Alas, when I first entered the industry, I was also confused - the customer asked "Can I take on the job of LED large-screen in the mall?" and my heart was filled with anger: Where should I take this life? I found out that the agents were 30% paid for advertisements, or they were some leather bag companies selling dog meat with the help of sheep... Today, let’s break this window paper and tell me what people in the industry won’t tell you about the tricks!
1. How deep is the three mainstream channels for relocation?
1. Online order reception platform(Looking at the most convenient pitfalls)
- Advantages: You can see national demand by browsing your phone
- Dark Thunder：
- The platform commission is up to 25% (100,000 projects will be directly eaten up by 25,000 yuan)
- 60% of the bidders are actually subcontractors (it may be a three-hand job to you)
Please give a chestnut: A decoration company has posted a demand for "market LED screen installation". When you arrive, you will find that you have to reinforcing the steel structure at the same time. The budget is not enough. At this time, it is difficult to get a tiger and can only suffer a lot...
2. Industry exhibition/forum(The gathering place for old birds)
- Reliable Index：★★★★☆
- Practical skills：
- Bring a good case video to store (on-site direct screen projection display)
- Focus on booths with government background (this type of project payment is fast)
- When exchanging business cards, mark "Emergency orders can be accepted" on the back (many Party A is temporarily short of people)
3. Government Tendering Network(Novices are careful to enter)
- Data Talk：
| Project Type | Margin ratio | Advance Cycle | Profit ratio |
|---|
| Municipal Image Project | Starting from 20% | 180 days after acceptance | 8%-12% |
| Commercial complex project | 10% | 90 days after acceptance | 15%-18% |
Lessons of blood and tears: Last year, a colleague took on a cultural and tourism project. During the acceptance, Party A insisted on installing an intelligent sensing system. The contract was not clearly stated, and finally paid 70,000 yuan to pass the test...
2. Five details of identifying reliable Party A
-
View the tender documents：
- Write clearly that "including 3 years of maintenance" is more reliable than "package installation only"
- Requires "waterproof level IP65" to write "outdoor screen" professionally
-
Check the project site：
When you arrive at the construction site, do three things first:
- Use a distance measuring instrument to measure the height of the installation point (to prevent the crane fee from being calculated less when quoting)
- Check the load of the power supply line (don't wait until the installation is finished and the screen cannot be moved)
- Take photos of the surrounding environment (you should pay special attention to the visual distance and angle on the advertising screen)
-
Ask acceptance criteria：
When you encounter a party like this, you should withdraw quickly:
❌ "Just the brightness is about the same" (must need to be adjusted repeatedly)
❌ "The renderings are for reference only" (if you are not satisfied with the actual work, you have to rework)
-
Snap payment terms：
If the down payment is less than 30%, don’t accept it! The most deceptive contract I have ever seen says "Full payment after passing the acceptance", but Party A delayed it for two years without acceptance, and the construction team could not afford the salary...
-
Check Party A’s qualifications：
Three essential certificates:
✔ Advertising license (necessary for commercial screens)
✔ Electricity approval documents (outdoor large screen power exceeding 50kW must be approved separately)
✔ Fire safety commitment letter (especially the screen installed in the shopping mall atrium)
3. The mistakes that 90% of newcomers make when quoting
Bill of Materials Leaks TOP3：
- Lightning protection grounding device (must be installed on outdoor screens, one set costs 8,000)
- The cooling system upgrade fee (Party A temporarily requires 24 hours to start the machine)
- Special-shaped structure reinforcement fee (hidden cost of arc screen and wavy screen)
Misconceptions about labor cost calculation：
- Don’t simply press "yuan/㎡" for quotation! Installing a 10-meter high screen and a 3-meter high screen with a working time difference of 3 times
- Late-night construction fees must be negotiated in advance (the shopping mall usually only provides construction windows from 2-5 am)
Equipment rental trap：
- Market price of high-altitude working vehicles:
| Car model | Daily rental price | Suitable for scenes |
|---|
| 18-meter curved arm truck | 2200 yuan | Store installation along the street |
| 30m spider car | 6,800 yuan | Shopping Center Atrium Operation |
| 50-meter tower crane | 12,000 yuan | Sports Venue Project |
Key reminder: The contract must state that "the equipment failure is not responsible for delays." Last year, a car rented by the team broke down on a typhoon day, and Party A forced a deduction of 20,000 yuan for the extension fee...
4. The truth that the editor has realized after trampling on the pit
-
Don't believe "This loss will be compensated for next time"——A shopping mall manager said that there are still 5 screens to be installed in the future, but the final payment of the first screen was not settled. This kind of person is a professional cake painting user
-
Must include grayscale test diagrams during acceptance——A party said the color was uneven during the acceptance of a project, so he took out the test data and shut up immediately. This trick saved at least 30,000 yuan in rectification costs.
-
It is better to bet on the acceptance form than to leave a 10% warranty?——The smartest way I have ever seen is: leave 5% of the final payment and sign the "no legacy problem confirmation letter" for Party A, which is much more effective than betting.
-
Build your own technical archive——Remain every item:
- Brightness debugging parameters (accurate to different time period settings)
- Cable wiring diagram (no need to remove the ceiling for next repair)
- Core component batch number (you can also contact the supplier to repair it after the warranty)
After all, taking on the job of large LED screens is like fighting guerrilla warfare - you must understand the technical parameters and be able to read the dishes. Next time I meet a Party A who has a price of 30% lower than the price, and directly slapped the construction specifications on the table: "The price you want can only be IP54 waterproof. Don't ask me if it is leaking when it rains." Ensure he will re-negotiate honestly!
