The day two people keep the same member list in two different spreadsheets, the association needs a CRM. Not sales software: a shared contact base, with the history of each relationship. This guide gives the method to choose it without spending six months on it, and so that it is still maintained in two years.
Belgium counts about 147 000 non-profit associations according to Belfirst data reported by Guide Social, and most keep their members, donors and volunteers in separate files, often with several people. That is not a problem as long as the association is small and stable. As soon as the team changes, membership fees need reminders or donations must produce a certificate, the file becomes a risk: duplicates, dead addresses, data kept for no reason. A CRM is first an answer to that risk.
Answer these questions on one page:
This page is your specification. It already eliminates half the tools, and it serves as a contract with the team: what is not on it will not be in the CRM in the first year.
Up to a few dozen contacts and a single person keeping it, an online spreadsheet with fixed columns, one line per contact and a "last exchange" column is enough. Beyond that, or as soon as several hands touch it, it creates duplicates and losses, and it cannot produce a certificate or a reminder.
Consumer tools, free or a few euros a month, made for small structures, with a web form, tags, a history and email sending. They fit when the need is mostly to centralise and remind, and when donations are rare.
Tools designed for associations, with management of membership fees, donations, receipts, campaigns and sometimes events. They are justified when donations are regular or members are numerous, and they require a more serious set-up: a few days of configuration and a training. Some are open source and hostable by you, others are rented monthly.
Keep three candidates, not ten. For each, test on your real data: import fifty contacts, create a membership fee, send a reminder, export a list, delete a person who asks for it. Note the time it takes your referent, not the most tech-savvy person. Also check three things demos forget: where the data is hosted (in Europe, preferably), how you export everything if you leave the tool, and what the following year costs.
A CRM helps you comply with the GDPR if you set the rules at the start: what you collect and why, how long you keep it, who accesses it, how a person requests their data or its deletion. Write these rules in your privacy policy and in your record of processing activities, which even a small non-profit must keep as soon as it processes data regularly. The glossary sums up the GDPR. One simple rule that avoids a lot of trouble: only collect what you will use within the year.
It is the most useful case and the most often forgotten: the membership, donation or registration form on the website feeds the base without retyping, with the consent notice in the right place. Plan it when the website and the CRM are designed together; wiring it afterwards costs more. The guide Redoing your association's website explains where that form fits.
The spreadsheet costs nothing. A simple general CRM is free for a few users, then a few euros a month per user. A non-profit CRM is paid by monthly subscription or by installation, plus a few days of configuration, whether you do them yourself or with a provider. The real cost is elsewhere: the time to clean the list, to train two people and to keep the weekly ritual. A free tool nobody maintains costs more than a paid tool that is maintained. In Kern4Good, scoping, set-up and training are done as at-cost consulting, on quote, and we say when the spreadsheet is still enough.
Only institutions approved by the FPS Finance issue tax certificates for donations, and they must transmit those certificates electronically to the administration every year. If your association is approved, or intends to apply, your CRM must be able to produce the list of eligible donations with the donors' exact data: it is a selection criterion, to state on the needs page. If it is not, say so clearly on your website and in your thank-you notes, so as to promise nothing you cannot keep.
The Kern4Good programme helps with these steps through at-cost consulting, on quote: the CRM for non-profits page explains what is offered. The glossary defines the CRM.
Pages consulted on 19 September 2026. Rates, ceilings and percentages change: check the update date of each page before building a budget on it.
The one that passes the test on your data with your referent. We do not name a single one here because the right choice depends on your size, your donations and your website. That is what the scoping is for.
Many do, or link to a sending tool. Put it in your needs page if it matters to you, with unsubscribe management.
With a clean list and an available referent, a few weeks. Cleaning the list is what takes the most time; start there.
As soon as you process personal data regularly, yes, and a member list is one. It fits on one page: which data, why, who accesses it, how long.
To centralise and remind, often yes. Check where the data is, how you export it and what becomes of the tool if the publisher changes its terms. For donations and certificates, a non-profit tool is justified.
When to redo it, what to keep, what to write before talking design, which tool, how much it costs (from 0 to 8 000 EUR, at cost) and how to fund it. A guide for the team carrying the project, without jargon.
Prime Digitalisation in Brussels, Walloon vouchers, kmo-portefeuille in Flanders, foundation calls: what exists, under which conditions, why non-profits are often excluded, and how to check before counting on it. Official sources cited.
Search visibility is not a task in the quote, it is regular work. What the technical base covers, what real visibility requires (content, links, GEO) and how many days a month to devote to it, on your side or ours.
