二、采购合同的内容
合同具有法律效力，合同上规定签约者应履行和应获得的权利和义务(不能列入与法律相抵触的条款)，受到国家法律的承认、维护和监督，违反时要受到法律的制裁。因此，签订合同既是一种经济活动，同时也是一种法律行为，经济合同制是管理经济的一种有效的经济办法，也是一种依据法律办事的法律办法。
签约双方之间达成的一致意见的各项条款构成经济合同的内容。经济合同的内容一般包括：合同的标的，标的数量和质量，价款和酬金，履行的地点、期限和方式，违约责任，合同附则与签署等。因此，零售企业采购合同的条款，应当在力求具体明确，便于执行，避免不必要纠纷的前提下，具备以下主要条款：

(二)商品的质量和包装
合同中应规定商品所应符合的质量标准，注明是国家或部颁标准；无国家和部颁标准的应由双方协商或凭样订(交)货；对于副、次品应规定出一定的比例，并注明其标准；对实行保换、保修、保退办法的商品，应写明具体条款；对商品包装的方法，使用的包装材料，包装式样、规格、体积，重量、标志、及包装物的处理等，均应有详细规定。

1．不按合同规定的商品数量、品种、规格供应商品。
2．不按合同中所规定商品质量标准交货；
3．逾期发送商品。购买者有逾期结算货款或提货，临时更改到货地点等，应付违约金或赔偿金。
(七)合同的变更和解除的条件
合同中应规定，在什么情况下可变更或解除合同，什么情况下不可变更或解除合同，通过什么手续来变更或解除合同等。
此外，采购合同应视实际情况，增加若干具体的补充规定，使签订的合同更切实际，行之有效。
三、采购合同的签订
(一)签订采购合同的原则
零售企业签订采购合同，必须遵循法定的原则：
1．合同的当事人必须具备法人资格。这里所指的法人，是有一定的组织机构和独立支配财产，能够独立从事商品流通活动或其他经济活动，享有权利和承担义务，依照法定程序成立的企业。
2．合同必须合法。也就是必须遵照国家的法律、法令、方针和政策签订合同，其内容和手续应符合有关合同管理的具体条例和实施细则的规定。
3．签订合同必须坚持平等互利，充分协商的原则。
4．订合同必须坚持等价、有偿的原则。
5．当事人应当以自己的名义签订经济合同。委托别人代签，必须要有委托证明。
6．采购合同应当采用书面形式。
(二)签订采购合同的程序
签订合同的程序是指合同当事人对合同的内容进行协商，取得一致意见，并签署书面协议的过程。一般有如下五个步骤：
1．订约提议。订约提议是指当事人一方向对方提出的订立合同的要求或建议，也称要约。订约提议应提出订立合同所必须具备的主要条款和希望对方答复的期限等，以供对方考虑是否订立合同。提议人在答复期限内不得拒绝承诺，即提议人在答复期限内受自己提议的约束。
2．接受提议。接受提议是指提议被对方接受，双方对合同的主要内容表示同意，经过双方签署书面契约，合同即可成立。也叫承诺。承诺不能附带任何条件，如果附带其他条件，应认为是拒绝要约，而提出新的要约。新的要约提出后，原要约人变成接受新的要约的人，而原承诺人成了新的要约人。实践中签订合同的双方当事人，就合同的内容反复协商的过程，就是要约——新的要约——再要约——……直至承诺的过程。
3．填写合同文本。
4．履行签约手续。
5．报请签证机关签证，或报诸公证机关公证。有的经济合同，法律规定还应获得主管部门的批准或工商行政管理部门的签订。对没有法律规定必须签证的合同，双方可以协商决定，是否签证或公证。
四、采购合同的管理
零售企业为了保证采购合同的履行，保证企业购销任务的完成，必须加强对合同的管理工作。从零售企业的角度来看，采购合同的管理应当做好以下几方面的工作：
(一)加强采购合同签订的管理
加强对采购合同签订的管理，一方面是要对签订合同的准备工作加强管理，在签订合同之前，应当认真研究市场需要和货源情况，掌握企业的经营情况、库存情况和合同对方单位的情况，依据企业的购销任务收集各方面的信息，为签订合同、确定合同条款提供信息依据。另一方面是要对签订合同过程加强管理，在签订合同时，要按照有关的合同法规规定的要求，严格审查，使签订的合同合理合法。
(二)建立合同管理机构和管理制度，以保证合同的履行
企业应当设置专门机构或专职人员，建立合同登记、汇报检查制度，以统一保管合同、统一监督和检查合同的执行情况，及时发现问题采取措施，处理违约，提出索赔，解决纠纷，
保证合同的履行。同时，可以加强与合同对方的联系，密切双方的协作，以利于合同的实现。
(三)处理好合同纠纷；
当企业的经济合同发生纠纷时，双方当事人可协商解决。协商不成时，企业可以向国家工商行政管理部门申请调解或仲裁，也可以直接向人民法院起诉.
(四)信守合同,树立企业的良好形象
合同的履行情况好坏,不仅关系到企业的经营活动的顺利进行,而且也关系到企业的声誉和形象.因此,加强合同管理,有利于树立良好的企业形象.
