What is Bill.com's invoice CSV import row limit?

Bill.com supports up to 1,000 bills per CSV import file. Invoice exports exceeding this limit must be split into 1,000-row chunks before upload.

Will vendor IDs and invoice numbers be preserved exactly in the output files?

Yes. The tool performs only structural splitting — no cell values, including vendor IDs, invoice numbers, amounts, or dates, are modified in any way.

What if my ERP export includes multi-line invoices spanning multiple rows?

Row count splitting divides at row boundaries regardless of logical invoice groupings. If multi-line invoices must stay together, you should pre-sort and group the export so related rows are contiguous, then set a row limit that does not split mid-invoice.

Does the output preserve the original column order?

Yes. Column order from the source CSV is preserved exactly in every output chunk. No columns are added, removed, or reordered.

Can I use this for vendor credit memo or payment remittance CSVs?

Yes. Any AP-related CSV file — invoices, credit memos, payment remittances, vendor master exports — can be split by row count using this tool.

Split Large Invoice Batch CSVs Into AP Platform–Ready Upload Files

Accounts payable teams exporting invoice batches from ERP systems like SAP, Oracle, or Dynamics face strict upload limits on downstream payment platforms. Tipalti, Bill.com, and similar AP automation tools cap bulk invoice imports at 1,000–5,000 rows per file. When a month-end invoice run produces an export of 20,000 lines, it cannot be loaded without splitting.

AP teams that process high invoice volumes — manufacturing, construction, or multi-entity companies with hundreds of vendors — regularly hit these platform limits at month-end close. The manual workaround is to open the ERP export in Excel and copy-paste rows into separate files, a process that takes 30–45 minutes and introduces risk of dropping the header row or misaligning columns, which causes the entire batch upload to fail.

Deliteful splits your invoice batch CSV into fixed-row chunks in seconds, with the header row preserved in every output file. Payment platforms require the header to map vendor ID, invoice number, amount, and due date columns correctly — a missing header means a failed import and a delayed payment run. Set your row limit to match your platform's cap, download the numbered output files, and load them sequentially through your AP tool's bulk upload interface.

How it works

1
Export the invoice batch CSV from your ERP
Pull the full invoice run export from SAP, Oracle, Dynamics, or your AP system — typically a flat CSV with one row per invoice line.
2
Set the row limit to match your payment platform's cap
Use 1,000 for Bill.com, 5,000 for Tipalti, or check your platform's bulk import documentation for its specific limit.
3
Upload each numbered chunk through your AP platform's bulk import
Each output file includes the required header row — upload sequentially and verify invoice counts against the source total after each batch.
