Pros & Cons

CiviCRM logo
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.
