Feature evidence

Fourteen capabilities compared

Yes requires public evidence that the complete capability exists in at least one current plan. Partial means narrower or adjacent functionality. If the research did not establish the capability, it is marked not offered.

CapabilityBidSkimOpen Opportunities
AI or semantic matchingYes

Monitor and Predict provide complete ongoing profile-based matching: every new notice is scored 0-100 against services, region, value and certifications with written reasons. The Free plan's one-off scan is plan gating, not an incomplete paid capability.

BidSkim features ↗BidSkim pricing ↗
Yes

Intent Search uses Open Opportunities' own AI model to score and rank results across geographies, languages and currencies, and is described as assessing document meaning rather than only keyword occurrence.

Intent Search ↗AI for bid writers guide ↗
Buyer profilesYes

Predict includes structured cross-notice buyer profiles with requirements, spend and award history, top suppliers, contacts, renewals and researched notes. Public data documentation states that repeated notices are deduplicated and lifecycle notices are connected; Predict gating does not downgrade the capability.

BidSkim features ↗BidSkim pricing ↗BidSkim data coverage ↗
Not offered

Users can search or monitor buyer names and inspect past records, winners, values and buying patterns. The provider documents notice-level deduplication and field validation, but not buyer-entity resolution or structured cross-notice buyer profiles.

Sales strategy ↗Search user guide ↗Data quality reports ↗
Supplier profilesYes

Predict includes structured supplier and incumbent profiles that aggregate wins, buyers, regions, categories, awarded values, held contracts and renewal exposure across the award record. This is a complete current-plan capability even though public pages do not describe the exact alias-resolution algorithm.

BidSkim features ↗BidSkim terms ↗
Not offered

The contract database can be filtered by supplier name to find awards, but the reviewed pages do not establish deliberately built cross-notice supplier entities, identity resolution or structured supplier profile pages.

Search by supplier ↗
RenewalsYes

Predict provides complete renewal timing signals built from public award, contract, modification and termination records. Exact dates, durations and extension options are converted into source-linked planning dates, refreshed daily and ranked against the subscriber profile; the provider explicitly distinguishes these from confirmed re-tender dates.

BidSkim features ↗BidSkim data coverage ↗BidSkim pricing ↗BidSkim contract timing method ↗
Yes

Open Opportunities supports alerts for expiring contracts and competitor tracking; current pricing lists expiring contracts awarded in the last five years, and its data includes contract start/end dates.

Open Opportunities home ↗Open Opportunities pricing ↗Coverage and data fields ↗
Similar contractsYes

Predict surfaces comparable historical awards matched by contract scope rather than shared keywords, including winners, values, terms, bid counts and SME status where published. Higher-tier gating does not make the implemented capability partial.

BidSkim features ↗BidSkim data coverage ↗
Partial

Open Opportunities' documented workflow tells users to manually search for similar contracts and review similar past tenders, buyer history and values. The reviewed pages do not establish an automatic related-contract panel surfaced against a notice or profile.

Sales strategy ↗
Buyer document corpusNot offered

The reviewed public pages do not establish a full searchable corpus of buyer-authored documents designed to surface upcoming work.

BidSkim product ↗BidSkim features ↗
Not offered

The platform gathers notice attachments and planning notices, but the reviewed pages did not establish buyer strategies, minutes, budgets or other non-notice buyer-authored document collections.

Buyer requirementsYes

Predict buyer profiles organize insurance, certifications, social-value rules, local preferences and pass/fail gates drawn from public buyer records and documents. The capability is complete on Predict; Monitor exclusion is plan gating.

BidSkim features ↗BidSkim pricing ↗
Not offered

Records and attachments expose source notice content, but the reviewed pages did not establish extracted or organised participation conditions, certifications, policies or evaluation criteria.

Requirements planningPartial

Predict is positioned for preparing certifications, evidence and answers before a tender goes live using buyer requirements and likely renewals; no separate task-based readiness workflow is described.

BidSkim pricing ↗BidSkim features ↗
Not offered

The provider publishes strategic planning guidance and offers planning notices, but the reviewed pages did not establish an in-product gap, readiness, evidence or requirements-planning workflow.

Award historyYes

The service offers a one-off 12-month matched-award report on Free and five years of connected buyer and award history, comparable awards and supplier intelligence on Predict. Tier-specific lookback and access do not make the capability partial.

BidSkim data coverage ↗BidSkim features ↗
Yes

The platform includes historic tenders and contract awards, including supplier, buyer, value and award dates; users can search suppliers and inspect previous winners and prices.

Data feature breakdown ↗Search by supplier ↗Open Opportunities pricing ↗
FrameworksYes

BidSkim badges frameworks, DPS and dynamic markets, filters out non-joinable call-offs and modifications, and shows application/end dates, supplier caps and route-in information.

BidSkim features ↗
Yes

Open Opportunities says it tracks central-government frameworks, supports analysis of framework award terms and reopening windows, and includes framework records in its historical procurement data.

Data feature breakdown ↗SME Procurement Act guide ↗
Competitor trackingYes

Predict provides complete named-supplier tracking across public-sector wins, buyers, awarded values, regions, categories and contracts nearing expiry. Monitor exclusion is plan gating, not an incomplete implementation.

BidSkim features ↗BidSkim pricing ↗
Yes

The product page advertises tracking of competitors, buyers and categories; users can alert on competitors and search awards by supplier to see who has won contracts.

Tender alert features ↗Open Opportunities home ↗Search by supplier ↗
Exports or APINot offered

No CSV/Excel export, API, webhook or CRM integration is documented on the reviewed pages; the pricing page says large teams needing exports may be better served by enterprise platforms.

BidSkim pricing ↗
Yes

Team includes CSV downloads of up to 100 rows. A separately priced REST API returns structured JSON, documents and daily updates and supports CRM, dashboard and alert-routing integrations.

Open Opportunities pricing ↗Open Opportunities API ↗
Team workflowPartial

Monitor and Predict can deliver alerts to up to three teammates and include a pipeline, but no multi-user seats, assignments, comments or shared-workspace permissions are documented.

BidSkim pricing ↗BidSkim features ↗
Yes

The Team plan includes unlimited users; provider guidance describes sharing opportunities and insights with colleagues and setting up team members. The API can route alerts to Teams or Slack.

Open Opportunities pricing ↗Sales strategy ↗Open Opportunities API ↗
Bid writingNot offered

The pricing FAQ explicitly says BidSkim does not write bids and focuses on finding, qualifying and researching opportunities before the bid.

BidSkim pricing ↗
Not offered

Open Opportunities publishes guidance about using AI for bid writing, but the reviewed product pages did not establish response drafting, an answer library, compliance matrix or managed writing as a platform feature.

Practical fit

Which should make your shortlist?

Shortlist BidSkim when

British suppliers wanting profile-based qualification and links back to official notices.

Public-evidence advantages: Buyer profiles, Supplier profiles, Similar contracts, Buyer requirements, Requirements planning.

Watch for: Teams needing managed bid writing or coverage outside Great Britain. The provider says it does not write bids. Its score is a qualification aid, not a buyer decision or award forecast.

Shortlist Open Opportunities when

International tender teams or data users that need more than UK-only feeds.

Public-evidence advantages: Exports or API, Team workflow.

Watch for: A small UK supplier seeking a low-cost national alert product. The global source count is provider-stated. Test the exact countries and UK portals you need.

  3. How do expiring-contract alerts handle extensions, contract modifications, early termination and source records with missing or estimated end dates?
  4. Which current privacy policy governs the service, where is customer data hosted, and what encryption, MFA, subprocessors, retention, incident-response and independent assurance controls apply?
  5. What are the actual month-to-month Solo, Team and API prices, renewal uplift rules and API rate/volume limits?
  6. Can Team users collaborate beyond sharing and bookmarks, and can all account searches, records and watchlists be exported on exit?
