Built for the brands we know best

- Brands with inventory spread across FBA, a 3PL and a warehouse
Everything the monthly close needs
Settlement reconciliation
Each settlement unbundled into product sales, shipping credits, referral fees, FBA fees, storage fees, refunds, reimbursements and advertising, matched to the deposit.
FBA inventory
Inbound shipments, inventory at Amazon, removals, lost and damaged reimbursements, and COGS on fulfillment.
Marketplace facilitator tax
Tax Amazon collects and remits separated from tax you collect elsewhere, so nothing is double-counted or missed.
Advertising and promotions
Sponsored ads, coupons and Lightning Deals booked where they belong so ACOS and contribution margin are visible.
Multi-channel close
Amazon next to Shopify, Walmart, TikTok Shop and wholesale, in one set of financials.
Monthly financials
Profit and loss by channel, balance sheet and cash view by the 15th of the month, often sooner.
From first call to a clean monthly close
The same process for a $1M Shopify store and a $95M multi-channel brand; only the volume changes.

Before you book
Why is my Amazon deposit so much smaller than my sales?
A settlement nets out referral fees, FBA fees, storage, refunds, advertising and reserves before Amazon pays you. Booking gross sales and each deduction separately is the only way to see your real Amazon margin.
Do I owe sales tax on Amazon sales?
In almost every state Amazon collects and remits it as a marketplace facilitator. You still need to book it correctly and register where your own channels create nexus; we separate the two.
How do you track inventory in FBA?
From Amazon's inventory and reimbursement reports, reconciled monthly to your purchase records and your 3PL, so ending inventory and COGS are right.
Can you handle Amazon and Shopify together?
Yes. Most of our Amazon clients also sell on Shopify; both are in the same monthly close with margin by channel.
What does Amazon bookkeeping cost?
From $595 a month on cash basis and $995 on accrual, depending on settlement volume, channels and clean-up needs.
