AI automation agency: unattended automation that alerts a person when a step fails
Hashlogics is an AI automation agency for working businesses: we build automation that reads your own systems, runs unattended, and hands a person the one step it should not decide, then we keep it running.

Automation earns its keep when it runs unattended against systems you own. Connecting two public SaaS apps is a settled problem, and a per-task tool solves it in an afternoon. The work that costs you a headcount is different. It touches a private database, needs a judgement call, and has to be right on a Sunday night.
Where the hours actually go
Ask a team where its time goes and the answer is rarely one big task. It is re-typing an order into a second system. Reading a transcript to find what somebody promised. Checking whether a job was invoiced.
Each one is small. Together they are a role. They survive because the systems involved were never meant to talk, and because the person doing the work applies judgement nobody wrote down. In an insurance agency that role is the CSR re-keying an ACORD packet, which is why we build insurance workflow automation as one system rather than a chain of SaaS glue.
- 01Data re-entered by hand because two systems have no shared key.
- 02Decisions made in a meeting that never reach the tracker.
- 03Work that only moves when somebody remembers to check.
- 04A spreadsheet that has quietly become production infrastructure.
What an AI automation agency does
An AI automation agency builds software that does a repeatable job on your systems without anyone watching it, then keeps it running after launch.
It starts with discovery. We follow one real process from end to end, read the systems it touches, and write down every hand-off. That is where you find the steps that should be deleted rather than automated.
Then it builds on your own systems, not around them: your database, your internal APIs and the tools your team already uses. The failure path gets designed before the happy path, and you see one workflow running on real data before we scope the next.
After launch, it stays accountable. Every run is logged, a named person is alerted when a step fails or goes quiet, and you get a runbook. You can train your own team to own it, or we stay on under an agreed service level.
Four shapes of automation
Real systems, named. Each of these is work we have shipped or work the same pipeline carries.
Unattended pipelines
A trigger fires, the work happens, and nobody watches it. Little Tree's meeting pipeline reads a Fireflies transcript, refines it with an OpenAI call, then creates ClickUp tasks routed to the right department.
Automation that decides
Some steps need a judgement, not a rule. A model reads the input and picks a route, with the prompt, the schema and the fallback all versioned. When it is unsure, a human gets asked instead of guessed at.
Systems that do not have an API
The tool holding your data may not want to share it. We reach it the way it allows: a database read, an export on a schedule, a scraped report. That is where SaaS-to-SaaS automation gives up.
The part that runs it
Retries, alerting, execution logs, and a place to see what ran. Automation without this is a demo that has not failed yet.
- TriggerWebhook, schedule or a row that changed.
- ReadYour database, not a copy of it.
- DecideRules where rules work. A model where they do not.
- WriteInto the system of record, with an idempotency key.
- FailRetry, log, then wake a human. Never silence.
Most automation projects build the first four stations. The fifth is the one you find out about at 2am.
Deciding what happens when a step fails
The canvas is the easy half. The real design work is failure. What happens when step nine of twelve returns a 500? And does re-running the whole thing charge your customer twice?
You get those answers before anything is built. Some steps are safe to repeat. Others need an idempotency key. The rest get retried, parked for a person, or escalated to whoever is on call.
- Every write is either repeatable or keyed, so a retry cannot double it.
- A failed run raises an alert with the input attached, not a silent log line.
- Credentials live in a store, never in the workflow body.
SaaS glue against systems you own
Both are legitimate. They fail in different places, and buying the wrong one is the common mistake.
What it reaches
SaaS-to-SaaS glue
Public apps with a published API.
Automation on your own systems
Your database, internal services, and the public apps too.
Where it runs
SaaS-to-SaaS glue
The vendor's cloud. Your data goes there.
Automation on your own systems
Infrastructure you control, so data residency has an answer.
Custom logic
SaaS-to-SaaS glue
A code step, sandboxed and limited.
Automation on your own systems
Whatever the problem needs, in ordinary code.
Cost behaviour
SaaS-to-SaaS glue
Billed per task, so high volume gets expensive.
Automation on your own systems
Billed as infrastructure, so volume is mostly free.
Who maintains it
SaaS-to-SaaS glue
Anyone on the operations team.
Automation on your own systems
Anyone, if it was handed over properly. Nobody, if it was not.
Honest verdict
SaaS-to-SaaS glue
Right for a handful of low-volume connections.
Automation on your own systems
Right once a failure has consequences somebody answers for.
RPA, API or AI agent: which one fits the step
Pick the tool by how the system lets you in. If it has an API, use it: an API integration is the most reliable automation there is. If the input is unstructured, like an email, a PDF or a transcript, an AI step reads it and an AI agent can decide the route. If a screen is the only way in, an RPA-style bot clicks through it, built with Playwright or Claude computer use, and we treat it as the fragile part it is.
We do provide RPA development services, but only for the steps that need them. If you run dozens of screen-only processes on a desktop estate and have an internal team to own them, an RPA platform such as UiPath is often the better buy, and we'll say so. Our glossary explains RPA and computer use in plain terms.
- 01Has an API: integrate through it.
- 02Unstructured input: an AI step reads it, a rule or a person decides.
- 03Screen only: an RPA-style bot, watched closely.

AI automation by industry
The same agency work looks different in each trade, so each has its own page: HVAC dispatch automation, logistics automation for 3PLs, brokers and fleets, shop-floor automation for manufacturers, property management automation, construction field-to-office automation, auto repair shop automation and oilfield ticket and dispatch automation.
Automation we run in production
From first call to something running
Scoping calls are free. Every build starts with a fixed-fee Blueprint: an engineer reads your real systems and writes the plan, with a fixed price for each milestone rather than a guess. The fee is credited in full against the build, and if the plan isn't one you'd act on, you don't pay for it.
- 01
Trace the process
One real case, followed end to end, with every hop written down. This is where the automation candidates appear. It is also where you find the steps that should be deleted rather than automated.
- 02
Design the failure path
Before the happy path. Which writes are repeatable, which need a key, what gets retried and who gets woken up.
- 03
Build one workflow
The highest-value process first, running against real data. You see it working before the second one is scoped.
- 04
Dry run on history
We replay past inputs through the pipeline and compare against what actually happened. For Little Tree that meant running historical transcripts before anything went live.
- 05
Hand it over or hold it
Your team gets trained on the workflows and the runbook. Or we stay on under an agreed service level. Both are real options, and neither is the default.
How an AI automation agency charges
A good AI automation agency charges for a written plan first and for the build in fixed pieces, never by the hour.
Every engagement with us starts with a fixed-fee Blueprint. An engineer reads your real systems and writes the plan. The fee is credited in full against the build, and if the plan isn't one you'd act on, you don't pay for it.
The build then runs as fixed-price milestones, each accepted against written criteria, so you know what done means before work starts. Afterward you choose a service level or a trained handover. A month where we miss the written service levels is a month you don't pay for.
What an AI automation agency should hand over
An automation without an owner is a future outage. Whether we stay on under an agreed service level or train your team, you get three things in writing before go-live.
- 01A runbook: what each workflow does, what it touches, and how to re-run a failed step safely.
- 02Alerts routed to a named person, on errors and on silence, with the failed input attached.
- 03An owner: one engineer on our side, and one person on yours, named in the document.
“Their attention to detail, quality of employees, and work ethic were outstanding.”

Questions buyers actually ask
01What does an AI automation agency build?+
An AI automation agency builds workflows that run without a person watching: reading documents and transcripts, moving data between your systems, deciding routine routes, and alerting someone when a step fails. Hashlogics builds these on n8n, Make, Zapier or custom code against your own systems, then keeps them running.
02Which companies build AI automation for a business like mine?+
Hashlogics builds AI automation for working businesses, from trades and logistics to law firms and property managers. Each industry page names the systems we connect, such as QuickBooks Online, Google Workspace, Microsoft 365, the OpenAI API or the Claude API, and what stays with a person.
03Should we use Zapier, Make or n8n, or a custom build?+
Use Zapier or Make for simple, low-volume connections between public apps. Use n8n when you need self-hosting, a code step or high volume without per-task billing. Use custom code when a half-finished run is a real incident. We often mix them.
04Who keeps an automation running after it ships?+
Either we do, under an agreed service level, or your team does after a documented handover with a runbook, alerts and a named owner. Pick at the start. An automation nobody owns stops quietly.
05Do you provide RPA development services?+
Yes, for the steps where a screen is the only way in, using Playwright or Claude computer use. Where an API exists we integrate instead, because it breaks less. If you run many screen-only processes and have a team to own them, an RPA platform like UiPath may suit you better.
06How much does it cost to hire a workflow automation consultant?+
There's no honest figure before an engineer traces your process and reads your systems. The scoping call is free. Every build starts with a fixed-fee Blueprint, credited in full against the build, and if the plan isn't one you'd act on, you don't pay for it.
07Will this break the moment one of our tools changes?+
Parts of it will, and the design decides how loudly. An automation reading a documented API survives most vendor changes. One reading a scraped report does not, so that part gets isolated and alerted on rather than treated as stable. A failure you can see is cheap. The one that runs silently wrong for three weeks is not.
08Do we have to use n8n?+
No. n8n is the default when a non-engineer has to read the workflow later, because the canvas stays legible to someone who did not build it. When a half-finished run is a real incident, a written service and a durable queue are the better answer. The tool follows your failure requirement, not our preference.
09Can automation touch our production database?+
Yes, and that is usually the point. Self-hosted n8n runs on your infrastructure, so your data never goes to a vendor's cloud. Reads come first. Writes go through the same review any application change would get, and every write into a system of record carries an idempotency key.
10What does it cost to run?+
Where it runs decides that, and the two models behave differently. Zapier bills per task, counting each successful step in a Zap. n8n Cloud bills per execution, meaning one full workflow run whatever its size. Self-hosted automation is billed as infrastructure instead: a container, a database, and someone who owns upgrades. High-frequency work is where the gap stops being academic.
11How much of this should be AI?+
Less than most vendors suggest. A model belongs where the input is unstructured or the rule is genuinely fuzzy, such as reading a transcript for commitments. Everywhere else a plain rule is cheaper, faster and testable. Little Tree's pipeline uses both, and the boundary between them is written down.
12Who owns it afterwards?+
You do. Workflows export as JSON, the code inside them is ordinary JavaScript or Python, and your credentials stay in your own store. Your team gets trained on it, or we stay on under an agreed service level. The first 2 months of support and maintenance are free, with every build. What you never get is a system only its author can maintain.
