Pros & Cons
CiviCRM

Pros
- The core software is free and open source under the AGPL, so there are no licence fees whatever the number of users or contacts.
- Donations, memberships, events, CiviMail email and case management all come in one nonprofit-focused system.
- It runs inside WordPress, Drupal and Joomla, so data is shared between the website and the CRM.
- Every Spark hosted plan allows unlimited users, starting at $15 per month.
- A large extension ecosystem and an active community make it highly customisable.
Cons
- Reviewers consistently describe the interface as dated and clunky.
- Self-hosted setup and customisation usually need a developer, which adds hidden costs.
- The open-source project offers no dedicated vendor customer service. Help comes from community forums or paid partners.
- Spark plans cap contacts at 5,000 to 10,000 and limit integrations and customisation.
- It has no sales pipeline or opportunity tooling for commercial sales teams.
Sellsy

Pros
- Quotes convert to invoices without retyping, and quotes can be signed electronically in the same tool.
- Approved French e-invoicing platform included on every plan, ahead of France's e-invoicing reform.
- Data hosted in France, ISO 27001 certified, GDPR compliant, with daily backups.
- French-language chat support on every plan from an in-house team, plus phone support on higher tiers.
- More than 100 marketplace apps, including French accounting software and bank sync with Qonto.
Cons
- 12-month commitment even on monthly billing, and a 2-user minimum on the bundle.
- Reviewers say the interface is busy and takes about a week to learn.
- Cash management and advanced marketing tiers cost extra on top of per-user licences.
- Built around French accounting rules, so it fits non-French companies less well.
- Users report pricing changes, some invoicing glitches and duplicate contacts from Google sync.
