Omnichannel selling: one stock count for the store, the website and Amazon

The real problem with selling in more than one place

Adding a website or a marketplace is easy. Keeping the stock count honest afterwards is not. A product sells online at the same moment the last unit goes out the door in-store, and now there is a refund, an apology and a bad review. Each channel also reports sales, fees and tax differently, which makes the accounting harder than the selling.

Omnichannel selling works when there is one inventory and one record of what sold where. SeroPOS holds the stock and the channel connections. SeroBooks handles the accounting side, especially for Amazon, where settlements, fees and tax rules need more than a lump-sum deposit. Each piece does one job, and together they keep the counts and the books in step.

Channels SeroPOS sells through

At the counter, SeroPOS handles barcode scanning, variations, modifiers, discounts, loyalty and returns. The same product catalogue powers a built-in online store with cart and checkout, and orders come into a web-order queue so staff can pick, pack or prepare them. Restaurants can switch between dine-in, take-away and delivery modes.

QR self-ordering lets guests order from a table or a pickup line on their own phone, and payments run through Stripe or PayPal. For food businesses, SeroPOS offers delivery-platform menu and order management, with direct Uber Eats integration rolling out in Canada. Email and SMS receipts follow the customer whichever way they ordered, and every order lands in the same sales reports.

Shopify and WooCommerce alongside the store

Many retailers already run a Shopify or WooCommerce site and want the shop floor to match it. SeroPOS syncs two-way with Shopify, so products and stock stay aligned between the website and the counter. WooCommerce sync covers stores built on WordPress. That means the website stops overselling items the store has already sold.

Note that Shopify and WooCommerce sync are SeroPOS features. SeroBooks does not connect to Shopify directly, so the store’s catalogue and stock live in SeroPOS. Businesses that sell online and want full accounting can sync SeroPOS into SeroBooks, QuickBooks Online or Xero, so channel sales reach the ledger without manual entry.

Amazon on the shelf and on the P&L

SeroPOS syncs with Amazon alongside the store. The accounting is where Amazon gets complicated: one settlement can hold sales, referral fees, FBA fees, storage, ads, refunds and reimbursements. Recording only the net deposit hides what each sale really earned. SeroBooks for Amazon, at $150 a month, posts each settlement to the ledger with fees itemised and returns and reimbursements tracked.

It handles Amazon.ca, Amazon.com and Amazon.com.mx, splits marketplace-facilitator tax so you do not remit tax Amazon already collected, and invoices on the order day. Amazon Ads spend for Sponsored Products, Brands and Display shows on the P&L with TACOS, and inbound shipments, forecasting and replenishment help plan stock. SeroBooks for Amazon is described as replacing a separate settlement tool, profit dashboard and planning spreadsheet.

• Settlements posted with fees itemised
• Marketplace-facilitator tax split
• Amazon Ads and TACOS on the P&L
• Returns, reimbursements and storage fees
• North America only: .ca, .com, .com.mx

Choosing a setup

A shop or restaurant adding online orders can start with SeroPOS alone, from $29.99 a month on Standard. Pro at $49.99 a month adds QuickBooks and Xero sync, advanced reporting and recipe management. Both come with a 14-day free trial and no credit card. Chain store management is included on both plans, so adding a second location later does not require switching products.

A brand that sells mostly on Amazon with some retail will usually want SeroBooks for Amazon for the accounting, plus SeroPOS for the counter. If SeroBooks is already your accounting system, the Amazon module is a $100 a month add-on. Book a demo with your channel list and we will show how the pieces connect.
