Expenses are added to invoices automatically

Each expense you pay goes on the next client invoice, with its receipt and your fee.

Bill by percent complete, cost plus, or both on the same invoice.

The invoice is ready before billing day.

  • Every cost you pay on a cost-plus scope of work is on the next invoice, so you profit on every invoice.
  • A fixed-price project can bill a change order at cost plus on the same invoice, with no second document.
  • Your client pays online from the invoice link, and you are notified when the money is available to spend, typically within 5 business days.

Expenses automatically added to invoices
Keep billable costs with their receipts
On a cost-plus scope of work, each paid and coded expense goes on the draft invoice. Review the expenses with their receipts before you bill your client.
Issue invoices easily
Review the draft before you issue it
Check the progress, expenses, fees, and credits on the draft against the earlier invoices before you issue it. Your client then gets a PDF by email and a link to pay.
Client invoice payment options
Let your client review and pay online
Clients sign in, open the invoice, review the charges, and pay from their connected bank account. The invoice shows the amount paid and any balance remaining.
Bank payment setup
See which project each payment belongs to

Next: Track the project

Percent complete, cost plus, or both on the same invoice.

For a fixed-price scope of work, bill the share of the agreed price completed since the last invoice. For a cost-plus scope of work, bill the expenses you paid and your agreed fee. A fixed-price project can bill a change order at cost plus on the same invoice.

Before Buildplus I would have to send my subcontractors multiple payments spread out over a couple of days to avoid hitting electronic transfer limits.

Now I can send one payment and be done. That convenience combined with the fact that payments are automatically tracked back to the right subcontract makes Buildplus a very elegant solution.

FAQs

Can I bill fixed-price work and cost-plus extras together?

Yes. One invoice can include progress against agreed scope prices and eligible costs with agreed fees. For example, bill progress on the main project and a cost-plus change order together. If an allowance item is billed at cost plus a fee under your agreement, you can include that charge too. Allowance terms vary; agree how to bill the item with your client.

Can I use Buildplus for fixed-price projects?

Yes. Bill progress against the agreed price of each scope of work. Review amounts previously billed, the current invoice, and the remaining balance. Expenses track the cost of the work without changing the agreed client price.

How quickly will client payments arrive?

An invoice payment takes 1 to 5 business days to arrive. Buildplus sends a notification and updates the invoice and the project account as the payment moves.

Do clients need a Buildplus account to pay?

Yes. Your client makes a free account one time, then opens each invoice link, reviews the charges, and pays online. The same account shows your client the billing progress of the project. Role-based permissions control what your client can see, from invoices to the budget.

Can I add expenses after creating an invoice?

Yes. Keep recording and reviewing project expenses as they arrive. On cost-plus projects, eligible costs can go on a later invoice. On fixed-price projects, those expenses update the cost record while billing follows agreed prices and progress.

Can I still use my existing bank account?

Yes. Buildplus can track connected external accounts for expenses, while project accounts and invoice payments keep the money for each project in one place.
