Import Bills into Bill.com from a CSV File

Bill.com (now branded BILL) will load a whole backlog of vendor bills from one CSV file, but only when the file is built the way BILL expects: vendors that already exist, a row for every line, and key fields that match cleanly. It does not read a PDF or a scanned image into a bill on its own. So the work splits in two: turn your invoice documents into clean rows, then import those rows. This guide covers both, with where the import lives, the order to load records, how vendors get matched, and the errors that stop a load. If your bills are still PDFs or photos, drop them into the converter at the top of this page first and you will have an import-ready file in a few minutes.

Can you import bills into Bill.com?

Yes. BILL lets you import bills in bulk from a CSV file instead of keying them one at a time. The import is part of the same data tools you use to sync with an accounting system, so it sits under your settings rather than the bill inbox. You import non-transaction records first, vendors and the chart of accounts, then import the bills themselves. A PDF or photo has to be converted to structured rows before any of this works, because BILL imports data, not documents. Once your data is in a CSV, a month of bills loads in one pass.

How do I import bills into Bill.com?

Export a sample file to get BILL's exact column layout, fill it with your bill data, then upload it through the import tool and map each column to a BILL field. The sequence runs like this:

• Confirm you have the Sync with Accounting System permission, which is what unlocks importing data.
• Import your vendors and chart of accounts first, so every bill has something to match against.
• Export a small CSV of existing bills to see the column headers BILL uses, then build your import file to match.
• Add one row per bill line, repeating the vendor and bill number across the lines of the same bill.
• Upload the CSV, map the columns, and run the import.
• Review the result, and if any rows fail, open the error report, fix those fields, and re-import just the corrected rows.

The part that takes real time is building those rows from PDFs. Converting the documents first with a Bill.com invoice import converter gives you the vendor, dates, line items, and amounts already structured, so you only add the BILL-specific fields.

Does Bill.com import invoices from a PDF?

Not through the CSV import. BILL can capture a single bill from a PDF you email or drop into its inbox, where it reads the document and drafts one bill for review, but that path is one document at a time. The CSV import, the path built for volume, reads structured rows, not files. So for a backlog or a month-end stack, the workflow is to convert the PDFs to a spreadsheet first, then import that spreadsheet. The converter at the top of this page produces exactly those rows.

How does Bill.com match the vendor on an imported bill?

BILL matches on key fields. During the import it checks the key field in your file, usually the vendor name, against the vendors already in your account. If it finds one match, it links the bill to that vendor. If it finds no match, it creates a new vendor, which is how duplicate vendors creep in. If the value matches more than one vendor, the row errors. The safe practice is to import or clean your vendor list first, then use the exact vendor names from BILL in your bill file so every row resolves to one existing record.

How do I import a multi-line bill into Bill.com?

Use one row per line item and repeat the bill-level fields on each row. A bill with four line items becomes four rows that share the same vendor and bill number, while the description, amount, and GL account change line to line. BILL groups the rows that share a bill number into a single bill with multiple lines. This is why clean extraction matters: every line needs its own amount and account, and the bill number has to be identical across the lines, or the bill splits or rejects.

Why is my Bill.com import failing?

Most failed rows trace to a few causes: a vendor name that matches no existing vendor or matches more than one, a missing GL account on a line, a blank required field, a bill number that does not stay consistent across a bill's lines, or a date or amount in a format BILL does not accept. When you update existing transactions, leaving a field blank can wipe the value that was there, so include every field on an update. BILL marks the import as failed and gives you a downloadable error report that names the reason for each row. Fix those fields and re-import only the corrected rows.

Should I import bills into Bill.com if I sync with QuickBooks?

Be careful. If BILL syncs with an accounting system like QuickBooks, BILL recommends against importing records by CSV when those records already live in the accounting system, because you can create duplicates and sync errors. The safe use of CSV import is for data that does not yet exist in either system, such as a backlog of bills you are bringing into BILL for the first time. When in doubt, import a small test batch, confirm it syncs cleanly, then load the rest. Keeping vendor names consistent across BILL and your accounting system avoids most of the trouble.

What is the difference between the Bill.com inbox and a CSV import?

The inbox captures one bill at a time from an emailed or uploaded document and drafts it for review, which is convenient for the steady trickle of bills that arrive day to day. The CSV import loads many bills at once from a structured file, which is the right tool for a backlog, a migration, or a month-end batch. They solve different problems. Most teams use the inbox for ongoing bills and reach for the CSV import when they need to move volume, with the data already converted to rows.

From PDF bills to a Bill.com-ready CSV

The slow part of importing bills into Bill.com is never the upload. It is turning a stack of PDFs and scans into the exact rows the import wants. InvoiceXLSX reads each PDF or photo with AI and returns the vendor, bill number, dates, line items, tax, and totals as structured rows, with one bill number carried across its lines. Paste that into your import file, add the GL accounts and any BILL-specific fields, and you have a CSV ready to load. See the import invoices to Bill.com page for the full converter, and the invoice line item extraction guide for how multi-line bills become clean rows. If you want the raw spreadsheet first, the extract invoice data to Excel walkthrough and the invoice PDF to CSV converter cover that step, and the how to import invoices into an ERP overview compares the path for every accounting system. Once those bills are paid, reconciling them against what cleared the bank is faster when the statement is structured too: if your books are in QuickBooks, a bank statement to QuickBooks converter turns the bank side into a QBO file you can match against. Build the import file once, and a month of bills loads in minutes instead of an afternoon.
