The first is to do a decade of quotation information of China Building Materials Online. Between the LZ than my age are big, do very early. Advantage is that the amount of information is very large, the accumulation of ten years of information resources is really not cover, the bottom of the box of information can be found. Also presented cost station out of the standard price of the booklet, although the booklet on the price of the national standard, no specific brand, the general bottom of the cost of material search basically can not be used, but if the company in the future and the A party have any dispute, this is a more powerful reference basis.
And the disadvantages of building materials online, it is also too long. So huge information resources, the chance of error is also very considerable. I remember LZ I once took a theme hotel project, because the A side of the material price requirements are very detailed as well as strict, it is difficult to find materials to meet the requirements of the A side, the price is very suitable, take over the even hit the past when the proof, was told that people in 08 years do not do this line. Then LZ repeatedly looking for, begged acquaintances, played n long-distance, only to find the price and brand are to meet the requirements of the material.
Another old-fashioned product is Quanta. This is selling software, not selling information, so the software is very easy to use. You can find the material statistics in a table, summary statistics, very easy to use. Then buy the software at the same time, the gift of building materials price information, of course, the gift of the product is poor, the information is not accurate enough is also an important drawback of Quanta.
WiseNews, may not be as long ago as the first two. However, Wisepac belongs to the Ruida Heng also has a history of five or six years, do engineering information originated Wisepac has a huge material enterprise members. The amount of data may not be as building materials online as the Yellow River flooding unceasingly, but the accuracy is really no say, although can not be used as the final standard of material procurement, but is definitely the cost assessment of the tool. Let me feel more convenient place, is the classification of their product search form, that is and jingdong classification is the same way, e-commerce site classification of standard international examples, is also the most detailed classification of all products. As for all the main manual query link, of course, there is a huge number of member companies of the Wisdom Network is better.
Because of the advantage of manual search, the disadvantage of Wisers is also inevitable! That is, the price is more expensive, a year's membership fee is more expensive than other products.
Next is the cost pass, the people love and hate the enemy. Guangdong counterparts mentioned is a mixed bag of flavors ah! It is very specialized, the product is limited to the local Guangdong, whether it is a material offer or for the customer, a small range of product accuracy is naturally higher, but it is said that this product is forced to buy, the reason is naturally unspeakable. If the field project to do a lot of units, had to buy another other products, inexorable secondary consumption.
There is also easy to talent network, was building materials online acquisition of the Shanghai platform, the advantages and disadvantages and building materials online as the same.
Luban software, and Guanglianda, the same, winning in the software, the accuracy and coverage of the specific material quotes will be a little lost.
These software down really can be compiled a costumer inquiry sour history. Personal views may be biased, but take out a little sigh, and Jun **** encouragement only.
