01Labor Billing & Minimums
Labor is billed at the rates stated in the applicable estimate, work order, or other written agreement. Premium rates may apply to work performed after 4:30 PM on weekdays, on Saturdays and Sundays, or as otherwise identified in the estimate. A four-hour minimum applies per technician, per separate field-labor call unless otherwise stated. After the applicable minimum has been satisfied, labor is billed in 0.5-hour increments. Cornerstone may waive minor overages at its discretion.
02Separate Calls, Recall & Remobilization
A new field-labor call begins when a technician has been released and is later asked to return or perform additional client-requested service. Once released, any later client-requested remobilization is subject to a new four-hour minimum, whether the request involves exhibit work, moving or adjusting items, purchasing materials, delivery, or other project service.
03Planned Logistics & Errand Services
Planned logistics activities such as FedEx/UPS drop-offs, warehouse runs, freight handoffs, rental pickup or return, and similar errands are billed at the applicable labor rate with a one-hour minimum. The one-hour logistics minimum does not apply when a released technician must be recalled; in that case, the Recall & Remobilization policy applies.
04Onsite Supervision
Onsite supervision responsibility must be confirmed before an estimate is issued. If Cornerstone is responsible for crew direction, onsite coordination, interpretation of setup requirements, or field decision-making, an applicable supervision or coordination charge may apply as stated in the estimate or other written approval. If supervision responsibility changes after approval, the added supervision is treated as additional scope.
05Standby & Delays
Labor remains billable while Cornerstone personnel are onsite, available, and prepared to work but are unable to proceed because of client, venue, freight, exhibitor, other contractor, or third-party conditions. Personnel remain on the clock until released. If released and later recalled, the Recall & Remobilization policy applies.
06Additional or Changed Scope
Work requested beyond the approved estimate, or additional labor, materials, equipment, travel, or logistics required because of changed scope, incomplete information, inaccurate information, access conditions, freight issues, or other circumstances outside the original estimate, may be billed in addition to the approved amount. Cornerstone will communicate material added cost before proceeding when practical. When immediate action is reasonably required to keep the project moving, Cornerstone may proceed and bill the additional work at the applicable rates and terms.
07Cancellation & Rescheduling
More than 48 hours before the scheduled call: no labor cancellation fee, but non-refundable project costs already incurred remain billable. Between 24 and 48 hours: 50% of the applicable scheduled labor minimum per technician, plus non-refundable costs. Less than 24 hours, same-day cancellation, or crew already dispatched: the full applicable scheduled labor minimum per technician, plus travel and other project costs already incurred. Rescheduling inside these windows may be treated the same way when labor or costs have already been committed.
08Materials, Hardware & Specialty Items
Job-specific materials, hardware, consumables, specialty bits, blades, adapters, and similar items purchased specifically for a project are billed at actual cost, plus any applicable procurement, handling, sourcing, or coordination charge stated in the estimate or other written approval. Because these items are billed to the client, the client may retain them at project completion. Items the client does not wish to retain may be left with Cornerstone for future use or disposal.
09Rental Equipment
Rental equipment arranged by Cornerstone is billed at actual rental cost, plus any applicable rental coordination, handling, or procurement charge stated in the estimate or other written approval. Pickup and return labor is billed separately under the applicable logistics or remobilization rule. Client-, exhibitor-, venue-, or project-caused rental damage, loss, late fees, cleaning fees, replacement charges, or similar vendor costs are billed to the client at actual cost. Charges caused by Cornerstone are not passed through to the client.
10Parking, Tolls & Venue Charges
Parking, tolls, union or venue-imposed charges, and similar direct project expenses are billed at actual cost when applicable.
11Shipping & Freight Handling
Third-party carrier, postage, and freight charges paid by Cornerstone are billed at actual cost. Cornerstone labor required for freight paperwork, packing, repacking, palletizing, carrier handoff, warehouse runs, delivery, pickup, or other shipping-related services is billed at the applicable labor rate and minimum. Job-specific shipping materials are billed at actual cost plus any applicable procurement or handling charge stated in the estimate or other written approval.
12Local & Regional Travel
A venue located 40 miles or less one way from the assigned technician's local base is treated as local and carries no travel labor or mileage charge unless otherwise stated. A venue located more than 40 miles one way is treated as a travel job. For a travel job, all actual round-trip travel time is billable for each traveling technician at the applicable labor rate, and the entire round-trip vehicle mileage is billed at the mileage rate stated in the applicable estimate or written agreement. The 40-mile threshold determines whether travel billing applies; it is not a free-mile allowance once the job qualifies as travel.
13Overnight Travel, Lodging & Meals
When overnight travel is reasonably required, Cornerstone will arrange commercially reasonable lodging suitable for business travel and bill lodging at actual cost. Airfare, baggage, rental vehicles, airport parking, tolls, and other required travel expenses are billed at actual cost. Meal per diem or other travel allowances, when applicable, are billed at the amounts stated in the estimate or approved travel terms.
14Air Travel Time
Required air-travel time is billable from the time the technician begins travel to the originating airport until arrival at the destination hotel, venue, or other required project location. For domestic flights, Cornerstone uses a standard 1.5-hour pre-departure airport allowance. Billable travel includes reasonable travel to the airport, the pre-flight window, check-in/security, boarding, flight time, normal connections and layovers, baggage claim, rental-car or ground-transport pickup, and travel to the destination. Return travel is billed on the same basis. Unnecessary personal extra time or detours are not billable.
15Rush / Short-Notice Work
Short-notice work is accepted subject to crew and equipment availability. Additional costs required to fulfill a short-notice request—including premium labor, expedited rentals, special delivery, travel, procurement, or other rush-related costs—are billable. Any separate rush or special-handling charge will be identified in the applicable estimate or written approval.
16Estimate Validity & Availability
Estimates are valid for 30 days unless otherwise stated. After 30 days, Cornerstone may re-confirm pricing, labor availability, equipment availability, travel, and schedule before accepting the work. Approval of an estimate does not guarantee crew or equipment availability until Cornerstone confirms the job on the schedule.
17Payment Terms
Established business clients are generally invoiced on Net 30 terms unless otherwise stated. Cornerstone may require a deposit or prepayment from new or higher-risk clients before committing labor, rentals, equipment, or travel. Past-due balances may result in future work being held or not scheduled. Any late charge will apply only when clearly stated on the applicable estimate, invoice, or agreed terms.
18Courtesy Waivers & Adjustments
Cornerstone may waive or reduce a charge at its discretion. Any waiver or reduction is a project-specific courtesy and does not modify Cornerstone's applicable rates, minimums, or terms for future work.
19Taxes
Applicable sales, use, or similar taxes will be added when required by law. Tax treatment may vary by project location, service type, materials, rentals, and client exemption status.
20Acceptance
Approval of a Cornerstone estimate by email, purchase order, signed estimate, or other written authorization constitutes acceptance of the Standard Service Terms version identified on that estimate unless alternate terms are agreed to in writing by Cornerstone Exhibit Services LLC.
