PaydayRails — Payday Super copilot for AU micro-employers

1. One-liner

Payday Super copilot for Australian tradies, cafés, and clinics with 1–9 staff replacing the SBSCH.

2. Trend signal — why now?

The Australian government just shoved 248,000+ micro-employers off a cliff and didn’t build them a parachute.

• 1 July 2026: Payday Super legislation kicks in. Every employer — sole-trader-with-one-staffer included, no small-business exemption — must pay Super Guarantee within 7 business days of every payday, not quarterly. (ATO)
• Same day: the ATO’s free Small Business Superannuation Clearing House (SBSCH) is permanently switched off at 11:59pm 30 June 2026. New users have already been blocked since 1 October 2025. (ATO)
• ABS June 2025 data: 994,178 employing businesses in Australia, of which ~25% (≈248,500) have 1–4 staff. Most use SBSCH today because it’s free. (ASBFEO)
• The 12-month soft-landing PCG 2026/1 ends 30 June 2027 — after that, full SG charge + nominal interest + admin fee on every late payment. (ATO)
• A new statutory concept — Qualifying Earnings (QE) — replaces OTE. Includes commissions, salary-sacrifice amounts, and certain contractor payments. Most micro-employers cannot tell you which contractors count. (Reckon, Grant Thornton)
• New 3-business-day fund return window means bounces must be detected and re-lodged inside the same 7-day clock, or the employer is in breach. (Microkeeper)
• Search signal: “SBSCH closure” content was non-existent 18 months ago. As of May 2026 every Big-4 firm, MYOB, Xero, Reckon, AustralianSuper and dozens of accountants have published panic-mode 2026 guides. (Xero, PayCat)

This is a hard-deadline regulatory event affecting a quarter-million small businesses with no exemption and no government safety net.

3. The opportunity

The incumbents are mis-pricing this market.

• Xero / MYOB / Reckon / Employment Hero all bundle Payday Super into full payroll suites starting around A$30–55/mo. They’d rather upsell a tradie with one apprentice into a $35/mo Xero Starter plan than ship a stripped-down $9 super-only product that cannibalises themselves.
• Free fund clearing houses (AustralianSuper QuickSuper, Industry Super, etc.) are technically free but anchor you to one fund’s portal, ugly UX, no contractor-classification, no STP-vs-SuperStream-vs-bank reconciliation, no AI.
• Payroller, Microkeeper, FREEPAY have free or near-free tiers but they’re full payroll mental models — STP, leave, awards, payslips. A sparky with one apprentice doesn’t want that. He wants “did super land safely on Friday — yes/no.”

The wedge: a payments-and-compliance-only app — no payroll bloat — that makes the Payday Super run literally one screen. Connect bank → confirm pay run (or paste from Xero/MYOB/CSV) → AI flags contractor risk → push via a partner clearing house → green tick on payday +7. Priced for the A$9/mo wallet.

Not “another payroll product.” A focused appliance that solves one regulatory event well.

4. Target market

• Primary customer: Australian micro-employers with 1–9 staff who don’t run a full payroll suite today: sole-trader tradies (electricians, plumbers, builders, landscapers) with an apprentice, café/restaurant owner-operators with 3–8 casuals, allied-health solo practitioners with one receptionist, single-clinic GPs, single-site lawyers/accountants with admin staff. ABN-registered, turnover typically A$200K–A$2M.
• Why they buy: “SBSCH is closing and I don’t want to pay $35/mo for Xero just to send super.” Plus: “I have one contractor who maybe is and maybe isn’t owed super under the new rules — just tell me.” Plus: “If a contribution bounces, I want to know before the 7-day clock kills me.”
• Rough TAM: ~248,500 employing businesses with 1–4 staff (ABS June 2025), plus another tranche of ~89,000 with 5–19 staff (9% of 994K) for whom a focused product still beats Xero+. Realistic addressable wedge: 50K–80K bookings if priced right. At A$9/mo that’s A$5–8M ARR.
• Why now for them: The 30 June 2026 SBSCH switch-off forces every one of them to do something different by July. Most will procrastinate until late June and hit Google in panic mode.

5. Product sketch (MVP)

• One-tap pay run import — paste from Xero / MYOB Solo / Excel / a screenshot of your bank statement. Photo-OCR for shoebox operators.
• Qualifying Earnings calculator — for each employee + contractor, computes correct QE under the new rules. Shows the breakdown line-by-line so you can challenge it.
• Contractor super-liability AI — paste an ABN or describe the relationship in natural English; flags whether the contractor is “labour-only / treat as employee for super.” Shows the test it applied.
• One-click SuperStream submission — pushes the contribution batch via partner gateway (Wrkr / Beam / fund-direct). Same SuperStream Alliance-compliant message every payroll suite uses.
• 7-day clock dashboard — every contribution sits in “Sent → Accepted → Allocated → Done” with a countdown. Bounces light up red with a one-click re-lodge.
• STP ↔ SuperStream ↔ bank reconciliation — three numbers must agree per pay cycle. We compute the diff and tell you what to fix.
• Accountant view — your bookkeeper logs in, sees every client’s payday status in one grid. No more chasing.
• End-of-quarter SG audit pack — auto-bundle for your accountant, ATO-ready.

6. AI angle — what’s load-bearing

Two genuine AI jobs, both load-bearing:

1. Contractor classification. The “is this contractor owed super under Payday Super?” question requires reading the actual ATO multi-factor employee/contractor test against the relationship as the user describes it. Without an LLM doing this in plain English from the user’s words, you’ve shipped a static FAQ. Most accountants currently bill A$200–$400 for this judgment per contractor. We collapse it to a chat answer with citations.
2. Pay-run extraction. Photo of a bank statement, paste of an MYOB Solo screenshot, screenshot of a Xero pay run — the cheapest path for a tradie is “send what you’ve got.” Vision LLM extracts gross/OTE/QE/super per line into the SuperStream payload. Without this, onboarding is a 30-minute CSV-mapping exercise and we lose them.

Strip the AI out and you’re left with a clearing-house front-end. Strip the wedge product instead and you’re left with no margin. The AI does the work that previously required an accountant on a billable hour.

7. Localization angle

This is the localization. SuperStream + ATO + AUSTRAC + the SuperStream Alliance + the Payday Super statutory concept of Qualifying Earnings + Australia’s award/casual labour mix is an entirely Australia-specific stack. A US/UK/global product cannot service this. Vice versa: this product cannot leave Australia (which is fine — A$5M ARR inside a single regulatory regime is the entire pitch).

• Pricing in AUD. Stripe AU + PayTo as billing rails.
• Plain-English “no-jargon” copy in the UI, because the audience is tradies not finance leads.
• Targeted by state (NSW, VIC, QLD have biggest tradie populations) for ad spend.

8. Business model — path to $1M–$5M ARR

• Pricing: A$9/mo flat for up to 5 employees+contractors, A$19/mo for 6–15, A$39/mo for 16–30. Annual prepay 2 months free. No per-transaction fee — gateway costs absorbed.
• ACV: ~A$140 (mix-weighted across the three tiers).
• $1M ARR (USD ≈ A$1.5M): ~10,700 paying customers. From a TAM of ~250K micro-employers facing the deadline, that’s 4.3% capture. Realistic for a 12-month SBSCH-migration window where customers are forced to choose something.
• $5M ARR (USD ≈ A$7.5M): ~54K customers, or ~22% of the 1–4 staff segment plus penetration into 5–19 staff. Stretches the wedge — by month 18 we either expand into accountant-channel resale or add adjacent compliance modules (BAS reminder, Director ID, etc.).
• Expansion path: (a) accountant/bookkeeper firm tier — A$99/mo for up to 20 client books, A$249/mo unlimited, white-label optional. (b) Director ID + ASIC company-renewal compliance modules. (c) STP-only filing add-on for clients who outgrow super-only.

9. Go-to-market wedge — first 100 customers

This is the bullseye and it’s surprisingly tight.

• Day 0–14: Accountant/bookkeeper LinkedIn outbound. Scrape the 4,800 IPA + 1,300 ICB Australia members list. DM the 800 micro-firm bookkeepers (sole proprietor or 2-4 staff) the same Loom: “Your tradie clients are about to switch payroll because of SBSCH. We give you a free pro-account if you let us be the SBSCH-replacement recommendation. We do super only. We won’t compete on bookkeeping.” Expect 8–12% reply, 25 first conversations, 8 pilot firms × 5 client referrals = 40 customers.
• Day 14–45: Niche subreddit + Whirlpool. /r/AusFinance (700K), /r/smallbusinessaustralia (50K), Whirlpool Small Business forum (the actual home of micro-employer Australia). Answer every “SBSCH closing what do I do” thread with a substantive guide and a soft mention. Hit 30 customers.
• Day 30–60: Tradie Facebook groups. “Sparky Australia,” “Builders & Tradies AU,” “Small Business Tradies Australia” — combined ~150K members. Run a free 5-min “Am I Payday Super ready?” diagnostic that drops them into the funnel. 30 customers.
• Day 0–90: Google Ads on hand-raisers. “SBSCH alternative”, “payday super for one employee”, “cheapest super clearing house Australia.” Long-tail, low-volume, very high intent. CPCs in the A$3–6 range. A$2K spend → ~15 customers at 4% conversion.
• Always-on: SEO content engine. Two posts a week on the long-tail keywords above. Compound from month 3 onward.

If we can’t get 100 paying customers in 90 days from this in a market of 248K forced movers, the idea is wrong and we kill.

10. Build complexity — justification

Medium. SuperStream message generation (SAFF / contribution XML / receipt parsing) is well-documented and a partner gateway like Wrkr or Beam handles the actual fund-routing leg under contract — not greenfield work. STP Phase 2 reporting is similar — the spec is open. The two AI features (vision extraction of pay runs + contractor classification chat) are off-the-shelf with prompts. The legal/ESA setup is the slowest path: ~4–8 weeks to get a partner-gateway contract signed and confirm we don’t need our own AFSL by routing payments end-to-end through a licensed partner. Realistic v1 in 14–18 weeks with two builders. Not a 6-week toy. Not a research project.

11. Gating checklist

Gate	Pass?	Note
Legal in target market	✅	Operate as software in front of a licensed partner gateway. Confirm AFSL not required by not taking custody of funds.
Ethical — no harm / dark patterns	✅	Solving a forced regulatory move. Cheaper than incumbents.
Market exists (evidence above)	✅	~248K forced movers, hard 30 Jun 2026 deadline.
1–5 person team can build this	✅	2 builders, 14–18 weeks.
Launchable with <$50K / ₹40L	✅	A$30K covers gateway partner contract, AU entity, AUSTRAC light-touch advice, 6 months of Stripe + LLM API.

12. Feasibility score

Axis	Weight	Score	Notes
Problem intensity	20	17/20	Hair-on-fire for the affected wallet. ATO penalties + SG charge + interest = real money. SBSCH closing is a forced event, not a “nice to have.”
Demand evidence	15	13/15	248K affected. Multiple Big-4 panic guides. ATO actively pushing migration. Only thing missing: I haven’t seen a viral Reddit thread of SMEs panicking yet — that’s a May/June 2026 thing.
Build feasibility	15	11/15	SuperStream + STP specs mature, AI tasks are off-the-shelf, but the gateway-partner contract is a non-trivial business-development lift before line one of code lands.
Distribution clarity	15	11/15	Accountant outbound + niche forums + Google long-tail intent are all named, addressable channels. Conversion math reasonable but unproven on the bookkeeper-channel leg.
Revenue mechanics	15	11/15	Pricing benchmarked against MYOB Solo (A$10/mo), Payroller (~A$16/mo min), Easy Business App (A$9.95). Math to A$1.5M ARR is realistic. A$7.5M ARR requires expansion modules.
Time to first revenue	10	8/10	Pre-launch waitlist with deposit can land first revenue at MVP launch (~week 16). Hard deadline pulls forward demand.
Defensibility	10	7/10	Soft moats: bookkeeper-channel relationships, AI contractor-classification corpus that compounds, brand as “the SBSCH replacement.” Copyable in ~6–9 months by a Xero-style player but they don’t want to.
Total	100	78/100

13. Qualitative modifiers

Founder-fit tags

technical-heavy · domain-expertise-required

The founder needs to either be an Australian who’s run payroll, or pair with a registered BAS agent / bookkeeper as advisor from day 1. Without domain trust, the accountant channel doesn’t open.

Key assumptions to validate (3–5)

1. Assumption: Micro-employers will pay A$9/mo for a super-only product when free fund clearing houses exist. How to test: Pre-launch waitlist with a A$1 deposit, target 200 deposits in 30 days from a A$1K Google Ads + Reddit content spend. Read intent from conversion rate.
2. Assumption: A partner-gateway model (Wrkr / Beam / equivalent) lets us avoid AFSL/AUSTRAC custody licensing. How to test: Two paid 1-hour calls with an Australian fintech compliance lawyer + one term-sheet conversation with Wrkr partner team. Decision in 2 weeks.
3. Assumption: The bookkeeper/accountant channel will refer 5+ clients per pilot firm. How to test: Sign 3 unpaid pilot bookkeepers on a handshake before code is written; if none of them can name 5 clients who’d pilot, the channel is weaker than assumed.
4. Assumption: Vision-extraction of pay runs from photos / pasted screenshots works reliably enough that onboarding is sub-5-minute. How to test: Build the extraction step alone as a Streamlit demo on real anonymised pay slips, target ≥90% line-item accuracy on 50 samples.
5. Assumption: Customers will trust a 6-month-old startup with their super payment workflow. How to test: Ship via a known accountant brand co-sign / press release in Accountants Daily or Accounting Times, measure conversion lift vs cold ad traffic.

Risk flags

1. Regulatory risk: ATO could change implementation rules or extend the SBSCH transition. Mitigation: the pain remains even if the deadline slips — Payday Super itself doesn’t go away.
2. Platform dependency: We rely on a partner gateway (Wrkr / Beam). Their pricing or willingness to onboard a thin SaaS in front of them could become a chokepoint. Mitigation: have a second gateway warm.
3. Incumbent retaliation: Xero or MYOB launches a free “super-only” tier to defend territory. Probable in months 6–12. Mitigation: dig the bookkeeper-channel moat early; price-only is a weak attack against entrenched workflow.
4. Capital intensity at scale: Per-transaction gateway fees could compress margin if customers run weekly payroll. Need to model this carefully and consider tiering.
5. Trust risk at zero history: Hardest objection in the first 6 months. Surface ATO partner-gateway lineage prominently.

14. Structured verdict

Score:                  78/100
Verdict:                GO
Confidence:             Medium
Best-fit builder:       Australia-based technical founder with payroll/bookkeeping advisor or co-founder; or solo technical operator partnered with a registered BAS agent
Time to revenue:        14–18 weeks to MVP, first paid customers via pre-launch deposit list
Capital to launch:      A$30–40K (partner-gateway contract, AU entity, fintech compliance counsel, 6 months of LLM + Stripe + hosting)
Top 3 assumptions to validate first:
  1. Partner-gateway model avoids AFSL/AUSTRAC custody requirements (compliance lawyer call + Wrkr term sheet, 2 weeks)
  2. Bookkeeper channel will refer 5+ clients per firm (3 unpaid pilot bookkeepers signed pre-build, 3 weeks)
  3. A$9/mo pricing converts at ≥3% from intent traffic (200 deposits from A$1K paid spend in 30 days)
Kill criteria:
  - Abandon if Wrkr/Beam/equivalent partner won't onboard a thin SaaS in front of them at a workable per-payment cost (<A$0.50/contribution at <500 customer scale)
  - Abandon if pre-launch waitlist deposits convert below 1.5% from cold paid traffic
  - Abandon if Xero or MYOB ship a free "super-only" tier before we hit 1,000 paying customers — the wedge is gone
  - Abandon if the AFSL/AUSTRAC question can't be cleanly resolved with the partner-gateway model — the capital math breaks

15. Next step — 1-week validation sprint

• Day 1: Book two fintech-compliance lawyer calls (Sophie Grace, Holding Redlich-style) on the AFSL question. Cost ~A$1,200 total.
• Day 2: Email Wrkr and Beam partner teams with a one-page proposed integration; ask for indicative per-payment pricing at 100 / 1,000 / 10,000 customer scale.
• Day 3: Build a 1-page landing page (paydayrails.com.au) — value prop + A$1 deposit waitlist via Stripe AU. Two pricing tiers shown.
• Day 4: Spin A$500 Google Ads campaign on “SBSCH alternative”, “payday super clearing house small business”, “cheapest super clearing house Australia.” Plus 6 substantive Reddit/Whirlpool comments on existing SBSCH-closure threads.
• Day 5: DM 50 micro-bookkeepers via LinkedIn with a Loom demo. Target 5 reply-and-book-call conversions.
• Day 6: Read the data. Lawyer answer + gateway pricing + waitlist conversion + bookkeeper interest.
• Day 7 — Decide: Go if (a) lawyer says partner-model works without AFSL, (b) Wrkr/Beam quote <A$0.50/contribution at scale, AND (c) ≥30 deposits + ≥3 booked bookkeeper calls. No-go if any one of those misses.

Falsifiable. Cheap. One week.
