3 Best Merchant of Record Solutions for SaaS Startups
/3 Best Merchant of Record Solutions for SaaS Startups
Most SaaS founders don't realize how complex global payments are until they're already selling in five countries and have no idea what VAT they owe. The best Merchant of Record solutions solve that problem by taking on legal and financial liability so you don't have to. Managing chargebacks, staying current on PCI DSS requirements, and correctly remitting VAT and GST across dozens of jurisdictions is a full-time job. After reviewing platforms across the space, this guide covers three options worth serious consideration for any digital product business going global.
How the picks were chosen
Public information drove every decision here: user reviews, published case studies, feature documentation from official websites, and data pulled from software directories. Only platforms with a real track record in the Merchant of Record space made the cut.

● Fungies.io - Best for game studios, SaaS founders, and indie developers selling digital products
● Lemon Squeezy - Best for software companies and digital creators

Why Merchant Of Record Solutions Are Worth the Investment
Selling digital products internationally sounds straightforward until you're staring down VAT obligations in the EU, GST in Australia, and sales tax across 50 US states, all at the same time. Getting that wrong means penalties, back payments, and the kind of legal headaches that derail early-stage companies fast.
The right Merchant of Record takes all of that off your plate. They own the liability, file the taxes, fight the chargebacks, and keep your accounts in good standing with payment networks.
That kind of coverage is rare to build in-house without high costs. From a business outcomes perspective, it pays off directly: better chargeback ratios, higher payment authorization rates, and lower checkout abandonment because customers trust what they're seeing.

1. Fungies.io - Best for Digital Product Creators Who Want to Keep More Revenue
What Purpose Does Fungies.io Serve?
Fungies.io is a Merchant of Record platform for SaaS companies and digital businesses selling globally. They handle VAT and GST collection, sales tax compliance, fraud prevention, chargebacks, and refunds so SaaS companies and digital businesses can sell software, subscriptions, and digital products directly without building any payment infrastructure from scratch. Their pricing runs at 5% plus 50 cents per transaction, with no monthly or setup fees.
Why Pick Fungies.io for Merchant Of Record Solutions?
Fungies.io solves one of the most painful problems in digital sales: the gap between wanting to sell globally and actually being set up to do it legally and compliantly. Their commission-only model means they only earn when a business does, which tends to align incentives well for companies operating in regulated or compliance-heavy industries.
The Review Roundup:
From what customer feedback shows, clients like the platform's fast setup, responsive support, and ability to support growth without adding operational burden. Customers featured include Leadsin.io, Freevocals.com, TextToVideo.bot, and RenderAI.app - a good example of the kind of SaaS and digital businesses the platform supports.
2. Lemon Squeezy - Best for Software Companies Needing End-to-End Tax Coverage
What Purpose Does Lemon Squeezy Serve?
Lemon Squeezy is a payment and subscription platform built for software products. As a Merchant of Record, they cover VAT and sales tax filing across 200+ countries, support 130+ currencies, and include fraud detection on every transaction. The platform also handles license key management automatically, which is genuinely useful for software sellers who would otherwise piece that together separately. Their fee structure mirrors Fungies.io: 5% plus 50 cents per transaction, with no monthly commitments required.
Why Pick Lemon Squeezy for Merchant Of Record Solutions?
Lemon Squeezy covers the full compliance burden for software companies, from automated tax collection to payment recovery and fraud detection, without requiring any custom infrastructure. Their acquisition by Stripe in July 2024 adds a level of stability and technical backing that's hard to match at this price point, and that kind of institutional backing usually means the platform isn't going anywhere.
The Review Roundup:
The platform hit $1 million in annual recurring revenue within nine months of launching publicly, which says a lot about early product-market fit. Users consistently point to the ease of setup and the breadth of currency support as standout qualities. The developer-friendly REST API and webhook support also get regular praise from technical teams.
3. Polar - Best for AI Startups with Complex Usage-Based Billing Needs
What Purpose Does Polar Serve?
Polar is a billing infrastructure platform built for AI and SaaS companies that need to charge based on usage, tokens, API calls, compute time, or seat counts. They act as a Merchant of Record, covering sales tax and VAT compliance, receipts, dunning, and customer account management. What sets them apart is the built-in analytics layer: real-time event ingestion combined with unit economics visibility gives finance and product teams actual insight into how revenue relates to usage. They're also open-source, which is still pretty rare in the billing space.
Why Pick Polar for Merchant Of Record Solutions?
Polar removes the need to build and maintain custom billing logic for AI products, where pricing models are often too event-driven or detailed for off-the-shelf subscription tools to handle cleanly. Their $10M seed round led by Accel in June 2025 signals strong investor confidence, and that kind of early backing usually accelerates product development faster than bootstrapped alternatives can match.
The Review Roundup:
Polar has built a following among technically sophisticated teams, with endorsements from leaders at Vercel, FastAPI, and Ghostty backing their positioning. Clients like Tailwind Labs and Midday point to the real-time analytics and flexible billing architecture as the main draws. The open-source model and community-first approach feel genuinely different from how most billing platforms operate.
Selection Framework: How Each Pick Was Evaluated
The goal was to find Merchant of Record platforms that genuinely serve digital product businesses, not just ones with polished marketing sites. Here's how the research was structured.
What Data Should Be Collected First
The starting point was building a broad list of Merchant of Record platforms from software directories, community forums, and SaaS-focused review platforms. Published case studies, product documentation, and announcements from each company were gathered alongside that directory data. This initial pass prioritized breadth over filtering, since the goal was to capture any platform with real traction in the space before narrowing down.
Filtering Candidates to Your Requirements
Once a longlist was assembled, options without verifiable user activity were removed. Platforms with thin or unverifiable review histories, no published client examples, and no clear documentation of their tax and compliance coverage were cut at this stage. Review patterns were analyzed across multiple sources rather than relying on any single directory score, since individual ratings can be noisy without cross-referencing.
Claims Are Fact-Checked Against Reliable Sources
Each platform's stated capabilities, including geographic coverage, fee structures, and compliance scope, were cross-checked against public documentation and third-party commentary. Where a company's marketing described a capability, independent sources were checked to confirm whether real-world users reported the same experience. Discrepancies between stated features and user-reported outcomes were noted and weighed in the final evaluation.
Industry Standing Check
Signals of credibility beyond self-reported data were also reviewed. This included funding announcements, acquisitions, mentions in respected industry publications, and partnerships or customer endorsements from recognized names in the space. Lemon Squeezy's acquisition by Stripe and Polar's seed round led by Accel both surfaced through this check, and both are meaningful signals that the broader market is paying attention.
Real-World Merchant Of Record Solutions Evidence
Finally, each platform was evaluated for evidence of actual Merchant of Record activity, not just in positioning. This meant looking for dedicated service pages covering tax remittance, chargeback management, and compliance processes, as well as verified client stories describing specific outcomes. Fungies.io's Findgu case study, Lemon Squeezy's documented revenue milestones, and Polar's named client roster all qualified as real-world evidence rather than generic claims.
Choosing the Right Merchant Of Record Solutions: A Quick Guide
Picking a Merchant of Record isn't just a billing decision. It's a legal and financial one too, so the criteria go well beyond features and price.
● Industry/Domain Experience: Look for platforms that have worked with companies in your category, whether that's SaaS, digital goods, AI tooling, or games. Experience with your specific billing model matters more than general payment experience.
● Features and Service: Check what's actually included: tax remittance, chargeback handling, fraud detection, multi-currency support, and dunning management. Some platforms bundle these; others charge separately.
● Pricing Structure: Commission-only models (like 5% plus 50 cents) can be more startup-friendly than platforms charging flat monthly fees on top of per-transaction costs. Run the numbers at your expected transaction volume.
● Results Measurement: Ask how each platform reports on payment authorization rates, failed payment recovery, and chargeback ratios. If they can't show you those numbers, that's a signal worth taking seriously.
● Industry Knowledge and Compliance: Global tax law changes constantly. Make sure your chosen platform actively maintains compliance coverage across the regions you sell in, not just the ones they list on a landing page.
Wrapping Up
Choosing the right Merchant of Record comes down to fit: your billing model, your target markets, and how much tax and compliance work you're ready to hand off. Fungies.io suits digital product creators who want low fees and simple setup. Lemon Squeezy fits software companies that need broad global coverage. Polar is built for AI startups with event-driven pricing. As digital product businesses expand internationally, getting this layer of infrastructure right early will matter more than most founders expect.
