The invoicing feature that actually moves the needle for a plumbing business is a flat-rate price book with good-better-best presentation, not the invoice template itself. QuoteIQ Pro at $149.99 per month bundles a native flat-rate price book with tiered options presentation built for exactly this. Jobber at $49 per month covers on-site payment collection and a configurable price book at a lower entry cost for smaller shops. Whichever platform you choose, confirm the actual credit card processing rate rather than trusting a vague competitive fees claim, since that percentage compounds against every invoice you ever send.
Key takeaways
- QuoteIQ Pro at $149.99 per month includes a native flat-rate price book with good-better-best tiered options, built specifically for plumbing and HVAC presentation-style selling.
- Jobber's Core plan starts at $49 per month for one user and includes a configurable price book for flat-rate services.
- Credit card processing on Jobber and Housecall Pro is commonly reported at 2.9% plus $0.30 per transaction, matching the industry standard set by Square and Stripe, though neither vendor publishes this rate directly on its site.
- ACH bank transfer payments typically run under 1%, meaningfully cheaper than card processing on large repipe or remodel invoices where a customer can be steered toward paying by bank transfer.
- Deposit and progress billing support matters specifically for repipe and larger plumbing jobs, where collecting the full amount only at completion creates real cash flow risk.

We weighted flat-rate price book depth heavily, since a plumber presenting three price tiers on the spot closes more work than one quoting a single number and hoping. We also checked payment processing rates directly where vendors publish them, and note plainly where a platform only advertises competitive fees without a number attached.
QuoteIQ Pro: built specifically for flat-rate selling
QuoteIQ Pro at $149.99 per month includes a native flat-rate price book with good-better-best tiered options presentation, the exact selling method most successful plumbing shops use on a service call. Rather than quoting one number, the technician presents three options on a tablet, which consistently increases average ticket size compared to a single flat quote. The plan also includes scheduling, dispatching and maintenance agreement management alongside invoicing.
Best for: plumbing shops of one to five technicians wanting tiered pricing presentation without a separate price book tool.
- Purpose-built good-better-best presentation rather than a generic line-item invoice.
- Bundles scheduling and dispatch, avoiding a second subscription.
- Higher entry price than Jobber's base tier for a solo operator.
- Smaller installed base and review history than the established platforms.
Jobber: the lower-cost entry point
Jobber's Core plan at $49 per month for one user includes a configurable price book for flat-rate services, on-site invoicing, and payment collection through Jobber Payments. Credit card processing is commonly reported at 2.9% plus $0.30 per transaction, in line with the industry-standard rate charged by Square and Stripe, though Jobber's own site describes its fees only as competitive without publishing the exact percentage.
Best for: plumbing shops from solo up to about fifteen field users wanting the lowest credible entry price.

Housecall Pro: invoicing tied to membership billing
Housecall Pro ties recurring membership plan billing directly into its invoicing flow, useful for plumbing shops selling annual maintenance agreements alongside one-off service calls. Pricing runs $59 per month annual, $79 monthly, and it carries a 4.7 rating from more than 2,800 Capterra reviews.
Best for: plumbing shops combining one-time service invoicing with recurring membership billing.
ServiceTitan, ServiceM8 and Service Fusion
ServiceTitan's pricebook is the deepest good-better-best presentation tool in this category, reflecting its per-technician pricing that reportedly runs $245 to $500 or more per month, plus setup fees commonly in the $5,000 to $50,000 range. This only makes sense for plumbing operations large enough to have a dedicated team managing the pricebook itself.
ServiceM8's job-priced, unlimited-user model remains the cheapest credible option for a solo plumber, starting free and running $29 per month for 50 jobs, though its price book tooling is more basic than the dedicated flat-rate platforms.
Service Fusion partners with Profit Rhino for flat-rate price book support and charges $208 to $533 per month flat with unlimited users, worth comparing once a plumbing shop's headcount passes about twelve.
Payment processing rates worth confirming before you sign
Every platform in this category takes a cut of every card payment processed, and the rate compounds meaningfully across a year of invoices. The commonly reported industry-standard rate for Jobber and Housecall Pro is 2.9% plus $0.30 per card transaction, matching what Square and Stripe charge broadly, though neither vendor publishes this figure directly on its own pricing page, describing it only as competitive. ACH bank transfer payments typically run under 1%, meaningfully cheaper on large invoices, and steering a customer toward bank transfer on a $10,000 repipe job rather than a card can save real money on the processing fee alone. Confirm the exact current rate with any vendor before assuming a number, since processing rates are set by payment terms that can change independently of the software subscription price.
Parts markup: the invoicing detail that quietly kills margin
A surprising number of plumbing shops invoice materials at cost, or worse, forget to mark them up consistently across technicians. A price book with parts markup rules built in, rather than a technician typing in a number from memory, standardizes this across the whole crew and protects margin on every job automatically. QuoteIQ Pro and ServiceTitan handle this natively inside the pricebook, while Jobber and Housecall Pro require the markup to be configured per line item or product catalog entry. Whichever platform you pick, audit a sample of recent invoices for consistent markup before assuming the software is enforcing what you think it is.
Choose based on your selling method
- Choose QuoteIQ Pro if good-better-best tiered pricing presentation is central to how you sell.
- Choose Jobber if you want the lowest credible entry price with a configurable price book.
- Choose Housecall Pro if membership billing runs alongside your one-time invoicing.
- Choose ServiceM8 if you are solo and want the cheapest way to invoice without an idle seat cost.
- Choose Service Fusion if you have 12 or more users and per-seat pricing is inflating your bill.
Invoicing is only half the picture; see job costing for contractors to make sure invoiced amounts actually track back to real profitability, and QuickBooks job costing setup for the accounting side. For the trade-agnostic comparison, see invoicing software for contractors, and if bigger repipe jobs need a payment plan to close, Hearth financing for plumbers runs through the numbers.
How we put this together
Pricing was read directly from each vendor's own pricing page in August 2026 where published, including QuoteIQ, Jobber, Housecall Pro and Service Fusion. Payment processing rates for Jobber and Housecall Pro are commonly reported at 2.9% plus $0.30 per transaction, consistent across multiple independent industry sources, though neither vendor publishes this figure on its own site, and we flag that gap explicitly. ServiceTitan pricing figures are industry estimates, since ServiceTitan does not publish self-serve pricing. Confirm current numbers directly with any vendor before buying.
Frequently asked questions
What is the best plumbing invoicing software for flat-rate pricing?
QuoteIQ Pro is built specifically around good-better-best flat-rate price book presentation, which is the selling method most successful plumbing shops use rather than quoting a single number.
How much do plumbing invoicing platforms charge for credit card processing?
Jobber and Housecall Pro are commonly reported to charge 2.9% plus $0.30 per card transaction, matching the industry standard set by Square and Stripe, though neither publishes this rate directly and you should confirm the current figure before signing up.
Is ACH payment cheaper than credit card for a plumbing invoice?
Yes, ACH bank transfer payments typically run under 1%, meaningfully cheaper than the roughly 2.9% card processing rate, which matters most on large invoices like repipe or remodel jobs where the dollar difference is significant.
Do I need a dedicated flat-rate price book tool or will a generic invoicing app work?
A generic invoicing app works fine for straightforward time-and-materials billing, but a plumbing shop selling good-better-best tiered options on service calls will see a real difference from software built specifically around that presentation, like QuoteIQ Pro or ServiceTitan's pricebook.
How does deposit and progress billing work for plumbing repipe jobs?
Most platforms compared here support splitting an invoice into a deposit collected before work starts and progress payments tied to project milestones, which reduces cash flow risk on larger jobs compared to invoicing only once at completion.
What is the cheapest plumbing invoicing software?
ServiceM8's free plan and $29 Starter tier are the cheapest options with unlimited users, though price book and invoicing features are more basic than the dedicated flat-rate platforms like QuoteIQ Pro.
