nextesy vs. bexio: the best accounting software for Switzerland compared (2026)

As of: September 2026. Prices and features may have changed since.

1. Artificial Intelligence in Accounting: nextesy Leads the Way

Automation is the key difference between the two solutions.

nextesy is built from the ground up as an AI-native tool. Invoices are generated in seconds, dunning runs automatically, and Swiss bank accounts are directly integrated. Once set up, nextesy reconciles transactions automatically without requiring manual intervention.

bexio offers "AI posting of QR invoices & receipts" starting from the Advanced plan, with a monthly scan allowance: 50 scans in Advanced, 100 in Optima, unlimited (fair use) in Ultimate. It is not included in the Basic plan. In 2025, bexio announced the acquisition of Kontera to expand its AI capabilities, though full integration is still underway.

What this means for you: If you prioritise automation, nextesy saves you actual hours every month. Benchmark from the Swiss market: AI-assisted accounting solutions reduce administrative effort from several hours down to 15 to 30 minutes per month. bexio is a solid cloud tool, but its depth of AI integration is currently significantly lower.

→ For the self-employed and small teams without prior accounting knowledge, nextesy’s AI advantage translates into a real, measurable day-to-day benefit.

2. Ease of Use: Getting Started Without Prior Knowledge

No prior knowledge required. That is the promise of both providers. In practice, however, differences emerge.

nextesy is explicitly geared towards self-employed professionals and small businesses without an accounting background. The user interface is engineered for automation: receipts are recognised, accounts are suggested, reconciliations are completed. You confirm instead of typing.

bexio has been on the market since 2013 and has reached a mature product stage. The interface is familiar to many Swiss SMEs. For beginners, however, the complexity of certain processes can present a hurdle.

Support in comparison: bexio scores only 2.2 out of 5 stars for customer support on Capterra (as of 2026). Users report a so-called "call-first culture" when cancelling subscriptions. This serves as a warning sign for anyone who values straightforward customer support. Google reviews reflect a similar picture: across more than 2,000 reviews, the average rating stands at just 3.9 stars as of September 2026.

nextesy is a younger company with around 40 employees across 3 locations. The team size enables direct contact and fast turnaround times on feedback. Those who value dedicated, personal support will appreciate this. nextesy's Google reviews confirm it: customers award nextesy an average of 4.8 stars, with quality of support highlighted particularly often. nextesy’s internal metrics also confirm this: the customer satisfaction rate among clients who have opened a ticket stands at over 85% in 2026 (as of September), and on average, tickets receive a response within less than 3 hours. 

3. Feature Scope: What Do You Really Need?

Both tools meet standard Swiss requirements: double-entry bookkeeping, QR-bills (mandatory since October 2022), VAT accounting compliant with ESTV guidelines. However, their feature sets beyond these basics differ substantially.

What nextesy covers: Invoicing, dunning, Swiss bank feeds, automated transaction reconciliation, payroll accounting (AHV, ALV, BVG, withholding tax), CRM with Zefix integration, and document management. No modules need to be booked separately; additional costs are incurred solely for payroll employees exceeding the included package quota. nextesy's degree of automation already exceeds 60%, meaning that only 40% of postings require manual entry.

What bexio offers in addition: Inventory management, projects and time tracking (starting from the Optima plan), and the bexio Marketplace offering over 50 to more than 100 verified business apps, depending on the plan. bexio provides broader functionality overall.

Notable gaps in bexio (as of September 2026):

• Cost centres are completely missing. Those requiring cost centres must turn to other solutions.

• Payroll accounting is not available in the Basic plan. In Advanced and Optima, it is a paid add-on module (from CHF 7 or CHF 25 per month, depending on the number of employees). Only the Ultimate plan includes payroll for up to 25 employees.

• Bank feeds are not included in bexio's entry-level plan and are only available starting with the Advanced package.

• AI receipt posting is not included in the Basic plan and is capped at 50 or 100 scans per month in Advanced and Optima, respectively.

nextesy offers a more focused feature set. For the self-employed and SMEs, this proves more than sufficient in most cases. Those with complex ERP requirements are better served by bexio or alternative solutions.

4. Product Development: Rapid Innovation vs. Pending Modernisation

nextesy was founded in September 2023 and is currently in a phase of rapid development. The company raised CHF 3.3 million in pre-seed funding from Fifth Quarter Ventures and business angels. AI forms the backbone of the platform, connecting every single feature. Development focuses on continuously rolling out new features in close collaboration with customers. New functionality is typically released every two weeks.

bexio was founded in 2013 and has been active on the market for over a decade. The solution belongs to the cloud generation of the early 2010s and has reached a stable, mature product state over this period. Viewed from the outside, its strategic focus currently lies primarily on marketplace expansions.

What this means: bexio is stable and time-tested. nextesy is more agile and considerably closer to modern AI standards. If you prioritise up-to-date technology and automation, nextesy is the better fit. If you value established reliability and an extensive ecosystem with numerous third-party integrations, bexio delivers that.

5. Price-to-Performance: Direct Comparison

On 1 March 2026, bexio rebranded its plans and raised prices. The entry-level package increased by approximately 16% compared to the previous Starter price.

With monthly billing, bexio costs CHF 45 / CHF 52 / CHF 79 / CHF 129 per month, while nextesy costs CHF 44 / CHF 79 per month.

Actual costs with bexio: The entry-level package sounds affordable at first, but quickly becomes complex and remains heavily restricted. Bank feeds are only included from the Advanced plan upwards. Payroll comes as a separate add-on tiered by employee headcount. Time tracking is not available until Optima. Depending on requirements, add-on modules add up fast, requiring close attention to keep track of true overall expenditure.

nextesy includes bank feeds and SME payroll accounting starting from CHF 29/month in the Plus plan. Additional expenses occur only for payroll employees beyond the package quota (from 2 employees in the SME plan, from 4 in the Pro plan). These represent the only variable costs that may apply.

6. Integrations: bexio Delivers Breadth, nextesy Builds In-House

bexio is the undisputed market leader in this regard. Over 100 verified business apps can be connected via the bexio Marketplace: from online shops and POS systems to industry-specific tools. Nearly every Swiss fiduciary is familiar with bexio, and its fiduciary portal is well established. This is a genuine advantage for growing SMEs with complex workflows.

nextesy is newer and offers fewer third-party integrations, yet covers many functions of external tools natively within the core product. The Zefix integration within the CRM is a practical Swiss-specific feature. For the vast majority of small companies and sole traders, nextesy’s built-in scope of integration is more than adequate for daily operations.

Who does this matter for? If you rely on specific third-party systems—such as a dedicated e-commerce store, a POS system, or a niche industry application—you should evaluate the bexio Marketplace carefully. nextesy has already built the most essential integrations directly into its own software. Users who do not depend on a specific third-party provider, but simply need the underlying functionality, will find nextesy easier to navigate thanks to its cohesive design and seamless feature connections. 

Both providers support all primary Swiss requirements: QR-bills, VAT, and CHF invoicing.

7. Support and Fiduciary Compatibility

As the market leader with over 100,000 customers according to company figures (as of 2025), bexio runs a large customer support operation. At the same time, its Capterra rating of 2.2 out of 5 stars for customer support (as of 2026) demonstrates that size does not automatically guarantee quality service. Users report difficulties regarding contract cancellation and poor day-to-day accessibility.

With around 40 employees, nextesy is significantly leaner. This enables direct contact and fast response times; callers to nextesy support typically wait on hold for less than 30 seconds before speaking to an agent. The company is led by five co-founders with direct domain expertise across finance, sales, AI, accounting, and software engineering. The team is advised by institutions such as the ETH AI Center, HSG, Innosuisse, and LMU Munich.

For fiduciaries: bexio has long been the established standard among Swiss fiduciaries. However, keeping pace with evolving demands—particularly the drive towards greater efficiency—is proving increasingly difficult for bexio over time. The absence or slow pace of ongoing product evolution is prompting fiduciaries to evaluate alternative solutions more closely. 

nextesy was initially developed specifically for the fiduciary sector before expanding its focus to SMEs. Thanks to close collaboration with fiduciary partners, nextesy is well on its way to establishing the new industry standard. Its dedicated fiduciary module features mandate management, real-time collaboration, and additional workflow tools.

8. Conclusion: Which Software Suits You?

Choosing between nextesy and bexio comes down to your operational priorities.

nextesy is the right choice if you:

Anyone switching from another product to nextesy benefits from the switch tariff: nextesy costs just CHF 1 per month until your notice period with your previous provider has ended.
