The best joint venture tools depend on the stage the venture is in, and most small and mid-sized ventures need only three kinds: a virtual data room while the partners check each other's books and contracts, an e-signature service to sign the agreement, and a shared workspace to run the venture day to day. Accounting for the venture itself matters once it trades, because a joint venture taxed as a partnership files its own return.

There is no single "joint venture platform" that does all of this well for a small business, and the tools that market themselves for deals are built mainly for mergers and acquisitions. What follows is the stack by stage, with products that exist and do what is described, and prices only where the vendor publishes them (checked October 2026). Growing Partners has not tested these products; the descriptions are from the vendors' own pages, and a trial is the way to judge fit.

A virtual data room for due diligence

During a joint venture negotiation each side asks to see the other's financial statements, contracts, licenses, IP registrations and litigation history. A virtual data room is a secure folder system for exactly that: documents shared view-only, access per person, and a log of who opened what. The log matters in a negotiation; it shows which documents the other side actually read.

The established names are built for mergers and acquisitions but serve a joint venture's diligence the same way:

  • Datasite presents itself as virtual data rooms for M&A dealmaking.
  • Firmex describes its data room as being for M&A, due diligence, compliance, litigation and corporate transactions.
  • Ansarada sells virtual data rooms and dealmaking tools.
  • DealRoom positions itself as an operating system for buyer-led M&A, combining a data room with tracking of the diligence process itself, which suits a negotiation with many open requests.

None of these is necessary for a small venture between two businesses that already trust each other. A shared cloud folder with view-only links, one folder per diligence topic and a written index does most of the job. Move to a data room when there are many documents, outside advisers on both sides, or anything sensitive enough that you want an access log.

What a data room for a JV negotiation should hold

  • Formation documents and ownership of each partner
  • Last three years of financial statements and current debts
  • Material contracts the venture would touch (customers, suppliers, leases)
  • Licenses, permits and any certifications the venture relies on
  • IP each partner will contribute or license, with registrations
  • Pending or threatened litigation and regulatory matters
  • Insurance policies and claims history
  • The draft JV agreement and every version exchanged

E-signature for the closing

Under the federal ESIGN Act, a contract in interstate commerce may not be denied legal effect solely because an electronic signature or record was used to form it (15 U.S.C. 7001), so a joint venture agreement cannot be refused effect just because it was signed electronically. Some documents (certain real estate filings, notarized papers) still have their own rules.

Two widely used services publish their prices:

E-signature prices as published, October 2026

Docusign Dropbox Sign
Single user Personal, $11 a month billed annually Essentials, $15 a month
Small team Standard, $30 per user a month billed annually Standard, $25 per user a month, from $600 billed yearly
Larger plans Business Pro, $45 per user a month billed annually Premium, by quote

For a venture that signs a handful of documents a year, the cheapest single-user plan, or the e-signature features already in a document tool you pay for, is usually enough.

A shared workspace for running the venture

Once signed, the partners need a place to talk and a place to track work, visible to both companies without either giving the other access to everything it has.

Shared channels. Slack Connect lets two organizations share channels while each keeps its own workspace; all of Slack's paid plans include direct messages to people outside the organization through it (Slack). Microsoft Teams and Google Workspace have their own ways of working with outside users; use whichever the larger partner already runs.

Shared tracking. A project board in whatever tool one partner already uses, with the other given guest access, is enough for most ventures. What matters is less the software than three habits written into the JV agreement: one owner per task, a regular review (monthly suits most), and a single shared list of decisions made.

Separate books. Keep the venture's money in its own bank account and its own ledger from the first day, even when it is small. Shared costs paid from one partner's account are an easy place for an argument to start.

Accounting and tax for the venture

Practically, that means the venture needs accounting software of its own (any small-business ledger will do) and an accountant who has prepared partnership returns. If the venture pays contractors, it has its own information-return obligations too.

How the venture's profit is split between the partners, and whether a revenue share would be simpler than a jointly owned entity, is covered in revenue share vs equity partnerships. Federal contractors forming a joint venture for a set-aside contract face separate SBA rules; see why federal contractors need to renegotiate their joint ventures.

Questions about joint venture tools

For diligence with many documents and outside advisers, a virtual data room such as Datasite, Firmex or Ansarada; DealRoom adds tracking of the diligence requests themselves. For a small venture between two businesses, a well-organized shared folder with view-only access is usually enough.

With wherever the documents already live (the partners' cloud storage), with e-signature for the closing documents, and with single sign-on if either partner uses it. Ask any vendor to demonstrate exporting the whole data room at the end, since the record of what was disclosed matters if a dispute arises later.

Yes, for a contract in interstate commerce the ESIGN Act prevents it being denied effect solely because it was signed electronically. A few document types have their own formalities.

Rarely. Most small ventures run on tools the partners already have. The JV agreement, a separate bank account and clean books matter more than any platform.
