This series uses Dingli, a Patisco demo account. Every system screen and all the data shown here came from real operations in the system, including the exchanges between buyers and suppliers; they are not mock-ups. The people and dialogue are dramatized, and the illustrations are for illustration only. Screens are shown in the system's Chinese interface; Patisco is also available in English and other languages.
In the story: The first Thursday after the fair, 7:40 a.m.
One extra line
Jonas had already accepted Dingli's invitation and had his own account. He didn't write back. He edited his PI directly and clicked send.
The quantity changes, A-Zhe had expected. The extra line was a set of BB axles, "while we're at it." But A-Zhe stared at the unit price column for a long time, sure that something was off.
He finally found it: the chain's unit price was down by 0.3.
Not a typo. While changing the quantities, Jonas had changed one more cell and said nothing about it.
A-Zhe asked in the discussion. Jonas replied: "You said it was OK at the fair."
What A-Zhe had said at the booth was "same price as last year." He was sure of it.
How it used to go
This kind of thing used to come down to eyesight. A customer would copy the last version of the PDF or Excel file, edit it, and send it back.
A-Zhe would put the version he'd sent next to the version that came back and compare them line by line. Then he'd do it again. If he caught something, the argument came next: "You said it was OK." "I never said that." Both sides would dig through emails and notes from the fair, hunting for proof.
And if he didn't catch it? On reconciliation day after shipping, Hsiu-Chin would notice the chain total was short, by which point the goods were already at sea.
How it goes in Patisco
Originals and copies
One concept first. In Patisco, the PI A-Zhe issues is the original, and what Jonas receives on his side is an automatically generated copy. They share a number but are independent: Jonas edits his, and A-Zhe edits his.
When Jonas finishes editing the copy and clicks [Send], A-Zhe sees it on his side. (If the customer has no account, it's the kind of proxy copy from #8: a record of what they sent, word for word.)
Document 101｜Change records: From the day an order is issued to the day it's final, it often goes back and forth several times: quantity, unit price, delivery date, items. Who changed what, and when, is the change record. When an argument starts, neither side needs the louder voice. They need this record.
The changed cell gets marked
This time, Jonas made his edits in the system. A-Zhe opens PI-0411. The header says [Your turn to reply], and [Compare changes] has turned orange: "Changes from the other side — compare."
He opens the comparison. On the left is the version from the moment Jonas clicked send; on the right is A-Zhe's. The quantity changes, the extra line of BB axles, and the chain price down by 0.3 are all marked, all three places. No lining up PDFs, no second pass.
A-Zhe deals with them one at a time. Quantities: [Use their value]. BB axles: [Accept the addition]. Chain unit price: not accepted, stays at the original price. Then he clicks [Send] with one line attached: "Chain price stays as agreed at the fair. Same price as last year."
Before you argue, check the record
No digging through fair notes this time. Every version is in [Change history]: v1, the one A-Zhe first sent, has the chain at the original price, and the edited version shows Jonas clicked send on it himself. Each version can be opened with [Preview PDF].
A-Zhe didn't write a long email. He replied with one line, and Jonas didn't argue further.
That afternoon, Jonas clicked [Confirm] on his side. The PI-0411 header changed to [Confirmed by both].
Where can AI help?
If the company has turned on its AI settings, the comparison screen also has an [AI suggestions] button. It reads the differences between the two sides, offers three or four directions for a response, such as "accept the quantities, decline the price cut," and fills the suggested numbers into your draft.
But AI only fills in the draft. It won't send for you, and it can't change currency, trade terms, or specs. The one clicking [Send] is always a person.
Before vs With Patisco
| Before | With Patisco | |
|---|---|---|
| What the other side changed | Two PDFs side by side, line by line | The comparison screen marks what changed |
| How you respond | Edit your own Word file and resend | Accept or decline item by item, then [Send] |
| "You said it was OK" | Dig through emails and notes for proof | Every version is in the change history |
| If you miss it | You find out on reconciliation day | The changed cell is visible the moment they send |
A word for the boss: Changes to an order used to get worked out quietly, and who agreed to what lived in people's memories. Now every change is a record.
That evening
With that settled, Chairman Lin was in a great mood and started a group order for hand-shaken tea, the Taiwanese office ritual.
Hsiu-Chin was taking everyone's orders and stopped by A-Mei's desk. "The usual? No sugar, no ice?"
"I'd better make it warm," A-Mei said. "The doctor says to go easy on cold drinks."
Hsiu-Chin nodded and, without missing a beat, said, "Makes sense. When are you due?"
"End of May."
The office went silent for two seconds.
A-Zhe turned around. "...Due for what?"
Chairman Lin's teacup stopped in midair. "A-Mei, you're... since when?"
A-Mei looked at the two men, then at Hsiu-Chin, and sighed. "I've been wearing two jackets. You two really didn't notice?"
Hsiu-Chin patted A-Zhe on the shoulder. "You can spot Jonas changing a price by 0.3, but not this?"
"The system flagged that one for me!"
