Where invoicing slips in plumbing and HVAC shops
In a busy season, finished jobs pile up as open work orders. The tech forgot to add the second trip, the parts list is missing a fitting, or the photos are there but the notes just say "fixed." Each one takes ten minutes of detective work, so it waits, and the longer an invoice waits the less likely it is to be paid on time. An invoicing and collections team clears that pile daily and follows a fixed process once the invoice is out.
What invoicing and collections support includes
- Reviewing completed jobs for missing labor, parts, trip charges and photos before invoicing.
- Applying your pricebook or flat-rate items consistently, and flagging anything that looks off for your approval rather than guessing.
- Sending invoices and payment links through your software, and resending when a customer says one never arrived.
- Working the accounts-receivable aging report on a schedule, with reminder emails and texts you approved in advance.
- Logging disputes and complaints in the customer's own words and passing them to you. The team doesn't negotiate or write off balances.
- Matching payments in your accounting software and keeping customer balances in sync between systems.
- Collecting lien-waiver and progress-billing paperwork for builder and property-manager accounts, if you do that work.
A past-due reminder sequence to start from
| When | What goes out | Tone |
|---|---|---|
| Job day | Invoice and payment link | Thanks for the work, here's your invoice |
| Due date | Friendly reminder with link | Just a reminder |
| A week or two past due | Second reminder, offer to answer questions | Checking in, anything wrong with the work? |
| 30+ days | Account review, owner decides next step | Handed to you |
Adjust it to your terms. Commercial and property-management accounts often have net terms and their own vendor portals, so they need a separate track from homeowners who pay on the spot.
Rules on collection practices, late fees, sales tax on service and materials, and mechanic's lien notices differ by state and change over time. Your accountant or attorney should set those rules, and the back-office team follows them.
Software access and handling money
Give the support team permission to create and send invoices and record payments. Think hard before granting rights to issue refunds, change bank details, delete transactions or see full card numbers. Card payments should run through your payment processor's hosted links so nobody on the team ever touches card data. Ask any provider how they remove access when a staff member leaves, and whether they can work with two-factor sign-in on your accounts.
Accounts-receivable reports worth asking for
- Jobs completed but not invoiced, with age.
- Aging buckets: current, 1-30, 31-60, 61-90, over 90 days.
- Open disputes and who owns each one.
- Invoices changed after the tech submitted them, and why.
Unpaid estimates are a separate list. Estimate follow-up covers quotes the customer hasn't accepted yet, and dispatch support keeps job records complete enough to invoice from.
Invoicing and collections FAQ
Can you invoice from techs' paper tickets?
Yes, if the tickets are photographed or scanned the same day. It's slower and more error-prone than tickets completed in an app, so most shops treat it as a stopgap.
Will you send accounts to a collection agency?
A back-office team shouldn't make that decision. They prepare the account history and you decide.
