Boxflow vs Comax eBox: which one fits you?
Both solutions automatically retrieve your eBox Enterprise and MyMinfin documents. They start from a different philosophy, though: Comax is a complete document management suite installed on your own servers, Boxflow is a focused, fully managed cloud service.
Boxflow
Focused on eBox and MyMinfin: self-service set-up, fully managed, transparent pricing.
Comax
Complete document management suite with an eBox/MyMinfin module, installed on your own servers.
Choose Comax if you want a complete, more complex document management solution with an eBox/MyMinfin module, running on your own servers. Choose Boxflow if you want a solution that focuses specifically on eBox and MyMinfin: easy self-service set-up, fully managed without a local server, transparent pricing and open integrations.
Comparison at a glance
| Boxflow | Comax | |
|---|---|---|
| Pricing model | Public pricing from €0: free plan for 1 company, cancel monthly, discount for annual billing. | On quote only. Comax eBox and Comax MyMinfin are separate, paid modules on top of the suite and the server installation. |
| Hosting | Fully managed cloud (SaaS), data within the EU. No server to maintain. | Installation on your own servers; you manage hosting, back-ups and updates yourself. |
| Set-up | Self-service through a wizard; live within minutes with one last eID or itsme login per company. | On-premise installation by Comax; demo and quote on request. |
| Forwarding | Automations on sender, company, message type, subject and more; email, assignment to user or team, statuses, webhooks. | Indicate once, per document type and per company, which email addresses documents are sent to. |
| Integrations | Open REST API, webhooks and an official Make app: connect to thousands of tools (SharePoint, OneDrive, Google Drive, Teams, your ERP …). | Own integrations with a specific set of software vendors; no publicly documented API. |
| Breadth of offering | Does one thing very well: government mail (eBox Enterprise and MyMinfin). | eBox and MyMinfin are modules within a broader document management suite. |
| Return on investment | Start for free, live within minutes, no implementation project or server costs. | Custom investment plus server and maintenance costs; pays off most if you also use the other Comax modules. |
