How Tollgate treats ROI

There’s a common misreading worth clearing up: that Tollgate is squeamish about ROI. It isn’t.

Tollgate computes the ROI-family metrics explicitly — NPV, IRR and payback — in the financial case. Those numbers are the target you commit to. What it deliberately does not do is keep a live “realised ROI” score that updates itself through delivery as the governance signal. The forward number is a benchmark to steer against. It is not a scoreboard the tool keeps ticking.

Two different moments, two different treatments. At commitment, ROI is arithmetic. At realisation, it’s judgement.

At commitment, the target is computed

When the business case is submitted for Approval, it carries a financial case — a period-by-period net cashflow from which Tollgate computes:

NPV — net present value by discounted cash flow, at a discount rate you set (default 8%).
IRR — the rate at which NPV is zero, solved numerically.

Where the cashflows never turn positive, or turn more than once, Tollgate says so rather than showing a misleading figure.
Payback — the period at which the upfront outlay is recovered, with a discounted-payback variant alongside it.

These are real calculations, and you produce them one of two ways. Build the model inside Tollgate, or attach the figures your finance team already ran and record them against the case. Either way the number does what a forward number should. It forces the assumptions into the open and gives the investment a defensible bar for later.

Through delivery, your outcome status and confidence are tested against that target, alongside the rest of the case: the outcome statement, the KPIs, adoption. It’s a reference line you steer by, not a live tally the tool recomputes for you.

See Build or attach a financial case for how the NPV/IRR/payback figures are produced.

At realisation, the verdict is judged, not recomputed

What Tollgate will not emit is a single realised ROI. That is a variance of actual against expected, recomputed as delivery proceeds and shown with a green tick. On a real technology investment that number is false precision, for three reasons:

Counterfactuals are invisible.

The true return needs the world where you did not invest, and that world never ran. There’s nothing to measure against.
Attribution windows are long.

The benefits of a platform migration or a transformation arrive over years. They tangle with everything else the organisation did in the meantime.
Causal chains are contested.

Did the uplift come from this investment, the market, a reorganisation or three other programmes? That is argument, not arithmetic.

A tool that emits one realised number where all that subtlety lives isn’t a precision instrument. It’s a polite fiction with a green tick. And a green tick is exactly what a steering committee trusts without interrogating. The forward target is a stated assumption you can argue with. A live realised score pretends the argument is settled. That’s governance theatre: the appearance of measurement stands in for the judgement no one actually made.

At the verdict, then, Tollgate’s signal against the target is a human decision, not a recomputed measurement.

What Tollgate holds instead — the target and the prose pair

The case file carries both the computed figures and the words. Two prose artefacts sit beside the financial case:

Return expected — authored at Approval, in the sponsor’s own words: what this is for, beyond the number.

Immutable thereafter.
Return realised — authored at the Realisation verdict, in prose, by the person who signed the cheque.

At realisation the NPV/IRR/payback target is the benchmark. The verdict is the prose pair — what we said beside what we got — not a variance percentage. When the next sponsor searches for prior investments of a similar shape, those two paragraphs tell them far more than “ROI: 112%” ever could. They sit next to the original financial case.

The declaration is the governance act

At the verdict the sponsor declares Realised, NotRealised, or not ready yet. That declaration is the governance act: a named, accountable person puts their judgement on the record, against the target they were given. Tollgate’s job is to put what we said next to what we got, then keep that judgement quick to make and impossible to lose. It doesn’t dress an estimate up as a measurement to make the judgement for the sponsor.

This is the same instinct as the rest of the method. Above the line, Tollgate surfaces the case file — the numbers and the words — and lets the accountable person decide.

Failures are preserved more carefully than successes

Because the verdict is prose rather than a score, a NotRealised investment carries an elevated lessons field. Its record sits in the corporate memory more visibly than the successes, not less. The next sponsor about to fund a similar business case needs the honest account of the one that didn’t land. A single realised-ROI cell flattens that into a red square no one wants to click. The prose keeps the lesson findable. (This is “kill with dignity” in action.)

What this means when you’re using Tollgate

Build or attach the financial case — Tollgate computes the NPV/IRR/payback target from it.

That target is real, and it’s the benchmark.
Write return expected in plain language too — the sentence and the numbers are both part of the case.
Don’t look for a live realised-ROI variance dashboard — there isn’t one, on purpose.

Outcome status is judged against the target, not recomputed from it.
At the verdict, write what actually happened, honestly. The value of the record is the honesty, not a percentage.
