Wisetack Review: Financing Countertop Customers in 2026

Wisetack Review: Financing Countertop Customers in 2026

A homeowner stares at a $12,400 quartzite quote. Cash is not happening. The shop loses the deal to a competitor who offered $345 a month over 36 months. That is the math Wisetack solves, and it is the reason point-of-sale financing has gone from a luxury feature to table stakes in the trades.

This is a working review of Wisetack from a stone shop perspective. The full breakdown: how it works, what it costs the shop, what it costs the customer, where it pays off, where it does not, and how it stacks against the alternatives.

The article sits in the Stone Shop Tech Stack & Integrations cluster, part of the Complete Guide to Countertop Fabrication. For the head-to-head with Sunbit specifically, see Wisetack vs Sunbit.

What Wisetack Is

Wisetack is a point-of-sale consumer lender for the home services trades. Founded in 2018, San Francisco-based, backed by Greylock, Bain Capital Ventures, and others. The company has lent to over 1 million home-service customers as of 2025.

The product:

• Customer applies via text or QR code at quote time.
• Wisetack runs a soft credit check (does not affect the customer's score).
• Approval decision in seconds.
• Customer picks a term and signs the loan agreement.
• Shop is paid in full minus a merchant fee, typically 24 to 48 hours after install.
• Customer pays Wisetack monthly. Shop has no exposure if the customer defaults.

The pitch is straightforward: turn a no-cash customer into a yes-monthly-payment customer, get paid in full, no chargebacks, no recourse.

Wisetack's Numbers

The company publishes some operational metrics:

• Average loan size in home services runs $2,500 to $7,500, with the upper bound for stone shops, roofers, and HVAC.
• Approval rate sits around 70 to 80 percent for the typical home-services applicant base.
• Funding to the shop usually happens within 1 to 2 business days of install completion.
• Loan terms available: 3, 6, 12, 24, 36, 60 months.
• Loan amounts: up to $25,000.
• Customer APR: 0 percent for promotional terms, up to about 36 percent on the longer terms with lower-credit applicants.
• Merchant fee paid by the shop: 3 to 8 percent on most promotions, sometimes higher for the 0 percent customer APR offers.

How It Works In A Stone Shop

The integration pattern that works:

• Quote is built in Slabwise (or whatever quoting tool the shop uses).
• The quote total includes a financing line: "or $278/month for 36 months with approved credit."
• Customer sees the monthly payment alongside the cash price.
• Customer texts the application link from the shop's branded page.
• Wisetack runs the soft pull. Decision in seconds.
• If approved, the customer signs the loan agreement on their phone.
• Shop collects the signed loan agreement and the signed shop contract.
• Job moves into production.
• On install completion, the shop submits the completion notice to Wisetack.
• Wisetack disburses to the shop's bank account, minus the merchant fee.

For the shop, the workflow inside Slabwise looks like a normal job with the financing fee tracked as a separate line item that flows to QuickBooks as a financing expense.

What Wisetack Charges The Shop

Merchant fees vary based on:

• The customer APR offered (0 percent customer APR costs the shop more in merchant fees).
• The shop's volume history.
• The loan term length.

Working ranges as of 2026:

• 0 percent customer APR, 12-month term: Merchant fee around 5.99 to 8.99 percent.
• 0 percent customer APR, 24-month term: Merchant fee around 7.99 to 12.99 percent.
• Standard customer APR offers (8 to 24 percent customer rate): Merchant fee around 2.99 to 4.99 percent.
• Subprime applicant accepted at higher customer APR: Merchant fee around 2.99 to 4.99 percent.

The shop chooses which promotions to offer. Most stone shops run a default offer (something like 6.99 percent merchant fee, 12 months at 0 percent customer APR) and have a backup promo (longer term, higher merchant fee) for customers who cannot fit the monthly payment.

What Wisetack Charges The Customer

Customer APR varies based on credit. The honest ranges:

• Prime credit customer (740+): Often 0 percent on shorter terms, 6 to 14 percent on longer terms.
• Near-prime customer (680-739): 8 to 22 percent depending on term.
• Subprime customer (below 680): 22 to 36 percent.

Wisetack's customer-facing promise is "no surprises", the rate the customer agrees to at signup does not change. No fees beyond the loan agreement. Customers can pay off early without penalty in most loan products.

Where Wisetack Pays Off For Stone Shops

The clearest wins:

The save on a price-sensitive customer. Customer is about to walk because the cash quote feels too big. Sales rep offers the monthly payment. Deal closes. Without the financing offer, this deal is gone. The 6 to 8 percent merchant fee is the cost of closing a deal that was otherwise lost.

The upgrade path. Customer was budgeting $7K. Financing converts the conversation to "for $20 more a month, you can have the quartzite instead of the quartz." Average ticket goes up.

Faster cash flow. Customer financing pays the shop in 1 to 2 days post-install. Compared to a customer who pays half on signing and half on install, the cash conversion cycle is roughly the same but with zero collections risk.

No collections work. Default risk sits with Wisetack, not the shop. The shop never chases a payment.

Where Wisetack Does Not Pay Off

The places where shops misuse the tool:

Defaulting every customer into financing. Customers who were going to pay cash get offered financing, agree, and the shop loses 6 percent in merchant fees that would have been clean revenue. Financing should be a save tool for hesitating customers, not a default for everyone.

Hiding the fee in the quote. Some shops pad the cash price to cover the financing fee, then offer "no financing fee" pricing. This is technically against Wisetack's terms and can get the merchant account suspended.

Underpricing the job to hit the financing payment. Customer says "I can do $400 a month max." Sales rep adjusts the job to fit. Now the shop is selling at a discount and paying a financing fee. The math gets bad fast.

Not training the sales team on disclosure. Federal lending disclosure rules apply. Shops have to handle the customer conversation correctly to stay compliant.

How Wisetack Compares To Alternatives

For the head-to-head against Sunbit, see Wisetack vs Sunbit. The shorter summary against other alternatives:

Synchrony Home Design (formerly GE Capital): Card-based financing, longer underwriting, less consumer-friendly app. Stronger for very large jobs ($25K+), weaker for the $5K to $15K range that most stone jobs sit in.

GreenSky: Solid alternative, often used by HVAC and home improvement. Pricing similar to Wisetack on merchant fees. Customer experience is closer to a traditional bank loan.

Affirm: More consumer-direct, less trades-focused. Higher friction on the shop side. Better fit for retail than for trades.

Klarna or Afterpay: Built for retail BNPL on small purchases. Not the right fit for $10K kitchens.

The honest field for stone shops is essentially Wisetack, Sunbit, and Synchrony. The first two compete head-to-head; Synchrony is the option for shops with established lender relationships.

The Slabwise Position On Wisetack

Slabwise is a shop platform, not a lender. Customer financing is an integration the platform supports because financing genuinely closes more kitchens for our shop customers.

The pattern we recommend:

• Use the financing offer as a closing tool inside the quote workflow.
• Train the sales team to offer it as a save, not a default.
• Track the close rate on financed jobs versus cash jobs in the platform so the math is visible.
• Offer Wisetack as the primary option, with Sunbit available as a backup for customers Wisetack declines.
• Code the merchant fee as a financing expense in QuickBooks so gross margin reporting stays accurate.

For shops doing $1M+ in revenue, customer financing typically adds 8 to 15 percent to closed revenue. The math is real, and the platform makes it easy to operate without the discipline gaps that plague shops trying to run financing on a spreadsheet.

The Shop Math On Wisetack

For a $2M stone shop closing 250 jobs a year, run the conservative model:

• 30 percent of customers offered financing accept it. That is 75 financed jobs.
• Average financed job: $8,500. Total financed revenue: $637,500.
• Merchant fee blended average: 5.5 percent. Total fees paid: about $35,000.
• Close rate lift from offering financing: typically 10 to 15 percent on flagged customers. Working number: 20 incremental jobs that would have been lost without financing.
• Incremental revenue captured: 20 jobs at $8,500 = $170,000.
• Net margin on the incremental revenue at 30 percent gross margin: $51,000.

The merchant fees are a real cost. The incremental closed revenue from offering financing more than covers them. The math works out positive in the typical case.

Common Wisetack Setup Mistakes

Five places where shops trip up:

Not registering the merchant account early enough. Wisetack underwrites the shop before allowing live offers. Plan for 1 to 2 weeks of setup before going live.

Skipping the sales training. The sales team has to know how to present the offer, how to disclose, and how to handle declines. Without training the close rate lift does not materialize.

Offering the highest merchant fee promo by default. The 0 percent customer APR 24-month offer is the most expensive promo. Save it for the customers who need it; default to a cheaper promo.

Letting customers shop the financing offer separately. The customer signs the financing first, then walks to a competitor with the financed budget. Tie the financing approval to the shop's contract signature.

Not tracking the financing-tagged data. Without tagging financed jobs in Slabwise or QuickBooks, the shop has no idea whether financing is paying off. Tag everything.

FAQ

How does Wisetack make money? Two ways. The merchant fee charged to the shop, and interest charged to customers on the longer-term loans. Wisetack carries the credit risk in exchange.

Can a customer pay off the loan early? Yes, in most Wisetack loan products without penalty. Customers who pay off early end up with no interest on the 0 percent promo terms.

What is Wisetack's approval rate? Around 70 to 80 percent in the home services category. Higher than Synchrony in most segments, similar to GreenSky.

Does Wisetack do a hard credit pull? No. Application is a soft pull only. Hard pulls happen only if and when the loan is reported to credit bureaus after issuance, which is normal credit reporting behavior.

Does Wisetack work for commercial jobs? The product is designed for consumer financing. Commercial financing has different requirements and Wisetack is not the right tool there.

How much volume do I need to qualify for Wisetack? Wisetack onboards shops at any volume. The merchant fee tends to start higher for new shops and improve with track record.

What happens if a customer defaults? The shop has no exposure. Wisetack handles collections. The shop already received its payment after install.

Can I offer 0 percent APR to all my customers? Yes, but the merchant fee is higher on those promotions. Most shops offer 0 percent on shorter terms (12-month) and standard rates on longer terms (36-60 month) to balance the merchant fee cost.

Is the Slabwise integration deep enough? The integration ties financing offers to the quote, captures the loan agreement reference, and records the disbursement and fee. Shops can run financing as part of the normal job workflow without separate tools.
