What happens if a manager does not approve a request within the deadline?

Our workflow engine monitors SLA timers using Redis background workers. If an approval is pending past the configured SLA (e.g. 4 hours), the system automatically escalates notifications to senior management.

Can workflow rules include conditional branching based on financial amounts?

Yes. For example, purchases under $1,000 can be auto-approved, purchases up to $10,000 require Department Manager sign-off, and purchases above $10,000 require CFO authorization.

Is there an audit log of all workflow actions?

Yes. Every state transition records the user ID, timestamp, IP address, previous state, new state, and any approval notes in an append-only PostgreSQL audit log.

Custom Workflow Automation Engines

Specialized Focus

Specialized Overview & Architectural Focus

When business workflows rely on manual email chains and informal verbal approvals, tasks get lost, deadlines are breached, and operational bottlenecks stall revenue. NVIT.SPACE builds custom workflow automation engines that enforce business logic, automate sequential approvals, and maintain complete audit logs.

We design deterministic finite-state machines (FSM) in TypeScript and Node.js that validate business rules at every step (e.g. credit approvals, procurement sign-offs, customer onboarding).

Every workflow state transition triggers automated actions: dispatching WhatsApp notifications to managers, generating PDF approval documents, and escalating stalled tasks automatically when SLA deadlines are breached.

Built for Operations Teams Managing Multi-Stage Approvals:

Financial institutions managing multi-tier credit approval and loan underwriting chains.

Corporate procurement teams handling purchase requisitions and manager sign-offs.

HR and operations departments automating employee onboarding and document verification.

Customer success teams managing service ticket escalation and SLA monitoring.
