How Long Does Custom Software Development Take? A Realistic Stage-by-Stage Timeline for 2026

An MVP ships in 6–10 weeks (from $10,000). A mid-size project takes 3–6 months ($30,000–100,000), and a large system needs 6–12 months or more. For ERP: a Starter package takes 3–5 months, Standard 5–9 months, Enterprise 9–15 months or longer, measured from business analysis to a working handover.

How long does custom software take by project size?

The answer depends directly on module count and business complexity. The table below is the standard framework FutureTech applies for both the Vietnam and Singapore markets:

Size	Typical scope	Price (USD)	Timeline
Small / MVP	1–3 core modules, one platform, simple flows	From $10,000	6–10 weeks
Mid-size	Multiple modules, API/payment integrations, roles, reporting	$30,000–100,000	3–6 months
Large / Production	Many subsystems, multi-platform, high load, deep integrations	$100,000–350,000+	6–12 months+
ERP Starter (3–5 modules)	Warehouse, purchasing–sales, basic accounting	From $30,000	3–5 months
ERP Standard (6–10 modules)	Plus HR, CRM, production/projects, BI	$50,000–120,000	5–9 months
ERP Enterprise (10+ modules)	Multi-branch, multi-company, deep custom workflows	$120,000–250,000+	9–15 months+

These ranges assume smooth collaboration; in practice many projects add 15–30% because of client-side bottlenecks. For the matching cost breakdown, see how much custom software development costs.

What stages does a software project go through?

A standard project moves through five stages, with coding taking the largest share.

Business analysis (1–3 weeks; 3–6 weeks for ERP)

Analysts work directly with the people who run operations to lock down the requirements document. This is the stage that determines the accuracy of both the quote and the schedule.

UI/UX design and technical architecture (1–4 weeks)

Wireframes and a clickable prototype for your review, alongside database and API design; this stage usually runs partly in parallel with coding.

Coding (50–60% of total project time)

That means 3–6 weeks for an MVP and 2–6 months for mid-size to large systems. FutureTech runs Agile in 1–2 week sprints: you see a demo of working features after every sprint, so business mismatches are caught early. Module count and third-party integrations are the two variables that stretch coding time the most.

Testing and UAT sign-off (15–20% of total project time)

Functional, integration, and load testing, followed by UAT, where your own staff operate the system. For ERP or anything touching money, UAT should run in parallel with the old system through at least one reconciliation cycle.

Deployment and go-live (3–10 days; ERP adds 2–4 weeks of parallel run)

Migrating data from Excel or legacy systems, configuring production, training users, and standing by for post-launch incidents. After handover, the system moves into maintenance at 15–20% of contract value per year.

How long does it take by industry?

Every industry carries a different depth of business logic, so the journey from a Basic package (one core workflow) to an Advanced package (multi-branch, deep customization) varies:

Industry	Basic package	Advanced package
Spa / Aesthetics	5 weeks	5 months
F&B / Restaurants	5 weeks	5 months
Retail / Warehouse (WMS)	6 weeks	6 months
Sales / POS	6 weeks	6 months
Education / Training centers	6 weeks	6 months
Agriculture	6 weeks	6 months
Professional services	7 weeks	6 months
Clinics / Healthcare	7 weeks	7 months
Logistics / Transport	8 weeks	8 months
Construction / Real estate	8 weeks	9 months
Manufacturing / MES	10 weeks	10 months

A Standard package in each industry falls between these two marks, typically 2–4 months depending on integrations.

What drags a project out, and what can you control?

Delivery speed depends substantially on your own company. Three factors you fully control:

• Approval speed: every design or document that sits unreviewed for a week adds exactly one frozen week to the timeline.
• Requirement stability: changing or adding features midway forces rework. Choosing the right software pricing model, Fixed Price for well-defined scope or Time & Material for evolving scope, lets you manage change without breaking the schedule.
• Access and API preparation: providing credentials for legacy systems, accounting APIs, and payment gateways early keeps the development team from sitting idle.

FAQ

I need an MVP urgently for fundraising or a market test. How fast can it go?

The realistic mark is 6–10 weeks from $10,000. The conditions: limit scope to one core revenue-generating flow and approve documents and demos same-day. Lighter industries such as spa or F&B can complete a Basic build in 5 weeks.

Is there a way to get a working ERP faster than 3–5 months?

Yes. FutureTech offers a free foundation ERP (warehouse, sales, basic cash-flow) configured specifically for your business and usable almost immediately; you pay only for additional development when you need specialized modules.

Why does actual delivery often run later than the original commitment?

Because the quoted timeline is built on a preliminary survey. Once deep coding starts, business edge cases and third-party compatibility issues (marketplace APIs, payment gateways) surface and take time to resolve. Budget a 15–30% buffer from the planning stage.

Does a longer timeline increase the cost?

Yes, because project pricing is derived from team rates of $1,500–2,900 per person per month multiplied by duration. Every extra month is an extra month of team cost, which is why fast approvals and stable requirements save you money directly.

Is the timeline different for a Singapore company?

The engineering process is identical. The difference is that Singapore businesses can apply for the EDG grant covering up to 50% of eligible costs, but the project must not start before the application is approved, so grant processing time needs to be added to the overall plan.

FutureTech is a Vietnam-based team that delivers for the Singapore market, working Singapore business hours in English and committing to the timeline it quotes, so the schedule above is a firm plan rather than a hopeful estimate.
