Split PDF By Invoice Number & Add Numbers To File Names

 

Multiple invoices combined into one PDF present a pretty tricky problem when it comes to getting through your admin tasks. Ideally you want everything nicely split out into different files but with invoices of potentially varying page length involved, it is not necessarily an easy task.

This is just one of the many situations where our PDF Splitter Pro software stands to save you considerable time and frustration with its advanced PDF splitting functionality. It is not only capable of analysing the contents of your file to identify distinct sections via invoice numbers, you can also extract those numbers and include them in the generated file names. Let's take a step-by-step look at how to split PDF by invoice number and add numbers to the file names.

Step 1: Open up PDF Splitter Pro and select your invoice. In this case we have a file called combined-invoice.pdf on the desktop.

FAQ: Splitting PDF by Invoice Number ▼

Open PDF Splitter Pro, load your combined invoice PDF, set the invoice number field as the text separator, and click Start. Each invoice becomes a separate file named with its invoice number.
PDF Splitter Pro handles this automatically. It reads the text on each page and splits at invoice boundaries regardless of whether an invoice is 1, 2, or 5 pages long.
Yes. The built-in renamer uses the separator text (invoice number) as part of the filename. Each output file is named descriptively.
Yes. PDF Splitter Pro handles PDFs with thousands of pages and hundreds of invoices. Processing is fast even for large files.
Yes. Set up the splitting rules in the GUI, then use the command line to run the same job automatically when new invoice PDFs arrive.
Yes. You define which text position marks the start of each invoice. The tool adapts to any layout — as long as the separator text is consistent.
Load the combined PDF into PDF Splitter Pro, switch to the text-based split mode, and specify the text line that appears on the first page of every invoice — typically the invoice number field. Click Start: the program cuts the file at each occurrence and saves every invoice as a separate PDF, named by its invoice number.
Yes. Accounting systems often print hundreds of invoices into one PDF spool file. As long as each invoice starts with a consistent text line (invoice number, customer code, document date), PDF Splitter Pro separates the spool into individual invoices in one run — no manual page counting.
Yes. The separator is any text line you define. Companies use the same mode to split PDFs by purchase order number, account number, policy number, or patient ID — and the renamer puts that value into each output file name.
No. The 30-day trial is fully functional with no credit card or email required, so you can test the text-based splitting on your own invoice batches first. A lifetime license is $99 — one payment, no subscription.
