 133,000 | EUR 55,000 to 115,000 |
| Specific review workflow | Partial, vendor-dependent | Full |
| Group IT integration (SSO, accounting) | Standard connectors | Custom, API |
| Data hosting | Often outside France | France, your choice of host |
| Go-live | 4 to 8 weeks | 14 to 20 weeks |
Rule of thumb: under 300 applications a year with a standard process, SaaS remains the best choice. Above 600 applications, with several programmes and separate committees, custom wins from year four and removes the Excel workarounds.
What derails a project
Three topics cause most overruns. First, historical data migration: importing 5 years of applications from spreadsheets and mailboxes takes 5 to 10 days of work that belongs in the quote. Second, GDPR: applications contain personal data of project leaders and sometimes beneficiaries, which requires retention periods, a processing register and role-based access. Third, volunteer reviewer adoption: a scoring flow longer than 10 minutes drives the return rate down. A mobile interface and automatic reminders lift that rate from 60% to over 90% (2026 order of magnitude).

FAQ
How much does a custom grant management platform cost in 2026?
Expect EUR 35,000 to 70,000 excluding VAT depending on the number of programmes, committee complexity and integrations. Maintenance and hosting add EUR 4,000 to 9,000 a year.
Can we start with a smaller scope?
Yes. A first release covering calls, review and committees costs about EUR 22,000 to 30,000 excluding VAT and ships in 9 weeks. Agreements, payments and impact reports follow in a second release.
Do external reviewers need an account?
A secure limited-use link is enough in most cases. Review return rates then exceed 90%, against 60% with a mandatory account.
Can the platform generate tax receipts and accounting exports?
Yes, exports to the group's accounting software and payment documents are part of the payments module, about 15% of the budget.
Where is the data hosted?
In France, with an HDS or ISO 27001 certified host if needed, for EUR 150 to 400 a month depending on volume and backup level.
