Freelance Invoice Guard — Project & Billing Kit

For freelancers: see finished-but-uninvoiced work, overdue invoices, and unbilled money at a glance — before it quietly becomes money you never got. Freelance Invoice Guard is a lightweight project and billing kit built for solo freelancers who do the work first and bill "later" — and sometimes never. Its whole job is leak prevention. A "Finished — Not Invoiced" view lists completed work with no (or only partial) invoice, together with the total unbilled amount, so finished work can't slip away unpaid. Overdue invoices are flagged automatically by date — overdue is computed for you, and you'll never flip a status by hand. Every job is a single row on one pipeline board that moves from Lead to Paid, so leads, quotes, and contracts are stages, not separate spreadsheets. Payments are recorded per invoice, so partial payments and the balance each client owes are always right. It is lightweight on purpose: just 4 connected databases (Clients, Jobs, Invoices, Payments), realistic fictional sample data included, and set up in minutes. This template requires a free Notion account. Delivery is a digital file containing the template link and simple step-by-step duplication instructions — open the link, click Duplicate, and the template lands in your own workspace.
