Agencies burn budget across a dozen AI tools and APIs, with no idea which client it's for. SpendGuard is the control tower: track every call and subscription, attribute it to the right client, and rebill with margin.
14-day free trial · No credit card to start · Set up in minutes
One big number per provider, per month. No breakdown by person, by client, or by project. By the time you see it, the money is gone.
Which client did this $4,200 OpenAI bill actually serve? Nobody can say.
How many AI subscriptions are we paying for, and who's still using them?
We could rebill AI cost to clients with margin, if only we could measure it.
Three things, in one place, built for how agencies actually work.
A proxy sits between your team and the AI APIs. Every call is logged with who, what, when, and exactly how much, across OpenAI, Anthropic, Runway, ElevenLabs and more. Budgets stop runaways before they hit the invoice.
Per-user · Per-provider · Real-timeTrack every fixed AI subscription, ChatGPT Team, Midjourney, Runway, Canva, with seats, renewal dates and monthly cost. SpendGuard combines subscriptions and API spend into one total, and warns you before renewals.
Seats · Renewals · Total costTag every call to a client, project or deliverable, by key scope or a request header. Then run rebilling reports: cost, your markup, and the billable amount per client, exportable to CSV. This is the part other tools don't do.
Attribution · Markup · CSV exportSpendGuard is the only AI spend tool built around per-client rebilling. Set a markup, pick a period, and get a clean breakdown ready for the client invoice.
Unlimited AI providers and proxy keys on every plan. You only pay for seats and features.
Every plan starts with a 14-day free trial. Prices in USD, billed monthly.
"We built SpendGuard because we were running AI across two agencies and flying blind. It's the dashboard I wished existed, so we made it." — Meinte Stinstra, Founder, JackandAI
Your team's tools point at SpendGuard's proxy instead of the provider directly, via a base URL and a SpendGuard key, the CLI, or our SDK. SpendGuard forwards the call to the real provider, logs the cost, and returns the response. Your real provider keys stay encrypted on our side and are never exposed to your team.
Usually just two environment variables, or one line with our SDK. For OpenAI and Anthropic it's a base URL swap. The CLI configures it for you. Streaming, tool use and the rest keep working.
Two ways. Scope a proxy key to a client, project or deliverable so everything through that key is attributed automatically. Or pass an X-SpendGuard-Client header per request when one key serves many clients. The rebilling report then rolls cost up per client with your markup.
OpenAI and Anthropic with full streaming, plus Runway, ElevenLabs, Replicate, Stability, Fal, HeyGen, Higgsfield and Adobe Firefly out of the box. Any other provider can be added with a pricing template, no code.
Provider API keys are encrypted at rest. Each workspace is isolated, no workspace can see another's data. SpendGuard never forwards your SpendGuard key or attribution headers to upstream providers.
Pick a plan to keep going. If the trial ends without a plan, proxied API calls pause but your dashboard and all historical data stay fully readable, so you never lose visibility.
