How a Mumbai OOH company eliminated billing disputes by switching from PPT to verified reports using gOGig

A case study from gOGig's OOH partner program. How a mid-sized Mumbai OOH agency operating 740 active sites across the city moved from a PPT-based proof-of-posting workflow to a verified-execution model, eliminated billing disputes, won 4 new enterprise accounts, and grew agency revenue 35% in 11 months.

Billing disputes raised by enterprise clients across 11 months of post-implementation operation. Down from 28 disputes worth ₹42 lakh in the prior 12-month period. The agency's payment cycle compressed from 71 days to 19 days on average.

₹51.4 CrAnnual revenue (post-FEI)
+35.2%Revenue growth

The agency's COO sits across the table from a procurement head at a top-15 listed FMCG client in mid-2024. The conversation is uncomfortable. A 6-week premium campaign across 84 sites in Mumbai. Close to ₹2.1 crore billed. The client's procurement team ran an independent spot-check. 11 sites were not up at the contracted dates. The agency's own report showed 96.4% compliance. The spot-check showed 87.1%. The invoice was contested. The relationship was on the line.

The Mumbai OOH regulatory context in 2025-26

Post Ghatkopar tragedy of May 2024 (17 killed, 75+ injured by a 120 ft x 120 ft illegal hoarding), Mumbai's OOH ecosystem is operating under the strictest regulatory framework in two decades. Agency credibility is now contractual.

Mumbai OOH context (post Ghatkopar)Implication for agency operations
BMC Advertising Guidelines 2025 (notified Nov 2025)First major overhaul since 2008. Whole-of-city compliance reset.
Hoarding size cap 40 ft x 40 ft citywideInventory rationalisation, premium pricing on compliant sites
Footpath and building terrace ads bannedSeveral historical site categories must be vacated
Digital hoarding brightness cap 3:1 luminance, no flickeringDOOH operators retrofit screens and play-out controls
Mandatory structural stability SOPAnnual structural audits by licensed engineers
Mandatory insurance for hoarding + surrounding riskInsurance line item enters every site P&L
Permit lapse window reduced from 6 months to 3 monthsPermit currency tracking becomes mission-critical
Blacklisting regime for repeat violatorsAgency credibility now formally on the line
Mumbai Traffic Police clearance for multi-sided unitsL, V, 3/4/6-sided units need additional NOC

The triggering moment: a procurement conversation in late 2024

"The procurement team at one of our largest FMCG clients told us in late 2024 that from FY 2025-26, every site invoice would need to come with independent verification evidence. They specifically referenced BRSR Core. We had 38 days of campaign in dispute at the time and no way to substantiate. That was the moment we knew the PPT closeout model was finished."

Why PPT closeouts were no longer enough

Limitation of PPT closeout workflowWhy it failed in 2025-26 Mumbai
WhatsApp photos lack server-side timestampProcurement now requires server-verified time
Vendor-uploaded photos cannot be authenticatedEXIF stripping makes photos un-defensible
No night-audit illumination verificationDirect contractual obligation un-evidenced
Closeout deck arrives 3 to 14 days after campaign endDisputes raised before evidence is available
No third-party verification layerProcurement increasingly requires independent attestation
Cannot defend against recycled-photo accusationsImage hash analysis exposes patterns retrospectively
BRSR Core value chain disclosure not supportedListed client base cannot pass agency through assurance
BMC permit currency not auto-trackedPermit lapse window reduced from 6 to 3 months
3-way matching not feasibleProcurement teams refusing payment release
Manual reconciliation eats 240+ hours per quarterOperations team capacity drained on disputes

Strategic outcomes beyond the P&L

01

"Verified by gOGig" partner badge on pitch deck

Used in every pitch from week 14 onwards. Procurement teams cite it as a primary decision factor for shortlisting.

02

BRSR Core readiness for listed FMCG client

7-year audit trail accessible on demand. Listed client's CFO uses agency evidence in limited assurance discussions.

03

BMC compliance posture strengthened

Auto-tracked permit currency, structural NOC, insurance renewals. Zero BMC compliance findings since adoption.

04

Industry press coverage

Agency featured in two media trade publications as an early adopter of OOH verification. Speaking slot at OOH industry conference.

05

Talent acquisition advantage

Operations team retention improved. Sales team confidence higher. Two senior hires from larger competitors specifically cite verification capability.

06

Investor and growth conversations

Agency entered preliminary discussions with two strategic investors. Verified-execution metric in pitch deck enabled credible projections.

PPT closeout vs verified report: the contrast in one campaign

Old PPT closeout workflow

120 site campaign. Closeout deck delivered 11 days post end. 142 photos, vendor-uploaded, EXIF stripped. ₹4.2 lakh in dispute on 8 sites. Resolution took 67 days. Payment delayed 71 days. Operations team spent 28 hours on dispute resolution alone.

FEI verified report workflow

120 site campaign. Real-time dashboard updates throughout. Per-site verified evidence available on demand. Closing memo auto-generated in 14 minutes at campaign close. Zero disputes raised. Payment released in 18 days. Operations team time on reconciliation: 6 hours total.

For 12 years our business depended on agency-grade trust between us and our clients. Verification did not replace trust. It made trust contractually defensible. That single shift changed our agency from a media vendor into an execution intelligence partner.

What the agency would do differently in hindsight

Lesson learnedAction for OOH agencies considering FEI
Start soonerThe procurement conversation forced action. Better to lead than react.
Pilot with one enterprise client firstBetter data, faster learning, easier to scale
Bring vendors into the conversation earlyVendor pushback distribution becomes vendor classification signal
Train sales team on verification narrativePitch deck rebuild matters more than expected
Add verification clause to all new client contractsPBP becomes the default contractual standard
Use BMC compliance as a strategic tailwindRegulatory clock adds urgency procurement teams understand
Co-brand verified report with client logoProcurement teams treat the report as their own evidence
