Fullsteam Review

Fullsteam is a payments and vertical-software holding company founded in 2018 and headquartered in Auburn, Alabama, with a second base in Atlanta. Its model is unusual enough to explain before anything else: rather than selling merchant accounts directly, Fullsteam buys the industry-specific software small businesses already run on — association management, self-storage, field services, healthcare practice management, automotive, wine, hospitality — and embeds its own payment processing into those products. It registered as a Visa payment facilitator in 2019, and by its own account it now employs more than 2,100 people and serves over 60,000 customers, having acquired dozens of software businesses since 2018. For a merchant, that means Fullsteam is usually not a company you chose. It is the company that started processing your payments after the software vendor you did choose was acquired. The product side of that bargain is real: modern embedded payments, one support and reporting layer, and back-office scale a small software vendor could not fund. The commercial side is where the criticism sits. Fullsteam publishes no pricing at all, and a payments-audit firm has documented five rate increases since May 2023, most recently in April 2026.

A software roll-up that happens to process payments

Fullsteam was founded in 2018, is headquartered in Auburn, Alabama with a second base in Atlanta, and is run by chief executive Michael Lawler. Its business is buying vertical-market software companies and embedding its own payment processing into the products those companies sell. It registered as a Visa payment facilitator in 2019 and has acquired steadily ever since — by its own account more than fifty software businesses by 2022 and eleven more in 2024 — reaching over 2,100 employees and more than 60,000 customers.

The verticals give a good sense of the strategy: association management, field services, self-storage, healthcare practice management, automotive, recreation, hospitality, wine, specialty retail, B2B ERP. These are markets too small to attract a Toast or a Square, served by software companies that were often founder-run and under-invested. Fullsteam buys them, funds the product, and takes the payments.

Why this matters to a merchant

Most companies on this site are chosen. Fullsteam usually is not. The typical merchant journey is that a software vendor they picked years ago gets acquired, and some months later the payment processing moves to Fullsteam. Nobody quoted them, nobody competed for the account, and the price was set by a company they had no relationship with.

That is not misconduct — it is how integrated payments work across the whole industry, and the software often genuinely improves under new ownership. But it removes the two things that normally keep processing prices honest: a competitive sale at the start, and an easy exit afterwards. Leaving Fullsteam's processing frequently means leaving the software as well, and replacing the system a business runs on is a much bigger decision than changing processors.

The pricing, as far as anyone outside can see it

Fullsteam publishes nothing: no rate, no monthly fee, no contract term, no cancellation policy. What public information exists comes from Merchant Cost Consulting, a payments-audit firm that reads client statements and publishes what it finds. Its figures are one firm's observations rather than disclosed pricing, and this review treats them as attributed reporting — but they are specific and they are the only numbers available.

It reports an average markup of about 0.40% over interchange, ranging from roughly 0.10% to 1.05% depending largely on which Fullsteam-owned brand the merchant signed with. It records rate increases effective 1 May 2023 and 1 October 2023, each of 0.14% plus $0.14 per transaction, with the October round adding a partner-of-processing-cost fee of 0.02% plus two cents; 1 April 2024 at 0.09% plus $0.09; 5 April 2025 at 0.072% plus a cent, alongside a new daily gross funding fee of 0.05% of volume and a $4.95 monthly rise in the PCI non-compliance charge; and 1 April 2026 at either 0.10% or 0.0338% plus three cents depending on the merchant, together with a further 0.02% on daily gross funding and a $30 rise in the PCI non-compliance fee. Alongside these it cites PCI breach-protection charges of roughly $14.95 to $19.95 a month, PCI non-compliance charges of roughly $34.95 to $69.95 a month, accelerated funding around $20 a month, and a daily gross funding fee of 0.05% to 0.07% of volume.

The most damaging observation in that audit is not any single number. It is that the effective rate a merchant is paying does not appear on the statement at all, and that working it out takes three consecutive months of statements. A price that cannot be read is a price that cannot be challenged.

What about the complaint record?

There is less here than a search suggests, and the confusion is worth clearing up. The Better Business Bureau profile that surfaces for Fullsteam in Auburn belongs to StarChapter, an association-management product in the portfolio, filed under the alternate name Fullsteam Software Holdings, LLC; it carries a C- for failing to respond to a single complaint. A separate BBB profile for a Californian insurance brokerage with a similar name is a different company entirely and has nothing to do with this one. Neither describes Fullsteam's payments business.

That is a consequence of the structure rather than a clean bill of health. Because the group operates dozens of separately branded products, merchant sentiment is scattered across dozens of small review surfaces and there is no single reputation to read. Diligence here means researching the specific brand you use, not the parent.

How to handle a Fullsteam account

Audit annually, and do it in April. Pull three consecutive statements, total every fee including the daily gross funding line and the PCI charges, divide by volume and write down your effective rate. Then get an interchange-plus quote from an independent processor for the same volume and mix, and use the difference as a negotiating position rather than as a reason to leave — because leaving may not be available.

Before any of that, establish two facts in writing: whether your Fullsteam-owned software will work with an outside processor and at what cost, and whether the software subscription and the processing agreement can be cancelled independently. Those two answers determine whether you have a negotiation or an announcement.

The verdict

B-. Fullsteam is a substantial and competent company that has put real money into software niches that were starved of it, and the embedded-payments experience it delivers is better than the bolted-on integrations it replaced. It is graded down for the commercial side of the same model: no published pricing anywhere, a documented run of near-annual increases, statements that obscure the effective rate, and pricing that varies by which brand acquired you rather than by anything about your business. If you are on a Fullsteam product and it works, stay — and treat the price as something you have to check every April, because nobody is going to show it to you.
