Why Square Customers Don't Import Directly to QuickBooks

The Field Mapping Problem

Square exports customer data with different field names and formats than QuickBooks expects. Square uses "Customer Name" while QuickBooks needs separate "First Name" and "Last Name" fields. Without conversion, customer records fail to import or create incomplete profiles with missing contact information and addresses.

What This Tool Does

We transform Square customer data into QuickBooks-compatible format: - Names split into First/Last Name fields - Addresses mapped to billing and shipping fields - Lifetime value data preserved in customer notes - Country codes expanded (US → United States) Your QuickBooks customer list matches your Square directory exactly.

Frequently Asked Questions

It depends on your needs. Synder is built for businesses that need advanced automation and accounting integrations. If you're a small business doing monthly imports or occasional conversions, SpreadsheetBroccoli's simpler approach may be a better fit - no subscriptions, no setup, just results.
Not for the same transactions - you'd risk double-counting. However, you could use Synder for ongoing automation and SpreadsheetBroccoli for one-off historical imports or quick ad-hoc conversions outside your normal workflow.
Synder typically requires 30-60 minutes of initial setup (account creation, API connections, mapping configuration), then runs automatically. SpreadsheetBroccoli takes under 2 minutes per conversion - upload, preview, download. Choose based on whether you need ongoing automation or quick occasional conversions.
Pick a clean cutoff date (end of month works best). Let Synder finish processing that period, then disconnect. Export your data from the source platform and use SpreadsheetBroccoli for conversions going forward. The first month needs careful reconciliation to ensure no gaps or duplicates.
Both produce accurate results when used correctly. Synder uses API connections for automated data sync. SpreadsheetBroccoli processes the exact file you provide and shows you a preview before finalizing. Our pre-upload validation catches errors before they reach your accounting software.
Synder typically charges monthly subscriptions regardless of usage. SpreadsheetBroccoli offers flexible options: free preview before commitment, pay-per-conversion, credit bundles for volume, or subscriptions for heavy users. You only pay for what you actually use.
Synder offers various support tiers depending on your plan. SpreadsheetBroccoli provides fast email support to all users. Our file-based approach also means simpler troubleshooting - if something looks wrong, you can see exactly what data was converted in the preview.
Synder processes data on their servers via API connections. SpreadsheetBroccoli processes files entirely in your browser - your data never leaves your device. There's no account to hack, no API tokens to secure, and no data stored on external servers.
SpreadsheetBroccoli is ideal for small businesses doing their own bookkeeping, occasional users who need monthly or quarterly imports, and anyone who wants instant results without learning a new platform. Synder is better suited for larger operations with dedicated bookkeepers who need ongoing automation.
Synder offers automated syncing, real-time connections, and features like multi-channel consolidation or advanced accounting automation. SpreadsheetBroccoli focuses on doing file conversion exceptionally well - fast, private, and simple. We're not trying to replace full accounting platforms, just make conversions effortless.
Absolutely not. This is a major security advantage of SpreadsheetBroccoli over Synder. Synder requires you to hand over API keys or login credentials, creating a permanent security vulnerability. We only touch the specific file you upload, process it in your browser, and forget it immediately.
It works until it breaks. Automated integrations often fail silently when platforms update their APIs, leaving you with weeks of missing or duplicated data to clean up manually. SpreadsheetBroccoli is deterministic: you verify the file right now, import it right now, and you know it's done correctly. It turns "background anxiety" into "finished work."
You can, but the cost is validation and edge cases. AI often hallucinates math or format structures, and free scripts rarely handle messy real-world data (missing SKUs, strange currency formats, tax anomalies). We have battle-tested validators specifically for Synder exports that catch issues a generic script will miss.
