Your e-commerce
CPA.

The eight problems
that keep online sellers up at night.
Every e-commerce founder we onboard arrives with at least three of these. We’ve built a practice around fixing all eight — at one fixed monthly fee.
True COGS tracking
Landed cost per SKU — freight, duties, storage, returns. The number your “margin” is hiding.
Inventory management
SKU-level tracking across warehouses and 3PLs. Know what you own, where it sits, what it cost.
Cash flow projections
Rolling 13-week forecast. See the dip before it happens, not after the wire bounces.
Actual profit visibility
Channel-level P&L. Which platform makes money, which one is bleeding ad spend.
Sales tax nexus
Track economic thresholds in all 50 states. Register, file, remit — before notices arrive.
Marketplace reconciliation
Amazon payouts split into sales, fees, refunds, FBA, ads. No more “Amazon fees” black box.
Payroll & contractors
Multi-state W-2s, 1099 contractors, S-corp owner comp. Filed correctly, on time, every time.
Taxation & planning
Federal, state, multi-entity returns. Quarterly estimates that don’t surprise you in April.
Your channels in.
Clean books out.
We integrate every channel you sell on with the software stack that actually moves the needle for online sellers. No manual entry, no spreadsheet duct tape.

Four practices,
one obsession: your unit economics.
Most accountants treat your store like a service business. We don’t. Inventory, channel fees, returns, ad spend, and chargebacks are the actual game — and that’s what we measure.
Accrual-based monthly close
Tied out to Shopify, Stripe, Amazon, and your bank — not just QuickBooks. You get a real P&L by channel by the 10th of every month.
Federal, state, sales tax, nexus
Multi-state nexus tracking, sales tax filings across Avalara/TaxJar, plus federal returns built for inventory-heavy businesses.
CFO-level cash flow & forecasting
13-week cash flow models, SKU-level margin reviews, inventory turn analysis, and quarterly strategy sessions with a partner.
Books in chaos? We do rescues.
Three years of mismatched COGS, untracked inventory, missing 1099s — we untangle it and hand you back clean financials.
R&D credits & tax incentives
Custom packaging, proprietary blends, software dev — many DTC brands qualify for R&D credits and don’t know it. We find them.
Quality of earnings & due diligence
Selling to a private equity roll-up or aggregator? We get your numbers buyer-ready so you don’t lose value at the table.
Every month, you receive
eleven specific deliverables.
No vague “monthly bookkeeping.” Below is exactly what hits your inbox, the day it arrives, and what each report tells you. Same package whether you’re $50k/month or $5M/month — only the line items get bigger.
Channel-level P&L statement
Revenue split by every channel you sell on. COGS calculated at true landed cost. Marketplace fees broken out by type so you see what Amazon, Shopify Payments, and TikTok actually take. Contribution margin per channel — the number that tells you where to spend the next dollar.

From “we need a CPA” to your first
clean close — in 14 days.
Most accounting firms take 6–8 weeks to onboard a new client. We do it in two, because we’ve built a process around e-commerce specifically — not retrofit a generic small-business workflow.
The free discovery call.
A 30-minute video call with a senior partner — not a salesperson. We ask about your channels, your revenue mix, your tech stack, your tax structure, and the three things that are stressing you out about money. We listen. We tell you whether we’re the right fit. If we’re not, we’ll refer you to someone who is.

- Identify the 3 fixes that would move the needle most
- Walk you through how we’d structure your engagement
- Honest answer on whether we can help — no pressure

Within 48 hours of the call, you get a written proposal with a flat monthly fee — no hourly billing, no “we’ll add it up at the end.” The proposal lists every service we’ll deliver, the cadence, the tools we’ll use, and exactly who on our team handles what. You e-sign the engagement letter when you’re ready.

The kickoff meeting.
You meet your dedicated bookkeeper, tax lead, and account manager — the three people who will actually do your work.

- Meet your 3-person dedicated team — name, face, role
- Set up secure portal for documents and reports
- Confirm your monthly close timeline and report format
- Schedule recurring quarterly tax planning checkpoints
Setup, migration, and cleanup.
We connect your channels (Shopify, Amazon, Walmart, etc.) to your accounting software, rebuild your chart of accounts around e-commerce conventions, configure SKU-level inventory tracking, and reconcile any backlog. If you have months or years of messy books, we fix them now — not piecemeal as we go.

Your first clean close.
By day 14, you receive your first true e-commerce P&L: revenue split by channel, COGS at landed cost, marketplace fees broken out by type, and contribution margin per channel. We walk you through it on a 30-minute video call, answer questions, and leave you with a printable executive summary you can share with investors, lenders, or your spouse.

Before LedgerCPA, our books were a graveyard of QuickBooks dumps. Three years of “Amazon fees” lumped into one expense account. Returns hitting revenue. Inventory carried at landed cost in some months, FOB in others.
They rebuilt our chart of accounts around channels, fixed three years of broken COGS in five weeks, and gave us a clean trailing-twelve-month financial statement that the acquirer’s due diligence team couldn’t poke a single hole in. The book quality alone defended a $2.4M valuation premium. Worth ten times what they cost.
We were growing 60% year over year and somehow making less money than the prior year. Couldn’t figure out why. Our old accountant kept saying “the books look fine.” They were fine — they just weren’t telling the truth.
LedgerCPA built us a SKU-level contribution margin report and showed us our four best-selling ASINs were actually losing money once you allocated FBA storage, long-term storage fees, and the new inbound placement service. We discontinued two SKUs, repriced one, renegotiated freight on another. Margins went from 12% to 29% in two quarters. They paid for themselves in the first week.
We crossed the economic nexus threshold in seven states without realizing it — Texas, Florida, California, Illinois, Pennsylvania, Washington, North Carolina. Nobody had been watching. Our first three quarters with LedgerCPA involved a lot of catching up.
They registered us in all seven, filed back returns under voluntary disclosure agreements, negotiated three out of four penalty waivers, and set up automated nexus tracking so this never happens again. The total back-tax exposure was about $48k. Without VDAs and a clean filing position, penalties and interest would have pushed that past $200k. I sleep at night now.
Let’s see if your books
are telling the truth.
A free 30-minute call. No pitch, no upsell. Bring a recent P&L (or don’t) and we’ll tell you the three things we’d fix first.
