From King Street boutiques moving high-end fashion, home goods, and jewelry to Lowcountry Shopify and Amazon brands shipping nationwide — Charleston retail runs on multi-channel sales, inventory tracking, and sales-tax economic nexus across states. We handle the books behind both the in-person register and the online cart.
No setup fees · Cancel anytime · Dedicated bookkeeper
Whether you're selling online, in a store, or on marketplaces — we understand how retail finances actually work.
Shopify, WooCommerce, and direct-to-consumer brands need COGS tracking, platform fee reconciliation, and multi-channel consolidation.
Physical stores with POS systems, inventory, and vendor relationships have their own bookkeeping demands — especially when combined with an online presence.
Marketplace platforms take fees, hold reserves, and pay out on varying schedules. Reconciling payouts against sales is a full-time job — unless you have us.
E-commerce and retail businesses face financial challenges that general bookkeepers routinely miss. Here's what we hear from nearly every new client.
Knowing your true cost of goods sold across products, variants, and channels is the difference between a profitable product line and one that's quietly losing money.
Shopify, Amazon, PayPal, Stripe — every platform takes a cut, plus processing fees, plus monthly subscriptions. Without tracking it all, your margin analysis is useless.
Selling in multiple states means navigating different sales tax rules in each one. We monitor your nexus exposure and make sure your records are ready for compliance.
Shopify says one number. Amazon says another. Your bank account says something else. We consolidate every channel into one clean monthly picture.
Every Tides plan includes all seven core services. E-commerce and retail clients get specific treatment for COGS tracking, multi-channel reconciliation, and inventory cost management.
Every account reconciled, every transaction categorized, every month — without exception. You receive a clean P&L and balance sheet with COGS broken out so you always know your true margins.
Monthly reports showing revenue, COGS, gross margin, and operating expenses — so you can see exactly where your business stands.
Every business account and credit card matched and verified each month. No mystery charges. No unresolved transactions. No surprises.
We track vendor payments, supplier invoices, and outstanding balances so your cash flow stays healthy and nothing gets missed.
Months or years behind? We clean it all up before we start your regular monthly service — no matter how far back the backlog goes.
If you have employees, we coordinate payroll processing and keep your tax filings clean and on schedule.
"I had no idea how much Shopify and Amazon fees were eating into my margins until Tides laid it all out. Total game changer."
Questions we hear from retail and e-commerce business owners before they sign on with Tides.
Charleston's retail economy doesn't fit one mold. It's the boutique on King Street and the Shopify brand shipping from a North Charleston warehouse — often the same owner running both. We work with sellers across Charleston County who need books that handle that complexity without flattening it.
King Street and the surrounding downtown corridor remain one of the most concentrated brick-and-mortar retail districts in the Southeast — high-end fashion houses, home and garden boutiques, jewelers, and gift shops drawing both locals and the city's steady tourism flow. The bookkeeping reality there is hands-on: daily POS reconciliation against merchant deposits, gift-card liability carried on the balance sheet long after the sale, seasonal inventory swings tied to tourism peaks, and product-level COGS that has to be tracked across hundreds of SKUs. Miss a reconciliation and the margin picture quietly drifts.
The other half of Charleston retail lives online. The city's design and lifestyle culture has bred a real Shopify, Amazon, and Etsy seller community — apparel brands, home goods, candles, coastal accessories, paper goods — many born out of the same neighborhoods that built the in-person boutique scene. These sellers ship nationwide, which means South Carolina sales tax is just the starting point: economic nexus thresholds get tripped in a dozen other states, and someone has to track collected tax by jurisdiction. On the inbound side, the Port of Charleston gives local brands a real cost advantage for imported stock, but landed-cost accounting on container freight has to be handled correctly or COGS gets ugly.
Most of the Charleston retail owners we talk to aren't running just one channel — they're running the in-person shop, a Shopify storefront, an Amazon listing, a wholesale arm into other Lowcountry stores, and maybe a few pop-ups during peak season. Each channel has its own merchant processor, its own fee structure, its own payout cadence, and its own reconciliation pattern. The books only work when every channel ties cleanly back to the bank, COGS is allocated across them honestly, and the monthly P&L shows what's actually profitable versus what just looks busy. If that's the world you're operating in across Charleston, that's exactly what we're built for.
