I built Insighty because my own agency was forgetting to invoice €30,000 a year.

The handover that broke everything

We were a seven-person agency. We'd been running for four years. We had 30-something active clients — hosting for some, WordPress maintenance retainers for others, mixed packages for a few. Nothing exotic.

Then, over eight months, three people left. The project manager who owned the hosting contracts. A developer who handled half the maintenance clients. A junior who'd been managing domain renewals via a spreadsheet nobody else could find.

The handovers were what they always are: rushed, incomplete, and optimistic. "It's all in the Drive folder." It wasn't. "Just check the email thread." There were 400 email threads.

We kept running. We kept doing the work. We just stopped tracking whether we were billing for it.

The spreadsheet that lied to me for two years

I had a master billing spreadsheet. I'm not proud of it. It was 12 tabs, colour-coded, completely manual. Every month I'd open it, squint at a few rows, and convince myself everything was roughly under control.

What it couldn't tell me: which clients had active hosting contracts that weren't in the invoicing system. Which maintenance retainers had been paused — temporarily, everyone said — and never restarted. Which domains we were managing but nobody was charging for anymore.

The spreadsheet showed me what I entered. It couldn't show me what I'd forgotten.

The audit that changed everything

When I started building Insighty, the first thing I did was import our own data. Every client. Every service. Every contract. Every hosting environment. Every domain. Every maintenance tier.

It took two evenings. Then I ran a report I called "Services with no attached invoice in 90 days." I expected a handful of edge cases. What I got was a list of 23 line items.

Twenty-three services across eleven clients that had been running — work was being done, infrastructure was live — and nobody had sent an invoice in three months or more. Four of those clients hadn't been billed in over eighteen months.

One client: we'd been managing their WordPress site and two domains for twenty-two months. No invoice. The contract was in a folder with the previous developer's name on it. The work had continued; the billing had quietly died.

What we found, and what we did

I pulled together the numbers over a weekend. Across all the missed invoicing: €18,400 in work that had been delivered but never billed for in that calendar year. Some of it recoverable from clients (most were fine with it, a few required honest conversations), some we had to write off.

But the bigger find wasn't the missed invoices. It was the upsells.

When all the data was in one place, I could see the service history for every client. Three clients on basic hosting plans were running high-traffic sites — they'd grown since we'd set them up. Two clients had never been offered our performance maintenance tier, despite having precisely the kind of WordPress setup that breaks without it.

We had structured conversations with five clients within a month. Four upgraded. One declined, which is fine — at least we asked.

The total swing from that first audit: over €30,000 per year in recovered and new revenue. And that's not counting what we'll never lose again because everything is now tracked, invoiced automatically, and flagged the moment something goes uninvoiced for 30 days.

Why I'm telling you this

I built Insighty because I was tired of running an agency on vibes and manual spreadsheets. I thought we were competent. We were. We just had no system for the thing that matters most: making sure every piece of work we delivered resulted in revenue.

The worst part isn't the money. It's that this was all preventable. The data existed. The contracts existed. The work was documented. We just had no way to see across all of it at once.

That's what Insighty does. It doesn't do the work for you. It makes sure you can see everything — and that you never quietly forget to invoice a client for the third year in a row.

If you're running an agency, I'd be willing to bet there's a version of this number somewhere in your ops right now. You just don't have a way to see it yet.
