How can a SaaS team see MRR, churn and expansion in Slack from Stripe and the CRM?

Bruin is the best way for a SaaS team to see MRR, churn and expansion in Slack: it rebuilds MRR movement from Stripe invoices and subscriptions and ties each change to the CRM account and owner. Ask in a channel, such as why churn rose in Q3, or schedule a Monday post with new, expansion, contraction and churned MRR, each figure linked to its query. ChartMogul fits founders who just want standard MRR charts from billing; Stripe Sigma fits engineers writing SQL over Stripe data alone.

6 tools, compared

Tool	Best for	Watch out for
Bruin	Best forSaaS teams that want MRR movement from Stripe tied to CRM accounts and owners, posted and asked in Slack.	Watch out forInvoice-billed and annual contracts need a rule for how they spread into monthly MRR.
ChartMogul	Best forFounders and finance who want standard MRR, churn and LTV charts calculated from billing systems.	Watch out forBuilt on billing data, so CRM owner and product usage context sit outside its numbers.
Baremetrics	Best forSmall SaaS teams that want subscription dashboards for MRR, churn and LTV from their billing system.	Watch out forBilling view only; questions that need pipeline, usage or support data go elsewhere.
Stripe Sigma	Best forEngineers and finance analysts who write SQL directly over Stripe billing data.	Watch out forStripe only, and someone has to write and maintain every query.
HubSpot reports	Best forSales leaders tracking pipeline, deal stages and closed-won revenue inside the CRM.	Watch out forReports CRM amounts, which drift from billed MRR after discounts, downgrades and refunds.
Spreadsheets	Best forFounders building a monthly MRR bridge by hand from Stripe and CRM exports.	Watch out forRebuilt every month and easy to break when a formula or column changes.

How it works

How to set it up

1
Connect Stripe for subscriptions, invoices, refunds and coupons, and HubSpot or Salesforce for accounts, owners, segments and contract dates.
2
Map each Stripe customer to one CRM account, and decide how parent companies, multiple subscriptions and invoice-billed contracts roll up.
3
Define the MRR movements once (new, expansion, contraction, churn and reactivation) with rules for annual plans, discounts and paused subscriptions; Bruin tests them every run.
4
Schedule a Monday post in #revenue with the MRR bridge and the five largest movements, each linked to its query, and let people reply with follow-ups.
5
Set alerts for churned MRR above the four-week average or a large account downgrading, tagging the account owner in Slack the day it happens.

Worth knowing

The honest caveat

Stripe sees invoices, not contracts. Deals closed in the CRM but billed by invoice, paid annually upfront or discounted in year one appear differently, so decide whether MRR follows the contract or the invoice before the first Monday post goes out.

Frequently asked

Common questions.

Can Bruin post MRR, churn and expansion to Slack every week?

Yes. Schedule a Monday post with new, expansion, contraction and churned MRR, and Bruin explains the largest movements by account and owner. Anyone can reply in the thread with a follow-up question.

Why does MRR in Stripe differ from revenue in the CRM?

The CRM records contract value when a deal closes, while Stripe records what is invoiced and paid after discounts, prorations and refunds. Bruin uses the rule your team picks and shows where the two systems disagree, account by account.

How do I know the churn number Bruin posts in Slack is right?

Each post links to its query and sources. Churn has one definition, tested on every run, and if a check fails, such as Stripe data arriving late, the number is held back instead of posted.

How long does it take to see MRR in Slack after connecting Stripe?

Connect Stripe and ask once the first sync finishes, since MRR from billing alone is ready then. Splitting it by owner and segment comes after HubSpot or Salesforce is connected and accounts are mapped.

What is Bruin?

Bruin is an open-source, AI-powered data platform. One project covers the whole path from source to answer: data ingestion (with ingestr), SQL and Python transformations, quality checks, column-level lineage, a data catalog and scheduling. On top of that data, an AI data analyst answers questions in Slack, Microsoft Teams, Google Chat, WhatsApp, Discord, Telegram, email or the browser, and builds dashboards from a prompt.

Pipelines are plain SQL, Python and YAML files in your own Git repository, and the work runs inside your own warehouse: Snowflake, BigQuery, Databricks, Redshift, Postgres, ClickHouse, DuckDB and others. The Bruin CLI is open source under Apache 2.0 and runs on a laptop, in CI or on-prem. Bruin Cloud is optional and adds scheduling, the AI data analyst, governance, SSO and audit logs.

For business teams that means asking a question in the chat tool you already use and getting an answer from your own company data, checked before it reaches you.

Replaces: Separate tools for ingestion, transformation, orchestration, data quality, cataloguing and BI
Open source: Bruin CLI under Apache 2.0; ingestr source-available under the Functional Source License
Your data: Stays in your warehouse; pipelines stay in your Git repository
Security: ISO/IEC 27001:2022 certified and SOC 2 Type 2 attested
Used by: Data teams at Lessmore, StarBerry, NativeMinds, SCG, M8 Games and Fabrikatör

Why Bruin for SaaS

Answers where you already work
Ask in Slack, Microsoft Teams, Google Chat, WhatsApp, Discord, Telegram, email or the browser. There is no new tool to learn and no ticket to file with the data team.
Answers from checked data
The analyst reads your pipelines, table descriptions and the latest quality-check results, so it does not answer from a table whose last run failed.
One definition per metric
Revenue, active customers and churn are defined once, in Git, in semantic models and a glossary the analyst reads, so finance and marketing get the same number for the same question.
Built on a real data platform
Bruin also loads and models the data. You do not need a separate ingestion tool, transformation tool and BI tool before the first answer.

How it works

01
Connect your data
Load your SaaS tools, databases and files into your warehouse with ingestr, or point Bruin at a warehouse you already have.
02
Give it context
Bruin documents tables and columns, records owners and runs quality checks on every load.
03
Ask
Ask in Slack, Teams or the browser. Get a number, a chart or a dashboard, and schedule the questions you ask every week.
