Zoho Invoice Progress Invoice: How to Bill in Stages

Yes, Zoho Invoice lets you create progress invoices for partial billing. You can send an invoice for a percentage of a project’s total value, track what you’ve billed so far, and keep a clear record of remaining balances. This is useful for contractors, agencies, and consultants who work in milestones or phases.

What Is a Progress Invoice and Why Use One?

A progress invoice bills a customer for work completed up to a certain point, rather than waiting for full project completion. Typical uses include:

• Construction projects paid on a monthly draw schedule
• Website or software development billed at milestones (e.g., 30% upfront, 40% at beta, 30% at launch)
• Retainers billed monthly against a larger annual contract
• Consulting engagements with phase-based fees

Progress invoicing improves cash flow, reduces the risk of non-payment on large jobs, and gives clients visibility into how their money is being spent. Zoho Invoice’s built-in feature simplifies the math and record-keeping.

How Progress Invoicing Works in Zoho Invoice

Zoho Invoice does not have a dedicated “progress invoice” button, but it offers the same functionality through its retainer invoice and project billing tools. The two main methods are:

1. Retainer invoices – Create an invoice that bills a fixed amount against a pre-agreed retainer balance. You can apply partial amounts and track the remaining retainer.
2. Project-based billing – If you use Zoho Projects alongside Zoho Invoice, you can log billable hours and expenses, then create an invoice for a selected portion of those logged items.

For a simple percentage-based progress invoice, you can manually enter a line item with a description like “Progress billing – 40% of project” and set the quantity to 0.4, with the unit price equal to the full project amount. Zoho Invoice will calculate the total automatically.

Step-by-Step: Creating a Progress Invoice Manually

If you prefer to control every detail without using projects or retainers, follow these steps:

1. Go to Invoices > New Invoice.
2. Select the customer from the dropdown.
3. Add a line item. In the description, write “Progress invoice – [percentage]% of [project name]”.
4. Set the quantity to the decimal equivalent of the percentage (e.g., 0.35 for 35%).
5. Set the unit price to the full project amount (e.g., $10,000).
6. Adjust the invoice date, due date, and any taxes.
7. Save and send the invoice.

This method creates a clear paper trail. The invoice total will equal the percentage you billed. To track remaining amounts, you can add a memo or use custom fields to note the total contract value and the amount already billed.

Using Retainer Invoices for Ongoing Work

Retainer invoices are ideal when you bill the same customer regularly against a prepaid balance. For example, a marketing agency might charge a $5,000 monthly retainer and send an invoice for $2,500 mid-month for a specific campaign.

To set this up:

• Create a retainer invoice for the full amount (e.g., $5,000).
• When you need to bill a partial amount, create a new invoice and link it to the retainer.
• Zoho Invoice automatically deducts the billed amount from the retainer balance.

This approach works well for ongoing services where the total is known upfront, but payments are made in increments. It also gives your client a clear view of what remains on their retainer.

Common Mistakes and How to Avoid Them

Progress billing can get messy if you don’t plan ahead. Watch out for these pitfalls:

• Forgetting to track cumulative billing – If you send three 30% invoices, you need to know you’ve billed 90% total. Use custom fields or a memo to record “Total billed to date” on each invoice.
• Mixing taxes incorrectly – Progress invoices should apply taxes only to the billed amount, not the full project value. Double-check your tax settings.
• Not linking to a project – If you use Zoho Projects, link each invoice to the project so you can see all billings in one place.
• Ignoring payment terms – Progress invoices often have shorter payment windows. Set clear due dates to avoid delayed cash flow.

Comparing Progress Invoicing to Milestone Billing

Progress invoicing and milestone billing are often used interchangeably, but they differ slightly. Progress invoicing bills based on work completed (e.g., 50% of the job done), while milestone billing bills upon reaching specific milestones (e.g., “design approved”). Zoho Invoice supports both, but the manual method is more flexible for progress billing. Milestone billing can be set up using separate invoices for each milestone, or by using the project module if you link tasks.

Which should you choose? If your client wants to see value delivered before paying, progress billing works. If you have clearly defined deliverables, milestone billing is cleaner because each invoice corresponds to a tangible outcome.

Frequently Asked Questions

Can I automate progress invoices in Zoho Invoice?

Yes, you can use Zoho Invoice’s recurring invoices for fixed-amount progress payments, but for percentage-based progress, you’ll need to create each invoice manually. There is no native “progress percentage” field, but you can use custom fields to track the percentage and remaining balance.

Does Zoho Invoice deduct progress payments from a total automatically?

Not automatically unless you use retainer invoices. With retainers, Zoho tracks the balance. For manual progress invoices, you must update the remaining amount yourself, either in a custom field or in the invoice description.

Can I send a progress invoice for partial work without using Zoho Projects?

Yes. You can create a standard invoice and manually enter the line items. You don’t need the project module. However, linking to a project gives you better reporting and lets you pull billable hours automatically.

What happens if I over-bill a client on a progress invoice?

You can issue a credit note for the overbilled amount and apply it to the next invoice. Zoho Invoice allows you to create credit notes and apply them to future invoices, which keeps the accounting accurate.

Is progress invoicing the same as installment billing?

Not exactly. Installment billing splits a total into equal payments (e.g., 3 payments of $1,000). Progress billing is based on work completed, so amounts may vary. Zoho Invoice supports both, but installment billing is easier to set up with recurring invoices.

Final Thoughts

Zoho Invoice handles progress invoicing effectively, whether you use the retainer feature, manual line items, or project integration. The key is to set up a consistent tracking method so you and your client always know the outstanding balance. Start with a simple manual invoice, add custom fields for total contract value and billed-to-date, and you’ll have a clean system that scales with your projects.
