Slipstrim is an all-in-one AI business platform for freelancers, agencies, and small businesses. It combines invoicing, proforma invoices, CRM (client management), stock and inventory management, travel order management, 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 Claude and 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.

Can I create proforma invoices?

Yes. Slipstrim supports both regular invoices and proforma invoices. A proforma invoice is a preliminary bill sent before work is completed or goods are shipped — commonly used for deposits, estimates, or advance payments. You can convert a proforma to a final invoice with one click once the work is done.

Is Slipstrim more than just invoicing software?

Yes. Slipstrim is a complete business management platform. In addition to invoicing, it includes: a built-in CRM for client management; stock and inventory management with SKU tracking; travel order creation and management; AI business agents that automate tasks and answer business questions; a revenue analytics dashboard; a calendar; bank integration via Wise; and automated payment reminders. It is designed to replace multiple separate tools — invoicing software, CRM, analytics, and task automation — with a single, unified platform.

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.

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.

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.

How is Slipstrim different from FreshBooks or QuickBooks?

Slipstrim differs from FreshBooks and QuickBooks in scope and focus. Where FreshBooks and QuickBooks are accounting-first tools, Slipstrim is an AI-first business operations platform. Key differences: (1) AI agents and AI assistant built into the platform; (2) AI line-item extraction from plain text; (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) a modern, fast UI designed for day-to-day business ops rather than annual tax filing.

How long does it take to create an invoice?

Most invoices take under 60 seconds to create in Slipstrim. Select a client, describe your work in plain text, let the AI extract line items, then export to PDF — all in one flow. For repeat clients and recurring work, templates and saved settings speed things up further.

Does Slipstrim export invoices to PDF?

Yes. Every invoice and proforma created in Slipstrim can be exported as a professionally formatted PDF at any time. PDFs include your logo, brand colour, itemised line items, VAT breakdown, totals, payment terms, and SEPA EPC QR code.

What currencies does Slipstrim support?

Slipstrim supports multiple currencies. You can set a default currency in Settings and change it per invoice. Common currencies including EUR, USD, GBP, CHF, and others are supported.

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.

Do you support EPC / SEPA QR payments?

Yes. Add your IBAN and SWIFT/BIC in Settings. A standards-compliant EPC QR code appears on every invoice, scannable by any EU banking app for instant payment.

Can I use my own logo and brand colour?

Yes. Upload your logo and choose any HEX colour in Settings. Both appear on all invoices and throughout the app interface — giving your documents a fully branded, professional look.

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.
