There\u2019s no one-size-fits-all answer. The right time depends on your project type and what you\u2019ve agreed upon with your client. Here are five common billing approaches:<\/p>\n\n\n\n
1. Upfront billing <\/h3>\n\n\n\n
In upfront billing, you send an invoice before the project starts, and the client releases upfront payment in whole or in part before you begin. <\/p>\n\n\n\n
Best for:<\/strong> First-time clients, one-off strategy projects, or small projects (less than 2 weeks)<\/p>\n\n\n
\nExamples:<\/strong><\/p>\n\n\n\n
- \n
- 50% to book your slot, 50% before delivery<\/li>\n\n\n\n
- Full payment upfront for a 1:1 consulting call<\/li>\n<\/ul>\n\n\n\n
If you charge upfront, have that conversation during your first meeting or discovery call. You\u2019ll be able to overcome objections or hurdles that would complicate the business relationship from the get-go.\u00a0<\/p>\n\n\n\n
It saves you from investing too much time and energy in a client who doesn\u2019t agree with your payment structure.\u00a0<\/p>\n\n\n<\/div>\n\n\n
2. Milestone-based billing <\/h3>\n\n\n\n
In milestone-based billing, you define project stages and associate each with a payment. At the end of each stage, you typically send an invoice for the services rendered. <\/p>\n\n\n\n
Best for:<\/strong> Projects with clear phases (e.g. branding, website builds, reports)<\/p>\n\n\n
\nExamples:<\/strong><\/p>\n\n\n\n
- \n
- 25% at project start \u2192 50% after first draft \u2192 25% on delivery<\/li>\n\n\n\n
- $X at kickoff \u2192 $Y after design \u2192 $Z after launch<\/li>\n<\/ul>\n\n\n\n
When the project is complicated, consultants prefer the milestone billing<\/a> invoicing process as the client is incentivized to provide timely feedback and approval. The payment process depends on meeting pre-defined goals.\u00a0<\/p>\n\n\n<\/div>\n\n
\n\ud83d\udca1 Pro Tip: <\/strong>A project timeline template <\/a>maps key phases, deadlines, and handoff points. It gives your client a visual roadmap of what to expect and when to pay.<\/p>\n\n\n\n
With dates and deliverables locked in, it\u2019s easier to hold both parties accountable. The template makes the billing process easier and prevents scope creep and payment delays.\u00a0<\/p>\n\n\n<\/div>\n\n\n
3. Post-completion billing <\/h3>\n\n\n\n
In the post-completion billing model, as soon as you complete the work, you invoice clients and add a due date (usually 15\u201330 days).<\/p>\n\n\n\n
Best for:<\/strong> Corporate clients with procurement departments<\/p>\n\n\n
\nExamples:<\/strong><\/p>\n\n\n\n
- \n
- Invoice due Net 15 from submission<\/li>\n\n\n\n
- Work delivered on June 1st, invoice due by June 15th<\/li>\n<\/ul>\n\n\n\n
Post-completion billing is often non-negotiable when working with larger companies. Their finance teams usually follow strict vendor approval and payout cycles.\u00a0<\/p>\n\n\n<\/div>\n\n\n
If you’re using this model, always ensure your paperwork is in place: a signed contract, agreed deliverables, payment details ironed out, and clear payment terms. It\u2019s also wise to factor in payment delays when forecasting your cash flow. <\/p>\n\n\n
\n\ud83d\udc40 Did You Know:<\/strong> 68% of businesses<\/a> experience errors on more than 1% of their total invoices.\u00a0Consider using invoicing software to automate calculations, validate required fields, and keep all client billing details consistent. This reduces manual errors and ensures invoices are approved faster.<\/p>\n\n\n<\/div>\n\n\n
4. Recurring billing (retainers) <\/h3>\n\n\n\n
Ina. recurring billing or retainer model, the client pays a fixed amount at regular intervals (usually monthly), often, but not necessarily for, for a set number of hours or deliverables.<\/p>\n\n\n\n
Best for: <\/strong>Ongoing services (e.g., content, design, advisory, ops)<\/p>\n\n\n
\nExamples:<\/strong><\/p>\n\n\n\n
- \n
- $2,000\/month for up to 10 hours of marketing support<\/li>\n\n\n\n
- Monthly retainer billed on the 1st, paid upfront<\/li>\n<\/ul>\n\n\n\n
This billing method suits clients who need consistent support and don\u2019t want to renegotiate fees every time. For you, it means predictable income and smoother workload planning.\u00a0<\/p>\n\n\n<\/div>\n\n\n
But retainers only work when the scope is clear and respected on both sides. Be sure to define what\u2019s included, how unused hours are handled, and when you\u2019ll revisit the terms, say, every 3 or 6 months.<\/p>\n\n\n

5. Time and materials (hourly billing) <\/h3>\n\n\n\n
In the time and materials billing model (also known as hourly billing), you log time as you go and invoice regularly (weekly, biweekly, or monthly). <\/p>\n\n\n\n
Best for: <\/strong>Open-ended work (consulting, troubleshooting, coaching) and clients with variable time usage<\/p>\n\n\n
\nExamples:<\/strong><\/p>\n\n\n\n
- \n
- $100\/hour billed every Friday with a timesheet<\/li>\n\n\n\n
- 10 hours this week \u2192 invoice sent Monday<\/li>\n<\/ul>\n\n\n\n
Hourly billing gives you flexibility and makes sense when the project scope is evolving or unclear. But you must also justify how time is spent.<\/p>\n\n\n<\/div>\n\n\n
For client satisfaction and to build trust, share regular updates and time logs, especially if the client isn’t seeing immediate deliverables. You can also offer capped hours per week\/month to give clients budget control without locking yourself into fixed fees.<\/p>\n\n\n
\n\ud83d\udca1 Bonus: <\/strong>Here, you can use ClickUp\u2019s Project Time Tracking<\/a> feature to log working hours directly on each task\u2014either by starting a live timer or manually entering time. You can add notes, categorize entries, and generate time reports for invoicing or internal tracking.<\/p>\n\n\n\n
ClickUp also integrates with tools like Harvest<\/strong> and Everhour<\/strong> if you want deeper reporting or to connect it with billing software<\/a>.\u00a0\u00a0<\/p>\n\n\n
