The method

How a CRM integration runs in 4 to 6 weeks

A 6-step method, one deliverable per step. Nothing is improvised.

  1. S11 week
    1 week· Step 1

    We start from the exhaustive list of tools in use (CRM, billing, product, support, marketing) and identify the source of truth for each entity (Contact, Deal, Company, Subscription). We map existing flows and friction points (manual re-entry, known desyncs, duplicates), then design the target state: who is master, who is follower, which webhooks are available.

    • Source of truth per entity
    • Existing flows & frictions

    CRM Integration FAQ

    CRM integration FAQ : Zapier, 2-way sync, API limits, timelines

    Everything to know before starting an integration engagement with Uclic: audit, 2-way sync, event-driven architecture, code and secrets stay with you.

    What is a CRM agency (HubSpot, Pipedrive)?
    A CRM agency, sometimes called a HubSpot agency or integrator, sets up your CRM and connects it to the rest of your tools: website, invoicing, marketing, support. The goal: data that flows on its own, reliable statuses, and teams that never re-enter data by hand. At Uclic, every integration is documented, monitored, and built to survive changes in your tool stack.
    Why not Zapier for these syncs?
    Zapier holds up perfectly as long as you're on 1 to 2 tools, with simple mappings (1 field → 1 field) and low volumes (< 10 000 tasks/month). Beyond that, it breaks for four reasons: (1) no nested objects or complex business logic (validation, conditional branching with state); (2) no 2-way sync with conflict handling: every simultaneous edit creates duplicates or overwrites; (3) no transactions or rollback: an error halfway through leaves your data in an inconsistent state; (4) OAuth tokens are stored on Zapier's side, not yours: you're handing the keys to your CRM over to a SaaS subcontractor. A custom API + webhooks solves all four limitations in a few days and costs less beyond 4 synced tools.
    How do you handle duplicates and conflicts in 2-way sync?
    Four safeguards, in order. (1) Idempotency via event_id: every incoming event carries a unique identifier; already processed = ignored, with a 24h deduplication window in a dedicated table. (2) Business-level deduplication: for contacts, a composite key of normalized email + domain, fuzzy matching on the name, resolution via survivor record before writing. (3) 2-way conflict resolution: if the entity has been modified on both sides since the last sync, an explicit business rule applies: either the most recent wins (timestamps compared), or the priority source of truth overwrites, or a field-by-field merge (HubSpot takes precedence over Email, product over Subscription, etc.). (4) Audit log: every resolution is traced, so you can audit why any given field was overwritten. Without these four safeguards, 2-way sync is a ticking time bomb; with them, it's a predictable system.
    What happens if the HubSpot API rate-limits?
    Three cascading mechanisms. (1) A client-side rate limiter that respects HubSpot limits (100 req/10s on standard), Salesforce (15 000 / 24h Enterprise), or Notion (3 req/s): we don't wait for the error; we prevent it. (2) Exponential retry with jitter on 429 Too Many Requests and 503 Service Unavailable: 1s, 2s, 4s, 8s, 16s, capped at 30s, 5 retries. The jitter prevents thundering herds on recovery. (3) Dead letter queue after N failures: the event is set aside with its payload, alerting is triggered, and it's replayed manually or automatically once the cause is identified. Result: no data lost, no API bans, and your team is alerted before the client even notices.
    Do you host the code, or does the client?
    The code and infrastructure are yours, never Uclic's. The Git repo is created in your GitHub / GitLab organization from day 1. The runtime runs on your cloud: Vercel, Railway, Fly.io, AWS, GCP, Scaleway, OVH, depending on your constraints (sovereignty, compliance, ops team). Secrets (OAuth refresh tokens, API keys) live in your vault: Supabase Vault, Doppler, AWS Secrets Manager, GCP Secret Manager. We can host temporarily during the prototyping phase if you don't have the infrastructure yet, but the handover is completed before going to production. No permanent dependency on Uclic: your in-house team or another provider can take over; the code is documented, the runbook is up to date, and training is done.
    How long does a HubSpot ↔ Notion 2-way sync take?
    For a standard HubSpot ↔ Notion 2-way sync (Contacts + Companies + Deals with 15 to 25 field mappings): 5 business days from kick-off to progressive production rollout. Breakdown: Day 1 system mapping + mapping spec + conflict rules, Day 2 HubSpot + Notion OAuth2 + Inngest / Trigger.dev setup, Day 3 inbound webhooks + event bus + idempotency, Day 4 2-way pipeline + conflict resolution + retry / DLQ, Day 5 load testing (10,000 replayed events), monitoring, runbook, 10% canary rollout to production. Ramp to 50% by Day 7, 100% by Day 10, with a 30-day post-go-live guarantee. For 4 to 6 tools in a full architecture, plan for 4 to 6 weeks.
    Which CRM, productivity and marketing tools do you integrate?
    CRM: HubSpot, Pipedrive, Salesforce, Attio, Folk, Close. Productivity: Notion, Airtable, Coda, ClickUp, Linear. Communication: Slack, Discord, Microsoft Teams, Twilio. Payments / invoicing: Stripe, Lago, Paddle, Chargebee. Marketing automation: Brevo, Lemlist, Customer.io, Loops. Auth: Clerk, Auth.js, Supabase Auth. Code stack: Python (FastAPI, requests-oauthlib), TypeScript (Hono, OAuth4WebApi, Next.js routes), Inngest and Trigger.dev for event-driven orchestration, Postgres / Supabase as the canonical hub. If a tool isn't on this list but exposes a REST API or webhooks, we can integrate it: the work is in the mapping and business rules, not in the connector itself.
    How much does a CRM integration cost?
    Three price ranges depending on scope. 1-tool ↔ CRM sync (HubSpot ↔ Stripe for example): quote-based, 5 to 10 days of production work, delivered in 2 to 3 weeks. 3-4 tool stack (CRM + invoicing + product + marketing): quote-based, 15 to 25 days of production work, delivered in 4 to 6 weeks. Full 6+ tool stack with data warehouse: quote-based, 30 to 60 days of production work, delivered in 8 to 12 weeks. We price based on a Week 1 scoping (mapping + flows), not on a ballpark guess. You keep 100% of the code and infrastructure: no hidden Zapier-style subscription that balloons with volume.
