Is fixed-fee delivery really possible for complex software projects?

For projects scoped through our discovery process, yes. The discovery phase is specifically designed to understand complexity before fixing the price. For projects where scope is genuinely too fluid to fix, we recommend starting with a discovery sprint to create that clarity.

What happens if requirements change mid-project?

Changes are identified at milestone review points. If a change expands scope, we price it transparently before proceeding. We do not build unauthorised scope and invoice for it later.

Can we start with just a discovery engagement?

Yes. This is the most common starting point for new clients. The discovery produces a deliverable — an implementation roadmap — that has value independent of whether you proceed with Techseria for implementation.

What is the typical cost of a fixed-fee discovery?

Discovery engagements are priced based on scope complexity. We discuss this on the initial strategy call. The discovery is designed to be a proportionate investment relative to the implementation it informs.

Most software vendors sell time. Billable hours, monthly developer retainers, or time-and-materials contracts that give buyers no certainty of cost or outcome. When the project takes longer than expected — as most do — the buyer absorbs the overrun. Techseria structures every engagement around outcomes, not hours.

Why commercial model clarity matters for you

Open-ended billing creates a structural misalignment: the vendor benefits from scope growth, and the buyer bears the risk. Fixed-fee, milestone-based delivery reverses that. When the scope and cost are agreed before work begins, both parties have the same incentive — to deliver the agreed outcome efficiently.

The four phases of a Techseria engagement

Fixed-Fee Discovery: Every engagement starts here. We review your current situation, define the business outcome, assess scope and complexity, and produce a clear implementation roadmap. This phase is time-boxed (typically 4–6 weeks) and priced at a defined fixed fee. You pay a specific amount. You receive a specific deliverable: a scoped implementation plan with cost estimate. You are not committing to anything beyond discovery at this stage.

Fixed-Fee Implementation Sprints: Implementation is structured in time-boxed sprints — typically 4–8 weeks each. Each sprint has a defined scope, a fixed cost, and a specific deliverable agreed in writing before the sprint begins. You review the output before the next sprint starts. There are no surprise invoices at the end of a long development cycle.

Milestone Accountability Checkpoints: Each milestone represents a defined, reviewable output. Milestones create natural decision points: proceed, adjust, or stop. You are never locked into a trajectory that is not delivering the expected result. If new complexity emerges, we flag it before absorbing it.

Optional Managed Optimization Retainer: After implementation, you may want ongoing support, system evolution, or continuous improvement. Techseria offers a managed optimization retainer for this purpose. This is optional — not a mandatory lock-in. Many clients operate their delivered systems independently after handover.
