Reconcile Stripe and Lemon Squeezy revenue by API
Developer needs one net revenue figure across Stripe and Lemon Squeezy without reconciling exports by hand. Connect Stripe, PayPal, Shopify and your creator payouts. We normalize every source to one schema, match payouts to transactions, net out fees, refunds and FX, and hand back your real MRR plus tax-ready exports.
$9 fully refundable · front of the line for early access · founder price locked for 12 months once you are in · not a subscription
We are building the first connectors now. Reservers get access first.
Pre-launch: the API is in private testing. Reserve to lock founder pricing and help shape coverage.

Every source, one schema
Stripe, PayPal, Shopify, Lemon Squeezy and creator payouts normalized into one revenue object. Same fields, same currency, whatever the platform calls them.
Payouts matched to transactions
We tie each bank payout back to the underlying charges, net out processor fees, refunds and chargebacks, and convert FX so your net is your actual deposited revenue, not a gross guess.
Real MRR, not a dashboard estimate
Recurring revenue is deduped across sources and adjusted for refunds and failed renewals, so the MRR you report is the MRR you can defend to an investor.
Tax-ready the moment you ask
One endpoint returns a per-period export your bookkeeper or accountant can file from. No more exporting five CSVs and reconciling them by hand.
The API
One request in, one JSON response out.
Authenticate with a bearer token and send one request. Everything is versioned under /v1, so a breaking change always ships behind a new version, never under you.

Who it's for
Teams who would rather call an API than build and maintain this in-house. The biggest platforms may have rolled their own. Everyone else is stuck choosing between brittle scrapers, stale exports, and manual checks.
- Indie SaaS founders tracking true MRR across Stripe and resellers
- Freelancers and creators with income across many platforms
- Bookkeepers and fractional finance teams closing the books
- Marketplace sellers reconciling payouts to orders

Questions
How do you access my revenue data?
Read-only OAuth to each platform. You connect a source once, we only ever read payouts and transactions, and you can revoke access at any time. We never move money.
Which platforms are supported?
Stripe, PayPal, Shopify, Lemon Squeezy, and creator payouts (Gumroad, Paddle, and similar) at launch. Tell us which source you need next and we will prioritize it.
Is this accounting software?
No. SumFlow is a developer primitive you build on, not a ledger you log into. It returns clean, reconciled revenue over an API so you can put it in your own dashboard, investor update, or accounting tool.
How is this different from Plaid or an accounting suite?
Plaid reads bank transactions but cannot tell you which charges a payout settled or net out processor fees. Accounting suites make you connect and reconcile by hand. We do the matching, fee, refund and FX normalization and hand back one revenue object.
What does the $9 reservation get me?
It locks founder pricing for 12 months, a spot in the first cohort, and priority on the sources and exports you need. Fully refundable, anytime, no questions.
Who's building this
Micah Manzano, founder of Manzano Labs
I build the boring-but-critical plumbing so your team does not have to. Before this I built and shipped Nooma, an AI reporting platform used by marketing agencies, so I know what it takes to ship and keep real software running. SumFlow exists because I kept watching teams rebuild the same data plumbing from scratch.
I work hands-on with developers and care about one thing: removing the friction between you and the data you need. Email me directly at hello@manzanolabs.com. I read every one.
Shape the roadmap
Building this with the developers who'll use it.
What would make SumFlow an instant yes for you? Which states, lists, fields, or endpoints do you need first? Tell me and I'll build toward it. Every reply shapes what ships.
Reserve your key
$9, fully refundable. It tells us you're real and locks your founder rate. We build toward the first cohort's exact needs.
