Maintenance and support is the recurring fee that funds updates and assistance on licensed software, and the back charge for unpaid periods is what inflates many audit settlements in a deal.
What is maintenance and support? Maintenance and support is the recurring annual fee that entitles a licensee to software updates, patches, new versions and technical assistance. It usually runs at a fixed percentage of the license list price and renews each year. In M&A this matters because maintenance is both a large recurring cost and a hidden audit multiplier. When a publisher finds unlicensed use, it does not only charge for the missing licenses, it adds back maintenance for the period of non compliance, which can double the settlement.
Maintenance and support looks like a predictable line item until an audit changes it. A publisher that discovers a shortfall prices the missing licenses at list, then adds the maintenance that would have been owed on those licenses for every year of overuse. A three year breach can therefore carry three years of back maintenance on top of the license cost. This back charge is the part of an audit settlement buyers most often overlook when they estimate the cost to cure.
Maintenance also drives the run rate of the combined estate. It compounds, because it is charged on the cumulative license base and rises with each true up. Reinstating lapsed maintenance is usually penalised, so a target that dropped support to save money may face reinstatement fees and back maintenance to return to a supported position. Oracle and SAP both apply policies that make lapsing and reinstating maintenance expensive, which a buyer needs to model before assuming a saving.
In a deal the maintenance exposure is latent in two ways. The back maintenance attached to any non compliance does not appear until an audit, and the forward maintenance obligations on the combined estate are easy to understate when two support contracts merge. Quantifying both, the back charge risk and the forward run rate, gives the buyer a complete picture. Maintenance negotiation is commercial and licensing advisory, not legal advice.
Back maintenance is a core component of the cost to cure, the full price of returning a non compliant estate to compliance. A defensible cost to cure prices the license shortfall and then adds the back maintenance owed across the non compliant period, which is where a settlement quietly grows. Presenting maintenance separately, rather than folding it into a single license figure, helps the deal team see how much of an opening demand is back charge that can be negotiated.
| Aspect | What it covers | Deal impact |
|---|---|---|
| Annual fee | Updates, patches, support | Large recurring run rate cost |
| Back maintenance | Support owed during overuse | Inflates audit settlements |
| Reinstatement | Returning lapsed support | Penalties and back fees apply |
| Merged contracts | Two support bases combined | Forward cost easy to understate |
