Invoices at 11pm?

I kept missing
supplier price rises.
So I built Costella.

Your inbox

Forward the invoices you already get.

PDF invoices by email. A supplier she doesn’t know yet? She asks you to confirm each line.

Every line

She circles the rise. You say yes.

Butter went from $50 to $56 a block. She circles it and waits for your yes.

Next morning

One summary with your morning coffee.

What went up, which dishes it touched, and what’s waiting for you.

Not sure?

She never guesses. She waits for you.

If she can’t read or match a line, she won’t pick for you. It waits for your tap.

Your dishes

Know what a plate costs you today.

After your yes, brown butter gnocchi costs 12 cents more a plate. Each cost shows where it came from, or what’s missing.

Who made this

I run a restaurant too.

I’m Alphonse. I run Pho Heaven, a Korean-Vietnamese restaurant in West Auckland. I built Costella for my own kitchen first.

One honest limit: She knows six suppliers’ layouts so far. For any other, you confirm each line.

Before you join

“Will it get my numbers wrong?”

She never guesses. A line she can’t read or match waits for your tap, and every number shows where it came from, or what’s missing.

“Does it read my suppliers’ invoices?”

PDF invoices by email. She knows six suppliers’ layouts so far. For any other, she asks you to confirm each line.

“Other apps do this. Why this one?”

They read invoices too, and some ask before a price changes. Costella has no setting that skips your yes, and each cost shows where it came from.

“My spreadsheet already does this.”

Keep it if it works for you. A spreadsheet waits for you to type each new price. She reads it off the invoice and shows you the line it came from.

“What’s the catch?”

Three months free with your real invoices. The price after that is set before launch and shown here first.

“Can I leave?”

Yes, whenever you like.

Leave the invoices for the morning.
