The Problem
Your vendors are counting on you being too busy to notice.
Tracking every cost across a dozen vendors and thousands of items by hand is impossible. That's arithmetic, not effort. We do the arithmetic.
The quiet cost creep
Distributors nudge costs up a few cents at a time across hundreds of items. Each one is too small to notice. Together they bleed your margin all year long.
The discount that becomes a price hike
A vendor runs a promo, you stock up, and when it ends the base price comes back higher than before. Almost nobody catches it.
Prices that never caught up
Your cost went up in the spring. Your shelf price is still set from last year. Every sale since has quietly made you less than you think.
You put the paper in a box. We find the money.
No new software. No new task for your clerks. The hard parts are ours.
Drop invoices in the box
Every vendor invoice goes in one Nightcap Invoice Box. No app, no portal, nothing new to learn. All invoices go here.
We do the math
We read every invoice, match each item to your prices and your sales, and find every cost increase, broken margin, and overcharge.
You get a fix list
A short list of which prices to change and which vendors to question — ranked by the money it puts back in your pocket.
Built for how stores actually work.
No portal. No new daily software. Every vendor invoice goes in the Nightcap Invoice Box. We handle the rest — the scanning, the reading, the matching, and the math.
- One box on the counter. All invoices go in.
- We digitize them for you — or come scan them in person.
- Cost-change alerts the moment a vendor raises you.
- Duplicate invoices and overcharges flagged automatically.
- A real person helps you get set up. You sort nothing.
Every leak in your store — found and ranked.
You'll see what changed, what it's costing you, and the few fixes that win back the most money first.
- Vendor cost increases, the day they hit
- Best sellers now selling below your target margin
- The post-promo price hikes vendors slip in
- Your true cost of goods, item by item
