Frequently Asked Questions

Either works. Fixed-price suits smaller builds, while milestones help for larger scopes. Simply Invoicing lets you itemise phases so clients know exactly what they’re paying for.

Add a retainer line for the month and list any extra hours or add-ons separately. This keeps scope clear and makes renewals easier for both you and the client.

Only if you’re VAT-registered and VAT applies. If so, your invoice should show VAT number, rate and amount. Simply Invoicing totals VAT and supports VAT-ready reporting.

Use due dates, statuses, and notes for purchase order references. That way you can follow up quickly and keep a clean audit trail.

Typical expenses include SaaS tools, hosting, domains, hardware, contractor costs, and training. Tracking these alongside invoices helps you understand profitability and prepare reports.
