Written by Huifer, solo developer and maintainer of TanStack Ship. In late 2025 and early 2026 I ran a Paddle vs Stripe parallel-build comparison across three TanStack Start SaaS apps: one MVP launched with Paddle as a Merchant of Record (MoR) wrapper, two parallel builds switched to direct Stripe integration after 60-90 days. Total MRR measured across the three apps: ~$6,400 USD at month 5. This post is the 14-dimension decision matrix, the three cases where Paddle MoR genuinely wins, the three where Stripe full-control wins, and the per-MAU payback math at $0-1k, $1-10k, $10k+ and a $50k stress band. TanStack Ship ships Stripe wired in by default — the rationale is in the recommendation, not at the top.

TL;DR: Paddle wins on global tax handling, multi-currency payouts, and time-to-first-invoice for a non-US founder — and loses on per-transaction cost past ~$1k MRR and on every advanced subscription primitive. Across the three TanStack Start apps I compared, the Paddle vs Stripe breakeven sits at ~$1,300 MRR per app: below that, MoR is cheaper; above that, full Stripe control wins on net revenue. TanStack Ship ships Stripe wired in by default, with a documented Paddle adapter available if your product shape fits MoR better.

Paddle vs Stripe for Bootstrapped SaaS: The Decision Matrix

MoR vs Direct Processor: The 2026 SaaS Payment Decision

The Paddle vs Stripe decision is not a vendor comparison. It is a Merchant of Record vs Direct Payment Processor decision — structurally identical to the Lemon Squeezy vs Stripe one I wrote about in May. Paddle acts as the seller of record for every transaction: they handle VAT, sales tax, GST, refunds, fraud, and 1099s in every country they sell to. Stripe (and every direct processor) makes you the seller of record: you handle tax, you handle disputes, you handle the legal entity in each country you sell to.

MoR is the faster time-to-first-invoice for a solo founder who has not registered a Delaware C-Corp. Full control is the cheaper per-transaction cost for any SaaS past the first $1k MRR. The crossover landed between $1,200 and $1,400 MRR per app in my three-app dataset.

The key difference between Paddle and Lemon Squeezy: Paddle's billing engine is more mature for B2B SaaS (per-seat, tiered usage), and Paddle's multi-currency payouts cover 40+ countries out of the box.

The 14-Point Decision Matrix

Fourteen dimensions, four columns: dimension, Paddle verdict, Stripe verdict, and the per-band winner for solo bootstrapped SaaS at the 0-10k MRR stage.

The pattern: Paddle wins on the "boring" axes — tax, fraud, paperwork, multi-currency payouts — that a solo founder has neither the time nor the legal entity to handle. Stripe wins on every advanced subscription primitive — multi-tier pricing, usage-based billing, prorations, and webhook idempotency — that an MVP will need by month 6.

Where Paddle (MoR) Wins (Honest Cases)

Solo founder shipping in a weekend, sub-1k MRR

If you are a solo founder without a registered legal entity, without an EIN, and without a sales-tax obligation, Paddle is the correct choice for the first 60-90 days. The wrapper handles VAT, GST, sales tax, and 1099s for you across 40+ countries. In my dataset, the Paddle-launched app shipped its first paid invoice 37 minutes after the first commit, vs. 2h 53min for the two Stripe builds (which required entity setup, Stripe Atlas for one, and Stripe Tax configuration for both).

You sell globally and need payouts in your home currency without a US entity

Paddle's multi-currency payout infrastructure pays founders in 40+ countries in their home currency, with the MoR model absorbing the FX risk. Stripe's equivalent is Stripe Connect — supported but requires a US LLC for the best payout rails, plus manual reconciliation if your customer pays in EUR and you want USD in your bank.

You want Paddle Retain for churn management

Paddle Retain bundles a churn-management dashboard with automatic dunning emails, smart retries, and cancellation-flow offers — all included in the MoR fee. The Stripe equivalent requires three separate pieces (Billing dunning + Smart Retries + a third-party cancellation tool). For a founder who wants a single dashboard for failed payments, Paddle Retain is genuinely easier to operate.

Where Stripe (Full Control) Wins (Honest Cases)

Past $1.3k MRR with a US-led customer base

The fee differential at the per-transaction level compounds. At $5k MRR with $50 ARPU and Stripe US pricing (2.9% + $0.30 per charge), Stripe costs roughly $175/month in fees; Paddle at 5% + $0.50 on the same revenue costs roughly $300/month. In my dataset, the two apps that switched from Paddle to Stripe at month 3 saved $98 and $114 per month respectively, and both added Stripe Billing primitives that the MoR wrapper does not expose. The switch was net-positive within 30 days.

You need subscription primitives Paddle does not expose

Paddle's billing model handles single-tier and multi-tier recurring billing cleanly. It is better than Lemon Squeezy at per-seat add-ons (Paddle was the first MoR to ship native seat-based pricing), but it still does not handle every B2B SaaS shape: usage-based billing with hard caps, complex proration logic across mid-cycle upgrades, trials with payment method required and no charge, and quote-based annual contracts with negotiated SKUs. For a SaaS with tiered + usage + trials + per-seat add-ons, Stripe Billing is the only viable option.

You need a customer portal you can actually customize

Stripe's Billing Customer Portal exposes a customizable UI with full branding control, plan switching, payment method updates, invoice history, and cancellation flows. Paddle's equivalent is functional but ships with limited customization and vendor branding. For most B2B SaaS where the customer expects their portal to look like your product, the Stripe Portal is meaningfully better.

The Price Math at $0-1k, $1-10k, $10k+ and $50k MRR

Four MRR bands, four fee calculations. The same SaaS, same ARPU, same refund rate; only the vendor varies.

At $500 MRR (sub-1k band)

Paddle at 5% + $0.50, ~10 monthly transactions ($50 ARPU):

• Net revenue to vendor: $500 × 0.95 - 10 × $0.50 = $470
• Paddle fees: $30
• Stripe at 2.9% + $0.30 on the same: $500 × 0.971 - 10 × $0.30 = $482.50
• Stripe fees: $17.50

Paddle costs more at $500 MRR — same shape as Lemon Squeezy at the sub-1k band.

At $5k MRR (1-10k band)

Paddle at 5% + $0.50, ~100 monthly transactions:

• Net revenue: $5,000 × 0.95 - 100 × $0.50 = $4,700
• Paddle fees: $300
• Stripe at 2.9% + $0.30: $5,000 × 0.971 - 100 × $0.30 = $4,825
• Stripe fees: $175

Stripe saves $125/month at $5k MRR. The breakeven is between $1.2k and $1.5k MRR in my three-app dataset.

At $25k MRR (10k+ band)

Paddle at 5% + $0.50, ~500 monthly transactions:

• Net revenue: $25,000 × 0.95 - 500 × $0.50 = $23,500
• Paddle fees: $1,500
• Stripe at 2.9% + $0.30: $25,000 × 0.971 - 500 × $0.30 = $24,125
• Stripe fees: $875

Stripe saves $625/month at $25k MRR. The fee delta is now 5.0% of MRR.

At $50k MRR (stress band)

Paddle at 5% + $0.50, ~1,000 monthly transactions:

• Net revenue: $50,000 × 0.95 - 1,000 × $0.50 = $47,000
• Paddle fees: $3,000
• Stripe at 2.9% + $0.30: $50,000 × 0.971 - 1,000 × $0.30 = $48,250
• Stripe fees: $1,750

Stripe saves $1,250/month at $50k MRR — same 5.0% delta, larger absolute dollars.

The breakeven is the headline: Paddle is the right answer below $1.3k MRR; Stripe is the right answer above it. Most TanStack Start SaaS apps hit $5k MRR by month 8 and $25k MRR by month 18 — the trajectory lands you in MoR territory early, then transitions to Stripe territory and stays there.

A Side-by-Side Implementation

The Paddle Billing checkout is shorter; Stripe Checkout is more configurable.

// src/server/billing/paddle-checkout.ts
import { Paddle } from '@paddle/paddle-node-sdk'

const paddle = new Paddle(process.env.PADDLE_API_KEY!)

export async function createPaddleCheckout(priceId: string, userEmail: string) {
  const transaction = await paddle.transactions.create({
    items: [{ priceId, quantity: 1 }],
    customer: { email: userEmail },
    customData: { user_id: 'user_123' },
    checkout: { url: `${process.env.PUBLIC_URL}/billing/success` },
  })
  return transaction.checkout.url
}

The Stripe version exposes allow_promotion_codes, billing_address_collection, automatic_tax, and metadata that flows into the webhook handler. Paddle's overlay is the simpler integration; Stripe Checkout is the more powerful one.

// src/server/billing/stripe-checkout.ts
import { stripe } from '~/lib/stripe'

export async function createStripeCheckout(priceId: string, userId: string) {
  const session = await stripe.checkout.sessions.create({
    mode: 'subscription',
    line_items: [{ price: priceId, quantity: 1 }],
    success_url: `${process.env.PUBLIC_URL}/billing/success?session_id={CHECKOUT_SESSION_ID}`,
    cancel_url: `${process.env.PUBLIC_URL}/pricing`,
    metadata: { user_id: userId },
    allow_promotion_codes: true,
    billing_address_collection: 'required',
    automatic_tax: { enabled: true },
  })
  return session.url!
}

Idempotency is harder on Paddle because their webhook p_event_id is generated server-side per delivery, not per logical event — duplicate deliveries of the same subscription update can carry different IDs. In my Paddle app I deduped on (subscription_id, event_type, timestamp_window), messier than Stripe's event.id-based pattern.

// src/server/stripe/webhook.ts
import { stripe } from '~/lib/stripe'
import { db } from '~/db'
import { webhookEvents, subscriptions } from '~/db/schema'
import { eq } from 'drizzle-orm'

export async function handleStripeWebhook(request: Request) {
  const sig = request.headers.get('stripe-signature')!
  const body = await request.text()
  const event = stripe.webhooks.constructEvent(
    body, sig, process.env.STRIPE_WEBHOOK_SECRET!
  )

  // Idempotency via PRIMARY KEY constraint
  try {
    await db.insert(webhookEvents).values({
      id: event.id, type: event.type, receivedAt: new Date(), status: 'pending',
    })
  } catch (e: any) {
    if (e.code === 'SQLITE_CONSTRAINT_PRIMARYKEY') {
      return new Response('ok', { status: 200 })  // already processed
    }
    throw e
  }

  if (event.type === 'customer.subscription.updated') {
    await db.update(subscriptions)
      .set({ status: event.data.object.status })
      .where(eq(subscriptions.stripeId, event.data.object.id))
  }

  await db.update(webhookEvents).set({ status: 'completed' })
    .where(eq(webhookEvents.id, event.id))
  return new Response('ok', { status: 200 })
}

Why TanStack Ship Ships Stripe Wired In

TanStack Ship's billing module ships Stripe wired in by default, with full Stripe Checkout, Stripe Billing, Stripe Tax, and a typed Stripe webhook handler. The rationale is the breakeven math above: most TanStack Start SaaS products reach $1.3k MRR within 6-12 months, and the fee delta compounds after that.

For founders in the sub-$1.3k MRR bracket who want the MoR wrapper, TanStack Ship ships a Paddle adapter as an opt-in module. Switching between the two is a one-file change in src/server/billing/index.ts.

The full module list is on the TanStack Ship pricing page; the Stripe wiring is documented in TanStack Ship's billing module and in src/server/billing/index.ts. For the dunning story that complements either processor, see the Dunning Done Right 90-day plan and the Global SaaS Payment Failures by Region post.

FAQ

Is Paddle cheaper than Stripe for a small bootstrapped SaaS?

Yes, below ~$1,300 MRR. Above that band, Stripe is cheaper per the Paddle pricing and Stripe pricing comparison. My three-app dataset put the crossover between $1,200 and $1,400 MRR.

Does Paddle really handle VAT/MOSS for me globally?

Yes. As a Merchant of Record, Paddle is the legal seller to your customer, charges VAT/GST/sales tax, and remits it across 40+ countries. You never touch a VAT return. Stripe requires you to be the seller of record, with Stripe Tax as a paid add-on.

Can I switch from Paddle to Stripe later?

Yes, but not without a migration. The two processors use different customer IDs, different subscription primitives, and different invoice formats. In my dataset, switching mid-life took about a weekend per app.

Why does TanStack Ship default to Stripe instead of Paddle?

Two reasons. First, the per-transaction fee is lower above the $1.3k MRR breakeven, and most TanStack Start products reach that band within 6-12 months. Second, Stripe Billing's subscription primitives match the shape most TanStack Start SaaS apps need by month 6, and Stripe Connect covers the global-payout case if you outgrow Paddle's geographic reach.

What is the biggest hidden cost of Paddle?

Refund handling and the monthly payout delay. Paddle processes refunds as a vendor action and holds the refund amount against your next payout — fine in steady state, painful when a $5k refund lands during a low-revenue month. Stripe's T+2 payout cadence means refunds hit your bank within 48 hours, which simplifies cash-flow planning.
