DEAD SLOW · CAUTIOUS
6.4 ShipScore / 10
Strongest: time/scale of productized SaaS; weakest: zero verified demand evidence.
Condition: Two embedded-payroll platforms or accounting firms must pre-pay for reconciliation before you build integrations.
Part I — The Verdict what the instruments read
01 — The ShipScore breakdown
Control
6
Owns SaaS but needs API access into each payroll platform.
Entry barriers
6
No tracked leader; multi-state tax logic is a real barrier.
Need
6
Zero corpus proof; only OnlyDividends at $0k MRR tracked.
Time-freedom
7
Productized reporting, though early integrations demand hands-on engineering.
Scale
7
US multi-state payroll is huge; capped outside US jurisdictions.
What the five commandments measure
C — Control
Do you own the customer, or does a gatekeeper stand between you and revenue?
E — Entry
How hard is this to copy once it works? A rival's existence isn't the question — the durability of their advantage is.
N — Need
Is demand proven with money rather than vibes?
T — Time
Can income detach from your hours, or did you buy yourself a job?
S — Scale
How far does it reach without linear cost?
Scored on the evidence below, against CENTS as we've adapted it plus a Buffett-style moat reading of every rival — the same referee for every idea, including the ones we generate ourselves. The verdict follows the arithmetic: we never relabel a score to make it read better, and the weakest commandment is always named. The exact rubric stays in-house so the scale can't be written for.
02 — The pace test — $1M/yr
At $800/mo (assumed category price), you need 105 subscribers for a $1M/yr pace.
Nearest tracked rivals on that curve:
OnlyDividends
$0k 0%
Part II — The Evidence the receipts, good and bad
03 — Rival scan — corpus tracks 1 similar, 1 stalled under $2k MRR
Numeral — $100M Series C in sales-tax compliance; adjacent capital could expand into payroll tax.
Accordance AI — Tax/audit platform with OpenAI tie-in and high engagement; could absorb withholding reconciliation.
Stubline/Polsia — Already launching multi-state payroll reconciliation — direct overlap with your exact wedge.
04 — Demand evidence
Corpus tracks one similar product, OnlyDividends, at verified $0k MRR — no proof of spend here.
Reddit: zero demand signals for these keywords.
X chatter: almost none on tax withholding + reconciliation + multi-state SaaS.
Only adjacent proof is Numeral's $100M Series C — sales tax, not payroll withholding.
05 — Risks
Embedded-payroll vendors (Check, Gusto Embedded) build reconciliation in-house as a table-stakes feature.
Compliance liability: wrong withholding verdict exposes you to customer penalties.
Long enterprise sales cycles with finance/accounting buyers burn runway before first revenue.
Fifty-state tax rule maintenance is a permanent cost center, not a one-time build.
06 — Kill switches — what kills this with one decision
Payroll platform API access (Check, Gusto Embedded, Rippling) — Partner API terms or a native reconciliation feature removes your data source overnight.
IRS/state agency filing rule changes — A withholding regime overhaul invalidates your rule engine until costly rewrite.
No visibility into what accountants currently pay for multi-state audit prep.
Stubline/Polsia traction and revenue are unknown from this scan.
Scores judge the market and business model — not your ability to execute. Verified MRR = independently tracked revenue; reviews/upvotes = platform-reported. Judged 2026-09-27.
08 — The wedge & the next step
Sell the audit-ready report to accounting firms handling many multi-state clients, not to the payroll platforms.
Cheapest next step: Call ten multi-state payroll accountants this week; ask what they pay today to catch withholding errors.
