Residential jobs paid at time of service
The simplest lever for cash flow in residential work.
HVAC companies · Invoicing and collections follow-up
Get paid before the truck leaves, and stop chasing commercial invoices in month three
Residential HVAC should be simple: the technician finishes, presents the invoice on a tablet and the homeowner pays. In practice, some jobs are invoiced later, financing paperwork lags, and warranty parts claims sit open. Commercial and new construction work is harder, with property managers, general contractors and net-30 terms that quietly become net-90.
How it often works today
- Some residential jobs are invoiced after the visit because the technician could not finalize pricing on site, and those invoices are paid slowly.
- Commercial invoices go to a property manager's general inbox without the PO number or work order they need, so they sit unapproved.
- Builder and general contractor payments for new construction lag behind progress, and lien deadlines are tracked loosely if at all.
- Manufacturer warranty parts claims and financing company payments are reconciled by hand, so some money is never collected.
A collections workflow makes payment at the time of service the default for residential calls, tracks financing funding, and follows up commercial and builder invoices on a fixed schedule with the right contact and paperwork. The office manager decides on payment plans, holds and when the owner should call. The goal is fewer days between finished work and cash.
The improved workflow
Collect at the time of service
Technicians present invoices on the tablet before leaving, with card, ACH and financing options, and jobs closed unpaid are flagged to the office the same day.
Send commercial invoices with the right details
Invoices to property managers include PO numbers, work order references, photos and technician notes, sent to the approver named on the account.
Follow up on a fixed schedule
Reminders go out at set intervals after the due date. At a defined point, the office manager gets a task to call or escalate to the owner.
Track construction draws and lien dates
New construction jobs have draw schedules and lien notice dates tracked, with reminders to the office manager well before any deadline.
Reconcile warranty and financing
Open manufacturer warranty claims and financing company fundings are listed weekly, so the office can chase items still outstanding before they are forgotten.
How we deliver this: AI automation for small business or fractional CTO leadership, scoped in writing and run over 90 days. See pricing or the sample scope.
What we would measure
Days sales outstanding for commercial accounts
Shows whether better invoices and follow-up shorten collection time.
Receivables over 60 days
The balance most at risk of becoming bad debt.
Open warranty claims over 30 days
Uncollected warranty credits are pure margin loss.
Where people stay in control
- The office manager or owner approves payment plans, credit holds and any decision to stop service to a commercial account.
- Card and bank details are handled only through PCI-compliant payment processing, never typed into notes or sent by text.
- Mechanic's lien notices and deadlines are reviewed by the owner and the company's attorney; automation only provides reminders.
Example
Illustrative: a property management account
For example, a contractor services 40 rental units for a Denver property manager. Invoices used to go to a general inbox without work order numbers and often waited 70 days. Now each invoice includes the unit, work order, photos and technician notes and goes to the named approver. Reminders follow at set intervals, and the office manager calls at 45 days. This is illustrative, not a measured outcome.
Tools typically involved
What the first 30 days look like
In the first 30 days we would review a year of receivables by customer type, measure payment-at-service rate and commercial DSO, list open warranty and financing items and agree a follow-up schedule with your office manager.
Common questions
How do we get technicians to collect on site?
Make it easy and expected: pricing from the price book on the tablet, card and financing options ready, and a clear rule that jobs are not closed unpaid without a reason. Reporting payment-at-service rate by technician helps managers coach.
Can AI chase commercial customers for us?
It can draft reminders and pull the right documents together, but for commercial accounts the relationship matters. We would automate the routine reminders and paperwork, and leave calls and difficult conversations to the office manager or owner.
What about mechanic's liens in Colorado?
Colorado has specific notice and filing deadlines for mechanic's liens. The workflow can track dates and remind you, but the legal steps should be handled with your attorney. We would not give legal advice on lien rights.

Worth a closer lookTest the assumptions
Illustration only, not a forecast or guarantee. Recovered staff time becomes a cash saving only if spending actually declines or the time goes into paid work. Tool costs are an assumption; we replace every number here with yours before recommending a scope.
