How Automation Saves Us Around 20 Hours a Week
We run Teralith on a back-office system we built for ourselves. It invoices, reconciles the bank statement, watches every client site, drafts every reminder, and runs a new client from first email to signed contract. The owner's estimate is that it saves him around 20 hours a week. That is an estimate from doing the work both ways, not a measurement, and this piece says what is behind it.
An earlier version of this article claimed 20 hours for businesses in general and priced it in dollars. We took that down. The only numbers we can stand behind are our own, so those are the ones here.
Where the hours went before
A one-person studio spends its evenings on admin. Before the system, a week held most of this: raising the month's invoices by hand and remembering which instalment was which; typing receipts; going line by line through a bank statement to work out which payment was which client and which charge was which subscription; opening each client site to check it was still up; writing the same "your invoice is overdue" email for the third time; writing quotes from scratch; pasting a contract together; and, once a client signed, remembering to send the deposit invoice.
None of it is hard. All of it is repetitive, all of it has to be right, and every hour of it is an hour not spent building.
What runs on its own now
Here is the inventory, with what the system does and what a person still does. The second column is the point.
| Loop | What the system does | What a person does |
|---|---|---|
| Recurring invoices | Issues every monthly invoice and instalment on its date, counts the instalments, and pauses a plan when the last one is paid. | Nothing, unless a client asks for a change. |
| Receipts | Emails the client a receipt the moment a payment is recorded, with the invoice stamped paid and the balance after it. | Records the payment. |
| Bank statements | Reads the monthly statement, proves the balance to the cent, and matches lines to invoices and subscriptions. | Confirms the matches it is unsure of. |
| Site monitoring | Checks every client site every few hours and emails us when one goes down and when it comes back. | Fixes whatever went wrong. |
| The Monday digest | Every Monday, one email: reminders due, overdue invoices, the week ahead, site exceptions, last week's cash. | Reads it. |
| Onboarding | From a name and an email: sends the intake link, drafts the quote from what the client picks, composes the contract on acceptance, sends the deposit invoice on signing. | Confirms the quote before it goes, then builds the site. |
| Chasing | Overdue invoices, unsigned contracts, and quiet leads each climb a ladder, and a reminder is drafted at each rung. | Reads the draft and sends it, or does not. |
| Check-ins and renewals | Lists clients we have not spoken to in three months, with their site's uptime figures, and annual plans due to renew, with what the year covered. | Sends the note. |
| Backups | Exports every business table to private storage nightly and keeps thirty days. | Nothing. |
The rule that makes it safe
The system drafts; a person approves. Fixed, templated emails send themselves: a receipt, an intake link, a signing link, a deposit invoice. Their wording was written once and reviewed once. Anything with prose in it, a follow-up, a check-in, a quote for a scope that is not standard, is drafted and waits for a person to read it and press send.
That rule is why we can leave it running. Nothing a client receives was written by a machine without someone looking at it first, and the two kinds of email are kept apart on purpose so a dashboard can never quietly blur them.
Where the 20 hours comes from
Mostly from three places. The bank statement, which used to be an evening a month and is now the time it takes to confirm a handful of matches. Chasing, which used to be writing and is now reading. And onboarding, where a new client used to mean a quote, a contract, and an invoice typed by hand over a week of back and forth, and now means confirming a quote the client already picked.
We have not put a stopwatch on it. If we do, we will publish the number and replace this paragraph.
What this means for your business
Your repetitive work is not ours. A clinic has intake and reminders. A firm has quotes and follow-ups. A shop has stock and reorders. The shape is the same: something arrives, a draft is made, a person approves it, and the routine part of the day gets shorter.
You do not need to automate everything at once. Start with the one loop that costs you the most evenings. That is what AI Ignite is: one workflow, automated end to end, from USD 1,250. Prove it saves what you think it saves. Then decide about the next one.
