What bookkeeping tasks should be done weekly vs monthly?
The distinction comes down to this: weekly tasks keep you current and catch problems before they compound. Monthly tasks close out the period and give you the full financial picture.
Weekly tasks should include reviewing and categorizing transactions as they come in. Don’t let a week’s worth of bank activity pile up without knowing what each charge was for. This is also when you follow up on unpaid invoices, review upcoming bills, and make sure your cash position looks healthy. If you’re coding expenses to jobs or projects, do it weekly while you still remember what each purchase was for.
Receipt management belongs on the weekly list too. Take photos, upload them to your accounting software or storage system, and match them to transactions. Waiting until month-end means faded receipts and forgotten context. The IRS doesn’t accept “I think that was for office supplies” as documentation.
Monthly tasks start with full bank and credit card reconciliation. Compare every transaction in your accounting software against your actual statements. This catches duplicate entries, missed transactions, and potential fraud. You should also reconcile any payment processors, PayPal accounts, or other cash sources.
Generate your financial statements monthly and actually look at them. Your profit and loss shows whether you made money. Your balance sheet shows what you own and owe. Review your accounts receivable aging to see who hasn’t paid. Review accounts payable to make sure nothing slipped through.
Sales tax calculation and filing prep happens monthly for most businesses, even if you only file quarterly. Sales tax management gets messy fast if you’re scrambling to figure out three months of transactions at once. Calculate it monthly and the quarterly filing takes minutes instead of hours.
If you run payroll, review those journal entries monthly to make sure wages, taxes, and benefits are hitting the right accounts. Product businesses should do some form of inventory review monthly to catch discrepancies between what the system says you have and what’s actually on shelves.
The weekly time investment is small. Maybe 30 minutes to an hour depending on transaction volume. Monthly closing takes longer but shouldn’t be a major project if you’ve kept up with weekly tasks. Businesses that skip weekly work end up with monthly closes that take all day and still miss things.
Some businesses need more frequent attention. Restaurants with daily cash deposits might need daily reconciliation. High-volume e-commerce stores might need transaction review every few days. Adjust based on how many transactions flow through and how quickly problems could escalate.
The goal is avoiding the scramble. Business owners who only touch their books quarterly or at tax time spend hours reconstructing what happened months ago. Phoenix area bookkeeping services exist because that scramble is expensive and stressful. A consistent weekly and monthly rhythm keeps you in control of your numbers instead of reacting to them.

How often should my books be updated?

Read answerWhy is my e-commerce profit and loss statement inaccurate?
E-commerce P&Ls are often wrong because of inventory costing problems, miscategorized marketplace fees, or timing issues with returns. The most common culprit is Cost of Goods Sold that doesn't reflect actual product costs including landed costs like shipping and duties.

Start with the oldest unreconciled month and work forward chronologically. Gather all your bank and credit card statements, then tackle one account at a time until you're current.
Read answerHow do I reconcile Amazon payouts with my bank account?
Amazon deposits a net payout that includes sales minus fees, refunds, and reserves. Use your Settlement Report from Seller Central to see what's inside each deposit and record the components separately in your books.
Read answerWhat documents do I need to catch up my bookkeeping?
Start with bank and credit card statements for the entire catch-up period. Add merchant processing reports, loan statements, and any receipts you have. A bookkeeper can work with incomplete records, but statements are the foundation.
Read answerWhy is my COGS wrong on my e-commerce profit and loss?
COGS errors in e-commerce usually come from how inventory is tracked. If purchases go straight to COGS instead of through an inventory account, or if your ending inventory balance is wrong, your cost of goods sold won't match reality.
