People still pay for Bigin because CRM value compounds as the system becomes the shared memory of every customer interaction and embeds itself in the rest of the stack. The recurring cost buys deduplication, permissions, imports, sync, enrichment, email capture, automations, backups, and audit history, not just the visible interface.

what AI can build
Manage contacts and companies for a small business, move opportunities through a pipeline with simple workflows, log interactions and activities, and surface the next action.
The core loop is buildable, but a dependable replacement becomes a real weekend or multi-day project. For Bigin, run a small-business pipeline with contacts, activities, and simple workflows. The hard boundary is zoho ecosystem, telephony, forms, integrations, and mobile apps, plus integrations, data quality, and workflow lock-in.

the prompt
Catalog estimateBuild a personal replacement for Bigin in an empty repository. Use Next.js 15, TypeScript, PostgreSQL, Drizzle ORM, and Docker Compose; do not offer alternative stacks. The core loop is: manage contacts and companies for a small business, move opportunities through a pipeline with simple workflows, log interactions and activities, and surface the next action. Make the first run work locally with one documented command. Store all user data locally by default and make export straightforward. Put secrets in .env, ship .env.example, and never commit credentials. Create contacts, companies, opportunities, notes, tasks, and configurable pipeline stages. Add fast global search, duplicate detection, merge, CSV import, and CSV export. Provide a chronological interaction timeline with manual email and meeting logging. Implement saved views, filters, owner assignment, and a next-action dashboard. Add role-based access, an immutable activity log, backups, and a recovery command. Seed a realistic demo workspace and document field mapping for imports. Include clear empty, loading, success, and recoverable error states. Add input validation, safe filenames, and graceful handling of unavailable APIs. Write focused tests for the core transformation and one end-to-end happy path. Create a README with setup, architecture, permissions, data location, and backup steps. Do not add accounts, billing, telemetry, analytics, or a hosted control plane. Deliberately leave out automatic mailbox ingestion. Deliberately leave out commercial enrichment databases. Deliberately leave out enterprise forecasting, integrations, and compliance. Finish by running the tests and listing the exact commands used.

questions
Can AI replace Bigin?
Possibly for a narrower core workflow, but this catalog judgment is not a verified build. Expected gaps include: Zoho ecosystem, telephony, forms, integrations, and mobile apps, automatic email and calendar capture. Validate the prompt against your own acceptance criteria before committing.
How much does Bigin cost?
Bigin is listed at about $9/month (Express, checked 2026-07-31), or $108 per year. This is a pricing reference, not evidence of a completed replacement or realized savings.
What do I lose by replacing Bigin?
Honestly: Zoho ecosystem, telephony, forms, integrations, and mobile apps; automatic email and calendar capture; data enrichment; large integration ecosystem; enterprise reporting. If any of those are load-bearing for you, keep paying.
Is there an open-source alternative to Bigin?
Yes — Twenty (Active open-source modern CRM with extensible data models.). Using prior art is also a valid exit; the prompt is for when you want it exactly your way.
