hice.ai vs BigTime: which PSA should you pick in 2026

    An AI-native PSA built for the European market versus a popular US time tracking and invoicing tool loved by small accounting and architecture firms.

    Verdict

    BigTime is a fine pick for a small US accounting or architecture firm that wants integrated time tracking, project management and QuickBooks-friendly invoicing for 5 to 30 people. But for a European consulting boutique with 20 to 200 people, BigTime quickly hits walls: English-only UI, US-only tax logic, no real conversational AI, and design patterns that feel a decade old. hice.ai starts from the opposite premise: AI-native, four native languages, billing data ready for European tax rules (VAT, reverse charge) with export to accounting tools, and per-active-Manager pricing that usually comes in below BigTime's 15 to 40 dollar per user per month list price.

    The SMB PSA category and where BigTime sits

    BigTime was founded in 2002 as a time tracking tool for US professional services firms: accountants, architects, engineers, small IT shops. After FOX Software acquired it in 2022 and PE ownership took over, the product kept its DNA: easy to set up, deeply integrated with QuickBooks Online and Desktop, focused on billable hours and invoicing.

    That makes it a perfectly reasonable tool for a 5 to 30 person firm that wants to stop running timesheets in Excel. But a modern PSA is not just timesheets plus invoices: it is the integration of resource planning, capacity, margin, CRM, internal knowledge and now an AI layer that turns all of that into a conversation. On those axes BigTime trails behind.

    Total annual cost: per user versus per active Manager

    BigTime list: Essentials around 15 dollars per user per month, Advanced 35, Premier 45, Projector (their resource planning module) 60 plus. An Italian or French boutique with 40 consultants on Advanced pays roughly 16,800 dollars per year in licenses alone, plus setup, training and the QuickBooks integration that mostly does not apply in Europe.

    hice.ai works differently: you pay only active Managers, the people who actually run projects, resources or accounts each month. In a 40 person firm that is typically 8 to 12 active Managers. Annual cost falls below BigTime Advanced while including conversational AI, EU-ready billing data, GDPR and four native languages, with no module surcharges.

    AI-native versus traditional time and billing

    BigTime has shipped some AI features in 2024 and 2025: timesheet description suggestions, approval pattern detection, basic workflow automation. They are bolt-on features layered on top of an architecture built for data entry.

    hice.ai is different at the foundation: chat is the operating system. Ask 'how did the Rossi account margin land in March' and you get the answer, the chart and the next action in the same conversation. For a PMO or partner this changes the day: ten dashboards become ten questions. SMB teams often benefit more from this paradigm than enterprises, because they do not have an analyst building reports for them.

    The European market gap

    BigTime was born in the US. The UI is English only, billing follows American logic (sales tax, no structured VAT, no real intra-EU reverse charge), there is no integration with the Italian Sistema di Interscambio, no Factur-X output for France, no AEAT for Spain. GDPR is claimed but data residency is typically US.

    hice.ai starts from Europe: it prepares billing data following Italian, French and Spanish VAT rules (reverse charge, withholding) and exports it to accounting tools and e-invoicing providers, GDPR by design with EU hosting, six languages (IT, EN, ES, FR) in both UI and AI replies. For a European company this is not a minor detail, it is the difference between running your PSA standalone and bolting on three other tools to fill the gaps.

    When BigTime wins and when hice.ai wins

    BigTime wins in specific scenarios: a US accounting or architecture firm of 5 to 30 people, already on QuickBooks, simple USD billing, no multilingual need, linear delivery process. There BigTime is mature, has tons of documentation and an active community.

    hice.ai wins wherever you need European languages, European tax compliance, conversational AI as the primary interface, more sophisticated resource management, multi-country and real multi-currency. If you are an Italian, French or Spanish IT boutique, or a digital agency invoicing across countries, it is not a contest: BigTime forces workarounds, hice.ai is native to that world.

    Which to pick depending on your firm

    Small US accounting or architecture firm with 15 staff

    Already on QuickBooks Desktop, billing in USD, all clients in the States, simple delivery process. BigTime is still the right call: low price, immediate QuickBooks integration, DCAA available if federal contracts come up. hice.ai would be overkill in this scenario.

    Italian IT consulting boutique with 50 consultants

    Mandatory SDI e-invoicing, clients across Italy, France and the UK, team speaking Italian and English, need for 6 month capacity planning and per-client margin analysis. BigTime forces all the tax side out of scope, English UI for everyone, no real AI. hice.ai computes the T&M amounts to bill and hands the accountant or ERP ready-to-use data, in one flow.

    Multi-country digital agency Europe plus LATAM with 80 people

    Offices in Milan, Madrid, Paris, Mexico City, Buenos Aires. Four languages spoken daily, billing in EUR and USD or peso, different tax regimes. BigTime is monolingual and US-centric, it does not fit. hice.ai supports IT, EN, ES, FR natively in UI and AI, handles real multi-currency and adapts to local European rules.

    FAQ

    How long does a BigTime to hice.ai migration take+

    The typical path is 5 to 7 business days. We export your projects, clients, timesheets and invoices from BigTime via API, map them to the hice.ai structure and provision users. The team can start working in chat from day one while history is imported in the background.

    Can I issue Italian SDI e-invoices from BigTime+

    Not natively. BigTime is not connected to the Italian Sistema di Interscambio: you would have to export invoices, reformat them as XML and upload them through a third party intermediary. hice.ai does not issue the invoice: it computes the T&M amounts to bill and prepares data ready for your accounting tool or SDI intermediary (TeamSystem, Zucchetti, Fatture in Cloud), which handles issuance and archival.

    Does French Factur-X work on BigTime+

    No. Factur-X requires a PDF/A-3 with embedded XML compliant with the French 2026 standard: BigTime does not produce it. hice.ai prepares the billing data for French customers ready for accredited PDP platforms, which issue and transmit the document.

    Does BigTime integrate with Spanish AEAT for Verifactu+

    No, there is no native AEAT support nor Spanish SII compliance. hice.ai prepares Spanish billing data following VAT and regional rules and exports it to accounting tools compliant with Verifactu, which issue the document.

    What changes between QuickBooks and Italian or European accounting+

    QuickBooks runs on US sales tax logic: it does not handle structured VAT, intra-EU reverse charge, withholding tax, ten year archival or periodic filings. In Europe you need a different accounting integration. hice.ai connects with Italian ERPs (TeamSystem, Zucchetti, Fatture in Cloud) and French and Spanish accounting platforms.

    How does per-active-Manager pricing compare to BigTime per-user pricing+

    BigTime bills every user with access, even people who only enter timesheets or read a report once a month. hice.ai charges only active Managers, typically 20 to 30 percent of the team. For a 40 person firm that is 8 to 12 seats instead of 40, and total annual cost lands below BigTime Advanced even with AI included.

    Is the mobile app on par+

    BigTime has a mature mobile app for timesheets, expenses and approvals. hice.ai takes a different angle: the AI chat works on mobile and desktop the same way, so any team action goes through one interface. Logging hours or approving an expense is just a chat message or a voice note.

    Which languages does customer support cover+

    BigTime supports customers in English during US hours. hice.ai supports Italian, English, Spanish and French during European business hours, with native language SLAs on business plans. For a European company this is a tangible difference.
