Two quotations for a creative LED display can look similar while covering different work. One may include a controller, project drawings and installation support; another may leave those items for separate agreement. A useful comparison starts with a shared scope and a record of what each supplier has actually included.
This guide helps buyers organize that comparison before selecting a proposal. It does not assign prices or assume that any particular service is included in a JIAMI TV order. Confirm all specifications, responsibilities and commercial terms in the final quotation.
Give every supplier the same project brief
Record the intended location, display format, dimensions, viewing conditions and content purpose. Identify whether the project is a permanent installation or a temporary application. Provide available site photographs and drawings, and mark any dimensions that still require a survey.
For a shaped format such as an LED sphere display, ask each supplier to identify the proposed configuration and the assumptions behind it. Keep the finished display dimensions separate from packing dimensions and the space required for installation and service.
Issue the same revision of the brief to everyone. When an assumption changes, ask for an updated proposal so the comparison remains meaningful. Do not treat a specification copied from an unrelated product page as confirmation of the offered configuration.
Build an inclusion table before comparing totals
Use one row for each part of the project and one column for each proposal. Record an item as included, excluded, optional or unclear, together with the relevant quotation reference. An empty cell should remain an open question rather than being treated as included.
| Scope item | What to establish |
|---|---|
| Display equipment | Offered model, configuration, dimensions and documented specifications |
| Control and playback | Controller, playback device, software requirements and agreed functionality |
| Mechanical work | Supporting structure, drawings, fabrication and installation responsibilities |
| Site connections | Who provides and installs the required power and signal connections |
| Delivery | Packing, transport, agreed delivery point, unloading and movement inside the venue |
| Handover | Testing, operator instruction, documentation and configuration records |
| Service provisions | Included spare parts, support scope and the written terms that apply |
Keep a separate note for buyer-provided equipment and work. Ask the supplier to confirm compatibility and interfaces where the proposal depends on those items. The cabinet procurement and handover guide provides further questions about component records and spares.
Compare the offered configuration, not just the product name
A shared product label does not establish that two proposals describe the same system. Ask for the specification sheet and drawing associated with each quotation revision. Identify differences that affect the project brief, and ask the supplier to explain their consequences for the intended application.
Where a claim matters to the purchase, request the supporting information for the offered model. For example, establish the conditions attached to a stated performance figure and the configuration to which it applies. Do not convert an unconfirmed marketing statement into a contractual requirement without resolving it with the supplier.
List deviations explicitly. A supplier may propose a different arrangement that suits the site, but it should remain visible in the comparison rather than being silently treated as an equivalent offer.
Assign work at the boundaries between teams
Many omissions occur where one team’s scope ends and another begins. Name the party responsible for site measurement, supporting construction, electrical work, equipment movement, final assembly and commissioning. Identify who must approve each team’s inputs before the next stage proceeds.
Delivery deserves its own review. Confirm the quoted destination and the point at which the receiving team takes over. Use the delivery and site access checklist to establish whether the shipment can reach the installation area using the agreed handling plan. Do not assume that transport to the venue includes unloading or movement through the building.
Write down how the completed system will be accepted
Ask what testing and demonstration the proposal includes, where it will happen and who will attend. Agree which functions, content files and site conditions will be used to assess the delivered system. Record how observations and unfinished items will be documented and resolved.
Include the documents and operator information the buyer expects at handover. Identify configuration backups, equipment identifiers and the contact route for support. Confirm any service, warranty or replacement provisions against the written terms; do not infer them from a headline description of after-sales support.
Reconcile the commercial basis before making a decision
Record the currency, quotation validity, payment milestones and any stated exclusions. Ask the supplier to identify which delivery charges, taxes or other project costs are covered and which require separate confirmation. Refer questions about applicable tax or import obligations to the responsible adviser or logistics provider for the actual transaction.
Keep unpriced optional work visible. Where a buyer must arrange an excluded item, obtain the relevant estimate before treating the proposal as a complete project budget. Record the source and date of each estimate, and keep uncertain amounts separate from confirmed charges.
Finally, send the outstanding questions back as one clarification list. Retain the answers with the updated quotation and brief. The decision record should show the offered scope, remaining dependencies and reasons for selecting a proposal, so procurement and installation teams can work from the same agreement.
