One-click Stripe invoice batch export — auto-zips by date range, tags by tax jurisdiction, emails to your accountant on the 1st of every month.

What we ship

**Core features (MVP)**

• One-click Stripe Connect: read-only OAuth in 30 seconds; no card data ever touched, scope `invoice:read` only.
• Date-range picker → ZIP download: pick a period (last month, last quarter, custom), hit Export — get a zip of every PDF in 60 seconds.
• Tax-jurisdiction tagging: each PDF in the zip is renamed `2026-04-12_INV-1042_US-CA_$129.pdf` for accounting-system import; multi-currency split into subfolders.
• Scheduled monthly delivery toggle: a switch "Email this ZIP to my accountant on the 1st of each month"; preset recipient + cc:.
• Multi-account for the bookkeeper segment (Pro+): one dashboard, up to 5 client Stripe accounts, white-label email branding.

**Primary user flow**

1. Solo founder on Stripe googles "stripe bulk invoice download" at month-end, racing the accountant deadline; lands on the page.

2. One-click Stripe Connect (read-only) in 30 seconds, picks "Last month", hits Export; downloads the ZIP within 60 seconds.

3. Aha moment: PDFs are already tagged with jurisdiction + currency, the accountant imports in one command.

4. Toggles "Email on the 1st of every month" — next month happens fully automatically; upgrades to $9/mo Solo.

**What it looks like**

• **Landing page**: hero "Stripe → Accountant. One click. Forever." Simple 3-step diagram: Connect Stripe → Pick range → Email auto-sent. Customer quote "saves 2 hours per month-end". CTA: "Connect Stripe — first export free".
• **Main app screen**: single-page dashboard — top: connected Stripe accounts + Add another. Center: date-range picker + Export button + history of past exports (download / re-send). Bottom: scheduled-delivery card "Next run: May 1, recipient: cpa@example.com" + edit/pause.
• **Output format**: ZIP file with structure `2026-04/USD/2026-04-12_INV-1042_US-CA_$129.pdf` (year-month / currency / date-number-jurisdiction-amount); accompanying email "April 2026 — 47 invoices, $5,302 total, attached".

**MVP build plan (5 days)**

• Day 1: FastAPI + Postgres + Celery (Redis) on Railway, JWT, Stripe Subscriptions ($9/mo), Cloudflare R2 (30-day TTL).
• Day 2: Stripe Connect Standard OAuth (read-only invoice scope), list invoices via Stripe API.
• Day 3: PDF fetch + ZIP builder + tax-jurisdiction tagger (country → `US-CA`, `GB-VAT`, `EU-DE-VAT`).
• Day 4: React + Tailwind dashboard — date-range picker, Export, history; Resend for email delivery + scheduler (Celery beat, 1st of month).
• Day 5: Landing page, Stripe App Store submission assets, DPA template, smoke test, ship.

Source signals

• **SIG-20260425-us-micro-saas-utility-stripe-invoice-batch-download**: "wasting a lot of time downloading Stripe Invoices one-by-one... created a simple, rough-around-the-edges script" — Invoice Powerup proves market
• **SIG-20260425-us-micro-saas-utility-vendor-invoice-ocr-sweet-spot** (adjacent): bookkeeper power-user persona overlaps — same audience that processes vendor invoices also processes own Stripe outputs

Reasoning

The signal explicitly documents the pain ("wasting a lot of time... at month-end... in a rush to meet some accountancy submission deadline") plus a Stripe community of "hundreds of forum complaints" over years. Invoice Powerup proves the market exists and a single-feature SaaS can sustain. The white-space: (1) auto-tagging by tax jurisdiction (critical for EU VAT/MOSS founders), (2) scheduled monthly auto-delivery to accountant, (3) multi-currency split for accounting-system import. Build is the smallest in this batch (5 days) — Stripe Read API + Celery scheduler + ZIP generation + R2 + Resend email. Recurring revenue is structurally perfect: monthly value delivered automatically, near-zero churn while founder uses Stripe. Adjacent expansion to Square/Paddle/Lemon Squeezy/Chargebee = clone-pattern revenue multiplier.

Quick competitive read

• **Invoics.com** (pricing not public) — bulk Stripe + Shopify export, "officially suggested by Stripe support"
• **MassInvoices** (per-batch paid) — Reddit-launched solo indie tool, one-time job model
• **Bulk Invoice Download (Stripe Marketplace App)** ($5-15/mo) — Stripe-native, dashboard-only, no email delivery
• **Quaderno** ($49+/mo) — full tax-compliance engine, includes "combine invoices into PDF" but priced 5x higher
• **Re-cap.com Stripe Invoice Exporter** (free utility) — solo-built for an internal company need
• **Stripe Atlas / Stripe Tax** — Stripe's own tools, no batch-export
• **Paddle / Lemon Squeezy native** — exist for those platforms, don't help Stripe users
• **GitHub python scripts** — useless for bookkeepers (no UI, no scheduler)

Market density: **medium (4-5 thin direct competitors + free utilities)**. None combine our 3-fold wedge: (1) tax-jurisdiction auto-tagging for EU VAT/MOSS, (2) scheduled monthly auto-delivery to accountant, (3) multi-currency split for accounting-system import. competitive_pressure scored 7 (favorable white-space). Plan year-1 expansion to Square / Paddle / Lemon Squeezy / Chargebee — same code, multiple revenue streams.

Initial pricing hypothesis

$9/mo Solo (1 Stripe account, monthly batch) → $19/mo Pro (multi-account, weekly schedule, tax-jurisdiction tagging) → $49/mo Bookkeeper (5 client accounts, white-label email branding). Low-price-high-volume, anchored on Invoice Powerup and developed-tier WTP $10-100/mo solo.

Distribution hypothesis

Three waves:

1. **SEO long-tail** — "stripe bulk invoice download", "stripe batch export accountant" — high buyer-intent keywords

2. **r/stripe, Stripe community forums, Indie Hackers** — text posts with use-case ("I save 2 hours every month-end")

3. **Cold-email to bookkeepers on LinkedIn** — each bookkeeper = 5-15 client accounts
