E-Commerce Bookkeeping in Portland, OR
Hollis & Marsh keep the books for online sellers — real COGS, clean channel reconciliation, and reports that show what's working across Shopify, Amazon, and everywhere you sell.
Bookkeepers Who Actually Speak E-Commerce
Hollis & Marsh started in 2019 when our founders — both former online sellers — got tired of watching generalist bookkeepers butcher e-commerce books. Amazon fees in the wrong place, inventory ignored, channels never reconciled. So we built a firm that does one thing.
Today we keep the books for 150+ online brands and have reconciled over $80M in GMV. We know A2X, we know nexus, we know why your Shopify payout never matches your sales — and we turn all of it into clean books and reports you can actually run your brand on.

Frequently Asked Questions
Why hire an e-commerce specialist bookkeeper?
Online selling breaks the rules generalist bookkeepers learned. Platform fees, refunds, inventory, COGS, and multi-state sales tax nexus all behave differently. A specialist gets these right the first time — so your margins and reports are actually true.
Which platforms do you support?
All the major ones: Shopify, Amazon (FBA and FBM), Etsy, TikTok Shop, WooCommerce, and wholesale channels. If you sell across several at once, that's exactly what we're built for.
What is A2X and do I need it?
A2X is the industry-standard tool for reconciling e-commerce payouts to your accounting software. It's how we make your Shopify or Amazon deposits match your actual sales, fees, and refunds. We set it up and manage it as part of our service.
Can you handle sales tax nexus?
Yes. We monitor where your sales have triggered economic nexus across states and keep your multi-state sales tax obligations tracked and compliant — one of the trickiest parts of selling online.
How much does it cost?
One flat monthly fee based on your channels, order volume, and complexity — quoted up front with no hourly surprises. Cleanup and onboarding are scoped separately. Your assessment is free.
Do you only work with Portland businesses?
We're Portland-based but work with online brands nationwide — everything runs in the cloud, so your location doesn't matter. Most of our clients we've never met in person, and the service is identical.
