账期谈不下来，价格再低也压现金流。账期和价格一起谈，资金才转得动。
账期压不动，现金流被原料占死
TPE 库存账期是“资金活”：账期、库存、价格。结论先给：账期谈得动，价格留得下——账期，是资金的阀门。
TPE库存账期最大的坑：只压单价不谈账期，资金全压在库存上——账期，是采购的杠杆。
库存是资金关：账期好，资金活。账期差，资金压——库存，是采购的资金题。
账期是资金的杠杆，为什么一起谈
账期缓解资金：先货后款。账期，是资金的缓冲。
账期换价格：账期长价略高。账期，是价格的筹码。
库存要控量：库存压资金。库存，是资金的沉淀。
账期、价格、库存，怎么谈
账期：谈账期长短。账期，是头一筹码。
价格：账期定了再谈价。价格，是第二筹码。
库存：安全库存控制。库存，是第三筹码。
账期谈判，一张表对照清楚
| 条件 | 影响 | 策略 |
|---|
| 账期长 | 资金活 | 争取 |
| 账期短 | 资金压 | 谈 |
| 库存大 | 资金沉 | 控 |
| 用量稳 | 筹码 | 用 |
表格读法：条件按影响排，策略跟着走，账期和单价分开谈。
账期先谈，价格后定。
账长价稳不压款，谈判核这四项
| 项目 | 要求 | 判断 |
|---|
| 账期 | 合理 | 达标 |
| 价格 | 合理 | 达标 |
| 库存 | 可控 | 达标 |
| 资金 | 可担 | 达标 |
表格读法：谈判一项项核，资金看得见，库存周转天数标上。
账期，是资金的阀门。
只谈价格不谈账期，利润压在库里
坑一：只谈价格。单价让了一个点，账期一分没谈下来——账期必谈。
坑二：库存失控。资金压——库存必控。
坑三：账期口头。扯皮——账期写合同。
账期、额度、库存——谈判前问清
三问：什么账期、什么价格、什么库存。一验：合同条款实测——三问一验，供应商底细清楚。
账期验证要先行：先把月结天数和库存周转谈妥，再压单价——账期，是采购的杠杆。
留样要成习惯：每批留样，物性按批次复测。批次换料先对比再放量——批次稳，客诉少。
压款、断供、占资：对照一张表
| 现象 | 原因 | 对策 |
|---|
| 资金压 | 账期短 | 谈账期 |
| 库存大 | 没控量 | 控库存 |
| 价格高 | 没筹码 | 用账期 |
| 扯皮 | 口头说 | 写合同 |
| 断供 | 库存少 | 留安全 |
账期是杠杆，先拿用量当筹码。月用量上吨，账期从月结 30 谈到 60，比硬砍单价更实惠。
账期谈不拢，不是供应商抠，是你没给安全感。把安全库存和滚动预测给他，他才敢放长账期。
口头账期最坑——货卖完了对方催款，合同里却写着现结。账期、价保、调价机制三件事，必须白纸黑字。
库存按周转天数管，别按堆头管。软胶料放久会发粘、硬度漂移，周转超过 3 个月的批次先复检再用。
账期谈顺、滚动预测跟上，资金占用压下来，价格还能再让一档。两头一挤，综合成本比单次砍价低一截。

科隆客户案例：耐油不足溶胀变形，调参数过老化关
宁波一家改性料应用厂，TPE 件耐油性不足，泡油后溶胀变形。科隆配合调整注塑参数（模温/料温/保压），溶胀消除，一次性通过 1000h 老化测试。参数窗口锁死，溶胀从源头断——耐油问题，先看配方再看参数。
小结
TPE库存账期的谈判，账期先谈，价格再定，账期谈得动价格留得下，账期是阀门。
If the payment terms can't be agreed upon, even a lower price will still strain cash flow. Negotiating payment terms along with the price is what truly keeps funds moving.
The payment terms can't be pressured, and the cash flow is completely tied up by raw materials.
TPE inventory accounting period is 'capital liquidity': accounting period, inventory, price. Conclusion first: the accounting period can be negotiated, the price can be maintained—the accounting period is the valve of capital.
The biggest pitfall of TPE inventory payment terms: only focusing on unit price without discussing payment terms, putting all funds into inventory—the payment term is the leverage for procurement.
Inventory is a matter of funding: good payment terms keep funds flowing; poor payment terms tie up funds—inventory is a funding issue for procurement.
The billing period is the leverage of funds, why discuss it together
Payment terms alleviate funds: goods first, payment later. Payment terms are a buffer for funds.
Trade terms for price: Longer terms mean slightly higher prices. Trade terms are a bargaining chip for the price.
Inventory needs to be controlled: inventory ties up capital. Inventory is the sedimentation of capital.
Payment terms, prices, inventory—how to negotiate
Payment terms: Discuss the length of the payment terms. Payment terms are the first bargaining chip.
Price: We'll discuss the price once the payment terms are set. Price is the second bargaining chip.
Inventory: Safety stock control. Inventory is the third chip.
Payment term negotiations, clearly compared in one table
| Condition | Influence | Strategy |
|---|
| Long payment terms | liquid funds | Strive for |
| Short payment term | Capital pressure | Talk |
| Large inventory | Capital is tied up | control |
| Stable dosage | chips | use |
How to read the table: Rank conditions by impact, follow the strategy, and discuss payment terms and unit price separately.
Payment terms are discussed first, and the price is determined later.
Account balances and prices are stable without withholding funds; negotiate and verify these four items
| Project | Requirement | Judgment |
|---|
| Billing cycle | reasonable | Meet the standard |
| Price | reasonable | Meet the standard |
| Inventory | Controllable | Meet the standard |
| Funds | reliable | Meet the standard |
Table reading: Negotiations are checked item by item, funds are visible, and inventory turnover days are marked.
The account period is the valve of funds.
Only talk about price, not payment terms, with profits stuck in inventory
Pitfall 1: Only discuss the price. The unit price was reduced by one point, but the payment terms were not negotiated at all — payment terms must be discussed.
Pitfall 2: Inventory out of control. Money is tight — inventory must be controlled.
Pitfall Three: Payment terms are verbal. Arguing—write the payment terms in the contract.
Payment terms, credit limit, inventory—clarify before negotiating
Three questions: what payment terms, what price, what inventory. One verification: actual measurement of contract terms — Three questions and one verification make the supplier's details clear.
Payment term verification must come first: first negotiate the monthly settlement days and inventory turnover, then push down the unit price — payment terms are the leverage in procurement.
Making sample retention a habit: retain samples for each batch, and re-test the physical properties by batch. Before switching materials between batches, compare them first before scaling up—the batch is stable, and customer complaints are few.
Withholding funds, stopping supply, occupying capital: Compared in a table
| Phenomenon | Reason | Countermeasure |
|---|
| Capital pressure | Short payment term | Discuss payment terms |
| Large inventory | No quantity control | Control inventory |
| High price | No chips | Using the billing period |
| Squabble | Verbal | Write a contract |
| cut off supply | Low stock | Stay safe |
Payment terms are leverage, using the usage volume as a bargaining chip. When the monthly usage reaches tons, the payment terms can be negotiated from 30 days to 60 days, which is more cost-effective than aggressively cutting the unit price.
If the payment terms can't be agreed upon, it's not that the supplier is stingy, it's that you haven't provided a sense of security. Give them safety stock and a rolling forecast, and only then will they dare to offer longer payment terms.
Verbal payment terms are the worst pitfall—after the goods are sold, the other party keeps urging payment, but the contract states cash on delivery. Payment terms, price protection, and price adjustment mechanisms—these three things must be in black and white.
Inventory should be managed based on turnover days, not by stack volume. Soft rubber materials will become sticky and hardness may drift if stored for too long. Batches with a turnover exceeding 3 months should be re-inspected before use.
Negotiate favorable payment terms, keep up with rolling forecasts, reduce capital occupancy, and the price can be lowered one more notch. By squeezing both ends, the overall cost is much lower than a single round of price cutting.
Payment terms are leverage; for monthly usage of over a ton, the terms can be negotiated from 30 days to 60 days. Only by providing the supplier with safety stock and rolling forecasts will they dare to offer longer payment terms. Verbal payment terms are the most risky; the contract should have it in black and white.
Soft rubber materials should be re-inspected after more than three months of circulation before being used again. If stored for too long, they will become sticky and the hardness will drift. If the Shore hardness deviates, the material should be dried first and then the pressure change measured. Inventory is managed according to turnover days, not by pile heads.
Keep up with the rolling forecast according to the agreed payment terms, reduce capital occupation, and the price can still be lowered another notch.
The three things—billing cycle, price protection, and price adjustment mechanism—must be in black and white; when both ends are compressed, the overall cost is much lower than cutting the price in a single instance.
If the billing cycle talks go smoothly, the rolling forecast keeps up, capital occupation is reduced, the price can still be lowered another notch.
Squeezing from both ends makes the overall cost much lower than bargaining just once; the verbal payment terms are the trickiest—after the goods are sold out, the other party urges payment, but the contract states cash on delivery.
The billing cycle is when the leverage first uses consumption as a bargaining chip
For monthly usage in tons, extending the billing period from 30 days to 60 days is more cost-effective than sharply cutting the unit price.
If the payment terms can't be agreed upon, it's not that the supplier is being stingy; it's that you haven't given them a sense of security. Only by providing them with safety stock and rolling forecasts will they dare to offer longer payment terms.
The billing cycle is the leveraged monthly usage, with the tonnage billing cycle extended from 30 days to 60 days.
Only if the suppliers are given the safety stock and rolling forecast will they dare to allow longer credit terms. For soft rubber materials with a turnover of over three months, they should be re-inspected before use, as prolonged storage can cause stickiness and hardness drift.
Cologne Customer Case: Insufficient oil resistance causing swelling and deformation, adjusting parameters led to over-aging shutdown
A modified material application factory in Ningbo had TPE parts with insufficient oil resistance, swelling and deforming after oil immersion. Cologne adjusted the injection molding parameters (mold temperature/material temperature/holding pressure), eliminating the swelling, and passed the 1000-hour aging test in one go. The parameter window was locked down, cutting off the swelling at the source — for oil resistance issues, first look at the formulation, then at the parameters.
Summary
Negotiation of TPE inventory payment terms: discuss the payment terms first, then set the price. If the payment terms can be negotiated, the price can be maintained; the payment terms are the valve.
