Accounting for E-Commerce Sellers
Online sellers get paid in lump-sum payouts with fees, refunds and ad spend already taken out, which makes profit hard to see. Northlane Financials reconciles every payout, tracks inventory and cost of goods sold, and prepares your business tax return from accurate numbers.
