Working with Attachments in Precoro


In Precoro, you can add file attachments to each new document created:

  • Purchase Order (there are two attachment types available: Internal and External)
  • Warehouse Request 
  • Purchase Requisition
  • Request for Proposal
  • Receipt 
  • Invoice 
  • Expense.

Available Formats and Volume Limitations


The available attachment volume in a document should not exceed 25 MB.

With the overall limitation of 25 MB, you can upload any amount of files as long as they do not exceed the limit.

You can upload various file formats: webp, jpeg, pjpeg, png, tiff, gif, xml, csv, pdf, heic, msg, and zip. Also please note that the file preview is available for the pdf, png, and jpeg formats.

You cannot add zip and heic format attachments for companies integrated with QuickBooks.

If you attach a zip or heic format file to a document in Precoro and send it to QuickBooks, it will be transferred without this attachment.
