Factorial vs Personio: what it costs per year

What Factorial and Personio look like

Pricing: both publish a starting price, neither publishes a total

Factorial's US pricing page says plans start at $8 per user per month, and its German page says €8. The page does not list fixed tiers. Every plan includes Factorial Core with the employee directory, onboarding and offboarding, payslip distribution, bulk document sending, legal e-signatures and fillable PDFs. Four module families are added by quote: time management (time off, time tracking, shift management), talent management (performance, recruitment, engagement, training), finance (project management, expenses, procurement) and IT (SaaS management, IT inventory, multi-OS device management, endpoint security). The page names no minimum term and says subscriptions can be canceled.

Personio's HR plans, Core and Core Pro, start at €7.60 per employee per month for companies with 50 or more employees, according to the vendor's pricing page. Payroll starts at €5, and companies with up to 49 employees get HR and payroll together from €14. Personio's pricing pages, as we checked them in September 2026, also list a 12-month minimum term and a one-time setup fee, and the final price is a quote based on headcount and add-on apps. Core Pro adds items such as multiple legal entities, workforce planning, API access and custom integrations, according to Personio's plan overview.

The units differ. Factorial charges per user and Personio per employee, so a company with many frontline staff who never log in should ask Factorial who counts as a user. The bigger gap is what the starting price leaves out. Factorial's modular design means the first price rarely resembles the final one, and Personio's setup fee and AI credits sit on top of the monthly rate. Ask both vendors for a first-year offer with the same headcount, the same modules and the AI features you plan to switch on.

AI features: Factorial bets on one agent, Personio on AI inside each workflow

Factorial announced its AI agent One in November 2025 at its Factorial Next event in Barcelona. The design has two agents: one represents the company and applies its policies across HR, finance and IT, and the other acts for the individual employee. Factorial's product updates from February 25, 2026 list what One does today: answering policy questions in real time, checking expenses against policies, creating surveys from a single prompt, building reports in plain language ("create a performance report of Q4"), drafting offer letters and contracts from templates, and suggesting shift schedules. One also runs on mobile for all users. The pricing page itself lists AI only as CV parsing in recruiting, so ask whether One is part of your price.

A customer story from the framework vendor Mastra gives a look at how One is built. The agent calls the same GraphQL API as Factorial's own front end, so it inherits the existing permission system instead of keeping a second one, and answers follow the same access rules as the screens. Mastra says the agent is live for all 17,000 customers, with about 70 skills and 500 tools behind it. This is a vendor-adjacent source, so treat the numbers as indicative.

Personio's approach is a set of AI functions inside existing workflows. Its help center describes the Personio Assistant, which answers questions using data the asking user is allowed to see, including profile data, HR documents and analytics, and which admins can connect to third-party tools. It launched in beta in April 2025, and we could not confirm a general-availability date. AI Performance Summaries condense feedback, reviews and notes for managers and are opt-in, and AI summaries exist in analytics. Most AI features need an administrator to switch on general AI access first.

Recruiting is where Personio has put the most recent money. The Talent Screening Agent checks incoming applications against criteria you set and consumes AI credits at a fixed rate per action, and billable use starts only after an administrator accepts it. In April 2026 Personio acquired the Munich AI startup aurio to build out candidate sourcing and screening, and it says 9,000 of its customers use its recruiting function. Factorial lists AI candidate screening and interview scheduling on its AI page. We found no published accuracy figures for either vendor's screening, so run it on past applications before you rely on it.

Data, hosting and AI governance: Frankfurt for both, different AI stacks

Factorial's sub-processor list names Amazon Web Services in Frankfurt for web hosting. For AI, it names Microsoft Azure in Germany and Sweden for recruitment CV processing, performance reviews, report generation and competency suggestions, and Google Gemini in the EU for reading invoices and receipts. Other entries include ClickHouse in Germany, Intercom in Ireland and Typeform in the United States, and Factorial says it relies on Standard Contractual Clauses for international transfers. Factorial's trust center also lists an AI overview document that covers its AI features and training-data practices.

Personio's AI data privacy FAQ says its AI runs on large language models from Anthropic, hosted on AWS Bedrock inside Personio's own EU infrastructure, with data stored in Frankfurt. It states that neither Personio nor any third party uses inputs or outputs for training, and that personal data is not stored by Bedrock or the models. We read this FAQ through a search excerpt because the page blocked our request, so read the original before you quote it in a data protection assessment.

Both set-ups keep AI processing in the EU, which makes a data processing agreement under Art. 28 GDPR easier to review. The practical difference is access. Factorial's trust center shows its ISO certificate, SOC 3 report and ENS certificate publicly, but the SOC 2 Type 2 report, penetration test reports and the platform data processing agreement need an access request that Factorial reviews within 24 business hours and grants for 30 days. Personio's trust center is the entry point for its documents and sub-processor list. Whichever you choose, ask for the AI sub-processors by name, because they change faster than the base hosting.

Scope and payroll: a wide suite against an HR and payroll core

Factorial goes well beyond HR. Besides the modules above it offers expense management, project management, procurement and an IT stack with device management and endpoint security. A company that today pays for a time tracker, an expense tool and a device management product can consolidate them, which is the real price argument for Factorial. The trade-off is that a suite with this many modules needs a clear owner for each one, so decide before you buy which modules you will actually switch on in the first year.

Personio concentrates on HR, recruiting and payroll. Personio says its payroll business serves more than 1,500 customers and grows 80 percent a year, and that 9,000 customers use recruiting. Its payroll page describes in-house payroll for Germany, and public sources do not make clear which other countries Personio processes itself and which run through an integration with a local payroll provider. For Austria and Switzerland we found no native Personio payroll, so check this before you plan a DACH rollout beyond Germany.

Factorial approaches payroll through preparation and integrations. Its German site lists payroll preparation and a DATEV connection, which since June 2025 syncs new hires, personal data changes, bank details, base salary and working hours to DATEV, with terminations, tax data and payroll variables listed as planned. In Spain Factorial connects to payroll tools such as a3nom and Sage200, and in Mexico to Dataia. If you want one system to calculate the payslip, Personio is the closer fit in Germany. If you already work with a payroll bureau or DATEV, Factorial's model is enough.

Security paperwork, languages and track record

Factorial's trust center lists ISO/IEC 27001:2022, SOC 2 Type 2, SOC 3 and ENS RD 311/2022 at the high level, Spain's national security scheme. It states a recovery time objective of 1 hour and a recovery point objective of 1 day, and shows security grades from March 27, 2026 (ImmuniWeb A, MDN Observatory B+, Qualys SSL Labs A+). Personio's trust center lists ISO/IEC 27001 and ISO/IEC 27017. Factorial's trust center does not list ISO/IEC 42001, the standard for AI management systems, and Personio's did not at our September check. Only 6 of the 64 suites in our directory list it, so ask both how they govern their AI.

Personio's interface comes in 18 languages: German, English, Spanish, French, Dutch, Italian, Swedish, Finnish, Polish, Portuguese, Catalan, Croatian, Czech, Danish, Hungarian, Norwegian, Romanian and Turkish. Factorial's help center lists 9 fully supported languages in 12 variants (Catalan, German, UK and US English, Spanish, Latin American Spanish, French, Italian, Dutch, Portuguese for Portugal and Brazil, and Swedish) and Russian, Polish and Turkish in beta. Customer support runs in Portuguese, Spanish, French, German, Italian and Catalan. If you need Finnish, Czech, Danish, Hungarian or Norwegian for employees, only Personio qualifies; in our directory 8 HR suites offer Finnish.

Both companies are large enough that vendor survival is not the question. Personio's 2023 statements, reported by deutsche-startups.de, showed revenue of €144.3 million, up 52 percent, with a loss of about €177 million and an average of 1,710 staff. In 2026 it announced profitability, and on September 10, 2026 it was named a Core Leader in the Fosway 9-Grid for Cloud HR for the second year in a row. Factorial's own pages put its team at about 1,500 people. Its customer figures differ by page: 17,000 or more clients in more than 120 countries on the About page, 17,000 or more companies in over 65 countries on the German site, and 16,000 or more businesses in over 90 countries in the June 2026 funding announcement. Use these as scale indicators, not as audited numbers.

Country fit and compliance: Spain and Latin America against German-speaking Europe

Factorial runs its main offices in Barcelona, Mexico City and São Paulo and calls Germany its top international growth market, with a Munich office announced in June 2026 and expansion planned in France, Italy and Portugal. Our directory lists Factorial as strong in Spain, one of 5 HR suites with that rating, and Factorial vs Sesame HR compares it with its Valencia rival. Personio earned 89 percent of its 2023 revenue in Germany, Austria and Switzerland, and our directory lists it as strong in those three countries, shared with 7 suites that are strong in Germany. For Personio against a UK and US platform, see Personio vs HiBob.

Each home market has its own rule for AI at work. In Spain, Ley 12/2021 added a right for works councils under Article 64.4 d) of the Workers' Statute to be told the parameters, rules and instructions behind algorithms or AI systems that affect decisions on working conditions, access to and keeping of employment, including profiling. In Germany, the works council has a co-determination right over technical systems that can monitor behavior or performance under § 87 Abs. 1 Nr. 6 BetrVG, an information right on planned AI use in work processes under § 90 Abs. 1 Nr. 3, and a say over selection guidelines created with AI under § 95 Abs. 2a. Where co-determination applies, the system generally cannot go live without a works agreement, according to Personalwirtschaft.

Across the EU, AI that filters job applications or evaluates candidates, and AI that monitors and evaluates the performance of workers, is high-risk under Annex III of the AI Act, with obligations applying from December 2, 2027. Both vendors sell AI for recruiting, so ask each for its AI Act documentation before you switch those features on. For a rollout in several countries, plan the works council step per country, because the Spanish information right and the German co-determination right are separate procedures with different timelines.

A two-week test plan that settles the open questions

Both vendors let you see the product before you sign: Personio with a 14-day trial that needs no credit card and comes with sample data, Factorial with a free demo and product tour. Use the time on three tasks you do every week, not on a feature tour. First, set up a leave policy and a shift pattern for one real team and see how many clicks it takes. Second, ask the AI agent five questions from your own handbook and check each answer against the source. Third, export a payroll-ready file for one month and give it to the person who runs payroll.

Then put the commercial questions in writing. Ask for the first-year price with your headcount, the setup fee, the minimum term, what happens to AI credits you do not use, which AI sub-processors apply, and how the vendor will support your works council with documentation. A vendor that answers these before signature is cheaper in practice than one that wins by €0.40 per head.

Who should pick Factorial and who Personio

The bottom line

The starting prices are too close to settle anything. Choose Factorial if you want one vendor for HR, spending and IT, your teams sit in Spain or Latin America, or you need its security reports. Choose Personio if HR and payroll are the whole job, your staff work mainly in German-speaking Europe, or you need a language Factorial does not offer. Whichever you pick, get AI pricing, AI sub-processors and the works council steps in writing before you switch AI on.
