    Questions from Consultants & Agencies

    Yes. SolidInvoice supports quotes that clients can approve. Once accepted, a quote converts directly into an invoice, with no re-entering of data.

    You can record partial payments against invoices and track the remaining balance. This works well for consultants billing project milestones or requiring upfront deposits.

    Yes. Upload your logo, set brand colors, and add company details. Pro and Business subscribers can also remove the 'Powered by SolidInvoice' footer for fully branded client-facing invoices.

    The REST API lets you connect SolidInvoice to your existing tools: CRMs, project management apps, time trackers. You can auto-create invoices from tracked time or sync client data from your CRM.
