California e-commerce accounting that knows your real margin by channel.

Once a retailer’s combined sales of tangible personal property for delivery in California exceed $500,000 in the preceding or current calendar year (a sales-only threshold, no transaction count), it is engaged in business in California and in every district, and it collects district tax at the rate in effect where the property is delivered, not a flat statewide rate. Below that threshold, district tax follows the districts where the retailer has a physical presence. Registered marketplace facilitators are the retailer for the sales they facilitate; your direct sales are yours to handle.

Yes — it’s the core of the work. Amazon and Shopify pay out net of fees, refunds, reserves, and adjustments, so the deposit never equals the sales. We reconcile each channel (often via A2X or a similar tool) so deposits tie to sales, fees land in the right accounts, and the books are accurate from the first month.

By tying inventory and COGS to SKU and channel and pulling fees, shipping, returns, and chargebacks into the right places. A blended gross margin hides the products and channels losing money on every order; SKU- and channel-level contribution shows you which to grow and which to cut.

Possibly — each state with a sales tax sets its own economic-nexus threshold, so a growing seller can cross several, and inventory stored in another state’s warehouse, FBA included, can create physical nexus there. We keep your sales-by-state picture clear so a nexus review is fast; the determination and the multi-state registrations and filings are handled by your CPA or a sales-tax specialist.

Yes — your file, your data, in QuickBooks Online or hosted Desktop, with a senior bookkeeper assigned to your file, and every close reviewed by a Certified QuickBooks ProAdvisor before it reaches you. We connect to your channels and tools rather than locking you into proprietary software.

No. TechBrot does not prepare or file tax returns; we work with your CPA or EA. TechBrot is a bookkeeping and advisory firm — we keep the books CDTFA-ready and reconcile the liability, and your CPA or EA files the CDTFA return, determines nexus, and represents you in any audit.

If you hold a seller’s permit, generally yes — and then you deduct them. Under the Marketplace Facilitator Act, since October 1, 2019 a marketplace facilitator that is registered, or required to be, is the retailer for the sales it facilitates, so it is responsible for the tax on them. A seller that also sells directly, through its own site or in person, generally must register, reports its total sales on the return and claims the facilitated sales as an “other” deduction. CDTFA’s guide points to an agreement or other record showing the facilitator is registered and responsible for the tax, and says to obtain the facilitator’s seller’s permit or account number. In the books, marketplace and own-site sales sit in separate income accounts so the deduction ties to the marketplace’s reports, and the facilitated sales still count toward your $500,000 threshold.

The rate where the goods are delivered, once you are engaged in business in that district. A retailer whose combined sales for delivery in California exceed $500,000 in the preceding or current calendar year is engaged in business in every district, whether or not it has a physical presence there, and collects district use tax at the rate in effect at the delivery address. A smaller retailer is engaged in business only in the districts where it has a physical presence. In QuickBooks, that means sales tax is figured from the ship-to address on each order, never one statewide rate, and the liability is reconciled to the return’s district schedule every period.
