The Problem

Your competitor already automated this. It's your turn.

The same spreadsheet. The same contractors. Two entirely different mornings.

I The Weight
09:14
Open payroll. Reformat columns. Save a new version so you don't overwrite last week's.
09:47
Export the first batch. Rename the eighth PDF because the template called it "Invoice-Copy-Final-2."
10:22
Cross-check deductions against payroll. Find two errors. Re-export. Find one more.
11:08
Write the emails. Copy, paste, swap the name, swap the amount, attach, send.
12:41
Still sending. Missed lunch. Three contractors will chase you before five.

FAQ

Before you ask

Your spreadsheets are processed entirely inside your browser. No contractor names, bank details, or payment amounts ever leave your machine or touch our servers. The invoices are generated locally using JavaScript, which means there is nothing to intercept, store, or breach. We never see your data.

No. Upload any Excel or CSV file and our fuzzy column mapper will automatically detect and match your headers — contractor name, gross pay, deductions, bank details — regardless of what you have called them. No reformatting, no templates, no wasted time adapting your existing workflow.

There is no limit. Whether you have 6 contractors or 6,000, every invoice is generated in a single run and downloaded as a ZIP file. The entire process takes seconds, not hours. Your browser does the heavy lifting.

Yes. Upload your company logo, enter your business details, and choose from four professionally designed layouts — dark, corporate, branded, or minimal. Every PDF that reaches your contractors carries your identity, not ours.

After your invoices are generated, the AI writes a personalised email for every contractor — addressing them by name, referencing their specific payment amount, and matching the tone you select (formal, friendly, or neutral). You preview each email before sending. Nothing goes out without your approval.

Month to month. No annual lock-in, no cancellation fees, no notice period. You pay £299 per month and you can cancel from your dashboard at any point. If you cancel, you keep access until the end of your billing cycle.

Two ways. First, the live demo on this page lets you generate real invoices from sample data right now — no signup required. Second, every subscription starts with a 30-day free trial with full access to every feature. You will not be charged until day 31.

Every invoice run is logged with a timestamp, contractor count, and total value in a full audit trail that you can export as a PDF at any time. The system is designed to give you exactly the kind of documentation HMRC expects — clear records of what was paid, to whom, and when.

Most teams are generating invoices within five minutes of signing up. If you need a hand, request a demo and we will walk you through everything on a call. We also offer free onboarding support for your first invoice run to make sure your column mapping, branding, and email settings are exactly right.

Accounting software is built for bookkeeping. Initium Automate is built for one job: turning a payroll spreadsheet into hundreds of branded, personalised invoices and delivering them to contractors automatically. No chart of accounts, no reconciliation screens, no complexity. Upload, generate, send, done.
