Accounting for Consultants and Service Businesses

The books sit in whichever ledger your practice already runs, with a timesheet or billing tool feeding into it. Patron maps every engagement to one code that is carried across both systems, so hours booked, invoices raised and amounts still open reconcile back to a single figure. Journals for accrued income and provisions are posted at close, and accounting for a consultancy ends in schedules an auditor can trace, as project billing for media agencies illustrates.

Where staff book time in arrears rather than daily, effort rises, as it does when live engagements multiply, when retainers sit beside milestone contracts and when registrations span several states at once. Service industry accounting includes each month's close, the engagement schedule, the ledger review and returns filed through the GST portal. Statutory audit, transfer pricing and litigation support are commissioned independently.

Accounting for consultants suits firms that sell time and expertise rather than stock. When revenue is earned before it is billed and staff book their hours after the fact, the businesses below need work in progress valued every month.

• Management and strategy consultancies billing by the hour, carrying unbilled work between one invoice run and the next.
• Creative and media agencies running monthly retainers alongside milestone project fees on a single client.
• Architecture, design and engineering practices valuing work in progress per project before any bill goes out.
• PR and marketing agencies recharging pass-through media and print costs their clients later approve.
• Studios leaning on subcontractors and associates whose cost must sit against the engagement that used them.
• Professional firms where Section 194J TDS deducted by clients must reconcile against Form 26AS.
• Practices taking assignments across several states, applying place-of-supply rules to each engagement.
• Consultancies holding client retainers as advances until the work behind them is delivered.

With no goods to count, the trail for a services firm runs from the engagement letter through the timesheet to the invoice.

• Signed engagement letters, SOWs and retainer agreements with fee basis and milestone terms
• Timesheets / time-tracking export by client, project and person
• Unbilled revenue / work-in-progress schedule and the billing plan for open engagements
• Advance / retainer receipts register showing unadjusted client advances
• Reimbursable / pass-through expense records with client approval and supporting third-party bills
• Subcontractor and associate/freelancer invoices with the engagement terms
• Sales invoices raised, with credit notes and write-offs
• Bank statements for all accounts, and business credit card statements
• Purchase and expense bills: rent, software subscriptions, travel, professional indemnity insurance

For a firm that sells hours rather than goods, Section 128 still defines the books, but the provision that shapes them most in practice is the revenue standard, because the hardest question each month is how much of the work done has actually been earned. The framework around it decides when a service is invoiced, where it is taxed and how the fee is measured.

The answer changes with the contract. A retainer, a milestone and a time-and-materials engagement are recognised differently, so Unbilled Revenue (WIP Hours) is carried where work is ahead of billing, and the Milestone vs Retainer Billing split drives both the ledger and the GST invoice. Accounting for consultants keeps these judgements consistent against the provisions below.

• AS 9 / Ind AS 115Fee income is recognised as the service is performed, with unbilled revenue carried for work delivered but not yet invoiced.
• Sections 12 and 13, IGST Act 2017The place-of-supply rules decide whether a service is intra-state or inter-state, fixing CGST/SGST versus IGST on each invoice.
• Section 194J, Income-tax Act 1961Professional and technical fees attract TDS at 10% (2% for technical services), which the books track against Form 26AS.
• Section 44ADA, Income-tax Act 1961Eligible professionals up to Rs 75 lakh receipts may declare 50% presumptive income instead of maintaining full books.
• Section 128, Companies Act 2013An incorporated agency keeps its books on accrual and double entry at the registered office, retained for eight years.
• Rule 3(1), Companies (Accounts) Rules 2014The audit trail stays enabled, so a revised time sheet or a reclassified retainer leaves a record - the basis of a defensible Project-Wise Profitability Margin. Filing runs from the hub page.

TDS / TCS deposit (Challan ITNS-281) is due 7th of every month (30 April for March). GSTR-1 (outward supplies) is due 11th of every month for monthly filers. GSTR-3B (summary return and tax payment) is due 20th of every month for monthly filers. Patron tracks each against your books so nothing is reconstructed after the fact.

What changes first under accounting for consultants is the middle of the month. Unbilled hours are already valued instead of nothing happening until an invoice run. An engagement running past its budget is flagged while it is still running, and the partner review has numbers in front of it rather than impressions.

Month end under accounting for agencies starts with the engagement schedule rather than the bank. Hours booked convert into a billing decision while the client still remembers the work, and the close lands on figures your partners reviewed first. Recovery on a job is known while that job can still be steered.

We ask how your people record time: daily, weekly or from memory at the end of a job. Then comes the shape of your contracts, and which of them bill on milestones your finance team never sees, a pattern shared with software firms we already support.
