For the lone finance lead
If you're the one person doing anything resembling finance at a 10-30 person startup, subscription tracking is one of the dozen jobs quietly falling on you. Here's how CostLens handles it.
TL;DR
- If you're the only person at a 10-30 person startup doing anything resembling finance, subscription tracking is one of the dozen jobs quietly falling on you. This page is for that job.
- CostLens is a ledger, not a platform. You add each sub once; it watches renewals (30/15/7/1 days), flags duplicates, tracks budgets. Setup under an hour, flat $12/mo.
- If you want auto-discovery, virtual cards, or procurement help, you want a different tool. We built CostLens for the job specifically, not the category.
Built for
- The founder-finance-ops hybrid running the spend side of a 10-30 person team
- The first finance hire at a scale-up, inheriting a sub tracker that hasn't been opened in a month
- A fractional CFO or accountant who has to know about SaaS spend without being there daily
- The ops lead who got handed "subscription tracking" because nobody else would do it
What the work actually looks like
Nobody at your stage has a dedicated finance operations person. The CFO, when you have one, is fractional. The accountant lives in QuickBooks and doesn't think about SaaS as a category. The engineering team buys tools without asking. The founder signs up for things on personal cards and forgets to say so.
The job of "knowing what we pay for and when it renews" falls on one person. That person is you, whether your title says it or not.
You probably have a spreadsheet. It was current three months ago. You know two subs that are missing and you're not sure which ones. An annual renewal for a tool you thought nobody used anymore charged last week, and you had to explain it to the founder over Slack. The quarterly review you scheduled last year has been skipped twice.
This is the job. It's not glamorous, and nobody will notice if you do it well. They'll absolutely notice if you don't.
Five things that actually help
- Renewal reminders that reach YOU, not a shared inbox.Calendar invites sent to a shared finance inbox get ignored. Reminders to you personally, 30/15/7/1 days before each charge, get opened.
- A structured ledger, not a text blob.Vendor, cycle, cost, owner, category. Five fields. Sorted and searchable. One row per sub.
- Duplicate flags.When someone sets up a second Notion workspace on a different email, you want that flagged within a week, not during next quarter's review.
- Budget ceilings per category.Engineering's monthly SaaS budget is $2k. When you cross 80%, get an email. When you cross 100%, have the conversation.
- CSV export for handoff.The accountant, the auditor, the investor due-diligence request — they all want a spreadsheet. One-click export keeps you from copying rows by hand at 11pm.
What the tool does
CostLens is the five-things list, shipped as software. You add each subscription by hand; from there, the app watches the dates, flags the duplicates, counts the spend against your budget ceilings, and emails you when something needs attention.
Nothing connects to your bank, your cards, or your Gmail. Setup is under an hour for a 20-sub ledger. $12 a month flat, or $108/yr. Up to 3 workspace members on Pro (you, the founder, maybe one ops person).
If you're past 100 subscriptions, or if you need virtual cards for SaaS purchases, or you want auto-discovery from a card feed — different tool. The /compare page covers Cledara, Substly, and Sastrify honestly so you can pick the right shape.
Frequently asked
I'm not really a finance person. Is this the wrong tool for me?
Probably not. Most of the people using CostLens aren't "finance people" — they're ops leads or founder-types who ended up doing the subscription-tracking job because nobody else would. The tool is built for that shape of user. If you can fill in a Google Sheet, you can use CostLens.
How is this different from just using a Google Sheet?
You still add subscriptions by hand (that part stays). What changes: the spreadsheet doesn't send emails when renewals are coming up, flag duplicate vendors, or track budget ceilings per category. CostLens does all three. The mental model is the same, the maintenance overhead is lower.
Do I need to connect a bank account or card?
No. CostLens never asks for card access, bank feeds, Gmail, or SSO. You enter each subscription yourself. The ledger only contains what you put in it — no auto-discovery means no surprises about what the tool "found."
What if I have 100+ subscriptions?
Then CostLens is probably the wrong fit. At 100+, auto-discovery saves enough time to justify the added setup and security review of a platform like Substly or Cledara. See the full comparison at /compare for how those differ from us.
Can I invite my CEO or another teammate?
Yes. Pro supports up to 3 workspace members. Most startups use the founder + the finance lead + maybe one ops person. If you need more than 3 seats, email [email protected] and we'll work something out.
What happens when I outgrow CostLens?
You export your subscription list as CSV (one click on Pro) and import it into whatever tool fits the new team shape. Your data is never locked in. We'd rather you leave cleanly than stay on a tool that doesn't match your scale.
How much time does this actually save me?
Hard to quantify honestly. What we hear from teams: the first value shows up the first time a renewal alert stops a surprise charge you'd have missed. After that, the quarterly audit takes 20 minutes instead of two hours because the data is already structured.
