When a company outgrows Excel and Telegram threads, boxed CRM is the obvious first step. For typical sales it works. Rental/event gear, long B2B cycles, or tight 1C coupling hit SaaS ceilings fast: custom fields become a zoo, integrations become paid marketplace apps, every new rep adds a monthly seat.
Custom CRM is not «rewrite Bitrix» — it encodes your playbook: deal stages, required fields, automated tasks, director reports, and 1C exchange exactly as your business runs. On Royal Rental and DryRent a deal is a project with gear kits, rigging, quotes, and returns — not a generic funnel.
CRM MVP is usually 15–25 days: brief, pipeline schema, admin UI, roles, priority integrations, staging, training. Vladislav Kompaniec is fullstack — backend, frontend, API, deploy — one contractor. Post-launch changes ship in iterations, not half-year vendor tickets.
On the first call we review team size, current pain, day-one integrations. If SaaS is enough — I'll say so. If custom CRM fits — fixed estimate, timeline, source on your server.
