How Much Does Custom Oil & Gas and HSE Software Cost? (2026 Guide)
Real price ranges for custom oil and gas and HSE software, what makes projects cost more, and how to budget for running costs.
Typical cost by module
These are the ranges Stacklyn quotes for a single site. Every project is scoped individually, but most land inside these bands.
| Module | Typical build cost | Typical timeline |
|---|---|---|
| Digital permit to work | $6,000–12,000 | 8–12 weeks |
| HSE incidents, audits & inspections | $6,000–12,000 | 8–12 weeks |
| ICV / localisation reporting | $5,000–12,000 | 6–10 weeks |
| Crew rotation & competency tracking | $5,000–10,000 | 6–10 weeks |
| Document control & vendor portal | $6,000–12,000 | 8–12 weeks |
| Operations & production dashboards | $7,000–14,000 | 8–12 weeks |
| Integrated platform (several modules, multiple sites) | $25,000–85,000 | 4–9 months, in phases |
What drives the price up
Two projects with the same module name can differ widely in cost. The main drivers are:
- The number of permit types, workflows, and approval levels.
- Integrations with existing systems such as SAP, Maximo, Tally, or process historians.
- Offline mobile apps for sites without reliable connectivity.
- Arabic and English interfaces with right-to-left layouts, which typically add around 15%.
- Multiple sites or clients with different formats and rules.
- Migrating historical data from spreadsheets or older systems.
- Hosting inside a specific country, and security reviews required by your clients.
Running costs after launch
Cloud hosting for systems of this kind typically costs $20–300 per month, depending on users and data volume. Ongoing support is optional and can be a monthly retainer or ad hoc work. If the system uses AI models or WhatsApp messaging, that usage is billed separately at the provider's rates.
A common rule of thumb is to budget 15–20% of the original build cost each year for improvements and maintenance, although simple systems often need less.
India-based team, local agency, or in-house?
Each option has a place. The right choice depends on budget, control, and how specialised your workflows are.
| Option | Cost | Strengths | Watch out for |
|---|---|---|---|
| Specialist team in India | Lowest — Stacklyn charges $65–95 per hour, or $2,500–4,000 per month for a dedicated developer | Lower cost, industrial workflow experience, good time-zone overlap with the Gulf | Check domain knowledge, security practices, and IP terms |
| Local agency (Gulf, UK, US) | Typically several times higher hourly rates | On-site presence and local contracts | Often generalist teams unfamiliar with permits or HSE |
| In-house team | Salaries, hiring, and management for a whole team | Full control and long-term knowledge | Slow to hire and expensive for a single product |
Off-the-shelf SaaS or custom software?
Off-the-shelf SaaS is usually cheaper to start when your processes match the product. Per-user and per-site subscription fees add up over time, though, and you adapt your procedures to the product rather than the other way round.
Custom software makes sense when your workflows or client formats are unusual, when you need deep integration with existing systems, or when you want to own the system and its data outright. Many companies combine the two: SaaS for standard functions and custom software for the workflows that make them different.
How to keep the cost down
- Start with one module on one site as a pilot.
- Configure existing features instead of building new ones where you can.
- Integrate with the systems you already have rather than replacing them.
- Agree fixed-price phases so scope and cost stay predictable.
- Involve the people who will use the system from the first demo.
