Spending hours every month sorting through transactions by hand is one of those founder tasks that feels like progress but mostly just delays the close. When categorization is set up properly with automated rules for your recurring vendors, your books stay current in the background and your financial statements are ready when you actually need them.
TLDR:
First, go to your “Transactions” page.
You'll see your transaction history, a list of transactions we've pulled from your bank accounts, company credit cards (Ramp, Brex), and Stripe account. If your bank doesn't support a direct connection, you can also upload PDF statements and Puzzle parses the transactions automatically.
Next, click on a transaction’s category to begin classifying it.
From there, Puzzle converts these detailed transactions into accurate cash-basis financial statements for your company.
Rules can help you automate categorization, saving you time every month.
Let's say you have a recurring transaction, like a monthly invoice from a SaaS vendor.
To avoid having to make the same categorization every month, you set up a rule that says every new transaction matching this description is labeled under the Software & Subscriptions category. After making a rule once, you'll never have to categorize that type of transaction again. Rules can match on merchant name, description keywords, or transaction amount ranges, so a single rule can cover every charge from your payroll processor, your cloud hosting provider, or your legal retainer at once.
Puzzle's automation learns from the categories you set and creates smarter automated rules to generate category suggestions. For example, if you've categorized several charges from the same payroll processor under Payroll Expenses, Puzzle recognizes the pattern and proposes a rule to cover future charges from that merchant automatically. You review the suggestion once, confirm it, and every subsequent payroll charge is handled without any manual input. The same logic applies across vendors: cloud hosting, legal retainers, insurance premiums. Each confirmed suggestion tightens the coverage, so over time the share of transactions that need any human review shrinks closer to zero.
Whether you’re filing taxes, raising your Series A, or just trying to understand your business better, accurate financial records are an absolute must. Without detailed bookkeeping (including categorized transaction histories), your records become far less reliable.
Inaccurate categorization can lead to:
| Without accurate categorization | With accurate categorization on Puzzle |
|---|---|
| Incorrect insights into business health | Real-time burn rate and runway visibility |
| Inaccurate investor reporting | Reliable financial statements ready for due diligence |
| IRS exposure and audit risk | Clean, categorized records that substantiate every deduction |
| Hours of manual work each month | Automated rules handle recurring transactions after one setup |
| Month-end close takes weeks | Well-configured rules routinely cut close times to days |
In the end, categorizing your transactions on Puzzle is both low-lift and high-return.
Spending a few minutes each week to categorize transactions or set up rules can save you hours per month and increase the accuracy of your financial data, which lets you make better decisions for your business.
Every dollar your startup spends flows through a transaction. When those transactions are categorized correctly and categorized fast, Puzzle converts them into live financial statements the moment they clear. That means your burn rate and runway update daily, not at month-end when it's too late to act.
For seed-stage founders, that cadence matters. You don't need to wait for a bookkeeper to close the books or export a spreadsheet to know where you stand. Connect your bank accounts, credit cards (Ramp, Brex), and payment tools (Stripe) and Puzzle pulls the transactions automatically. Set up categorization rules for your recurring vendors once, and your burn dashboard stays current without any manual work.
The result: runway visibility in hours, not weeks, so you can make hiring, vendor, and fundraising decisions on real data, not last month's snapshot.
Two overlapping pressures make accurate transaction categorization a higher-stakes task right now.
First, the IRS has been steadily tightening its digital recordkeeping guidance for small businesses and startups. Clean, categorized transaction histories are increasingly the baseline expectation, and not a nice-to-have, when substantiating deductions or responding to an inquiry. Disorganized books don't just slow down your accountant; they create exposure.
Second, AI-native accounting tools have reset what "good" looks like. If your categorization is still largely manual, you're likely spending far more time on it than teams using automated rules and AI suggestions. Based on Puzzle customer data, teams with well-configured rules routinely close in days, not weeks, a gap that has only grown as automation tooling has matured.
Setting up rules in Puzzle, even a handful that cover your most recurring vendors, is one of the highest-return 20 minutes you'll spend this quarter. Teams that go further and automate their month-end close routinely cut close times from weeks to days.
Yes, and that's exactly what Puzzle's automation is designed for. Once your bank accounts and cards are connected and your rules are configured, Puzzle's AI categorizes new transactions in the background as they arrive. You don't need to log in daily, chase uncategorized items, or run a manual reconciliation at month-end.
Puzzle learns from every categorization you make and applies that logic automatically to matching transactions going forward. For most recurring vendors, such as your SaaS subscriptions, payroll processor, and cloud infrastructure, the AI handles categorization without you touching it. The closer your rules are to covering your full transaction volume, the closer your books stay to closed at all times.
That's a different model from legacy tools like QuickBooks or Xero, which still expect you to review and confirm a large share of transactions by hand. Puzzle built AI-native automation from day one, and not a suggestion layer bolted onto manual workflows, so the month-end close happens continuously instead of as a painful sprint. See how AI bookkeeping automation vs. judgment plays out in practice.
When categorization runs in the background, your financials stop being a monthly fire drill and start being something you can actually rely on. Your runway is current, your records are clean, and you spend less time chasing down transactions before every close. That kind of visibility makes hiring calls, vendor decisions, and fundraising conversations a lot easier to have with confidence. Book a demo to walk through what automated categorization looks like for your specific setup.
When you connect a bank login that includes both personal and business accounts, Puzzle lets you select which accounts to sync so personal transactions never enter your books. If a transaction is imported incorrectly, you can exclude or delete it directly from the Transactions page, and it won't affect your categorization rules or financial statements going forward.
Yes. If your bank doesn't support a direct connection, you can upload PDF bank statements and Puzzle will parse and import the transactions. From there, the same AI-assisted categorization and rules engine applies, so even without a live feed, your books stay organized and your financial statements stay current.
Yes. Connect your payment processor (Stripe is natively supported) and Puzzle pulls in your revenue transactions automatically, categorizes them, and reflects them in your P&L in real time. You can track gross revenue, cost of goods sold, and profit margins without manual data entry, giving you an accurate, up-to-date picture of your business performance.
Puzzle updates your burn rate and runway dashboard as transactions clear and sync, so your cash flow view reflects what's actually in your accounts. For transactions that haven't come through yet (pending payments, wire transfers in transit), Puzzle doesn't guess: it shows you the real cleared balance and flags the gap so you're never making decisions on phantom cash.
Puzzle's AI goes beyond answering questions. It can take direct actions in your books: splitting transactions across multiple categories, flagging potential fixed assets for your review, and pulling mini P&L snapshots on demand. Think of it as an accounting agent that can both explain your financials and make targeted changes, with you staying in control of what gets finalized.
