Our Take
One law firm, one vendor, one model does not prove the market is shifting—but sustained retainer deals are data worth hearing from the people running them.
Why it matters
Legal firms are experimenting with alternatives to billable hours as automation spreads. Practitioners managing vendor relationships or pricing strategy need evidence of what actually sticks beyond the hype cycle.

A 14-year retainer model in production
Alessandro Galtieri, deputy general counsel at Colt, discussed his firm's retainer arrangement with Baker McKenzie at the FT Innovative Lawyers Summit. The engagement has been operational since 2012. The discussion centered on how retainer-based pricing allows law firms to move beyond the billable hour and optimize the deployment of technology within client relationships.
The framing suggests that as firms face pressure to adopt alternative billing models, the retainer structure has proven durable in at least one high-profile case. Galtieri's perspective comes from the vendor side of the relationship, not the law firm side, which shapes what lessons are visible.
Fixed fees require alignment on scope and efficiency
Retainer models succeed when vendor and client agree on what "done" looks like and when automation can reduce time per unit of work. A 14-year engagement signals that both parties found the arrangement sustainable. Neither party has publicized the financial terms, margins, or renewal conditions, so the deeper mechanics remain proprietary.
The legal services market is fragmented by firm size, practice area, and client sophistication. A retainer that works for a global firm like Baker McKenzie may not scale to smaller practices or cost-sensitive sectors. The interview format suggests this is one data point, not a market forecast.
Document your retainer assumptions
If you are managing a legal vendor relationship or designing your own pricing, ask: What specific scope is covered in a retainer? What happens if volume spikes? What automation or process change underpins the fixed fee? Galtieri's 14-year partnership with Baker McKenzie offers proof that the model can outlast a single budget cycle, but it does not reveal which variables matter most to survival. Before committing to fixed fees, map your cost drivers, identify where technology reduces labor, and establish clear renewal criteria. Vendor interviews are useful for credibility; your own numbers are required for safety.
