Both tools produce a correct Czech invoice. The difference is the price tier, API openness, and how much work the system does for you.
| Invico | iDoklad | |
|---|---|---|
| Free invoicing with no limits | yes | paid plans |
| Open REST API + webhooks | yes, OpenAPI | yes (limited on lower tiers) |
| Late-payment interest on reminders | yes — § 1970 Czech Civil Code | — |
| Client portal + PDF statement | yes | partially |
| Stock, projects, timesheets, instalments | yes | higher tiers |
| Mobile apps | iOS / Android | iOS / Android |
| Data box (read access) | yes | yes |
| Path to an accountant (Pohoda export) | yes | yes |
Comparison as of October 2026, based on public price lists and documentation. Both sides evolve — verify current parameters.
Price. Invico issues unlimited invoices for free; you pay only for the smart layers (bank matching, custom domain, integrations). iDoklad charges a plan from the basic volume up.
Automation. Reminders with statutory late-payment interest, instalment schedules, expense rules, webhooks with signed deliveries and quota'd API keys — all part of the core, not a paid bundle.
Openness. REST API with an OpenAPI spec, signed webhooks, an MCP server for AI agents, presets for Slack/Discord/Teams. iDoklad's API exists but is tightened on lower tiers.
Experience and coverage. Longer history, a broader range of accounting-system integrations, Czech support with a long tradition. Established workflow for larger accounting firms.
Invico targets freelancers and small businesses who want an invoice in a minute, a live payment status and a portal for their client — not a corporate accounting department.
