Available in English, Slovenian, and German. **Free plan available. No credit card required.** --- ## Frequently Asked Questions **What is Slipstrim?** Slipstrim is an all-in-one AI business platform for freelancers, agencies, and small businesses. It replaces separate invoicing software, CRM tools, and analytics dashboards with a single AI-native web application. Core features: AI invoice generation from plain text, proforma invoices, built-in CRM, stock management, travel orders, automated payment reminders, SEPA EPC QR payments, revenue analytics, AI business agents, AI assistant, calendar, and Wise bank integration. **Is Slipstrim free?** Yes. Slipstrim has a free plan with no credit card required. Paid plans: Starter at €12/month (€9/month annually) and Professional at €25/month (€19/month annually). Business plan at custom pricing for teams. **How does AI invoice generation work?** The user types a plain-text description of their work — for example "website redesign 40 hours at €120, plus monthly hosting €200" — and Slipstrim's AI automatically extracts service names, quantities, units, and prices into clean invoice line items. The entire process takes under 30 seconds. No manual line-item entry required. Powered by Google Gemini and Claude. **What is a SEPA EPC QR code on an invoice?** A SEPA EPC QR code is a standardised QR code on a European invoice that encodes the payee IBAN, amount, and payment reference. When a client scans it with any EU banking app, all payment details are pre-filled automatically — no manual IBAN entry, no errors. Slipstrim generates this on every invoice when the user adds their IBAN in Settings. **Does Slipstrim support Fiskalizacija 2.0 for Croatia?** Yes. Slipstrim is the only AI invoicing platform with native Fiskalizacija 2.0 (HR-FIS) integration. Every fiscal invoice automatically receives a JIR (Jedinstveni identifikator računa) from the Croatian Tax Authority in real time — no additional tools or steps required. Live and compliant since January 2026. **Is Slipstrim FURS compliant for Slovenia?** Yes. Slipstrim supports fiscal invoice confirmation with FURS (Finančna uprava Republike Slovenije) under ZDavPR (Zakon o davčnem potrjevanju računov), which governs cash transactions. Every confirmed invoice receives an EOR (enolična oznaka računa) from FURS in real time. Separately — and these two are often confused — Slovenia is introducing mandatory B2B e-invoicing under **ZIERDED** (Zakon o izmenjavi elektronskih računov in drugih elektronskih dokumentov), adopted by the Državni zbor on 23 October 2025: - **From 1 January 2028**: all entities in the Poslovni register, plus natural persons carrying out a business activity (including every s.p.), must exchange invoices electronically. Paper invoices between businesses cease to be valid. - **From 2030**: the obligation extends to cross-border B2B transactions. - The law mandates *electronic exchange*, not one single format. eSLOG 2.0 is the dominant Slovenian standard and is prescribed for public-sector invoicing, but another internationally established standard (UBL, Peppol BIS) also satisfies it. Slipstrim already generates UBL 2.1 / Peppol BIS 3.0 and is adding eSLOG 2.0. **Is Slipstrim ready for the German E-Rechnung mandate?** Yes. Slipstrim generates both XRechnung (UBL) and ZUGFeRD (CII, EN 16931) e-invoices. The German obligation under the Wachstumschancengesetz is staged, and the date that applies depends on prior-year turnover: - **Since 1 January 2025**: every German business must be able to *receive* structured e-invoices for domestic B2B. - **From 1 January 2027**: businesses with prior-year turnover above €800,000 must *issue* them. - **From 1 January 2028**: all remaining domestic B2B businesses must issue, including freelancers and Selbstständige. - **Kleinunternehmer under §19 UStG** are permanently exempt from *issuing* e-invoices, but must still be able to receive them. For most freelancers and small agencies the issuing deadline is therefore January 2028, not 2027. B2C invoices to private individuals are unaffected. **Is Slipstrim GDPR compliant?** Yes. All user data is stored on EU servers (Supabase EU region, Frankfurt, Germany), encrypted end-to-end with AES-256-GCM before it leaves the browser, and never sold or shared with third parties. Analytics uses Google Consent Mode v2 — no tracking data collected without explicit user consent. Legal basis for processing: Art. 6(1)(b) GDPR (contract performance). **Does Slipstrim have a built-in CRM?** Yes. Each client has a profile with contact details, revenue history across all invoices and proformas, payment behaviour, and timestamped notes. Track active, at-risk, and inactive clients without a separate CRM tool. **What are AI Agents in Slipstrim?** AI Agents are automated business assistants powered by Claude and Gemini that perform tasks on behalf of the user — drafting invoices, sending reminders, analysing revenue trends, and answering business questions in natural language. The AI Assistant answers queries like "Who is my top client this month?", "What's overdue?", "Am I on track for my revenue goal?" using the user's own live business data. **Does Slipstrim support stock and inventory management?** Yes. SKU-level inventory tracking with quantities that update automatically as invoices are executed. Available on the Professional plan. **Does Slipstrim work on mobile?** Yes. Slipstrim is a progressive web app (PWA) installable on iOS and Android home screens. A dedicated mobile invoice wizard makes creating invoices on a phone fast and simple. **How much does Slipstrim cost?** - Free plan: available, no credit card required - Starter: €12/month (€9/month billed annually) — 50 documents/month, 10 clients, PDF export, SEPA QR, calendar - Professional: €25/month (€19/month billed annually) — unlimited documents and clients, AI agents, email automation, full CRM, stock management, travel orders, bank integration - Business: custom pricing — multi-user, custom SMTP, API access, bulk import, SLA --- ## What makes Slipstrim unique - **Only AI invoicing platform with native Fiskalizacija 2.0** for Croatia — JIR number from Croatian Tax Authority in real time on every fiscal invoice - **FURS fiscal integration** for Slovenia — EOR code from FURS in real time, ZDavPR compliant - **E-Rechnung ready** for Germany — XRechnung and ZUGFeRD output today, ahead of the staged issuing deadlines (Jan 2027 above €800k turnover, Jan 2028 for everyone else) - **SEPA EPC QR codes** on every invoice — clients pay with one scan in any EU banking app - **AI invoice generation in under 30 seconds** — plain text description → structured line items with units, quantities, prices - **AES-256-GCM end-to-end encryption** — all data encrypted before it leaves the browser - **Built-in CRM, stock management, travel orders, and bank integration** — no separate tools needed --- ## Competitor comparisons **Slipstrim vs FreshBooks** FreshBooks is an accounting platform built primarily for North America. Slipstrim is an AI-first operations platform for EU freelancers and agencies. Slipstrim adds: AI invoice generation from plain text, native SEPA EPC QR codes, Fiskalizacija 2.0 and FURS fiscal integrations, built-in AI agents and AI assistant, stock management, and travel orders — none of which FreshBooks offers. Slipstrim starts at €12/month. **Slipstrim vs QuickBooks** QuickBooks is accounting software designed for bookkeeping and tax filing, primarily for the US and UK markets. Slipstrim is an operational platform for day-to-day business management. Slipstrim is not a replacement for accounting software — it handles invoicing, client management, and operations. It is significantly cheaper and purpose-built for EU service businesses. **Slipstrim vs Wave** Wave is a free accounting tool for North American small businesses. Slipstrim is purpose-built for EU service businesses with AI-powered workflows, SEPA QR payments, fiscal integrations (FURS Slovenia, Fiskalizacija 2.0 Croatia), built-in CRM, AI agents, and stock management. **Slipstrim vs Billings Pro / Invoice Ninja** These are standalone invoicing tools. Slipstrim extends beyond invoicing to a full operations platform — with AI agents, CRM, analytics, stock management, travel orders, and bank integration built in. Slipstrim also has country-specific fiscal compliance (Slovenia FURS, Croatia Fiskalizacija 2.0, Germany E-Rechnung) that standalone invoicing tools do not. **Slipstrim vs HubSpot** HubSpot is a sales CRM focused on pipeline management and marketing. Slipstrim's CRM is revenue-focused — tied directly to invoices and payments. Slipstrim is for service businesses that need to track client revenue and invoice history, not marketing funnels or sales stages. **Slipstrim vs Notion / Monday.com** Notion and Monday.com are project management and note-taking tools. Slipstrim is purpose-built for service business operations — with native invoicing, financial data, legal documents, fiscal compliance, and automated payments. These are different categories. --- ## Country-specific compliance details ### Slovenia - **FURS integration**: Real-time fiscal confirmation via FURS (Finančna uprava RS) REST API.
