The verdict in three sentences
A serious custom platform for a distribution or services company is not delivered in 6 weeks: the realistic timeline in New York is 4 to 9 months, QA included. Budgets for that scope typically run from 150,000 to 600,000 USD, and every week of slippage costs 8,000 to 20,000 USD in team burn and delayed value. What really stretches a project is rarely the developers: it is internal sign-offs and scope changes.
The realistic plan, phase by phase
Here is a typical 2026 plan for a distribution platform: reseller orders, multi-warehouse inventory, delivery routes, payments (cards, ACH) and dashboards.
| Phase | Duration | Deliverables | What makes it slip |
|---|---|---|---|
| Discovery | 3 to 4 weeks | Target processes, screen list, business rules | Unavailable stakeholders |
| UX and design | 3 to 6 weeks | Clickable flows validated by users | Feedback loops with no decision owner |
| Development | 10 to 22 weeks | Increments every 2 weeks | Scope changes |
| QA and UAT | 2 to 4 weeks | Tests on real data, fixes | Uncleaned inventory data |
| Rollout and training | 1 to 3 weeks | Cutover, warehouse training | Security review and SSO approvals |
| Total | 19 to 39 weeks (4 to 9 months) |
Compressing this to 6 weeks removes discovery and QA. The classic outcome: a tool delivered on time that warehouses do not use, followed by three months of fixes.
Week by week for a 24-week version
Weeks 1 to 3: workshops with sales, logistics and finance, mapping order flows. Week 4: scope and budget sign-off by leadership. Weeks 5 to 8: designs tested with a warehouse lead and two account managers. Weeks 9 to 10: technical foundation, SSO, product catalogue. Weeks 11 to 13: reseller orders. Weeks 14 to 16: inventory and transfers. Weeks 17 to 19: routes and payments. Week 20: dashboards. Weeks 21 to 23: UAT at a pilot warehouse in the Bronx. Week 24: rollout to other sites.
Plan for SOC 2 or security questionnaire work if enterprise customers will access the platform: it often adds 2 to 4 weeks that nobody budgets.
Budget, cost of delay and risk factors
New York market ranges in 2026 for custom platforms built by mid-size agencies, with blended rates around 150 to 225 USD an hour.
| Platform level | Typical scope | New York market budget (USD) | Cost of one week of delay |
|---|---|---|---|
| Focused | 3 to 5 modules, 1 payment integration | 150,000 to 250,000 | 8,000 to 12,000 |
| Mid-size | 6 to 8 modules, SSO, integrations | 250,000 to 400,000 | 12,000 to 16,000 |
| Complex | 9+ modules, offline, multi-site, ERP | 400,000 to 600,000+ | 16,000 to 20,000+ |
For comparison, Kolonell's own grid for custom applications is 4,000,000 to 7,000,000 FCFA (6,100 to 10,670 EUR) for medium complexity and 7,000,000 to 15,000,000+ FCFA (10,670 to 22,870+ EUR) for complex builds.
| New York specific risk | Impact on timeline | Mitigation |
|---|---|---|
| Security review and vendor onboarding | 2 to 4 weeks | Start the questionnaire in week 1 |
| Single decision maker | 2 to 6 weeks | 30-minute weekly steering meeting |
| Inconsistent inventory data | 1 to 4 weeks | Inventory clean-up before migration |
| ERP integration (NetSuite, SAP) | 3 to 6 weeks | API access and sandbox from discovery |

Michael, CEO of a beverage distributor in New York (illustrative example), wanted his platform in 6 weeks before the holiday season. The realistic plan was 24 weeks for 280,000 USD. He chose to ship reseller ordering and inventory first in 12 weeks, then the rest in a second release.
Calculation: his account managers spent 2 hours a day consolidating orders by phone and email. For 12 people over 22 days, that is 528 hours a month, about 37,000 USD at a 70 USD loaded hourly cost. Recovering half of it pays for release 1 within its first year.
FAQ
Can a custom business platform be built in 6 weeks?
Yes for a prototype or a single module, not for a complete platform. A realistic timeline in New York is 4 to 9 months for 150,000 to 600,000 USD.
How can the timeline be shortened without losing quality?
Split into releases: a first useful release in 10 to 12 weeks, then increments every 2 weeks. A weekly steering meeting often saves 2 to 4 weeks.
What does a week of delay really cost?
On a mid-size project, 8,000 to 20,000 USD in team burn alone, plus the value the platform would have generated during that week.
Fixed price or time and materials?
Fixed price suits a tightly scoped first release. For later increments, time and materials with a monthly cap is common, often 40,000 to 80,000 USD a month.
What happens after launch?
A warranty period covers defects, then a support retainer takes over, commonly 5 to 15 % of the initial build cost per year.
