When I first entered the industry, I was looking for work everywhere like a headless fly - just like a novice who searched for "how to quickly receive an LED installation project" and was defrauded of the deposit by an agency. This industry is very deep, and today I will help you peel away the surface and look at the essence, and talk about the pitfalls that I have encountered over the years and the ways that I have learned.

Comparison of the three mainstream job acceptance channels

A shopping mall exterior wall project last year is a typical case. The general contractor posted a budget of 3 million on the bidding platform, and after seven bids, the transaction price was reduced to 2.1 million. The winning bidder cut corners and used second-hand modules. As a result, the brightness did not meet the standard during acceptance and was deducted 800,000 yuan. So,​ ​Public bidding projects often hide price traps​​。

Five characteristics of reliable channels

1. The demander provides CAD drawings of the site (at least 1:50 scale)
2. Advance payment ratio ≥ 30% (material procurement is guaranteed)
3. The contract clearly states the acceptance criteria (for example, grayscale level ≥ 16 bit)
4. Technical briefing meeting and on-site inspection (to avoid wrangling afterward)
5. The warranty deposit shall not exceed 5% (to prevent difficulty in collecting the final payment)

Here’s a trick: when it comes to projects that require the use of specific parameters (such as refresh rate ≥ 1920Hz), 80% of them are contracted by professional organizations. Although such projects have strict requirements, they rarely default on project payments. Last year, an e-sports stadium project even settled the final payment in advance.

Guide to accepting jobs and avoiding pitfalls

● Be wary of "fully-advanced" projects: especially those that require the use of imported lamp beads without showing the purchase voucher.
● Be careful with "relationship orders": Don't accept anyone who greets you from your boss but doesn't confirm it in writing.
● Stay away from the "three no's" demands: no technical specifications, no acceptance standards, and no advance payment.

Lessons from blood and tears: A certain county gymnasium project promised to use rental screens, but during the acceptance check, Party A insisted on changing to fixed installations. Because the contract was not written clearly, the disassembly and assembly fee alone was 120,000 yuan. When signing a contract, it must be stated: "Changes in installation methods require a separate supplementary agreement."

Tips for accepting jobs in special situations

​​commercial complex​ ​: Focus on the traffic data (a daily average of more than 10,000 times requires a high refresh rate)
​​stage acting​ ​: The power supply load must be confirmed (three-phase power access is a hard indicator)
​​sports venues​ ​: Focus on waterproof and shockproof design (the Premier League stadium standard is level 9 shockproof)

Last year, we took over a project for a seaside music festival. Because we did not consider sea wind and salt spray corrosion, color patches appeared on the screen within two days. Later, I switched to coating modules to pass the test. This taught me:​ ​Environmental suitability is more important than parameters​​。

Editor’s opinion: Instead of casting a wide net to receive orders, it is better to delve deeply into specific areas. Next time you see a project with "government background" or "central enterprise investment", first check the owner's payment records for previous projects. Remember, any supplier that dares to write "three years of free maintenance" in the contract must have solid technical confidence.
