Custom Public Tender Tracking and Bid Management App Cost (2026)

The verdict in three sentences

For a services SME bidding on 120 public contracts a year, a custom tender tracking and response app costs EUR 20,000 to 40,000 (GBP 17,000 to 34,000) and ships in 10 to 14 weeks. It centralises TED and Find a Tender feeds (plus BOAMP for French tenders), up-to-date compliance documents and a library of reusable bid answers with AI drafting support. The measured gain is around 30% less response time, while a tender alert subscription at EUR 150 to 600 per month only covers detection.

Alert service or custom tool: what changes

Commercial alert platforms find notices well. Time is lost elsewhere: digging out current insurance certificates and accounts, the case studies from the same sector, rewriting the methodology section for the tenth time. The custom tool links detection, the bid / no-bid decision and bid production.

Both approaches are often combined: the SME keeps a light subscription for buyer portals poorly covered by public APIs, and the internal app handles everything else.

Detailed budget and timeline

The AI assistant does not write a full bid for you. It suggests paragraphs from your winning answers, adapted to the tender specification, which the bid writer approves. Model usage costs stay modest: EUR 30 to 120 per month for 10 bids a month.

Mini case study

Sophie, sales director of a facility management SME, bids on 120 tenders a year in France and the UK. Each bid takes 22 hours on average (tracking, documents, written answers, review), or 2,640 hours a year. With a 30% gain, she recovers 790 hours. At a loaded cost of EUR 45 per hour, savings reach about EUR 35,500 a year. Her project costs EUR 32,000 plus EUR 7,800 of annual support. Payback arrives in 11 months. Another effect: with the time freed, her team can bid on 20 more tenders. At a 25% win rate and EUR 60,000 average revenue per contract, that is EUR 300,000 of potential extra revenue.

FAQ

Is tender data available for free?

Yes, TED, Find a Tender and BOAMP publish notices as open data with APIs. The connector costs EUR 4,000 to 7,000 to build, with no subscription afterwards.

Can AI produce a compliant bid?

It speeds up drafting by reusing your best paragraphs, but approval stays human. Expect 30 to 40% less drafting time on methodology sections.

Are our confidential documents protected?

The app is hosted in the EU or UK, with encryption and per-user rights. Content sent to the AI model is not used for training under business provider terms.

Can we manage consortia and subcontractors?

Yes, a consortium module (lot allocation, lead partner documents) adds about EUR 3,000 to 5,000.

What if we bid on fewer than 40 tenders a year?

Below 40 bids, an alert subscription and a well-kept shared library are often enough. A custom tool pays off above 60 to 80 bids a year.
