The tools on this page are built for different buyers — Online businesses and developers, Small businesses and mobile merchants, Small to medium-sized businesses, and Large enterprises and global businesses. Match the tool to your stage rather than to the longest feature list.
Startups and small US teams (1–50 employees): prioritize fast self-serve setup, month-to-month billing, and a free or low-cost tier. You want something running this week, not a three-month rollout.
Mid-market (50–1,000 employees): the deciding factors are usually SSO, granular permissions, an open API, and integrations with the rest of your stack. Expect a security questionnaire and a 4–8 week evaluation.
Enterprise (1,000+): weight the contract, not the demo — uptime SLA with credits, named support with US-hours coverage, sandbox environments, migration assistance, and a clear roadmap commitment.
A practical shortlist method: pick two options from this list — typically Stripe and PayPal Zettle — run the same real workflow through both for two weeks, and score them on setup time, support responsiveness, and how much manual work is left over.
