ClientKit: Invoices & Clients

ClientKit is the offline-first client manager built for freelancers and solo professionals — designers, developers, consultants, photographers, writers, tutors and coaches. Keep every client in one place and move them through your whole workflow: add the client, send a proposal, capture an agreement, invoice the work, and chase the payment — all from your phone, with no monthly software bill and no internet required.

Most freelance CRM and invoicing tools lock you into an expensive monthly subscription and stop working the moment you lose signal. ClientKit keeps your data on your device, works fully offline, and lets you unlock premium once for life — or subscribe if you prefer. Your clients, proposals and invoices are yours.

KEY FEATURES:
• Client manager — full contact list with call, WhatsApp and navigate shortcuts, plus lifetime revenue and outstanding balance per client
• Proposals with a pipeline — build line-item proposals and track them from draft to sent, accepted, declined or expired, with a live win-rate
• Professional PDF invoices — clean, branded invoices with your name, logo, tax and auto-numbered references
• Agreement records with signature capture — capture a client signature on-screen and export a signed agreement PDF for your records
• Payments and outstanding tracking — record payments, see who still owes you and how much
• Payment chasing — send a ready-made, polite reminder over WhatsApp, SMS or email, and get a local reminder on the invoice due date
• AI drafting (optional) — let AI write your proposal cover notes, payment reminders, scope-change notes and follow-up messages in a friendly, professional tone
• Reports and charts — revenue collected, outstanding total, proposal win-rate and monthly income
• CSV export — export your clients, invoices and payments for your accountant or spreadsheet
• Activity timeline — one date-grouped feed of every proposal, invoice, payment and reminder
• Calendar and project tracking — see scheduled work and keep notes and photos per project
• Works in 12 languages with full right-to-left support
