Wisetack vs GreenSky vs Synchrony: what’s actually different?
Mustang offers all three. The real differences aren’t about who approves more people — none of them can promise that — they’re about who’s actually lending the money and whether you’re comparing a fixed payment or a promotion with a deadline.

All three check your credit and decide on their own, but the money doesn’t come from the same place. Wisetack says checking your eligibility has “no impact” on your credit score, and the actual loan comes from one of its unnamed “lending partners.” GreenSky says in writing that it is not the lender itself; a federally insured bank funds the loan and GreenSky services it. Synchrony is itself a bank (Synchrony Bank, FDIC-insured) and runs its fence/gate financing as a promotional retail financing card — currently 0% APR for up to 18 months for qualified applicants, per Mustang’s financing page.

Who’s actually lending the money
“Financing through Mustang” means three different company structures, by each company’s own description. Wisetack is the application layer; its page says the money itself is “provided by our lending partners,” without naming them — ask which one at application. GreenSky states plainly it is “not a lender,” and that loans are “offered and made by federally insured, federal or state chartered financial institutions,” with GreenSky handling origination and servicing. Synchrony is different: it is itself a bank, and its consumer financing runs through its own retail credit card programs.
None of that changes how approval works. Each one checks your credit report and your information, and decides on its own; no lender can promise a result before you apply.
A fixed payment vs. a promotion with a deadline
Wisetack frames its own offers around “choose the monthly payment that works best,” and GreenSky’s structure (a bank-funded installment loan) works the same way: once approved, you’re looking at a set payment and term. Synchrony’s side of Mustang’s financing is a promotion — Mustang’s financing page states qualified applicants can get 0% APR for up to 18 months. A promotion like that can be structured as true 0% (no interest for the period, whatever is left afterward) or as deferred interest, where the CFPB says a balance left at the end, or a payment over 60 days late, usually brings back interest calculated from the purchase date. Ask Synchrony in writing which kind applies before you sign anything.
Which lender to ask about first
Tick whatever matters to you. This points you to a starting question for your estimate call, not an approval or a rate — each lender still decides on its own after you apply.
Based on each lender’s own consumer-facing statements (greensky.com, wisetack.com/consumers, synchrony.com/about-us.html, all read 2026-10-19) and Mustang’s financing page. Terms, rates and approval are set by the lender when you apply.
