How it works for HVAC contractors

Does Paidnice work with ServiceTitan?
Many HVAC contractors run ServiceTitan for dispatch and QuickBooks Online for the books, and that pairing is exactly where Paidnice sits. ServiceTitan exports posted invoice batches into QuickBooks Online, Paidnice reads them there, and the reminders, statements, and late fees run from the ledger. Nothing changes inside ServiceTitan. The same pattern works for Jobber and simPRO into QuickBooks Online or Xero, and for AroFlo into Xero.
Can an HVAC contractor charge late fees on overdue invoices?
HVAC contractors can state late fee terms on every invoice and service agreement, and Paidnice applies the policy you set: it posts the fee or interest to the invoice in QuickBooks or Xero on your schedule, with every charge documented. State rules on rates vary, so check what applies where you work before you set the percentage.
How does Paidnice know which invoices to chase?
Every invoice your HVAC field software pushes into QuickBooks or Xero is in scope the moment it lands, whether it is a service call, a quarterly preventive maintenance visit, or a system replacement. You set the policy once: which customers get chased, on what schedule, and when fees apply. New invoices pick up the policy automatically, and anything already overdue today can be included from day one.
What does Paidnice cost for HVAC contractors?
HVAC contractors pay for Paidnice by invoice volume, not revenue. Essentials starts at US$69, £49 or A$99 a month, there are no contracts, and your first 20 actions are free.
What about a customer who disputes one invoice?
HVAC work attracts disputes: a warranty callback on a compressor, a property manager arguing a change order. Pull that one invoice out of the policy by its reference and the chasing pauses on it alone, while every other invoice the customer owes keeps moving. When the argument settles, put it back.
Does it work for maintenance agreement billing?
HVAC maintenance agreements bill small and often, and those are the invoices that slip when the office is buried in dispatch. Put agreement holders in their own group with a gentler cadence, keep firm terms and late fees on commercial trade accounts, and both run at once from the same QuickBooks or Xero. A multi-site customer gets one consolidated statement covering every location.
What about a system replacement billed in stages?
HVAC replacements usually bill a deposit and a balance on completion, and Paidnice chases each on its own due date. The deposit is chased until paid, the balance starts its schedule the day you raise it, and a reminder can name the late fee coming if it slips.

Collect the busy season's cash before it goes quiet.

Connect Xero or QuickBooks and Paidnice prepares draft policies for you. Nothing runs until you approve them.
