MRO software manages maintenance work and airworthiness: aircraft and component status, work orders, task cards, sign-offs and maintenance records. "Aviation maintenance software" is the broader umbrella term, from simple tracking tools to full MRO systems. An ERP manages the business: finance, purchasing, HR, sales and invoicing. Most maintenance organisations need both sides. The real decision is whether you run them as separate, integrated systems or as one platform.
Three terms, three scopes
| Term | What it manages | Typical users |
|---|---|---|
| Aviation maintenance software | Any software for aircraft maintenance: tracking, planning, execution, records | Operators, CAMOs, MROs, flight schools, business aviation |
| MRO software (also M&E software) | The maintenance process end to end: programme, ADs, components, work orders, task cards, stores, tools, certification | Airlines, Part-145 and FAA Part 145 organisations, component and engine shops |
| ERP | Company resources: accounting, purchasing, sales, HR, payroll, assets, reporting | Any company, in any sector |
One warning about search terms. In industry in general, "MRO" also means "maintenance, repair and operations": spare parts and consumables for factories, managed with maintenance management (CMMS) or asset management (EAM) software. In aviation, MRO means maintenance, repair and overhaul of aircraft, engines and components, under the rules of an aviation authority. This guide uses the aviation meaning.
What MRO software does
MRO software is built around the aircraft and its regulated records. It knows concepts that a generic system does not:
- Airworthiness status: hours, cycles, inspections, ADs, modifications and life-limited parts of each aircraft, engine and component.
- Maintenance programme: tasks with intervals in hours, cycles and calendar time, and forecasts from real utilisation.
- Execution: work orders, routine task cards and non-routine cards (NRCs), see work orders and task cards.
- Authorised sign-offs: certifying staff, Part-66 licences, type ratings and company authorisations.
- Traceability: part and serial numbers, release certificates (EASA Form 1, FAA 8130-3), tools and calibration.
- Regulated records: the evidence required by EASA Part-145, Part-CAMO or FAA Part 145, with retention and audit trail.
Within this category there are two orientations. Systems for operators and CAMOs (often called M&E) focus on the fleet: maintenance programme, engineering, reliability and planning. Systems for maintenance providers focus on the customer job: quotes, work orders, hangar or shop capacity, materials and invoicing for hours and parts. Some products cover both.
Aviation maintenance software: the wider category
Aviation maintenance software includes full MRO systems and also smaller tools. Business aviation operators often use maintenance tracking services that keep the due list and logbook records, without hangar execution or stores. Small MROs sometimes run only a task card tool and keep the rest in spreadsheets.
These tools can be enough for a small fleet. They fall short when you need to connect tracking, execution, material and invoicing. Our guide on how to choose aircraft maintenance tracking software covers the criteria in detail.
What an ERP does, and what it does not
An ERP is the system of record for the business: general ledger, accounts payable and receivable, purchasing, sales, HR, payroll, fixed assets and tax compliance. Large ERP suites are robust and cover many countries and legal entities.
A generic ERP, however, does not usually understand the maintenance regulations out of the box. It has no notion of an AD, a life-limited part, a recurring inspection or a Part-66 authorisation. You can configure or extend it, but that is a development project, and the regulated records then depend on that custom work.
Some vendors combine both worlds. IFS, for example, sells its ERP and the Maintenix maintenance product, which it acquired with Mxi Technologies in 2016. Ramco positions its aviation suite as covering engineering, maintenance, supply chain and finance on one platform.
MRO ERP: one platform or two integrated systems?
"MRO ERP" usually means a platform that covers maintenance and the business processes together. The alternative is a specialised MRO system integrated with a separate ERP.
| Aspect | MRO system + separate ERP | Single MRO ERP |
|---|---|---|
| Fit with existing IT | Keeps the corporate ERP the group already uses | Replaces several systems with one |
| Data flow | Hours, materials and costs move through interfaces | Hours booked on a task are the same hours in HR and on the invoice |
| Maintenance cost of IT | Two vendors, two upgrade cycles, one integration to maintain | One vendor and one data model |
| Best for | Large airlines and groups with a corporate ERP standard | Small and mid-sized MROs, operators and CAMOs without a large IT team |
| Main risk | Integration gaps: data entered twice or out of sync | Weak business modules if the platform is only strong in maintenance |
When each option fits
- A tracking tool fits a small fleet or a business aviation operator that contracts all maintenance out.
- A specialised MRO or M&E system plus your corporate ERP fits a large airline or a group that must keep a corporate ERP, and has the IT team to run the integration. See our AMOS vs SkyPlannerHub comparison for an example of this approach.
- A single MRO ERP fits an independent MRO, a line maintenance provider, a base maintenance hangar or a component shop that wants one source of truth from the task card to the invoice.
- A generic ERP with custom maintenance modules is rarely a good idea for regulated maintenance, unless you have a strong internal team and the time to validate the result with your authority.
Where SkyPlannerHub sits
SkyPlannerHub is a cloud ERP/MRO for aviation, so it belongs to the single-platform group. On the maintenance side, it covers AD, SB and life-limited part tracking with due-date alerts, line and base maintenance, shop and overhaul of rotables, aircraft and component history, inventory with traceability by serial number, batch and certificate, and certification management for staff and equipment. On the business side, the same platform includes HR, CRM, planning and finance with e-invoicing.
It does not force a big-bang replacement. Modules are enabled as you need them, and REST APIs, webhooks and connectors link SkyPlannerHub with an existing ERP or third-party systems. Workflows and approval chains are configured for each organisation, and our team builds specific features when a process does not fit. The services page describes the full scope.
Questions to decide
- Which records does your authority audit, and in which system will they live?
- Do you already have a corporate ERP that you must keep?
- How many times is the same data typed today: hours, parts, customer data?
- Who will maintain the integrations, and what happens when one side is upgraded?
- What is the three-year cost of each option, including integration and changes?
Conclusion
MRO software manages the aircraft and the regulated work, an ERP manages the company, and aviation maintenance software is the umbrella over the first. The right architecture depends on your size, your IT and the systems you already have. If you want to review yours, talk to our team and we will show you SkyPlannerHub with your own processes.
