Zoho vs Sellsy 2026

Sellsy edges this at 3.4 vs Zoho's 3.2, and the gap is small but consistent. Zoho's interface is widely described as dated: cluttered navigation, module structures that take 10-15 hours of active use before users feel comfortable, and a 2025-2026 UI refresh ("CRM for Everyone") that helps new teamspaces but leaves most Standard and Professional users on the legacy layout. In testing with a non-technical sales team, a full week of daily use was needed before the CRM felt natural.

Sellsy takes roughly 1 week to learn too, but basic operations get easier faster. Quote creation, document templates and the e-signature module (all 5 test clients signed in under 10 minutes in our test) give sales teams quick wins in the first days. The honest bémol: Sellsy's navigation between modules like CRM, invoicing and pre-accounting is not seamless, and advanced features like segmentation and custom reports need extra training sessions. Neither tool wins on raw UX, but Sellsy's commercial document flow tips the round.

Zoho wins this by a wide margin at 4.7 vs 3.2. The numbers are stark: Zoho Standard is $14/user/month vs Sellsy Standard at €39/user/month. For a 5-user team on Standard, Zoho costs around $840/year (~€770 at current rates), while Sellsy costs €2,340/year. That is roughly a 3x difference at entry level. Zoho also offers a permanent free plan for 3 users, while Sellsy only offers a 15-day trial.

The honest counter-argument: Sellsy bundles invoicing, e-signature and DGFiP-certified e-invoicing in its base plan. If a French company would otherwise pay for a separate certified invoicing platform, Sellsy can consolidate that cost. But the math only works for teams where the PA certification is mandatory. The other documented bémol on Sellsy: progress invoicing has bugs (negative amounts, inconsistent down payment allocation confirmed in hands-on testing, June 2026), which erodes value for service businesses. Zoho's Zia AI is locked behind the Enterprise tier at $40/user/month, meaning the value case weakens on lower plans.

Zoho takes this narrowly at 4.3 vs 4.2. The breadth of the Zoho ecosystem is the main reason: 45+ apps (CRM, Mail, Books, Desk, Campaigns, Analytics, Projects) sharing data natively, Deluge scripting for custom logic, and Zia AI with 22 capabilities including deal scoring, churn prediction, call transcription and generative drafting on Enterprise tier. In testing, a 12-step lead nurturing workflow was built without code in a single session.

Sellsy's differentiator is the commercial document cycle: native quote creation, e-signature (reliably fast in testing), and DGFiP-certified e-invoicing that Zoho CRM simply does not offer. The documented weaknesses on Sellsy: workflow automation is limited (accepted quotes do not auto-advance opportunities to "won" status, requiring a manual step), Office 365 contacts sync only in one direction (Sellsy to O365, not back), and Exchange accounts are not supported. Sellsy AI is described as text generation only, not true automation intelligence. Neither tool is perfect for feature depth, but Zoho's automation engine and AI stack pull it ahead.

Sellsy wins support clearly at 4.1 vs Zoho's 3.5. Sellsy offers French-language live chat on Evolution and Elite plans, with under-10-minute wait times confirmed in testing. Email support averages 4-6 hours in French, and personalised onboarding sessions are included on Evolution and above. In 4 support tickets over 3 months, all were resolved in under 6 hours with relevant, French-language answers.

Zoho's support picture is weaker: no live chat exists on any plan (a notable gap in 2026 when most competitors offer it). Phone support on Professional+ is available by scheduled callback only, which defeats the purpose for urgent issues. The knowledge base holds 400+ articles but is poorly organised, with one 45-minute search needed to find custom function documentation buried in forum threads. Email response runs 24-48 hours. Three of four tickets submitted over 6 months were resolved satisfactorily on the first contact; one required 4 days of back-and-forth. The honest caveat on Sellsy: its community forum is less active than HubSpot or Salesforce equivalents, and chat access is gated behind Evolution/Elite plans.

Zoho takes integrations at 4.2 vs Sellsy's 3.9. The 2,000+ Zoho Marketplace extensions across 40+ categories versus Sellsy's 100+ covers almost any standard business stack. In 6 months of testing, Slack, Google Drive, WordPress, Stripe and Shopify all integrated with zero configuration issues beyond standard OAuth. The REST API with SDKs in Python, JavaScript, PHP and Java enabled a custom webhook integration with a proprietary client system in under 8 hours.

Sellsy's integration story is narrower but targeted: Aircall telephony (tested with a 6-person sales team: immediate adoption), Order Invoicer for Shopify, WooCommerce and PrestaShop, and Tiime for pre-accounting. These are exactly the tools French SMBs use. Where Sellsy falls short: no native Slack, no Notion, no advanced LinkedIn integrations, and Office 365 contacts sync only goes one way. The Zoho internal ecosystem is the real differentiator: CRM, Books, Desk, Campaigns and Analytics share data natively, eliminating entire integration layers for Zoho-first teams. For integration breadth and developer extensibility, Zoho wins clearly.
