Most IoT products take about 3 to 6 months to go from idea to a working, field-ready system: a 2–4 week proof of concept, a 4–8 week pilot, then hardening and rollout. Simple sensor-to-dashboard projects can be quicker; products that need a custom PCB, certification or a large device fleet take longer.
TechieYan Technologies is an IoT product development company in Hyderabad that has delivered 200+ deep-tech projects since 2018. Here is what actually drives the timeline, so you can plan realistically.
The short answer: a typical IoT timeline
- Discovery & proposal: a few days
- Proof of concept (PoC): 2–4 weeks
- Pilot on one site, line or fleet: 4–8 weeks
- Hardening, OTA & rollout: 4–12 weeks, depending on scale and certification
For a software-only or off-the-shelf-hardware project you may skip straight from PoC to rollout. For a product with custom electronics, add time for PCB spins and (if needed) CE/FCC/BIS pre-compliance.
Phase 1 — Discovery (a few days)
A short call and a written scope: what you want to measure or control, where devices are installed, connectivity, and how success is measured. You should leave this phase with a fixed-scope proposal, a rough bill of materials and clear milestones — not an open-ended estimate.
Phase 2 — Proof of concept (2–4 weeks)
A working sensors-to-dashboard demo on your bench or site, so you see real data before committing more budget. This is where connectivity choices (Wi-Fi, LoRaWAN, BLE, 4G/NB-IoT) and PLC integration (Modbus, OPC UA) are proven. If a custom board is required, the first PCB design and bring-up often overlaps this phase.
Phase 3 — Pilot (4–8 weeks)
Hardened devices, a gateway and cloud running on one line, site or fleet, with weekly demos. Firmware is stabilised, embedded updates and over-the-air (OTA) delivery are added, and dashboards get alerts and user roles.
Phase 4 — Hardening & rollout
Production-ready design files, documentation, training and scale-up. Timeline here depends on how many devices you deploy and whether the product needs formal certification before sale.
What makes an IoT project faster or slower
- Custom hardware vs off-the-shelf: a custom PCB adds fabrication and bring-up spins; off-the-shelf modules are faster but less optimised.
- Connectivity & site conditions: reliable Wi-Fi is quick; large farms or plants on LoRaWAN, or vehicles on 4G, need more field testing.
- Integration: connecting to existing machines, PLCs or ERP/MES adds scope.
- Certification: CE, FCC or BIS pre-compliance adds weeks but is planned up front.
- Fleet size: ten devices roll out faster than ten thousand.
How to keep an IoT timeline predictable
The projects that slip are usually the ones that skipped a proof of concept. Starting with a scoped 2–4 week PoC removes the biggest unknowns early, so the pilot and rollout run to plan. See real examples on our projects page, including an AgriTech sensing network and shop-floor predictive maintenance.

Frequently asked questions
How long does it take to build an IoT product?
Most IoT products take 3 to 6 months end to end: a 2–4 week proof of concept, a 4–8 week pilot, then hardening and rollout. The exact timeline is fixed in the proposal before work starts.
Can you build just a proof of concept first?
Yes, and we recommend it. A scoped 2–4 week PoC shows real data on a dashboard and gives you a go/no-go decision before larger spend.
Does a custom PCB make it take longer?
It adds time for fabrication and one or two bring-up spins, but it produces a smaller, cheaper, more reliable product. Off-the-shelf modules are faster when optimisation is not critical.
What slows an IoT project down the most?
Unreliable connectivity at the site, deep integration with legacy machines, and certification. All three are identified in discovery so the timeline accounts for them.
Do you work with companies outside Hyderabad?
Yes. We work with clients in Bengaluru, Pune, Chennai, Mumbai, Delhi NCR and abroad, remotely with on-site visits for installation and commissioning.
