The Problem

Timesheet Mismatches

Contractors submitted hours through email and spreadsheets. Client-side approvals arrived through a separate channel, creating chronic mismatches that triggered billing disputes on nearly one in three invoices.

Fragmented PO Tracking

Client purchase orders were stored in email threads and local Excel files. Finance had no real-time view of consumed PO value, so invoices were raised against expired or over-utilised POs, prompting rejections and delayed payments.

Revenue Leakage

Approved overtime hours and billable expenses were routinely missed during manual invoice preparation. The accounts team estimated leakage of Rs22 lakh per year, but had no tooling to identify or recover it systematically.

Solution Stack

Core HR
Zoho People
Timesheets, Attendance, Contractor Lifecycle

Contractors were onboarded into Zoho People’s contractor management platform with structured timesheet workflows. Each timesheet entry is mapped to a client project and job code. Client-side approvers receive an email link and approve directly in the portal, creating a single auditable trail. Overtime and weekend hours are flagged automatically for billing markup.

Finance
Zoho Books
Client PO Ledger, Invoice Automation, TDS Compliance

Approved timesheet data flows directly into Zoho Books client invoicing via native integration. PO value and utilisation are tracked per client per project. Invoices are generated automatically once timesheets are approved, with TDS deduction on contractor payments and GST on service invoices handled within the same workflow. Billable expense claims from contractors are validated against client contracts before inclusion.

Analytics
Zoho Analytics
Dispute Dashboard, PO Burn Report, Billing Leakage Tracker

Three custom dashboards give the leadership team a live view of dispute ageing, PO consumption rates, and unbilled hours. A weekly leakage alert report flags approved hours not yet included in any open invoice, enabling the finance team to act before month-end close.

Implementation Phases

Phase 1
Discovery and Process Mapping
Weeks 1 to 2

Aaxonix mapped all existing timesheet, PO, and invoice workflows. Dispute root causes were classified across three categories: approval delays, PO mismatch, and unbilled hours. Client contracts were reviewed to extract billing rules, markup structures, and TDS applicability.

Phase 2
Zoho People Configuration
Weeks 3 to 6

Contractor records were migrated into Zoho People. Timesheet forms were configured with mandatory fields: project code, client PO reference, and work type. Approval chains were set up for 14 active client accounts. PF and ESI compliance rules were applied for contractors on the payroll. Attendance integration was enabled for onsite contractors using biometric data export.

Phase 3
Zoho Books Setup and Integration
Weeks 7 to 10

Client POs were entered into Zoho Books as purchase order records with line-item value tracking. Service items were mapped to HSN codes and GST rates. TDS deduction rules were configured by contractor type. The Zoho People to Zoho Books integration was activated and tested across three billing cycles. Invoice templates were customised to include timesheet summary attachments requested by enterprise clients.

Phase 4
Zoho Analytics and Reporting
Weeks 11 to 12

Three dashboards were built: a dispute tracker, a PO burn report by client, and a billing leakage alert report. Scheduled email reports were configured for the CFO and operations head every Monday morning. Data from the prior six months was back-loaded for trend comparison.

Phase 5
Training, UAT, and Go-Live
Weeks 13 to 14

Finance, operations, and recruitment coordinators completed role-based training. Contractors received a one-page guide for portal timesheet submission. Two billing cycles were run in parallel before the legacy system was decommissioned. Go-live was declared at the start of week 15.

What Made the Difference

The root cause of invoice disputes in IT staffing is almost never a billing error. It is a data synchronisation problem. When client approvals, contractor hours, and PO balances live in three separate tools, reconciliation becomes a manual activity, and manual activities fail at scale. Connecting Zoho People to Zoho Books removed the reconciliation step entirely. Timesheets approved by the client became invoices without a human touch point in between. Dispute resolution shifted from reactive to proactive because the analytics layer surfaced mismatches before invoices were raised, not after they were rejected.

Frequently Asked Questions

Can Zoho People handle TDS compliance for contract workers paid through the firm?
Yes. TDS deduction on contractor payments (under Section 194C or 194J depending on engagement type) is configured in Zoho Books against each vendor or contractor record. When payment runs are processed, the applicable TDS rate is deducted automatically and the challan data is available for quarterly return filing. Zoho People manages the attendance and timesheet data upstream, while Books handles the financial compliance downstream.
What happens when a client PO is nearly exhausted mid-month?
Zoho Books is configured to trigger an alert when PO utilisation crosses 80% of the sanctioned value. The account manager receives an automated email with the current consumed amount and remaining balance. This gives the team time to request a PO amendment or pause billing before hitting the ceiling and triggering a client dispute. The PO burn report in Zoho Analytics gives daily visibility across all active client accounts.
How does GST on staffing service invoices work inside Zoho Books?
Each billable service item (staff augmentation, dedicated resource billing, project-based engagement) is mapped to the correct HSN or SAC code and the applicable GST rate inside Zoho Books. When an invoice is generated from approved timesheet data, GST is calculated and applied automatically. For clients with reverse charge applicability, the system flags the invoice accordingly. GSTR-1 data is exported monthly for return filing through the GSTN portal.
Is it possible to give clients a portal view of their active PO utilisation and approved timesheets?
Zoho Books includes a client portal where customers can view invoices, make payments, and access shared documents. For timesheet visibility, Zoho People supports external approver access without requiring a full user licence, which means client managers can log in to approve contractor hours directly. Some firms augment this with a Zoho Creator custom portal for enterprise clients who want a consolidated view of PO balance, timesheet history, and invoice status in one place. Aaxonix has built and deployed such portals as part of larger staffing engagements.
