Delphi tenancy suite: e-signatures and accounting-ready exports

Contracts and dunning lived in Delphi

The firm tracks leases, index steps and dunning stages in a desktop suite. A new signature provider and tighter bookkeeping expectations required structured transfers.

Replacing the entire stack was neither funded nor acceptable for daily operations.

Signatures yes—but without casework losing its daily tool.

Tenant separation and accounting exports

Several property managers share the installation; exports for the accounting partner had to be reproducible and audit-safe.

Signature workflows must not mix tenants; PDF/A and metadata had to stay separated.

Tax advisors expected reproducible month-end closings without manual Excel intermediate steps.

Target state: signature and export from the contract screen

PDF/A bundles, signature status and monthly posting batches should be controlled from Delphi—with webhook callbacks and without mandatory portal workflows.

Casework should handle signature and export steps in the familiar daily routine.

Audit expects reproducible evidence without media break to the signature platform.

Phased module approval allows gradual introduction of new document types.

Tax advisors expect reproducible month-end closings without Excel intermediate steps.

Tenant separation must remain technically and audit-safely demonstrable.

Casework should see signature status in the shell without mandatory portal use.

Package API to signature with status channel

We generate tenant-safe PDF/A bundles from Delphi, submit via REST and store signature IDs and timestamps referenceably.

Staff still see pending, signed or declined states in the familiar shell—without forcing an external portal as the primary workspace.

Phased module approval allows gradual introduction of new document types without big bang.

Phase 1: signature pilot per tenant

Pilot tenants test lease signatures; webhook status lands referenceably in FireDAC tables.

PKCS and PDF/A validation before hand-off to the signature platform.

Tenant separation is enforced in bundle generation and status storage.

Support runbook covers typical signature errors and manual retry.

Exports for accounting

Monthly posting batches and AR lists export as CSV/XML aligned with the accounting partner and stored with versioning—auditable end-to-end.

Export error rate is measurably lower than manual spreadsheet handoff.

Versioned exports allow auditors to trace from first click to archived file.

Audit wants to trace the export from first click to archived file.

Operational continuity instead of a big bang

Casework stays in familiar screens; digital evidence and exports are reliable.

Auditors and tax advisors receive reproducible exports; additional document types can follow the same signing pattern.

Signature turnaround dropped; manual portal steps decreased measurably.

Casework sees signature status in the shell without mandatory portal workflows.

KPIs after module approvals

Signature turnaround and manual portal steps dropped; export error rate is measurably lower than manual spreadsheet handoff.

Monthly posting batches run reproducibly with versioning for audit.

Phased module approval allowed gradual rollout across two fiscal years.

Tenant separation and PDF/A validation are audit-documented for auditors and tax advisors.

Webhook status lands referenceably in FireDAC tables without media break for casework.
