The verdict in three sentences
For a Miami outdoor advertising company operating 1,800 billboard faces and 40 digital screens, custom inventory and booking software costs, as a 2026 order of magnitude, USD 40,000 to 80,000 and ships in about 4 months. It replaces the shared spreadsheet with a map of locations showing availability by period, generates PDF proposals in minutes and tracks posting orders through to photo proof of performance. The gain shows up in the occupancy rate, which commonly rises by 8 to 12 points once sales reps finally see available inventory in real time.
What the software must cover, module by module
A spreadsheet works while two reps sell complete networks. It breaks as soon as you sell by the week, by neighborhood, with screens whose inventory is split into 8 or 10 second spots. Double bookings and forgotten faces then cost entire campaigns.
| Module | Core version | Full version |
|---|---|---|
| Location database (format, address, illumination, audience) | USD 4,500 | USD 8,000 |
| Interactive map with filters by area, format and period | USD 5,500 | USD 10,500 |
| Availability and holds by 4-week period | USD 7,000 | USD 12,500 |
| Digital inventory by slot and loop share | USD 6,000 | USD 11,500 |
| PDF proposals and rate cards | USD 4,500 | USD 8,500 |
| Posting orders, crew scheduling and geotagged photo proof | USD 6,000 | USD 11,500 |
| Contracts, invoicing and accounting integration | USD 4,000 | USD 9,000 |
| Testing, spreadsheet migration and go-live | USD 2,500 | USD 8,500 |
| Total | USD 40,000 | USD 80,000 |
Data migration is often underestimated: 1,800 faces with GPS coordinates, photos, formats and campaign history mean 3 to 5 weeks of cleanup if the spreadsheet holds duplicates and approximate addresses.
Off-the-shelf software or custom build
Specialized tools exist for out-of-home advertising. The choice depends mainly on the share of digital and the company's commercial specifics.
| 2026 option | Upfront cost (order of magnitude) | Recurring cost | Main limit |
|---|---|---|---|
| Shared spreadsheet and PowerPoint proposals | USD 0 | 1 to 2 days a week of updates | Double bookings, no real-time visibility |
| SaaS out-of-home software | USD 6,000 to 18,000 setup | USD 900 to 3,000 a month depending on faces | Little room for local pricing rules |
| Programmatic DOOH platform only | Low | 10 to 20 % commission on programmatic sales | Does not handle static boards or posting |
| Adapted general-purpose CRM | USD 9,000 to 22,000 | USD 50 to 150 per user per month | No concept of face, period or map |
| Custom software | USD 40,000 to 80,000 | Maintenance and hosting, USD 6,000 to 10,000 a year | Investment, rigorous scoping |
A custom build makes sense when the company mixes static and digital, sells tailored packages and wants to expose availability to media agencies through a portal or an API.
The metrics to track after go-live
Booking software is managed with a few simple figures:
- Occupancy rate by network and period, the metric that funds the project.
- Response time to a proposal request, which often drops from 2 days to under 2 hours.
- On-time posting rate, verified by photo proof.
- Share of faces never sold over 12 months, to reposition or renegotiate with landowners.

Carlos, sales director of an outdoor advertising company in Miami (fictional illustrative case), sells 1,800 faces at an average of USD 1,100 per face per 4-week period, i.e. 13 periods a year. Current occupancy is 58 %. Potential revenue at 100 % reaches USD 25.7 million.
He invests USD 62,000 in the software. Assuming a cautious 8-point rise in occupancy, the company sells about 1,870 more face-periods a year, i.e. USD 2.06 million of additional revenue, before agency discounts and site leases. Even keeping only 10 % of that amount after leases and posting costs, the gain exceeds USD 200,000 a year. The project pays back in under 4 months.
FAQ
How long does deployment take?
Allow about 4 months as a 2026 order of magnitude: 3 weeks of scoping, 10 to 12 weeks of development and 3 weeks of testing with sales reps and posting crews. Migrating the 1,800 faces runs in parallel.
Can the software handle digital screens and static boards together?
Yes, each location carries its type: a static face is sold by period, a screen by slot in a loop of 6 to 10 advertisers. The proposal combines both in a single PDF with an overall price.
Can media agencies check availability?
Yes, a secure portal or an API shows them open faces, formats and public rates. Companies that open one often cut availability-request emails by 30 to 40 %.
How does photo proof work?
The crew member takes a photo in the mobile app, timestamped and geotagged, automatically attached to the posting order. The advertiser receives a full proof of performance report within 48 h, which limits invoice disputes.
Are local sign regulations taken into account?
The software can store each location's constraints under county and municipal sign codes: maximum size, digital dwell time and brightness limits, protected zones. This feature adds USD 2,500 to 4,500 to the budget and prevents selling a non-compliant face.
