Catch supplier errors before it’s too late.
Upload a supplier order acknowledgement and IBIOS AI compares it against your purchase order automatically. Mismatches in quantity, price, or item code are flagged and a professional query email is drafted for review.
PDF and image formats supported. Line-by-line comparison. British-English complaint email drafted for review.
The acknowledgement that looks fine — until the delivery arrives
A supplier acknowledges your order. Your team glances at it, sees the total looks roughly right, and files it. Weeks later the delivery arrives with an item short and a unit price higher than your quote. The supplier says the ACK showed these figures all along.
They’re right. The discrepancy was there on page two of the ACK. Nobody noticed because checking every line of every ACK against every PO takes time nobody has.
IBIOS is designed to do the comparison for you. The moment a discrepancy is detected, you have a flagged record and a ready-to-send query email. The supplier cannot claim they were never challenged.
From uploaded document to query email, automatically
Three steps that happen automatically after your team uploads the ACK document.
AI document reading
IBIOS reads the supplier ACK document — PDF or image — using AI vision and text extraction. Line items, quantities, prices, and delivery dates are identified and structured for comparison, even on supplier documents that use non-standard layouts.
Line-by-line PO comparison
Each extracted ACK line item is matched against the corresponding IBIOS purchase order line. Quantity, price, item code, and delivery date are compared individually. Mismatches are flagged by type and magnitude so your team can prioritise which discrepancies to query first.
Draft complaint email in one step
The mismatch detection and email drafting happen in a single workflow. Upload the ACK, confirm the mismatches, and a professional British-English query email is ready for review. No copy-pasting figures into a blank email template.
What does a supplier acknowledgement mismatch report look like?
IBIOS presents discrepancies in a clear table so your team can review and decide which to query, all before the email is sent.
Mismatch report — PO-00423 — Supplier: Carron Baths Ltd
Quantity discrepancy — High
Carron Quantum 1700 (SKU CQ1700W)
PO: 2 units → ACK: 1 unit
Unit price discrepancy — Medium
Carron Celsius 1500 (SKU CC1500)
PO: quoted unit price → ACK: higher unit price
Who is supplier acknowledgement checking for?
Any business where supplier ACK errors cost money or cause delivery failures.
Purchasing teams handling high order volumes
Manually checking every supplier ACK is time-consuming and easy to skip when busy. IBIOS automates the comparison so every ACK is checked without exception, not just the ones that get enough attention.
Businesses with multi-line purchase orders
A long multi-line ACK is slow to check by hand and easy to misread. IBIOS compares every line and surfaces only the discrepancies, so your team reviews the exceptions rather than every line.
Operations managers tracking supplier accuracy
ACK mismatch history in IBIOS builds a supplier performance record. Know which suppliers regularly acknowledge incorrectly before it becomes a pattern your team has internalised without realising.
Small teams without a dedicated purchasing function
If one person is managing both sales and procurement, supplier ACK checking is usually the task that gets dropped first. Automating it means it is always done, regardless of how busy the day gets.

Questions about supplier ACK verification
What is supplier ACK verification?
When a supplier acknowledges your purchase order, they typically send a document (PDF or image) confirming what they are supplying. Supplier ACK verification is the process of comparing that acknowledgement against your original IBIOS purchase order to check that quantities, item codes, prices, and delivery dates match. IBIOS automates this comparison using AI — upload the ACK document and the system flags any discrepancy immediately.
What counts as a mismatch?
IBIOS flags four types of mismatch: quantity discrepancy (ACK shows different quantity to PO), price discrepancy (unit price differs by more than the configured tolerance), item code discrepancy (ACK uses a different product code to the PO), and lead time discrepancy (delivery date or lead time differs from what was quoted). Each mismatch type is reported separately so your team knows exactly what to query.
How does IBIOS draft the complaint email?
Once mismatches are detected, IBIOS uses the AI to generate a professional British-English query email addressed to the supplier. The email names the PO reference, lists each discrepancy with the expected and supplied values side by side, and requests confirmation or correction. The draft is stored as a review-ready email in IBIOS — your team reads it, edits if needed, and sends with one click.
How long does ACK verification take?
Document reading and comparison start as soon as the ACK is uploaded. The AI extraction identifies the line items in the supplier document, maps them to your PO records, and generates the mismatch report in a single pipeline run. Longer, multi-page documents take longer to process than a single page.
What formats are supported?
IBIOS accepts PDF and common image formats (JPEG, PNG, WEBP) for ACK documents. Scanned PDFs with clear print are handled by AI vision. Native digital PDFs (supplier-generated, not scanned) are processed with text extraction for higher accuracy. If a document quality is too low for reliable extraction, IBIOS flags it for manual review rather than producing a potentially incorrect comparison.
What happens if the ACK matches the PO exactly?
If no mismatches are found, IBIOS confirms the ACK as verified and updates the supplier order status accordingly. No email is generated. Your team sees a green “Verified” badge on the order record and can proceed with confidence that the supplier has confirmed exactly what was ordered.
