Generating professional invoices from tracked time

Generating professional invoices from tracked time Timether can turn your tracked billable time into a professional invoice. Instead of manually calculating hours, rates, and totals, you can select a client, project, and date range. Timether will find the matching billable time entries and prepare the invoice for you. Creating an invoice To create an invoice from tracked time: 1. Go to the Invoices section in your workspace. 2. Click Create Invoice or New Invoice. 3. Select the client you want to invoice. 4. Select the project, if the invoice should be limited to a specific project. 5. Choose the date range for the work you want to include. 6. Review the billable time entries found by Timether. 7. Add tax or discount options if needed. 8. Choose an invoice design. 9. Save the invoice as a draft. Once the invoice is created, Timether will calculate the invoice line items based on the selected billable time. How Timether selects time entries When you generate an invoice, Timether looks for time entries that match the selected client, project, and date range. Only time entries that are both billable and uninvoiced will be included. This means Timether will not include: - Non-billable time entries - Time entries outside the selected date range - Time entries from a different client or project - Time entries that have already been added to another active invoice This helps prevent duplicate billing and keeps your invoices accurate. Reviewing invoice line items After Timether finds the matching time entries, it aggregates them into invoice line items. These line items show the work being billed, the tracked duration, the rate, and the calculated amount. Before finalizing the invoice, review the included entries carefully. This is a good time to check descriptions, dates, durations, billable status, and rates. If something looks incorrect, you may need to adjust the original time entry before sending the invoice. Adding tax You can add a tax rate to the invoice as a percentage. For example, if your invoice requires tax, you can enter the relevant tax percentage and Timether will calculate it on top of the invoice subtotal. The tax amount will be shown separately so the client can clearly see how the final total was calculated. Adding discounts Timether also supports invoice discounts. A discount can be added as either: - A flat amount - A percentage A flat amount discount subtracts a fixed value from the invoice. A percentage discount reduces the invoice based on a percentage of the subtotal. Use discounts when you need to apply a client adjustment, promotional offer, correction, or agreed reduction. Choosing an invoice design Timether includes different invoice designs so you can choose the style that best matches your work or brand. The available invoice designs are: - Classic - Minimal - Brand The Classic design gives your invoice a familiar professional layout with clear sections and standard invoice formatting. The Minimal design is cleaner and simpler, with less visual weight and a more lightweight presentation. The Brand design is useful when you want the invoice to feel more aligned with your workspace or business identity. You can choose the design before generating or exporting the invoice. Invoice statuses Invoices move through different statuses depending on where they are in the billing process. Each status affects what can be edited and what happens to the time entries connected to the invoice. Draft invoices A Draft invoice has been created but not finalized or sent yet. Draft invoices are still editable, but the time entries included in the draft are locked while they remain attached to the invoice. This prevents accidental changes to tracked time that is already being prepared for billing. If you need to edit a locked time entry, remove it from the draft invoice first or void the invoice if it is no longer needed. Sent invoices A Sent invoice has been emailed, downloaded, or otherwise prepared for the client. Sent invoices remain locked to protect the billing record. The time entries connected to a sent invoice cannot be edited or deleted while they remain attached to the invoice. This helps keep the invoice total consistent with the underlying time records. Paid invoices A Paid invoice is marked as settled. This status is used when the client has paid the invoice and the billing cycle for that invoice is complete. Paid invoices remain part of your billing history and keep the connected time entries locked. Void invoices A Void invoice is cancelled. Voiding an invoice releases the time entries that were locked by that invoice. Once the invoice is voided, the released time entries can be edited, deleted, or included in a new invoice if needed. Use void when an invoice was created by mistake, should no longer be used, or needs to be replaced with a corrected invoice. Why time entries are locked after invoicing Timether locks invoiced time entries to keep billing records reliable. If a time entry has been included in a draft, sent, or paid invoice, changing that entry could change the invoice total or create a mismatch between the invoice and the tracked work. Locking helps prevent accidental edits and protects both your records and your client-facing invoices. If changes are needed, void the invoice or detach the related line item before editing the time entry.

Understanding invoice locking rules

Understanding invoice locking rules Timether locks time entries after they are added to an active invoice. This helps protect your billing records and prevents accidental changes that could create mismatches between tracked time and invoice totals. Why time entries become locked When a time entry is added to an invoice, it becomes part of a billing record. If that time entry was changed later, the invoice amount, project details, or billing history could become incorrect. For example, changing a time entry after invoicing could affect: - The total duration billed - The project connected to the work - The hourly rate - The billable amount - The invoice subtotal or total - Reports connected to invoiced work To prevent these issues, Timether locks time entries that are connected to active invoices. The core locking rule Any time entry associated with an active invoice cannot be edited, moved to another project, or deleted. This applies to invoices with these statuses: - Draft - Sent - Paid As long as the invoice is active, the time entries attached to it stay locked. What you cannot do with a locked time entry When a time entry is locked by an invoice, you cannot: - Edit the description - Change the duration - Change the date or time - Move it to another project - Change its billable status - Change its rate - Delete the entry This keeps the invoice and the tracked time consistent. Draft invoices also lock time entries Even if an invoice is still in Draft status, the time entries included in that invoice are locked. This is because the invoice is already using those entries to calculate its totals. If the entries were edited while the draft exists, the invoice could become inaccurate or inconsistent. Sent and paid invoices Time entries connected to Sent or Paid invoices are also locked. A sent invoice may already have been shared with a client, and a paid invoice has already been settled. For this reason, Timether protects the original billed time from being changed after the invoice has moved forward in the billing process. How to unlock time entries To edit a locked time entry, it must first be released from the invoice. There are two main ways this can happen: 1. Delete the invoice, if it is still a draft. 2. Change the invoice status to Void. Once the time entry is no longer attached to an active invoice, it is released back to the uninvoiced pool. After that, the time entry can be edited, moved, or deleted again. Deleting a draft invoice If the invoice is still in Draft status and was created by mistake, you may be able to delete it. Deleting the draft removes the invoice record and releases the attached time entries. Those entries can then return to the uninvoiced pool and become available for editing or future invoicing. Voiding an invoice If an invoice has already been sent, paid, or should no longer be used, you can change it to Void. Voiding cancels the invoice and releases the locked time entries. Once voided, the entries can be corrected and included in a new invoice if needed. Use void when an invoice needs to be cancelled, replaced, or recreated with corrected details. What happens after entries are released After locked entries are released from a deleted draft or voided invoice, they return to the uninvoiced pool. This means they can be: - Edited - Moved to another project - Deleted - Included in a new invoice This gives you a safe way to correct mistakes while still protecting active billing records. Why this matters Invoice locking helps keep your records reliable. It prevents invoicing mismatches, billing disputes, and data discrepancies between tracked work and client-facing invoices. If you need to make changes, first release the time entries by deleting the draft invoice or voiding the active invoice. Then make the required corrections and generate a new invoice if needed.
