Frequently asked questions
What is the difference between PSIP and Tenderlake?
PSIP is a UK-focused procurement intelligence platform covering five UK procurement sources, with transparent pricing from £99/month and a 7-day free trial. Tenderlake positions itself as a broader platform with UK, Ireland, and European coverage, demand signals, and Slack/Teams workflow integration. PSIP's key differentiator is Claude AI relevance scoring on every tender — a 1–10 score with written reasoning — against your specific business profile.
Which is cheaper — PSIP or Tenderlake?
PSIP starts at £99/month with a 7-day free trial and no credit card required. Tenderlake's published pricing starts from £249/month annually (or £325/month monthly). PSIP is significantly more accessible for smaller suppliers and SMEs.
Does Tenderlake cover more data sources than PSIP?
Tenderlake markets broader source coverage including UK, Ireland, and European opportunities on higher plans. PSIP covers all five UK procurement sources — Find a Tender, Contracts Finder, Public Contracts Scotland, Sell2Wales, and eTendersNI — covering all UK regions including devolved administrations. For UK-only suppliers, PSIP's coverage is comprehensive.
Which tool has better AI features?
Both platforms use AI for opportunity discovery. PSIP uses Anthropic's Claude to score every tender 1–10 against your specific business profile, with a written explanation for each score. This per-tender relevance scoring helps active bidders filter by relevance rather than keyword. Tenderlake uses AI for demand signals and opportunity discovery, with Slack/Teams routing for team workflows.
Which is better for bid agencies?
PSIP's Bid Agency plan includes dedicated client workspaces — separate business profiles, AI scoring, and searches for each client. When you switch workspace, AI scoring automatically uses that client's profile. This multi-client architecture is purpose-built for bid agencies managing several clients simultaneously.
