Admin, Member, or Accountant: Agency Billing Roles
Most agencies don't think about billing permissions until something goes wrong. A bookkeeper who only needed to pull a payment report ends up with full account access by default. A new account manager gets added the same way as the found...
How Invoice Auto-Numbering Prevents Duplicates
If you run a one person shop, you'll probably never think about this problem, because you're the only person who can ever click "save" on an invoice. The moment you add a second teammate who can also create invoices, though, a new questi...
Why Your Invoice Tax Total Is Off By a Penny
You add up the line items yourself, apply the tax rate you know is correct, and the number you land on is a cent or two different from what's printed on the invoice. Nothing was overcharged, nothing was miscalculated in any meaningful se...
Is It Safe to Put a QR Code on Your Invoice?
If you've thought about adding a QR code to your invoices, you've probably also seen a headline or two about "quishing" — QR code phishing — and wondered whether you'd be handing your clients a security risk along with your bill. That's...
Why Comment Threads Beat Email for Invoice Disputes
A client opens your invoice, looks at one line, and doesn't like what they see. Maybe it's a rate they don't remember agreeing to. Maybe it's a line item they don't recognize at all. Maybe the total is just higher than they expected and...
Building Reliable Integrations With Invoice Webhooks

Invoice Software for Agencies: Workspaces, Reports & API
Invoicing tools built for solo freelancers tend to break down in one of two ways once a small team is involved. Either everyone ends up with their own disconnected account, invoicing the same clients out of sync with each other, or the t...
Get Paid Faster: Client Portals, QR Codes & Partial Pay
Sending an invoice is the easy part. Almost any tool can generate a PDF with a total and a due date on it. The harder problem — the one that actually determines whether you get paid on time — is everything that happens after you hit send...
How to Track Billable Hours and Invoice Automatically
If you bill by the hour, there's a very specific kind of friction that happens once a month: you open your timer app, scroll back through a few weeks of entries, do some mental (or spreadsheet) math to group hours by client, and then ret...
Invoice Generator Features: The Full Platform Tour
Most people find Invoice Generator the first time they need exactly one thing: a clean PDF invoice, made fast, without signing up for a subscription to send a single bill. That part of the product hasn't changed. But the tool underneath...
Invoicing for Nonprofits and Grant-Funded Programs: What's Different
Most invoicing advice assumes a simple, two party transaction: you did work, a client owes you money, you send an invoice. Nonprofit invoicing frequently doesn't work that way. A single program might be funded by three different grants,...
