Frames invoices around billable time, fixed-fee milestones, retainers, reimbursable expenses, scope boundaries, and client approval workflow.
Enter your numbers first, then use the niche guidance below to interpret the output against independent consultants, boutique firms, professional services teams, and operations admins..
Consulting and advisory engagements often encompass fixed advisory retainers, deliverable milestones, or hourly project support. Clean line itemization establishes what work was performed during the billing cycle and gives client finance teams the documentation needed for prompt approval.
This manual invoice tool calculates line items as quantity times rate and applies a single optional tax rate across the entire subtotal. Retainers, milestone credits, or fee deductions must be calculated outside the tool and entered directly as final net line items.
The invoice calculates Subtotal = Σ(Quantity × Rate). A single user-entered tax percentage applies across the complete subtotal: Total = Subtotal × (1 + Tax Rate). Because the tool does not feature automated milestone tracking, retainers, or negative discount lines, consultants should calculate net deliverable fees or applied retainer balances externally and input the resulting billable amount directly.
A consultant bills a client for a completed strategic roadmap workshop deliverable. Having externally agreed to a fixed workshop fee of $3,500 with zero applicable sales tax, the consultant creates a single clean line item.
The invoice shows a single deliverable line of $3,500.00 with a $0 tax charge, producing an invoice total of $3,500.00. Payment wiring instructions and scope references are placed in the invoice notes section.
Interpretation assumptions: All amounts and tax percentages in this example are illustrative. The tool applies one user-entered tax rate to the entire subtotal. Confirm the actual tax treatment before issuing an invoice; mixed taxable and exempt items need a billing system that supports those rules.
Yes. Enter a positive fractional quantity such as 0.5 or 1.25 and the agreed rate.
No. Calculate the balance or prorated charge separately, then enter the amount due as a line item. Create and send each later invoice manually.
No. One entered percentage applies to the whole subtotal. Use a billing system that supports your actual tax rules when line items differ.
