Can I combine invoice exports from multiple vendors into one AP register?

Yes. Upload all vendor invoice files and enable 'Include source file name.' Each invoice row will be tagged with its vendor file, giving you a unified AP register with full vendor attribution for matching and approval workflows.

What if different vendors include different columns on their invoices?

Deliteful outputs the union of all columns. A PO number column present in one vendor's file but not another will appear for all rows, with empty cells for vendors who don't include it. This preserves all vendor-specific data in the consolidated file.

Does the output work as a bulk import file for ERP systems?

The combined .xlsx is a clean flat file. Whether it matches your ERP's required import schema depends on that system's requirements. You may need to reformat or rename columns to match the ERP's invoice import template.

Can I combine invoice sheets from multiple periods into one quarterly AP dataset?

Yes. Upload all period files at once and enable 'Include source file name.' If files are named with the period (e.g. 'invoices-jan-2025.xlsx'), each invoice row retains its period tag for quarterly reconciliation or audit purposes.

Consolidate Vendor Invoice Excel Sheets Into One File for Accounts Payable Processing

Accounts payable teams receiving invoice data from multiple vendors or systems often get separate Excel exports — one per vendor, one per period, or one per subsidiary. Before invoices can be matched, approved, or imported into the ERP, all of that data needs to be in one place. Deliteful's Excel Combine Sheets tool consolidates vendor invoice sheets into a single file in seconds.

A mid-size AP department processing invoices from 20+ vendors may receive Excel submissions on different schedules, each formatted differently. Vendor A includes a PO number column; Vendor B doesn't. One subsidiary exports invoices monthly; another sends them weekly. Manually stacking these into a master AP register before the ERP import wastes time and introduces alignment errors that cause payment delays or duplicate processing.

Deliteful reads first-row headers from every sheet across all uploaded workbooks and outputs the column union in one combined worksheet. Vendor-specific columns appear for all rows; missing columns get empty cells. Enable 'Include source file name' and each invoice row is tagged with its vendor or period file — essential for three-way matching workflows and AP audit documentation.

How it works

1
Collect vendor invoice exports
Gather .xlsx or .xls invoice submissions from each vendor or subsidiary for the period being processed.
2
Upload all files to Deliteful
Drop all vendor files in one job — multiple workbooks and multiple sheets per workbook are all combined.
3
Tag rows by vendor or period
Enable 'Include source file name' so each invoice row is labeled with its source vendor or period file.
4
Download and import into your ERP
Use the consolidated sheet as your AP register input or ERP bulk import file for the period.
