Bringing a large contract repository into Aline — thousands or tens of thousands of documents — works best as a deliberate process: upload in manageable batches, then clean up duplicates and stale records so your reports start from accurate data.

This guide covers uploading at scale and getting the repository tidy afterward.

In this article you'll:

You have a few ways to bring documents in, depending on where they live:

💡 If a sync doesn't pull everything as expected, you can always fall back to manual drag-and-drop upload for the missing files.

For very large sets, upload in batches rather than all at once. Staging the migration — for example, by contract type or by folder — keeps things manageable, makes it easier to spot problems early, and lets you start labeling and reviewing one group while the next uploads.

If you're pulling from a large source system, you often don't need every file. Filter the source down first — for example, using keywords and AI to target the document types you actually care about (like MSAs) — so you bring in the relevant subset instead of tens of thousands of unrelated files.

Large repositories almost always contain duplicates. To deduplicate:

📌 Exporting this to a spreadsheet can help when you're working through a very large set with a colleague.

Once documents are in, use reports to finish the cleanup:

💡 Best Practice: Do the cleanup — dedup, status, labels — before you run large AI reports. Clean input means accurate output, and it keeps you from spending tokens processing duplicates and dead contracts.
