1. Continuous numbering across multiple files
A useful batch tool should carry the sequence from one PDF to the next. If a 12-page pleading begins at MATTER-000101, the next file should begin at MATTER-000113. Check whether the software previews the final range before processing and whether it preserves the chosen order.
2. Clear control over document order
File order determines the Bates range assigned to every document. Look for visible page counts, manual reordering, filename sorting and folder-aware sorting. The interface should make it difficult to confuse the source name, output name and final sequence.
3. Privacy architecture, not only a privacy promise
“Secure upload” and “no upload” describe different architectures. A cloud processor receives document bytes and may delete them later. A local browser processor performs the transformation on the user’s device. Both models can be appropriate, but the distinction matters for sensitive client material and should be stated clearly.
4. Duplicate visibility and manual control
Exact duplicate detection can prevent accidental repeat pages, but automatic deletion without review is risky. A repeated copy may be intentional. Good Bates numbering software identifies the duplicate, preserves the original and lets the user decide whether the copy belongs in the output set.
5. Scan and image handling
Legal document sets often contain JPG or PNG scans alongside PDFs. Compare which image formats are accepted, how they are converted, which page size is used and whether the resulting identifier remains readable on portrait and landscape pages. Password-protected and digitally signed PDFs also need a clear handling policy.
6. Preview and existing-number safeguards
A preview should show the real source page with the proposed identifier, not only a generic white sheet. It should be possible to inspect different documents and the first or last page. No tool should imply that it has validated an existing Bates stamp unless it actually performs that analysis.
7. Output naming and control reporting
The numbered PDFs are easier to review when output filenames include the assigned range. A separate report should record the source filename, output filename, page count, first identifier and last identifier. That report does not replace review, but it gives the reviewer a concrete checklist.
8. Pricing that matches real batch sizes
Compare limits using pages rather than only files. Two PDFs can contain 20 pages or 20,000 pages. A one-time price is often sensible for occasional productions, while a monthly page allowance is easier to budget for recurring work. Check whether unused pages expire, when subscription allowances reset and whether payment is required before the tool confirms that the browser can process the batch.
Feature comparison checklist
| Criterion | Question to ask | BatesBundle approach |
|---|---|---|
| Batch continuity | Does one range continue across every included file? | Yes, in the reviewed order |
| Document transfer | Are source files sent to a processing server? | No, processing is local |
| Ordering | Can files be sorted and manually moved? | Sort, drag, move up or down |
| Duplicates | Can exact duplicates be reviewed before exclusion? | Flagged and excluded by default, with user control |
| Scans | Can images become numbered PDF copies? | JPG and PNG supported |
| Existing markers | Does the tool claim to remove or validate them? | No; users preview and review |
| Reporting | Is there a file-by-file identifier record? | CSV control report |
| Billing unit | Are limits based on files or source pages? | Source pages |
When a focused tool is the better choice
Full e-discovery platforms and general PDF suites solve broader problems. A focused Bates numbering tool is useful when the immediate job is narrower: assemble a known set of documents, control their order, apply a continuous identifier range and save reviewable output copies without a lengthy implementation.
The responsible user still decides which documents belong in the set and verifies the output. Software should make that repetitive work faster and clearer, not hide the decisions that require professional judgment.
