Your suppliers make mistakes. Margn catches them.
Margn checks every line of every supplier invoice against what you paid before, what you agreed, what you ordered and what your other sites pay. Then it tells you, in plain English, what you were overcharged and how to get it back.
Read-only. Margn never changes your accounts or pays anything.
Price up 10.8% on Full cream milk
Meadowlark Dairy Supply · Ponsonby
Cost on this invoice
$14.80
Charged $2.05/L ex GST. You were paying $1.85/L on your last three invoices. That cost an extra $14.80 on the 74 L delivered.
$10,400 a year
is what a 5% price creep costs on $4,000 of weekly supplies.
Every line, every time
Nobody has time to check 40 invoices a week by hand. Margn does it as they arrive.
Ex-GST unit prices
Compared per kg, per litre or each, so a new pack size can't hide a rise.
Seven checks on every invoice
Each flag comes with the evidence: the earlier prices, the agreed price or the other supplier's price, and exactly how much it cost you.
Price creep
Spots sudden jumps and the slow 2% rises that add up to 10% by winter.
Above your quote
Holds suppliers to the prices you agreed, for the dates you agreed them.
Order mismatches
Billed for 10 kg when you ordered 8? Charged for something nobody asked for?
Site price gaps
Finds when one of your sites pays more than another for the same thing.
Cheaper suppliers
Shows where another supplier already sells you the same item for less.
Maths and GST errors
Line totals that don't add up, and GST added on top of GST-inclusive prices.
Duplicate invoices
Catches the same invoice entered twice before it gets paid twice.
Monthly savings report
What was found, disputed and recovered, ready to share with your accountant as CSV or PDF.
How it works
- 1
Connect Xero or drop in invoices
Margn reads your supplier bills from Xero, or you upload PDFs and CSVs. Read-only, always.
- 2
Every line gets checked
Unit prices are turned into $/kg, $/L or $/each, ex GST, and compared with your history, your quotes and your other sites.
- 3
You get the money back
Each flag says why it was raised and what it cost. One click writes a polite email to the supplier with the evidence.
Advisory and read-only by design. Margn reads bills from Xero with read-only permissions. It never edits, approves or pays an invoice. You decide what to do with every flag.
Simple pricing
We're in pilot with a handful of venues. Final pricing is being set with them.
