HVAC tickets swing from a $150 service call to a $15,000 system replacement, and that range changes how you get paid. Small jobs should be invoiced and paid on the spot, before the tech leaves. Big replacements often depend on financing. A homeowner who balks at a five-figure price will often say yes to a monthly payment they can see before you leave the kitchen table.
When you compare invoicing and payments tools, look at whether techs can invoice and take a card or bank payment from the field app, how processing fees compare (they add up fast on large tickets), whether financing offers can be shown inside the quote, and how payments sync to your accounting software. Follow-up matters too: automatic reminders for unpaid invoices recover more money than an office manager with a list.
The list starts with tools for contractors. Hearth combines estimating, invoicing, and customer financing for home improvement contractors, and Wisetack offers pay-over-time financing for service businesses. ServiceTitan, FieldEdge, WEX Field Service Management, Housecall Pro, and Jobber build invoicing and payments into field service software. Joist and Invoice2go are mobile estimate-and-invoice apps. QuickBooks, Square, and Stripe cover accounting and payment processing behind the scenes.
Pricing snapshot from our listings (last checked 2026-11-11): One of these 12 tools puts a starting price on its own site: Jobber ($29/month). Joist, QuickBooks, and Square list a free plan or free tier. One asks you to contact sales for a price (Hearth). The others publish plans on their own pricing pages, which we link from each tool's page rather than repeat here. Prices change often, so confirm on the vendor's page before you buy.
