Where parking revenue leaks at the gate.
Parking revenue leaks at the gate in a handful of predictable ways: tailgating, unpaid exits and drive-offs, lost-ticket and ticket-swapping abuse, permit sharing, validation abuse, and uncollected overstays. Each one is a vehicle that used a space without paying what it owed — and most of it is invisible: some leaks never appear as a transaction at all, and the rest hide inside transactions that look normal but are underpaid.
That's also why there's no honest industry "leakage average" to quote — leakage depends too much on your pricing, traffic, and enforcement for a single percentage to mean much. The number that matters is your own, and you can get a first-order read in about a week: count leaks (tailgating, drive-offs) show up as entries with no accounted-for exit; underpayment leaks (ticket-swaps, validation abuse, overstays) hide inside normal-looking paid exits and need a quick duration spot-check. Below is each mechanism, how to spot it in your own data, and how plate-based access closes it.
The criteria that actually matter here.
Tailgating at the gate
Two vehicles through on one arm-lift. Exit-side tailgating shows up as an entry with no matching exit; entry-side tailgating often leaves no record at all — a camera catches the second vehicle either way.
Unpaid exits & drive-offs
A driver who forces the arm, follows another car out, or leaves through a broken lane. The car leaves; the revenue doesn't.
Lost-ticket & ticket-swapping abuse
A long-stay driver swaps for a fresh ticket, or claims a lost ticket, to pay a flat minimum instead of the real duration.
Permit sharing
One monthly permit credential used by several vehicles, or kept after the holder has left — you're carrying cars you're not billing.
Validation abuse
Validations applied to vehicles that don't qualify, or reused — discounts leaking to non-customers.
Uncollected overstays
A vehicle that stays past its paid or permitted window and simply drives off, with no mechanism to bill the difference.
Every entry and exit is tied to a plate
The plate is the credential and the record, so entries reconcile against exits — and the tailgating and drive-off gap becomes visible and attributable instead of invisible.
No ticket to lose or swap
Entry is on the plate, so there's no paper ticket to lose, swap, or claim; the duration is simply the timestamped entry-to-exit on that plate.
Permits bound to a plate, revocable from the list
A permit is the plate, not a shared fob or code, so there's nothing separate to hand around — and it drops off the list the moment it should stop working.
A photo-verified record of every crossing
A plate photo, a full-vehicle image, and a short clip per crossing — the evidence to resolve a disputed exit or a challenged validation.
Overstays enforced on your rules
Once your payment processor is connected, an overstay can be billed automatically on exit, per your rules — turning the uncollected difference into a collected one.

Plate reading and the open/deny decision run on-site in under a second, and keep working — fully local for up to 30 days — if the internet drops. Most facilities qualify without replacing lane equipment.
An honest answer cuts both ways.
- If your site is fully attended with disciplined manual controls and low volume, the leak may already be small — measure first (entries vs accounted-for exits) before investing.
- This addresses vehicle-gate revenue; it doesn't fix non-gate losses like in-app payment fraud or cash-handling at a staffed booth beyond what the gate record can show.
- Pedestrian and non-vehicle access isn't the use case — this is about the vehicle lane.
The honest way to size your leak is from your own data, not an industry percentage nobody can verify. Start with the count leak: pull a typical week of gate records, count entries, then count every exit you can account for — paid, permitted, and validated — and adjust for the vehicles parked at the start and end of the window. The residual gap, times your average ticket value, is a first-order estimate of what's slipping through on tailgating and drive-offs. Then catch the underpayment leaks — lost-ticket, validation abuse, overstays — by sampling exits and comparing each stay's real entry-to-exit time against what was actually charged.
Where a staffed booth is the alternative for policing all this, that typically runs $10,000–$18,000 per gate each month depending on traffic and staffing; plate-based access makes the record automatic instead. Put your own numbers in the calculators below.

- Why is my parking garage losing revenue at the gate?
- Usually a mix of tailgating, unpaid exits and drive-offs, lost-ticket or ticket-swapping abuse, permit sharing, validation abuse, and uncollected overstays. Each is a vehicle that used a space without paying what it owed. Some never appear as a transaction at all; the rest hide inside normal-looking paid exits that were underpaid.
- How do I measure parking revenue leakage?
- From your own gate records, not an industry average. For tailgating and drive-offs, count a typical week's entries against every exit you can account for — paid, permitted, and validated — adjust for cars parked at the start and end of the window, and multiply the residual gap by your average ticket value. For underpayment leaks like ticket-swaps, validation abuse, and overstays — which look like normal paid exits — sample exits and compare each real entry-to-exit time against what was charged. Trend it monthly.
- Is there an industry average for parking revenue leakage?
- Not one we could verify. Published figures exist, but they vary wildly and rarely disclose how they were measured or on what mix of sites — leakage depends too much on your pricing, traffic, and enforcement for a single percentage to mean much. If someone quotes you one, ask how it was measured and on whose sites. The honest number is your own, and it takes about a week to get.
- How does license-plate access reduce revenue leakage?
- It ties every entry and exit to a plate, so entries reconcile against exits and the tailgating and drive-off gap becomes visible; there's no ticket to lose or swap; permits are bound to a plate and revocable from the list; and every crossing is photo-verified. Once your payment processor is connected, overstays can be billed automatically on exit, per your rules.
- Do I need to replace my gate or lane equipment?
- Usually not — it installs on the gate and lane most facilities already have, reads plates and makes the open/deny decision on-site in under a second, and keeps working (fully local for up to 30 days) if the internet drops. Send a few photos of your lane and we'll confirm yours qualifies.
