Stripe → Attio: the CRM finally knows what each account is worth

Every B2B company hits the same wall: revenue lives in Stripe, and the CRM has a "MRR" field someone updated in February. Decisions get made on stale data. Expansion conversations happen without anyone checking whether the customer actually paid their last invoice. We close that gap. Subscriptions, MRR, last payment, failed-payment state, trial status, and invoice history all land in Attio and stay there. Your CSMs and AEs finally operate on the same numbers as finance, without a BI layer in between.

The what

What this integration actually does

It writes Stripe truth directly onto the Company record in Attio: live MRR, contract value, renewal date, last invoice status, failed payment flag, plan. When a payment fails, the CSM knows before the customer emails. When a subscription upgrades, the AE sees the expansion without anyone logging it.

The how

How we build it

  1. 1

    Map Stripe customers to Attio Companies - by domain when clean, by Stripe customer ID as the canonical reference.

  2. 2

    Wire the six webhooks that matter: customer.subscription.{created,updated,deleted}, invoice.{paid,payment_failed}, charge.refunded.

  3. 3

    Normalize in n8n - Stripe data is verbose and multi-currency; Attio wants a clean MRR in the reporting currency you chose.

  4. 4

    Backfill historical state with a one-time sync so day-one data isn't a cliff.

  5. 5

    Build the Slack alerts your finance team would actually read - not every event, just failed payments on accounts above a threshold.

Under the hood

What lives inside the pipeline

  • Read-only by default - we never write to Stripe without a confirmation step. Billing data is real money.
  • Multi-currency normalization to your reporting currency (live FX or fixed rate, your call).
  • Trial-to-paid flip that triggers a Slack ping and updates the Company stage.
  • Dunning state mirrored as a field so CSMs don't call customers whose card is already failing.
  • Churn detection - cancelled subscription triggers a churn investigation record in Attio.

Hard-earned lessons

What we learned the hard way

  • Stripe's invoice.paid and charge.succeeded overlap. Pick one as the signal for "they paid" or you'll double-count.
  • Proration events are messy. Budget time to decide whether mid-period upgrades bump MRR immediately or at the next billing.
  • Never run anything destructive against a production Stripe key without read-only mode and explicit confirmation. Always.
  • Customer metadata is the right place to store the Attio Company ID - not the Stripe description field.

Case study

MAAT - gym SaaS

Problem

MRR lived in Stripe. The CRM had a MRR field that was manually updated monthly, always out of date. No one trusted the numbers.

Solution

Full Stripe → Attio sync went live end of March after a read-only validation phase. All subscriptions, invoices, failed payments mirrored in real time.

Outcome

The commercial team now operates on live revenue data. The manual update job is gone. QBR prep dropped from half a day to minutes.

FAQ

Questions we get

Yes, and we treat it that way. We start in read-only mode, validate on real data for a week, and only enable any write-back (rare) with explicit confirmation. Stripe is real money - we're cautious by default.

Yes. We run a one-time backfill so day one in Attio has full billing history, not just the future.

Out of scope by default - they change often and rarely add signal. We can add them if your sales process uses Stripe Quotes.
