Build it yourself
Signals vs a DIY data warehouse
You can absolutely build a customer timeline yourself: pipe Stripe, Gmail, and your CRM into a warehouse with Fivetran, model it in dbt, and put Metabase on top. This page is an honest accounting of what that costs in money, time, and upkeep — compared to connecting the same tools to Signals.
The short version
If you have a data team and questions unique to your business, a warehouse is the right long-term asset — nothing beats owning your own models. If what you actually want is to know who needs a reply and who is quietly churning, a warehouse is a multi-week detour: Signals answers those questions out of the box for less than the cheapest line item in the DIY stack.

Where the warehouse route shines
A warehouse is the most flexible tool that exists for customer data. Once Stripe, email metadata, and CRM records land in Snowflake, you can join them against product usage, finance data, or anything else, and answer questions no packaged product anticipated. If you already employ a data engineer and your questions are genuinely bespoke — cohort economics, custom attribution, board-level revenue modelling — build the warehouse. It compounds: every model you write makes the next question cheaper to answer.
The stack is also better than it has ever been. Fivetran connectors are reliable, dbt makes the modelling maintainable, and Metabase or Looker Studio put a decent query UI on top. None of this is the hard part anymore.
What it actually costs
The tooling is the small line item. Fivetran, a modest Snowflake account, and a hosted BI tool land around $250–$900 a month for a small B2B dataset — an estimate built from each vendor's public pricing mechanics as of July 2026, since none of the three publishes a fixed "small company" price — but the real spend is people: someone has to design the schema that joins a Stripe customer to an email thread to a CRM deal, keep the syncs healthy, and maintain the dashboards. That is roughly 2–4 person-weeks of engineering up front and a recurring tax after — every time Stripe changes a field or someone renames a CRM stage, a dashboard quietly breaks.
Signals is $29/mo (Starter) or $99/mo (Growth). The identity-resolution problem — is [email protected] in Stripe the same person as the [email protected] thread in your inbox? — is already solved in the product.
The question you are actually trying to answer
Most teams reaching for the warehouse are not trying to do analytics. They are trying to answer three operational questions: who needs a reply, who is at risk of churning, and what happened with this customer lately. Those are lookups against a unified timeline, not analyses — and a BI dashboard is a clumsy way to serve them, because dashboards aggregate while these questions need per-customer detail with the full event history behind it.
Signals is built around exactly that timeline. Connect Stripe, Gmail, Google Calendar, and your CRM; history backfills automatically; and the product answers those three questions on day one, no SQL involved.
A reasonable middle path
This is not either/or. Plenty of teams run Signals for the operational layer — the daily "who needs attention" workflow — and build the warehouse later, when a real data hire arrives and the bespoke questions have piled up. Starting with Signals costs $29 a month and ten minutes; starting with the warehouse costs 2–4 weeks before the first useful answer. If the warehouse is in your future anyway, deferring it until you have the team to own it is usually the cheaper sequencing.
Switching to Signals
There is nothing to migrate. Signals connects to Stripe, Gmail, Google Calendar, and OnePageCRM with read-only access, backfills your history automatically, and starts answering questions in minutes. If you later build a warehouse, nothing about Signals is in the way — your data stays in your tools; Signals just reads it.
