Free buyer tools · no obligation
Greenhouse procurement tools
Compare supplier proposals on the same criteria, break your budget into cost lines, plan the project timeline and send one structured RFQ — all on one page. You enter every number; nothing here is a quote, price benchmark or schedule promise.
These tools are free for buyers. Assisted supplier sourcing is for projects from USD 250,000; smaller requests are still reviewed. Your figures stay in this browser until you choose to send the RFQ.
1. Supplier comparison table
Score each proposal 1–5 against your written requirement and set how much each criterion matters (weight 0–5). Totals are out of 100. A higher score is your judgement, not an endorsement of any supplier.
| Criterion | Weight | Proposal A | Proposal B | Proposal C |
|---|---|---|---|---|
| Scope coverage | ||||
| Technical fit | ||||
| Capacity & references | ||||
| Delivery schedule | ||||
| Installation & commissioning | ||||
| Operating cost (OPEX) | ||||
| Maintenance, spares & support | ||||
| Risk & contract terms | ||||
| Total price (CAPEX) | ||||
| Weighted total (/100) | — | — | — | |
Check exclusions and assumptions before scoring price: compare only proposals quoted against the same scope. Detailed method: supplier bid scorecard guide.
2. Cost breakdown calculator
Enter your own estimates or quoted amounts per package. Leave a line blank if it is not in scope. The calculator adds your contingency and shows each line's share — it contains no built-in prices.
| Cost line | Amount (USD) | Share |
|---|---|---|
| Structure & cover | — | |
| Heating, cooling & ventilation | — | |
| Irrigation & fertigation | — | |
| Controls & sensors | — | |
| Lighting & shading | — | |
| Energy & water supply | — | |
| Site works & foundations | — | |
| Freight, duties & customs | — | |
| Installation & commissioning | — | |
| Packing / storage | — | |
| Spares & training | — | |
| Subtotal | USD 0 | |
| Contingency | USD 0 | |
| Total budget estimate | USD 0 | |
Need OPEX, reserves and funding gaps too? Use the greenhouse budget planner · commercial greenhouse cost guide.
3. Timeline planner
Choose a start date and enter the weeks you expect for each phase, ideally from written supplier and adviser estimates. Phases run one after another; leave a phase blank to skip it. Durations depend on your site, permits and suppliers — there is no standard duration.
| Phase | Weeks | Dates |
|---|---|---|
| Brief & site data | — | |
| Permits & approvals | — | |
| Design & engineering | — | |
| RFQ & supplier proposals | — | |
| Evaluation & contract | — | |
| Manufacturing | — | |
| Freight & customs | — | |
| Installation | — | |
| Commissioning & acceptance | — |

4. Send one structured RFQ
Your budget lines, schedule and comparison weights above are attached to the brief automatically. Our team reviews it before any supplier is approached; supplier contact is optional and not guaranteed. Prefer a fuller specification? Use the RFQ builder.
