Managing your users’ spending is complex. Automating it shouldn’t be.

You get structured results

Every action returns structured output and schema-validated JSON. Define the output and Deck delivers it consistently, ready for your pipeline.

Deck executes what your platform can only recommend.

Deck agents access the platforms your users interact with — benefit accounts, subscription services, recurring merchants — and execute spending operations on their behalf. Contributions, withdrawals, updates, cancellations — without requiring cooperation from the platform.

HSA and benefit account management

Deck handles contribution scheduling, withdrawal execution, and balance checks across HSA and FSA platforms — without requiring the provider’s API.

Subscription management

Update payment methods, change plan tiers, pause or cancel subscriptions — across any platform the user is subscribed to, automatically.

Recurring payment updates

When a user’s payment method changes, Deck updates recurring charges across the platforms they pay on — so nothing fails silently.

Auditable execution

Every action Deck takes is logged. Contributions made, amounts, timestamps, confirmations — all returned to your system. Full spend history, always current.

From instruction to confirmed execution.

1

User authorizes Deck

Through your product, the user grants Deck permission to act on specified accounts and platforms.

2

You trigger the action

Your system calls Deck’s API with the spend instruction: contribute X to HSA, update card on Netflix, cancel the unused subscription.

3

Deck executes and confirms

Agents complete the action and return a confirmation with the result. Failures are surfaced with context.

Frequently Asked Questions

Deck handles standard confirmation flows. For platforms with additional security steps, we scope those during onboarding.

Failures are returned with a reason — locked account, incorrect credentials, platform error. Your system decides how to handle them downstream.

The authorization model is transparent — users see exactly what Deck is authorized to do, and the scope is limited to what your product specifies. We can walk through the consent UX.

Any platform a human can log into and perform the action on. Coverage isn’t limited to signed API partnerships. Show us the platforms your users are on — we’ll tell you what’s feasible.

The gap between recommending and executing is where spend management products win or lose.

We’ll map your spend workflows and show you where Deck closes the execution gap.
