Spend management built for the AI era
Stop sharing company cards
Give every subscription its own card, with its own budget, limits, and approvals. No more shared cards, no surprise charges, no misuse. Create a virtual card in seconds, suspend or close it in one click. Running Facebook for three clients? A card each, so spend stays clean and separated.
See all the tools you pay for
Every tool your company pays for, in one place, with an owner, a cost, and a purpose. The whole stack, finally visible. No more “who set this up?” six months after someone left.
Chasing receipts isn't for humans
Receipts collect and match themselves automatically. Even the ones vendors never send, think ad platforms and AI tools, our Receipt Fetcher goes and gets. Everything reconciles and flows straight to your accounting, so the books are done before you think to ask.
Catch every cost before it spirals
See what every tool actually costs, optimize what you're overpaying for, and catch the spikes while you can still act. Your AI token spend doubled this month? You'll know before the receipt, not after. You're paying for 30 seats and using 16? Now you'll know.
And yes, it works with your accounting
Export or sync to the tools you already use. Set it once, and it just keeps flowing.

Cardboard brings clarity back to business
The world is full of "smart" solutions. So smart they made everything stupidly complicated. We're not here to add to the noise. We're here to eliminate it. We're bringing clarity back to business.
97% of users love and recommend Cardboard
Cardboard Net Promoter Score (NPS) survey, Feb to Mar 2026.
“2 months ago we switched our model and our AI cost went up 40%. That's the stuff I care about, not who spent what on coffee.”
“After Cardboard, we identified over 20,000 EUR in subscription savings a year.”
“With Cardboard, we hit 95% SaaS expense automation. Finance stopped chasing.”

Across all 102 subscriptions, Google Ads leads at 46,846 EUR, 58% of your top four. Here is the breakdown:
Top 4 by spend · 12 months · subscriptions only
Two overlaps. Notion and Confluence both run docs, Figma and Sketch both run design. 9,240 EUR a year for four tools doing two jobs.
If tools run your business, this is for you
Tech companies
Startups, scaleups, and everyone past it.
Your stack doubles every time you raise. One quarter it's twelve tools, the next it's sixty, and nobody remembers approving half of them. Cardboard keeps up as fast as you hire, so the month your AI bill jumps 40%, you know then, not at quarter end.
Marketing agencies
Every client, separately tracked.
You're running Facebook, Google, and a dozen tools across a dozen clients, and at invoice time it's your problem to untangle who spent what. Give every client their own cards. Every ad platform, every subscription, tagged and traceable, so client billing stops being a monthly forensic exercise.
IT and tech consultancies
Bill it back without the spreadsheet.
Different projects, different environments, different clients, all charging to the same vendors. AWS for prod and dev, tools spun up for one engagement and forgotten after. Cardboard keeps every card mapped to the right project, so cost allocation and rebilling are done before finance even asks.
Stop tolerating the mess
Clarity and control over every tool you pay for. Automated.
