Taking commercial calls: POs, NTE limits and site contacts

Why commercial calls need their own intake

A homeowner who calls about a broken AC is the customer, the decision-maker, the site contact and the payer all at once. A commercial call usually splits those roles among several people. The caller may be a store manager, the approver a regional facilities manager, the site contact a shift lead and the payer an accounts payable team in another state.

Miss any one of them and the job goes wrong: the tech can't get in, the work stops waiting for approval, or the invoice bounces back for a missing PO number and sits unpaid for weeks. The fix is a commercial intake form that the CSR fills in completely before dispatch.

A large market with demanding customers

The commercial building stock is large. EIA estimated 5.9 million US commercial buildings in its 2018 survey^[2]. Facilities teams have plenty of vendors to choose from: there were 227,045 services-to-buildings-and-dwellings establishments alone in 2023^[3], before counting HVAC, electrical and roofing contractors.

Commercial customers stay with vendors who make their admin easy. Accurate paperwork, on-time arrival and invoices that match the work order matter as much as the repair.

The fields to capture

Purchase orders and work orders

Many commercial customers issue a PO or work order number for every job and reject invoices without it. Some send work orders through a facilities management platform; others email them. Ask on every call how the customer issues authorization, and record the number in the job before the tech is dispatched.

• If the caller doesn't have the number yet, record who will send it and by when, and flag the job.
• Never invent a placeholder number; it will be rejected later.
• If the customer uses a portal, note whether the tech must check in and out on the portal, which some contracts require for payment.
• Keep a customer profile with their standing rules, so CSRs don't have to ask the same questions each time.

Handling not-to-exceed limits

1. 01

   Record the limit at intake

   Write the NTE amount and the name of the person who set it on the job, visible to the tech.

2. 02

   Diagnose before committing

   The tech diagnoses and estimates the repair before starting any work that could exceed the limit.

3. 03

   Stop and call if it will go over

   If the repair will exceed the NTE, the tech or office calls the approver with the diagnosis, the options and the new amount.

4. 04

   Get the approval in writing

   Record who approved, the new limit and the time, and ask the approver to update the PO or confirm by email.

5. 05

   Invoice to the approved amount

   Invoice only what was approved, with the approval reference. Surprises on commercial invoices damage relationships fast.

Unapproved hours are expensive to write off. Private employers' total compensation costs averaged $46.89 per hour worked in June 2026, of which $14.07 was benefits^[1]. An hour your tech spends waiting for a decision, or working past an NTE that later gets disputed, carries that cost whether or not you can bill it.

Site contacts and access

Commercial sites have rules, and they vary by site. Capture them once and keep them on the customer profile.

• The site contact for this visit, with a mobile number, and a backup.
• Access hours. Most employed people work weekdays: 81% worked on an average weekday in 2025, against 30% on an average weekend day^[4]. Weekend or night visits often need a key holder arranged in advance.
• Where to check in, badge or escort requirements and any safety training the site requires.
• Parking, loading dock rules and roof access arrangements.
• Whether the work will disrupt the business, such as power shutdowns or noisy work, and when that is allowed.

Billing details that get you paid

• The billing contact and email, which is often accounts payable rather than the caller.
• How invoices must be submitted: email, portal or mail.
• What must appear on the invoice: PO number, site number, work order number, tech sign-off.
• Payment terms agreed in your contract.
• Whether photos or a service report must be attached.

Getting these right at intake is the cheapest way to shorten the time to payment.

A script for facility manager calls

• "Thanks for calling. Which site is this for, and is there a work order or PO number yet?"
• "Who is authorized to approve the work, and is there a not-to-exceed amount on this one?"
• "Who will meet our technician on site, and what are the access hours?"
• "Is there anything about the site we need to know, such as sign-in, roof access or work that can't happen during opening hours?"
• "Where should the invoice go, and does it need anything specific on it?"
• Close by confirming the response time your agreement promises, and say what happens next.

Response times and service agreements

Many commercial customers have contracts that set response times, such as a technician on site within a fixed number of hours for emergencies. Put those terms in the customer profile, and flag them on the job so dispatch can see them. If you can't meet a contract response time because the board is full, tell the approver straight away and agree a time, rather than letting the deadline pass. Our guide to what to say when the schedule is full has wording that works for commercial callers too, and our guide to the same-day service promise covers what you can honestly advertise.

Example: one rooftop unit, three contacts

Example: a fictional HVAC contractor takes a call from a store manager whose rooftop unit is blowing warm air. The CSR uses the commercial form: the store manager is the site contact, the approver is the regional facilities manager, and the work order arrives through the customer's portal with an NTE amount. On site, the tech finds a failed compressor, far beyond the NTE. He stops, the office calls the regional manager with the diagnosis and two options, and gets written approval for a replacement on a revised PO. The invoice goes to the portal with the work order number, photos and the approval reference, and is paid on the agreed terms.

Closing out the job

Commercial work is not finished when the tech leaves the roof. Facilities teams judge vendors on the close-out as much as the repair.

• The tech checks out with the site contact, explains what was done and gets a signature or portal sign-off if the contract requires it.
• The service report lists the equipment, the problem found, the work done, parts used and any recommendations, with photos.
• Recommendations that need approval, such as a failing motor on a second unit, go to the approver as a separate quote, not as a surprise line on the invoice.
• The office submits the invoice within the agreed time, with every reference the customer asked for.
• Anything left open, such as parts on order, gets a date and an owner, and the approver hears about it before they have to ask.
