In-depth case studies

Warehouse operations at Greenfield Distribution

Greenfield Distribution Ltd

Sector: Third-party logistics, Northampton

Greenfield came to us after losing two major contracts in six months. Their cost-per-parcel had crept up 22% over two years and they could not pinpoint why. We spent three weeks on-site mapping every process from goods-in to final-mile handoff.

The root cause turned out to be a combination of shift-pattern misalignment (night pickers finishing 90 minutes before the first van departed, leaving parcels idle) and a supplier rebate structure that actually penalised higher volumes. We redesigned the shift rota and renegotiated three supplier contracts.

Greenfield re-won one of the lost contracts four months later, partly on the strength of their improved unit economics.

Reception area at Clearview Dental Group

Clearview Dental Group

Sector: Private dental care, five practices across Buckinghamshire

Clearview had grown from one practice to five in four years but profitability had not kept pace. The founder was working 60-hour weeks and still felt behind. Our diagnostic revealed that each practice ran its own booking system, purchasing process, and pricing schedule. No central data existed.

We consolidated booking onto a single platform, standardised the supplier list from 23 vendors down to nine, and introduced a weekly KPI dashboard that the practice managers now review every Monday morning. The founder's working week dropped to 44 hours within three months.

★★★★★
We had been talking about fixing our invoicing process for two years. BizWise Wizards came in, mapped it in a week, and had the new system running in three. Our debtor days went from 58 to 31. I wish we had called them sooner.

★★★★★
The diagnostic alone was worth the fee. They found £140k of annual waste in our procurement that three different internal reviews had missed. The recommendations were specific, costed, and ranked by effort. No vague strategy slides.

★★★★☆
They helped us restructure our pricing across 400 SKUs. Some went up, some went down, and our blended margin rose by 4.2 percentage points in the first quarter. The only reason I am not giving five stars is that I wanted them to stay longer.

★★★★★
I had spoken to two other consultancies before BizWise Wizards. Both gave me a 40-page proposal full of jargon. BizWise sent a two-page summary of what they would do, what it would cost, and what I should expect. That clarity carried through the entire engagement. They rebuilt our reporting in ten days and trained my team to maintain it themselves.

★★★★★
Our sales team had been using three different spreadsheets and a whiteboard. BizWise consolidated everything into a single pipeline tracker, then coached the team on weekly reviews. Close rate went from 18% to 29% in five months. The consultants actually sat in on our sales calls for the first two weeks, which made the advice far more practical than anything we had tried before.

★★★★☆
We brought them in to fix cash flow and they did, but the bigger win was the management dashboard they left behind. For the first time I can see weekly gross margin by product line without waiting for month-end accounts. That visibility alone has changed how we make decisions.
