Choosing well
Compare plans and trials
Look for a free plan when you want to start without a subscription. A free trial can help you check the workflow before paying.
Billit shows a free plan, a 15-day trial and annual-billing prices starting at €6.90 per month, while B2Brouter shows a free plan.
Check formats and compliance
Invoice format support affects whether a service fits your customers and tax process. For Italy, Aruba Fatturazione Elettronica lists XML as its electronic-invoice format.
Compare compliance regions and network support alongside formats, especially when invoices cross borders.
Review invoice limits
Check the invoice limit attached to a plan before moving regular billing into the service. Limits can affect the plan you need as volume changes.
Match ERP and API needs
ERP integrations can reduce manual entry between invoicing and accounting systems. API access matters when another system should send or receive invoice data.
ecosio lists API and web platforms. Check the integration and API details for the systems you already use.
Choose the right platform
Compare the listed platforms before signing up. Products here may be available through web, API, iOS, Android, macOS or Windows.
If you work from a Xiaomi, Redmi or POCO phone, confirm Android support in the product details rather than assuming a web listing includes an Android app.
