How is Slipstrim different from FreshBooks, QuickBooks, or HubSpot?

Slipstrim is an AI-first operations platform, not an accounting or sales platform. Key differences from FreshBooks and QuickBooks: (1) AI agents and AI assistant built into the platform; (2) AI line-item extraction from plain text in under 30 seconds; (3) native SEPA EPC QR code support for the European market; (4) built-in stock management, travel orders, and CRM that accounting tools don't include; (5) lower price starting at €12/month; (6) designed for day-to-day business operations, not annual tax filing. Unlike HubSpot, Slipstrim's CRM is tied directly to invoices and payments — not sales pipelines.

Frequently Asked Questions

What is Slipstrim?: Slipstrim is an all-in-one AI business platform for freelancers, agencies, and small businesses. It combines invoicing, proforma invoices, CRM, stock management, travel orders, AI business agents, an AI assistant, revenue analytics, automated payment reminders, SEPA EPC QR payments, calendar, and bank integration — all in a single web application. It replaces the need for separate invoicing, CRM, and analytics tools.
How does AI invoice generation work?: Slipstrim's AI invoice generator reads a plain-text description of your project and automatically extracts service names, quantities, units, and prices into clean invoice line items. For example, type "website redesign 40 hours at €120, plus monthly hosting €200" and the AI creates two properly formatted line items instantly. Powered by Google Gemini.
Is Slipstrim suitable for freelancers?: Yes. Slipstrim was built specifically for freelancers and solo operators. The Starter plan (€12/month) covers 50 invoices per month, 10 clients, PDF export, SEPA QR payments, and proforma invoices — everything a freelancer needs without paying for features designed for large accounting teams.
What is an EPC QR code on an invoice and how does it work?: An EPC QR code (also called a SEPA QR code) is a standardised QR code on a European invoice that encodes the payee's IBAN, SWIFT/BIC, invoice amount, and reference number. When a client scans it with any EU banking app, all payment details are pre-filled automatically — eliminating manual entry errors and speeding up payment. Slipstrim generates a compliant EPC QR code on every invoice when you add your IBAN in Settings.
How do automated payment reminders work?: On the Professional plan, Slipstrim automatically sends payment reminder emails before and after invoice due dates, overdue notices for unpaid invoices, and paid confirmation receipts when payment is received. Reminders are fully customisable — no external tool like Mailchimp is needed.
Does Slipstrim have a built-in CRM?: Yes. Slipstrim includes a full built-in CRM. Each client has a profile with contact details, revenue history across all invoices, payment behaviour, and timestamped notes. You can track which clients are active, at risk, or overdue — without needing a separate CRM tool like HubSpot or Pipedrive.
Does Slipstrim support stock and inventory management?: Yes. Slipstrim includes stock management with SKU-level tracking. You can manage inventory quantities, link stock items to invoice line items, and track stock movements as invoices are created and marked as executed.
What are AI Agents in Slipstrim?: AI Agents in Slipstrim are automated business assistants that can perform tasks on your behalf — such as drafting invoices, sending reminders, analysing revenue trends, and answering business questions in natural language. The AI Assistant lets you ask questions like "Who is my top client this month?" or "Are any invoices overdue?" and get instant, data-backed answers from your own business data.
Can Slipstrim manage travel orders?: Yes. Slipstrim includes a Travel Orders module (available on the Professional plan) for creating and managing business travel documentation — useful for agencies and companies that need to issue travel orders for employees or contractors.
Does Slipstrim integrate with banks?: Yes. Slipstrim integrates with Wise (formerly TransferWise) via OAuth, allowing you to connect your Wise account for payment tracking and bank reconciliation. SEPA EPC QR codes on invoices also enable direct bank-app payments without manual IBAN entry.
Is the 14-day trial really free?: Yes. No credit card required. You get full Professional plan access for 14 days — then choose a plan or cancel. No charges until you upgrade.
Can I mix different units in one invoice?: Yes. Each line item has its own unit. Mix m², hours, kg, pcs, lots, and any custom unit in the same document — ideal for agencies billing both time and materials on a single invoice.
Can I cancel my subscription anytime?: Yes. Cancel from Settings at any time with no penalty. Your access continues until the end of the current billing period.
