Free tools for estimates and invoices

Small, exact and free: the sums a one-person business does before writing an estimate or after sending an invoice, and blank documents that open straight into the app. Every calculator shows its working, none of them rests on a rate that changes each April, and nothing here needs an account.

Calculators

Calculator Hourly rate and day rate calculator Work out what to charge per hour and per day from what you need to earn, your overheads, and the hours you can actually bill, not the hours you work. Calculator Margin and markup calculator Margin and markup are not the same number, and getting them the wrong way round is the commonest pricing mistake there is. Convert one to the other and price for the margin you want. Calculator Invoice due date calculator The date an invoice falls due from its issue date and terms, and how many days late it is today. Net 7, 14 and 30, or any number of days. Calculator Deposit and staged payment calculator Split a job into a deposit and stages by percentage and get amounts that add up to the total exactly, pennies included. For kitchens, extensions and anything that runs for weeks.

Documents

Document Free invoice generator Make a professional invoice in your browser: numbered, with VAT worked out, as a PDF or a link your client can pay from. No account and nothing to install. Document Free estimate and quote generator Write an estimate or quote in your browser, send it as a link the customer can approve and sign, and turn it into the invoice with one click when the job is done. Document Pro forma invoice generator Make a pro forma invoice to ask for payment before the work: clearly marked, not a VAT invoice, and turned into the real invoice with one click when the money arrives. Document Credit note generator Correct an invoice you have already sent with a credit note: its own number, the invoice it reverses named on it, the VAT worked out, and the balance shown on the original. Document Purchase order generator Raise a purchase order to a supplier or subcontractor: numbered, itemised, sent as a PDF or a link, and recorded as an expense against the job when the bill comes in. Document Delivery note template A delivery note with the items and quantities, no prices, a space to sign, and its own number: made from the invoice or the order so the two can never disagree. Document Rent receipt generator Make a numbered rent receipt for a tenant: the amount, the period it covers, the date paid, and a running record of every payment, as a PDF or a link. No account. Document Freelance quote and deposit builder Scope a project, set milestones and a deposit, and send it as a link the client approves by name. It becomes the invoice when the work is done. No account, no per-send fee.

Each tool links to the guide that explains the sum behind it. The guides are where the reasoning lives; the tools are the arithmetic, done once and done right.
