The spend that never shows up in a subscription list.

Cloud infrastructure, API and AI usage, ad spend, domains, digital assets, plugin marketplaces, telecom, and payment fees — tracked, categorized, and given an owner, separately from your SaaS subscriptions.

Eight categories of spend that hide in plain sight

None of these look like a “subscription” on a statement, so they rarely end up in a subscription tracker — but they're real, recurring, and usually growing.

Cloud infrastructure

AWS, GCP, Azure, and other infrastructure bills that scale with usage, not headcount.

API & AI usage costs

Per-token and per-call charges from LLM providers, data APIs, and other usage-metered services.

Ad spend

Google, Meta, LinkedIn, and other ad platform accounts that draw down a balance daily.

Domains & hosting

Registrar renewals, DNS, and hosting plans that auto-renew for years without anyone noticing.

Digital assets

Stock media, fonts, design assets, and other one-off or recurring digital purchases.

Plugin marketplaces

App store, browser extension, and platform plugin charges tied to a tool, not a person.

Telecom & messaging

SMS, voice, and messaging API costs that spike with usage and rarely get reviewed.

Payment processing fees

Gateway and processor fees that scale quietly with transaction volume.

Why digital spend needs its own tracking

It’s often larger than the SaaS bill

Usage-based costs like cloud and API spend can outgrow every subscription combined — and still go unreviewed.

Nobody owns it by default

A subscription has a buyer who signed up for it. Infrastructure and usage-based spend often doesn’t — it just runs.

It moves every month

Usage-based charges scale with traffic, tokens, or transactions, so last month’s number doesn’t predict this month’s.

It’s spread across many small vendors

Individually small line items rarely trigger a review, but the total adds up fast.

Tracked separately from subscriptions, on purpose

Digital spend behaves differently from a SaaS subscription — it doesn't have a fixed price, a renewal date, or a signup flow. Sendlum keeps it in its own registry with its own categorization, instead of forcing it into a subscription record it doesn't fit.

Every category is assigned an owner and a cost center, the same way a subscription is, so usage-based spend gets the same accountability instead of falling through the cracks.

How it works

1
Connect your data

Link your bank and accounting tools so Sendlum can see charges that don’t match a known subscription.

2
Auto-categorize

Every charge is sorted into cloud, API/AI, ads, domains, assets, plugins, telecom, or fees.

3
Review in the Discovery Inbox

Detected spend is a suggestion, not a fact — a person confirms it before it’s tracked, nothing is ever silently added.

4
Assign an owner

Attach a department and a person responsible, so usage-based spend doesn’t stay unowned.

5
See it as its own line

Digital spend reports separately from subscriptions, so finance sees the full, real picture.
