The verdict in three sentences
An engineering SME answering 80 public tenders a year with spreadsheets and shared folders mostly loses time on contracts it never had a real chance of winning. A custom tender tracking and bid management app costs, as a 2026 order of magnitude, €18,000 to €35,000 excluding VAT, delivered in 10 to 12 weeks, and combines TenderNed and TED aggregation, a scored bid/no-bid decision, a content library and automatic back-planning. The realistic goal is to bid less often on better-chosen tenders, with a target win rate of 20 to 30% instead of the 10 to 15% common among SMEs that bid on everything.
What market tools cover, and what they leave out
TenderNed sends free alerts for Dutch public tenders, and commercial aggregators add regional and private buyers. They do one thing well: spotting notices and fetching tender documents. They do not handle the decision to bid, the reuse of content or team coordination up to submission. Bid management SaaS goes further, but with standard workflows designed for large groups.
| Tool | What it covers | Cost (2026 order of magnitude) |
|---|---|---|
| Spreadsheets and shared folders | List of tenders, scattered files | €0 licence, hidden cost in time |
| TenderNed alerts | Dutch public notices by CPV code | Free |
| Commercial tender aggregator | Alerts across buyers and countries, documents | €1,000 to €4,000 a year |
| Bid management SaaS | Library, collaboration, tracking | €3,000 to €12,000 a year |
| Freelance bid writer | One-off drafting of a technical proposal | €1,500 to €5,000 per tender |
| Custom app | Tracking, bid/no-bid, library, back-planning, analytics | €18,000 to €35,000, then maintenance |
Alerts alone do not fix the core issue: 80 bids a year means about 320 days of engineers' and account managers' time, a large share of it on tenders lost from the start.
Modules and their cost
TenderNed publishes Dutch notices as open data and the EU exposes TED notices through a free API, so aggregation is reliable and costs nothing on the data side. The budget goes into the intelligence layered on top.
| Module | What it does | Cost (2026 order of magnitude) |
|---|---|---|
| TenderNed and TED aggregation | Daily import, filters by CPV code, region and value | €3,000 to €5,000 |
| Scored bid/no-bid | Weighted criteria, decision history | €2,500 to €4,500 |
| Content library | Proposals, references, CVs, certificates with expiry dates | €4,000 to €8,000 |
| Automatic back-planning | Milestones from the deadline, reminders | €2,000 to €4,000 |
| Collaboration and sign-off | Section owners, review, management approval | €3,000 to €6,000 |
| Dashboard | Win rate, loss reasons, competitor awards | €2,500 to €5,000 |
| SSO, hosting, acceptance testing | Secure login, go-live | €1,000 to €2,500 |
| Total | €18,000 to €35,000 |
The library deserves special care. An expired Uniform European Procurement Document (UEA) statement, a lapsed insurance certificate or an outdated Gedragsverklaring Aanbesteden can make a bid non-compliant; the app flags each expiry 30 days ahead.
What a disciplined bid/no-bid changes
Bid/no-bid turns a gut feeling into a score: technical fit, comparable references, likely competition, expected margin and team workload over the period. Below a threshold, the SME does not bid, or bids as a partner in a consortium.
| Indicator | Before (spreadsheets) | Target after 12 months |
|---|---|---|
| Tenders answered per year | 80 | 60 |
| Average time per bid | 4 days | 3 days |
| Win rate | 15% | 25% |
| Contracts won | 12 | 15 |
| Bids rejected for missing or expired documents | 4 a year | 0 to 1 |
| Time spent finding references and CVs | 3 hours per bid | 30 minutes |
These targets are not a guarantee; they depend on proposal quality and the market. They are consistent with what happens when an SME stops bidding on everything.

Mini case study
Sanne, commercial director of a 45-person engineering firm in Amsterdam, answers 80 tenders a year at 4 days each, or 320 days. With bid/no-bid, she handles 60 at 3 days, or 180 days: 140 days freed, at €550 per engineer day, are worth €77,000 of capacity moved back to billable work. If the win rate rises from 15 to 25%, the firm wins 15 contracts instead of 12; at €80,000 average revenue and 15% margin, the 3 extra contracts bring €36,000 of margin. Against a €28,000 build and €4,800 a year of maintenance, the investment is covered within a year, even if real gains reach only half of these assumptions.
FAQ
Is TenderNed and TED data freely available?
Yes, TenderNed publishes Dutch notices as open data and TED offers a free public API. Some below-threshold and private tenders appear only on buyer portals, so keeping an aggregator subscription at €1,000 to €2,000 a year alongside the app is often worthwhile.
How long until we are operational?
Allow 10 to 12 weeks, including 2 weeks to define bid/no-bid criteria and import existing proposals. Automated tracking can run from week 5.
Can the app write technical proposals?
It suggests blocks from the library, organised by tender type and reference. AI drafting assistance can be added and is quoted separately, but every proposal still needs review by an engineer.
Do we submit bids from the app?
No, submission always happens on the buyer's platform, such as TenderNed or a regional portal. The app prepares the complete file and records the submission date and time.
What win rate is realistic?
As a 2026 order of magnitude, 20 to 30% for an SME that selects its tenders, against 10 to 15% when it bids on everything. The dashboard tracks progress quarter by quarter.
