Pros & Cons
Apollo
Pros
- Prospect database, email sequencing, dialer and enrichment come in one subscription, so teams buy fewer tools.
- The free plan has no time limit and lets a team try the full prospecting workflow.
- Reviewers rate ease of use highly, and G2 shows about 4.7 out of 5 from roughly 9,700 reviews.
- Admins can pool credits across the team and set per-user caps.
Cons
- Many reviews report inaccurate data, especially mobile numbers and contacts outside North America.
- Credits expire each cycle, phone reveals cost about eight times as much as an email, and credits are spent even on bad records.
- Support is the lowest-rated G2 subcategory, and Trustpilot shows a TrustScore of about 3.1.
- API access and SSO require the top Custom plan, and every seat must be on the same plan.
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.
