Founder note
I built this because I needed it
I have spent eight years building a drinks brand from Glasgow. Nobody gave us money to do it, so every penny of margin was ours to find or lose.
Somewhere around year five I sat down and audited what we bought. Not ingredients, which we watched closely, but the boring stuff around them. Cases. Labels. Pallet wrap. Haulage. Waste collection. Gloves. Around forty lines, most of them set up in the first year and never looked at since.
Some of what I found was suppliers who had raised prices quietly on an invoice and never mentioned it. Some of it was lines that had never been tested at all, because we picked someone in year one when we had bigger problems.
It took a fortnight of evenings. Finding suppliers who would quote at our volumes. Writing the same enquiry twelve times. Chasing the eight who did not reply. Then building a spreadsheet that could tell me whether one price actually beat another once you accounted for the minimum order and the delivery charge.
I found the money. And then I never did it again, because I had a business to run.
That is the whole problem, and it is why this exists.
A penny is not a small number
Here is the thing that changed how I thought about it. We make a drink. Take a penny off what it costs to produce one unit and, at the volumes we run, that is thousands of pounds a month. Not once — every month, for as long as the price holds.
A penny sounds like nothing. It is the sort of figure you would not get out of bed for on a single invoice. Multiply it by everything you make and it is a salary.
Money found is worth more than money earned
The other half of it is arithmetic that took me embarrassingly long to internalise. Money you stop spending goes straight to the bottom line. Money you earn has to get past the cost of earning it first.
If your net margin is 10%, then a thousand pounds a year off your input costs is worth the same as ten thousand pounds of extra sales. If it is 5%, it is worth twenty thousand. And the ten thousand of extra sales needs marketing, stock, delivery and someone to handle it — while the thousand off your costs needs one email.
I am not suggesting you stop growing. I am saying that most small businesses put every hour into the harder side of that equation and almost none into the easier one.
Growing means you can ask for more, but you have to ask
When you buy more, better pricing exists. Suppliers have price breaks, and they are real. What almost never happens is somebody at your supplier noticing you have grown and offering you the better rate unprompted. Their price list is not going to phone you.
So the price you agreed when you were ordering ten pallets a year is very often still the price you are paying at forty. That is not sharp practice. It is that nobody on either side is watching for it. CostSpring watches your volumes as well as your prices, and tells you when you have grown into a conversation worth having — including which suppliers could not quote you before and now can.
What that means for how it is built
I am the person this is for, which decides most of the arguments. It does not send anything to a supplier that you have not read, because I would not hand my supplier relationships to software either. It never claims a saving, because I know what it feels like to be sold a number. It tells you where a figure came from, because the first thing I did with any number in my own audit was try to check it.
