Connecting your bank or credit card accounts to QuickBooks is the most seamless way to automatically pull in and categorize transactions into QuickBooks. However, if this option is not available, you can manually upload historical bank transactions into the platform by exporting them in a supported file format such as .CSV, .QFX, .QBO, .OFX, or .TXT file, and then uploading the statement into QuickBooks. There are three approaches to convert PDF bank statements to QBO: manually reformatting bank statements, using PDF to QBO converters, and converting PDF statements into QBO format using Nanonets, a software that automates specific steps in this conversion workflow with minimal effort required for validation and import.
