What we shipped, in plain language.

Under certain conditions, saving a Purchase Requisition was creating duplicate line items. The root cause was a missing uniqueness guard in the SRM model when concurrent saves occurred.

• Added database-level constraint to prevent duplicate PR line items.
• Existing duplicate records can be cleaned up via the admin.

Bulk sync admin actions in the Visitor Management admin panel were crashing with an HTTP 500 error when a visitor record with a duplicate phone number was encountered.

• Admin action now handles IntegrityError on duplicate phone gracefully — the conflicting record is skipped and logged rather than aborting the entire sync batch.
• A summary of skipped records is shown in the admin success message.

The component filter for Accessory and Packaging cost elements in Textile Costing was not applying correctly, causing all components to be shown regardless of the selected filter.

• Filter logic corrected in the costing views; only components matching the selected type are now returned.

The Goods Movement admin list view was returning an HTTP 500 error due to a missing field reference after a recent model change in the Materials Management module.

• Admin list_display updated to reference the correct field names after the MM model refactor.

The Terry Fabric costing results page was rendering blank due to a template context key mismatch introduced during the v1.90.0 release.

• Template updated to use the correct context variable names.
• Terry Madeup results now render correctly with all cost components.

Minor UX improvements to the Visit Request creation form.

• Visitor search field now triggers more reliably on partial input.
• Form validation messages are displayed inline for faster correction.

The service worker registration script was being injected into marketing website pages, causing unexpected caching and navigation overrides. Registration is now guarded to fire only within the React application shell.

WHITENOISE_INDEX_FILE was set to True, causing WhiteNoise to intercept root-path requests and serve the React index.html instead of the Django-rendered marketing website. Disabling this setting restores correct behaviour.

The service worker navigation handler previously intercepted requests to /tenant-admin/, causing the Django admin interface to serve the React shell instead of the admin pages. The navigation fetch handler now explicitly excludes /tenant-admin/ from its scope.

The global ToastContainer auto-close delay was previously set too short, causing important error and warning toasts to disappear before users could read them. The default is now autoClose={false} — toasts persist until dismissed.

A series of usability and data-quality improvements to the Inventory Management module.

• Improved stock movement history with drill-down to source document (GR, GI, Transfer Order).
• Enhanced bin/location assignment UI for warehouse operations.
• Batch expiry alerts and low-stock threshold notifications.

The service worker and WebSocket notification layer are now active in the production environment, enabling push notifications and offline capability for all portal users.

Resolved an issue where the digital signature block was not rendering correctly on exported Sales Invoice PDFs, resulting in a blank or misaligned signature area.

Multiple usability and workflow improvements to the Purchase Requisition process.

• Improved line-item entry with inline validation and auto-fill from the materials master.
• Enhanced status tracking with approval-stage badges.
• Bulk approval action for procurement managers.

The employee Family Tree view in HRM has been improved with additional relationship types, better node rendering for large families, and an export-to-PDF option.

The Visitor Management System now sends real-time notifications to hosts when a visitor checks in, and includes several UX improvements.

• Push Notifications — WebSocket / browser push alerts sent to the host employee on visitor arrival.
• Badge Printing — improved visitor badge layout with QR-code for re-entry scanning.
• Search & Filter — visitor log search by name, company, and visit date with export to Excel.

A new Terry Fabric costing sheet has been added to the Textile Costing module, enabling detailed cost calculation for terry-weave fabrics (towels, bathrobes, etc.).

• GSM & Pile Calculation — ground and pile yarn consumption computed from fabric construction parameters.
• Full Cost Build-up — yarn, weaving, dyeing, finishing, and packing costs consolidated into a single sheet.
• Approval Workflow — follows the same TC User → TC Manager → Commercial Head approval chain.

• Web App Manifest — app icon, splash screen, and standalone display mode configured for both platforms.
• Install Prompt — in-browser install banner guides users through adding the app to their home screen.

A dedicated What's New / Change Log page has been added to the supplier portal, surfacing public release notes so suppliers can track new features and improvements without leaving the app.

The supplier discovery page now displays aggregate review ratings and risk score badges on supplier cards, helping buyers make informed connection decisions.

Supplier portal users can now sign in using their Google or Microsoft accounts via OAuth 2.0.

• Provider Support — Google and Microsoft OAuth with configurable client ID and secret in Django settings.
• Social Account Linking — a SocialAccount model tracks linked providers per user, supporting multiple linked accounts.
• Auto-Provisioning — new supplier users are auto-created on first OAuth login when their email matches a registered supplier domain.
• Login Page — redesigned supplier login page with social sign-in buttons alongside traditional email/password.
• Callback Handling — dedicated OAuth callback page handles token exchange and error states.

New Celery Beat tasks for automatic recalculation of supplier risk scores and analytics aggregates on a configurable schedule, ensuring dashboards stay up to date without manual intervention.

Comprehensive help documentation migrations added for Phase 4 (procurement collaboration), Phase 5 (ratings, risk, analytics), and Phase 6 (OAuth/SSO, enhanced discovery) features.

Suppliers can now view their own performance analytics from the portal, including order volume, on-time delivery rate, review scores, and revenue trends across connected buyers.

Buyers can submit per-transaction reviews of suppliers with star ratings across four dimensions.

• Four Dimensions — Quality, Delivery, Communication, and Value, each rated 1–5 stars; auto-calculated overall rating.

A long-standing infrastructure issue where Django's migration framework would generate spurious (phantom) migrations for GCSFileField and GCSImageField columns on every makemigrations run has been resolved.

• The custom field's deconstruct() method now correctly serialises all field parameters, preventing unnecessary migration diffs.
• All previously missing GCSFileField migrations have been added across the affected apps.
• The CI/CD pipeline now enforces a migration check stage — any unapplied migration will fail the build, catching drift before it reaches production.

A migration conflict on GCSImageField and GCSFileField columns that caused migrate to fail on fresh tenant databases has been fixed.

• Root cause: the field's storage backend parameters were being included in the migration state, causing the field signature to differ between environments.
• Affected migrations have been corrected so that new tenant database provisioning and CI test runs complete without errors.

The AI engine that converts incoming Purchase Orders from customers into Biztimize Sales Orders has been significantly enhanced:

• Improved line-item extraction accuracy for complex multi-page POs.
• Better handling of variant materials (size/colour grids) during auto-population of order lines.
• Reduced false-positive mismatches when mapping customer material codes to internal material masters.
• Enhanced error reporting when the AI cannot confidently match a line — the user is prompted to review rather than silently creating an incorrect order.

A brand-new Visitor Management System is now live, giving organisations a complete digital front-desk solution. Key features:

• Pre-Registration & Visit Requests — hosts invite visitors in advance with purpose, schedule, and access zones; requests go through an approval workflow (Draft → Pending → Approved).
• QR-Code Fast Check-In — every approved visit generates a unique UUID-based QR pass; security scans or types the code for instant check-in.
• Walk-In Registration — a streamlined single-screen form creates the visitor record and checks in the visitor simultaneously.
• Active Visitors Dashboard — real-time table of everyone currently on premises, with one-click checkout.
• Host Notifications — the host employee is notified (in-app and email) the moment their visitor checks in.
• Visitor Master Records — searchable visitor database with visit history, linkage to CRM Customers and SRM Suppliers, and ID proof capture (Aadhaar, PAN, Passport, Driving License, etc.).
• Badge & Pass Management — configurable badge templates (colour-coded by visitor type), pre-printed card number mapping, and badge return tracking at checkout.
• Blacklist / Watchlist — flagged visitors are blocked at check-in; admins can lift bans with an audit trail.
• Compliance Forms — location-specific mandatory forms (Safety Induction, NDA, Health Declaration, PPE Acknowledgement) with digital signature recording.
• Multi-Location Support — independent configuration (compliance rules, auto-checkout hours) per gate or premises.
• Analytics KPIs — dashboard shows expected, checked-in, checked-out, currently-inside, no-show, and pending-approval counts for today, with visitor-type and location breakdowns.
• Excel Export — full visit log history exportable to Excel for compliance and management reporting.

Access is controlled by new VMS roles: VMS Security Guard, VMS Host, and VMS Admin. Post-deploy: run python manage.py setup_rbac --tenant <id> and assign roles in Django Admin.

The HRM Payroll module now has a dedicated React frontend. Payroll administrators can access payroll runs, payslips, and related management screens directly from the sidebar without switching to the Django admin or legacy views.

• Payroll list and detail pages integrated into the main React application.
• Consistent navigation and styling matching the rest of the Biztimize UI.
• Role-based access gates apply — only users with payroll permissions see the new sidebar entries.

The FnF Service automates the settlement calculation when an employee exits:

• Pro-rated salary for the partial last month
• Leave encashment calculation (earned leave balance × daily rate)
• Gratuity computation (15/26 formula per Indian Gratuity Act)
• Outstanding loan and advance recovery
• FnF payslip generation and approval workflow integration

The Payslip Service produces a structured payslip for each employee after a payroll run is completed:

• Earnings and deductions breakdown by wage type
• Employer contribution summary (PF, ESI)
• Year-to-date totals and tax summary
• PDF download available from the employee self-service portal
• Bulk payslip email dispatch supported

The India Country Pack implements all four statutory deduction calculators required for India payroll:

• TDS (Income Tax) — old vs new tax regime, standard deduction, HRA exemption, 80C/80D deductions, surcharge and cess, month-wise TDS equalisation
• Provident Fund (PF / EPF) — employee 12 % + employer 12 % contribution split (EPF + EPS), wage ceiling enforcement, VPF support
• ESI (Employee State Insurance) — employee 0.75 % + employer 3.25 %, gross wage ceiling check, monthly eligibility validation
• Professional Tax (PT) — state-wise slab tables, monthly cap enforcement, exempt category support

Additional country packs can be registered via the pluggable CountryPackRegistry without modifying core engine code.

The core Payroll Engine orchestrates the full payroll calculation cycle for a Payroll Period:

1. Eligibility check — identifies employees in scope based on assignment and attendance data
2. Gross calculation — builds the pay register from Basic Pay (IT0008), Recurring Payments (IT0014), and Additional Payments (IT0015)
3. Proration — pro-rates salary for mid-period joiners, leavers, and loss-of-pay days
4. Country-pack execution — applies statutory deductions and employer contributions
5. Net pay derivation — gross minus all deductions
6. Payroll result persistence — stores employee-level and summary results

Payroll Runs follow a lifecycle: Draft → Running → Completed → Approved → Disbursed. Re-runs are supported in Draft and Completed states.

The Gross Calculator builds a per-employee wage-type breakdown before statutory deductions:

• Reads active IT0008 (Basic Pay) compensation components for the period
• Adds all active IT0014 (Recurring) components matching the payroll frequency
• Adds all IT0015 (Additional) one-time payments scheduled for the period
• Applies attendance-based proration via the Proration Service
• Outputs a gross pay register used by the country pack and payslip generator

Twelve end-user and administrator help articles added under the HRM – Payroll Engine category:

1. Payroll Engine Overview & Architecture
2. Running the Monthly Payroll Cycle
3. India Country Pack – TDS / Income Tax
4. India Country Pack – Provident Fund (PF / EPF)
5. India Country Pack – ESI (Employee State Insurance)

A dedicated Tax Engine model layer stores country-level payroll tax configuration that can be updated by HR administrators without code changes:

• TDS slab tables for old and new tax regimes (annually updatable)
• PF/ESI wage ceiling and rate configuration
• State-wise Professional Tax slab tables
• Standard exemption and deduction limits (80C, 80D, HRA)

The Bank File Service generates payment instruction files for salary disbursement:

• NEFT/RTGS bulk payment file in standard bank formats
• Per-employee net pay with bank account details
• Deduction payment files for PF, ESI, and PT challan generation
• Downloadable from the Payroll Run detail page after approval

After payroll approval, the GL Posting Service automatically creates journal entries in the Financial Accounting module:

• Salary expense lines per wage type and cost centre
• Statutory liability lines (PF payable, ESI payable, TDS payable)
• Net pay payable to employees
• Employer contribution expense lines
• GL account mapping configured via the Payroll Control admin page
• Reversal support for corrective payroll runs

Off-Cycle Runs allow ad-hoc payroll processing outside the regular monthly schedule — for advance payments, bonus payouts, interim settlements, and corrections without waiting for the next regular cycle. Off-cycle runs go through the same engine pipeline but are tagged separately in GL posting and disbursement files.

The Arrears Service recalculates pay differences when salary revisions are applied retrospectively:

• Detects periods where the employee's compensation changed mid-cycle
• Recomputes gross and net pay for each affected period
• Generates an arrears adjustment record for the current payroll run
• Full audit trail: old pay, new pay, and delta per wage type
