🚨 The $5,000 Mistake
Sarah, a talented web designer, lost a $5,000 project because she sent an invoice instead of a proposal. The client was confused, felt pressured, and went with a competitor who properly presented their services.
Don't be Sarah. Understanding the difference between proposals and invoices isn't just about paperwork—it's about winning business and getting paid properly.
📚 Simple Definitions
Proposal
A document you send before starting work to outline what you'll deliver, how you'll deliver it, and what it will cost.
Invoice
A document you send after completing work to request payment for services already delivered.

🤔 Frequently Asked Questions
Can I use the same tool for both proposals and invoices?
While some tools handle both, specialized tools often work better. Proposal tools focus on selling and persuasion, while invoicing tools focus on payment processing and accounting. Many professionals use Propovo for proposals and QuickBooks/FreshBooks for invoicing.
What if my client asks for changes after I send the proposal?
This is normal! Update your proposal with the changes and send a revised version. Once approved, that becomes your working agreement. Never send an invoice until the proposal is fully approved and work begins.
How long should I wait before sending an invoice after proposal approval?
This depends on your payment terms. Some freelancers invoice immediately for a deposit, others invoice upon completion. Always clarify payment schedule in your proposal and stick to it.
Should my proposal include detailed pricing like an invoice?
Yes, but present it differently. Proposals should show investment and value, while invoices show costs and payment details. In proposals, focus on what the client gets for their investment.
