AI integration services for the systems you already run

Signa’s AI integration services connect AI agents and workflow automation to the systems your business already runs: CRM, accounting, ERP, inboxes, spreadsheets and older systems with no API. Nothing gets replaced. Agents start by reading, a person approves every write until it is proven, and everything is logged.

What we connect

Systems by kind. If it holds the work, there is usually a way in.

CRM
Contacts, deals and activity, so an agent sees the customer’s history before it drafts or routes anything.
Accounting and billing
Invoices, payments and customer records, matched across systems so a mismatch is flagged instead of buried.
ERP and inventory
Orders, stock and shipments, including on-premise systems installed long before AI.
Inboxes and email
The requests, orders and confirmations that arrive by email, read and turned into clean records.
Spreadsheets
The schedule, price list or account sheet the operation depends on, treated as a system of record.
Older systems with no API
Through a read-only database view, scheduled exports, the emails the system already sends, or screen-level automation as a last resort.

How we connect safely

Read first. Earn write access one action at a time.

The most stable way in
A supported API first. Then a read-only database view, scheduled file exports or email. Screen-level automation only when nothing else works.
Read-only first
The first release reads from your systems and prepares work for a person, so you see how accurate it is without risking your records.
Its own account, fewest permissions
The agent gets its own service account, never a shared admin login or a person’s credentials, and reaches only what its job needs.
A person approves writes
Write access comes one action at a time, with approval at first. Each step is reversible and tested on real cases.
Every action in an audit log
What the agent did, to which record, when, from which input and who approved it. When someone asks why an order changed, one lookup answers.
Checks for quiet failures
Alerts when data is stale, a unique key on every write so a retry cannot duplicate a record, and a daily check that what the agent did matches what your system shows.

What a production change actually involved

Moving a sales agent to a new production runtime involved more than choosing the runtime. We verified the connection to the team’s work surface, preserved pending workflow state, checked approval ownership and duplicate controls, tested restart behavior, and restored a backup into an isolated location to prove recovery.

The old runtime stayed available as a rollback while the new release was observed. No test message reached a customer. These are documented delivery tasks, not estimates of the client’s costs.

They show why model usage is a poor proxy for the price of a dependable system. Integration, state, testing, recovery, and continued care are real work even when the visible result is a short conversation.

From our article What an AI agent really costs.

What stays yours

Your systems
Nothing is replaced. Replacing a tool is only worth it when it blocks the work.
Your accounts
The integration, the agents and their credentials run in your accounts, not ours.
Your records
Your systems stay the record. The agent reads what it needs and writes only what has been approved.
The documentation
What connects to what, how, with which permissions, and how to change or switch it off.

How AI integration works

One connection at a time, starting with the one the slowest work depends on.

Embed
An engineer maps the work and the systems it touches, with whoever administers them today.
Build
We connect through the most stable way in, read-only first, for the slowest step.
Train
Your team learns to read the log, approve writes and spot a connection that has stopped.
Hand over
It runs in your accounts, documented, with failures flagged to a named person. Then the next connection.

Who it is for and what it costs

Who it is for
Owners and operators of businesses past $10 million a year, where growth has meant more hires, more handoffs and more of your own time holding it together.
What it costs
Engagements start at $10,000 per month, one priority at a time on a weekly loop.
What you own
Everything we build. It runs in your accounts, with documentation your team can follow and change.

Questions about AI integration services

What are AI integration services?

Connecting AI agents and automation to the systems a business already runs, so they can read the work and act on it. Signa does it inside your business, read-only first, with a person approving writes and every action logged.

Can you connect AI to a system with no API?

Usually, yes. A read-only database view, scheduled exports or the emails the system already sends are common ways in. Screen-level automation works when nothing else does, for a narrow set of steps.

Do we have to replace our software?

No. We connect the systems you already run. A replacement is only worth it when a tool blocks the work.

How do you stop an agent changing the wrong record?

It starts read-only. Write access comes one action at a time with a person approving, every write has a unique key so a retry cannot duplicate it, and every action is in an audit log.

Is AI integration consulting different from building it?

Some firms advise on which systems to connect and stop there. Signa’s engineers choose the path with you, build it, test it on real cases and run it in production.

Who owns the integration?

You do. It runs in your accounts, with documentation your team can follow and change.
