Timelines depend entirely on scope, and are agreed in the proposal stage — before development begins — so you have a delivery date rather than an open commitment.
What drives the timeline
- Scope — a focused tool versus a full platform
- Integrations — each external system adds work, and third-party dependencies are the most common cause of slippage
- Scale requirements — systems built for very high request volumes need more architectural work
- Clarity of requirements — the single biggest factor within your control
How to keep it short
- Define must-have versus nice-to-have before scoping, and be honest about which is which.
- Phase it. A working first version delivered early, extended afterwards, almost always beats a complete system delivered late.
- Nominate one decision-maker. Projects stall on unresolved internal disagreement more often than on engineering.
A faster alternative worth considering: if a large part of what you need already exists, DSP Acquisition gives you a working platform with source code in 5–7 business days, which you then extend. Building from scratch when 80% exists is rarely the efficient path. See DSP License vs DSP Acquisition.
