Combined vs Composio: business-data SQL or agent actions?

Compare Combined and Composio for business-data agents: synced SQL, tool execution, access scope, pricing inputs, and a practical CRM-to-billing evaluation.

By the Combined team · September 10, 2026

Choose Combined when your agent needs repeatable SQL answers across synced business applications. Choose Composio when your product needs agents to discover and execute application tools for users. An agent can use both: Combined supplies the calculation; an action platform performs the authorized follow-up.

Start with the job your agent must finish

“Which customers have open opportunities and recent payments?” and “Create a task for this customer” involve the same applications but different infrastructure. The first needs a defined customer mapping, complete inputs, and a calculation. The second needs the correct account and an application operation. We build Combined for the first workflow: managed ingestion, storage, and query access for the agent you already use.

Combined and Composio — documentation reviewed September 10, 2026
Decision	Combined	Composio
Core workload	Query managed, synced business datasets with SQL.	Discover and execute application tools in a user-scoped session.
Agent interface	Six read-only MCP tools for discovery, SQL, freshness, and text lookup.	Session tools, runtime discovery, and application operations.
Access design	Account scope plus explicit Source grants.	User identity, connected accounts, and toolkit/tool filters.
Coverage to verify	Connection route, selected datasets, fields, and successful sync.	Required tool, its input/output schema, and authentication configuration.
Work your team owns	Source selection, access grants, customer mapping, and metric definitions.	Agent behavior, session configuration, and the desired tool workflow.
Pricing inputs	Monthly active records, including initial ingestion and subsequent activity.	Tool calls, authentication route, triggers, and applicable add-ons.

The Composio column follows its session architecture, configuration guide, and current pricing. These are workload distinctions, not a performance ranking.

What each platform brings to the answer

Composio combines tool discovery, connected accounts, authentication, and execution within a session. Its agent can find a relevant operation while the conversation is running. It also provides a sandbox for processing large responses and bulk work. That is useful infrastructure for an agent that must interact with many services. See how Composio sessions work.

You can narrow a Composio session to particular toolkits or individual tools, select the connected account, and filter for read-only behavior. Configure that surface around your agent's job. See Composio's access configuration.

Combined makes the business records queryable before the question arrives. A single SQL statement can aggregate opportunities and invoices separately, then join their results at the agreed account grain. Your agent discovers the actual schema and reports the last successful sync. You get a managed data layer without separately operating its storage and MCP query service. Combined's 1,125 connectors include desktop-generated connections; check the specific route, readiness, and fields for your apps.

Evaluate the calculation and the follow-up separately

Use a small authorized CRM and billing dataset with two opportunities and two invoices for the same customer. Include an unmatched customer and a second currency. This catches a common failure: joining raw opportunity rows to raw invoices can multiply both totals. Our HubSpot–Stripe example provides an inspectable fixture and query. You can also explore the interactive CRM and billing join lab.

Connect the sources and grant an evaluation agent only those Sources. Discover relations with list_sources, list_datasets, and describe_dataset.
Run the prompt below. Retain the SQL, date bounds, source freshness, unmatched records, and totals. Compare them with the fixture's expected result.
If your product also needs actions, evaluate a separate Composio session with the selected tools. Have it prepare the follow-up fields for one record. Execute a write only in an authorized test account.

Using the granted CRM and billing sources, show open opportunity value
and paid invoice amounts by company and currency for the last 90
complete UTC days. Discover the schema first. Check source freshness.
Aggregate each fact table before joining, and show missing mappings
separately. Return the SQL and a bounded result. Then draft the fields
for one follow-up task. Do not create or send anything.

Score the arithmetic, account identity, completeness, and handoff fields independently. An impressive task-creation demo does not establish the denominator of a revenue calculation; a correct revenue calculation does not establish a write workflow. This exercise tests your implementation of both.

Choose the infrastructure you want to own

Compare a month of expected work: records initially ingested and changed for Combined; executed tools, trigger events, and the applicable authentication and execution options for Composio. Composio's current rate card distinguishes your own credentials from Composio-managed apps. A tool call and an active record are different units, so a price-per-unit comparison alone cannot establish the cheaper stack.

Start with Combined when the deliverable is an answer your team will ask for again: customer context, pipeline analysis, revenue reconciliation, or operational reporting across apps. Start with Composio when tool selection and application execution are the central product experience. Keep both when a calculated business answer needs an authorized action afterward. You can try Combined with an initial 5 million MAR without a card.
