How it works

Three steps, start to finish

No calls required to get started, no long onboarding. Send your data, get something useful back.

01

You send your data

A CSV export from your POS, Shopify, or even a spreadsheet you've been keeping by hand. Whatever you've got.

02

I clean it and dig in

I sort out the messy parts and analyze what's actually happening in your sales — by item, by channel, by day.

03

You get a dashboard + findings

A clear dashboard plus a short write-up of what I found and what I'd do next. In plain English, no jargon.

Executive business dashboard for Bella's Corner Diner, showing revenue by menu category, top menu items, channel revenue, and daily sales trend.
Sample project

Bella's Corner Diner

A two-week sales export, cleaned up and turned into a one-page dashboard: what's selling, what channel makes the most money, and how revenue moved day to day.

What it showed: delivery orders had the highest average order value of any channel — but the lowest customer rating. A clear signal to look at delivery fulfillment before pushing more orders through it.
This kind of analysis also catches things like: a single menu category quietly making up more than half of total revenue — useful to know before assuming your revenue mix is more spread out than it actually is.
Pricing

Choose the depth of support you need.

Simple, upfront pricing. A one-off deep dive priced to how much history you hand over, or a cheaper monthly rate once we're working together regularly.

N

I'm Nadir. I spend most of my time cleaning up messy spreadsheets and turning them into something you can actually read — usually with Python and a lot of double-checking.

I like working with small restaurants and shops specifically, because the data is real and the questions are simple: what's selling, what isn't, and where's the money actually coming from. No corporate dashboards nobody opens — just answers.

FAQ

A few things people ask

We already track this stuff ourselves — is this still worth it?

Maybe, maybe not — that's exactly what the free sample is for. Send over your data and see if it turns up anything your current setup hasn't. If it doesn't, you've lost nothing; if it does, you know it's worth a second look.

My data is messy / I don't have a "real" export, just a spreadsheet I update by hand.

That's normal, and it's most of what I clean up anyway. Send whatever you've got — a POS export, a Shopify report, or a spreadsheet you've been keeping yourself — and I'll sort out the messy parts.

How long does the free sample take?

Usually about 48 hours from when I get your data, same as the paid version. No cost, no commitment either way.
