When a custom CRM makes sense

Off-the-shelf CRMs (Salesforce, HubSpot, Bitrix24, amoCRM) fit about 70% of companies — standard funnels, standard reporting, standard accounting. But if your process doesn't fit a boxed model, forcing it into a templated CRM usually ends in broken workarounds you still have to pay for.

A custom CRM is the right call when:

You have a non-standard funnel with 15+ stages and conditional transition logic
You need integrations with 10+ external services that have no ready-made connectors
You need custom calculations: cost price, margin, commissions, bonuses, scoring — things boxed CRMs can't handle
You have 50+ employees and per-seat licensing becomes millions a year
You require on-premise deployment (data must never leave your perimeter)
You need performance on large datasets (hundreds of thousands of deals, tens of millions of records)

What drives cost

Final price depends on several factors. Things to think about when budgeting:

Number of modules and features — from 2 to 20+. Each additional module adds $1,000-$3,000 (₽100K-₽300K)
Business logic complexity — standard funnels are cheaper; custom cost/commission/scoring calculations increase the price
External integrations — accounting, merchant processors, SMS gateways, messengers, email services: +$500-$2,000 (₽50K-₽200K) each
Data migration from existing systems (Excel, Bitrix24, amoCRM, Salesforce) — +$1,000-$5,000 depending on volume and data quality
Roles and permissions — simple "admin-manager" is cheaper than a detailed hierarchy with 10+ roles and fine-grained permissions
Design — template-based vs. custom UI from a Figma mockup with pixel-perfect implementation
Mobile / PWA — separate from web or responsive
Urgency — projects with timelines under 1 month get priority and carry a +30-40% surcharge
Hosting and support — cloud vs on-premise, data volume, SLA 99.5% vs 99.9%

Startups and personal projects get a 15-25% discount off the listed prices.
