Wisetack

Best for: HVAC, plumbing, and electrical shops doing $1,500-plus average tickets who want to close more jobs without turning down customers who can't pay upfront.
Our Take
Wisetack is a consumer financing platform built specifically for service businesses. Contractors send a text or invoice link, the customer picks a payment plan, and the job gets booked. The whole flow takes a few minutes. It's not field service management software. It's not scheduling or dispatch. It does one thing: let customers pay over time so contractors close bigger jobs without playing banker.
The pitch resonates with HVAC and plumbing shops most, where a $4,000 system replacement or $1,800 water heater install can sit on the table because the customer doesn't have cash. Wisetack steps into that gap. Rates run from 0% to 35.9% APR depending on creditworthiness, and the 0% APR option extends up to 24 months, which is competitive with what GreenSky and Service Finance Company offer. The merchant cost structure isn't published on the site, which is a real frustration when you're trying to compare options.
The contractor testimonials skew toward plumbing and electrical, and the platform has genuine traction, tens of thousands of businesses and a Deloitte Fast 500 ranking. It's also embedded in a growing number of field service management tools, so the integration question is increasingly moot for shops already running software like Jobber or Housecall Pro. The weak spot is transparency: pricing, exact partner software names, and approval rate data are all kept behind a sales call.
Pros
- Fast checkout flow means customers can approve financing and confirm a booking in the same conversation, reducing same-day cancellations.
- 0% APR option up to 24 months is competitive with specialty home improvement lenders like GreenSky.
- Embedded API integrations with field service management platforms reduce double-entry and keep the financing offer inside existing workflows.
- 85% of customers rate it 9 or 10 out of 10, which is unusually high NPS for a financing product customers often resent.
- Backed by U.S. Bank and Group 1001 capital partnerships, giving it more lending stability than smaller fintech competitors.
Cons
- Merchant fee structure is not disclosed publicly, requiring a sales call before you can do a real cost comparison against competitors.
- APR range tops out at 35.9%, meaning customers with weaker credit get expensive offers that may hurt close rates.
- The platform does nothing beyond financing, so contractors still need separate software for scheduling, invoicing, and job management.
- Specific integration partners are not named on the homepage, making it hard to confirm compatibility before starting a conversation with sales.

Frequently Asked Questions
How much does Wisetack cost for contractors?
Wisetack does not publish its merchant fee structure publicly. Contractors pay a transaction-based fee rather than a monthly subscription, but the exact percentage is disclosed during the sales process. You'll need to contact their team directly for a quote.
Does Wisetack integrate with HVAC and field service software?
Yes. Wisetack has API integrations with several field service management platforms, including Jobber and Housecall Pro, allowing contractors to send financing offers directly from their existing job management tools. The full integration list isn't published on their site, so it's worth confirming your specific software during onboarding.
Is Wisetack worth it for small HVAC or plumbing shops?
For shops with average tickets above $1,500, Wisetack can meaningfully improve close rates by giving customers a monthly payment option instead of a large upfront charge. The trade-off is an undisclosed merchant fee on each financed job, so the math depends on your margin and average job size.
Does Wisetack have a free trial?
No free trial is advertised. Wisetack operates on a merchant fee model per transaction, so there's no traditional subscription to trial. You can request a demo or sales conversation through their website.
What APR do customers get through Wisetack?
Customer APRs range from 0% to 35.9% depending on creditworthiness. Wisetack offers 0% APR plans up to 24 months for qualified buyers. Customers with lower credit scores will see higher rates, which can reduce the appeal of the financing offer at the point of sale.
