Nothing is written into your ERP without your say-so
The most reasonable objection to an accounting connection is this: software is going to write into my ledger — what if it writes the wrong thing? That is why reading and writing are separated on the Logo connection. Read operations such as testing the connection, listing products and checking document status work as soon as you connect; operations that write invoices, contacts or orders are enabled for your account separately.
We built the order that way because undoing a wrong record in an ERP costs far more than never writing it. You connect first, look at the screens, watch the flow — and only then turn writing on.
