Application fee (platform fee): An application fee is the amount a software platform takes from a payment processed on a connected account, most often through Stripe Connect. The payment processor also deducts its own processing fee, and the rest settles to the business. In Lotably, the application fee is Lotably’s only charge on a citation or parking payment.
Audit log: An audit log is a permanent, time-stamped record of who did what in a system, such as issuing, voiding, or reducing a citation, changing a fine, or refunding a payment. Ordinary users cannot edit or delete entries. In parking enforcement, the audit log backs up decisions on appeals and disputes and helps owners spot unusual voids or refunds.
Boot (wheel clamp): A boot is a device locked onto a vehicle’s wheel so it cannot be driven until the owner pays to have it removed. Booting on private property is regulated by state or local law in many places and banned in some, with rules on signage, fee caps, response times, and licensing. Operators should confirm booting is allowed where they work before offering it.
Chalking (tire chalking): Tire chalking is the practice of marking a parked car’s tire with chalk so an officer can prove later that it stayed past a time limit. In Taylor v. City of Saginaw (2019), the U.S. Court of Appeals for the Sixth Circuit held that chalking is a search under the Fourth Amendment, and in a 2021 ruling in the same case it held that the administrative-search exception does not justify suspicionless chalking. Those rulings bind federal courts in Kentucky, Michigan, Ohio, and Tennessee and apply to government enforcement, since the Fourth Amendment limits government officers. Recording the plate, location, and time digitally captures the same facts without touching the vehicle.
Citation (parking ticket): A citation, or parking ticket, is a notice that a vehicle broke a parking rule, stating the violation, the amount owed, and how to pay or contest it. A city citation is a government fine, while a citation on private property is usually a private charge whose enforceability depends on state or provincial law. Electronic citations typically carry photo evidence, a timestamp, and the amount owed as of the moment of issue.
Collection agency referral: A collection agency referral is the step where an unpaid parking citation or charge is handed to a third-party debt collector after notices go unanswered. In the US, collectors working consumer debts may be subject to the federal Fair Debt Collection Practices Act and to state rules, and whether a private parking charge can be collected at all depends on state law. Referral usually comes after the final notice, and collectors typically keep a percentage of what they recover.
Contest / appeal: A contest, or appeal, is the process a driver uses to dispute a citation. The driver gives a reason and any evidence, and the operator or a hearing officer reviews it and records a decision to uphold, reduce, or dismiss the citation. Some laws require private operators to offer an appeal method, and a clear, documented process tends to reduce complaints and payment disputes.
Direct charge: A direct charge is a Stripe Connect payment created on the connected account itself, so the payment belongs to that business, which also handles its refunds and disputes. The platform can collect an application fee on each direct charge. Lotably uses direct charges for citation and parking payments, so the money settles to the operator’s own Stripe account and Lotably never holds it.
Do-not-tow list (safelist): A do-not-tow list is a set of license plates that enforcement staff must not cite, boot, or tow at a property, such as vehicles belonging to staff, vendors, management, or a resident with a temporary arrangement. It sits alongside the permit roster and guest passes as one of the checks before any enforcement action. A well-kept list records who added each plate, why, and when the exemption ends.
Enforcement company: A parking enforcement company is a business a property owner hires to patrol a lot and enforce its rules, by issuing private citations or by booting or arranging tows where those are legal. It works under a written authorization from the owner and is paid a flat fee, a share of revenue, or some or all of what it collects. Many states license or regulate companies that boot or tow, while rules for companies that only issue private citations vary widely.
Escalation schedule (citation escalation): An escalation schedule is a set of disclosed, time-based increases to a citation’s amount, so an unpaid citation grows after defined windows such as 15 and 30 days. Recording the schedule on each citation when it is issued keeps the amount owed at any later date computable, even if the operator changes its fines afterward. State and local rules can limit how much and how fast a private charge may grow.
Event rate: An event rate is a flat price for parking during a concert, game, or other event, usually paid on arrival and valid until the event ends or a set time. It replaces the lot’s normal hourly pricing for that window. Operators near stadiums and venues set event rates per event because demand and length of stay are predictable.
Flat fee patrol: Flat fee patrol is a pricing arrangement in which a property owner pays an enforcement company a fixed amount per month or per visit to patrol a lot, regardless of how many citations are issued. The owner gets a predictable cost, and the patrol company has no financial reason to over-ticket. Citation revenue may go to the owner, the company, or be split, depending on the contract.
Gate arm: A gate arm is the barrier at a parking facility entrance or exit that lifts to let a vehicle through after a ticket is pulled, a credential is read, or a payment is made. It is the most visible part of a PARCS installation. Gated lots control access up front, while gateless lots let anyone park and rely on enforcement afterward.
Grace period: A grace period is a short window after a vehicle arrives, or after a paid session or time limit ends, during which it will not be cited. It covers the time drivers need to read signs, pay, or walk back to the car, and it cuts down on disputes over a minute or two. Some state laws set a minimum grace period for private lots, so check the rules where the lot is.
Guest pass (resident guest pass): A resident guest pass is temporary parking permission a resident issues for a visitor’s vehicle, usually for a set number of hours or days. Properties commonly limit guest passes with a quota per unit, such as a number of nights per month, so a long-term extra car cannot park as a permanent guest. Digital guest passes are registered by plate, so enforcement sees them in the same check as permits and paid sessions.
Late fee: A late fee is an added charge on a parking citation or invoice that is not paid by its due date. It is usually a fixed amount or a step increase disclosed on the citation and on posted signs. Some states and cities cap late fees on private parking charges or set how long a driver must have before one applies.
LPR / ALPR (license plate recognition): License plate recognition (LPR) is software that reads a vehicle’s plate from a camera image and turns it into text. ALPR (automated license plate recognition) and ANPR (automatic number plate recognition, the usual term in the UK) mean the same technology, though “ALPR” is often used for fixed or vehicle-mounted cameras that read every passing plate, while “LPR” also covers an officer scanning plates one at a time with a phone. In parking, the plate becomes the key for checking permits, paid sessions, and prior citations.
Lot: A lot is a physical parking location, such as a surface lot or a garage, within an operator workspace. A workspace can contain many lots, and they share the workspace’s brand, fine schedule, timezone, and payout account. Some per-lot details, like a pay-to-park QR code and price, can still differ.
Lot group: A lot group is a set of lots that share enforcement rules, so a permit or paid session valid in one is honored in the others. Operators use lot groups for a campus, a cluster of neighboring lots, or a garage and its overflow lot.
Monthly parker / permit: A monthly parker is a driver or company with an ongoing right to park in a lot, usually billed every month, and the permit is the record of that right. A permit names the vehicles and the lots or zones it covers. An active permit shows those vehicles as paid in those lots on the days and hours it allows.
Multi-tenant: Multi-tenant describes software in which many independent customers, called tenants, run on one shared platform with each tenant’s data, branding, users, and money kept separate. The vendor maintains one system and ships updates to every tenant at once. For parking operators, it means one company’s citations, parkers, and payments are never visible to another company.
Near-match (LPR misread protection): Near-match protection is logic that flags a scanned plate differing from a permitted or paid plate by a commonly confused character (O and 0, I and 1, B and 8) or a single swapped pair, before a citation is issued. Plate-reading software and people both make these errors, and without a check a misread becomes a wrongful ticket against someone who paid. The officer confirms or overrides the match, and the decision is logged.
Non-consensual tow: A non-consensual tow is a tow the vehicle owner did not request, such as removing an unauthorized car from a private lot at the property owner’s direction or an impound ordered by police. Because the owner has no chance to compare prices, many states and cities regulate these tows separately from owner-requested tows, with fee caps, sign rules, licensing, and notice requirements. Texas, for example, regulates private property tows under Occupations Code Chapter 2308.
Officer app: An officer app is the mobile application enforcement staff use in the field to scan or enter plates, check permits and paid sessions, take photos, and issue citations. Many run on ordinary smartphones, while older systems use dedicated handheld devices. Lots with weak cell signal make offline support and quick syncing as important as any feature.
Paid session: A paid session is a time-bounded right to park bought for a specific vehicle and lot, for example through pay-to-park or a pay station. It has a start time and an end time. While it is active, enforcement treats the vehicle as authorized and does not cite it.
PARCS: PARCS stands for parking access and revenue control system, the gates, ticket dispensers, credential readers, pay stations, and software that control who enters and leaves a facility and collect payment. It is typical in garages and large lots with defined entrances. Because PARCS needs hardware installation and upkeep, smaller and open surface lots often use gateless pay-to-park with enforcement instead.
Parking charge notice (private parking charge): A parking charge notice is a demand for payment issued by a private landowner or its agent, rather than a government, for breaking the posted terms of parking on private land. Its legal basis is usually contract or trespass law, not a traffic statute, so it carries no criminal penalty or license points. The term is common in the UK, where it is distinct from a council-issued penalty charge notice; in the US and Canada the same thing is usually called a private parking ticket or violation notice, and whether it can be enforced depends on state or provincial law.
Parking invoice: A parking invoice is a bill a private operator sends to a driver or registered owner for parking or for breaking a lot’s posted terms, framed as an amount owed rather than as a fine. Operators use the word to make clear the notice is a private charge, not a government ticket. Some state laws use the term and regulate what an invoice must say and when it is sent; Florida’s private parking statute, section 715.075, is one example.
Pay-by-plate: Pay-by-plate is a paid parking model in which the driver enters their license plate when paying, and the plate becomes the identifier for the parking session. There is no dashboard receipt or hangtag to display. Enforcement scans or types the plate and checks it against active paid sessions for that lot.
Pay-by-space: Pay-by-space is a paid parking model in which each stall has a number and the driver pays for that space rather than for a vehicle. Enforcement checks which space numbers are paid instead of reading plates or looking for a dashboard receipt. Pay-by-plate avoids its most common problem, a driver entering the wrong stall number.
Pay station: A pay station is a kiosk in a parking lot or on a street where drivers pay for parking by card, coins, or sometimes bills. Networked pay stations usually run pay-by-plate or pay-by-space and send each paid session to the enforcement system as it happens, while older ones print a receipt for the dashboard. One kiosk can serve a whole block or lot, which is why pay stations often replace single-space meters.
Pay-to-park: Pay-to-park is short-term paid parking that a driver buys on the spot, by app, web page, text message, or pay station, for a specific vehicle and lot. Common rate types are hourly, flat daily, and event pricing. In lots that also enforce, the paid session is checked when an officer scans the plate, so a driver who paid is not cited.
Photo evidence: Photo evidence is the set of time-stamped pictures an officer takes when issuing a citation, typically the plate, the vehicle in its position, and the sign or condition that shows the violation. Photos attached to the citation let the driver see what happened and let a reviewer decide an appeal on the facts. Location data and an unaltered original timestamp make the photos harder to dispute.
Property owner authorization: A property owner authorization is the written agreement in which a property owner or its agent permits an enforcement company or tow company to enforce parking rules on the property. It typically names the property, the rules and remedies allowed (citations, booting, towing), who may request a tow, and how revenue is handled. Some state towing laws require a current written authorization before a non-consensual tow from private property.
QR poster: A QR poster is a sign in a parking lot with a QR code that drivers scan with a phone camera to pay for parking, register a guest, or read the lot’s rules, with no app to download. Each poster is usually tied to one lot so the payment is recorded in the right place. Fake QR stickers placed over real ones are a known parking scam, so operators should inspect posters regularly and keep the payment page on a domain drivers can recognize.
Registration hold: A registration hold is a block a state motor vehicle agency places on renewing or transferring a vehicle’s registration until unpaid government parking tickets are paid. Some states let cities and parking authorities report unpaid citations this way, which makes it one of the strongest collection tools public agencies have. Private lot operators generally cannot use it, because the hold applies to government-issued tickets.
Relocator (Illinois): In Illinois, a commercial vehicle relocator, or relocator, is a business that removes trespassing vehicles from private property by towing or otherwise and then relocates and stores them. Relocators are licensed and regulated by the Illinois Commerce Commission under Chapter 18a of the Illinois Vehicle Code, which also provides permits for their operators and dispatchers. The term is specific to Illinois law; most other places call this private property or non-consensual towing.
Revenue share: A revenue share is an arrangement in which an enforcement company or parking operator keeps a percentage of the money a lot collects, from citations or parking payments, instead of or in addition to a fixed fee. It often means the property owner pays nothing upfront. The trade-off is that the company earns more when it writes more tickets, so the contract should set clear rules for what gets enforced.
Roster: A roster is the list of permit holders and their vehicles authorized to park at a property. Enforcement checks each scanned plate against it before issuing a citation. Keeping it current when residents or tenants change cars is the simplest way to prevent wrongful tickets.
Stripe Connect: Stripe Connect is Stripe’s product for platforms that route payments to many businesses, called connected accounts. A parking software platform can use it so citation and parking payments settle to each operator’s own Stripe account rather than the platform’s balance. Connect supports several charge types, including direct charges, destination charges, and separate charges and transfers.
Tenant / operator workspace: A tenant, or operator workspace, is the unit that owns a parking operation on a multi-tenant platform: one brand, one fine schedule, one timezone, and one payout account. A tenant can run as many lots as it needs under that brand. An operator with several distinct brands runs one tenant per brand from the same platform.
Thermal printer: A thermal printer is a small, battery-powered printer that prints on heat-sensitive paper, so it needs no ink or toner. Enforcement officers carry one, usually paired to a phone or handheld by Bluetooth, to print a citation for the windshield. Some operators skip printing and leave a pre-printed notice with a QR code that links to the full citation online.
Tow-away zone: A tow-away zone is an area, marked by posted signs, where unauthorized or illegally parked vehicles may be towed at the owner’s expense. On private property, most states require specific sign content before a tow is lawful, often the tow company’s name and phone number, where the vehicle will be stored, and the fees, and the details differ by state and city. On public streets, tow-away zones are set by local ordinance, commonly for fire lanes, rush-hour lanes, and street cleaning.
Transient parker: A transient parker is a driver who parks for a short, one-time visit and pays per use, as opposed to a monthly parker with an ongoing permit. Operators track transient and monthly revenue separately because they behave differently: transient demand follows time of day, events, and season, while monthly revenue is steadier. Transient parkers usually pay at a pay station, through an app or QR code, or to an attendant.
Validation (parking validation): Parking validation is when a business pays for or discounts a customer’s parking, usually as a perk for shopping, dining, an appointment, or a hotel stay. The business once stamped a garage ticket; digital validation applies a code, a QR scan, or an entry tied to the plate so the session is free or reduced. Under its agreement with the operator, the business is often billed for the validations it issues.
Virtual permit: A virtual permit is a parking permit tied to a license plate in a database instead of a physical hangtag or sticker. Enforcement confirms it by scanning or entering the plate. Virtual permits cannot be lost, copied, or handed to another car, and they can be issued, changed, or revoked online without mailing anything.
White-label: White-label software is built by one company and presented under another company’s brand, so drivers and staff see the operator’s name, logo, and colors instead of the vendor’s. In parking, a white-label platform lets an operator offer citation payment, permits, and pay-to-park under its own brand. The depth varies: some products support a custom domain and branded emails, others only a logo.
