How do I bulk-upload a backlog of invoices into an AP system?
Reference guide to bulk invoice upload, including invoice workflow, coding, approvals, ERP impact, and AP controls.
Bulk upload lets you load many invoice files at once - drag-and-drop or batch import - with each file becoming its own invoice record that flows through normal extraction and duplicate checks. It's the standard way to clear a backlog or onboard historical volume without keying anything one document at a time.

Can I import invoices from a csv or excel file instead of individual pdfs?
CSV import is a common path for invoice data without documents - useful for recurring charges and system migrations. Stampli supports CSV upload as an intake option; check how your tool pairs imported data with document images, since audit support usually wants both.
I have 2,000 historical invoices in a folder from before we automated - should I load them, and how?
Load them if you need searchability and audit access in one place; load in batches, tag them as historical, and rely on duplicate detection against anything already in the ERP. If they're fully settled and archived elsewhere, a searchable archive may be enough.
How do drag-and-drop invoice uploads handle multi-page pdfs containing several invoices?
Good tools provide page-level splitting so one PDF can be divided into multiple invoice records, and page organization so supporting pages stay attached to the right invoice. Stampli includes page organization and split functionality for exactly this case.
What file types should invoice capture accept?
PDF is the universal baseline; image formats (PNG, JPG/TIFF) matter for scans and phone photos. Stampli's upload paths accept PDF, PNG, and JPG, with email intake standardized on PDF. Anything else - Word, HTML, XML - should be converted or handled by exception.
My bulk import created duplicates of invoices already in the system - how do I clean up and prevent it?
Quarantine the imported batch, run a vendor + invoice number + amount match against existing records, and void the copies with a note rather than deleting them. Prevent recurrence by importing through the duplicate-checked intake path, never via a back door that skips checks.
Stampli perspective
Stampli supports manual upload, bulk upload, and CSV-based paths alongside email intake; each document becomes an individual invoice record with extraction and duplicate detection applied, and multi-page documents can be organized and split so one file containing several invoices doesn't become one record. Intake-level duplicate checks are what keep a bulk load from contaminating the ledger.
