Part 1

What this upload proves

The joint venture attachment shows how the JV is structured, registered, represented, and eligible for MAS offer review.

It belongs in the entity, responsibility, teaming, and pricing-file lane.

Part 2

How to prepare it cleanly

Start by naming the proof role, file owner, source system, date pulled or signed, and whether the file is required, conditional, or optional for the selected offer.

Then compare the file against the pricing workbook, SAM record, eOffer narrative, and category/SIN instructions so the package tells one story.

  • JV is registered in SAM as its own legal entity where required.
  • Partner MAS contract and audit facts are disclosed.
  • Pricing files and partner contributions are explained.
Part 3

What to watch before upload

Treating the JV as just another teaming note can miss entity-level and partner-level requirements.

Use filenames that help the reviewer understand the document before opening it. A clear file name with document type, company, SIN or category when relevant, and date is usually better than an internal shorthand.

The upload goal is calm review: current file, clear purpose, no contradictions.
Examples

What this looks like in practice
