The handover gap: where margin quietly disappears in project businesses

Ask most operators where their margin goes, and they'll point to the obvious suspects. A bad quote. A difficult client. A labour overrun. A supplier blowout.

Those things happen. But they're rarely the full story.

In my experience, the single most expensive part of a project business isn't the quoting, the delivery, or the invoicing. It's the space between them.

The handover gap.

What the gap actually looks like

Sales wins the job based on a set of assumptions — scope, timeline, inclusions, exclusions, pricing logic. Some of that is written down. Much of it lives in the salesperson's head.

Delivery starts the job based on what's been handed over. If the handover is thin, the project manager fills in the blanks. Sometimes correctly. Sometimes not.

Finance invoices the job based on what delivery tells them. If delivery didn't flag a variation, finance doesn't know to bill it. If scope expanded informally, the invoice still reflects the original contract.

Three functions. Three different versions of the same job. And no structured point where they reconcile.

Why this leaks margin in ways owners don't see

The margin loss from a handover gap rarely shows up as a single bad number. It shows up as a slow drift.

Variations that were done but never priced. Scope creep that was absorbed because nobody noticed in time. Invoicing that lagged because delivery didn't sign off. Final accounts that came in 5–8% below what was forecast — and nobody could quite explain why.

Individually, each one looks small. Collectively, they're the difference between a good year and a great one.

The root cause isn't people

This is where owners often go wrong. They assume it's a performance problem — the salesperson didn't brief properly, the PM didn't flag the variation, the admin didn't chase the paperwork.

Sometimes that's true. More often, it's structural. There's no defined moment in the workflow where sales, delivery, and finance are required to align on the same job, on the same terms, at the same time.

Without that moment, the gap is inevitable. It doesn't matter how good your people are.

What fixes it

Three things, in order.

First, a formal handover point between sales and delivery — not a forwarded email, but a structured exchange where scope, assumptions, and commercial terms are confirmed and understood.

Second, a live variations process that sits inside the job, not outside it. The moment scope changes, the commercial change is captured and priced. Not at month-end. Not at the final invoice. At the point the change happens.

Third, a regular reconciliation point where delivery and finance sit over the same job and confirm what's been done, what's been billed, and what's outstanding. Weekly for active jobs. Not monthly.

The shift this creates

Businesses that close the handover gap don't just recover margin. They change how the whole organisation thinks.

Sales stops over-promising, because delivery now sees what was promised. Delivery stops absorbing scope creep, because there's a process for it. Finance stops chasing ghost information, because the information arrives on time.

The job stops being a relay race where the baton gets dropped between runners. It becomes a single conversation with three participants.

That's not a reporting improvement. That's an operational one. And it's where most of the quietly lost margin in project businesses lives.
