The short version

  • Only Arnica has a free tier, so it costs nothing to try first.
  • Each has a real cost: Arnica per-identity pricing ($25-$50/person/year) requires tracking active developers; Bidnet Direct suppliers pay for aggregation, not access: the same solicitations are generally published free on individual agency and state portals, so the subscription is only worth it if searching manually costs more than the fee.
  • They diverge on capability: Arnica covers AI SAST, Bidnet Direct covers Regional purchasing groups.
  • Prices and features above were last checked on 31 August 2026.

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Arnica

  • Per-identity pricing ($25-$50/person/year) requires tracking active developers
  • Overage identity tracking via 90-day PR activity can be unpredictable
  • Free plan limited to weekly updates, requiring upgrade for real-time scanning
  • Advanced add-ons (Image Scanning, AI SAST, Agentic Rules Enforcer) pricing not published
  • On-premises deployment limited to Enterprise tier

Bidnet Direct

  • Suppliers pay for aggregation, not access: the same solicitations are generally published free on individual agency and state portals, so the subscription is only worth it if searching manually costs more than the fee.
  • Supplier pricing is not published and varies by geography and category breadth, which makes it difficult for a small contractor to judge value before a sales conversation.
  • Category matching produces a high volume of irrelevant alerts for suppliers whose work does not map neatly onto procurement commodity codes, so the notification stream needs constant tuning.
  • Bidnet is now one brand inside SOVRA, which divested six business units in 2025 under new private equity ownership, so portfolio priorities can change independently of any individual product's customers.
  • For agencies it is a publication and notification network rather than a sourcing system: bid evaluation, scoring and contract management need a separate tool.

Answered from the vendors’ own pages

Arnica: How are identities defined in Arnica pricing?

Identities are any users and other contributing entities that contributed code and/or had PR activity during the last 90 days. This ensures billing matches active developers.

Source
Bidnet Direct: Do government agencies pay?

Generally not, or very little. The network is funded by supplier subscriptions, which is why agencies get an existing supplier pool without paying for it.

Arnica: What is the annual discount?

Annual prepayment offers approximately 17% savings versus monthly billing. Core Business annual is $300/identity versus $360 for monthly.

Source
Bidnet Direct: Is it worth it for a supplier?

Only if aggregation saves you more than it costs. The solicitations are public and available free elsewhere; you are buying alerting and search across many agencies at once.

Arnica: Can I cancel or downgrade Arnica anytime?

Yes. Subscriptions can be cancelled or downgraded at any time. Overage identities receive automatic protection with true-up invoicing.

Source
Bidnet Direct: Who owns it now?

SOVRA, the rebranded procurement business of mdf commerce, which was acquired by KKR. Bidnet Direct remains a named product within that portfolio.

Bidnet Direct: Does it evaluate bids?

No. It publishes and distributes. Scoring, evaluation and contract management require a sourcing platform.
