Key takeaways
- The standard SaaS marketing advice for solo founders is sound — it just assumes you're already set up to take a US customer's money. Pick two or three channels, run them for twelve months, ignore the rest. Good advice. But it starts one step after the step most first-time founders haven't finished.
- The channel you pick doesn't only decide where customers come from — it decides who the seller of record is. The seller of record is the business a sale legally belongs to, and that's what determines who registers for, collects, and remits sales tax or VAT.
- Some channels take that job off your plate; one channel hands it entirely to you. Sell through the App Store, Google Play, or a marketplace like AppSumo, and the platform is usually the seller (or merchant) of record. Sell direct through your own Stripe checkout, and every bit of it is yours.
- This hits non-US, first-time founders hardest. Going direct makes you the seller of record in a country with dozens of separate state rulebooks you've probably never read.
- So before you commit to your 2–3 channels, map each one to "who's the seller of record." It's a distribution and compliance decision wearing a marketing hat.
SaaS marketing for solo founders: the advice everyone agrees on (and the step it skips)
Search saas marketing for solo founders and you'll get a remarkably consistent answer. The standard playbook — the one you'll find in guides like scribepilot's, and in a dozen "how I got to $1M solo" essays — says roughly this: you can't run eleven channels alone, so pick two or three and commit to them for twelve months or more. The usual shortlist is some mix of content and SEO, a community or audience play, paid search, an AppSumo or lifetime-deal launch, a Product Hunt moment, influencer or newsletter sponsorships, cold outbound, and a freemium or free-trial funnel to convert the traffic. Focus beats spread; consistency beats novelty.
None of that is wrong. It's the most useful marketing advice a one-person SaaS can follow, and this brief isn't here to argue with it.
Here's the step it skips. Every one of those channels assumes you already have a working answer to a plain question: when a customer in Texas or New York clicks "subscribe," who does that sale legally belong to, and who owes the tax on it? The playbook treats "get customers" and "get paid" as the same move. For a founder in the US who incorporated last year, they nearly are. For a first-time or non-US founder, they are two completely different problems — and the second one is decided, quietly, by the marketing channel you chose to solve the first.
That's the layer under the playbook. Not more channels — the plumbing beneath the ones you already picked.
Your marketing channel is also a tax decision
Start with a definition, because the whole thing turns on it. The seller of record is the entity a transaction legally belongs to — the "store" the customer bought from, as far as a tax authority is concerned. Whoever that is has to register for, collect, and remit sales tax (in the US) or VAT/GST (elsewhere) on the sale. A related term you'll see is merchant of record (MoR): a provider that deliberately becomes the seller of record for you and takes the tax work with it.
Now the part the marketing guides leave out: how solo founders sell their SaaS decides who that seller of record is. The channel isn't just a faucet for traffic. Distribution channels — app stores, marketplaces, your own checkout — each sit in a different place on the seller-of-record question, and the differences are large.
| Channel | Who's usually the seller of record | Who typically handles the sales tax / VAT | What's left on you |
|---|---|---|---|
| Apple App Store / Google Play | Apple or Google, acting as the merchant of record for most transactions | The platform calculates, collects, and remits based on the buyer's location, in most cases | Your income tax on the payouts; possibly registration or a $0 filing in some states once you cross a threshold |
| Marketplace / lifetime deal (AppSumo, Amazon, Etsy) | The platform, as facilitator or reseller of that sale | The platform generally handles the tax on the sales it facilitates | Income tax on your cut; whatever the platform's terms don't cover — read them |
| Your own site + standard Stripe checkout | You | You — register, collect, and remit once you cross a state's threshold | Everything: registration, collection, remittance, filing, plus your income tax |
| Your own site + a merchant-of-record service (Paddle, or Stripe's MoR option) | The MoR provider | The provider becomes seller of record and handles sales tax / VAT | Income tax on your payouts; you trade a fee for offloading the tax operations |
| Promotion-only channels (SEO, Google Ads, Product Hunt, cold email) | Whoever your checkout is — usually still you | Same as your checkout above | Your checkout's obligations, plus channel-specific rules (cold email, see below) |
Read down the "who's the seller of record" column and the pattern is hard to miss. The channels the playbook loves for their reach — the App Store, an AppSumo launch — happen to be the ones that quietly take the tax job off your desk, because the platform is the store and you're the supplier behind it. The channel it loves for its margin — your own site with a raw Stripe checkout, no platform cut — is the one that makes you the store, and hands you the entire compliance stack that comes with it.
Note the hedges in that table on purpose: platform tax handling varies by product type, region, and the platform's current terms, and it changes. Treat the table as the shape of the decision, not a substitute for reading each platform's tax policy and confirming your own case with a professional. The point isn't the exact mechanics of any one row — it's that choosing a channel is choosing a row.
Who this hits hardest
If you're a US founder who already has an entity and a business bank account, this is mostly bookkeeping: you know you're the seller of record on your own site, and your accountant watches the thresholds.
The people this catches are non-US and first-time solo founders selling direct. Two things stack up on them at once. First, they're the most likely to reach for their own storefront with a plain Stripe checkout, because the guides praise it — no platform cut, full control, "own your funnel." Second, doing exactly that makes them the seller of record in the United States, a country with no single national sales tax and dozens of separate state rulebooks, none of which they've read. Being based abroad isn't an exemption; US sales-tax obligations follow how much you sell into each state, not where you sit. We walk through where that line actually falls in do foreign sellers have to collect US sales tax — the short version is that it depends on crossing each state's economic-nexus threshold, and marketplaces already collect on the sales they facilitate while your own store is yours.
The cruel part is that the app-store and marketplace channels — the ones that would have shielded a beginner from most of this — are often the ones a "own your margin" essay talks them out of. The founder optimizes for the highest-margin channel and, without noticing, opts into the highest-compliance one. This is the same real-world layer that automation keeps running into: software can build and market the product, but it can't decide who the sale legally belongs to. We made that broader case in what AI still can't do for a one-person company, and the seller-of-record question is a clean example of it.
What to do before you commit to 2–3 channels
You don't need to solve US tax law. You need to make the channel decision with the seller-of-record question in view instead of discovering it after your first hundred sales. Four moves, in order:
- For every channel in your shortlist, find out who the seller of record is — before you commit. Open the platform's tax or payout terms (app stores, marketplaces, and MoR providers all publish them) and answer one question per channel: does this platform sell to the customer, or do I? That single answer tells you whether the tax work is yours.
- If you're selling direct, decide raw processor vs. merchant of record on purpose. A standard Stripe checkout keeps your margin and makes you the seller of record — registration, collection, and remittance land on you as your volume into each state grows. A merchant-of-record service (Paddle, or Stripe's MoR configuration, among others) becomes the seller of record and absorbs the sales-tax and VAT work in exchange for a fee — we walk through that processor-vs-MoR split, including Stripe's two modes, in does Stripe collect sales tax for you. Neither is "correct" — it's a trade between margin and operational load, and it's a choice, not a default. The threshold math that decides how heavy the direct route gets is in the economic-nexus brief.
- If you'll sell direct or ship an app, get the boring setup that verification needs. App Store and Google Play developer onboarding, Stripe, and a business bank account all ask for a real business entity and a real US business address, and then check them against each other. A home address you didn't mean to publish, or a PO Box a bank rejects, is where a launch stalls — not in the marketing.
- If cold email is one of your channels, US rules come with it. CAN-SPAM generally applies to commercial email sent to recipients in the US regardless of where the sender is based — meaning a working opt-out, honest subject lines, and clear identification of who's writing. As with the tax side, "marketing into the US" tends to drag US rules along with it; confirm the specifics for your program with counsel.
This brief is general information for founders, not legal, tax, or financial advice. Platform tax handling and seller-of-record rules vary by product, region, and provider and change often — confirm your own situation with a qualified tax professional and each platform's current terms before you rely on any of the above.
The setup angle: a real address sits under the whole thing
Whichever channels you pick, the moment you're the seller of record — your own checkout, or an app you publish — you inherit the same real-world dependency the marketing advice never mentions: a business that institutions can verify. A payment processor, an app-store developer account, and a business bank all want a genuine business entity and a genuine US business address, and they cross-check the two. That's the layer the channel decision lands on.
That address doesn't create a tax obligation on its own — a mail-forwarding address isn't inventory, staff, or an office — but it's what the verification steps behind "get paid" actually ask for. For founders selling into the US, a US-facing address through SaveOffice, our US partner (Auteur doesn't operate the US service directly), gives you a real point of contact for exactly those onboarding and verification steps, kept separate from the tax question. See how the US address option works and get that layer settled before you turn a channel on.
FAQ
Do I need to collect sales tax if I sell my SaaS through the App Store? In most cases, no — for App Store and Google Play sales, Apple and Google typically act as the merchant of record and calculate, collect, and remit the applicable sales tax or VAT based on the buyer's location. What's still yours is the income tax on the payouts you receive, and in some situations a registration or $0 filing once your activity crosses a state's threshold. Platform tax handling varies by region and product and changes, so confirm the current terms on the developer side and with a tax professional.
Is my own Stripe checkout different from selling on a marketplace, tax-wise? Yes — this is the core difference. On a marketplace or app store, the platform is usually the seller (or merchant) of record and handles the sales tax on the sale it facilitates. On your own Stripe checkout, you are the seller of record, so registration, collection, and remittance are yours once you cross a state's economic-nexus threshold — unless you route the checkout through a merchant-of-record service that takes that job on for a fee.
I'm not in the US — do US marketing rules apply to me? Some do, and being based abroad generally isn't an exemption. Selling into the US can create US sales-tax obligations based on your volume into each state rather than your location, and rules like CAN-SPAM generally apply to commercial email you send to US recipients no matter where you're writing from. The rule of thumb: when you market and sell into the US, US rules tend to travel with the sale — confirm the specifics for your situation with a professional.
Bottom line
The solo-founder SaaS marketing playbook is right about the marketing. Pick two or three channels, commit for a year, ignore the noise. But every channel on that shortlist is also answering a question the guides don't print: when the money moves, who is the seller of record, and who owes the tax? App stores and marketplaces answer it for you. Your own checkout answers it as you. The difference decides whether "get paid" is a settled box or the thing that stalls your launch.
So make the channel choice with that column in view. Then settle the setup layer underneath it — a real entity and a US-facing address through SaveOffice that your payment, app-store, and bank onboarding can actually verify — before your first customer clicks subscribe.
