Summary verdict
Miami-based Greenbox Capital provides alternative business funding from $3,000 to $500,000 (Greenbox). RealReviews gives it 7.5/10, praising speed and advisors while raising questions about complete cost, renewal pricing, stacking fees and collections (RealReviews).
Paper Grade: D paper
Greenbox's minimums are $10,000 a month in revenue, 5+ months in business and a 500+ FICO (soft pull). It also offers second-position funding with 3–9 month terms (Greenbox). Very young businesses, low credit and stacked positions make it D paper. Paper grade describes the borrower profile this lender targets, not the lender's quality.
Research-Based Reputation Score: 7.5 / 10 (reputation rank: tied #16 of 72 lenders scored, as of October 2, 2026)
How we got there: start at 5.0, then +0.5 for Trustpilot at 4.0/5 from 581 reviews per RealReviews (RealReviews), +1 for BBB accreditation (since May 5, 2014) with an A+ (BBB), +1 because BBB lists the business as started in 2012, and +1 because we found no regulator orders or court judgments against it. Individual suits appear in court records and are not scored. Then −1 for recurring themes documented by RealReviews, including cost, early payoff, stacking fees, aftercare and collections (RealReviews). BBB shows 2 complaints in three years (BBB complaints).
About the Paper Grade: it reflects only the borrower profile and deal type the lender targets (stated credit, time-in-business and revenue minimums, and product type). It is not a judgment of the lender's quality. A = strong credit (about 625–650+), established businesses, APR-priced loans or lines. B = fair credit (about 600+), short-term or factor-rate products. C = credit about 500–599, younger businesses, MCA or revenue-based, or sales-based platform financing with no credit check. D = minimal credit requirements, very new businesses, stacked positions or high-risk industries. Lawsuits and regulator actions never change the Paper Grade.
About the Research-Based Reputation Score (1–10, half-points): it summarizes public signals and is not the opinion of MCAFax. Every lender starts at 5.0. Points are added for BBB accreditation and an A+ rating, years in business, strong Trustpilot ratings, and a clean record (no regulator orders or court judgments in which the lender itself is a named party). Points are subtracted for a BBB rating of C− or lower (−1), a BBB customer-review average below 2.5/5 (−0.5), recurring complaint themes (−0.5 to −1), and a pending class action (−0.5). Government actions are scored only when the lender itself is a named party: −1 for a settled action not about borrowers, −2 for a regulator consent order with a penalty and no admission, −3 for active enforcement or a final order about borrower treatment, and −5 for an industry ban or court finding of liability. The lowest score, 1.0, is reserved for lenders under an industry ban or a final fraud judgment. Ratings we could not read score zero, and routine collection suits are not scored. Every point applied to this lender is listed above. Ranks are as of the date shown; MCAFax cannot confirm or deny any allegation counted here.

What borrowers and reviewers report
Positive themes: fast funding and helpful named advisors (RealReviews).
Negative themes: RealReviews says recent detailed reviews raise "material questions about complete cost, renewal pricing, early payoff, stacking fees, post-funding service and collections" (RealReviews).
Reported concerns to plan around
These are allegations or reported experiences, not findings, unless a final order is cited.
- Second position: if you already have an advance, a second-position deal adds a second daily or weekly debit. Model both payments together before signing.
Who it may suit, and who may want to skip it
May suit: young, lower-credit businesses that need small amounts quickly. May want to skip: businesses already strained by an existing advance.
