Invoice and Proposal Management for Consultants
Getting paid should be the easy part. Here's how to streamline proposals and invoicing so you can focus on client work.
Proposal Best Practices
Structure That Converts
- Executive Summary (What they get)
- Understanding (You understand their problem)
- Approach (How you'll solve it)
- Deliverables (Specific outcomes)
- Timeline (When they'll get it)
- Investment (Pricing)
- Next Steps (Clear CTA)
Pricing Presentation
Do: Present value before price Don't: Lead with numbers
Frame pricing in terms of ROI: "Investment: $5,000 for a system that will save you 10 hours/week (worth $15,000/year)"
Speed Matters
Send proposals within 24 hours of the discovery call. Momentum matters.
Invoicing Best Practices
Invoice Timing
| Project Type | When to Invoice |
|---|---|
| Retainer | 1st of month, due within terms |
| Fixed project | 50% upfront, 50% on completion |
| Hourly | Every 2 weeks or monthly |
| Value-based | Based on milestones |
Invoice Elements
Every invoice needs:
- Your business details
- Client details
- Invoice number (unique, sequential)
- Invoice date
- Due date
- Line items with descriptions
- Total amount
- Payment methods
- Terms and conditions
Payment Terms
- Net 15: For established clients
- Net 30: Standard
- Due on receipt: For new or small projects
- 50% upfront: For new clients or large projects
Getting Paid Faster
1. Make Payment Easy

2. Send Reminders
- 7 days before due

Frequently Asked Questions
How do I price my consulting proposals?
Value-based pricing typically works best. Calculate the ROI you'll deliver (time saved, revenue generated, costs reduced) and price at 10-20% of that value. For hourly work, research market rates for your expertise level, then add 20-30% for overhead and profit. Our consultant guide covers pricing strategies in depth.
What's the best payment terms for new consulting clients?
For new clients, always get 50% upfront before starting work. This protects you from non-payment and demonstrates client commitment. After 3-6 successful projects, you can offer Net 15 or Net 30 terms. For retainers, bill on the 1st with Net 15 terms.
How do I follow up on unpaid invoices without damaging relationships?
Use a friendly, professional escalation sequence: reminder 3 days before due, polite notice on due date, concern message at 7 days late, firm notice at 14 days, final notice at 30 days. Automating this through Dewx OPS Hub removes the awkwardness since reminders are "system-generated."
Should I use proposal software or just send PDFs?
Dedicated proposal tools offer tracking (know when clients view), e-signatures, and templates. But they add cost and complexity. For most consultants, a clean PDF or Google Doc works fine until you're sending 10+ proposals monthly. Dewx includes proposal templates with built-in tracking.
How do I handle scope creep that affects invoicing?
Define scope clearly in your proposal with a change order clause. When clients request additions, send a brief change order email: "This additional work falls outside our original scope. Happy to help—it would be an additional $X. Want me to proceed?" Document everything in your CRM so invoicing reflects actual work performed.
