HubSpot vs Sellsy 2026

HubSpot takes this 4.5 to 3.4, and the gap is real. We had clients sending their first email campaigns within 48 hours of account creation, using HubSpot's drag-and-drop builders for emails, landing pages, and workflow logic. The contact record view consolidates the full interaction history in one scrollable interface, and the AI-powered content summarization in the sidebar genuinely helps reps prepare for calls. Non-technical marketers can build landing pages and sequences in under three hours, no code required.

Sellsy requires 2 to 3 hours just for initial pipeline and template configuration. Sales teams need about 45 minutes for the basics, then two or three additional sessions to feel comfortable with advanced features. The navigation between CRM, invoicing, projects, and accounting modules involves multiple clicks, and the interface is described by users as slightly dated compared to modern competitors. The 360-degree client view and electronic signature are genuinely useful once you're set up, but the first week is rougher.

The honest caveat on HubSpot: advanced reporting and multi-branch workflows with 15+ conditional steps take real time to master. But for speed-to-value, it consistently wins.

HubSpot edges this 3.5 to 3.2, and it comes down almost entirely to the free tier. A permanent free CRM with unlimited contacts and deal tracking that requires no credit card is a structural advantage that Sellsy simply cannot match (15-day trial, then minimum €98/month).

But the comparison inverts at scale. For a 5-person team needing CRM plus invoicing, Sellsy Evolution (5 x €89) runs €445/month against HubSpot Sales Hub Pro plus Commerce Hub Pro (5 x $90 plus 5 x $57 = $735/month, roughly €675). Sellsy is around 40% cheaper for the same CRM and invoicing functionality at five users. At 10 users needing CRM, invoicing, and treasury, Sellsy Evolution plus the Treasury add-on runs roughly €1,049/month against an estimated €2,757/month for a comparable HubSpot stack.

Neither tool scores high here because both have real escalation traps. HubSpot's hidden costs are well documented: mandatory onboarding fees ($1,500 for Sales Pro, $3,000 for Marketing Pro), contact tier escalation, and the new HubSpot Credits consumption layer added in June 2025. Sellsy's pricing confusion (many sites still show the outdated €35 figure; the real 2026 Standard is €49/user) damages trust. HubSpot wins only because the free entry point is genuinely useful.

HubSpot takes this 4.5 to 4.2, with its breadth across Marketing, Sales, Service, Content, and Commerce Hubs covering the entire customer lifecycle. The 1,700+ native integrations and Breeze AI suite (Buyer Intent signals, Prospecting Agent, Data Agent enrichment, conversation intelligence) are genuinely production-ready differentiators that save 5 to 10 hours per week in our agency work. Marketing Hub's behavioral workflows, A/B landing pages, and predictive lead scoring are features Sellsy does not offer at any price point.

Sellsy's depth is concentrated and impressive in its lane: 360-degree client database with 15+ custom fields, up to 20 pipelines on Evolution, native Factur-X invoicing, pre-accounting export via Tiime, treasury cash management, and CICE/FEC compliance. Electronic signature is tested and fast (clients signed in under 10 minutes in every case we ran). These are features HubSpot simply does not have at any tier, not because they are niche, but because HubSpot is built around marketing-led growth, not financial operations.

Sellsy's AI add-on is limited to text generation, with no predictive scoring, no intent signals, and no call intelligence, putting it well behind HubSpot's Breeze stack in that dimension.

Sellsy takes this narrowly, 4.1 to 4.0, because its support is structurally French-first in a way HubSpot's cannot be. We contacted Sellsy support four times over three months: response time averaged 4 to 6 hours by email, always in French, always with a relevant solution. Live chat on Evolution plans had us connected in under 10 minutes. A dedicated account manager on Elite and a personalized one-hour onboarding call on Evolution genuinely accelerate adoption.

HubSpot's support quality scales with your subscription in a way that creates real friction. Free users get community and docs only, no direct channel. Professional unlocks email and phone, but we saw 18 to 24-hour email response times consistently. The support hub is Dublin-based and English-primary; French documentation exists, but agents default to English, which creates friction for non-English speakers. HubSpot Academy is a genuine advantage that Sellsy cannot match: world-class free certifications across all hubs that accelerate self-service learning.

The honest caveat: Sellsy's community forum is far less active than HubSpot's ecosystem, and no chat support on Standard reduces the advantage for teams on the entry plan.

HubSpot wins this clearly, 4.5 to 3.9, on raw catalog size and API quality. The 1,700+ native integrations (some sources cite 1,000+; the March 2026 Ceres Agency analysis cites 1,700+) cover virtually every business software category, and most install via OAuth in under 5 minutes without developer skills. Sellsy has around 80 to 100 native integrations.

Sellsy does cover French SME essentials well: Aircall telephony integration works perfectly and was immediately adopted by every team we tested it with; Tiime handles pre-accounting export; Order Invoicer connects WooCommerce and Shopify orders directly to Sellsy invoicing. Zapier and Make extend the catalog for custom flows. For the typical French SME stack, this is usually enough.

The gaps become visible at scale: Sellsy lacks native Slack, Notion, and advanced LinkedIn Sales Navigator integrations that HubSpot handles natively. For the Spanish market specifically, Sellsy's integration ecosystem is France-centric and compatibility with Spanish ERP or accounting tools is unverified from official sources. HubSpot's API is well-documented, REST-based, and used in production by companies across 100+ countries without friction.
