接收密封投标 — 未到时间，绝不提前开启
供应商通过安全链接提交。其答复保持密封，直至您的委员会记录开标，让公平性由流程设计保障，而非仅依赖制度。
- 答复以密封状态送达：在开标记录完成前，采购方的任何人都无法读取投标，工作区管理员也不例外。
- 逾期投标会自动拒收并通知供应商；截止时间由系统强制执行，而不是由某个人收件箱的时钟决定。
- 草稿和已撤回答复绝不进入评估；评估人员只能看到按时正式提交的内容。
- 开标记录包含时间、出席人员及每份标书的内容，形成经得起复核的审计轨迹。
- 开标后，投标直接进入评分和审批，无需重复录入或导出电子表格。

A response stays sealed until the buyer records the opening — evaluators cannot peek, and late or draft submissions never enter evaluation.
The opening, on the record
Who submitted, when they submitted, which lots they covered and who recorded the opening — kept with the tender for as long as you need it.

Audit trail
Every response keeps its submission timestamp, the opening time and who recorded it — the record stands up to scrutiny later.
Why sealed matters
Procurement rules in most jurisdictions require bids to stay unopened until a formal opening. When the platform enforces it, compliance stops depending on individual discipline: there is no button that opens a bid early, no shared inbox where prices can leak, and no ambiguity about what arrived on time. Suppliers trust the process because the rules are the same for everyone.
