Solution / Software platforms
Embed accounting without becoming a ledger company.
Send canonical business events once. Invarent applies accounting policy, controls financial effects, returns state through APIs and webhooks, and keeps provider-specific internals out of your product model.
Embedded accounting infrastructure lets a software platform offer controlled books, workflows, reports, and financial state through an API while a specialized financial kernel owns double-entry integrity, permissions, evidence, reconciliation, and change control.
Platform integration record
Control evidence belongs beside the outcome.
- Contract
- Versioned OpenAPI, canonical events, stable external IDs, exact decimals, and typed SDKs
- Control boundary
- The browser and customer integration cannot write financial tables or bypass posting policy
- Delivery
- OAuth/API keys, scopes, idempotency, webhooks, retries, dead letters, replay, and usage evidence
- Portability
- Provider abstractions and tenant export prevent the operating product from inheriting one vendor's object model
What changes
Move the team from reconstruction to controlled review.
Integrate the business event once
Use a canonical event contract for invoices, bills, payments, time, jobs, contracts, bank activity, and other operating records.
Keep accounting risk behind a hard boundary
Financial effects travel through authenticated API policy and atomic database controls rather than direct journal or browser writes.
Return evidence with state
Use status, exceptions, approvals, reports, webhooks, hashes, and audit context to build product experiences users can trust.
Operating sequence
One financial chain, explicit at every handoff.
- 01
Provision an isolated tenant
Create the entity, books, periods, chart template, sandbox generation, scoped credentials, and integration identity.
- 02
Send canonical events
Preserve source identity, external IDs, effective dates, exact amounts, dimensions, and documents without translating into uncontrolled journal lines.
- 03
Consume controlled outcomes
Receive accepted, held, rejected, posted, reconciled, and exception state through stable APIs and signed webhooks.
- 04
Embed the right surface
Expose branded operator, approval, report, or developer workflows while the trusted API remains the only financial writer.
Questions buyers ask
Clear boundaries before implementation.
Do we need to understand debits and credits to integrate?
Most operating integrations should send the business event and its source context. Invarent maps that event through approved accounting policy. Explicit journal workflows remain available for authorized accounting use cases.
Can our frontend write directly to Supabase or PostgreSQL?
No. The browser never writes financial schemas directly. Every financial command passes through the authenticated accounting API and transaction controls; RLS remains a secondary isolation layer.
How are duplicate events prevented?
Source identity, external IDs, idempotency keys, payload hashes, and financial effects are committed under one atomic contract so retries do not create duplicate accounting impact.
Can we use our own user interface?
Yes. Platforms can build against the public API and SDKs, use hosted portal surfaces, or embed approved components. The financial control boundary remains the same in every presentation.
A controlled starting point
Ship the accounting experience, not the accounting liability.
Use one canonical event contract, keep provider and ledger internals behind the control plane, and return evidence-rich financial state to your product.
