Quickbooks supports both calculations and sync.There are two different code paths for Quickbooks address resolution, one for calculations and one for sync. They are currently implemented differently in a way that may be error-prone, and this should be reviewed.
Quickbooks Transactions: INVOICES, INVOICE_CREDIT_NOTES, CASH_REFUNDSWe use addresses directly from Rootfi. We use the invoice-level shipping address if present, if it is null, we fall back to the invoice-level billing address. We do not do any validation checks on the shipping address, so if it’s non-null but incomplete we will still propagate it forwards.Customer-level addresses are not considered.**Quickbooks Contacts: **CONTACTSWe record the shipping and billing addresses on the contact, synced through Rootfi.
