The Only Shopify Bookkeeping Checklist You Need
June 18, 2026 · 8 min read · Bookkeeping
Here's the thing about Shopify bookkeeping: it's not hard. It's just tedious, detail-oriented, and easy to procrastinate on — until tax season hits and you're staring at a mess of uncategorized transactions and missing receipts.
This checklist takes the guesswork out of it. Whether you do it yourself or hand it off, these are the exact tasks that need to happen every month, quarter, and year to keep your books clean and your CPA happy.
Monthly Bookkeeping Tasks Monthly
These take 15-30 minutes if you're organized. If you're not, they take 3+ hours. (This is the pain point we solve.)
Reconcile Shopify payouts with bank deposits. Export your Shopify payouts report and match every payout to a bank deposit. Flag discrepancies (fees, holds, adjustments).
Categorize all transactions. Every expense goes into a category: COGS, advertising, software, shipping, fulfillment, etc. If you're using a spreadsheet, this means tagging every line item.
Review Shopify fees and app charges. Shopify takes its cut. Payment processors take theirs. Apps charge transaction fees. These add up to $500-2,000/month on a $50K store. Make sure you're tracking all of them.
Update your P&L. Revenue minus all expenses = your profit for the month. If you don't know your profit, you don't know your business.
Record returns and refunds separately. Returns reduce revenue. But return shipping costs, restocking fees, and damaged goods are separate expenses. Track them independently.
Review ad spend by platform. Meta, Google, TikTok — know what you spent and what each platform returned. This feeds into your unit economics.
Save receipts for any out-of-platform expenses. If you paid for something with a personal card, or got a bill from a freelancer, record it. Missing deductions at tax time = overpaying.
Quarterly Tasks Quarterly
Review your margin trends. Are your margins shrinking? Growing? Stagnant? Compare this quarter to the last. If margins are dropping, find the leak (usually ad spend or COGS creep).
Check for duplicate or erroneous charges. App subscriptions you forgot about. Double charges. Overlapping tools. We've found $3,200 in duplicate charges for stores in a single quarter.
Estimate quarterly tax payments. If you're profitable (congrats), you likely owe estimated taxes. Calculate 25-30% of your profit and set it aside. Don't let this sneak up on you.
Update your Balance Sheet. What do you own (inventory, equipment, cash) vs. what you owe (loans, credit lines, unpaid invoices). This is the financial health snapshot most store owners never look at.
Annual Tasks Annual
Compile 12 months of financials for your CPA. Give your accountant a clean P&L, Balance Sheet, and Cash Flow for the year. The cleaner the books, the less you pay your CPA and the fewer mistakes on your return.
Review your chart of accounts. Add any new expense categories you discovered during the year. Remove ones you don't use. Keep it clean.
Analyze year-over-year performance. Revenue growth, margin changes, customer acquisition cost trends. This is where big decisions get made: raise prices, cut ads, change suppliers, launch new products.
File sales tax returns (if applicable). Nexus rules vary by state. If you're selling in multiple states, make sure you're collecting and remitting correctly.
5 Bookkeeping Mistakes That Cost You Money
1. Not reconciling Shopify payouts. Shopify holds, adjusts, and delays payouts. If you're recording revenue based on when orders ship instead of when you actually get paid, your books are wrong.
2. Ignoring app transaction fees. Recharge, Afterpay, Shopify Payments — each takes a cut. On a subscription-heavy store, this can be $500-1,000/month in fees you're not tracking.
3. Mixing personal and business expenses. If you're using one bank account for everything, your CPA will charge you more to sort it out. And you'll miss deductions.
4. Not tracking returns as a separate line item. Returns aren't just "lost revenue." They have costs: shipping, restocking, damaged goods. If you're not tracking return costs separately, you don't know your true return rate impact.
5. Waiting until tax season to look at your books. By then it's too late to fix anything. Monthly bookkeeping means no surprises. Annual bookkeeping means a panic attack in March.
