Integrations & uploads
QuickBooks, Sage Pastel, Excel uploads, and the developer API.
Which systems can I connect, and how do connectors work?Keep invoicing where you already do — connectors capture the invoice, fiscalise it, and write the result back.
How do I connect QuickBooks (Online and Desktop)?Online connects with a secure authorisation and webhook; Desktop connects through the Web Connector file.
How do I connect Sage Pastel?Install the PI Pastel Agent next to your Pastel company; it watches for new invoices and fiscalises them.
How do I fiscalise invoices from an Excel/CSV upload?Fill the PI Fiscal template — one row per line, grouped by document — and upload it.
How do I fiscalise from my own system with the API?Create an API key and POST a normalised invoice to /api/v1/fiscalise with the X-Api-Key header.
