Saturn BPO
Outsourced controller + CFO for ecommerce

You know your revenue. Do you know your real margin?

Saturn BPO gives ecommerce operators a controller who reconciles every settlement and closes the books fast (we target the 10th when your records are complete), and a fractional CFO who turns that into real margin, a cash-flow forecast, and COGS discipline. Clean multi-channel bookkeeping and sales-tax accrual are step one, not the finish line.

The margin questions you can't answer

What a generic bookkeeper can't tell you about your store.

Sell online and your numbers have these six blind spots. We close them, then tell you what they mean for the business.

  • Settlements never tie

    Shopify payouts lag 2–5 days and bury fees in the gross. Your bank deposit never matches your sales.

  • Every processor books differently

    Stripe, PayPal, Amazon Pay, Klarna, Shop Pay. Most bookkeepers lump them into one revenue line.

  • Refunds rot in suspense

    Chargebacks sit uncoded for weeks. Your AR shows phantom revenue you'll never collect.

  • COGS is a year-end guess

    Inventory never reconciled against the platform. You don't know your true margin until April.

  • Marketplace tax is mis-booked

    Amazon, Etsy, eBay facilitator tax treated as regular revenue. Accrual wrong, filing wrong.

  • Nobody's forecasting cash

    No runway view, no read on which channel to scale. You're buying inventory on a hunch.

The shift

From deposits that never match to margin you can actually trust.

Before Saturn BPO

  • Shopify deposits never match your sales
  • Stripe fees buried in a generic expense bucket
  • Refunds sitting uncoded for weeks
  • COGS guessed, so margin is fiction until April
  • No forecast, no read on which channel makes money

After Saturn BPO

  • Every settlement reconciled, revenue net of fees
  • COGS booked monthly, real margin by channel and SKU
  • Sales tax accrued and tracked, filing-ready
  • A cash-flow forecast you can plan inventory against
  • A fractional CFO read on what to scale and what to kill

The real questions

What people actually ask before they sign.

Yes. And Stripe, Amazon Pay, PayPal, Klarna, Afterpay, Shop Pay Installments, plus marketplace facilitator tax mechanics for every US state with nexus. We reconcile to the settlement net, not the gross sales number, which is why your bank actually matches your books at month-end.
We work with whatever inventory system you're on: Shopify, ShipBob, ShipMonk, Cogsy, Settle. COGS is booked accurately each month against the platform's actual fulfillment data, not estimated at year-end. If you don't have an inventory system yet, we'll recommend one before onboarding.
We handle the sales tax accrual, nexus tracking, and monthly reconciliation. The actual filing goes through your sales-tax software of choice: Avalara, TaxJar, or Anrok are the common ones. We make sure the numbers feeding into it are correct every month, so filing day is mechanical, not a scramble.
Federal and state income tax returns are included via our integrated tax partner. They file directly from the books we keep. No separate CPA chain, no surprise cleanup fees in April.
Two to three weeks for a clean takeover. Four to six weeks if there's 12 months of cleanup we need to do first (more common than you'd think). We'll be honest about the scope after the discovery call. You stay on your current platform (QBO or Xero). No forced migration.
Most ecommerce engagements are scoped to your operation depending on transaction volume, channel count, and how much fractional CFO support you want. Custom quote in 24 hours after a 30-minute discovery call.

Know your real margin, not just books that are “coded.”

Thirty minutes. Bring your Shopify settlement report, your Stripe dashboard, and the inventory system you're using. We'll show you where your real margin is hiding and what to fix first.
