How a North American tradeshow company cut post-show billing from 3 weeks to 2 days with Odoo

The challenge

Managing 50+ overlapping convention calendars across the United States, with hundreds of traveling crew members and shared rental assets, pushed the client's paper-based systems past their limits.

Every show produced a stack of hand-written Daily Time Tickets covering Straight Time (ST), Overtime (OT), and Double Time (DT), each rate tier governed by strict union and venue rules. Re-entering those tickets into invoices took 2–3 weeks per show and introduced errors that led to billing disputes on nearly 1 in 5 invoices. At the same time, modular booth hardware, truss systems, monitors, and hanging signs were scheduled manually, creating double-booking risks during peak convention season. Crew travel (flights, hotels, Vrbo rentals, rental cars, and daily per-diem) was booked outside any system, so real-time show cost tracking was impossible. Missing Certificates of Insurance (COI) and unsigned Material Handling Agreements (MHA) caused further invoice delays and cash collection bottlenecks.

Why Odoo and Why GritXi?

The client needed a single platform that could manage the full show life cycle, from initial quote and crew scheduling through to mobile field time capture, digital inspection sign-offs, and automated finance sync. Generic ERP systems could handle parts of this, but none understood the show-floor labor rules (ST/OT/DT tiers), the rental asset cycle, or the convention-specific compliance requirements (COI, MHA).

They chose Odoo 17 because it offered the flexibility to build truly custom workflows on top of a solid ERP core, with inventory, accounting, and project management in one database. They chose GritXi because GritXi had already built specialized Odoo modules for tradeshow operations, including the labor rate engine and digital signature workflows that no off-the-shelf system provided.

The approach

GritXi engineered a suite of purpose-built Odoo modules covering every stage of a show:

Show & venue management

A master show record tracks Move-In, Show Dates, Move-Out deadlines, venue decorators, and hall locations. City Managers, Supervisors, Lead Technicians, and Account Coordinators are assigned per show. COI validation is enforced before booth construction can begin, so permits require confirmed insurance.

Exhibitor job execution

Each exhibitor booth has a live status pipeline: Ready for Install → Working on Install → Install Complete → Ready 100% → Working on Dismantle → Dismantle Complete → MHA Turned In. Booth specs (dimensions, flooring, hanging signs, monitor sizes, warehouse delivery status) and electrical readiness are tracked per job, so account managers and field crews see the same live status.

Field timesheets and automated daily time tickets

Field supervisors log crew hours directly on smartphones and tablets on the show floor. The system automatically calculates ST, OT, and DT based on shift hours and venue-specific rules. One click generates a Daily Time Ticket (DTT) with a digital signature line where the client signs on-glass, archiving the approved DTT instantly. No paper. No lost slips. No re-entry.

Digital quality checklists

Structured check-in and check-out forms cover wood crates, skids, fiber cases, flooring condition, and courier shipments. Dual digital signatures from the Lead Technician and City Manager are captured before handover to the exhibitor, creating an audit trail that replaces paper inspection reports.

Travel and accommodation logistics

A centralized travel module handles requests and manager approvals for flights, hotels, Vrbo rentals, rental cars, and daily per-diem, all tied directly to the show's analytic account so real-time show cost is always current.

Finance and cloud integrations

Approved invoices and expenses sync automatically to QuickBooks Online with no double entry or batch uploads. Booth blueprints, graphic proofs, signed DTTs, and COIs are filed automatically into structured Microsoft SharePoint directories, accessible from any device.

Implementation timeline

Total go-live timeline: 11 months from project start to production.

The results

A story from the show floor

At a large Las Vegas convention, a dispute over crew overtime charges had previously taken 11 days to resolve because the paper Daily Time Tickets were partially lost and the account manager had to manually reconstruct hours from crew memory and partial records. The show invoice was delayed by nearly two weeks and the client relationship was strained.

After go-live, the same scenario played out differently. A supervisor flagged an OT query from an exhibitor on the show floor. The account manager pulled up the digital DTT on screen, showing time-stamped entries, the calculated OT breakdown, and the exhibitor's own on-glass signature from that morning. The dispute was closed in 20 minutes. The invoice was raised the same afternoon.

What the client said

Publish only after written client approval of this quote (or a signed anonymized version). Also confirm a second voice quote if available, such as a City Manager or field supervisor.
