このガイドを信頼する理由

I have run my own books in Wave for three years and tested every feature here.

このチュートリアルは、ベンダーのスクリーンショットではなく、実際の作業経験に基づいています。

Wave lets 中小企業 owners create beautiful invoices, accept online payments, and make accounting easy.

But most people only ever send an invoice and stop there.

Knowing how to use Wave properly gets rid of hours of manual 簿記.

That frees you to focus on the work that actually pays.

This guide shows you every feature, step by step, with pro tips.

Waveを使い始める

Do this one-time setup before touching any feature.

約3分かかります。

The setup takes a bit of patience, then Wave keeps running on its own.

Here is what the first few weeks looked like for me:

それでは、各ステップを順を追って見ていきましょう。

ステップ1：アカウントを作成する

Go to Wave’s website and click Sign Up.

Use a business email, then set up your company profile with a logo and brand colors.

✓ チェックポイント: チェックしてください受信トレイ確認メールについて。

ステップ2：ダッシュボードにアクセスする

Wave runs in the browser.

iOSとアンドロイド apps handle receipts and invoices on the move.

ダッシュボードの画面は以下のようになります。

✓ チェックポイント: You should see cash flow and unpaid invoices on the home screen.

Step 3: Link Your Bank

Connect your business bank and credit card accounts under Banking.

Wave imports bank transactions automatically, which saves real time on bookkeeping.

✅ 完了: 以下の機能はすべてご利用いただけます。

Step 3: Match and Close the Month

Wave Proのヒントとショートカット

After three years in Wave, these are the tips I actually use.

キーボードショートカット

アクション	ショートカット
Save the open invoice	Ctrl / Cmd + S
Add a new invoice line	Tab from the last field
トランザクションを検索	Ctrl / Cmd + F
Print or save a report as PDF	Ctrl / Cmd + P

ほとんどの人が見逃す隠れた機能

Partial refunds: Send either a full or partial refund on any customer payment, straight from the payment record.
Google Sheets add-on: Import and export customers, products, and invoices in bulk instead of one at a time.
Estimates that convert: Create a project estimate, then turn it into an invoice once the client approves it.
Collaborator access: Share view-only or edit access with your accountant without handing over your password.

These small features are where Wave quietly beats pricier accounting solutions.

波に関するよくある間違いを避ける

Mistake #1: Mixing personal and business money

❌ 間違い: Running groceries and client payments through one bank account.

✅ 右: Keep personal and business finances separate from day one for clean project tracking.

Mistake #2: Typing in transactions the bank already sent

❌ 間違い: Manually entering expenses that also arrive through your bank feed.

✅ 右: Pick one source. Duplicate entries are the most common Wave error I see.

Mistake #3: Invoicing without online payments turned on

❌ 間違い: Emailing a PDF and waiting weeks for checks to clear.

✅ 右: Enable card, bank transfer, and Apple Pay so clients can pay in one click.

波のトラブルシューティング

Problem: Bank feed stopped importing transactions

原因： Your bank changed its login rules or the connection expired.

修理： Go to Banking, reconnect the account, then import the missing period manually.

Problem: Reconciliation will not balance

原因： A duplicate transaction or a payment recorded on the wrong date.

修理： Sort by amount, delete the duplicate, and check dates near the month boundary.

Problem: A client says the invoice link does not work

原因： The email landed in spam, or the invoice is still a draft.

修理： Confirm the invoice status is sent, then share the payment link directly.

📌 注記： If none of these fix your issues, contact Wave support.

よくある質問

Waveアプリはどのように動作しますか？

You link your bank and Wave imports transactions automatically. From there you categorize spending, send invoices, accept online payments, and track business finances.

Waveは初心者でも使いやすいですか？

Yes. Wave is built for small business owners with no accounting background. Most people send a first invoice within ten minutes of signing up.

Waveを無料で利用するにはどうすればいいですか？

Sign up for the Starter Plan at $0. You get invoicing, accounting, and reports free. You only pay processing fees when clients send payments.

WaveはQuickBooksよりも使いやすいですか？

For simple books, yes. Wave shows fewer menus and less jargon. QuickBooks offers more depth, which helps once you add inventory, payroll, or staff.

WaveアプリはIRS（米国国税庁）に報告義務がありますか？

Wave itself does not file your taxes. Payment processing may generate tax forms where thresholds apply. You still report income yourself using Wave’s reports.
