应付模块中有一个采购订单界面，采购部在签订采购合同后，在正式采购前须在系统的采购订单界面录入订单内容，包括合同号、供应商、材料编码、材料名称规格、价格、数量、到货日期、运输及付款条款等，然后将合同正本交财务部。财务部收到合同正本后对采购订单进行复核，并将合同存档。复核后的采购订单不能修改。系统中的采购订单是用于向供应商订货的单据，其格式和内容是可以编辑的。
在材料到达前采购员在系统中根据采购订单自动生成入库单，并打印出来。一个采购订单可以分数次入库，即可以多次生成入库单，但当数量超过订单限制时，系统将会报警，并将报警信息打印在入库单上。采购员在入库单上签字后将入库单交仓库验收。
仓库验收入库后在入库单上签字，将财务联和采购联交采购员，并在系统中确认过帐，这时入库材料就进入了材料子系统了，公司就可以查询到这笔材料的入库及库存情况。
发票到达后，采购员将发票单据、入库单、申购单等单据整理并粘贴好交财务部入帐。财务部将这些单据核对准确无误后，在系统中生成入库凭证。
二、“暂估入帐”操作
至月末发票单据仍未到达的，财务部就需做“暂估入帐”操作了。
月末财务部将所有单据齐全的童装入库单转为入库凭证，剩下未转为入库凭证的入库单就是要“暂估入帐”的入库单，为稳妥起见，将这些需暂估入库的入库单清单发一份给采购部备查。
通过程序支持，暂估操作是可以自动化的，点击系统中“暂估入帐”按扭，系统自动进行暂估入帐操作。系统在入库单信息上加注暂估标记，在应付帐子系统登记一笔应付款记录，并有暂估标记，同时产生暂估凭证：
借：原材料
其他应收款：暂估进项税
贷：应付帐款——暂估
下月初，将上月“暂估入帐”冲回，产生红冲凭证，此时应付帐子系统记入一笔红冲金额，将上月“暂估入帐”数据冲回，子系统中入库单的“暂估”标记消失，处于未编制凭证状态，材料子系统数量、金额不变。
采用这种材料“暂估入帐”法一方面保证了月末总帐和子系统帐的完全一致，同时材料子系统帐始终和仓库实物数据一致，应付帐子系统明细帐能够反映材料到货和发票到达的实际情况，更重要的是暂估入帐材料的“暂估”价格其实就是采购实价，据此计算的生产成本是完全正确的。
Logistics purchasing warehouse operation process
Cope with modules have a purchase order in the interface, purchasing department after the purchase contract, before the formal purchasing must purchase order interface of the system input order content, including the contract number, name of suppliers, material code, material specification, price, quantity, delivery date, shipping and payment terms, etc., and then deliver the original contracts department.
