Most reusable packaging business cases fail in the meeting rather than in reality – not because the project is bad, but because the numbers were optimistic in ways a finance reviewer can spot immediately. Three questions come up every time, and having honest answers to them is most of the work.
Question one: what is the baseline
What do you spend today, per year, on the packaging being replaced – all in, including disposal and the labour of handling it. This number is usually larger than the purchase line suggests, which helps you, and it has to be defensible.
Pull it from purchase records rather than estimating. If the spend is spread across sites or buried in a general packaging line, say so and say how you apportioned it. A reviewer will accept an estimate that is documented and reject one that is not.
Question two: what is the trip count, and how do you know
Every reusable case rests on this. If your number came from a supplier’s marketing, it will not survive. If it came from a pilot you ran, with a count and a loss rate, it will.
Present a range rather than a point, and use the bottom of it. A case that works at the pessimistic end of the range is a case that gets approved; one that only works at the optimistic end gets another meeting.
Question three: what is the capital and when does it come back
Packaging fleets are usually expensed rather than capitalised, but either way the reviewer wants the payback period – spend divided by annual saving. Under a year gets approved easily. Two years needs a supporting argument. Beyond that you are asking for a strategic decision rather than a financial one, and should present it as such.
Three things to leave out
Savings you cannot invoice. If a benefit does not show up as a reduced line or a avoided cost, do not put a number on it. Mention it as a qualitative benefit and move on.
Sustainability benefits framed as cash. Real, and often the reason the project is happening – but converting them into a financial saving invites exactly the scrutiny you do not want. Keep them separate.
Every cost saving at once. A case that claims savings in materials, labour, transport, damage and storage simultaneously looks padded even when each line is true. Pick the two largest and defend those.
What to include instead
The assumptions, in writing, with a named owner for each. A pilot plan with a defined success threshold. And what happens if it does not work – which reviewers trust far more than a case that has no downside.
Consumption estimates for sheet are covered in estimating monthly sheet consumption.
The pilot threshold, concretely
One number, agreed before the pilot, that decides the next step. Return rate above a percentage, damage rate below one, or cost per trip under a figure. Write it down, name who measures it, and set the review date when the pilot starts rather than when it finishes.
A threshold converts an argument into a measurement, and it is the reason pilots get approved. It also protects you: a project that fails against a threshold you set is a project that failed honestly.
How to present a range
Give three cases – pessimistic, expected, optimistic – and recommend the decision that the pessimistic case supports. Reviewers trust a case that works at the bottom of its own range, and they discount one that only works at the top.
Name the assumption behind each case. Assumptions without owners are the first thing a reviewer attacks.
What we can do
We supply PP corrugated sheet and will give you our trip-count and loss-rate assumptions in writing, on our letterhead, for your file. Send us your current annual spend and we will build the comparison – using the conservative end of the range, not the flattering one.
