AI process automation for internal and back office work

Say what you need. It does it.

An assistant built to your company's measure for the administrative work that repeats every week. It reads, classifies, reconciles accounts and prepares what management has to decide on, working 24 hours a day.

01  The work nobody sees

The administrative work nobody has as a job.

Reading the inbox and sending each message to the right person. Copying the amounts off an invoice into the accounts. Checking who paid and who did not. Pulling the numbers together for Monday's meeting.

It is not what you sell

It shows up in no report.

It is not the work the company gets paid for and it has no clear owner. It is split between the owner and one or two people in the office. But it gets done every week, by people who cost money.

Where mistakes pile up

The invoice that never got posted comes from here.

Nobody can do repetitive work with attention for very long. The payment nobody chased and the double entry are always born in the same place.

It does not wait

Monday's meeting is on Monday.

The invoice has a due date and whoever wrote is waiting for an answer. So it eats the time of someone who already had enough to do, often the owner's own.

This work is split across several people, and so nobody knows exactly how many hours it takes. Counted for the first time, the number is almost always bigger than anyone thought.

02  What hiring for this costs

A personal assistant costs $69,113 a year.

That is the federal median wage for administrative assistants, plus what an employer pays on top of it. The wage is where the company's math starts, not where it ends.

Real annual cost of hiring an administrative assistant in the United States
Wages, the federal medianThe Bureau of Labor Statistics median for secretaries and administrative assistants, May 2025$48,310.00
Employer payroll taxes, 7.65%Social Security and Medicare, paid by the company on top of the wage$3,695.72
Other benefitsInsurance, paid leave and retirement. Benefits run at 30.1% of what an employer pays$17,107.30
Real cost to the company$69,113.02

That is $5,759 a month, or $33.23 for every hour actually worked.

And then there are the hours nobody covers.

A person works forty hours a week. The week has one hundred and sixty-eight. Even paying for the whole year, this work is covered for under a quarter of the time.

40 hours paid 128 with nobody

Vacation, sick leave and training get paid all the same, and workers' compensation insurance sits on top of this math. When the person leaves, training the next one starts from zero.

03  What starts running on its own

Eleven internal processes that start running on their own.

These are examples of what usually comes in. Every company's list is its own.

  • 01

    Email triage and routing

    The inbox is read at any hour and each message goes to the right department, already with a summary of what it says. In the morning, whoever runs the place gets the inbox in order of urgency and without the junk.

  • 02

    Reading invoices and receipts

    Invoices in PDF get read, and the company name, the tax ID, the amount before tax, the rate, the due date and the account number come out in a table ready to post into the management software the place already uses.

  • 03

    Account reconciliation

    The bank statement is cross-checked against invoices issued and received. Whatever is unpaid is flagged to management, with the name and the amount.

  • 04

    Fixed cost audits

    The electricity, telecom and software invoices are read with the history next to them. Consumption that rises without explanation, or a contract that got expensive, is flagged with the amount at stake.

It is work that gets done every day and is never finished.

When a document arrives incomplete, an invoice photographed sideways or a receipt with no tax ID, the field stays unconfirmed and the document goes to a person. A value is never filled in on a guess, because an invented number in the accounts costs more than a blank field.

04  What it gives back

Automation gives back thirty-two hours a week.

And it does not clock out at six. The hours below are an illustration. Yours get measured in the assessment, before anything is proposed. Each hour is at $33.23, the real cost of the assistant from the math above.

Hours given back per week and annual value, by operation
OperationHours per weekPer year
Email triage and routing6 h$8,773
Reading invoices and receipts5 h$7,311

Qualifying requests and forms3 h$4,386
Screening applications and meetings3 h$4,386
Connecting isolated tools2 h$2,924
1,408 hours a year32 h$46,786

There is one figure that is not in this table. Unbilled invoices and payments nobody chased are revenue, and they are worth more than these hours. Whatever the audit cuts from an invoice stays cut every month.

That is $46,786 of the $69,113 of the hire, with the system running 24 hours a day.

05  How it works

First the system learns the company. Only then does it work.

Before it does anything, the system has to know what your company is. The rules, the services, the house vocabulary, what gets done and what never gets done. Without that base, it guesses.

Step 01

The documents

The business gets written down: what it is, how it works, what it does and what it never does.

Step 02

The index

It tells the system where everything is, so it reads in the right order before answering.

Step 03

The operations

On top of the documents, each concrete job of the business, built to measure.

Step 04

The conversation

You ask in plain English. There is no panel to learn and no fields to fill in.

A Tuesday morning question, answered with the company's own numbers.

What becomes yours

The structure built at the start, the documents and the operations, is your company's property. You paid for it and it serves only your business. The tool accounts are in the company's name from day one, and the system has access only to what each process needs, never blanket access because it is easier to configure.

What gets built belongs to your company Talk to us
06  The limits

What automation never does.

Four lines that always stay with your team, and it is that way on purpose.

The business decision stays yours

Approving an expense, writing off a debt or changing commercial terms arrives ready to sign. If you want it to become automatic, the rule gets defined and it does. The choice is yours, not the system's.

It does not act without leaving a trail

Everything it does is logged and it is possible to see why. Automation you cannot audit is a liability, not an asset.

It does not replace the accountant

It organizes, classifies and prepares. Whoever answers to the tax authority is still the company's accountant.

It does not run on a badly designed process

Automating a bad process only makes it faster at repeating the same mistake. First it gets tidied up, then it gets automated.

Every number comes with its source page

The summary arrives with the document attached and the page where each number sits. There is no hunting for the PDF to check.

It does not fill in what it did not read

An incomplete document stays unconfirmed and goes to a person. An invented number in the accounts costs more than a blank field.

07  What it is built with

Integration with the tools you already use.

The system goes on top of what exists. The management software does not get swapped and the team is not asked to learn another place to write the same things.

What we build with

Each piece does one thing only. They are picked to suit the business. There is no single recipe.

And it connects to what you already have

No new tool gets imposed. It connects to what the place already opens every day.

08  How it starts

How a project of process automation starts.

The hours get counted before there is a proposal. The first step is understanding how the work actually happens in your company, and everything else comes from there.

01  Assessment

Mapping each process as it exists today, including the exceptions nobody ever wrote down, and counting the hours it takes. Without these numbers there is no way to prove return at the end of the first month.

02  Scope and investment

Which processes come in, what stays out and what it costs. Written before anything gets built, so there are no surprises on the invoice.

03  Running

The system built and tested against your business's exceptions, not only against the case that goes well. At the end of the first month, the numbers against the ones at the start.

Not every process is ready to automate. If the rules contradict each other, or if part of it exists only in one person's head, the assessment says so plainly, and the process gets tidied up first. Sometimes the honest answer is that it is not worth it, and we would rather say so before charging you anything.

The hours that leave your week show up on the map, and that is where you see what changed.

09  Frequently asked

What people usually ask before going ahead.

If yours is not here, ask it directly.

Is this going to replace people on my team?

No. What comes off people's desks is the work that has no owner, the kind always left for the end of the day that nobody was hired to do. The hours given back go to the work the company gets paid for.

Do I have to change the tools I already use?

No. The system goes on top of what already exists: the email, the drive, the spreadsheets, the invoicing and the management software. If something does not allow a direct connection, that is said in the assessment and another route is found before there is a proposal.

Who owns what gets built for my company?

You do. The documents, the index and the operations built at the start are your company's property, because you paid for them and they serve only your business. The tool accounts are in the company's name from day one.

Where does my data live and who has access?

The principle is least access. Each process has access only to what it needs, never blanket access because it is easier to configure. Everything the system does is logged and it is possible to see why. The client is the controller and Sakuzo is the processor.

What happens if the process is badly designed?

We say so, and it gets tidied up first. Automating a bad process only makes it faster at repeating the same mistake. An assessment can end with the answer that it is not worth automating, and it is better to say that up front.

How long before you can tell it worked?

As soon as the system goes live, the hours start coming back that same day. The formal proof is done with numbers: the hours of each process are counted in the assessment, before there is a proposal, and compared with the system already running.

Start with a conversation

Half an hour is enough to know how many hours you are spending on this.

No commitment. We bring the questions, you bring your business's numbers, and we both leave knowing where to start.
