Firmex does not publish pricing on its website. Every Firmex quote starts with a sales call and is scoped against deal duration, storage, user count, and feature set. Reported customer pricing falls into two shapes: a monthly subscription scoped to mid-market deal teams (typically reported in the $625-$995/month range for entry tiers, depending on the plan and customer size), and a per-project / per-deal quote that typically lands at $5,000-$10,000 per three-month engagement for mid-market M&A. Enterprise and multi-room subscriptions commonly run $25,000+/year. This guide explains what each tier includes, where the budget surprises hide, and how Firmex compares with Papermark, iDeals, and Datasite.
Firmex sits in the middle of the VDR pricing spectrum. It is more transparent than Datasite or Intralinks (which are full custom-quote only), but less transparent than Papermark, SecureDocs, or CapLinked, which all publish flat-rate plans on the website. Two pricing models are in play.
Firmex does not publish a price list. Reported subscription rates from third-party customer data points cluster around $625-$995/month for entry tiers, depending on plan and customer size. The subscription includes Firmex's core feature set (role-based permissions, Q&A module, audit trail, dynamic watermarks, two-factor authentication) and is typically scoped to a single data room with limited users and storage. Larger deals upgrade to multi-room or enterprise tiers, which are custom-quoted.
For the mid-market and enterprise segment that is Firmex's core customer, pricing is typically scoped per project. A representative engagement runs $5,000-$10,000 for a three-month project, including:
Per-project pricing has clean economics for time-boxed deals: a sell-side M&A process that completes in a quarter pays once and archives the room. It becomes expensive when deals stretch past the project length, when a firm runs multiple back-to-back deals on different rooms, or when the buyer wants ongoing access for IR or LP communications post-close.
Firmex publishes high-level plan tiers but not the underlying numbers. The descriptions below are based on representative customer quotes verified in 2026.
| Plan | Typical price | Best for | Limits |
|---|---|---|---|
| Basic / Starter subscription | Reported ~$625-$995/month | Small deals, single data room | Limited users, limited storage |
| Professional / Mid-market | $5K-$10K per 3-month project | Mid-market M&A, legal diligence | Project-bounded; ongoing use re-quoted |
| Unlimited / Enterprise | Custom (often $25K+/year) | Corporate development teams running multiple deals | Subject to fair-use clauses |
| Per-deal one-shot | Custom quote | Single-project sell-side or IPO support | One room, one engagement |

A typical Firmex subscription or project includes the core VDR feature set:
What is sometimes outside the base price (and added at higher tiers or as paid add-ons):
Firmex's per-project model is clean when a deal completes on schedule. Three places budget tends to drift.
Project extension fees. If a deal slips past the original three- or six-month window, Firmex re-scopes and re-quotes. This is normal for the model but can add 25-50% on top of the original quote depending on the renewed term.
Multi-room engagements. A single subscription typically covers one data room. For deal teams running multiple concurrent rooms (corporate development, M&A boutiques running parallel mandates), each additional room is a separate quote.
Per-user upcharges. Entry plans cap users at small numbers. Adding external counsel, multiple bidders, or a 30-person LP list pushes the engagement into a higher tier.
Storage overage. Standard subscriptions include moderate storage. Document-heavy deals (M&A with thousands of contracts, real estate portfolios with floor plans, biotech with image-heavy clinical files) commonly exceed the included tier and trigger overage pricing.
Renewal pricing. Annual contracts are often offered with introductory pricing that resets at renewal. Always model two- and three-year total cost of ownership before signing.
