FAQ
Frequently asked questions
Management software brings a business's admin tasks together in one tool: invoicing, customer tracking (CRM), cash flow, sales. It replaces spreadsheets and separate apps with a single interface.
Without management software, most entrepreneurs juggle several tools (invoicing, banking, CRM, online store) and waste time re-entering the same information. Management software centralizes these tasks, saves time, and reduces errors.
Klark is an all-in-one management platform for entrepreneurs, freelancers and small businesses. It centralizes banking aggregation, CRM, invoicing, e-commerce and several SaaS tools in a single interface, available on web, iOS and Android.
Klark is built for active small and mid-sized businesses, online sellers and independents who want to manage accounts, clients, sales and invoicing in one place, without juggling multiple apps.
Yes. Klark replaces 5 to 10 separate apps — appointment scheduling, CRM, banking aggregator, invoicing, mobile POS — with a single subscription covering the essential features.
Yes. Klark uses Open Banking aggregation (PSD2) to securely connect your accounts in read-only mode, and integrates with Shopify, Stripe, PayPal and PrestaShop. Your stores keep working as usual while Klark becomes your central dashboard.
Yes. Fakture generates structured electronic invoices aligned with the European EN 16931 standard, which underpins the EU's ViDA reform and the national mandates rolling out across Europe from 2026 (Belgium, France, Germany, Italy, Poland and more). In the US, there is no federal mandate yet, but the same structured format keeps you ahead as e-invoicing spreads.
Yes. Klark provides an MCP (Model Context Protocol) connection compatible with Claude, ChatGPT, Grok, Mistral and Perplexity, to drive your data and tools directly from an AI assistant.
Not yet. Klark is currently in early access with reduced pricing, and a freemium plan is planned for a future release. The monthly subscription can be cancelled at any time, with no commitment.
Yes. Whether you're a sole proprietor, VAT-exempt under a small business threshold, or already VAT-registered as a single-member LLC, Klark adapts to your situation for invoicing, quotes and cash flow tracking.
Klark tracks the status of every invoice (sent, overdue, paid) and lets you prepare overdue payment reminders in one click, including in plain language through your AI assistant.
