Frequently Asked Questions

Itemise phases like discovery, concept design, prototyping, and final handover as separate line items. Include the service period or milestone date in descriptions. Clear phase billing helps clients approve quickly and reduces scope confusion.

Yes, invoice retainers as a single line with the covered period and what is included, such as hours or deliverables. Add separate lines for out-of-scope work if needed. This keeps billing transparent and predictable.

If you are VAT registered, add VAT at your rate and show the VAT amount clearly, including your VAT number. Keep consistent invoice details for reporting. If not registered, do not charge VAT.

Add revisions as separate line items with a clear rate, such as per hour or per round. Include a short note on what changed. Making revisions visible reduces disputes and speeds approval.

Track software subscriptions, prototyping materials, travel, and contractor costs. Keep receipts linked to the period or client. Reports help you understand profitability per engagement.
