The verdict in three sentences
Above 5,000 members and 1,500 donors, spreadsheets and manual receipts become a real risk: wrong amounts, duplicates, and weak records when Revenue checks your charitable donation scheme claims. An off-the-shelf tool at 50 - 300 EUR a month is enough if your flows are standard (annual membership, one-off gifts, simple SEPA direct debit). A custom donor CRM at 40,000 - 100,000 EUR makes sense when you run several branches, tiered memberships, legacies or specific accounting integrations.
What a large charity's software must do in 2026
The treasurer of a 6,000-member charity does not want a generic CRM. They need four things: a single record per person (member, donor, volunteer, often all three), membership fees collected by SEPA direct debit with no re-keying, annual donor statements and tax relief data generated automatically, and demonstrable GDPR compliance on donor data.
| Function | Spreadsheet + manual work | Off-the-shelf tool | Custom software |
|---|---|---|---|
| Single member / donor record | Frequent duplicates (5 to 10%) | Yes, basic deduplication | Yes, tailored merge rules |
| SEPA direct debit for fees | Bank file prepared by hand | Yes, e-mandates | Yes, multiple schedules and returns handled |
| Donor receipts and tax relief data | 2 to 5 minutes per donor | Annual batch | Annual batch + real-time receipts |
| Multi-branch management | One file per branch | Depends on plan, often extra | Branch-level rights and consolidation |
| Accounting export | Copy and paste | Standard export | Entries in your accounting software format |
| GDPR register and consents | Missing | Partial | Consent log and automatic purge |
| 2026 cost (estimate) | Volunteer time | 50 - 300 EUR / month | 40,000 - 100,000 EUR + 5,000 - 12,000 EUR / year |
Key point on tax: under the Irish charitable donation scheme, gifts of 250 EUR or more per year let the charity claim relief, which requires clean records per donor (enduring certificates, amounts, dates). Software that compiles the claim file in one click saves days of reconstruction.
Off-the-shelf or custom: the numbers
For a charity of this size, the question is budget and organisation, not technology. The table compares five-year total cost.
| Criterion (5 years) | Entry-level off-the-shelf | Advanced off-the-shelf | Custom software |
|---|---|---|---|
| Subscription or licence | 50 EUR / month, 3,000 EUR | 300 EUR / month, 18,000 EUR | 0 EUR |
| Initial build | 0 EUR | 3,000 - 8,000 EUR configuration | 40,000 - 100,000 EUR |
| Maintenance and hosting | Included | Included | 5,000 - 12,000 EUR / year, 25,000 - 60,000 EUR |
| Fee on online donations | Often 0 to 2% | 0 to 1% | Payment fees only (about 0.3 to 1.5%) |
| Fit with internal rules | Low | Medium | Full |
| Ownership of data and code | Data exportable | Data exportable | Code and data are yours |
| Indicative 5-year total | 3,000 - 6,000 EUR | 21,000 - 26,000 EUR | 65,000 - 160,000 EUR |
The reading is simple: if an advanced tool covers 90% of your needs, take it. Custom pays off when workarounds cost more than 12,000 to 15,000 EUR a year in staff time, or when platform fees on online giving exceed that amount (1.5% on 800,000 EUR of online gifts is 12,000 EUR a year).
GDPR and donor data: requirements for your specification
Donor data often reveals beliefs or opinions (the cause supported, religious or political affiliation). The Data Protection Commission expects proportionate measures. Put in your specification:
- an exportable record of processing and the legal basis for each use (membership, appeals, newsletter);
- automatic purge of inactive prospects after 3 years without contact;
- role-based access: a branch volunteer cannot see gift amounts;
- EU hosting, logged exports and encrypted IBANs.
These items add roughly 10 to 15% to the build budget, but they prevent enforcement action and protect donor trust.

Aoife, volunteer treasurer of a social and cultural charity in Dublin (6,000 members, 2,000 donors), prepares 2,400 donor statements a year by hand at 3 minutes each: 120 hours. Add 15 hours a month reconciling SEPA debits and returns, 180 hours a year. Total: 300 hours, about 10,500 EUR of loaded staff time if the charity had to pay for it.
Chosen scenario: custom software at 60,000 EUR, with 7,000 EUR a year for maintenance and hosting. Time spent falls to 40 hours a year. Annual value of time saved is about 9,100 EUR, plus 7,500 EUR of avoided platform fees on 500,000 EUR of online gifts. Payback: roughly 6 years on cost alone, shorter once better tax relief claims and fewer lapsed members are counted, with a clean database and an audit file ready in an hour.
FAQ
How much does a custom donor CRM cost in Dublin in 2026?
Expect 40,000 to 100,000 EUR depending on modules (members, gifts, SEPA, receipts, branches). Maintenance then runs at 5,000 to 12,000 EUR a year, EU hosting included.
Can the software prepare charitable donation scheme claims automatically?
Yes. It tracks enduring certificates, flags donors above the 250 EUR threshold and compiles the annual claim file. Donors receive numbered PDF statements by email.
How is SEPA direct debit handled?
The software stores e-mandates, generates the debit file for your bank and imports returns. On 6,000 members, a 2% return rate means 120 follow-ups that can be automated.
How long does it take to go live?
Usually 3 to 5 months: 4 weeks of scoping, 8 to 12 weeks of build, then 2 to 4 weeks of data migration and testing. Starting in June lets you run the next year's statements on the new tool.
Do we still need a platform for online giving?
Not necessarily. The donation form can sit on your own website with a payment provider, keeping fees around 0.3 to 1.5% per transaction.
