Everything you'd ask in a
second call — answered here first.

Those tools focus on sales tax collection at point-of-sale. Moundi covers what comes after — registrations, returns, plus everything that isn't sales tax: annual reports, franchise tax, payroll filings, federal forms, international corporate tax. We integrate with them rather than replace them.

Finance and ops leaders at venture-backed SaaS, marketplaces, and global services firms operating across multiple US states and (increasingly) international entities. The sweet spot is 5–50 entities with recurring multi-jurisdiction obligations.

Moundi today is built around US-headquartered companies with international footprints. If you're based outside the US, get in touch — we're talking to a small set of UK and Canadian companies in design partnership.

Most teams are live in 3–5 business days. You map your entity structure (about 15 minutes), connect your ledger and payment processors, and the obligation calendar auto-populates. Historical exposure scans run in the background and surface results within 24 hours.

We orchestrate filings through regulated partners (Marosa for EU VAT, Avalara Advisory for US sales tax, TMF Group for entity setup). Moundi is the workspace and the audit trail; the partners are licensed to file.

For state filings, yes. For federal income tax (1065, 1120, 1120-S), we organize the calendar and supporting data but currently hand off to your CPA. Direct federal filing is on the roadmap for 2027.

Yes. You can invite your CPA as a collaborator with read or review access. They see the same calendar, evidence, and draft returns you do — no more month-end PDF email threads.

The obligation flips state, an incident is opened in the maintenance log, and the responsible partner is notified through the same workflow they used to file. Penalty exposure, partner correspondence, and resolution steps are all captured in the evidence ledger.

Connect your billing and ledger systems and Moundi backtests every transaction against current nexus thresholds in each state and country. You see exactly where you've crossed economic nexus, when, and what the remediation cost would be.

A segregated balance per jurisdiction. As taxable revenue lands, the wallet auto-accrues what's owed so funds are quarantined before remittance day. You can fund it on a schedule or top up manually — the ledger always reconciles to what's been collected vs. owed.

Yes — multi-entity is core, not an add-on. Each entity has its own obligation calendar, registrations, ledger connections, and partner assignments, all rolled up into a single group view for finance leadership.

Workspace roles include Owner, Admin, Operator, and Read-only. Entity-scoped roles let you give a regional controller access to just one subsidiary. CPAs and partners get review-only access by default.

Out of the box: Stripe, Shopify, NetSuite, QuickBooks Online, Xero, Rippling, Gusto, Mercury, Brex, and Plaid for banking. The integrations layer is API-first, so custom sources connect through our ingest endpoint.

On Supabase (Postgres) in US-East with row-level security per workspace. Documents and evidence artifacts sit in object storage with signed-URL access. Daily encrypted backups; point-in-time recovery available on Scale and Enterprise plans.

Yes. The reports module produces CSV and PDF exports per entity, per jurisdiction, per period. A full workspace export (entities, filings, ledger, evidence) ships as a ZIP from the Settings page on demand.

SOC 2 Type II in progress (target Q4 2026). Bank-grade encryption at rest and in transit. Multi-tenancy enforced at the Postgres row level. SSO/SAML on Enterprise. Audit log for every action — including reads on sensitive evidence.

Every filing, registration, threshold breach, partner exchange, and user action writes an immutable record with timestamp, actor, payload hash, and source document. When auditors ask 'who did what, when, and on what basis,' you hand over a signed export instead of reconstructing the past.

Flat monthly plans by entity count and corridor coverage (see the pricing page). Filing fees charged by tax authorities are passed through at cost. No per-transaction take-rate, no surprise overages — the bill matches your structure.

Export your entire workspace — entities, filings, evidence ledger — as a ZIP. Your data is yours. We retain a hashed audit fingerprint for 12 months in case partner authorities require corroboration, then it's purged.
