The practical answer

A useful billing estimate starts with completed, eligible work for the right client and period. Match each item to its service rate, check quantity, exclude work already invoiced, then review any discount and tax assumptions separately.

Separate the delivery record from the invoice

It is easy to remember the big project and forget the smaller deliverables inside it. A task list becomes a reliable billing starting point when each finished item has a clear service classification and quantity. That does not mean everyone needs to see service prices. Delivery information and financial access serve different purposes.

In besteam, contributors select the kind of work and enter quantity. Financial choices and rate-card details are reserved for authorised users. The workspace owner can grant the required access to someone helping with billing.

Choose a client and a meaningful period

On the billing estimate, choose a date range and client, then narrow to particular projects if needed. The date basis is a deliberate choice: completion date answers what finished in the period; a billing-date override supports a specific agreed billing allocation. By default, the billing date follows the actual task completion date.

An estimate does not need the recipient address or place of supply needed later for an invoice. It should answer “what is this completed work worth?” without asking the billing person to fill out the entire invoice first.

  1. Choose the client and From/To dates.
  2. Choose the date to match and optional projects.
  3. Calculate and review the included work and any pricing gaps.

Check the rate, the quantity and the counting level

Suppose a service rate is ₹200 per slide and a completed task records twenty slides. The illustrative pre-tax charge is ₹4,000. Another task with six images at an agreed ₹500 each contributes ₹3,000. Together they produce ₹7,000 before discounts and taxes. These are example rates, not besteam subscription prices.

Do not count the same deliverable twice. If a parent task represents the entire presentation, charging its twenty slides and also charging every slide sub-task would overstate the work. Decide which level represents the billable output and review the include-in-billing choices accordingly.

Resolve a partial estimate before relying on the total

A missing service rate or an item requiring a custom quote means the estimate may be incomplete. Review those exceptions rather than treating the visible subtotal as the entire amount earned. Check that the service unit matches how the team entered quantity.

An estimate is a review tool, not an accounting guarantee. Work that is incomplete, outside the selected range, already invoiced or explicitly excluded from billing should not be treated as new eligible revenue. Keeping completion status accurate is part of keeping the estimate useful.

Convert the reviewed work into an invoice

Once the estimate is checked, prepare the invoice with the required client and business details. You can present each eligible item or consolidate the charges as Project Execution Charges. Review discounts, tax treatment and applicable codes for the transaction before issuing the invoice.

Keep the source work available for questions. A consolidated presentation can be convenient for the client, while the internal item-level review helps explain how the amount was calculated. Export the visible estimate or invoice table to Excel when a finance colleague needs to review it.

  1. Resolve missing or custom rates.
  2. Review tax and recipient information with the responsible person.
  3. Keep a clear connection between the invoice and the work being charged.

Common questions

Does an estimate require client invoice details?

No. The estimate needs the relevant client, date range and optional project filters. Invoice recipient and tax details are reviewed when preparing the invoice.

Who can update rates?

The workspace owner and people explicitly granted rate-card access. Task quantity remains available to authorised task contributors.
