Merge Invoice PDFs

Managing invoices across vendors, clients, and billing periods means dealing with dozens — sometimes hundreds — of individual PDF files. Accountants, bookkeepers, and business owners spend unnecessary time hunting through scattered invoice files when tax season arrives or when a client requests consolidated billing records. Merging invoices into a single PDF solves this problem instantly.

Coda One's PDF Merger lets you combine all your invoice PDFs into one organized document directly in your browser. Drag and drop your invoice files, reorder them by date or vendor, and download a single merged PDF in seconds. Files are processed in your browser with pdf-lib during merging, so invoice content is not uploaded to our servers in that step.

The reorder feature is especially useful for invoices: arrange by chronological order for auditing, group by vendor for accounts payable review, or sort by amount for financial reporting. Whether you're preparing quarterly expense reports, consolidating client invoices for payment, or archiving monthly billing records, this tool handles the job without touching your data. Works with invoices from any accounting software — QuickBooks, Xero, FreshBooks, Wave, or manually created PDFs.
