nextesy vs. bexio: The best accounting software for Switzerland in comparison (2026)

Status: 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 was built from the ground up as an AI-native tool. Invoices are created in seconds, payment reminders run automatically, and Swiss bank accounts are connected directly. Once set up, nextesy reconciles transactions automatically without requiring your intervention.

bexio offers receipt recognition in its mobile app, bexio Go. However, deeply integrated AI is missing on desktop or for email imports. In 2025, bexio announced the acquisition of Kontera to expand its AI capabilities, but full integration is still underway.

What this means for you: If you prioritise automation, you save real hours each month with nextesy. Benchmark from the Swiss market: AI-powered accounting solutions reduce effort from several hours to 15 to 30 minutes per month. bexio is a solid cloud tool, but as things stand today, its AI capabilities run significantly less deep.

→ For the self-employed and small teams without prior accounting knowledge, nextesy's AI edge delivers a real, measurable day-to-day benefit.

2. User-friendliness: start without prior knowledge

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

nextesy is explicitly aimed at self-employed individuals and small businesses who have no formal accounting background. The user interface is designed for automation: receipts are recognised, accounts are suggested, reconciliations are carried out. You simply confirm instead of typing.

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

Support comparison: bexio achieves only 2.2 out of 5 stars in the support category on Capterra (as of 2026). Users report a so-called «call-first culture» when cancelling subscriptions. This is a warning sign for anyone who values straightforward customer care. Google reviews paint 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 allows direct contact and fast responses to feedback. Anyone who values personal support will appreciate this. nextesy's Google reviews underline the point: customers give nextesy an average of 4.8 stars, with quality support frequently highlighted. nextesy's internal data also confirms this: the customer satisfaction rate for customers who opened a support ticket exceeds 85% in 2026 (as of September), and on average, users receive a response within under 3 hours of opening a ticket. 

3. Scope of features: what do you really need?

Both tools meet core Swiss requirements: double-entry bookkeeping, QR-bills (mandatory since October 2022), VAT accounting according to ESTV specifications. Beyond that, however, the scope differs significantly.

What nextesy covers: Invoicing, dunning, bank feeds with Swiss banks, automatic transaction matching, payroll accounting (AHV, ALV, BVG, withholding tax), CRM with Zefix integration, and document management. All included, with no add-on modules. nextesy's level of automation is already over 60%, which means only 40% of bookings are created manually.

What bexio offers additionally: CRM, inventory management, time tracking (starting from the Optima plan), and a marketplace with over 100 verified integrations. bexio is functionally broader.

Key gaps in bexio (as of September 2026):

• Cost centres are completely missing. Anyone needing cost centres must turn to other solutions.

• Payroll accounting is a paid add-on module in bexio, tiered by the number of employees. It is only included for up to 25 employees in the Ultimate plan.

• Bank feeds are not included in bexio's entry-level plan, but only starting from the Advanced plan.

• AI bookkeeping is currently only possible with an additional Kontera account. This comes with extra costs starting from CHF 14 per month, and receipt processing takes place across two separate tools.

nextesy features a more focused range of functions. For sole proprietors and SMEs, this is more than sufficient in most cases. Those with complex ERP requirements are better served by bexio or another solution.

4. Product development: fast-paced momentum vs. pending modernisation

nextesy was founded in September 2023 and is 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 sits at the core of everything, and all features are interconnected with it. The focus is on the continuous rollout of new features in close collaboration with customers. As a rule, new features are released every two weeks.

bexio was founded in 2013 and has been 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 stage over this time. Viewed from the outside, its strategic focus today lies on marketplace extensions.

What this means: bexio is stable and proven. nextesy is more agile and considerably closer to modern AI standards. If you prioritise recency and automation, you are better off with nextesy. If you value reliability and an established ecosystem with numerous integrations, you will find that in bexio.

5. Price-performance: direct comparison

As of 1 March 2026, bexio renamed its plans and increased its prices. The entry-level package went up by around 16% compared to the earlier Starter price.

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

Actual costs with bexio: The entry-level plan sounds affordable, but quickly becomes confusing and is very limited. Bank feeds are only included from the Advanced plan upwards. Payroll accounting comes as a separate add-on module tiered by headcount. Time tracking is only available from Optima onwards. Depending on your needs, add-on modules add up quickly, requiring careful attention to keep track of the effective overall costs.

nextesy offers bank feeds and payroll accounting for SMEs starting from just CHF 29/month in the Plus plan. Additional costs only arise for payroll employees that exceed the number included in the plan (from 2 employees in the SME plan, from 4 in the Pro plan). These are the only variable costs that may be added.

6. Integrations: bexio provides breadth, nextesy builds natively

bexio is the clear market leader here. More than 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 interface is firmly established. That is a real advantage for growing SMEs with complex workflows.

nextesy is newer and has fewer third-party integrations, but directly covers many functions of external integrations within the product itself. The Zefix integration in the CRM is a handy Swiss-specific feature. For the vast majority of small businesses and self-employed professionals, nextesy's range of integrations is more than adequate in daily practice.

Who does this matter for? Anyone who relies on specific third-party systems—such as an online shop, a POS system, or a specialised industry tool—should look closely at the bexio Marketplace. The fundamental integrations provided by bexio have already been built directly into the system by nextesy. If you are not tied to a specific integration provider and simply need the underlying functionality, nextesy will serve you better thanks to its uniform design and seamlessly connected features. 

Both providers cater to key Swiss requirements: QR-bill, VAT, and invoicing in CHF.

7. Support and fiduciary compatibility

As the market leader with over 100,000 customers according to its own figures (as of 2025), bexio maintains a substantial support operation. At the same time, its Capterra rating of 2.2 out of 5 stars for support (as of 2026) shows that scale does not automatically translate into better assistance. Users report difficulties when cancelling subscriptions and limited availability during day-to-day operations.

nextesy is significantly smaller with around 40 employees. This allows for direct contact and fast response times; anyone calling nextesy support typically waits less than 30 seconds on the line before speaking to someone. The company is led by five co-founders covering finance, sales, AI, accounting, and engineering. The team is backed by advisors from the ETH AI Center, HSG, Innosuisse, and LMU Munich.

For fiduciaries: bexio has been the established standard among Swiss fiduciaries for years. However, as time goes on, bexio is increasingly unable to keep pace with evolving needs—above all, the demand for greater efficiency. The lack of or sluggish product development forces fiduciaries to evaluate other solutions more closely. 

nextesy was initially developed for the fiduciary industry before expanding its focus to SMEs. Thanks to close collaboration with fiduciary partners, nextesy is well on its way to setting the new benchmark for the sector. Its dedicated module for fiduciary professionals offers client mandate management, real-time collaboration, and further practical tools.

8. Conclusion: which software is right for you?

The choice between nextesy and bexio comes down to your priorities.

nextesy is the right choice if you:

• Are self-employed or run a small team of up to 25 employees

Switching from bexio to nextesy is straightforward. For sole proprietorships, it takes about half a working day. Simply export receipts and data prior to cancellation, keeping the statutory 10-year retention requirement in mind. Anyone switching to nextesy from another product benefits from the switch tariff: nextesy costs only CHF 1.- per month until your notice period with the previous provider expires.
