Every report you need — configured your way, always up to date.
Tracked hours flow straight into a polished invoice — no copy-paste, no manual math.
Draft an invoice on a laptop, check the total on a phone, and send the PDF from a tablet. The fields must stay identical on every screen. A small team may have one person enter line items and another approve the final version before sending it.
The outcome is a finished invoice with the same invoice number, buyer details, line items, tax line, payment terms, and remit-to information on every screen. Multi-device access matters most when billing happens between tasks, after client calls, or at month-end, where a missing update creates duplicate invoices or inconsistent totals.
For ordinary United States private-sector businesses, there is no prescribed federal invoice form. Invoices mainly support recordkeeping, contract terms, and payment collection. IRS Publication 583 treats invoices as supporting documents that help show business transactions and the amounts and sources of gross receipts, so the invoice should be clear enough to support the sale later.
A complete invoice usually includes seller and buyer names, addresses or contact details, a sequential invoice number, issue date, due date, line items, quantity, rate, subtotal, tax line where applicable, total due, payment terms, and remit-to details. An invoice is different from a receipt, estimate, or quote. A receipt proves payment received, while an estimate or quote gives a pre-work price offer.
The main multi-device risk is version drift. One person updates the due date on a phone, another edits the line items on a laptop, and the client receives a PDF that no longer matches the internal record. A practical workflow uses one current invoice record, clear draft and sent states, and a final PDF that does not change after delivery.
Sales-tax treatment deserves extra care because the United States does not use a national VAT or GST invoice regime. State and local sales and use tax rules control taxability, rates, and collection duties. Service taxability varies by state and service type, and remote-seller nexus rules also vary, even though South Dakota's law in Wayfair used more than $100,000 in sales or 200 transactions annually.
A one-off invoice tool is enough when you need a clean invoice for a single client, a small number of line items, and a payment request that will not be reused. It also works when you already know the correct tax treatment, payment terms, invoice number, and buyer details before you start.
A managed workflow matters when tracked billable time and project costs feed the invoice. Everhour supports billable and non-billable time through project billing status, task-level non-billable controls, custom task rates, member-rate exceptions, and admin reports for billable time, non-billable time, billable amount, and cost, so the invoice can start from approved work instead of copied notes.

Yes. A multi-device invoice workflow lets you draft, review, and send invoices from different screens while using the same invoice record. The key control is version consistency. The invoice number, line items, tax line, payment terms, and total due must match the final document sent to the client.
Sequential invoice numbers, issue dates, due dates, buyer details, seller details, line item descriptions, quantities, rates, subtotal, tax line, total due, payment terms, and remit-to details prevent most disputes. Clear fields matter more when multiple people or devices touch the invoice before it is sent.
No. The United States does not use a national VAT or GST invoice regime. Sales and use tax obligations are imposed by state and local jurisdictions. A seller should use the applicable state and local tax treatment instead of adding a generic VAT or GST field to a United States invoice.
Yes. A phone-edited invoice can create mistakes when a draft is changed after someone has already reviewed or exported it. Common problems include duplicate invoice numbers, outdated due dates, missing discounts, and line items that no longer match the final PDF sent to the client.
No. Federal contracts are a national exception. FAR 32.905 defines proper invoice fields for federal procurement, including contractor details, invoice date and number, contract or order references, line items, terms, payee information, contact details, and TIN or EFT banking data when agency procedures require them.
Everhour lets admins set project billing status, mark specific tasks as non-billable, use custom task rates, and set member-rate exceptions. Admin reports can show billable time, non-billable time, billable amount, and cost, so invoice totals are based on categorized work instead of manual sorting.
Everhour reports can include invoicing-related columns alongside billable time, non-billable time, estimated cost, revenue, and profit. Teams can use those reports to review invoiced and uninvoiced work before client billing or export report data for spreadsheet review.
Track billable and non-billable work before billing starts. Everhour turns project time, task rates, and admin reports into cleaner invoice preparation.
