What Our Users Say
works good, wish it had batch mode
I was spending 4-5 hours every month reformatting exports manually. This tool paid for itself in the first use. The preview feature helped me verify the mapping before paying.
exactly what i needed thx!!
Super straightforward. Upload, convert, download. No account needed which is nice. Would give 5 stars if they add Xero support.
saved me hours of work
My accountant was so happy when I sent her the converted file. No more back-and-forth about date formats or missing columns. Everything imported correctly on first try.
fast and easy 10/10 would recommend
Been using this for 6 months for monthly reconciliations. Handles all the edge cases - partial refunds, multi-line orders, currency conversions. Very reliable tool.
Good tool, does what it says. Interface could be bit better but conversion quality is excellent. Using it for my 3 Shopify stores.
Switched from A2X to this. Way simpler for my needs - I don't need real-time sync, just clean data once a month. This delivers exactly that.
finally!! something that works with QB desktop!!

Why QuickBooks Desktop Requires IIF Format
Desktop vs Online Import
QuickBooks Desktop doesn't support simple CSV imports like QuickBooks Online. Instead, it uses IIF (Intuit Interchange Format), a legacy tab-delimited format with strict syntax requirements. IIF files use special header rows (!TRNS, !SPL, !ENDTRNS) that must be precisely formatted.
IIF Complexity
- !TRNS: Header row with invoice total and customer info
- !SPL: Split lines for each product (negative amounts)
- !ENDTRNS: End marker for each invoice
- Tab-delimited with exact column order
- Amounts: Positive in header, negative in splits
- Strict syntax - errors fail silently

Common IIF File Import Errors
Issues you might encounter when importing Orders Export data to IIF File - and how we solve them
IIF Import Failed Silently
QuickBooks Desktop IIF imports fail silently with format errors

Import in QB Desktop Company > File > Utilities > Import > IIF Files
Customer Must Exist in QuickBooks First
IIF doesn't auto-create customers like QBO
NAME: John Doe (not in customer list)
Create customer in QB Desktop first
Import customer list before importing invoices
Use Lists > Customer:Job List > Add to create customers
Must Import in Single-User Mode
QuickBooks Desktop requires single-user mode for IIF imports
Import attempted in multi-user mode
Close all other QB instances first
File > Switch to Single-User Mode before importing
Lock out other users temporarily for import
Frequently Asked Questions
IIF is a legacy format with complex syntax requirements. The tool must generate precise tab-delimited files with header rows (!TRNS), split rows (!SPL), and end markers (!ENDTRNS). This technical complexity justifies the premium pricing, though it's still far cheaper than monthly subscription plugins.
QuickBooks Desktop requires single-user mode for IIF imports to prevent data conflicts. Before importing, go to File > Switch to Single-User Mode. This locks out other users temporarily. After import completes, switch back to multi-user mode.
Yes! Unlike Xero or QuickBooks Online, QuickBooks Desktop doesn't auto-create customers or items from IIF imports. You must create them first via Lists > Customer:Job List and Lists > Item List, or import customer and item lists separately.
No, there's no automatic undo. IIF imports are permanent. ALWAYS test with a backup company file first. Make a backup before importing: File > Create Backup. If import goes wrong, restore from backup.
IIF format errors often fail without error messages. Common causes: incorrect tab delimiters, mismatched amounts (debits ≠ credits), non-existent customers/items, or missing !ENDTRNS markers. Our tool generates strictly validated IIF to prevent silent failures.
QuickBooks Desktop uses IIF (tab-delimited with special syntax), while QuickBooks Online uses simple CSV. IIF is more complex but works with all Desktop editions. If you have QBO, use our simpler WooCommerce → QuickBooks Online tool instead.
