User Reviews

What users are saying about these tools
Reviews Winner
Engine
BILL
2.50 reviews

BILL receives significantly negative feedback on Trustpilot (2.5/5), contradicting its strong internal promises of efficiency. The most prevalent complaint is the critically nonexistent customer support.

Users report spending hours locked behind slow, unhelpful chat bots, often unable to solve basic access or payment issues. Reliability is a major concern, particularly with payments; users frequently mention significant delays in ACH/ePayments (3–4 business days), alleging the company intentionally holds funds to earn interest.

1.0 / 5

It’s basically impossible to get any support on this platform. I spent weeks just trying to get account access back. You are locked behind chat that is useless and told me three times they had resolved the issue when they hadn't.

Engine

Our Verdict

Objective guidance based on features, pricing, and overall fit.

It consolidates bookings, billing, and reporting for teams. Users love the cost savings and ease of use. The deciding factor is your business pain point. If you struggle with manual financial work, BILL addresses that. If you juggle multiple travel vendors and expenses, Engine solves that. Choose BILL if you need to automate AP/AR and have a budget for per-user pricing. Choose Engine if you want to manage business travel for free. They aren't competitors—they're tools for different jobs.
