American Express + NetSuite Integration

The American Express integration automates corporate card transaction feeds into NetSuite. Charges flow in daily with pre-coded GL accounts and departments, eliminating the monthly grind of manually reconciling Amex statements against your general ledger.

Corporate Card Statements Shouldn't Take a Week to Process

If your company issues American Express corporate cards, you're familiar with the monthly reconciliation grind. Statements arrive, someone downloads a CSV or PDF, and then your accounting team manually matches each charge to a GL account, department, and vendor. For companies with 20+ cardholders, this easily eats a full week of someone's month.

The integration automates the data feed. Amex transactions flow into NetSuite daily, pre-coded where possible, with receipts and memos attached by the cardholder through Amex's expense management tools.

What We Build

Daily Transaction Feed: American Express provides transaction data through their commercial data feed (the @ Work platform or direct file delivery). We configure NetSuite to ingest these transactions daily, creating credit card charge records or expense report lines tied to the correct cardholder and corporate card account.

Auto-Categorization Rules: Based on merchant category codes (MCCs) and vendor patterns, we build rules that automatically assign GL accounts. Office supplies from Staples always hit the office supplies account. Airline charges always hit the travel account. Your team only needs to review exceptions and edge cases.

Cardholder Assignment: Each Amex card maps to a NetSuite employee record. Transactions from card ending in 4321 always land under Sarah's expense report. When Sarah's card gets replaced, we update the mapping once and everything continues working.

Statement Reconciliation: Monthly Amex statements reconcile against the transactions already posted in NetSuite. The integration flags discrepancies -- missing transactions, duplicate charges, or amount mismatches -- so your team can investigate instead of manually comparing spreadsheets.

Multi-Card Programs: We handle Amex corporate cards, purchasing cards (P-cards), and virtual cards. Each card type can have different GL treatment and approval workflows. P-cards might post directly as expenses while corporate cards require employee submission and approval.

Technical Approach: The connection method depends on your Amex setup. Some companies use Amex's @ Work Connect for automated file delivery (typically daily flat files in a standard format). Others pull data through Amex's API for Business. On the NetSuite side, we use either a SuiteScript-based importer or middleware to parse and create transactions. The file-based approach is simpler and more reliable; the API approach offers more real-time data.

Key Benefits

• Eliminate manual statement entry. Transactions arrive in NetSuite automatically, not through spreadsheet imports.
• Faster month-end close. Card reconciliation drops from days to hours.
• Consistent coding. Auto-categorization rules enforce your chart of accounts without relying on cardholder memory.
• Better spend visibility. See card spending in NetSuite dashboards throughout the month instead of waiting for statement close.
• Receipt compliance. Cardholders attach receipts through Amex's tools, and they flow to the NetSuite transaction record.

Is This Right for You?

Automating the Amex-NetSuite feed makes sense for any company with 10+ corporate cardholders. The time savings on monthly reconciliation alone justify the setup cost within a few months.

If you have just a few cards, the manual process is manageable. But consider the integration early -- the setup is straightforward and the ongoing benefit compounds as you add more cardholders.
