The verdict in three sentences
A custom business web app in Miami ships in 2026 in 4 to 6 months for a standard scope. The calendar breaks into scoping (3-4 wks), development (8-16 wks) and QA (3-4 wks), each phase liable to slip if the previous one was rushed. The associated budget runs from USD 60,000 to USD 180,000 depending on modules and integrations.
The timeline phase by phase
The timeline isn't just about coding speed: half the schedule happens before and after development.
| Phase | Duration | What happens | Risk if rushed |
|---|---|---|---|
| Scoping | 3-4 wks | Specs, journeys, backlog, mockups | +30 % dev delay |
| Development | 8-16 wks | Front, back, API, integrations | Technical debt |
| QA / UAT | 3-4 wks | Tests, fixes, acceptance | Production bugs |
| Deployment | 1-2 wks | Go-live, training | Low adoption |
A 2-3 module scope fits within 4-5 months; beyond 5 modules or with heavy integrations (ERP, payment, EDI), you move to 6-8 months.
The impact of a vague spec
The leading cause of delay isn't technical: it's a poorly defined need. Here is the measured effect on a 20-week reference project.
| Scoping quality | Actual timeline | Overrun | Main cause |
|---|---|---|---|
| Precise specs + mockups | 20 wks | 0 % | Baseline |
| Partial specs | 24 wks | +18 % | Back-and-forth |
| Vague spec | 26 wks | +30 % | Mid-build rework |
| Moving scope | 30+ wks | +45 % | Constant scope creep |
Investing 3-4 weeks of serious scoping (5-8 % of budget) is the best lever on timeline: every day of specs saves several days of redone development.

Mini case study
Karim runs a distribution SME in Miami and wants to digitize supplier orders. Scope: 3 modules (catalog, orders, delivery tracking). Budget USD 72,000, target timeline 5 months.
By giving scoping to a nearshore team and validating mockups before development, he delivers in exactly 5 months instead of the 6.5 months a vague start would have cost (overrun avoided ~USD 13,000). Operational gain: his buyers save 10 hrs/week of phone follow-up, about 520 hrs/year per buyer.
FAQ
Can you go faster than 4 months? Yes for a 1-module MVP (6-10 weeks), but a full business scope rarely compresses under 4 months without sacrificing QA.
What does a nearshore team bring? A 2026 nearshore day rate of USD 250-450 (vs USD 700-1,000 for an equivalent US profile) buys more person-days at equal budget, often with overlapping working hours.
How do you avoid overruns? Written scoping, validated mockups, 2-week sprints with demos, and a prioritized backlog frozen mid-sprint.
Can QA be shortened? It's risky: cutting QA pushes bugs into production, where they cost 5 to 10 times more to fix.
Should everything ship at once? No. Module-by-module deployment enables progressive adoption and earlier user feedback.
