FAQ

Frequently Asked Questions

The platform connects directly to your Excel spreadsheet and automatically converts each row of data into a fully formatted, professional invoice. Simply upload your spreadsheet, confirm your settings, and the system generates all invoices instantly — no manual formatting or copy-pasting required.

Not necessarily. During setup, the platform is configured to match your existing spreadsheet structure and workflow. In most cases your current format can be used with minimal or no changes, making the transition as smooth as possible.

Setup is typically quick once your spreadsheet format and preferred invoice template have been confirmed. Most clients are up and running within a short onboarding session — there is no lengthy installation process or technical configuration required on your end.

Yes. Your spreadsheet data is processed locally within your browser and is not uploaded to or stored on any external server. Your contractor and payment data stays entirely within your control at all times.

There is no limit. Whether you need to generate 10 invoices or 10,000, the platform handles them all in a single run. Upload your spreadsheet, hit generate, and every invoice is produced and packaged into a downloadable zip file in seconds — regardless of volume.

The platform accepts Excel files (.xlsx) and CSV files (.csv). If your current payment or timesheet data lives in either of these formats — which covers the vast majority of agency and umbrella workflows — you can use it directly without any conversion or reformatting.

Yes. The subscription covers your organisation, not individual seats. Any member of your team can access and use the platform from their own browser — there is nothing to install and no per-user licensing to worry about.

Nothing needs to happen — because nothing is stored. Since all processing takes place locally in your browser, we never hold any of your data on our servers. If you cancel, there is no data to delete, no account to wipe, and no offboarding process. You simply stop using it.

Absolutely. You can upload your company logo, enter your business name, address, VAT number, and contact details, and they will appear on every invoice generated. You can also choose from four professionally designed invoice layouts to find the one that best fits your brand.
