Bill the Part of the Contract That Is Due

A contract invoice requests payment under an existing agreement. It may cover completed services, an agreed milestone or a billing period. The contract explains the arrangement; the invoice shows the charge that is due now.

Name the contract and the work covered by this bill. For ongoing work, state the service dates so the customer can tell one invoice from the next. Include future work only when the agreement calls for payment in advance.

How to Create a Contract Invoice

Check the agreement before you start. Use its prices and billing schedule for this invoice.

1 2 3 4 5 6 7

1. Add Your Business: Use the business name and billing contact shown in the agreement.
2. Add Your Logo: Choose a logo the customer recognizes from your contract documents.
3. Select the Customer: Address the invoice to the person or business responsible for payment.
4. Check the Number and Dates: Use a unique invoice number. Set the invoice date and agreed due date.
5. Describe the Current Charges: Name the completed services, milestone or period. Add the agreed quantities and prices.
6. Check Taxes and Totals: Apply any relevant tax or agreed discount. Docelf calculates the invoice total.
7. Reference the Agreement: Add the contract number and payment instructions in Terms and Conditions. Review the invoice, then email it or download a PDF.

How to Fill In Contract Invoice Line Items

Use descriptions the customer can match to the agreement. Put approved extra work on a separate line instead of folding it into the regular charge.

This fictional September maintenance bill refers to contract M-212. It includes four scheduled visits and an approved repair. All amounts are in USD, with an illustrative 8% tax on each charge.

This invoice bills the September visits and approved repair, not the full contract value. Replace the sample prices and tax with those that apply to your agreement.

What to Include in Contract Invoice Terms

The Terms and Conditions field should point back to the agreement, not rewrite it. State the contract reference and payment deadline. Keep the wording consistent with the period or milestone you have billed.

Do not add new fees or conditions just because a template has space for them. Use only the agreed terms that apply to this bill. Check local requirements for any fee or warranty wording. This example covers the maintenance bill above.

Make the Billing Period or Milestone Easy to Find

For ongoing work, include the start and end dates in the service description. For a milestone, use the milestone name from the agreement and describe what you completed.

A fixed monthly fee and an hourly charge need different descriptions. Use quantity 1 for an agreed period fee. Use hours and the agreed hourly rate when that is how the contract prices the work.

Reuse the Invoice for the Next Billing Period

For another billing period, duplicate the invoice to create a new draft with a new number. Update the service period, invoice date, due date and current charges before sending. Remove one-time charges, such as the repair in the example above, unless you provided them again. You choose when to prepare and send each bill.

Record each payment on the invoice it covers. Do not apply the same payment to a later billing period.

Give the Customer the References They Need

Attach a PDF or image of a work summary when the customer needs support for the charges. Keep the contract number in the invoice text as well, so it is easy to find.

Use your logo, colors and fonts consistently. An optional industry name can appear before “Invoice,” and the footer can hold your billing contact. Choose the contract currency from USD, EUR, GBP, CAD or AUD.

Follow the Contract Bill Through Payment

After you email the invoice, check its history in Docelf. You can see when it was delivered and when the customer opened it. Check these details before following up on an unpaid bill.

Record the amount and date of each payment. Docelf shows the remaining balance and marks a fully paid invoice Paid. You can create a receipt after recording payment.

Contract Invoice FAQs

• Is a contract invoice a replacement for the contract?

  No. The contract describes the agreement. The invoice requests the payment due under it. Reference the contract and keep the billed work, dates and payment terms consistent with that agreement.

• Should I bill the full contract amount on every invoice?

  No. Bill only the work, milestone or period due now. Include future work only when the agreement calls for an advance payment.

• How should I describe a monthly contract fee?

  Name the service and the billing period. Use quantity 1 and the agreed fee for that period. Update the dates on the next invoice so the customer can tell the bills apart.

• Can I add work outside the contract?

  Put separately approved work on its own line with a clear description and agreed price. Include the approval reference when useful. Keep that charge separate from the regular contract fee.

• Can I reuse an invoice for the next billing period?

  Yes. Duplicate it in Docelf to create a new draft with a new number. Check the customer, dates and current charges before sending. You prepare and send the next invoice yourself.

• Can I include a work summary with the bill?

  Yes. Docelf supports PDF and image attachments. Attach the relevant summary and keep the contract reference on the invoice itself. Each attachment can be up to 5 MB.
