Can I link multiple transactions and documents together?

Sure. On a booking you can have multiple transactions and documents. In fact a booking can consist of

• only one transaction.
• only one document.
• multiple transactions.
• multiple documents.
• one or multiple transactions combined with one or multiple documents.

This way you can combine e.g.

• an invoice, a credit note and a transaction.
• a Paypal receipt with its related invoice.
• an invoice, 2 payment transactions and a refund transaction, in case you would have paid the invoice twice.

You can add your additional transactions or documents to an entry by clicking '+ Add' next to 'Transactions' or 'Documents', depending on what you wish to add to the entry.
