ESM Purchase
These limits apply to each transaction record. A transaction includes its header and all of its line items. There are two types of attachments: Internal Notes attachments and External Notes attachments.
File size limits
| Limit | What it covers | Maximum |
|---|---|---|
| Individual file | Any single attachment, internal or external | 20 MB |
| External Notes attachments (total) | All external attachments on the header and all line items combined | 15 MB |
| Internal Notes attachments (total) | All internal attachments on the header and all line items combined | 250 MB |
| All attachments (total) | Every internal and external attachment on the transaction | 500 MB |
Note: The External Notes total is 15 MB, so in practice no single external attachment can be larger than 15 MB, even though the per-file limit is 20 MB.
Number of attachments
| Where the file is attached | External Notes | Internal Notes |
|---|---|---|
| Transaction header | 5 files | 25 files |
| Each line item | 5 files | 25 files |
| Whole transaction (header and all line items, both types) | 100 files combined | |
File names
File names can be up to 100 characters long. Rename longer files before you upload them.
Good to know
- Deleting frees up space. When you delete an attachment, it no longer counts toward the size or number limits. When you delete a line item, its attachments are removed too.
- Change orders carry attachments forward. A new change order starts with every attachment from the previous version, and those attachments count toward the change order's limits. The limits apply to each version separately. They are not added up across versions.
- Tip for large files: If you reach a limit, compress the file, save it in a smaller format such as PDF, or remove attachments you no longer need.
