使(shi)(shi)用單位(wei)或經銷商在日(ri)常采(cai)(cai)購中(zhong)使(shi)(shi)用搜(sou)索引擎搜(sou)索生(sheng)產(chan)廠商并購買(mai)產(chan)品已(yi)經成為很多企業(ye)(ye)和經銷商的(de)主要采(cai)(cai)購手段。根(gen)據我們(men)從事(shi)網(wang)(wang)絡營銷的(de)經歷，總結出(chu)以下幾點注意事(shi)項，希(xi)望(wang)能(neng)對采(cai)(cai)購的(de)企業(ye)(ye)起到一些幫助作用。1、采(cai)(cai)購的(de)產(chan)品型號規格、質量標(biao)準(zhun)、技術參(can)數應與(yu)采(cai)(cai)購計劃相符。2、采(cai)(cai)購產(chan)品時，就(jiu)是通過(guo)搜(sou)索引擎搜(sou)索自己需求的(de)產(chan)品，找(zhao)出(chu)生(sheng)產(chan)和銷售該(gai)產(chan)品的(de)企業(ye)(ye)，然(ran)后查(cha)看(kan)該(gai)生(sheng)產(chan)企業(ye)(ye)網(wang)(wang)站是否(fou)經過(guo)其所(suo)在省份工(gong)信廳備案，并登錄查(cha)驗(yan)。3、查(cha)看(kan)該(gai)生(sheng)產(chan)企業(ye)(ye)網(wang)(wang)站欄目配置、欄目內(nei)容是否(fou)足夠專業(ye)(ye)，如大量出(chu)現與(yu)采(cai)(cai)購產(chan)品無關、雜亂無章的(de)，聯系地址標(biao)明xxx工(gong)業(ye)(ye)區、示范園(yuan)而(er)沒有路(lu)牌號的(de)，只(zhi)有手機號碼而(er)沒有固定電話(hua)、傳(chuan)真地的(de)，足可認定該(gai)生(sheng)產(chan)企業(ye)(ye)為非正規的(de)家庭作坊，不宜作為采(cai)(cai)購對象。

一、查驗生產企業資質：1、經過歷年年審的法人營業執照：一般情況下，個體工商戶、個人獨資企業注冊資金低于人民幣五十萬元的即可認定為家庭作坊式廠家。2、雙向爆破聚能管價格具備一般納稅人資格的稅務登記證：企業產品年度銷售額達到或超過一定金額（以稅務發票開具數額為準）并經主管稅務機關核準、具備獨立的開票場所、專職會計及相應的辦稅機具才能升級為一般納稅人企業。3、經過歷年年審的組織機構代碼證：組織機構代碼證是中華人民共和國境內始終不變的法定代碼標識，未經年度審驗的，可視為非法機構。4、國家強制性產品認證證書：一般情況下，所有的電線電纜生產企業只要生產國家強制性產品認證范圍內產品的必須通過國家強制性產品認證（CCC）。專業雙向爆破聚能管依基本常識判(pan)斷，既然單位(wei)名稱(cheng)為(wei)“xxx電線(xian)廠”“xxx線(xian)纜(lan)(lan)廠”，其產品未(wei)(wei)通(tong)過或從(cong)未(wei)(wei)通(tong)過國家強制性產品認(ren)(ren)證(zheng)(zheng)，證(zheng)(zheng)明其硬件(jian)、軟件(jian)設施(shi)及人員配備(bei)根(gen)本達不到一(yi)(yi)個(ge)合格的(de)電線(xian)電纜(lan)(lan)生產廠家應具備(bei)的(de)條件(jian)。5、國際質(zhi)量(liang)體(ti)系認(ren)(ren)證(zheng)(zheng)證(zheng)(zheng)書：ISO國際質(zhi)量(liang)體(ti)系認(ren)(ren)證(zheng)(zheng)是一(yi)(yi)個(ge)企業整體(ti)素質(zhi)、產品質(zhi)量(liang)管理水平(ping)以及服(fu)務水平(ping)的(de)標志(zhi)。6、開戶許可證(zheng)(zheng)。
