Common questions
Quick answers.
- What does Wrenbase Invoicing do?
- Quote a client, turn the quote into an invoice, send it, and chase down what's late. All in one place. You're not jumping between a quote tool, an invoice template in Word, and a separate way to track payment.
- Today my invoices live in a spreadsheet. What changes?
- Instead of tracking who paid in a row, your invoices and payments live in Wrenbase. You see what's outstanding without filtering. Reminders happen automatically. And if you've got past invoices in a spreadsheet today, drop the file in and Wrenbase will import the history.
- How do my clients pay?
- Card and ACH payments through Stripe are rolling out now. Once they're live for your account, every invoice carries a Pay button and the money settles to your bank on Stripe's standard timeline. Today you can send invoices, track what's outstanding, and mark them paid however the money actually arrives.
- How do I sign in? Is there a password?
- No password. We email you a sign-in link. Tap it, you're in. Nothing to remember, nothing to reset, nothing to lose.
- Can my invoices carry my logo and branding?
- Yes. Upload your logo on the free plan and it shows up on every invoice you send. Paid plans add custom colors and theme. The invoice your clients see carries your brand, not ours.
- Can I send recurring invoices?
- Yes. Set the schedule once, pick the client, the amount, and the day of the month. Wrenbase sends it every cycle. Auto-send for clients you trust. Hold-for-review for the ones you don't.
- Does Wrenbase do automatic reminders?
- Yes. Gentle before the due date, firmer after. You set the tone, you edit the words if you want, and the reminders go out until the invoice is paid or you stop them.
- Can I bill in different currencies?
- Yes. Twenty-plus currencies including USD, EUR, GBP, INR, BRL, JPY. You pick the currency per invoice. Each one stays in its original currency end to end. We don't convert anything for you.
- Do I need accounting software too?
- No. Wrenbase handles the work of sending invoices, getting paid, and tracking what's still owed. If your accountant wants the numbers in QuickBooks or Xero at tax time, you can export to them. Wrenbase isn't trying to replace your accountant. It's trying to replace the spreadsheet and the four tools that came before them.
- Can I group invoices by project?
- Yes. Tag an invoice or quote to a project when you create it, or link it later from the project's Revenue tab. The project's P&L updates the moment the invoice is paid: billed, collected, and margin, per engagement.
