A working archive of merchant services guides — plain-language explainers on TSYS, Global Payments, agent programs, merchant portals, POS systems and the wider payment processing industry. Each guide is written from primary sources, reviewed by the editorial team before publishing, and updated as underlying facts change.
Background on TSYS: its history, its acquisition by Global Payments, and what services the platform actually provides today.
Practical walkthrough of what it takes to build a book of business as a TSYS or Global Payments sub-ISO agent.
Side-by-side comparison of TSYS (now Global Payments) and First Data (now Fiserv) — platforms, pricing philosophies, agent programs.
How TSYS-platform agent compensation is calculated, how contracts vary, and how to think about portfolio economics over five years.
Our merchant services guides fall into four broad categories, each designed to answer a different reader's question. Knowing which category you're in helps you find the right guide faster.
Guides like What is TSYS? cover the companies, history and structure of the merchant services industry. Useful when a reader encounters a processor name in a contract or marketing pitch and wants to understand who actually operates the underlying platform. Common reader: a small-business owner evaluating a sales pitch, or a new agent orienting themselves to the industry.
Guides like How to become a TSYS agent and TSYS agent commission guide cover the practical mechanics of becoming a merchant services agent — contract terms to fight for, realistic year-one income expectations, how residuals actually compound over five years, and what "portfolio ownership" really means in this industry.
Guides like TSYS vs First Data compare competing platforms and vendors side by side. These are the most-searched guides in the space because every merchant and every agent is comparison-shopping sooner or later. Our comparisons focus on concrete differences in platform capability, agent program terms, and pricing philosophy rather than marketing claims.
Across the main site, guides like the small business payments playbook, merchant portal explainer and payment reporting walkthrough cover day-to-day operational topics — reading statements, handling chargebacks, setting up reporting exports, choosing a POS system, understanding PCI compliance.
Every merchant services guide on Agent Portal TSYS is drafted from primary sources — card-brand rate schedules (Visa, Mastercard, Discover), PCI Security Standards Council bulletins, Federal Reserve Regulation II documentation, and publicly filed SEC documents from Global Payments Inc. and Fiserv Inc. We do not republish vendor marketing, sponsored content or press releases as editorial. When we reference a specific company or product, we describe what it actually does based on our independent review, not what its sales deck claims.
Articles are reviewed by a second member of the editorial team before publishing and re-reviewed on a rolling basis. The "reviewed" date at the top of each guide reflects the most recent editorial pass, which is also when we verify that specific claims (rate schedules, URL references, product names) still hold. Substantive corrections are implemented promptly with a dated note indicating what changed.
For definitions of technical terms referenced across our guides, see the merchant services glossary. For published interchange rates, see the interchange categories reference.
Merchant services is a big industry with hundreds of sub-topics, and we can't cover all of them well. Three filters decide what we write about: reader demand (what questions come into our editorial desk most often), information gap (where existing coverage is thin, misleading, or purely promotional), and editorial capacity (topics we can cover with primary-source depth rather than surface-level summary). The archive above represents the intersection of those three filters.
Every reader arrives at a merchant services resource with a different starting question. We've organized suggested reading paths below for the four reader types we see most often.
Start with the small business payments playbook — it covers statement literacy, the three components of processing cost, and how to evaluate competing processor quotes. Then read the merchant portal explainer to understand what your portal shows and where to find statements, chargebacks, and deposit confirmations. If you're negotiating or re-shopping your processor, the interchange categories reference gives you concrete rate anchors for the conversation.
Start with What is TSYS? for industry context, then How to become a TSYS agent for the practical path. Read the commission guide before you sign anything — specifically the sections on contract terms, portfolio ownership, and five-year lifetime value. The partner programs overview explains the structural differences between ISO, sub-ISO, agent, ISV and referral relationships.
The TSYS agent login guide and agent login directory cover portal access and residual report reading. The commission guide includes the five-year LTV modeling and portfolio valuation multiples most agents want to understand before selling or negotiating. Comparison material: TSYS vs First Data helps agents working across multiple platforms contextualize the differences.
The payments primer and interchange reference are the most-shareable resources for educating customers or team members. Vertical content (solutions by industry, POS systems) is useful for sales conversations. The glossary is deliberately designed for easy linking from other educational content.
