You agreed the price. You didn’t agree the date.
A supplier rarely touches a price you negotiated. What moves is everything else — the delivery date slips two weeks, the quantity comes back short, a line is missing altogether — and it moves on the order confirmation, after you have already committed. OrderDiff reads every confirmation against your order and tells you what changed, worst first.
Free to try. Upload an order and a confirmation — no ERP connection, no IT ticket, nothing to install.

The problem
The confirmation is where your order quietly changes.
You raised the order from an agreed quotation, so the price is settled. Then the confirmation comes back and the delivery date has moved, the quantity is short, or a line is simply not there — and there is no workflow anywhere that makes anyone read it.
The change is buried
The confirmation looks like the order. The one line where the date moved is line 14 of 30, in a column you skimmed.
It arrives when you are busy
Confirmations land as attachments among forty other emails, days after you raised the order and stopped thinking about it.
Nobody checks every one
Reading two documents line by line takes ten minutes. Multiply by the orders you raise in a week and it stops happening.
Your ERP never sees it
The confirmation stays in the mailbox. The order in your system still says what you asked for, not what the supplier agreed to.
A line stops
The delay was on the confirmation in March. You found out when the material did not arrive in April.
You are short
You ordered 500 and the supplier confirmed 400. Too late to source the rest anywhere else.
A line vanishes
Four of your five lines came back confirmed. The fifth was never mentioned again by anyone.
And sometimes the price
Rarer, because you agreed it at quotation — and the most expensive one to miss when it does happen.
How it works
From an attachment to an answer
No setup, nothing to connect, no learning curve. If you can forward an email, you can check an order.
01
Get the documents in
Upload an order and a confirmation, or forward the confirmation to your workspace address and let it run on arrival. Excel or CSV, whatever your columns are called.
02
Every line matched
Lines pair by item code, by your supplier’s own code, or by description — then quantity, price, unit, and delivery date are compared one line at a time.
03
Worst first
A dropped line and a two-week delay come first, each with what it costs you in money or in days. Anything it could not match confidently is shown rather than skipped.
04
Take it to the supplier
Export the findings, send them back to the supplier, and keep the check — so a supplier who slips every month has a record of it.
Results
Built around one question: what needs my attention?
Instead of another line-by-line report, OrderDiff ranks every change by how serious it is — so you review what matters first.

Automation
Coming to automated workflows
The manual flow you start with is the foundation for something bigger. Teams will eventually connect their procurement systems and let OrderDiff watch confirmations automatically — flagging only the orders that need attention.

Getting your documents in
Nothing to connect, nothing to install
Two documents have to reach us: the order you raised and the confirmation the supplier sent back. Both already move as email attachments and spreadsheet exports — so that is what this reads. No API, no vendor review, no waiting on IT.
- Works today
An address to forward to
Your workspace gets its own email address. Forward a confirmation to it, or ask the supplier to Cc it, and the check runs the moment it arrives.
- Works today
Your open-order export
The open-order report your system already produces, dropped in as a file. That is what confirmations get compared against.
- Works today
That export, on a schedule
Most systems can email a saved report every morning. Point it at the same address and your order list keeps itself current.
- On request
A direct connection
Straight into SAP, NetSuite, Odoo, ERPNext or Microsoft Dynamics. Built for a customer who needs it — the three above cover the same ground without a project.
If a direct connection to your ERP is the one thing standing between you and using this, say so and we will build it.

FAQ
Questions, answered honestly
OrderDiff is being built in phases. Here is exactly where things stand.
What files can I upload?
Purchase orders and supplier confirmations as Excel (.xlsx, .xlsm), CSV or PDF. PDF is not supported yet — if your supplier sends confirmations as PDF, get in touch and send us one.
We agree the price at quotation. So what is left to compare?
Price, usually nothing — and that is the point. What changes on a confirmation is the delivery date, the quantity, the unit of measure, or whether a line appears at all. A supplier who accepted your price can still come back with 400 instead of 500, or the 30th instead of the 16th, and nothing in your ERP will tell you. Those are the deviations this catches. Price is the rare one, and the expensive one when it happens.
How do confirmations get in?
Two ways, and both work today. Upload the order and the confirmation and get an answer immediately. Or forward the confirmation to the address your workspace is given — or ask the supplier to Cc it — and the check runs on arrival, with the result emailed to whoever should see it.
Does this require an ERP?
No, and it never connects to one. It reads two things: the confirmation your supplier emails, and an export of your open orders — the open-order report every system can produce. Reading a file needs no access to the system that made it, no API, and nothing installed.
Can I try it for free?
Yes. The free product lets you upload a purchase order and supplier confirmation and see exactly what changed. No credit card required.
Will you connect directly to SAP, Odoo, NetSuite?
Only for a customer who needs it and has said so. It is deliberately last on the list, because the file export and the email address already cover the same ground with no project, no vendor review, and no waiting on your IT team. If a direct connection is the thing standing between you and using this, tell us and we will build it.
Does OrderDiff automatically change or approve my orders?
No, and it is not an approval workflow. It reports what differs between your order and the supplier confirmation, ranked by what it costs you. It never accepts, rejects, modifies or sends anything on your behalf. What to do about a two-week delay is your call, and it stays your call.
What if it is not sure about a line?
It says so, in the queue, rather than deciding quietly. A line it cannot confidently match, a column it read two ways, a price it could not parse — each one is shown with what it was read from and how certain it is. A missed change is expensive; being told to look at something is merely mildly annoying, and the product is built around that trade in that direction.
