Margaret Thatcher is often quoted as saying the trouble with socialism is that eventually you run out of other people's money. Whatever your politics, the point lands. It is easy to spend money that isn't yours, and the public sector offers no shortage of cautionary tales: the government wrote off around £8.7 billion of pandemic PPE, a figure later revised past £9 billion, because much of it was unusable, expired, or worth a fraction of what was paid.
Business doesn't get that luxury. Most organisations answer to someone, whether that's shareholders, trustees, a board, or the bank, and none of them look kindly on money spent without a thought for cash flow. You have to balance the necessary against the nice to have, and make ends meet.
The instinct in most companies is to obsess over the top line. Everything points at winning more sales and lifting revenue, and spending tends to get waved through as long as it feeds the funnel. The bottom line gets far less scrutiny. That is where the savings hide, and it is exactly where a spend approval workflow earns its keep.
What is a spend approval workflow?
A spend approval workflow is the set of rules that decides who can commit money, how much they can commit, and who has to sign it off before anything is ordered or paid. Instead of purchases happening on a nod or a forwarded email, every request follows a defined path: raised, checked against budget, routed to the right approver, then approved or rejected before a penny is spent.
Done well, it puts a named person in the position to say the most valuable word in cost control: no. No, we can get that cheaper elsewhere. No, that isn't in the budget this quarter. No, we don't need the premium tier. Alternatives almost always exist, and an approval step is where someone gets the chance to find them.
How spend approval workflows help you track spend
Approval workflows do more than gate-keep. Because every request passes through the same system, they give you a live, itemised record of what has been committed, by whom, and against which budget, long before the invoice arrives.
- Commitment visibility: see what has been approved and is on its way, not just what has already been paid.
- Budget enforcement: set limits by project, department, or cost centre, and flag or block anything that would breach them.
- Clear accountability: every approval and rejection is logged, so there is a trail showing who authorised what.
- Fewer maverick purchases: off-contract and duplicate buys get caught at the request stage rather than at reconciliation.
Add it up and you move from looking backwards at spend you can no longer change to steering it in real time.
Turn spend approvals on
If you aren't using spend approvals, our advice is simple: switch them on. It is good for the bottom line, and it is one of the first things Zahara is built to do. You decide the rules and the limits, assign approvers and backups, and let the workflow handle the rest, with real-time budgets so nothing slips through unnoticed.
