Releases

What's shipped.

July 2026 The give-aways & the growth engine
  • Sign-off document manifest: every lock records the documents dated in the period, so a re-date shows its original date ("was dated 30 Jun, now 1 Jul") and a void or delete after sign-off becomes a named finding
  • Free Drift Report: scan your last 6 closed months for backdated changes, no lock or baseline needed; whole-book variant for practices
  • Close-window slider on the Drift Report: normal close activity excluded, tiered "worth checking" vs drift
  • Year-End Assurance Report: do the accounts you filed still agree with Xero? Verdict, line-by-line comparatives, audit-bundle Excel
  • Practice dashboard re-anchored on each client's filed year-end; monthly management accounts optional per client
  • Roll-forward Excel pack: live formulas, spare rows, GL tie-outs; download once, use forever
  • Free templates library: prepayments, accruals, fixed assets, bank rec, close timetable (no sign-up)
  • Free materiality calculator: the product's exact threshold logic, reasoning shown
  • Handover export: every balance's carried-forward memo in one standalone file
  • Fix-list export: branded "here's what changed and what we need" file to forward to a client
  • Board one-pager: declared figures + verdicts, print-ready
  • Alert emails + morning digest (immediate / daily / weekly), one-click unsubscribe
  • Live demo without sign-up, in real deployments too
June 2026 Billing & compliance
  • Stripe billing: 14-day trial, read-only gate for lapsed accounts
  • Email verification: new signups blocked until confirmed
  • Per-account Xero API cap + short caching (abuse controls)
  • UK GDPR: privacy policy, terms, data export and right to erasure
  • Owner ops dashboard: cross-account usage, engagement and billing view
  • Production hardening: 30-day sessions with per-device revocation
  • CSV formula-injection defence on journal and audit exports
  • Render deploy blueprint + Dockerfile + SQLite persistent storage on DATA_DIR
June 2026 Multi-user & multi-tenant
  • Named users with scrypt-hashed passwords and signed session cookies
  • Roles: admin / reviewer / preparer / viewer with a permission matrix
  • Optional two-person approval workflow: segregation of duties
  • Full multi-tenancy: each account has isolated data, zero cross-account leakage
  • Onboarding flow: baseline a starting month, Postlock watches forward from there
June 2026 Integrity & close
  • Integrity split into 4 views: Summary, Changes, Board figures, Documents
  • Inherited-change banner: prior-period drift surfaced during the current close
  • Materiality thresholds: % of benchmark / fixed £ / every-change; with trivial floor, aggregate check, and always-flag override
  • Post-lock P&L restatement: "profit was £25,410 when you signed off, now £24,760"
  • Auditor export CSV: every change with handling and the control log
  • Stable account-ID change detection: renames never false-alert
  • Supporting schedules: movement / proof / static, with auto roll-forward
  • Evidence attachments per rec line: images embed in the Excel pack
  • Monitoring watchdog: sweeps locked periods on a timer, raises in-app alerts
June 2026 Design & marketing
  • Marketing site redesign: shared postlock.css design system, Newsreader serif, ledger green + gold
  • App re-skinned onto the same design system: sidebar IA, two product areas
  • Cornerstone guide content: Xero month-end checklist, balance sheet reconciliation, closed period changes, prepayments & accruals
May 2026 Core close
  • Guided balance-sheet close with per-line status, note, institutional-memory carry-forward
  • Period lock with snapshot: every balance captured at sign-off
  • Post-lock change detection with document scan, who/when from Xero history
  • Open-in-Xero deep links for each detected change
  • Per-change actions: Open in Xero, Correct via journal, Acknowledge with reason
  • Journal CSV template: Xero import format with named, dated entries
  • Board-pack figures: declare and track headline numbers across periods
  • Excel rec pack: cover, balance sheet, rec index, schedules, post-lock changes
