SKULabs has several integrations with QuickBooks Online:
Import QuickBooks listings and link them to catalog items
Import invoices created on QuickBooks as processing orders within SKULabs. The orders must be created within your store's maximum order days settings. This allows you to process and fulfill QuickBooks invoices in SKULabs.
Push stock quantity updates to QuickBooks, which by default is not enabled.
Furthermore, you can configure your accounting settings to choose the data you want to sync to QuickBooks Online:
Push Sales Receipts and/or Invoices for orders created within the last 30 days from SKULabs to QuickBooks. Note: Don't forget to set up sales tax support in QuickBooks and set up shipping charge support in QuickBooks.
Push purchase orders from SKULabs to QuickBooks:
Processing purchase orders created on SKULabs within the last 120 days.
Received purchase orders closed on SKULabs within the last 120 days to QuickBooks
Backdated product creation for Purchase Order, Sales Receipt and Invoice sync.
Product SKUs are required to exist on QuickBooks before they can be included on Purchase Orders, Sales Receipts, or Invoices. If a product SKU does not exist on QuickBooks, SKULabs will be required to create the product in QuickBooks automatically and backdate it to allow inclusion.
Products are created with no current on hand quantity to prevent backfilling transactions during creation. If you wish to create new products with the most recent on-hand value in SKULabs, we recommend enabling stock sync to allow SKULabs to add inventory for these newly created 0 on-hand products.
Multiple QuickBooks accounts
Inbound order and listing sync from multiple QuickBooks accounts into SKULabs is supported.
Outbound sync to multiple QuickBooks accounts is not currently supported. If you have multiple QuickBooks company accounts, each account should be treated separately and connected individually to SKULabs.
