Invoices at 11pm?

I kept missing

So I built Costella.

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.

  3. Before you pay anything

    You’ll see the price first. Stay or leave.

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.
